| The telephone is an instrument that converts voice and other sound signals into a form that can be transmitted to remote locations and that receives and reconverts waves into sound signals." The word telephone is derived from the Greek language. The word tele, meaning afar, and phone, meaning voice. On March 10,1876 Bell had developed the telephone. He used a liquid transmitter, an idea that he had never experimented before or placed in his patent. It was the idea that Gray had patented, and the cause of many lawsuits about to come.

| The history of the telephone dates back to Bell’s research, which began around 1870. Initially he was working on ways to improve the telegraph, which had been used for over 30 years. At the time the telegraph was the primary form of long distance communication. It was the most reliable and accurate way to quickly transmit information. The telegraph used the Morse code system, which consisted of a series of dots and dashes. The idea of a multiple telegraph had been brainstormed, but not actually built. A multiple telegraph would enable multiple messages to be sent through the same line, as long as the pitches of the signals were different. Bell had brainstormed this idea and began working on it. He called his version of the multiple telegraph the harmonic telegraph. For several years he continued to develop a functioning harmonic telegraph.
