The Phone

The phone is a telecommunications device designed to transmit sound signals through electrical signals remotely.

For a long time was considered Alexander Graham Bell invented the telephone, along with Elisha Gray. But Graham Bell was not the inventor of this device, but only the first to patent it. This happened in 1876. On June 11, 2002 the U.S. Congress passed resolution 269, which recognized by the inventor of the telephone was Antonio Meucci, who called teletrofono, and Alexander Graham Bell. In 1871 Meucci could only by economic difficulties, present a brief description of his invention, but not to formalize the patent before the Patent Office of the United States.
