When the mobile phone K1 receives a list of music data from the music download center, the CPU 1 in the mobile phone K1 causes the display unit 5 to display the received music data list, and at the same time, "input a music number. Please display. "(S3). The user selects the music number of the desired music data from the music data list displayed on the display unit 5, and inputs the selected music number from the operation unit 4 (S4).

Next, the CPU 1 causes the display section 5 to display a message "Please input a timbre data number" together with the total number of timbres of the tune data corresponding to the tune number selected by the user (S5). . The user inputs the timbre data number from the operation unit 4 with reference to the total number of timbres of the music data displayed on the display unit 5 and the number of timbres that can be generated by the tone generator 20 of the mobile phone K1 (S6). .

For example, the total number of tones of the music data displayed on the display unit 5 is 10 tones, and the tone generator circuit 2 of the portable telephone K1
Assuming that the number of timbres for which 0 can be generated is four timbres, the user inputs a timbre data number from the operation unit 4 such as “1-4”.

Then, the music number and the timbre data number are transmitted to the music download center, and the music download center stores the tone data corresponding to the timbre data number contained in the music data corresponding to the transmitted music number from the database. Read it out and send it to the mobile phone K1. In the above example, tone data having tone data numbers 1 to 4 is transmitted.

The tone data transmitted from the music download center is input to the CPU 1 via the antenna 7 and the communication section 6 of the portable telephone K1. The CPU 1 sends the input musical tone data to the ring tone generator 11 via the bus line 1a. The tone data sent to the ring tone generator 11 is sent to the tone RAM 18 via the interface circuit 16 and the read / write controller 17 in the ring tone generator 11 and stored there (S).
6).

As in the above example, the total number of tones of the music data displayed on the display unit 5 of the portable telephone K1 is 10 tones,
When the user inputs “1-4” as the timbre data number from the operation unit 4 of the mobile phone K1, the timbre data number is 1 among the ten pieces of music data constituting the music data.
4 to 4 are downloaded.
When the download of the musical sound data is completed, the CPU 1 disconnects the telephone line.

Next, the user operates another portable telephone connected to the mixer unit 13 to perform the same operation as described above. At this time, in step S5, ie, the step of inputting the tone color data number, the tone color data number of the tone data that could not be downloaded earlier is input.
For example, assuming that the number of tones that can be generated by the sound source circuit in the mobile phone K2 is four tones as in the case of the mobile phone K1, the user operates the operation unit of the mobile phone K2 to set “5”.
-8 ". Thereby, the timbre data number is changed from 5 to 8 from the music download center to the mobile phone K2.
The four pieces of music data up to are downloaded. Further, assuming that the tone generator circuit in the mobile phone K3 can generate three tones, the user operates the operation unit of the mobile phone K3 and inputs “9-10” to change the timbre data number from 9 to 9. The two pieces of music data up to 10 are downloaded, and the download of all pieces of music data constituting the music data desired by the user is completed.

Next, an operation of synthesizing one music from a plurality of music data downloaded from the music download center and reproducing the synthesized music will be described. The user operates the reproduction start button 1 provided on the mixer unit 13.
By operating 3a, the music reproduction system is instructed to start reproducing music. Then, a timing signal for starting the reproduction of the music is output from the timing signal output means 13b in the mixer unit 13, and sent to each of the mobile phones K1 to K3 via the cables C1 to C3.

It is sent to the write controller 17. Then, the read / write controller 17 stores the tone RAM 18
Starts the operation of reading out the musical sound data from. Since this operation is started simultaneously in each of the mobile phones K1 to K3,
All the tones of the music data start to be reproduced simultaneously.

That is, when the timing signal is input, the read / write controller 17 sets the tone RA
The tone data is read from M18 and sent to the sequencer 19. The sequencer 19 first sends the tone color data included in the musical tone data to the tone generator circuit 20, and then, at the tempo specified by the tempo data included in the musical tone data, each note in the musical note data string also included in the musical tone data. The data and the rest data are sequentially sent to the tone generator 20. At this time, since the tone data included in the same music data has the same tempo data, the sequencer 19 in each of the mobile phones K1 to K3 sends each note data and rest data to the tone generator circuit 20 at the same tempo. . As a result, all the timbres of the music data are reproduced in synchronization.

The tone generator 20 generates a digital tone signal corresponding to each note data by using a tone generator corresponding to the tone color data sent from the sequencer 19. This digital tone signal is converted into an analog tone signal by the digital / analog converter 21, and the converted analog tone signal is
Output from the input / output terminal 11a.

The analog tone signal output from the input / output terminal 11a is connected to the external terminals K1a to K1a of the cellular phones K1 to K3.
It is output from K3a and input to the mixer unit 13. The mixer unit 13 mixes analog tone signals input from each of the mobile phones K1 to K3 and sends them to the amplifier 14. The amplifier 14 amplifies the mixed analog musical tone signal and causes the speaker 15 to output a musical tone. With the above operation, the music reproduction system reproduces music from music data downloaded from the music download center.

The reproduction start button 13a and the timing signal output means 13b, which are timing control means for controlling music reproduction timing, may be provided in the portable telephones K1 to K3 instead of being provided in the mixer unit 13. In this case, each of the mobile phones K1 to K3 is provided with inter-mobile phone communication means for performing communication between the mobile phones, and one of the mobile phones K1 to K3 is used as a master, and the mobile phone as a master is used. A timing signal is generated from the timing control means included in the mobile phone, and the timing signal is transmitted to each mobile phone by the inter-mobile phone communication means, thereby controlling the timing of music reproduction. The communication means between mobile phones may be a means for connecting the mobile phones by wire or a means for connecting wirelessly.

It is also possible to assign a serial number to a plurality of portable telephones and use this serial number to prevent the music data from being downloaded redundantly. For example, the configuration may be such that the instruction for downloading the tone data is collectively performed from the master mobile phone, and the serial number and tone data number of each mobile phone may be input at the time of downloading.

Further, in the above embodiment, the mixer unit 13 and the portable telephones K1 to K3 are separate bodies, but it is also possible to provide the mixer unit in the portable telephone.
