Phonograph

The phonograph, or gramophone, was the most common device for playing recorded sound from the 1870s through the 1980sPhonographic recording device invented by Edouard-Leon Scott and the earliest known invention of it was the phonautograph patented on March 25, 1857. It could transcribe sound to a visible medium, but had no means to play back the sound after it was recorded. The device consists of a horn or barrel that focuses sound waves onto a membrane to which a hog's bristle was attached, causing the bristle to move and enabling it to inscribe a visual medium.
