A microphone that uses a thin electrically conductive ribbon between the poles of a magnet to produce a voltage by electromagnetic induction.

(electronics, especially aviation) A microphone that is activated (but not powered) by the sound of the user's voice, allowing it to pick up speech without having to be manually turned on, while still rejecting background noise unaccompanied by speech.

(film, television, sound engineering) A highly directional microphone for capturing only the sound directly in front of them, often used at a distance.

(sound engineering) A small, hands-free microphone which is worn attached to the body or clothes.
