Explanation:

A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. ... In a condenser microphone, the incoming sound vibrates one plate of a capacitor. The varying capacitance is converted into a corresponding electrical signal.
