1875 Invention of acoustic wave analysis resonator.

Established a laboratory in Monroe Park, New Jersey in 1876 - the first industrial research laboratory. It was the origin of the modern concept of the "research group". Invented the carbon rod transmitter. Patent for automatic telegraphic recording machine.

Improved and put into practical use an earlier telephone invented by Bell at Menlo Park in 1877. Receives three patents: the perforated pen, the pneumatic iron pen and the ordinary iron pen. On August 20 invented what proved to be one of Edison's beloved projects, the phonograph.

In 1878 Edison claimed to have solved the problem of electric lighting. The Royal Society organized an exhibition of the phonograph. Improvement of the phonograph, the design of microphone, loudspeaker, air loudspeaker, sound engine, tuning engine, microthermometer, odorimeter, etc. February 19th was awarded a patent for the phonograph. July with Professor Parker of the University of Pennsylvania to Wyoming to observe a total eclipse of the sun, and his invention of a thermometer to measure the temperature of the sun around the entire body. August returned to Menlo Park, back to the scientific research and experimentation. Britain approves Edison's patent application for a "tape recorder"; visits William Wallace in Connecticut in September. On October 5, he filed a patent application for a platinum filament "electric light".

1879-1880 years after thousands of setbacks invented high-resistance incandescent lamp. Improved the dynamo. Designed a new method of distributing electric current, and a method of adjusting and calculating electric circuits. Invented electric lamp holders and switches. Invented the magnetic ore analysis method.

August 30, 1879 Edison and Bell each demonstrated a telephone setup at City Hall in Saratoga Creek, with the result that Edison's telephone was clearer than Bell's. October 21 invention of the high-resistance incandescent lamp, which was lit continuously for 40 hours. patented the carbon filament lamp on November 1. December 21 New York Express reported on Edison's incandescent electric lamp. December 25 on the 3,000 visitors from New York City give a public electric light show in Menlo Park.

1880 Research on helicopters. Receives patent for electric light invention. January 28th, the "electric power transmission and distribution system" patent. February 18th, "Scriber Monthly" published "Edison's electric light" article, officially published the invention of electric light. May the first electric light by the electric light "Columbia" ship test sailed successfully.

In May the first ship to be lighted by electric lamps, the "Columbia," made a successful trial voyage.

December established the New York Edison Electric Lighting Company.

1881 New York Fifth Avenue headquarters established. Establishes an incandescent lamp factory in New Yorkk. Establishes a manufacturing plant for generators, underground wiring, and electric light parts. Trolley cars tested in Menlo Park.

1882 Invented the three-wire distribution system for electric current. Applied for 141 patents. September 4, established the first central plant. Over 150 small power stations established throughout the United States of America by the end of December.

May 23, 1885 filed patent for wireless telegraphy.

1887-1890 improved the cylinder phonograph and obtained more than 80 patents on phonographs. Started manufacturing and sales of phonographs, records, and dictation machines.

Invented the cylinder phonograph in 1888.

Participated in the Paris Centennial Exposition in 1889. Invented various types of electric railroads. Completed the moving picture machine.

1890-1899 Designs large stone crusher, grinder. Personally directed the large-scale development of iron ore at the Ogden mine using new methods.

Invented the "Edison Ore Concentrator" in 1891, and started his own mining business. Patented the "Moving Picture Projector," and on May 20, the first successful moving picture projector was demonstrated to the public at Edison's laboratory in West Orange, N.J.

Edison was awarded a patent for the "Moving Picture Projector.

In 1893, the world's first motion picture "studio" was built in the courtyard of Edison's laboratory.

On April 14, 1894, the first moving picture projector theater opened in New York City.

On April 23, 1896, the Vitae projector was used for the first time in New York's Coster-Baylor Music Hall, and was enthusiastically received by the public.

In 1902, a test using a new type of storage battery to power a vehicle traveled 5,000 miles, and was successful in that it could travel 100 miles per charge.

In 1903 Edison's company made its first feature film, Train Robbery.

1909 It took ten years of research on the storage battery, but it finally succeeded. Made facsimile telegraph. Patents were granted for the design of a raw material machine, a finer mill, and a long kiln.

1910-1914 Completion of the disc gramophone, the non-destructive record, and the gold and steel record. Completion of the sound movie machine.

Invention of the "disc record" in 1910.

Invention of the "talkie movie" in 1912. Development of the phonograph.

In 1914-1915, they invented the method of manufacturing carbolic acid, and combined phonographs and teleprinters into teleprinters, which could automatically record each other's speech. Manufactured benzene, indigo oil, etc. on his own.

From 1915 to 1918, the company completed 39 inventions, the most famous of which were the torpedo mechanism, the flamethrower, and the underwater periscope.

Completion of a long time record in 1927.

Rubber was successfully extracted from weeds in 1928.

Some people have made statistics: Edison's inventions in his life, officially registered in the Patent Office, there are about 1,300 kinds of inventions. 1881 is the highest record year of his inventions. This year, he applied for the filing of 141 kinds of inventions, an average of every three days there is a new invention.

The great inventor Edison's life tells us: great achievements, out of hard labor.
