We have a Phonograph Horn in our Technology through Time Collection.
The phonograph was the first device available to the public which could play recorded sound. It played wax or tinfoil cylinders - each one contained one song. Early phonographs played music using grooves in records and cylinders. These caused vibrations to travel from the stylus needle to the diaphragm. The vibrating diaphragm then generated sound waves, which were carried out through the horn.
