Phonograph
On 21 November 1877, American innovator Thomas Alva Edison has officially credited with inventing the phonograph – a revolutionary device that could record and playback sounds. This invention was saluted with fever at the time, so hugely extraordinary was the idea that we could save the spoken word. Its heritage has converted every aspect of our ultramodern world. Edison first allowed the phonograph, changing 19th-century inventions – the telephone and the telegraph. The technology used for the two, he decided, could also be altered to record sound – a commodity which had here to for no way indeed been considered as a possibility—the original Patent for Edison’s Phonograph.
In 1877, he began to produce a machine with two needles, one for recording the sound, and one for playing it back. The first needle would encode the sound onto a cylinder covered with drum antipode, while the other needle would draw the exact, to produce the same sound again.
When he spoke the oddly chosen words “ Mary had a little angel ” into the machine, he was astounded and astonished to hear them play back to him. Or, maybe, Edison was one of the people to dislike the sound of his voice on the recording.
