In addition to inventing the electric light, Edison was also the founder of the film industry?
Thomas Alva Edison was born on February 11, 1847. He is a world-famous great inventor. His inventions in his life are unparalleled in the world.
Everyone knows that Edison invented the electric light, but do you also know what he invented?
1. Kinetoscope
In 1889, Edison invented a kinetoscope that used a pointed gear to drive a 19 mm wide tape without holes. , under the control of the ratchet, drives the tape to move intermittently and punch holes at the same time. This kind of camera is driven by a motor, and the shutter shaft is linked to a phonograph. When the camera is running, the phonograph records the sound and can continuously capture images.
2. Kinetoscope
In 1891, Edison invented the kinetoscope, which was an early movie display device and introduced the basic method of movie projection. The illusion of movement was created by using a motor to rotate a strip of film with a succession of pictures at high speed in front of a light source, which projected the pictures on the film onto the screen.
3. Phonograph
On August 15, 1877, Edison asked his assistant to make a "strange machine" consisting of a large cylinder, a crank, a receiver and a diaphragm according to the drawings. , after it was made, Edison took out a piece of tin foil and rolled it on a metal cylinder engraved with spiral grooves. Let one end of the needle lightly rub the tin foil and rotate, and the other end was connected to the receiver. Then Edison shook the crank and pointed it at the receiver. Sing, then put the needle back in place, crank it again, and the machine plays back Edison's voice. In December, Edison publicly displayed this "tinfoil cylinder phonograph", which caused a sensation around the world.
4. Talking movies
In 1910, Edison invented a movie camera that was a combination of a phonograph and a video camera. Under the power of the motor, the camera's light-shielding crankshaft was linked to the phonograph. , the gramophone can record sound while the camera is running. During the screening, the gramophone runs synchronously with the picture, allowing sound and images to appear at the same time.
These four inventions truly pioneered the film industry.
