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.
An electret film is applied to the back plate of the microphone capsule and the diaphragm is made of an uncharged material, which may be mechanically more suitable for the transducer design being realized. Front electret This design features no back plate, and the capacitor is formed by the diaphragm and the inside surface of the capsule.
In the early 1930s, the BBC became aware of RCA's model 44 ribbon microphone that was used in Hollywood. [1] [6] Each pair of microphone and amplifier would have cost the BBC £130 (approximately £6,500 in 2009. because of inflation) [6] [7]). As this was not within the BBC's budget, they designed their own microphone, the Type A, alongside ...
Shure SM7B microphone used in an interview with Marius Bear The Shure SM7 is a professional cardioid dynamic microphone , commonly used in broadcasting applications since 1973. Designed by Shure , it has been described as an "iconic" industry standard microphone for its focused, directional sound and its widespread adoption in radio, television ...
Carbon microphone from Western Electric telephone handset, around 1976. A disassembled Ericsson carbon microphone with carbon particles visible. The carbon microphone, also known as carbon button microphone, button microphone, or carbon transmitter, is a type of microphone, a transducer that converts sound to an electrical audio signal.
The large size and weight of the RE20 requires a strong microphone stand or boom arm, and a very sturdy microphone clip or robust hanging yoke. The supplied mic clip (model number 320) is tightened securely with a knurled knob. An optional shock-mount is available for the RE20 family of microphones: the EV model 309A.
The RE series used "Variable D" technology first developed by EV in 1953, which eliminated changes in tone and frequency response corresponding to changes in the physical distance of the sound source from the microphone. [1] [4] The RE20 broadcast microphone was introduced in 1968, followed by the RE27N/D in the late 1980s, using neodymium ...
A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds ...
