The early recorder was called the phonograph, which was born in 1877. The person who invented the phonograph in the world is Thomas Alva Edison, a world-famous invention King. Today we collected some Boombox tattoos. I hope these tattoos can arouse your memories.

Although Edison invented the phonograph and realized recording. But at that time, tape recorders mainly used mechanical principles to reproduce sound. The volume of the sound it records is so low that it has to shout at the speaker when recording. In order to improve this recording method, Danish scientist Paulson began to try to store sound with magnetism by using the principle of telephone transmission.
