Phonograph
Where would our world be?
What's a phonograph?
A phonograph is an invention created by Thomas Edison in 1877. This invention is a mechanical recording and reproduction of sound, and it's also known as a record player or gramophones. This device was used for listening to music and other recordings during the mid-1980's. To record sound, you wrap tinfoil around a metal cylinder. Then a needle attached to the diaphragm is placed against the cylinder, which was rotated by a hand crank. When someone speaks into the mouthpiece the vibrations move the diaphragm a the needle vibrates, which is how they record the noise. Then the noises will play back nearly just the same as the sound was recorded from the indents of the tinfoil.
