Carbon Microphone

Carbon microphones are a type of microphone that falls under the supply class of Headsets, Handsets, Microphones, and Speakers in the supply group of Electrical and Electronic Equipment Components.

Carbon microphones are a type of dynamic microphone that use carbon granules to convert sound waves into electrical signals. They consist of a diaphragm, a carbon button, and a backplate. When sound waves hit the diaphragm, it vibrates, causing the carbon granules to compress and release. This compression and release of the carbon granules changes the resistance of the carbon button, which in turn changes the electrical current flowing through the microphone. This varying current is then amplified and converted into an audio signal.

Carbon microphones were widely used in early telephony and broadcasting systems due to their simplicity and reliability. However, they have been largely replaced by more modern microphone technologies such as condenser and dynamic microphones.
