1680s, "ear trumpet for the hard-of-hearing," coined from Greek mikros "small" (see mica) + phone "sound," from PIE root *bha- (2) "to speak, tell, say" (see fa [..]

Devices that convert acoustical sound waves into corresponding variations in electrical current that are then amplified, transmitted, or recorded.

device for converting sound waves into electrical energy A microphone (colloquially called a mic or mike; both pronounced) is an acoustic-to-electric transducer or sensor that converts sound into an e [..]

an instrument that picks up sounds for radio, television or tape recorders

n. An apparatus for magnifying faint sounds.

This is a device for converting acoustic sound waves into an electrical representation of the sound wave. Microphones are categorised according to several different attributes. For example:

A device designed to convert acoustic sound vibrations into electrical signals, which are usually fed into an amplifier, recording device, or broadcast transmitter. Abbreviated mic or mike.

Essential for making sound recordings in multimedia CALL programs. Microphones used in multimedia applications are much the same as those used with standard audiocassette devices. Choosing the right k [..]

A transducer used to convert acoustic dynamic pressure change into an electrical signal.

A microphone is an input device in an electronic system. It converts sound energy into electrical energy. It is therefore a transducer.

TC, EL A microphone is an input device in an electronic system. It converts sound energy into electrical energy. It is therefore a transducer.

(n) device for converting sound waves into electrical energy

A wired microphone attached to a floor stand that stands 3-6' off the ground.

A fixed microphone at the lectern.

Wired microphones on a table top stand used for panelists.

Most often used for Q & A. We recommend microphones for Q & A when an event is being recorded or is in a room that seats over two hundred people. Q & A microphones can be setup on floor st [..]

A small microphone that clips onto the speaker's shirt or lapel and allows him or her to move around during their presentation. Recommended for the primary speaker of all events.

The air-filled space between the eardrum and the inner ear, containing the ossicles or the three middle-ear bones (the malleus, the incus and the stapes or hammer, anvil and stirrup). 

A transducer which converts sound pressure waves into electrical signals.

Device for converting sound into electrical pulses which can then be amplified or recorded onto tape. Signals from a microphone are very low level and are amplified in the mixing desk to line level. S [..]

An energy converter that changes sound energy into electrical energy. [Microphone Manufacturers].

An electromechanical transducer that converts sound pressure into an electrical signal.
