Alexander Graham Bell, a Scottish American scientist, was born on March 3, 1847. On March 7, 1876, he received a patent for the phone. Bell, the first telephone company, established the telephone company in 1877.
The Bell telephone company is one of the largest companies in the US today. In addition, there is one for the phonograph that he has developed, five for air vehicles, four for hydroplanes and two for selenium batteries.
His father devoted himself to dealing with the problems of deaf and dumb people. For this reason, Alexander Graham Bell has had some knowledge of the phonetics which, from a young age, will be useful later on.
Bell also began to work in the School of Deaf and Dumb Schools in Boston, first to adhere to life and to conceive himself, deaf students, and indirectly, the world of voices.
The telegraph began to work to find a solution to the problem of the companies' impasse that only one message was transmitted on a line at the same time. At first he wanted to develop a multiple telegram.
Bell was sailing out of the vibrations of the vocal cords and eardrum to find out if it was possible to transmit a signal in the form of an electric signal by obtaining the frequency of the human voice.
For this reason, it was necessary to create an artificial ear drum with diaphragm. The diaphragm was a thin layer that could react to minor changes that could create vibrations with both speech and electrical current.
The diaphragm placed a moving magnetic membrane as it moved in the exact center. The changes caused by the sound vibrations, when reaching the receiver center, caused the vibrations in the diaphragm of the receiver, causing the signals to resound.
Bell, one of the most valuable patents, received the patent on March 7, 1876, four days after the 29th birthday.
Bell Telephone Company, the first telephone company, was founded in 1877.
Bell was also a multi-faceted researcher and inventor. Using oversized three-dimensional box kites
and these studies were carried out only at the station where the experiments were carried out.
To go to the shore. Bell died on August 2, 1922.
