The word "microphone" was developed by Sir Charles Wheatstone in 1827. He used it to describe an all-mechanical vibration stethoscope. The first microphone was invented by Emile Berliner in 1876. This microphone was used as a telephone transmitter by the Bell company. In 1878 the carbon microphone was invented by David Edward Hughes.Hughes discovered that a loose contact in a circuit containing a battery and a telephone receiver created a situation where sounds in the receiver matched the vibrations upon the diaphragm of the telephone mouthpiece or transmitter. The ribbon microphone was invented in 1942 for radio broadcasting. When radios were created, they needed a certain type of microphone specially created for the radio's use. Drs. Walter H. Schottky and Erwin Gerlach co-invented the first ribbon microphone. The electric microphone was invented by James West. The electret
microphone offered greater reliability, higher precision, lower cost, and a smaller size.
