Background

A microphone, known as a microphone, is an energy conversion device that converts a sound signal into an electrical signal. Also called microphone, microphone. In the twentieth century, microphones were developed from the initial sound-electricity conversion by resistance to the inductance-capacitance conversion, and a great number of new microphone technologies were developed, including aluminum strip, moving coil, etc., as well as condenser microphones and electret microphones which are widely used at present.

The wireless microphone is divided into three frequency bands, namely an FM band, a VHF band and a UHF band. The FM wireless microphone has the advantages that: the circuit has simple structure and low cost, is beneficial to the production of manufacturers, and has the following defects: the tone quality is poor, the frequency can change along with the change of time and environmental temperature, the situations of poor reception and signal interruption can often occur, and the interference is large. The loud call facing to the microphone will have sound break, and the use occasion is as follows: the use requirement is low, and the requirement on the tone quality is not great. In this case, only sound is required, and an FM wireless microphone can be selected. The VHF section is commonly referred to as V section, and the frequency is between 180 and 280 MHz. Because the frequency is higher, generally receive the interference very little, adopt the crystal to lock the frequency, the condition of frequency conversion can not appear, and reception performance is comparatively stable. The V-band wireless microphone generally has two circuits, namely a first circuit; the high frequency part is integrated with only one 2003 IC. Including the following. Signal receiving, radio frequency amplification, frequency mixing, frequency discrimination and the like are completed in one step. The sensitivity is not high, and the 31101 circuit is adopted in the frequency part. The audio is compressed and expanded, and the sound quality is greatly improved compared with FM. The receiving performance is improved by one grade. The UHF section is commonly called as U section. The frequency is typically 700 and 900 MHz. Such high frequencies are substantially free of other extraneous frequencies that could interfere, and patch elements are used in most of the U-section. The performance is very stable, and there are three circuits for U to do. The audio frequency gain circuit adopts the latest 571 lines, so that the sound quality is better. The sound field changing function of the existing microphone is mostly arranged on a loudspeaker host machine, and the existing microphone does not have the sound field changing function, so that the existing microphone does not have the sound field changing function when different loudspeaker host machines are connected.
