Edison's personal data

Thomas Alva Edison (1847, February11-1,10, 10/8) was born in Milan, Ohio. Inventors and entrepreneurs. 、

Edison was the first person in human history to make use of a large number of production principles and electrical engineering research laboratories to patent inventions, which had a far-reaching impact on the world. His invention of the phonograph, movie camera and electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life. Edison was named the ninth among 100 people who influenced the United States by the authoritative American periodical Atlantic Monthly.

Major achievements

1, phonograph

1877, Edison found that the diaphragm in the telephone transmitter would vibrate with the voice of speech, so he took a short needle and did an experiment, from which he was greatly inspired. Speech speed can make the short needle vibrate accordingly. On the other hand, this kind of vibration will definitely make the original sound, so he began to study the problem of sound reproduction.

In February 65438, Edison publicly demonstrated this "tin foil cylinder phonograph", which caused a sensation all over the world.

2. electric light

Edison didn't invent the electric light at first, but he improved it. As early as 180 1 year, a British chemist named humphry davy used platinum wire to electrify and glow in the laboratory. 18 10, he invented the "electric candle" which was illuminated by the arc between two charged carbon rods, which was the earliest prototype of the electric lamp.

The report about the swan's light bulb gave Edison a great inspiration. 1879 10, Edison finally succeeded in making an incandescent light bulb with carbon fiber as the filament, which is called "carbonized cotton filament incandescent lamp". Later, a large number of incandescent lamps were put into production, and companies were established to establish corresponding power stations, transmission networks and other infrastructure, which soon made electric lamps widely used in the United States.
