[0012]
The effector 23 is configured by a dedicated DSP (digital signal processor) or a general-purpose DSP, but may be configured by dedicated hardware. The effector 23 is turned on / off by the control signal C1 supplied from the CPU 1 via the bus line 7 and the interface circuit 15 (FIG. 2), and the effect type is output from the sequencer 20. Control for realizing a musical effect is performed by the control signal C2.
[0013]
Next, the operation of the mobile phone described above will be described with reference to FIGS.
First, effect setting by the user will be described (see FIG. 4). When the user tries to set the effect, the operation input unit 4 performs a predetermined key operation. 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, relative) are displayed on the liquid crystal display 8 from the address book in the RAM 3. Subsequently, fields for inputting individual / group effect ON / OFF and effect type are displayed. When the user inputs the effect ON / OFF and the effect type in the column, the input effect ON / OFF and effect type are set in the address book of the RAM 3. Similarly, the user performs effect ON / OFF and effect type settings for the second group (for example, acquaintances, friends) and the third group (for example, company and others). In the example of FIG. 4, the individual effect OFF and the group effect OFF are set for the group 1, “Reverb 1” is set as the group effect for the group 2, and the individual effect different for each individual is set for the group 3. Is set. In the case of the same setting in the group, there is an advantage that the setting work becomes easy.
[0014]
Next, the operation at the time of 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 CPU 1. The CPU 1 stores the caller telephone number in the RAM 3 (step S2). Next, the CPU 1 detects the effect ON / OFF and the type by collating the telephone number set in the address book in the RAM 3 with the telephone number that received the incoming call (step S3). For example, if the incoming call is a person belonging to group 1, the effect OFF is detected, if the incoming call is a person belonging to group 2, the effect “Reverb 1” is detected, and if the incoming call is a person belonging to group 3 Detects that person's unique effects. 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 designated effect or effect OFF is set in the effector 23 (step S4).
[0015]
Next, the CPU 1 transfers the musical tone data to the FIFO memory 19 and outputs a ringtone start instruction to the music reproducing unit 12 (step S5). The interface circuit 15 of the music playback unit 12 receives this instruction and outputs a ringtone start signal to the sequencer 20. The sequencer 20 receives this signal, reads the musical sound data from the FIFO memory 19 and drives the tone generator circuit 21. The tone generator circuit 21 drives a tone generator based on the tone control data from the sequencer 20, and forms and outputs a digital tone signal. This digital musical tone signal is supplied to the effector 23 via the mixing circuit 22. The effector 23 gives the above-described effect to this digital musical tone signal and outputs it to the speaker via the D / A converter 24. As a result, a ring tone with an effect corresponding to the telephone number of the caller is generated.
[0016]
Next, the CPU 1 determines whether or not the line is “disconnected” (step S6). If the determination result is “NO”, the CPU 1 determines whether or not the off-hook button is operated (step S7). If the determination result is “NO”, it is determined whether or not a numeric key has been operated (step S8). If the determination result is “NO”, the process returns to step S6 again, and thereafter, steps S6 to S8 are repeated until an off-hook button operation or numeric key operation is performed.
[0017]
Here, when the user listens to the incoming melody and wants to change the effect, the user presses a predetermined numerical key. When a numerical key is pressed ("YES" in step S8), the effect corresponding to the key is set in the effector 23 instead of the currently set effect, and is set in the address book of the RAM 3. (Step S9). Thereby, the effect of the incoming melody is changed. It should be noted that whenever a ringing melody is being emitted, an effect change screen for the ringing melody is displayed on the liquid crystal display 8 as shown in FIG.
[0018]
Next, when the user presses the off-hook button ("YES" in step S7), the CPU 1 detects it and outputs a stop command for instructing the music playing unit 12 to stop the incoming melody (step S10). When this stop command is output, the interface circuit 15 of the music playback unit 12 instructs the sequencer 20 to stop the musical sound, thereby stopping the incoming melody. Thereafter, the CPU 1 performs various processes related to the conversation (step S11). If the caller has pressed the on-hook button to disconnect the line before the user presses the off-hook button, the determination in step S6 is “YES” and the process proceeds to step S12. In step S <b> 12, the CPU 1 outputs the above-described incoming melody stop command to the music playback unit 12.
[0019]
Next, an operation when the user reproduces a musical tone such as karaoke using the mobile phone will be described with reference to a flowchart shown in FIG.
In this case, the musical sound data is downloaded in advance into the RAM 3 via the communication network such as the Internet and the communication unit 10, or is downloaded into the RAM 3 via the interface circuit 5 from another computer or the like. Further, it may be stored in the ROM 2 in advance.
[0020]
For example, when the user tries to enjoy karaoke with this mobile phone, when the user performs a predetermined operation on the operation input unit 4, a list for music selection is displayed on the liquid crystal display 8. When the user selects a song from the list (step Sa1), the CPU 1 detects it, reads out the musical tone data or audio data stream of the selected song from the RAM 3, and outputs it to the song playback unit 12. The interface circuit 15 of the music reproducing unit 12 receives this data and outputs it to the FIFO memory 16 if it is an audio data stream, and to the FIFO memory 19 if it is musical tone data. When output to the FIFO memory 16, the stream decoder 17 sequentially reads out the data, decodes it, and outputs it to the mixing circuit 32. Thereby, the musical tone of the music selected by the user is generated from the speaker (step Sa2).
[0021]
Here, if the user wants to change the effect of the musical sound, a predetermined numerical key is pressed (step Sa3). When this numeric key is operated, the effect corresponding to the key is set in the effector 23 instead of the currently set effect, thereby changing the effect (step Sa4). It should be noted that an effect change screen as shown in FIG. 8 is displayed on the liquid crystal display 8 whenever a karaoke song is being played. If the user does not press the numeric key, the determinations at steps Sa3 and Sa5 are repeated until the end of reproduction.
[0022]
【The invention's effect】
As described above, according to the present invention, the first storage means in which the source telephone number and the effect corresponding to the telephone number are set, and the first storage means when there is an incoming call, Since the control means for reading the effect corresponding to the telephone number and instructing the effect giving means to give the read effect is provided, it is possible to change the effect of the ringtone according to the telephone number of the caller. Thereby, even if it is the same ringing melody, a sender | caller can be identified by the feeling of the effect of a ringtone.
[0023]
According to the third aspect of the present invention, the effect imparted to the generated musical sound can be easily changed by an instruction from the operation unit. Thereby, in karaoke etc., the feeling of a singer can be raised by applying an echo. In addition, by changing the effect of music, you can enjoy a variety of music.
Further, according to the invention described in claim 4 or 5, it is possible to immediately detect which group the telephone is from by the ring tone.
