History of the Microphone.m4v

The term microphone was coined by Sir Charles Wheatstone in 1827.
However, the very first microphone was invented by Emile Berliner in 1876, to be used as a voice transmitter for Alexander Graham Bell's new invention, the telephone.
Two years later in 1878, David Edward Hughes invented the carbon microphone. It was improved in the 1920s and was an early model for the carbon mics that are still used in telephone transmitters.
The first microphone, that would be considered useful for recording, was a wide range condenser that was developed by E. E. Wente at Bell Labs just before 1920.
