Records
One of the most important parts of a gramophone is the record register. First introduced in 1892, these discs were available in various sizes from 5 to 10 inches and in 1908, a double-sided version.
Turtable
The turntable’s part of the gramophone used a round steel or aluminum spindle topped with a rubber disc. This helped to hold the sound disc in place and isolate the vibrations when the steel disc turned.
Spider
Inside the gramophone, the spider would be driven with either a belt or an empty wheel. To reduce friction and noise from the rotation, the roller bearing unit was used.
Stylus
The style is the part of the gramophone that came in contact with the audio disc to read the music. Early models employed sapphires and diamonds until they were replaced by copper or steel in the early 20th century.
Horn
Earlier models of the gramophone used a large horn protruding from the device to project the sound. Later models integrated the horn into a full cabinet design. The volume was controlled with a large sound attenuation ball placed in the horn opening. Gramophones, sometimes called phonographs, were early audio devices designed to play back previously recorded sounds. The basic design of the gramophone is quite simple according to modern standards, using a few different parts in operation.
