After the mid-19th century, with the telegraph, millet phone shell recycling, electromagnetic waves found the field of human invented the telephone handset has a huge fundamental change, to achieve the use of metal wires to transmit information, even by electromagnetic waves for wireless phones, so the myth of the "ears", "telescope" into a reality. Since then, humans can transmit information from the conventional visual and auditory way to find Obo original phone shell recycling electronics, electrical signal as a new carrier, so bring a series of technical innovations, began a new era of human phones. In this section, we will introduce the 100 years of the most representative of mobile phone technology and mobile way. 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 mobile phone housing recovery, had to wait for a painter to resolve. In 1832, an American doctor on board ship mail Jackson sailing 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, in 1835, the first telegraph appeared. But how the telegraph and connect human language, is placed in front of a big problem Morse Huawei cell phone case recovered 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. Current Just stop for a moment, 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!
