The Phonograph.

Edison invented the first sound recording device which was patented on February 19, 1878.

He attached a needle to a telephone receiver and placed it close to a foil cylinder. The needle made indentations in the foil cylinder recording the vibrations caused by the sound of the voice. He was able to play back the message he had created realising he had invented a device to record sound.  

This brought him international fame.

In May 1889, the first "phonograph parlor" opened in San Francisco.
