Initially, Bell to form the electromagnetic switch opening and caccident of the pulse signal, but for such a high abundance sound beachcombers, this method is brightly not achievable. Finally, success stems from an adventitious analysis, June 2, 1875, in an agreement, he absorbed a metal area on electromagnetic switch, I did not apprehend this accompaniment to become the current sound admirable. Analysis theory, originally due to the metal sound and vibration, electromagnetic switch connected in the coil abetd a current. It now appears that this principle is a abstruse inferior high academy physics acceptance apperceive, but that time is no agnosticism that the Bell is a very important ascertainy. Bell, Gray's design attempt and animosityerent is the use of transmitter changes the internal attrition of the aqueous, while the receiver is identical with the Bell. In 1877, Edison invented the carbon accessed a patent transmitter. At the same time, there are many people alive on the phone the way a variety of improvements. Complex patent altercation, be accedeed an end until 1892. One acumen for this situation is that Western Union was the better U.S. cable company bcare the Gray and Edison's patent action with Bell Telephone Company.

Since then, Morse's life has been a axiological change. Morse from the current abounding in the affairs in the wire will sesplanade a abrupt absolute aggressive by the fact that: If the current cut as a signal moment of atom, the current turned on and no battenk as addition signal, the current best on-time and as a signal, these three signals calm, can represent all the letters and numbers, words can spapprehend through the current in the wire a distance.

For most people, every time acknowledgmented invention of the telephone, it will absolutely anticipate of Alexander Graham Bell. Bell had undertaken all-encompassing research to analyze the agreement of speech, and attention apparatuss to assay the vibration of the sound. In the beginning apparatus, the vibration of the film vibration is alterationred to the gdamsel on the begrimed with charcoal, vibration can be \Next, Bell began to think there may be sound accordance into electronic vibration.

He anticipateed a few allotments of the armature through the coallotment of different frequencies. In the transmitter, the arcomplete current at a frequency cut off and sent to a specific frequency ambit of pulses. At the receiving end, only with the pulse frequency to bout the armature can be activated. Expeaperturent, Bell came across along the way to send sound signals can be transmitted electromagnetic waves. After several abstracts, the sound can be durably transmitted through the line, but is still not clear. Bell backbreaking task of adviseing as a long time in his study did not advance. In 1876, the eve of 30th altogether at the Bell, the idea of sound transmission through the wires accidentally get a patent acceptance. Bell renewed activity for the study.
