Description: Early phonograph in Deaf Smith County Museum, Hereford, Texas, USA. This is an Edison phonograph, which played recordings made on cylinders of wax. A needle attached to a diaphragm at the narrow end of the flowerlike acoustic horn rested in a groove in the wax which records the sound vibrations. The device was wound up by turning the crank (visible on right side of machine). Then a mainspring in the mechanism turned the wax cylinder, and the displacements of the groove caused the needle to vibrate, which were translated into sound waves by the diaphragm, and came out the horn. Two black wax cylinder recordings are seen in front of the machine.
