On March 4, 1877 German-American inventor Emile Berliner, working in New York City, invented the microphone. It was first used as a telephone speech transmitter.
A microphone works by converting sound waves into electrical signals. When sound waves hit the microphone's diaphragm, it vibrates and causes a coil or capacitor within the microphone to move, thus generating an electrical signal that represents the sound. This signal is then transmitted to an amplifier or recording device for further processing.
