Several early inventors built primitive microphones, called transmitters, prior to Alexander Bell, but the first commercially practical microphone was the carbon microphone conceived in October 1876 by Thomas Edison. Many early developments in microphone design took place at Bell Laboratories, including the first condenser microphone, described by Wente in 1914. Cheers ebs
