It was the first time the human voice had been recorded. Edison's phonograph (see ad above) was simply built. Vibrations from the voice of a person speaking into a mouthpiece caused a needle to move and scratch a piece of tinfoil wrapped around a rotating cylinder. To play back the sound, the needle was once again run around the cylinder, causing mechanical vibrations. The machine transformed the vibrations into electrical signals and then into sound waves.
