A picture of a microphone.

A microphone is an electrical device that turns the vibration of a sound into an electrical signal.

Sound transfers information which a microphone converts into an electrical signal.

Microphones use a coil of wire and a permanent magnet to turn a vibration into an electrical signal.

When the receiver vibrates the coil of wire moves around the permanent magnet to make a current in the coil of wire.

A microphone is an electrical device that turns the vibration of a sound into an electrical signal using the generator effect.

Sound transfers information which a microphone converts into an electrical signal.

Microphones use a coil of wire and a permanent magnet to induce a current in the coil when receiver vibrates.

When the receiver vibrates the coil of wire moves around the permanent magnet to make a current in the coil of wire.
