A microphone, colloquially nicknamed mic or mike (/ËmaÉªk/), is a transducer that converts sound into an electrical signal.
In a condenser microphone, the diaphragm is mounted close to, but not touching, a rigid backplate. (The plate may or may not have holes in it.) A battery is connected to both pieces of metal, which produces an electrical potential, or charge, between them.
