Ringtone

A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone, the term is most often used today to refer to customizable sounds used on mobile phones.

A phone “rings” when its network indicates an incoming call and the phone thus alerts the user. For landline telephones, the call signal can be an electric current generated by the switch or exchange to which the telephone is connected. For mobile phones, the network sends the phone a message indicating an incoming call.

A telephone “ring” is the sound generated when there is an incoming telephone call. The term originated from the fact that early telephones had a ringing mechanism consisting of bells and an electromagnetically-driven clapper, producing a ringing sound. The aforementioned electrical signal powered the electromagnets which would rapidly move and release the clapper, striking the bells. This electromagnetic bell system is still in widespread use. The ringing signal sent to a customer's telephone is 90 volts AC at a frequency of 20 hertz in North America. In Europe it is around 60-90 volts AC at a frequency of 25 hertz

While the sound produced is still called a “ring”, more-recently manufactured telephones electronically produce a warbling, chirping, or other sound. Variation of the ring signal can be used to indicate characteristics of incoming calls (for example, rings with a shorter interval between them might be used to signal a call from a given number).

A ringing signal is an electric telephony signal that causes a telephone to alert the user to an incoming call. On a POTS telephone system, this is created by sending a ringing current, a pulsating DC signal of about 100 volts [90 volts AC and 20Hz in the USA] into the line. Pulsating DC does not alternate polarity; it pulsates from zero to maximum voltage then back to zero. Today this signal may be transmitted digitally for much of the journey, provided as a ringing current only because a majority of landlines are not digital end-to-end. In old phones, this voltage was used to trigger a high-impedance electromagnet to ring a bell on the phone.

Fixed phones of the late 20th century and later detect this ringing current voltage and trigger a warbling tone electronically. Mobile phones are fully digital, hence are signaled to ring as part of the protocol they use to communicate with the cell base stations.

In POTS switching systems, ringing is said to be "tripped" when the impedance of the line reduces to about 600 ohms when the telephone handset is lifted off the switch-hook. This signals that the telephone call has been answered, and the telephone exchange immediately removes the ringing signal from the line and connects the call. This is the source of the name of the problem called "ring-trip" or "pre-trip", which occurs when the ringing signal on the line encounters excessively low resistance between the conductors, which trips the ring before the subscriber's actual telephone has a chance to ring (for more than a very short time); this is common with wet weather and improperly installed lines.

Early research showed that people would wait until the phone stopped ringing before picking it up.[citation needed] Breaks were introduced into the signal to avoid this problem, resulting in the common ring-pause-ring cadence pattern used today. In early party line systems this pattern was a Morse code letter indicating who should pick up the phone, but today, with individual lines, the only surviving patterns are a single ring and double-ring, originally Morse code letters T (dash) and M (dash dash).[clarification needed]

The ringing pattern is known as ring cadence. This only applies to POTS fixed phones, where the high voltage ring signal is switched on and off to create the ringing pattern. In North America, the standard ring cadence is "2-4", or two seconds of ringing followed by four seconds of silence. In Australia and the UK, the standard ring cadence is 400 ms on, 200 ms off, 400 ms on, 2000 ms off. These patterns may vary from region to region, and other patterns are used in different countries around the world.

A service akin to party line ringing is making a comeback in some small office and home office situations allowing facsimile machines and telephones to share the same line but have different telephone numbers; this CLASS feature is usually called distinctive ringing generically, though carriers assign it trademarked names such as "Smart Ring", "Duet", "Multiple Number", "Ident-a-Call", and "Ringmaster." This feature is also used for a second phone number assigned to the same physical line for roommates or teenagers, in which case it is sometimes marketed under the name "teen line".

Caller ID signals are sent during the silent interval between the first and second bursts of the ringing signals.

The interrupted ring signal was designed to attract attention and studies showed that an intermittent two tone ring was the easiest to hear.[citation needed] This had nothing to do with the coded ringing that was used on party lines.

AT&T offered seven different gong combinations for the "C" type ringer found in the model 500 and 2500 landline telephone sets. These gongs provided "distinctive tones" for hearing-impaired customers and to make it possible to tell which phone was ringing when several phones were placed closely together.[1] A "Bell Chime" was also offered, which could be set to chime like a doorbell or to ring like an ordinary phone.

Following a 1975 FCC ruling which permitted third-party devices to be connected to phone lines, manufacturers began to produce accessory telephone ringers which rang with electronic tones or melodies rather than mechanically. People also made their own ringers which used the chip from a musical greeting card to play a melody on the arrival of a call.[2] One such ringer, described in a 1989 book, even features a toy dog which barks and wags its tail when a call arrives.[3] Eventually, electronic telephone ringers became the norm. Some of these ringers produced a single tone, but others produced a sequence of two or three tones or a musical melody.[4]

The first commercial mobile phone with customizable ring tones was the Japanese NTT DoCoMo Digital Mova N103 Hyper by NEC, released in May 1996.[5] It had a few preset songs in MIDI format. In September 1996, IDO, the current au, sold Digital Minimo D319 by Denso. It was the first mobile phone where a user could input an original melody, rather than the preset songs. These phones proved to be popular in Japan: a book[6] published in 1998 providing details about how to customize phones to play snippets of popular songs sold more than 3.5 million copies.

The first downloadable mobile ring tone service was created and delivered in Finland in autumn 1998 when Radiolinja (a Finnish mobile operator now known as Elisa) started their service called Harmonium, invented by Vesa-Matti Pananen.[7], the Harmonium contained both tools for individuals to create monophonic ring tones and a mechanism to deliver them over-the-air (OTA) via SMS to a mobile handset. On November 1998, Digitalphone Groupe (SoftBank Mobile) started a similar service in Japan.

A ring tone maker allows a user to take a song from their personal music collection, select whatever section they like and send the file to their mobile phone. Files can be sent to the mobile phone by direct connection (e.g., USB cable), Bluetooth, text messaging, or e-mail.

The earliest ringtone maker was Harmonium, developed by Vesa-Matti Paananen, a Finnish computer programmer, and released in 1997 for use with Nokia smart messaging.[8][9]

Some providers allow users to create their own music tones, either with a "melody composer" or a sample/loop arranger (such as the MusicDJ in many Sony Ericsson phones). These often use encoding formats only available to one particular phone model or brand. Other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ring tone.

When someone buys a ringtone, an aggregator (company that sells ringtones) either creates their own tune or mixes together a pre-existing one. After the ringtone is created, it is put into a unique file format and sent to the person’s phone via SMS. If the company uses a pre-existing song, they must pay royalties to the person who owns the song. The owner of the song doesn’t get all of the money; a significant portion is given to the cell phone provider.[10]

In 2005 "SmashTheTones" (now "Mobile17"), became the first third-party solution to allow ring tone creation online without requiring downloadable software or a digital audio editor. Later, Apple’s iPhone allowed users to create a ringtone from any song purchased for the phone’s iTunes library[11] but with some difficulties, including a 40-second limit, and the fact the file has to be an AAC format and whose name ended with the extension .m4r.

There are a variety of websites that let users make ring tones from digital music or other sound files; they upload directly to their mobile phone with no limit on the number of songs uploaded.

The fact that consumers are willing to pay up to $3 for ringtones have made "mobile music" a particularly profitable part of the music industry.[12] Estimates vary: the Manhattan-based marketing and consulting firm Consect estimated ringtones generated $4 billion in worldwide sales in 2004.[9] According to Fortune magazine, ring tones generated more than $2 billion in worldwide sales during 2005.[13] The rise of sound files also contributed to the popularization of ringtones. In 2003 for example, the Japanese ringtone market, which alone was worth US $900 million, experienced US $66.4 million worth of sound file ringtone sales. [14] Also in 2003, the global ringtone industry was worth somewhere between US $2.5 and US $3.5 billion. [15]In 2009, the research firm SNL Kagan estimated that sales of ringtones in the United States peaked at $714 million in 2007.[16] SNL Kagan estimated U.S. sales in 2008 declined to $541 million, due in part to consumers having learned how to create their own ringtones.[12]

The ringtone business has prompted controversy about the industry's business practices.

In April 2005, the law firm of Callahan, McCune and Willis filed a class action lawsuit against Jamster! on behalf of a San Diego father and his ten-year-old daughter.[17] The lawsuit alleges that Jamster! scammed cellular telephone customers through the use of fraudulent and deceptive advertisements. The plaintiffs argue that the ads in question offered one free ring tone to cell phone customers who responded to the ad via text message, but failed to inform users that they would be subscribed to a monthly service.[18] The lawsuit was combined with four others and settled in November 2009.[19][20]
