A microphone is "an instrument capable of transforming sound waves into changes in electric currents or voltage, used in recording or transmitting sound."

Basically, it records, detects, or magnifies voice or sound.
A microphone converts the pressure waves caused by sound into vibrations within a coil which transforms the vibrations into electric signals. These electric signals can then be sent by wire or wireless to an amp or mixer of some sort for output to speakers or perhaps a recording device.
