Telephone
Telephone Tel"e*phone, n. [Gr. ? far off + ? sound.] (Physics) An instrument for reproducing sounds, especially articulate speech, at a distance. Note: The ordinary telephone consists essentially of a device by which currents of electricity, produced by sounds through the agency of certain mechanical devices and exactly corresponding in duration and intensity to the vibrations of the air which attend them, are transmitted to a distant station, and there, acting on suitable mechanism, reproduce similar sounds by repeating the vibrations. The necessary variations in the electrical currents are usually produced by means of a microphone attached to a thin diaphragm upon which the voice acts, and are intensified by means of an induction coil. In the magnetic telephone, or magneto-telephone, the diaphragm is of soft iron placed close to the pole of a magnet upon which is wound a coil of fine wire, and its vibrations produce corresponding vibrable currents in the wire by induction. The mechanical, or string, telephone is a device in which the voice or sound causes vibrations in a thin diaphragm, which are directly transmitted along a wire or string connecting it to a similar diaphragm at the remote station, thus reproducing the sound. It does not employ electricity.

Wireless telegraphy or telegraph (Elec.), any system of telegraphy employing no connecting wire or wires between the transmitting and receiving stations. Note: Although more or less successful researchers were made on the subject by Joseph Henry, Hertz, Oliver Lodge, and others, the first commercially successful system was that of Guglielmo Marconi, patented in March, 1897. Marconi employed electric waves of high frequency set up by an induction coil in an oscillator, these waves being launched into space through a lofty antenna. The receiving apparatus consisted of another antenna in circuit with a coherer and small battery for operating through a relay the ordinary telegraphic receiver. This apparatus contains the essential features of all the systems now in use. Wireless telephone, an apparatus or contrivance for wireless telephony. Wireless telephony, telephony without wires, usually employing electric waves of high frequency emitted from an oscillator or generator, as in wireless telegraphy. A telephone transmitter causes fluctuations in these waves, it being the fluctuations only which affect the receiver.
