Who is the father of the telephone?

Alexander bell is an American inventor and entrepreneur. He got the first telephone in the world and was praised as "the father of telephone" by the world. The following is a brief introduction of Bell, the father of telephone, which I collected. I hope it helps you.

Introduction to Bell, the Father of Telephone

Alexander Graham Bell * * * Alexander Graham Bell, 1847 March 3rd-1922 August 2nd * * is an American inventor and entrepreneur. He obtained the patent right of the first available telephone in the world, and established Bell Telephone Company in&* *; The predecessor of T Company * * *. There is still controversy about the inventor of the telephone. On June 5th, 2002, the American Congress decided that antonio meucci, an Italian, was the inventor of the telephone, while on June 25th, 2002, the Canadian Parliament passed a resolution of 438+0, reiterating that Bell was the inventor of the telephone. Others believe that Elisha Gray was the inventor of the telephone.

The Life of Bell, the Father of Telephone

Alexander Graham Bell was born in Edinburgh, Scotland, where he received his primary education.

Bell 1870 immigrated to Canada and arrived in the United States one year later. He became an American citizen on 1882.

Bell himself is an acoustic physiologist and a deaf-mute language teacher. Before him, the German Philip Rice had invented the telephone, but its sound transmission effect was too poor to be used in practice. On March 1876, Bell and his colleagues tested the world's first available telephone.

In addition, Bell also invented an instrument for measuring hearing, an instrument that can be used to find metals in the human body and other inventions.

Bell has a patent for the invention of the telephone, but it has also been pointed out that antonio meucci, who immigrated from Italy to the United States, is the inventor of the telephone. In resolution 15 of 2002, the US Congress confirmed that antonio meucci was the inventor of the telephone.

In addition to inventing the telephone, Alexander Graham Bell also invented the manned giant kite, invented the hydrofoil for the Canadian navy to compete with the German U-boats in World War II, and improved the phonograph.

Bell is also an American blind and deaf woman writer, educator, philanthropist, social activist and Helen Keller. She has the longest relationship and is Helen Keller's best friend.

1922 On August 2nd, Alexander Graham Bell died in Badeck.

The story of bell invented the telephone

The invention of the telegraph sent the information people wanted to convey to a long distance at a speed of 300 thousand kilometers per second. This is an epoch-making initiative in the history of human information. But over time, people are a little dissatisfied again. Because the telegram is sent, the telegram draft should be drawn up first, and then translated into code and sent to the operator for transmission; After receiving the message, another operator must first translate the code into words and then send it to the receiver. This is not only complicated, but also unable to carry out two-way information exchange in time; It takes a long time to get the other party's call back.

People's dissatisfaction with telegrams prompted scientists to start new explorations.

This is the first proposal to transmit information through long-distance microphone relay. Although this method is not practical, Hughes' name for this way of speaking-"telephone" has been used to this day.

After 1930s, people began to explore ways to transmit music and sound by electromagnetic phenomena, among which Bell and Gray were the most successful.

Alexander Graham Bell was born in Scotland, England on 1847. His father has been engaged in deaf education all his life. Influenced by his family, he was interested in acoustics and linguistics since he was a child. At first, his interest was studying telegrams. On one occasion, when he was doing a telegraph experiment, he happened to find a phenomenon. An iron piece vibrated in front of a magnet and made a weak sound, and he also found that the sound could be transmitted to a distance through wires. This gave Bell a great inspiration. He thought, if you talk to the iron sheet, won't it also cause the vibration of the iron sheet? This is Bell's original idea about the telephone.

Bell's efforts to invent the telephone were encouraged by the famous American physicist joseph henry at that time. Henry said to him, "You have an idea for a great invention. Go! " When Danbert talked about his lack of electrical knowledge, Henry said, "Learning". Encouraged by Henry, Bell started the experiment. He accidentally spilled sulfuric acid from the bottle on his leg. He cried out in pain, "Mr Watson, come and help me!" " "Unexpectedly, this very common sentence has become the first voice transmitted by human beings by telephone. Watson, Mr. Bell's assistant who works in the other room, was the first person to hear the voice on the phone. Dambert was filled with tears when he learned that his experimental telephone had been able to transmit sound. That night, in his letter to his mother, he predicted: "The day will come when friends can stay at home and talk to each other without going out!" "

Because the transmitter of this telephone used by Bell Company on March 10 1876 is similar to the invention principle of another telephone inventor, Gray brought a lawsuit to the court. Launched a lawsuit on the right of telephone invention, which lasted for more than ten years. Finally, the magnetic telephone based on Bell is different from the liquid telephone in Hugret, and the patent application was filed several hours earlier than Gretel's. The court made a judgment that the result is now known, and the case of telephone invention right came to an end.

Nevertheless, the telephone is still the product of an era, which embodies the wisdom and sweat of many telephone inventors, including Bell.
