How record players work

In 1877, Thomas Edison and his assistants connected a needle to the diaphragm of a telephone receiver with the concept that the needle will be used to etch an influence of sound onto quickly moving paper, for that reason creating a recording or sound writing.

Edison understood that sound is the Record Player across a medium, such as air, in waves. He developed a way to imprint or document the waves so they will be performed back or grew to become again into sound the usage of a 2nd needle.

He finally designed a tool he called the phonograph that had a brass cylinder wrapped in tinfoil, which rotated and moved lengthwise whilst became by a hand crank. On one facet changed into a diaphragm, or very skinny membrane, linked to a needle. whilst sound waves were forced into the receiving stop, it brought about the membrane to vibrate and the needle to etch a groove into the foil as the cylinder turned into being became via the crank, consequently recording sound. A 2nd needle and an amplifier had been on the other aspect. when the cylinder changed into set to the start and the needle located in the grooves, the original sound was reproduced because the vibrations had been amplified.

Edison created his first voice recording with the aid of shouting the phrases to “Mary had a bit lamb” right into a mouthpiece, inflicting the sound waves to vibrate a needle and etch the nursery rhyme into tinfoil for playback.
