The Microphone

It was invented in 1876 by Emile Berliner. It is used nowadays by almost every famous person. It converts sound waves into electrical voltages that are eventually converted back into sound waves thru speakers. They were first used with telephones and then radio transmitters. This is now used in big rooms where you can’t hear well; it helps to make the sound get higher.
