The principle of microphone

The principle of a microphone is that the vibration of sound is transmitted to the diaphragm of the microphone, which drives the internal magnet to form a changing current. Then, this changing current is sent to the sound processing circuit for amplification processing. A microphone, scientifically known as a microphone, is an energy conversion device that converts sound signals into electrical signals. The official Chinese name is microphone, also known as microphone or microphone. Its working principle is to use a polymer material diaphragm with permanent charge isolation. Most microphones are polarized condenser microphones.
