Background and Identification
A turntable, or phonograph as it was once commonly known, is a device capable of turning the physical deviations on the surface of a spinning disc, or record, into sound waves. The record, which can be engraved, etched, incised, or impressed with the grooves corresponding to the sounds desired, is traced with a stylus, which vibrates with different frequencies depending on the nature of the grooves. These vibrations are then amplified, in early years with a horn but now digitally, to produce the desired sounds.
The phonograph was invented by Thomas Edison in 1877 and improved by Alexander Graham Bell’s laboratories in the 1880’s. Through most of the 20th century, the phonograph was actually used as the primary method for recording audio, with devices having the functionality to “write” discs by actively etching the grooves based on the input sound waves. Nowadays, records are mass produced by stamping out records with a press, and the ability to record sound has been removed.
Turntables are also commonly known as record players or gramophones.
Turntables typically consist of a large box, at least 12 inches in width and depth, with a spinning component in the center and a long stylus on a pivot capable of moving to and fro across the radius of the spinning disc.
