Each functional block exchanges data and instructions via the bus 24.
[0013]
Next, FIG. 3 shows a configuration example of the music reproduction section 15 shown in FIG.
In the illustrated music reproducing unit 15, an interface (I / F) 30 is an interface for transmitting and receiving various data via the bus 24. When initializing music data, music data excluding timbre data is written / written. Under the control of the read controller (R / W controller) 31, the music data is stored in an empty area in the storage unit 32. The timbre data in the music data is supplied to and stored in a timbre data storage unit (Voice RAM) 36. The timbre data storage unit (Voice RAM) 36 is storage means for storing timbre data supplied from the interface 30 and has a storage capacity capable of storing, for example, timbre data for eight tones. Further, the sequencer 33 interprets the music data at the time of initial setting of the music data, applies the tone color number designated for each part to the tone color data storage (Voice RAM) 36, and sets the tone color parameter corresponding to the tone color number to the tone color. The data is read from the data storage unit (Voice RAM) 36 and set in the sound source unit 34.
[0014]
When music playback is started in order to emit a melody at the time of an incoming call or the like, the R / W controller 31 sequentially reads music data from the music data storage unit 32 in response to a read request signal (Req) from the sequencer 33. Is read and supplied to the sequencer 33. The storage capacity of the music data storage unit 32 is smaller than the storage capacity required to store music data for one music piece, and is, for example, a storage capacity capable of storing music data for 32 words. The sequencer 33 sequentially receives the music data from the R / W controller 31, interprets the music data, and sets sound source parameters corresponding to the music data in the sound source unit 34 so that the music data is generated at the sound generation timing. The sound source parameters include pitch data, note on / off signals, and the like.
[0015]
The sequencer 33 detects the octave data and note data of the musical sound to be turned on, and selects the backlight / button light 20 to emit light according to the octave data and note data. In this case, the sequencer 33 selects one of the backlight / button light 20 with reference to a predetermined table. A plurality of backlights / button lights 20 may be selected. Then, a drive control signal for driving the selected backlight / button light 20 is generated. FIG. 4 shows an example of the data format of the drive control signal. The drive control signal causes any one of the brightness data for determining the emission intensity of the backlight / button light 20, the color data for determining the emission color of the backlight / button light 20, and the backlight / button light 20 to emit light. And specified data that specifies Brightness data and color data are also generated from octave data and note data. Alternatively, the brightness data and the color data may be generated based on only the octave data.
[0016]
The drive control signal thus generated is output as a drive control signal (Data) from the sequencer 33 at the note-on sound emission timing, and is sent to the driver 16 via the interface 30 and the bus 24. The driver 16 interprets the drive control signal and supplies the selected backlight / button light 20 with a drive signal capable of obtaining the specified brightness and color to emit light. In this case, it is possible to emit light at the designated intensity by changing the duty of the drive signal according to the brightness data. In addition, by converting color data to RGB data and driving them, it is possible to emit light in a designated color.
The drive control signal (Data) may be directly supplied from the sequencer 33 to the driver 16 as shown by a broken line. Further, monochrome light emission may be used instead of color light emission. Further, the brightness data and the color data may be generated in consideration of the timbre data of the musical tone to be generated, or which of the backlight / button light 20 may emit light in consideration of the timbre data. May be generated.
[0017]
Returning to FIG. 3, the tone generator 34 can simultaneously produce, for example, 12 tone signals, and the tone of each tone signal is set to the tone read from the tone data storage (Voice RAM) 34. The tone signal is generated according to the tone color and based on the sound source parameters set from the sequencer 33. The generated tone signal composed of up to 12 tones is supplied to a digital-to-analog converter (DAC) 35 at predetermined playback timings, and is converted into an analog tone signal.
[0018]
When reading of the music data from the music data storage unit 32 progresses and a predetermined amount of free area is generated in the music data storage unit 32, the R / W controller 31 sends a transfer request signal (Req) to the interface. 30 to the bus 24. The transfer request signal (Req) is read by the CPU 10 from the RAM 11 or the like for predetermined data, for example, 16 words of music data corresponding to an empty area, and sent out to the bus 24. The music data is written into an empty area of the music data storage unit 32 under the control of the R / W controller 31 via the interface 30. By repeating such an operation, the entire music can be reproduced even if the storage capacity of the music data storage unit 32 is smaller than the storage capacity necessary for storing the music data for one music. Become.
[0019]
When the reproduced tone signal is emitted as a ring tone, the amplifier 40 is activated and emitted from the speaker 23 for ring tone. When the reproduced tone signal is a hold tone, the amplifier 37 is activated and output from the receiving speaker 22 via the mixer 38 via the earpiece 7. When the hold sound is set, the amplifier 41 is deactivated so that the reception signal decoded by the voice processing unit 14 is not output.
[0020]
By inserting the tone color assignment data for each part into the musical score data, the tone color of each part can be arbitrarily changed during playback during playback. Further, the user can select the timbre data for eight timbres stored in the timbre data storage unit (Voice RAM) 34 from the timbre data stored in the RAM 11 and set the timbre data in the timbre data storage unit (Voice RAM) 34. At this time, if various timbre data have been downloaded to the RAM 11, the timbre data storage unit (Voice RAM) 34 can select and store arbitrary timbre data from the various timbre data. it can.
Thus, when generating the brightness data, the color data, and the designation data for designating which of the backlight / button light 20 is to be emitted in consideration of the tone color data of the tone to be generated, the set tone color is used. The light emission mode of the backlight / button light 20 can be changed according to the data.
[0021]
The tune reproduced as the ringtone can be a tune or tone corresponding to the telephone of the other party. Specifically, an incoming music song table in which a song number and a tone number are set for each telephone number of the other party's telephone is prepared in the RAM 11. Then, from the telephone number of the other party notified together with the incoming call signal, the music data including the corresponding timbre data is transmitted to the music reproducing unit 15 with reference to the incoming music music table. As a result, the music reproduction section 15 can reproduce the music or tone of the tone corresponding to the telephone of the other party as a ring tone. Therefore, the light emission mode of the backlight / button light 20 can be changed according to the other party, and the other party can be recognized by listening to the incoming melody emitted from the incoming speaker 23.
[0022]
Here, FIGS. 5 and 6 show examples of the manner in which the backlight 20 is divided in the display unit 3.

The timbre data is stored in the timbre data storage (Voice RAM) 36. The sequencer 33 interprets the tone color assignment data, reads tone color parameters for each part from the tone color data storage (Voice RAM) 36 and sets them in the tone generator 34, and sets tempo data in the sequencer 33. However, the music data for the ring tone may be selected and initialized by referring to the incoming music song table from the telephone number information notified from the calling side.
[0025]
When this initial setting process is completed, the reproduction of the incoming melody is started in step S13, and in step S14, the tone of each part based on the sound source parameters given by the sequencer 33 is reproduced by the sound source unit 34 as a ring tone. . Next, in step S15, a light emission process for causing the backlight / button light 20 to emit light is performed according to the musical note and the octave information reproduced, and the generated light emission control signal is output at the sound emission timing. . As a result, the tone reproduced by the sound source section 34 is emitted from the incoming speaker 23, and at the same time, the light emission is controlled in accordance with the tone emitted from the backlight / button light 20.
If it is determined in step S11 that the incoming melody is not turned on, the process proceeds to step S17, where a standard ring tone such as a beep sound is reproduced by the sound source unit 34 and emitted from the speaker 23 for incoming call. A standard incoming notification process is performed. In the standard incoming call notification process, the vibrator 19 may be vibrated instead of the ring tone.

I will go. When the standard incoming call notification process is being performed, the processes in step S14 and step S15 are not performed, and the standard ringtone continues to be sounded.
[0027]
Then, when the incoming call button is operated, it is determined in step S16 that the line is connected, and the process proceeds to step S18, where a stop process for stopping the incoming melody or the standard incoming call sound being emitted as the incoming call sound is performed. Further, the emission control of the backlight / button light 20 is stopped. Specifically, the reproduction in the music reproduction unit 15 is stopped, and the output of the drive control signal (Data) from the sequencer 33 is stopped.
Next, in step S19, processing during the call on the receiving side is performed, and the call is started. When the call is completed, the line is disconnected in step S20, and the incoming call processing ends.
[0028]
Next, FIG. 8 shows a flowchart of the light emission process executed in step S15 of the incoming call process.
When the light emission process is started, the octave and the note information of the music data reproduced in step S30 are detected. Next, the backlight / button light 20 at a position corresponding to the octave and the note information detected in step S31 is selected with reference to the table. Then, the color and the light emission intensity of the backlight / button light 20 selected in step S32 are determined in accordance with the octave and the note information. Next, a drive control signal for the selected color and emission intensity of the backlight / button light 20 selected in step S33 is generated and output to the driver 16 at the tone generation timing of the reproduced musical tone. This terminates the light emission processing and returns to the incoming call processing.
