Condenser Microphone

Condenser Microphone: In a condenser microphone, a capacitor is used to sense changes in the distance between two metal plates as the vibrations from a sound source hit them. The changes in distance are measured by the minute fluctuation of an almost constant electric current running between the two metal plates. Since the capacitor requires an electric charge, condenser microphones require a power source, either from batteries or phantom power supplied by an audio jack. [ Audio Glossary ]
