Thomas Edison created the phonograph in 1877. It was created solo shortly after the teleph unity and the telegraph, once he power saw the results from those he released the phonograph. Omphlegraph, antiphone, and didaskaphone are just some of the names soul wrote in the log book in Thomas Edisons laboratory in 1877 for the phonograph. At number one, they thought it would be utilise to reproduce the human voice, but they had no clear estimation of its exact purpose (Stross, 2010).
Edison once said Anything that wont sell, I dont want to invent. But wholly his life, he was a better inventor than a salesman. The phonograph, his first invention to make him world-famous, is a perfect example. It was the product of a well-prepared but wandering mind. In 1877, Edison was working on a machine that would transcribe telegraphic messages through indentations on composing tape, which could later be sent over the telegraph frequently. This continue led Edison to risk that a telephone message could also be recorded in a similar fashion. He tested with a diaphragm which had a stamping point and was held against rapidly-moving alkane series typography. The speaking vibrations made indentations in the paper (Stross, 2010).
Edison later changed the paper to a metal cylinder with tin foil cloaked around it. The machine had two diaphragm-and-needle units, one for recording, and one for playback. When one would speak into a mouthpiece, the sound vibrations would be indented onto the cylinder by the recording needle in a vertical (or cumulus and dale) groove pattern. Edison gave a sketch of the machine to his mechanic, John Kreusi, to build, which Kreusi purportedly did within 30 hours. Edison immediately tested the machine by speaking the nursery rhyme into the mouthpiece, Mary had a particular lamb. To his amazement, the machine played his words back to him (Bellis, n.d., para 1).
