Extended data:
Edison was the first person in human history to make use of a large number of production principles and electrical engineering research laboratories to patent inventions, which had a far-reaching impact on the world. His invention of the phonograph, movie camera and electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life. Edison was named the ninth among 100 people who influenced the United States by the authoritative American periodical Atlantic Monthly.
1877, Edison found that the diaphragm in the telephone transmitter would vibrate with the voice of speech, so he took a short needle and did an experiment, from which he was greatly inspired. Speech speed can make the short needle vibrate accordingly. On the other hand, this kind of vibration will definitely make the original sound, so he began to study the problem of sound reproduction.
/kloc-in August of 0/5, Edison asked his assistant to make a "strange machine" consisting of a large cylinder, a crank, a receiver and a diaphragm according to the pattern. After the production, Edison took out a piece of tin foil and rolled it on a metal cylinder engraved with spiral grooves, so that one end of the needle gently rubbed the tin foil and the other end was connected with the receiver. Then Edison shook his crank and sang to the receiver. After that, he put the needle back.
In February 65438, Edison publicly demonstrated this "tin foil cylinder phonograph", which caused a sensation all over the world.
