About Invention

The phonograph was invented in 1877 by Thomas Edison.While other inventors had produced devices that could record sounds, Edison's phonograph was the first to be able to reproduce the recorded sound. His phonograph originally recorded sound onto a tinfoil sheet phonograph cylinder, and could both record and reproduce sounds. Alexander Graham Bell's Volta Laboratory made several improvements in the 1880s, including the use of wax-coated cardboard cylinders, and a cutting stylus that moved from side to side in a "zig zag" pattern across the record.


Thomas Edison created many inventions, but his favorite was the phonograph. While working on improvements to the telegraph and the telephone, Edison figured out a way to record sound on tinfoil-coated cylinders. In 1877, he created a machine with two needles: one for recording and one for playback. When Edison spoke into the mouthpiece, the sound vibrations of his voice would be indented onto the cylinder by the recording needle. What do you think were the first words that Edison spoke into the phonograph? "Mary had a little lamb" were the first words that Edison recorded on the phonograph and he was amazed when he heard the machine play them back to him. In 1878, Edison established the Edison Speaking Phonograph Company to sell the new machine.


Edison suggested other uses for the phonograph, such as: letter writing and dictation, phonographic books for blind people, a family record (recording family members in their own voices), music boxes and toys, clocks that announce the time, and a connection with the telephone so communications could be recorded.
