Know About Wireless Microphone
What is the sound principle of microphone
The microphone transmits the sound vibration to the diaphragm of the microphone and pushes the magnet inside to form a changing current. In this way, the changing current is sent to the rear sound processing circuit for amplification.
Sound is a wonderful thing. The different sounds we hear are produced by the small pressure difference of the air around us. The wonder is that air can transmit these pressure differences so well and truly over a considerable distance.
