In 1871 Meucci filed a patent caveat at the US Patent Office. I have made experiments in this direction they are delicate and demand time and patience, but the approximations obtained promise a favorable result".Īn early communicating device was invented around 1854 by Antonio Meucci, who called it a telettrofono. It is certain that, in a more or less distant future, a speech will be transmitted by electricity. That is about the same time that Meucci later claimed to have created his first attempt at the telephone in Italy.īourseul explained: "Suppose that a man speaks near a movable disc sufficiently flexible to lose none of the vibrations of the voice that this disc alternately makes and breaks the currents from a battery: you may have at a distance another disc which will simultaneously execute the same vibrations.
Innocenzo Manzetti considered the idea of a telephone as early as 1844, and may have made one in 1864, as an enhancement to an automaton built by him in 1849.Ĭharles Bourseul was a French telegraph engineer who proposed (but did not build) the first design of a "make-and-break" telephone in 1854. He observed that connecting and disconnecting the current caused a ringing sound in the magnet.
In 1840, American Charles Grafton Page passed an electric current through a coil of wire placed between the poles of a horseshoe magnet. Gauss's and Weber's invention is purported to be the world's first electromagnetic telegraph. One precursor to the development of the electromagnetic telephone originated in 1833 when Carl Friedrich Gauss and Wilhelm Eduard Weber invented an electromagnetic device for the transmission of telegraphic signals at the University of Göttingen, in Lower Saxony, helping to create the fundamental basis for the technology that was later used in similar telecommunication devices. The essential idea of this toy was that a diaphragm can collect voice sounds from the voice sounds for reproduction at a distance. The classic example is the tin can telephone, a children's toy made by connecting the two ends of a string to the bottoms of two metal cans, paper cups or similar items. Sound waves are carried as mechanical vibrations along the string or wire from one diaphragm to the other. The concept of the telephone dates back to the string telephone or lover's telephone that has been known for centuries, comprising two diaphragms connected by a taut string or wire.
