Phonograph

The term ""phonograph"" was the name used by Thomas Alva Edison for the recording device he patented in 1877, which consisted of a cylinder covered with aluminum foil (and later with wax - the ""phonogram""), the surface of which would be indented with the recording. This example is a Gem model, which was the smallest and least expensive machine offered by Edison and, unlike other models, was housed in an all-metal case. It has a plain cone-shaped bell and encasing wooden lid and base.
