Who invented the phone? In which year did they come up with a phone

Many know that the phone was invented by Alexander Graham Bell, but if you understand, the idea was developed, even when he was very small. It turns out that he simply appropriated this development. So who invented the first phone? It was Antonio Meucci. How did the long telephone history develop? Who invented the mobile phone? Let's try to understand.

History of the phone

The development of a telephone would become impossible if people did not learn to convert sound vibrations into electrical impulses. In 1833, this was done by KF Gauss and VE Weber in Göttingen. In 1837, discovered a phenomenon that was later called "galvanic music". The electrical circuit consists of a horseshoe magnet, tuning fork and a galvanic cell. During the vibrations of the tuning fork, which open and close the circuit, the electromagnet began to make a melodic sound.

The first words that were spoken on the phone in 1861, went down in history as winged: "The horse does not eat a salad of cucumbers." Therefore, in what year they came up with a phone, it's easy to calculate.

Poor genius

April 13, 1808 in Florence was born the brilliant scientist Antonio Meucci. During his life he founded a factory of stearic candles, a beer factory, in 1860 opened a factory producing paraffin candles, which became the first in the world.

1854 forced Antonio to think about the development of a method for transmitting sound signals at a distance. This thought was pushed by his wife's illness, which was greatly tormented by rheumatism. Sometimes she could not even leave her room.

Not enough money

In 1866, an accident occurred at his plant: a cauldron exploded. Because of this, Meucci was hospitalized for three months. Subsequently, he was fired from his job, and his wife had to sell some of his workings out in order to get some money. Among them were samples of the future phone. Meucci continued to develop, and in 1871 he applied to the United States Patent Office. The lack of finance affected the loss of a patent in 1873.

11. 06. 2002 in the United States adopted a resolution on who invented the phone. Congress recognized the inventor Antonio Meucci. The reason for not recognizing the Italian as the author of the development during life was the lack of knowledge of the English language, in order to understand the subtleties of legal issues. He could not hire a lawyer and defend his rights in court. Even after a detailed presentation of all the nuances of development, which a priori proved his absolute rightness, he did not have only 10 dollars to pay the tax. If he had found the right amount, then the whole world in 1874 would have recognized the primacy of Antonio Meucci, not Bella.

The legal owner of the development

So, in 1876 two patent applicants A. Bell and I. Gray appeared in the Patent Office. Within a few days Bell was given the copyright certificate for "a telegraph device that can transmit human speech." The improved model consisted of a wooden stand, a tank with acid (it served as a battery), an auditory tube and copper wires. The creator called his model a "gallows" for its unusual shape. Gray in the patent refused.

For a long time, the primitive model of the phone remained in the shadows. And only in June 1876 he still decided to show it at an exhibition in Philadelphia. Guests remained indifferent to the presented device until the end of the exhibition. Already at the very close, a tall man stopped by the phone and found himself the emperor of Brazil. He was very interested in the novelty displayed and leaned the earpiece to his ear. What was his surprise when he heard a human voice there! From this moment the novelty became a world sensation and very quickly gained popularity.

Thus, we found out who invented the phone, but the modern communication device is very different from the first one. Technologies have evolved so much that there is practically nothing left to do with the models that are usual for us, except the principle of work. And who came up with a mobile phone, we will find out further.

Cellular development

Cellular or mobile phone is designed to work in cellular communications. For its implementation over the telephone use the usual telephone communication and radio transceiver.

Among all types of mobile communications, cellular is the most common. A mobile phone is often called a cellular phone, although it's not entirely true. Mobile and are the main communications, and radiotelephones, and satellite phones.

Who invented a cell phone and when, not many know. Today without him we can not imagine our life. And the story began, it turns out, not so long ago.

The first idea of telephone communication appeared in 1946 from AT & T Bell Labs. The company has developed the world's first radiotelephone service. It was a telephone hybrid and a radio transmitter. The radio was installed in the car, and only so it was possible to make a call. You could not talk at the same time, because in order to say, you had to press a button like in a walkie-talkie, then, after letting go, you could hear the message in response. The device weighed 12 kg, was located in the trunk of the car, and the console and the tube were taken out into the car's interior. Drilled holes in the car for the antenna!

Who invented a cell phone?

Already in 1957 the Russian scientist L. Kupriyanov experimentally created a model of a mobile phone. His weight was 3 kg. Later, the weight of the device was reduced to 0.5 kg, then to 70 g. In 1973, the world's first portable phone was launched, the first call on which was made on April 3. Motorola DynaTAc, this is the name of this device, had 12 keys, it lacked display and functions. Talking could be only 35 minutes and charging required 10 hours of waiting.

1984 was marked by the appearance on sale of the final model of the mobile phone DynaTAC 8000X. Its price was 3995 dollars! In 1989, released Motorola MicroTac.

Latest phone development

Who invented the phone, we found out, and how did the touch phones? In 1998, the light saw the first touch phone. Although it was developed in 1993 in IBM, which dealt with computer technology. The touch screen reacts to the touch of a finger to enter any information.

Who came up with a touchscreen phone, it's hard to say, it's likely that he was Samuel Hurst. In 1971, he developed an elograph - a graphic tablet. In 1972, the Americans presented the first touch phone. After 10 years, the first sensory TV set was exposed at the fair.

In 2007, there was a touch phone LG KE850 Prada, which had an excellent design and had great opportunities. The phone could be controlled simply with the help of a finger, not a stylus.

So, gradually the phones began to improve, many manufacturers appeared, the gadget became an irreplaceable thing for us, and already who invented the phone, many forgot.
