telephone

A telephone is a long-distance communication device that can send and receive sound. As early as the18th century, the word telephone was used in Europe to refer to a microphone made of string. 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. This industry is usually divided into telephone equipment manufacturers and telephone network operators.

Historically, network operators usually have a national monopoly position. With the opening and integration of the global telecommunications market and the development of technology, there has been a situation in which many operators compete in the same market. For example, Bell system, that is, AT & amp； T's subsidiary once owned 80% of the American telephone market.
