Next, the operation of the above-described portable telephone will be described with reference to FIGS.
This will be described with reference to FIG. First, the effect setting by the user will be described (see FIG. 4). When the user attempts to set an effect, a predetermined key operation is performed on the operation input unit 4. When this key operation is performed, first, the name, telephone number, and mail address of the person set as the first group (for example, family, relatives) are displayed on the liquid crystal display 8 from the address book in the RAM 3. Subsequently, columns for inputting the effect ON / OFF of individual / group and the effect type are displayed. When the user inputs the effect ON / OFF and the effect type in the field, the input effect ON / OFF and the effect type are set in the address book of the RAM 3.
In the same manner, the user sets the effect ON / OFF and the effect type for the second group (for example, acquaintances and friends) and the third group (for example, company and others). In the example of FIG. 4, for group 1, the individual effects are turned off and the group effect OF is turned off.
F is set, "Reverb 1" is set as a group effect for group 2, and a different individual effect is set for group 3 for each individual. In the case of the same setting within the group, there is an advantage that the setting work becomes easy.

Next, the operation at the time of an incoming call will be described with reference to the flowchart shown in FIG. First, when there is an incoming call, the communication unit 10 detects it (step S1) and outputs the telephone number of the caller to the CPU1. The CPU 1 stores the telephone number of the caller in the RAM 3 (step S2). Then
The CPU 1 compares the telephone number set in the address book in the RAM 3 with the telephone number of the incoming call,
The effect ON / OFF and the type are detected (step S3). For example, if the incoming call belongs to group 1, the effect OFF is detected, if the incoming call belongs to group 2, the effect "reverb 1" is detected, and if the incoming call belongs to group 3, Detects effects unique to that person. Next, the CPU 1 outputs data indicating the detected effect to the music reproducing unit 12 via the bus line 7. This data is supplied to the effector 23 via the interface circuit 15 (FIG. 2), whereby the specified effect or effect OFF is set in the effector 23 (step S4).

Next, the CPU 1 stores the musical tone data in a FIFO
In addition to the transfer to the memory 19, a ring tone start instruction is output to the music reproduction unit 12 (step S5). The interface circuit 15 of the music reproducing unit 12 receives this instruction and outputs a ring tone start signal to the sequencer 20. The sequencer 20 receives this signal, reads out tone data from the FIFO memory 19, and drives the tone generator 21. The tone generator 21 drives a tone generator based on tone control data from the sequencer 20 to form and output a digital tone signal. This digital tone signal is supplied to the effector 23 via the mixing circuit 22. The effector 23 applies the above-described effect to the digital tone signal,
The signal is output to the speaker via the A converter 24. As a result, a ring tone with an effect according to the telephone number of the caller is generated.

Next, the CPU 1 determines whether or not the line has been disconnected (step S6), and the determination result is "NO".
In the case of, it is determined whether or not the off-hook button has been operated (step S7). And the judgment result is “NO”
In the case of, it is determined whether or not the operation of the numerical keys has been performed (step S8). If the result of the determination is "NO", the process returns to step S6 again, and thereafter, steps S6 to S6 are performed until the off-hook button is operated or the numeric key is operated.
S8 is repeated.

If the user listens to the incoming melody and wants to change the effect, he presses a predetermined numeric key. When the numeric key is pressed (the determination in step S8 is "YES"), the effect corresponding to the key is replaced by the effector 23 instead of the currently set effect.
Is set in the address book of the RAM 3 (step S9). Thereby, the effect of the ring tone melody is changed. When the ringing melody is being emitted, an effect change screen for the ringing melody is displayed on the liquid crystal display 8 at any time as shown in FIG.

Next, when the user presses the off-hook button (judgment in step S7 is "YES"), CPU 1 detects this and outputs a stop command to music reproducing section 12 to instruct a melody stop (step S10). ). When this stop command is output, the interface circuit 15 of the music reproducing section 12 instructs the sequencer 20 to stop the musical sound, thereby stopping the incoming melody. Hereafter, C
PU1 performs various processes related to the conversation (step S11). If the caller presses the on-hook button to perform the line disconnection process before the user presses the off-hook button, the determination in step S6 becomes “YES”, and
Proceed to step S12. In step S12, the CPU 1
Sends the above-mentioned ringing melody stop command to the music playback unit 1.
Output to 2.

Next, the operation in the case where the user reproduces a musical sound such as karaoke using the portable telephone will be described with reference to the flowchart shown in FIG. In this case, the musical sound data is downloaded into the RAM 3 via a communication network such as the Internet and the communication unit 10 in advance, or is downloaded from another computer or the like via the interface circuit 5 into the RAM 3. Also, ROM
2 may be stored in advance.

When the user performs a predetermined operation on the operation input unit 4 when, for example, trying to enjoy karaoke with this portable telephone, a list for music selection is displayed on the liquid crystal display 8. When the user selects a music piece from the list (step Sa1), the CPU 1 detects this and reads out the music data or audio data stream of the selected music piece from the RAM 3 and outputs it to the music playback section 12. The interface circuit 15 of the music reproducing section 12 receives this data, and outputs it to the FIFO memory 16 if it is an audio data stream, and outputs it to the FIFO memory 19 if it is musical sound data. FIFO memory 1
6, the stream decoder 17 sequentially reads the data, decodes the data, and outputs the decoded data to the mixing circuit 32. Thereby, a musical tone of the music selected by the user is generated from the speaker (step Sa2).

Here, when the user wants to change the effect of the musical tone, he presses a predetermined numerical key (step Sa3). When the numeric key is operated, the effect corresponding to the key is set to the effector 23 instead of the currently set effect, and the effect is changed (step Sa4). When the karaoke music is being reproduced, an effect change screen as shown in FIG. 8 is displayed on the liquid crystal display 8 at any time. If the user does not press the numeric key, the determinations in steps Sa3 and Sa5 are repeated until the reproduction ends.
