Telephone is a kind of remote communication equipment that can send and receive sound. The principle of early telephone is that sound is a compound vibration in the air, which can be transmitted to solids and to conductive metals through electric pulses. In the history, the telephone has been improved and invented by color-coded microphone, manual switchboard, dial, automatic telephone exchange, program-controlled telephone exchange, dual-tone multi-frequency dialing, voice digital sampling and so on. This industry is usually divided into telephone equipment manufacturers and telephone network operators. Historically, network operators usually have a national monopoly position. In recent years, with the opening and integration of the global telecommunications market and the development of technology, there has gradually emerged a situation in which many operators compete in the same market.

Telephone communication is a communication technology that converts acoustic energy and electric energy and transmits language through electricity. The simplest way for two users to communicate is to connect two phones with a pair of wires. When the speaker picks up the phone and speaks into the microphone, the vibration of the vocal cords excites the air to vibrate, forming sound waves. Sound waves act on the microphone to generate current, which is called speech current. Voice current is transmitted along the line to the receiver of the other party's phone. A receiver is just the opposite of a microphone-it converts current into sound waves, which are transmitted to people's ears through the air.

The telephone number is the number set by the telephone management department for the telephone.
