Answer 2

Thomas Edison created the phonograph by experimenting with methods for recording sound on tinfoil-wrapped cylinders. He discovered that sound waves could be etched onto the tinfoil and played back by a needle vibrating to reproduce the sound. Edison patented the phonograph in 1878 with the intention of creating a device for both recording and playing back sound.
