Brief history of the microphone

The microphone by Inés Devís 

It is a device used to convert sound waves into electrical energy and vice versa in the process of recording and reproducing sound.

The term "microphone" is known since 1827 when it was first used to describe an acoustic device designed to amplify weak sounds. The word comes from the Greek terms "micro" meaning little and "phon" meaning sound.

Today there is a wide variety of microphones according to the transducer used, according to their usefulness (domestic use to industrial use) and according to quality.
