Microphone

In honor of Microphone Month... Microphone - The word "microphone" comes from the Greek words "micro", meaning "small", and "phone" meaning "voice". A microphone is a transducer, or instrument whereby sound waves are caused to generate or modulate an electric current usually for the purpose of transmitting or recording sound. In all microphones, sound waves are translated into mechanical vibrations in a thin, flexible diaphragm. These vibrations are then converted by various methods into an electrical signal.
