a musical instrument that converts sound waves into an electrical up-to-date, typically fed into an amplifier, a recorder, or a broadcast transmitter.
a tool (transducer) accustomed convert sound waves into a varying electric current; usually fed into an amplifier and either taped or transmitted.
An instrument for converting sounds into electric signals, for the true purpose of recording or amplifying the noises. It creates its impacts in various means, in terms of example because of the modifications of power in a power up-to-date, occasioned by the variants within the contact resistance of performing figures, specifically of imperfect conductors, in activity of acoustic oscillations. Other types of microphone might use changes in capacitance or any other phenomena to transduce the noises into electrical indicators.
