1875, Bell heard the bell on the wire when he was doing the experiment. This inspired him; Together with his assistant, Thomas A. Watson, an electrician, he tirelessly continued to do experiments to create a device that can spread sound.
Finally, on March 1876 10, Bell said the first sentence by phone, "Mr. Watson, come here, I want to see you!" Their words were clearly heard on the other side. The date above is the official date when Alexander Graham Bell invented the telephone.
Alexander Graham Bell won many awards for his extraordinary performance in his life. However, the irony is that although he invented the telephone, he never used it because he thought it would interfere with his work.
After the invention, several public demonstrations and exhibitions were held to publicize his invention. Bell Telephone Company was established in 1877 and started mass production. Within a year, thousands of Americans had telephones.
Representative figures of the telephone invention year:
1832
The invention of electromagnetic telegraph is generally regarded as the basis of the invention of telephone or communication equipment. Pavel Schilling invented the electromagnetic telegraph in Russia. It is used to send signals from one person to another.
1844
The Italian inventor InnocenzoManzetti put forward the idea of making talking telegraph (later called telephone). However, it was not until 1864 that he really invented this device. However, he did not apply for a patent for this.
1854
Antonio Mache invented a device very similar to the telephone. Mikey used this device to connect his basement with the bedroom on the first floor. Due to economic and other reasons, Miki did not apply for a patent for his equipment.
1860
John philip Reese made an important invention very close to the telephone. It can help transmit sound over 100 meters.
1874 In May, Irina Captier Gray invented an electromagnetic device for transmitting musical tones.
1On June 2nd, 875, AlexanderGrahamBell used similar equipment to transmit the sound of reeds.
1876 February 14, Bell and Gray applied for the telephone patent within two hours of the same day (Gray applied first, Bell applied later).
1On March 7th, 876, Gray failed to turn his invention into a patent application. So the patent was awarded to Bell.
In March 1876, 10, Bell made the first call and said a few famous words on the phone: "Mr. Watson, come here, I want to see you!"
The first long-distance call was made between Cambridge and Boston.

The first videophone, the first commercial mobile phone, the first touch-tone phone, the first mobile phone, the first caller ID and so on. Some of the greatest inventions appeared in 2 1 century, including smart phones, such as iPhone.
