Tinfoil phonograph in the style of Thomas Alva Edison

With the tin-foil phonograph, Thomas A. Edison succeeded in recording and reproducing sound mechanically for the first time in 1877. The cylinder covered with tin foil acted as the recording medium. When it is turned and a person speaks into the horn, the sound track is recorded: the membrane inside the sound box moves up and down with the sound. A needle attached to the membrane writes the sound as wave-shaped elevations and depressions in the tin foil. The sound is tinny and flat.
