Phonogragh
When and How It was invented
The phonograph was invented in 1877 by Thomas Edison. He figured out how to make it while trying to improve the Telephone and Telegraph.
How it has evolved
The phonograph has evolved in many ways. First, it evolved into the radio which was the first way to broadcast information. Next, the sound was changed from a disc or record to a Cassete. Then it was changed back to a much smaller disc or CD. Today it has evolved into the Mp3 player, ipod, or phone.
How it works
The phonograph is very complicated to make but very simple to operate. The phonograph takes a disc with grooves in it and a needle finds the grooves and can vibrate at the right frequency to make music and voices.
