The relationship between the digits and the musical notes is not limited to that defined in the musical note table 111. The relationship can also be defined by the user. The musical note table 111 is based on the “Just Intonation Music Scale” as an example, but other scales can be used according to manufacturer or user preference.
The music parameters table 112 stores a relationship between a call number character and music parameters, such as rhythm, and an instrumental sound from an instrument. In this embodiment, the call number character has two forms: one form corresponds to digits of the call number, and the other form corresponds to classes of the call number. The call number can be classified according to family, friends, colleagues, classmates, and relatives according to a relationship between the caller and the user, and also can be classified to an unable-recognized call, an international call, a national call, and a local call according to the incoming call number. The relationship between digits and the music parameters are shown in Table 2. The relationship between classes of the call number and the music parameters are shown in Table 3 and Table 4.

Rhythms, in the above Table 2, Table 3, and Table 4, can be set according to a time that each musical note is played. For example, playing three musical notes every second can be set to be played quickly, and playing one musical note every second can be set to be slowly. In practice, the rhythms are not limited to be played quickly and slowly, and can be defined to more kinds of rhythms. The instruments, in the above Table 2, Table 3, and Table 4, are exemplary instrument to play the musical notes.
The audio clip database 113 stores prerecorded audio clips of each musical note played in different instruments. Taking musical note “do” for example, the audio clips of the musical note “do” that is played by different instruments are all stored in the audio clip database. These musical notes may be predetermined as mentioned above.
The processing unit 14 includes an incoming call receiving module 141, a digit obtaining module 142, a music parameter determined module 143, a melody composing module 144, and a music output module 145. The modules 141, 142, 143, 144, 145 may be used to execute one or more operations for the apparatus 1 as will be further described below.
The incoming call receiving module 141 is configured for receiving an incoming call and sending the incoming call to a decoder 12 to obtain a phone number of the incoming call and storing the phone number in the data storage system 11.
The digit obtaining module 142 is configured for selecting one or more digits of the phone number (hereinafter, “the digit set”) stored in the data storage system 11. It may be understood that the digit set may comprise all the digits of the phone number, or may comprise some of the digits of the phone number. For example, if the phone number is “13956123846,” a user, not wanting a long musical note melody, may associate an abbreviated digit pattern with the phone number. The digit pattern may, for example, use only the third, sixth, eighth, tenth, and eleventh digits of the phone number, so the digit set is “91346.” Selective selection of one or more digits of the phone number may be useful for a user to remember who is calling based on the outputted sound.
The music parameter determined module 143 is configured for determining the call number character of the incoming call and obtaining the music parameters from the music parameter table 113 according to the call number character. Taking the above call number “13956123846” for example, if the second digit of the incoming call number is predetermined as a call number character, the music parameter determined module 143 obtains the second digit in the call number “13956123846”, namely the digit “3,” as a call number character, and then obtains the corresponding music parameters of the digit “3,” namely “rhythm is ‘slow,’ instrument is ‘piano’,” in the Table 2.
The melody composing module 144 is for composing a melody according to the digit set from the phone number stored in the data storage system 11. The melody composition process includes receiving a digit set from the digit obtaining module 142, and assigning the musical notes associated with the numbers of the digit set in turn according to the musical note table 111.
The music generating module 144 is for obtaining a corresponding audio clip of each musical note from the audio clip database 113 and outputting the audio clips with the corresponding rhythm of the call number character of the incoming call through the music output apparatus 13.
FIG. 2 is a flowchart of one embodiment of a method for outputting audio signal corresponding to receiving an incoming call. Depending on the embodiment, additional blocks may be added, others deleted, and the ordering of the blocks may be changed. In block S301, the incoming call receiving module 141 receives an incoming call.
In block S302, the incoming call receiving module 141 sends the incoming call to the decoder 12 to decode a phone number of the incoming call and to store the phone number in the data storage system 11.
In block S303, the digit obtaining module 142 obtains a digit set according to the phone number stored in the data storage system 11.
In block S304, the music parameter determined module 143 determines a corresponding call number character of the incoming call for the obtained digit set, and obtains corresponding music parameters from the music parameter table 113 according to the incoming call character.
In block S305, the melody composing module 143 receives the digit set from the digit obtaining module 142 and assigns one or more musical notes associated with the numbers of the digit set in turn according to the musical note table 111.
In block S306, the music generating module 144 obtains corresponding audio clips for each musical note from the audio clip database 113 and outputs the audio clips with the corresponding rhythm of the call number character of the incoming call through the music output apparatus 13.
Although the present disclosure has been specifically described on the basis of various inventive embodiment, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the present disclosure.
