What is Ringtone in phone?

A ringtone, ring tone or ring is the sound made by a telephone to indicate an incoming call. Originally referring to and made by the electromechanical striking of bells, the term now refers to any sound on any device alerting of a new incoming call—up to and including recordings of original telephone bells.

Background and history

A telephone rings when the telephone network indicates an incoming call, so that the recipient is alerted of the call attempt. Landline telephones typically receive an electric alternating current signal, called power ringing or ringing signal, generated by the telephone exchange to which the telephone is connected. The ringing current originally operated an electric bell. For mobile phones, the network sends a message to the recipient's device, which may activate a sound, or a visual or vibrating indication.

Generation software
A ringtone maker is an application that converts a user chosen song or other audio file for use as a ringtone of a mobile phone. The ringtone file is installed in the mobile phone either by direct cable connection, Bluetooth, text messaging, or e-mail. On many websites, users may create ringtones from digital music or audio.

Commercial sales and popularity
In September 1996, IDO sold Digital Minimo D319 by Denso. It was the first mobile phone where a user could input an original melody, rather than having to use preloaded melodies. These phones proved to be popular in Japan, with a book being published in 1998 providing details about how to customize phones to play snippets of popular songs, selling more than 3.5 million copies.

Decline of popularity
SNL Kagan estimated U.S. sales of ringtones in 2008 declined to $541 million, as consumers utilized third-party software and tutorials to create ringtones themselves. Another reason for the decline of ringtones is due to the increase of mobile devices in the late 2000s having internet connectivity, allowing consumers to download full songs from marketplaces such as iTunes and Amazon, rather than buying excerpts for $5 through text.

Cult following

Preloaded ringtones have also developed a cult following over the years. A Twitter account named Ringtone Bangers + More launched in 2020, posts preloaded ringtones from mobile phones, as well as other music related to technology such as demoes from keyboards and software installation background music.
