Contact microphones based on piezoelectric materials are passive and high-impedance, and they sound tinny without a matching preamp. Instead of being used as a microphone, they alternatively may be used to produce sound (typical used as the buzzer in computer motherboards ) by sending voltages to them.
ORTF setup. The ORTF stereo technique, also known as side-other-side, is a microphone technique used to record stereo sound.It was devised around 1960 at the now-defunct Office de Radiodiffusion Télévision Française (ORTF).
In the middle of the cavity was a mushroom-shaped flat-faced tuning post, with its top adjustable to make it possible to set the membrane-post distance; the membrane and the post formed a variable capacitor acting as a condenser microphone and providing amplitude modulation (AM), with parasitic frequency modulation (FM) for the re-radiated ...
Shure Brothers microphone, model 55S, multi-impedance "Small Unidyne" dynamic from 1951. A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal.
Parabolic microphone used at an American college football game. A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna (e.g. satellite dish) does with radio waves. Though they lack high fidelity, parabolic microphones have great ...
