carbon microphone

n (Electrical Engineering) a microphone in which a diaphragm, vibrated by sound waves, applies a varying pressure to a container packed with carbon granules, altering the resistance of the carbon. A current flowing through the carbon is thus modulated at the frequency of the sound waves

Carbon Microphone

carbon microphone

[¦kär·bən ′mī·krə‚fōn] (engineering acoustics) A microphone in which a flexible diaphragm moves in response to sound waves and applies a varying pressure to a container filled with carbon granules, causing the resistance of the microphone to vary correspondingly.

Carbon Microphone

a microphone in which carbon granules are used to convert sound vibrations into electrical variations. Carbon microphones are distinguished from other microphone systems by their extremely high sensitivity and their simplicity of design; their quality characteristics, however, are poor. The microphones are used primarily in telephony.
