Are there any invention that similar to the microphone?

All forerunners are similar to the microphone. Several early inventors built primitive microphones or telephones, called transmitters, prior to Alexander Bell (born in Scotland), but the first commercially practical "microphone" was the carbon microphone conceived in October 1876 by Thomas Edison (USA). Many early developments in microphone design took place at Bell Laboratories, including the first condenser microphone, described by Edward Christopher Wente of Western Electric Engineering in 1914.
