Ring tone

A ring tone is the sound made by a telephone to indicate an incoming call. The term is most often used to refer to the customisable sounds available on mobile phones. The facility was originally provided so that people would be able to determine when their phone was ringing when in the company of other mobile phone owners.

A phone only rings when a special "ring signal" is sent to it. For regular telephones, the ring signal is a 90-volt 20-hertz AC wave generated from the switch that the telephone is connected to. For mobile phones, the ring signal is a specific radio-frequency signal.
