n. A device (transducer) used to convert sound waves into a varying electric current; normally fed into an amplifier and either recorded or broadcast.

v. To put one or more microphones on or in.

n. An instrument for converting sounds into electrical signals, for the purpose of recording or amplifying the sounds. It produces its effects in various ways, as for example by the changes of intensity in an electric current, occasioned by the variations in the contact resistance of conducting bodies, especially of imperfect conductors, under the action of acoustic vibrations. Other forms of microphone may use changes in capacitance or other phenomena to transduce the sounds into electrical signals.

n. An instrument for augmenting Small sounds.

n. device for converting sound waves into electrical energy
