Would you wear sunglasses that double as headphones?

Google Glass may be on hiatus, but our appetite for high-tech spectacles endures. One of the latest efforts comes in the form of a Kickstarter campaign for a pair of sunglasses that double as wireless headphones.

Buhel’s Bluetooth SG05 SOUNDglasses obliterated their $80,000 fundraising goal a mere 48 hours after launch, ending up with more than $400,000 by the end of the campaign. “SOUNDglasses give you innovation, freedom, safety, and easier life,” Buhel promises.

Great, but how will the music sound?

Thanks to “bone conduction technology,” SOUNDglasses let users listen to music, conduct a phone conversation, or talk to computerized personal assistants like Siri without the “impediment” of earphones. Two speakers situated in the glasses near the wearer’s temples send vibrations through the bones of the head and into the inner ear. A built-in microphone picks up what the wearer says.

This isn’t exactly revolutionary. Many hearing aids transmit sound with bone conduction, as do other headphone brands. But a main complaint for these kinds of headphones is that the sound quality leaves a lot to be desired. Will these be any different?

Here’s how the creators of SOUNDglasses address that question: “We don’t pretend that Bone Conduction is your perfect HiFi music companion, but we can say that it serves a specific purpose, which increases your safety in an infinite number of situations. The military and Google chose Bone Conduction for some of their devices…They must have thought it was not that bad, and so did nature with dolphins and whales.”

Hmm. Not the most reassuring comment, is it?

Buhel is pushing the safety angle hard to make up for any lousy sound quality. Because nothing has to actually go inside the ear for this technology to work, wearers will still be able to hear the sounds going on around them. This is a plus for what seems to be Buhel’s target demographic: athletes. It would be great to be able to bike down the busy avenues of Manhattan blasting some excellent riding tunes without losing access to one of your most vital senses.

Another problem: using these headphone-less glasses to have a phone conservation could produce some funny looks from passersby. To convince people to accept this kind of public embarrassment, any headphone-glasses combo will have to be excellent in every other way. Sound quality is important, but equally essential is style.

The SOUNDglasses come in a variety of colors and lens shades, and from the outside seem no different from your average sporty shades. This is rule number one for smart glasses: they have to be something you actually want to wear in public. Google found this out the hard way. Not even its own developers wanted to wear the goofy-looking face computer. Of course, SOUNDglasses don’t actually project any visual effects into a wearer’s line of sight, which probably eliminates some of the encumbering hardware that could inhibit a sleek design.

What would make these glasses better is if they came in a variety of frame styles. Right now, the only design on offer looks best on athletes and outdoor explorers, but doesn’t have much fashionable appeal otherwise. Google Glass got a trendy redesign to provide some fancy frame options because it knew it needed to look less geeky if it wanted to be worn by anyone other than, you know, geeks. The same goes for SOUNDglasses, especially if it wants to catch on with anyone other than athletes.

The first shipment of glasses to Kickstarter backers is slated for May of 2015. If you want to wait for the first reviews to roll in before buying, they will retail for “more than $270″ later in the summer.

Well if you had said to us, how about a sunglasses/headset mash-up we would have thought you were mad! but this kickstarter, using bone conductive technology, too which we have lots of knowledge about, We’re looking forward to receiving our pair when they are dispatched.

In Your Dreams: Bloke Dreams About Winning The Lottery, Actually Manages It …But Then Has To Give Half Of It Away…

Back in 2012, Fatih Ozcan, a waiter working at the Kucukkoylu Turkish restaurant in York, apparently experienced a prophetic dream which involved him holding huge bundles of cash in both hands, whilst his boss, Hayati Kucokkoylu (either the restaurant is named after him or its an amazing coincidence) was standing in front of him.

Mr. Ozcan interpreted this dream as meaning that, if he played the lottery with his boss’ money, he’d win huge bundles of cash.

…Well, he was half right.

At work the next day, Mr. Ozcan pestered his boss to buy a few ‘Euromillions’ tickets, using money from the till. The boss eventually relented, suggested some numbers and gave him some cash.

…Amazingly, Ozcan later checked his ticket to find that he had won a Million quid.

When Fatih told Hayati of his fortunes, the boss decreed that all of the money was, in fact, his by right, as his money had paid for the majority of the tickets. Ozcan, for his part, was having none of it, and a major falling out occurred between the two men.

Eventually, the argument ended up going to court, where a judge (with apparently more sense than either man combined), decreed that the winnings should be shared 50/50 between the man that had supplied the ticket and the man that had paid for it.

Sounds fair, right? I mean both men still get a £500,000 payday out of it.

In summary, the waiter had the dream, stumped up a little cash and picked a few numbers. The restaurant manager donated the most cash (the princely sum of £9) and also picked a few numbers himself.

It really isn’t rocket science. 50/50 seems pretty fair to me…

Apparently that wasn’t the end of the debacle, though, as Kucukkoylu appealed the decision and took the issue to the London Civil Appeals Court, in the hopes of walking away with the full Million.

This month, after three years of legal wrangling, yet another judge told him to ‘bugger off and stop being so bloody greedy’ (albeit probably using more fancy language than that). The judge then declared that the fairest course of action was (you guessed it) to split the money 50/50, which pretty much any reasonable person would have already done anyway.

According to Kucukkoylu, he chose the numbers and paid for the ticket and thus, the money should rightly be his, however, without his employee having the dream in the first place, he never would have bought a ticket.

The really pathetic part of this story is that neither man appears to be happy with getting a £500,000 payday – and thus both saw fit to fight over it in court for three years, presumably spending loads on their legal fees.

…Seriously, where’s the logic?

Its hard to decide whether these men are simply greedy and stupid, or just stupid and greedy. Either way, it isn’t good.

As for the (presumably now fired) waiter – let’s just hope any dreams about seven fat customers devouring seven lean ones turn out to simply be a case of eating too much cheese before bed!

Earphones and headphones market – global industry analysis and opportunity assessment 2014 – 2020 scrutinized in new research

We have seen a huge demand for headset and headphones over the last few years, helped by the emergence of luxury brands like Dr Dre beats range. You can find the original article on this website.

The demand in the region is lead by the countries such as China, India, South Korea, and Japan. Latin America is also expected to experience significant growth of earphones and headphones market driven by growing number of portable devices in the region.

Portable music systems such as smartphones, tablets, and portable music players are experiencing significant growth in demand and this in turn is driving the growth of earphones and headphones market. The global market for headphones and earphones is anticipated to experience considerable growth over the coming years.

In the recent years, the technological advancements in headphones have led to minimization of the overall weight of the headphone. Additionally, sophisticated noise cancellation features in earphones and headphones have been aiding in the rising popularity of these devices.

Major technological developments in wireless such as Wi-Fi, Infrared (IR), SKAA and Bluetooth are expected to continue driving the growth of earphone and headphones market.

Shifting consumer trends toward the adoption of headphones/earphones during working out is also giving a push to the growth of this market. Moreover, companies are targeting youth through introduction of new and innovative features.

The increasing availability of low cost counterfeit products poses a significant challenge to the growth of earphones and headphones market.

In the Asian countries such as China, India, Taiwan and Indonesia, there is a significantly large unorganized market for earphones and headphones.

This unorganized market often sells counterfeit and low standard products at a significantly lower cost poses a serious challenge to the organized players in terms of revenue and demand. Addition of features such as voice recognition represents a significant future growth opportunity in this market.

Based on product types, the headphone and earphone market includes wireless speakers, wireless headphones, and microphones. The headphones can be further categorized into in-ear buds, gaming headphones, over-ear headphones, wireless headphones, and clip-on headphones.

North America has been the leading market for earphones and headphones owing to significantly large penetration of portable devices. Further, the region also has significant demand for high end earphone and headphone products leading to higher revenue generation.

Asia Pacific is anticipated to be the fastest growing market for earphones/headphones owing to boom in the portable/mobile devices market in the recent years. The region is experiencing rapid growth in demand for smartphones which is driven by increase in disposable income of a significantly large population.

Formula One Pit Crews Embrace 3D Printed Noise Cancelling Earpieces From Minerva Hearing

The sound of a racing motor at full throttle is a singularly powerful noise. While changes in Formula One motors, from V8s to the turbocharged 1.6-liter V6 motors of this season, mean they generate 15,000 RPM, which is 3,000 RPM less than last year, and though the smaller engines have made them significantly quieter, they’re still loud.

Now that scientists are warning people around the world of the dangers of prolonged exposure to high levels of noise, a Welsh company is using 3D printing to create earplugs to prevent hearing damage to everyone from musicians to Formula One mechanics.599468_513770338658254_1536909041_n

As a point of reference, you can tolerate the noise generated as you ride in a car – around 85 dB – for about 8 hours before hearing damage begins to occur. An average motorcycle generates 95 dB, and you can take about 47 minutes of that, and a loud rock concert can pound out 115 dB.

While the new generation of F1 cars creates some 80 dB of sound, the old V10-based cars pumped out 130 dB. At a level of 128 dB, your hair can actually begin to detect vibration from sound, and at those levels, hearing can be altered in a matter of seconds. A very small hand grenade or bomb can create up to 210 dB.

All this is important as one part of the inner ear, the cochlea, contains some 17,000 small hair cells called stereocilia which float inside cochlear fluid. When sound waves enter the cochlea, the stereocilia move, and that triggers an electrical impulse in the auditory nerve. The nerve passes those electrical impulses to the brain where they’re decoded as “sounds.”

Here’s the problem: once damaged, stereocilila don’t grow back.

Kevin Davies, operations director at Minerva Hearing Protection in Cardiff, Wales, says his company’s custom hearing protection devices built with 3D printing technology have been used for everything from providing protection for the pit crews on the F1 circuit to musicians on stage.

The products are custom molded to an individual’s ear canal to completely eliminate external sounds, and they’re formed in 3D printed hard acrylic. The earplugs feature tiny, built-in acoustic filters which take into account the natural response of the ear.IF

“With Formula cars producing volumes over 100dB under race conditions, multiplied many times over in a busy Grand Prix pit lane, the need for hearing protection as well as safe communication are paramount,” Davies says. “We have been working with the majority of Formula 1 teams over the past three years, and we are really proud to be part of a world that demands the highest standards of engineering technology.”

The devices are made from a soft, medically-approved silicone, and they can also be made from a firmer acrylic material which can be plated in silver, gold, or titanium.

The production process begins with a technician making an impression of a client’s outer ear canal, and then pouring in liquid silicon. The resulting molds are then digitized for input into a 3D printer, and the company says it produces more than 4,000 ear pieces per week. Davies says 3D printing technology has advanced well beyond simply the ability to produce prototypes.

1889080_698346236867329_8772122851610298217_oThe company has produced more than one million 3D printed products at their Cardiff manufacturing center. Minerva was one of the first companies to embrace additive manufacturing as a commercial proposition, and Davies says they acquired their first 3D printer in 2004 “at a cost in excess of $150,000.” They also receivedMHRA approval for medical-grade resin they use to 3D manufacture the ear-pieces.

“Having been one of the first UK producers to take the plunge and switched over entirely to this form of additive manufacturing, we believe we have proven the case for 3D printing as a serious manufacturing process,” Davies says. “It has well and truly arrived as a cost-effective and efficient production technology that brings us many advantages, and has truly stepped out of its technological novelty phase of recent years. We will continue to invest in new and improved 3D systems ensuring our products stay at the leading edge of our field.”

Davies says 3D printing technology has also helped Minerva produce over 8,000 variations of color and materials, and he adds that in-ear monitors and ear plugs are now laser-printed with logos, names, or images according to a customer’s preference.

Additional InformationAs we see the advent of 3D printers we will see more and more products that are relatively expensive to produce in small quantities and to see one of the most technologically advanced sports using this shows that it will have a bright future, you can find the original source of the article here

Can constantly wearing headphones cause baldness?

No, wearing headphones, no matter how often you do it, will not cause hair loss.

This idea is tied in to the same popularly held falsehood that states that constantly wearing a hat can cause hair loss (and even premature baldness). This is, of course, completely untrue.

Here, from Health Central.com, is a particularly good rebuttal to this old wives’ tale, it deals with a case study of a man named Mark.

“One of the myths surrounding hair loss is that wearing hats will cause or contribute to premature baldness. Fortunately, for men like Mark, this is not true. There is no scientific research that shows wearing a hat contributes to hair loss. In order for a hat to cause hair loss, it would need to be tight enough to cut off circulation to the hair follicles”.  

However, you may wonder why there is hair in your hat when you take it off (and sometimes rather a lot of it)? Well, according to Health Central,

“One of the reasons many people believe that hats cause hair loss is because of the amount of hair left inside a hat when you take it off. Whenever you see this, you might worry that your hair is quickly falling out. But we lose hair every day, as much as 80 to 100 strands daily. Usually, you will see this as you comb and brush your hair or when you shower. However, your hats may catch some of this hair and as it builds up over time, it may seem as if there is a lot of hair in your hat”

We suspect it also has to do with the psychological reactions to natural conditions like male pattern baldness (or androgenetic alopecia). For example, the person believes that there must be an outside factor causing his hair loss, because it can’t be that he is simply going bald for no visible reason. Our hypothetical man tells himself that he’s strong, he’s virile and he’s still a young man – he can’t possibly be going bald, there must be some other reason for it. Hair loss can be quite traumatic and damaging to a person’s self image and baldness is often (wrongly) associated with getting older and less attractive.

In fact, the statistics concerning alopecia are actually quite alarming.

40% of American men experience hair loss by the age of 45, while 65% encounter this problem by age 60 and by age 85, a whopping 80% of American men will have nothing left to comb over. They can’t all be wearing headsets.

There are, however, some things that are proven to cause both hair loss and baldness. The following things can cause hair loss:

  • Stress.
  • Hormonal issues like hypo-thyroidism.
  • The side effects of certain medications.
  • Wearing tight hairstyles like pigtails or cornrows.
  • Some chemicals found in various hair products (e.g. permanents or relaxers).
  • Fungal infections.

To date, we don’t think anyone has ever gone bald from wearing headphones (although we certainly wouldn’t rule out the possibility that many a balding person has blamed it on them!)

If you are worried about losing your hair, a good piece of advice is to look at your grandfather. Why? Well, before we sign off, here is a final piece from Health Central.

“According to an article in ScienceDaily, the gene that is sometimes responsible for male baldness is inherited from the mother because this particular gene is found on the X chromosome. For men whose fathers became bald, this could be good news. It seems you should look to your grandfather, on your mother’s side, to find out if you have a higher risk of baldness due to genetics”.

Photographic Find of the Century Depicts Trench Life in WW1

Although it meant disobeying direct orders (and a court martial if he was discovered), Lance Corporal George Hackney obviously felt a duty to document The Great War from a soldier’s perspective. Now, to commemorate the centenary of the First World War, his incredible photographs are being displayed in public for the first time.

The astounding collection, which includes candid photographs taken in the British trenches – and at least one amazing shot of a German surrender in 1916, was compiled between 1915, when Hackney was first sent to the front lines, and 1918, when the brutal conflict finally ended, and the photographer returned home.

Before he was called up, Hackney was a keen amateur photographer, and it shows. His pictures demonstrate a very accomplished sense of composition, but never feel forced or especially posed for (as some photography from the era can). In fact, the images are easily among the most intimate and credible pictures that exist from the conflict.

Among the most remarkable shots is a poignant image of a lone soldier writing a letter home, as well as another showing a group of soldiers (in full uniform) casually napping on the deck of the ship that would eventually deliver them to the front lines.

At the time these photographs were taken, no unofficial photography was allowed on the front lines. However, using a portable folding camera about the size of a modern smart phone, the Northern Irishman was able to document the war effort discreetly and respectfully.

Hackney then gave the photographs to his own family upon his return. In addition, many of his pictures were given as gifts to the families of the men photographed, sometimes offering grieving loved ones a chance to see their missing husband, brother or son, one final time.

To cite one such example, Hackney’s Sergeant, James Scott, was killed at the Battle of Messines in May 1917. After Lance Corporal Hackney returned home, he presented Scott’s family with three pictures of him, including a striking depiction of the officer looking proud and dashing on horseback.

The Sergeant’s descendant, Mark Scott, was instrumental in uncovering the stories behind these wonderful, and often profound, images…

Hackney’s pictures also provide excellent accompaniment to the war records of the men in question, rendering them as much more than simply names and numbers, or even as symbols of pure courage and sacrifice. Hackney’s photographs present these remarkable men to a new generation as simple Human beings fighting through an incredibly difficult time to be alive.

A photograph taken at County Antrim, which depicts Hackney’s friend John Ewing writing a diary entry (or possibly a letter home), adds a Human element to the historical facts that Ewing was eventually promoted to Sergeant and subsequently won the Military Medal for bravery in the field…

Stories like this abound in Hackney’s work, which ably presents the war in a far more evocative way than the official press photographs and propaganda of the time could ever have hoped to.

When George Hackney passed away in 1977, his family donated the pictures to the Ulster Museum, where they stayed in the Museum’s archives for over 30 years. These unique, powerful documents were, in turn presented to TV Director Brian Henry Martin by museum curator Dr. Vivienne Pollock, in 2012. Martin was shown the images alongside a collection of Hackney’s personal diaries and was captivated by them.

Lance Corporal Hackney eventually became the subject of a BBC Documentary, directed by Martin, entitled, ‘The Man Who Shot The Great War’. The show aired in Northern Ireland earlier this month.

In addition, Hackney’s work is soon to be the subject of a major exhibition at the Ulster Museum.

Mr. Martin is now bringing 300 of Hackney’s images to the BBC for future use, although it is estimated that there are around 200 more that are undiscovered at the time of writing.

Amanda Moreno of the Museums of The Royal Irish Regiment, told Yahoo! News that, “As a collection of photographs of the First World War, they are totally exceptional.”

Interviewed for the film, Franky Bostyn, Chief of The Belgian Ministry of Defense said, “I think you made the photographical World War One discovery of the century.”

100 years on, George Hackney’s unique, vivid and (above all) brave photography presents us with a deeply Human portrait of life in the trenches of The Great War.

Introducing the Sensear Intrinsically Safe Double Protection Headset

Many of you might not heard of Sensear, they are making big strides in the headset industry, here is their latest offering.

Sensear, a global leader in developing and manufacturing best-in-class digital communication headsets, announced the release today of their new Intrinsically Safe Double Protection Headset (IS-SDP). Based on Sensear’s existing SM1xSR IS headset, and incorporating the double protection feature from Sensear’s current non-IS double protection headset; the new IS-SDP headset includes an improved boom microphone, and will interface with a variety of two-way radios both cabled and via Bluetooth for wireless operations.  Bluetooth can also be used with IS Smart phones and other IS Bluetooth devices.

The Sensear IS-SDP headset was developed from a marketplace need for a high performance intrinsically safe headset for extreme noise environments that require Class 1 Div 1 certification. Double hearing protection (both ear plugs and ear muffs) is often required when exposures may exceed 95 decibels (dBA) in many critical working areas. At the same time operators in these environments are required to use two-way radios to hear site communications and respond appropriately. Without the use of an appropriate intrinsically safe headset communications on site can potentially be very difficult.

The ear-plugs for the IS-SDP are hard wired to the headset allowing for dual protection, and communications to be directly understood by the operator. The IS-SDP’s 31 dB NRR combined with Sensear’s patented SENS™ technology allow operators to protect their hearing at a safe level of 82 dB, communicate effectively between co-workers via two-way radio and Bluetooth and maintain 360-degree awareness.

“We were excited about the development of the IS-SDP the early beginnings of Sensear grew from creating unique solutions for many industrial environments,” said Peter Larsson, CEO.  “The IS-SDP continues to show our commitment to developing practical, usable products that solve the communication challenges in heavy industry.”

Security Earpiece For the iPhone

With every passing day, technology is improving and it has made lives of people easier and better in many ways. Some of the latest technologies and gadgets have really been helpful to many people. If you look at the security earpiece then you will understand how advantageous it is for specific people. There are different types of these earpieces available and you can also get these for your iPhone. You just have to check whether or not these are suitable and compatible with your handset.

Use Of Security Earpieces

These earpieces are only required when you want to communicate with someone secretly. The security earpiece is fitted into the ears and normally people around you cannot see it. It is small and is connected by a very thin wire. Security personnel mainly use these types of earpieces. But people also use this when they are in a conference and want to communicate or hear something while communicating. You can also find it useful in movie sets, broadcasting of radios etc. Even it will be great for using inside classrooms and not getting caught by teachers!

This is quite small in size the voice transmitted via this cannot be heard outside. Only the person who is wearing it can hear the voice. Thus, you can secretly converse with someone while none will even know about it. In case of audio surveillance, security guards and bodyguards use this earpiece to make sure they can hear each and everything distinctly. When a person is speaking on radio in front of a microphone, he/she has to make sure that even a message comes through the earphone it is not heard outside. So, with the help of the security earpiece it is very much possible.

Connecting To Mobile

Though these earpieces are meant mainly for security purposes, many people find it cool! They use this as a style statement and wear it just for fun. It has become a part of cool accessories which many enthusiasts prefer to use while going out. It is not necessary that you have to be a spy, bodyguard or a secret agent in order to buy or use this. You can simply buy one security earpiece for your iPhone too. it also comes with a separate mouthpiece which you can put on anywhere you feel comfortable.

If you are an owner of an iPhone then you can get the security earpiece for your particular handset. The jack which will be connected to your earphone port of the mobile has to be compatible to each other, normally a 3.5mm Jack. If not then you will not be able to hear or listen to anything. This is very much important. So, it is best to buy the security earphones specially made for each model of iPhone. With the help of this you can talk over phone while driving or even you can hear songs and watch movies.

Some Useful Tips

Since you have to wear these earpieces inside your ears, you have to be much more conscious of it. Make sure that you are not allergic to the material by which earpiece is made up of. If you are then avoid using that material as it can be harmful for you. The earpiece is fitted inside the ear exactly beside your eardrum. While wearing it you have to be careful about whether or not the earpiece is touching your eardrum. If it is not touching then you will not be able to hear anything or you will hear a low voice. When you are done you have to take out that earpiece as well. In this case also you have to be very much careful.

Your ear, mainly eardrum, is very much sensitive. You have to make sure that the security earpiece you are buying for your ears is not made up of some low quality material. It can react badly with your inner ear skin. So, when you are buying one for your iPhone, you have to choose the best one made up of high quality material. These are mainly available in rubber and thus you have to confirm that you are not allergic to it. This is surely a great technology and a cool accessorise for the one who want to use it just for fun for their iPhone.

How to be a better headphone listener

When you’re listening to speakers the sound comes from “over there,” but with headphones where is the sound? A lot depends on the recording and the headphones. With mono recordings the sound is centered inside your head, with stereo the sound picture is more complicated. Vocals, or any sound mixed to appear centered between the left and right channels, will be inside your head, like a mono recording. The sounds over to the left and right might come from next to your ears.

Listening over one of the better open-back full-size headphones, the sound might feel like it’s surrounding you. You’re in the middle of the sound field, or it might come from slightly above your head. The headphones melt away and you are one with the music. Sometimes when I’m watching a movie I forget the headphones. The sound isn’t over there, it’s all around me; I’m in the middle of a sound “bubble.”

I’m not suggesting that headphones can ever mimic what we hear from speakers. Headphones can’t do that, but the downside to speakers is they can never be heard directly; the speakers’ sound is combined with the room’s reflections, reverberations, and other forms of acoustic interference. With headphones the sound “couples” directly to your ears, so you have a far more intimate connection to the music.

With full-size over-the-ear headphones, the contours of your outer ears direct the sound to your inner ears in the same way sound is heard from speakers. In-ear headphones “bypass” the outer ear and produce a more direct connection to the recording. With purely acoustic music, the sound over headphones takes on what I call a microphone perspective, you hear what the mics “heard.”

That’s not the case with electronic music since no microphones were used to make the recording. Even so, I find lots of electronica sounds amazing, and some of the best albums were mixed to produce out-of-head stereo imaging. Listen for depth, does the sound seem very close to your ears or further away? Recordings vary a lot in their stereo imaging, but the more closely you listen, the more aware you will be of spatial cues in headphone listening. Try some of Brian Eno’s ambient albums like “On Land” and “Apollo” to hear what I’m talking about.

To get started, relax and focus on the sound. Your surroundings should be fairly quiet, close your eyes, and sink into the music. After a few minutes the separate left, center, right stereo perspectives should fall away, and your head will feel like it’s in the center of an expansive sound field.

Share your thoughts on spatial headphone listening below.

We found this excellent article here and as you can see it give us valuable information on why headphones aren’t better than speakers, but if you don’t want your neighbors complaining or your family moaning, then you’ll have to wait for the technology to come up with perfect acoustic sound.

How a Digital Walkie Talkie Works?

The Digital Walkie Talkie is the best way to communicate other than cellular phones on the world market. These devices are still widely used by the military personal, police officers, public event organizers, etc.

You might be quite interested how the digital Walkie Talkie Works? A walkie-talkie is a hand-held portable radio which communicates wirelessly using the radio wave signals on single and shared frequency bands.

Each of the battery-powered units of the device contains an antenna and transmitter/receiver for sending and receiving of the radio waves. It also contains a loudspeaker that doubles up as loud as a microphone when someone talks into it. There is also a “push-to-talk” or PTT button for this purpose.

The loudspeaker/microphone of the device works following the same mechanism as that of the intercom. The microphone and speaker contains almost the same components viz. a magnet, a wire coil, and a plastic or paper cone to pick up and generate the sounds.

You can also use any single device to do both jobs by switching electrical circuit and reversing the current flow. Walkie talkies manufactured by big companies include separate microphones and loudspeakers. Thus, it is based on a very simple mechanism.

How to use the Walkie talkie?

Groups of People who talk on the digital Walkie Talkie don’t need to tune into the same frequency band. Thus the Digital element of the Walkie Talkie. The radios of these walkie talkies are all receiving. Thus, the microphone/loudspeaker units work as a conventional radio.

If you want to talk with others via a walkie talkie, then you need to hold the push-to-talk button on the handset. After that, the radio becomes quiet as the loudspeaker switches over to the microphone.

As you talk into it, your words are converted into the radio waves and are then beamed out on a prearranged channel. Typical frequency of this channel is around 400 MHz. The radio waves are a part of the electromagnetic spectrum, they travel at the speed of sound.

The high-speed sound waves are very easily picked up by the other handsets. The radio waves are converted back into electric currents and are used by the loudspeakers to reproduce the sound of the voice of the person who is talking.

When the talking is finished, the talker says “over” and releases the “push-to-talk” button.

The radio now switches back into listening mode and someone else can talk. After this, the radio switches back into the listening mode.

The most distinct feature of the digital Walkie Talkie that makes it quite different from the normal radio is that it is a 2 way radio that is you can talk as well listen with the help of this device.

What are the benefits of using these devices?

The digital Walkie Talkie is a simple, robust and easy to use device for indoor as well outdoors. These devices are also very much suitable for the children as these are very light and easy to carry and handle.

The kids can keep in constant touch with their parents with the help of these devices. These are very much suitable for the business application purposes.

What are the major specifications?

A Digital Walkie Talkie is very convenient and weighs 100-200 grams and can work over a 5 to 10 square kilometer or 2-4 square miles. These electronic devices also have a very long battery-life of almost 20 hours.

The Walkie-talkies have multiple channels. So you can easily switch from one to the other easily. Some walkie talkies also have baby monitor intercoms.

What are the various parts of this device?

Variois parts of the digital Walkie Talkie include antenna, LCD displays, select buttons, monitor, menu buttons, loudspeaker, PTT button, volume control, on/off switch, microphone, LED indicators, etc.

The radio waves are sent and received by the antenna. The LCD display shows the channel number, battery life, etc., baby monitors are sometimes fitted within the device, the menu buttons are used to change the settings and functions of the device.
