carbon microphone

electroacoustic device

Quick Summary

A carbon microphone is an electroacoustic device that converts acoustic power into electric power. Its operation relies on changes in the electrical resistance of carbon contacts when sound waves cause a diaphragm to move. This movement alters the resistance of the carbon, creating corresponding variations in an electric circuit. While microphones are widely used in various applications like sound recording and public address systems, the carbon microphone specifically utilizes the principle of varying carbon resistance to translate sound into electrical signals.12
