chosen.content: The first microphone was invented by German-born Emile Berliner. His creation worked by varying the contact pressure between two terminals as a voice acted against it. Berliner sold the patent of his carbon microphone to the fledgling Bell Telephone Company for $50,000. The carbon microphone then became part of the first Bell telephones.
