Magnetic earpieces: characteristics, pros and cons, rules of use

Earphones are simply an indispensable accessory that will help you reproduce the information you need. And also hidden headphones will become the best assistant for exams or lectures. The assortment of such devices is so great that eyes widen. Let's take a closer look at what they are, what impact they have.

The invention was originally intended for people with hearing impairments. But over time, the scope of use has become much wider. This type of headphone is very small. Their design consists of several elements: microdynamics, headsets with a signal amplifier, antenna, microphone, battery. Magnetic waves are used to transmit information.

The device can be operated only with the use of an induction antenna, which is attached to the neck. Thanks to her, the vibrations perceived by our ear go. The device itself connects to a mobile phone and microphone.

If you need to get information on headphones, you just need to call a friend and he will dictate everything to you. The built-in speaker in the device is made of a special alloy and has magnetic properties. It works without recharge, looks like a flat tablet. The connecting link between the telephone and the antenna is the microphone. With the help of the antenna, the signal from the mobile device goes to the magnet in the ear.

Such a small device is placed in the ear using a special tube.... The work of such headphones is based on the use of magnetic induction. An electric current passes through the induction circuit, the magnetic field is excited and propagates in space. The earpiece receives electromagnetic waves, and with the help of a magnet they are transformed into sound waves. There are two types of miniature headphones: magnetic and capsule. Capsule types are battery operated with which they are supplied. In the magnetic versions, the set includes a magnetic holder and a clamping holder. In both versions, the headset can be connected to the phone by wire or via Bluetooth.

These devices have their pros and cons. Of the advantages, one can note a fairly affordable cost compared to other devices for transmitting information. They are very convenient to use as they are suitable for any conditions. The design is quite simple and does not lend itself to deformation and breakage. Due to their small size it is very difficult to detect them, they are an indispensable device for supplying hidden information. Among the advantages, one can also note the purity of the transmitted sound, which goes directly to the auditory canal. The device allows you to communicate with your opponent even at a distance of several meters.

Of the shortcomings, it can be noted some difficulty in placing the device in the eardrum, sometimes it causes discomfort. Another disadvantage is the short battery life. This is possible within 4-5 hours. Also, it is difficult to remove the device from the auricle: for this you need to use a special magnetic stick.

If we consider the use of a capsule version with a built-in battery, then this option must be inserted into the ear to such a depth that no one can detect the device. In order not to risk and install at a shallow depth, the use of this type of headphones is recommended for people with long hair.

As for the installation of a magnetic earpiece, everything is more complicated there. There is no attachment, so you have to use a special stick with a clip. The earpiece is attached to the stick, and the head is tilted with the ear up. The earbud is lowered as deep as possible into the sink. Here you need to be careful not to damage the membrane. After installation, you first hear a click, and then there is a slight congestion in the ears, which passes over time.

You can wear headphones for no more than two hours, as this may affect your hearing... Headphones are an individual thing, so they should not be given to other people to wear, as there is a possibility of spread and infection by microbes. Children under the age of 12 should not wear headphones as magnetic models can have a negative impact on the development of children's hearing. If magnetic headphones are used by several people at the same time, they should be kept as far apart as possible, as magnetic fields cause interference.

Connecting headphones is pretty simple. To do this, the plug is connected to the headset jack of the phone, the antenna is put on the neck, a connection is established between the headset and the mobile phone, the speaker volume is adjusted. After that, the earpieces can be comfortably used during the exam or any lecture. Devices are ideal for speaking in front of a large audience, where you have to speak a lot, and reading from a leaf is completely indecent. Intelligence officers always use such models. Lovers of gambling often play dishonest games with their help.
