1832. Russian diplomat Schilling was inspired by the famous physicist at Oster electromagnetic induction theory, to produce using current meter pointer deflection to receive information telegraph. June 1837, the British youth Cook won the first telegraph invention patents. He made the first telegraph find application in the railway. However, this approach is very convenient and practical, people really can not put a practical stage. History to this critical time, as if stopped down, had to wait for a painter to resolve. 1832 touch screen mobile phone, mail aboard a ship sailing Jackson American doctors in the Atlantic Ocean, to the travelers who speak electromagnet principle, passengers 41 years of American painter Morse was intrigued. France's signal system was only available with a vision clinics and Communications miles ①. Morse dream with the current transmission of electromagnetic signals to transmit information between the twinkling of an eye to the thousands of miles away. After three years of study where the touch screen mobile phone recycling, in 1835, the first telegraph appeared. But how the telegraph and human language linking Morse is placed in front of a big problem, in an instant hint of inspiration comes, he recorded such currents are swift passage in the notebook, if it can not stop walking ten miles, I just let it all over the world. Just stop for a moment the current lot of recycling mobile phone touch screen, there will be a spark, the spark is a symbol, no spark is another symbol, no spark a long time is a kind of symbol. There are three kinds of symbols can be combined to represent numbers and letters. They may be composed of letters, characters can be transmitted by wire. Thus, far from able to spread the message of new tools can be realized! 'Telegraph transmission is professional recycling symbol touch screen mobile phone, send a telegram, the first message was translated into code, then the telegraph sent. In the closed side, to go through the reverse process, the upcoming received code translated into packets and then sent to the person close at hand. This is not only troublesome, but also can not be a two-way exchange of information in a timely manner. Therefore, people began to explore a direct way of transmitting the human voice phone, which is now known to everybody 'phone'. Europe for long-distance transmission of voice studies began in the 18th century, in 1796, Hughes made the transmission of voice information using the microphone relay approach. Although this method is not practical, but he gave a name one way this phone 131 100 'phone), still in use. In 1861, a German teacher invented the most primitive telephones, using acoustic principle can talk to each other at a short distance, but you can not put people really use
