[M] are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers and other electronic devices, such as mobile phones, for recording sounds, speech recognition, VoIP, and other purposes, such as ultrasonic sensors or knock sensors.

The most common are the dynamic [M] , which uses a coil of wire suspended in a magnetic field; the condenser [M] , which uses the vibrating diaphragm as a capacitor plate; and the contact [M] , which uses a crystal of piezoelectric material. [M] typically need to be connected to a preamplifier before the signal can be recorded or reproduced....")
