A throat microphone, also called a laryngophone, is a type of contact microphone that absorbs vibrations directly from the wearer's throat by way of single or dual sensors worn against the neck. The sensors, called transducers , can pick up speech even in extremely noisy or windy environments, such as on a motorcycle or in a nightclub .
On 25 August 2009, U.S. patent 7,580,533 was issued for a device that uses a laser beam and smoke or vapor to detect sound vibrations in free air ("Particulate Flow Detection Microphone based on a laser-photocell pair with a moving stream of smoke or vapor in the laser beam's path"). Sound pressure waves cause disturbances in the smoke that in ...
A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal. Microphones 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 ...
Two pins are used for the mono headphone signal and two pins for the unbalanced microphone signal. The 4-pin XLR connector is also commonly used on amateur radio microphones, but transferring unbalanced audio instead, and using the 4th pin (with the common ground) for a push-to-talk (PTT) circuit activated by a button on the microphone.
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 sensitivity to sounds coming from one direction, along the axis of ...
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.
A contact microphone is a form of microphone that senses audio vibrations through contact with solid objects. [1] Unlike normal air microphones, contact microphones are almost completely insensitive to air vibrations but transduce only structure-borne sound.
The boundary microphone can be used as a piano mic by placing it inside the piano lid, an approach which can obtain better pickup of the piano's mix of sharp percussive transients and gentle undertones than other microphone options. Boundary mics are used on hockey boards for body check sound effects. They are also commonly used to record full ...
