1 Jan 1868 Jahr - SOUND STORAGE: PHONOGRAPH

Beschreibung:

Description: an old-fashioned machine that plays music recorded on an engraved disk.
History: When Thomas Edison invented the phonograph in 1877, he created the first technology for recording and reproducing sounds as perceived by people. Edison used a vibrating stylus connected to a sound collecting horn to record sound vibrations as a vertical pattern of waves on the surface of a rotating tinfoil cylinder. The tinfoil was soon replaced by wax, and the cylinders, which were hard to produce economically, evolved into the familiar, and less expensive, phonograph disks (1877), much to Edison's discontent.

Special Features: reproduces sounds by means of the vibration of a stylus, or needle, following a groove on a rotating disc.

Uses: It can both record and play sounds
