148 years ago today, on December 6, 1877 (November 2, 1877 lunar calendar), the inventor King Edison invented the world's first phonograph. The inventor King Edison invented the world's first phonograph The phonograph was born in 1877. The person who invented the phonograph in the world is the world's famous inventor - Thomas Alva Edison. Thomas Alva Edison based on the phenomenon that the membrane plate in the telephone transmitter vibrates with the sound of speech, and experimented with the short needle, and got great inspiration from it. The speed of speech can cause the short needle to produce corresponding different vibrations. Then, in turn, this vibration must also produce the original sound of speech. So he began to study the problem of sound retransmission. On August 15, 1877, Thomas Alva Edison asked his assistant Chrissy to build a strange machine composed of a large cylinder, a crank, a receiver, and a diaphragm according to the picture. Thomas Alva Edison pointed to the strange machine and said to his assistant, "This is a talking machine." He took out a piece of tin foil, rolled it on a metal cylinder engraved with spiral flutes, and let one end of the needle swipe the tin foil to rotate, and the other end connected to the receiver. Thomas Alva Edison shook the crank and sang to the receiver, "Mary had a little lamb, and the snowballs were like hair...". After singing, he put the needle back in its place and gently shook the crank again. Then, the machine turned unhurriedly, circle after circle, and sang "Mary Had a Little Lamb..." exactly as Thomas Alva Edison had just sung. The assistants on the side were surprised to encounter a talking machine and were speechless. The news of the birth of the "talking machine" caused a sensation all over the world. In December 1877, Thomas Alva Edison performed the phonograph publicly, and the outside world immediately hailed him as "the Napoleon Bonaparte of science", one of the three most exciting inventions of the 19th century. The phonograph designed by American Thomas Alba Edison in 1877 is the earliest recording device in the world. On December 6 of the same year, Edison's assistant, mechanic John Clussy, created the first prototype and used this prototype to record Edison's song "Mary's Goat". Edison and the early phonograph he invented: the first sound in the history of recording was born. The Internet user has this "Mary's Goat" music.
