Earphone: how does it work and how to use it?

Earphones occupy a special position among the devices of the wireless type of covert information transmission. From the material in this article, you will learn what it is, how it works and how it works, what happens and how to choose the best option correctly.

The earpiece belongs to wireless microdevicesthat are inserted into the ear canals. It is used for discreet transmission of speech or other sound signals... It is not seen by others, it differs in a special way of insertion into the ear canal.

This is a capsule smaller than a regular coin, characterized by full compatibility. The earpiece works with any device for playing and transmitting an audio signal at a certain distance. Such gadgets are synchronized with walkie-talkies, players, mobile phones, dictaphones.

Micro-headphones work on the principle of electromagnetic induction. Therefore, they are often called induction.

In addition to the device itself, the package for covert communication between interlocutors includes mobile phone (walkie-talkie) and headset. The connection between the microscopic earpiece and the headset is ensured by magnetic waves... Their source is induction loop antennawhich consists of twisted insulated copper wire. The power of the electromagnetic pulse depends on the number of turns and the diameter of the loop. The higher they are, the greater the range. Earpiece speaker, similar to a microscopic cylinder, has no wires. Its optimal dimensions are 2x2 mm.

The work of the earpiece is based on the work of a special device, which is connected to the telephone jack at the point of contact with the traditional headset. Once on the phone, the signal goes to the antenna. It is transformed into a magnetic field, vibrations affect the ear membrane. A person perceives them as a certain sound signal.

This sound can only be heard by someone with a speaker inserted in their ear.... Nearby people will not be able to recognize, hear the sound, or see the inserted device. The earpiece is powered by a microscopic battery, and the contact is established via a Bluetooth connection. The distance between the phone and the transmitter can be up to 10m.

The wireless earphone is simple and easy to use. The transmitter loop with a built-in high-sensitivity microphone is worn around the neck and hidden under clothing. The design of the in-ear device is made of a metal alloy with magnetic properties.

Based on the type of signal conversion, microscopic headphones are capsule and magnetic... They are fundamentally different, each type has its own differences and characteristics.

Wireless devices of this type are distinguished by their smallest dimensions, which are usually less than 5 mm... Thanks to this, you can not be afraid that someone will find them at the most inopportune moment. They are thrown onto the eardrum itself.By design, they are primitively simple and do not have any electronic filling. They are in the form of a tablet, weighing no more than 1 gram.

However, these devices have a lot of disadvantages.

1. The key one is contact with the membrane... It is harmful and dangerous for health, people with ear diseases cannot use this technique.
2. In comparison with capsule counterparts, these devices are quieter. But this is enough to hear the interlocutor.

Their advantages include the fact that they do not need to constantly change batteries.

Magnetic earpieces need to be able to fit correctly in the ears... Otherwise, there is no contact and sound. Products of this type can let the user down. At the moment of communication, the speaker may move away from the eardrum, causing the sound to disappear. To return it to its place, you have to shake your head.

Products of this type are cylindrical and look like ordinary earbuds... However, the shape itself for models from different companies may vary, so the price of the device is also different. The housing contains the receiver and the transducer. The power supply, amplifier, speaker are also located here.

These products versatile and compatible with any headset. The smaller their size, the more expensive they are. Nano headphones are the smallest representatives of this species. In general, the use of devices does not differ from traditional counterparts. Therefore, capsule earpieces are inserted into the ear in the same way.

They have no contact with the eardrum, although they go into the ear to different depths. However, these models are safer, they do not get stuck in the ears and are stable in operation. The sound will not disappear in them, regardless of the position of the head and the movements of the user. In this case, the signal is clearer and louder.

The disadvantage is the likelihood of breakage. in case of rough handling, as well as the visibility of individual models.

If you wish, it will not be difficult to make out such a capsule. Its length can vary from 5 to 10 mm, and in some cases it reaches 13 mm. At the same time, large devices are inconvenient to use. Besides the size, they differ in color, wide range of models, safety and durability.

Today, manufacturers of earpieces produce a wide variety of device modelscapable of satisfying the needs of even the most discerning buyers. If desired, you can purchase not only classical inductive varieties, but also options with camera, and microscopic headphones that no one but a doctor will see.

But despite the widest choice, you need to buy the best option taking into account the knowledge of some factors. For example, magnetic devices win in size, however, they cannot be called completely safe for health. They cannot be worn more than the time stated in the characteristics. It is also bad that when using them, discomfort may arise.

If you compare according to the likelihood of breakage, magnetic varieties are better... However, they can be washed.

Capsule counterparts are good because they work great even in a noisy room. However, their sound can be heard in a quiet room. They cannot be used during an exam or other cases when a hidden connection is required. The shape of capsules with electronic filling, in addition to being cylindrical, can be conical. Some varieties resemble a parallelepiped. It is more convenient to insert them into the ears, they are considered more reliable.

The case of many capsule models is made in beige or light brown. A distinctive feature of domestic and Chinese products is the black color of the cover, under which the batteries are hidden.

Kind of work capsule and magnetic products vary. When choosing them, it is necessary to take into account headset type... If you wish, you can choose options not only of the classic type, but also products disguised as familiar accessories (glasses, pens, watches). You also need to select the type of earphone for the headset. Magnetic earbuds (especially the budget type) can be connected to the headset with an additional battery, which will amplify the incoming signal.

The choice of the best product depends on your own preferences. In this case, one has to choose between safety and work.

Choosing one or another option, you can take a closer look at voice control products and the ability to use one earphone... They are autonomous, have a low price and sound volume control. They work at a distance of up to 10 m, and are connected to the phone via a Bluetooth module.

When buying, you need to check purity and loudness of sound, evaluate the build quality, choose the optimal size... In addition, the check will allow you to understand if the sound is coming in correctly or with a delay.

Capsules differ not only in size, but also in the volume of the incoming sound. In addition, they are variable in price: the cheapest options are not visible from a distance of 1.5 m. Those that are inserted deeper into the ear are not visible from a distance of half a meter.

Miniature models that go into the turn of the ear canal, not visible at close range. If you want to buy nano-headphones, you should choose the options in the form of balls... They are easier to place in the ear canal and have better sound. Products of this type can be removed from the ears without painful sensations. You need to take that complex (earpiece with a headset), the principle of interaction of which seems more convenient for a particular person.

It is important to pay attention to the dimensions. Manufacturers often indicate their data that differ from real values. The characteristics indicate a lower value (about 3 mm less). This is due to the fact that the size of the earpiece is measured along the length of the speaker, excluding the thickness of the battery.

Each type of product has its own warranty. Each manufacturer has its own. For example, German brands offer a 36 month warranty. Brands of Russia and China give less guarantee - from six months to a year.

Use earpieces correctly... For example, the capsule model must be inserted into the ear with two fingers. They are removed using a fishing line. Nano-analogs of the modern type of miniature size can be inserted in the same way. In order to get them, you need a special magnet. After purchase, the user will need an assistant who can dictate some information. It is necessary to connect the device using the instructions supplied with it. Before inserting the capsule-type micro-earpiece into the ear, a battery is placed in the slot. The scheme consists of several sequential steps.

1. The induction loop should be put on the neck and hidden under the clothes behind the back.
2. If there is no wired connection to the phone, you need to connect Bluetooth to it.
3. Silent mode is activated on the smartphone and the call is automatically answered.
4. After that, you need to take out the earpiece and insert it into your ear.

When using a capsule device it is inserted into the ear canal, after which it is supplied with power to the loop antenna. It is connected to a smartphone via a connector, then the quality of the connection is checked. To do this, call the interlocutor or turn on the music. All that remains is to adjust the volume - and the device can be used.During operation, there is a decrease in the quality of the incoming sound signal. The sound is poorly heard when the earpiece of the device is covered with earwax. Also, the reason may lie in a low battery level. If the music is heard well, but the interlocutor is bad, this indicates a microphone malfunction.

In order not to compromise the sound quality, the microphone loop should be located as close to the receiver as possible (preferably around the neck). If it is twisted or placed in a pocket, the device may malfunction.

You need to use the device correctly. Do not insert it into an ear canal that is clogged with wax. If it is not needed, it is necessary to remove the batteries from it. They are also removed from the antenna. The batteries are changed as needed.

Magnetic earbuds are placed in the ears using a plastic tube. Before that, the ears are cleaned, otherwise the magnet extractor will not be able to pull the earphone out of the ear. And then the doctor will have to solve the problem. To understand if the device is working correctly, you need to immediately turn on any music on your smartphone. If sound comes in, the placement is correct. You need to insert the earpiece while sitting. In this case, it should be placed in the ear canal for two-thirds of the tube used.

To avoid injury to the ear, insert the device slowly and smoothly... This may cause a sensation similar to water getting into the ears. As soon as the tube is inserted into your ear, you need to tilt your head to one side. This will lower the magnet to the desired depth. You can wear it for no more than 2 hours, after which you must remove it. To do this, use a special stick with a magnetic tip.
