In addition, the data memory unit 104 selectively stores the music score information converted by the sound source generation and extraction module 103, which will be described later.

When the press event of the key input unit 106 is generated by the user of the mobile communication terminal, the sound source generation and extraction module 103 converts each key press signal constituting the key input unit 106 into a predetermined sound. Recognizes and converts it into a predetermined document format, for example, a text format, and stores the converted sheet music information in the data memory unit 104, and under the control of the terminal controller 101; And selectively extracts music score information stored in 104). In this case, for example, 1, 2, 3, 4, 5, 6, 7, 8, and 9 each key of the key input unit 106 may be degrees, les, me, waves, sol, la, poetry, and semitones. It can be set up or down semitones. In addition to the setting method as described above, various setting methods are possible. An example of a music score converting process using the sound source generation and extraction module 103 is as follows.

TABLE 1

Key number scale One Degree 2 re 3 beauty 4 wave 5 brush 6 la 7 city 8 Halftone 9 Semitone down

TABLE 2

Sheet Music   Sol Solar La Sol Sol Beauty Sheet music information (Text format)  5 ^ 0.5 5 ^ 0.5 6 ^ 0.5 6 ^ 1.0 5 ^ 0.5 5 ^ 0.5 3 ^ 0.8

<Table 1> shows scales corresponding to the respective numeric keys of the key input unit 106, and <Table 2> shows the scales set to the respective numeric keys of the key input unit 106 as shown in <Table 1>. An example of converting general sheet music into sheet music information according to the present invention is shown.

Looking at the transition in detail, in <5 ^ 0.5>, the number 5 represents the scale brush, the number 0.5 represents the duration of the scale brush, and the number 5 and the number 0.5 indicate the duration of the scale. Mediate. In this way it is possible to represent the representation of all scales and the duration of the scale.

Meanwhile, the audio processor 107 converts a voice input from the microphone 112 into a digital signal, or converts a digital signal such as a ring tone or voice into an analog signal and outputs the analog signal to the speaker 111. The melody chip 109 is set to correspond to each key constituting the key input unit 106, for example, the numeric keys 1, 2, 3, 4, 5, 6 of the key input unit 106 , 7, etc. are pressed to generate the sound corresponding to each number, for example, the sound of degrees, les, me, waves, soles, rahs, poems, and outputs the sound to the speaker 111. .

The melody chip control module 108 controls the melody chip 109 to play the sound described in the score information extracted by the sound source generation and extraction module 103 under the control of the terminal controller 101. 111) to control the output. On the other hand, the display window 105 serves to display the operation performance state of the mobile communication terminal.

Referring to the sound source generation method using a mobile communication terminal having such a configuration as follows. First, a plurality of keys constituting the key input unit 106 of the mobile communication terminal, for example, numeric keys are set for each number (S201). For example, as shown in Table 1, a scale is set for each numeric key.

In such a state, an initial screen for generating a sound source is displayed on the display window 105 of the mobile communication terminal, thereby providing a basis for the sound source generation process to proceed in earnest. For reference, the initial screen for generating the sound source is implemented by interlocking a predetermined sound source generating program stored in the data memory unit 104. In the state where the initial screen for generating the sound source is displayed, the terminal controller 101 determines whether a key generation signal is generated from the key input unit 106 (S202). At this time, as described above, each key of the key input unit 106 has a scale set. For example, when a push signal of the number 1 key is generated, a 'degree' sound corresponding to the number 1 key is generated. In detail, the terminal control unit 101 interlocks the melody chip control module 108 to allow the melody chip 109 to correspond to the number key 1 when an input signal of the number key 1 is generated. That is to output the 'degree' to the speaker 111 (S204).

Meanwhile, when sound is generated through the melody chip 109 and the key input signal is generated, the sound source generation and extraction module 103 controls the scale corresponding to each numeric key under the control of the terminal controller 101. In operation S203, a predetermined document form is converted into a text format. See Table 2 for an example of conversion to text format. The score information of the converted text format is selectively stored in the data memory unit 104 (S205). Through the above process, the user can store the sheet music intended by the user. Here, the score information may be stored in various formats such as XML (Extensible Markup Language), HTML document, in addition to the text format.

In the state in which the sheet music desired by the user is stored through the sound source generation process, the output process of the stored sheet music to music is as follows. When a sheet music output event is generated by the user (S206), under the control of the terminal controller 101, the sound source generation and extraction module 103 extracts predetermined sheet music information stored in the data memory unit 104. Based on the extracted sheet music information, the melody chip control module 108 outputs the sounds described in the sheet music information through the speaker 111 under the control of the terminal controller 101. The melody chip 109 is controlled. Accordingly, the melody described in the score information is implemented through the speaker 111 (S208).

On the other hand, since the sheet music information stored in the data memory unit 104 is stored in a kind of digital sheet music data format, the sheet music information is stored in the form of a short message, a memo pad, or the like. Can be sent to. The score information transmitted to another terminal can output a melody through the sound source implementation process.
