The lavalier microphone (or "loop") mimics standard microphones in its functional characteristics, however, it has several unique features. The main task of a lavalier microphone is to eliminate extraneous noise during sound recording. The equipment is so called because it has a peculiar shape and is attached to clothing.

A lavalier microphone is a popular and sought-after device that is used by a large number of users (for example, journalists in the process of getting interviews, video bloggers filming videos on Youtube, etc.).

At the same time, there are certain disadvantages of using such a device. For example, clothes rustling as well as chest vibrations can cause interference. In addition, the lavalier microphone itself is limited, which is a significant obstacle to the use of the device. In order to eliminate the existing shortcomings, manufacturers are constantly working on improving technology. So, some companies have built in filters in microphones to help remove background noise.

The principle of operation of most lavalier microphones is based on the characteristics of an electrical capacitor (the only exceptions are dynamic models). Thus, the sound waves received by the microphone cause vibrations of the membrane, which is elastic in its parameters. In this regard, the volume of the capacitor changes, an electric charge appears.

There are many types of clip-on microphones. They are classified according to a variety of characteristics and properties.

Today in our material we will consider several popular types of buttonholes.

• Wired... The wire lapel is used in cases where there is no need for constant movement.
