What Is the Principle of the Condenser Microphone?

- May 08, 2018-

The principle of the condenser microphone: Use a very thin metal diaphragm as the first level of the capacitor, and another very close metal backplane (a few tenths of a millimeter) as the other pole, so that the vibration of the diaphragm will cause the capacity of the capacitor. The changes form electrical signals.

The advantage of a condenser microphone: Since the diaphragm is very thin, it can be made to vibrate with very small sounds, so the condenser microphone is very sensitive.
