The Hand Crank Phonograph

In 1887, Edison and Bell are both working on this stuff. Bell has got his wax cylinder going. He played it back on something called a graphophone. You crank that handle, it rotates that wax cylinder and it plays it back through an acoustic trumpet. And then of course later on, the hand crank was replaced with a motor. That was how you listen to music was this guy's invention, the gramophone.
