<Example>

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the electrical configuration of a portable terminal device (for example, a mobile phone) according to the present embodiment. In Fig. 1, reference numeral 1 denotes a CPU (central processing unit) that controls each part of the cellular phone, reference numeral 2 denotes a ROM (Read Only Memory) storing a program of the CPU 1, and reference numeral 3 Denotes a random access memory (RAM) for data storage. In the RAM 3, data such as an address table to be described later are stored, and various effects are set. In addition, the RAM 3 has a battery backup. Reference numeral 4 denotes an operation input unit including numeric keys and function keys, reference numeral 5 denotes an interface (I / F) used for connection to an externally installed personal computer or other portable terminal apparatus, and reference numeral 8 Indicates a liquid crystal display (LCD).

Reference numeral 10 denotes a communication unit (modulation / demodulation unit). The communication unit 10 demodulates the modulated speech signal received through the antenna and outputs the demodulated speech signal to the speech processor 11 or modulates the encoded digital speech signal supplied from the speech processor 11 and transmits the modulated speech signal through the antenna. In addition, the telephone number or other data of the caller received through the antenna is output to the CPU 1 via the bus line 7. The voice processing unit 11 decodes the received voice signal output from the communication unit 10 and outputs it to an ear speaker, or encodes and outputs the voice signal acquired by the microphone to the communication unit 10. Reference numeral 12 denotes a music reproducing section. The music reproducing section 12 generates a music signal based on the music data supplied through the bus line 7 and outputs it to the speaker.

2 is a block diagram showing the internal structure of the music reproducing section 12 in detail. In Fig. 2, reference numeral 15 denotes an interface I / F connected to the bus line 7, and reference numeral 16 denotes a first-in-first-out memory. For example, an audio data stream processed (compressed) by an audio standard such as MP3 (Multilink Protocol 3) is supplied to the FlFO memory 16 via the interface 15 and temporarily stored. Reference numeral 17 denotes a stream decoder, which decodes (extends) the audio data stream output from the FIFO memory 16 to restore original audio data. Reference numeral 19 denotes a FIFO memory for temporarily storing musical sound data, and reference numeral 20 denotes a sequencer. The sequencer 20 reads and analyzes sound data from the FIFO memory 19, and generates sound control data for driving the sound source circuit 21 at a predetermined timing. The sound source circuit 21 has a sound source therein, and the sound source is driven based on sound control data output from the sequencer 20 to generate a digital sound signal. The mixing circuit (MIX) 22 mixes the output of the stream decoder 17 and the output of the sequencer 20. The effector 23 is constituted by, for example, a digital signal processor (DSP). The effector 23 provides a desired effect (effect) to the mixed output of the mixing circuit 22, and the digital / analog (D / A) of the next stage is provided. Output to converter 24. The D / A converter 24 converts the digital output of the effector 23 into an analog signal and outputs it to a speaker (not shown).

The internal configuration of the music reproducing section 12 need not be limited to that shown in Fig. 2, and a configuration corresponding to various methods can be adopted. For example, a sound data format such as SMF or SMAF may be employed, or FIFO or RAM may be employed as the interface format. In addition, FM (Frequency Modulation), PCM (Pulse-Code Modulation), or the like may be employed as the sound source system.

3A to 3D are simple block diagrams showing partial configurations of the effector 23, respectively. In each block diagram, the original sound signal (digital sound signal) A is processed as an input. In FIG. 3A, the coefficient multipliers 31 and 32 are assigned weights to the original sound signal A, and the reverb effect is given to the output of the coefficient multiplier 32 by the reverb circuit 33, and the adder ( 34 adds the output of the coefficient multiplier 31 and the output of the reverb circuit 33 to generate and output a new sound signal A1. Here, the coefficient multipliers 31 and 32 perform the control of the effective amount for the original sound signal A and the on / off control of the reverb effect.

In FIG. 3B, the coefficient multipliers 36 and 37 are assigned a weight to the original sound signal A, and the chorus effect is given by the chorus circuit 38 to the output of the coefficient multiplier 37, and the adder ( 39 adds the output of the coefficient multiplier 36 and the output of the chorus circuit 38 to generate and output a new sound signal A2.

The effect imparted by the effector 23 is not limited to the reverb and chorus described above, and various effects such as delay, echo, equalizer, distortion, and the like can also be imparted. Moreover, not only a single effect but a some effect can also be combined and provided. This example is shown in (c) and (d) of FIG.

In FIG. 3C, the coefficient multipliers 41 and 42 are weighted to the original sound signal A, and the chorus effect is applied to the output of the coefficient multiplier 42 by the chorus circuit 43, and then the reverb circuit ( 44) gives the reverb effect. The adder 45 then adds the output of the coefficient multiplier 41 and the output of the reverb circuit 44 to generate and output a new musical tone signal A3.

In FIG. 3D, the coefficient multipliers 47, 48, and 49 are weighted to the original sound signal A, and the chorus effect is applied by the chorus circuit 50 to the output of the coefficient multiplier 48. The reverb circuit 51 gives a reverb effect to the output of the coefficient multiplier 49. Then, the adder 52 adds the output of the coefficient multiplier 47, the output of the chorus circuit 50, and the output of the reverb circuit 51 to generate and output a new sound signal A4.

The effector 23 is composed of a dedicated DSP (Digital Signal Processor) or a general purpose DSP. In addition, the effector 23 may be composed of separate dedicated hardware.

The effector 23 is supplied with a control signal C1 from the CPU 1 (see FIG. 1) via the bus line 7 and the interface 15 (see FIG. 2), to turn on / off and effect the effect. The type of is specified. In addition, control for realizing a musical effect is performed by the control signal C2 supplied from the sequencer 20.

Next, a specific operation of the above portable terminal device will be described with reference to FIGS. 4 to 8.

4 shows an address table set in the portable terminal device and stored in the RAM 3. The storage area of this address table is classified into a plurality of groups, and names, telephone numbers, mail addresses, and ON / OFF and types of effects are stored for each group. For example, group 1 stores information about family and relatives, group 2 stores information about friends and acquaintances, and group 3 stores information about companies and others. The user operates the predetermined key of the operation input unit 4 to read this address table, and sets various effects on the screen of the liquid crystal display 8. This effect can be set individually or in groups.

First, the user displays on the screen of the liquid crystal display 8 the name, telephone number, and mail address of the person set as the first group from the address table stored in the RAM 3 by operating a predetermined key. Subsequently, a field for inputting the effect ON / OFF or effect type for each and group will be displayed. Accordingly, the user can input the effect ON / OFF or the effect type for each desired individual or group. The input data relating to the effect ON / OFF and the effect type are stored and set in the address table of the RAM 3. Following the first group, the effect ON / OFF and the effect type are also set for the second group and the third group. In the example shown in Fig. 4, the first group is set to OFF of the individual effects and to OFF of the group effects (indicated by a “×” display on the screen). Accordingly, a call with a person belonging to the first group is set. No effect processing is done. In the second group, the group effect is turned ON (indicated by "○" display on the screen), and "reverb 1" is set as the effect type. For this reason, the reverb 1 effect process is performed with respect to the telephone call with the person who belongs to the 2nd group. In the third group, the group effect is turned OFF, but the individual effects are turned ON, and different effects, that is, "distortion", "chorus 1" and "reverb 3" are set for each individual. Moreover, the same setting may be made in each group, and in that case, there exists an advantage that the setting work by a user becomes easy.

In FIG. 5, if there is an incoming call in the standby state of the cellular phone, it is detected by the communication unit 10, and the process proceeds from step S1 to step S2. That is, the communication unit 10 notifies the CPU 1 of the telephone number of the caller, and the telephone number of the caller is stored in the RAM 3 by the CPU 1. Next, in step S3, the CPU 1 inquires about the telephone number set in the address table of the RAM 3 with the telephone number that has received the call, and detects the effect ON / OFF setting and the effect type for the telephone number. . For example, in the case of an incoming call from a person belonging to the first group, the effect OFF is detected. In the case of an incoming call from a person belonging to the second group, "reverb 1" is detected as a kind of group effect. In the case of an incoming call from a person belonging to the third group, an effect type uniquely set for each individual is detected. Next, the process proceeds from step S3 to step S4, where the CPU 1 outputs data relating to the detected effect to the music reproducing section 12 via the bus line 7. This data is supplied to the effector 23 via the interface 15 shown in FIG. Thereby, the effector 23 is notified of the detected effect type or the effect OFF.

Next, the process proceeds from step S4 to step S5, where the CPU 1 reads the corresponding music data from the ROM 2 or the RAM 3 to the FIFO memory 19 in the music reproducing section 12. FIG. In addition to the transmission, the ring tone start instruction is output to the music reproducing unit 12. When the music reproducing unit 12 receives the ring tone start instruction through the interface 15, the music reproducing unit 12 generates a ring tone start signal and outputs the ring tone start signal to the sequencer 20. When the sequencer 20 receives the ring tone start signal, the sequencer 20 reads the sound data temporarily stored in the FIFO memory 19 to drive the sound source circuit 21. In other words, the sound source circuit 21 drives the internal sound source based on the sound control data supplied from the sequencer 20, thereby generating and outputting a digital sound signal. This digital sound signal is supplied to the effector 23 through the mixing circuit 22. The effector 23 gives a predetermined effect to the digital sound signal. The digital sound signal to which the effect is applied is converted into an analog sound signal by the D / A converter 24, and sent to a speaker (not shown). As a result, the ringing tone (or ringing melody) given the effect corresponding to the telephone number of the caller is pronounced from the speaker of the cellular phone.

Subsequent to step S5, the CPU 1 determines whether line disconnection has been made in step S6. If the determination result of step S6 is "no", then the process goes to step S7, where it is determined whether the operation of the off-hook button has been performed by the user. If the determination result of step S7 is "no", then the process goes to step S8, where it is determined whether the operation of the numeric key has been performed by the user. If the determination result of step S8 is "no", the flow returns to step S6 to perform the above determination again. In other words, the CPU 1 repeats the above-described determination process until all of the determination results of steps S6 to S8 become YES.

If you hear the incoming melody and want to change its effect, you can quickly change the effect by pressing a predetermined number key. If the numeric key is pressed by the user, the determination result of step S8 becomes "Yes", and the flow advances to step S9. Here, since a predetermined effect is set in advance in the numeric keys, the effect corresponding to the numeric keys pressed by the user is set in the effector 23 instead of the effects currently set for incoming calls, and the RAM 3 The effect is also changed automatically for the effect stored in the address table. In this way, the user can simply change the effect given to the incoming melody by simply operating the desired number key.

When the incoming melody is reproduced by the cellular phone, the effect change screen as shown in FIG. 6 is displayed on the screen of the liquid crystal display 8, for example. This screen notifies "receive!" And displays the title of the music being played and its effect type. In addition, in order to facilitate the numeric key operation by the user, effect types set corresponding to the respective numeric keys are listed. In the case of Fig. 6, the incoming melody is reproduced by "Reverb 1", and the effect is informed to the user that the effect is indicated by the numeric key "1". So if you want to change the effect type, just press the number key you want. The effect can also be turned OFF by pressing the numeric key "0".

On the other hand, in FIG. 5, when the user presses the off hook button, the determination result of step S7 becomes "Yes", and the process advances to step S10. That is, the CPU 1 detects off-hook button operation and issues an incoming melody stop command to the music reproducing section 12. Upon receiving the incoming melody stop command, the interface 15 of the music reproducing section 12 instructs the sequencer 20 to stop the sound generation. As a result, the pronunciation of the incoming melody by the speaker of the cellular phone is stopped. Thereafter, the process proceeds to step S11, where the CPU 11 performs various processes related to the call with the telephone partner. If the caller side operates the on-hook button before the user presses the off-hook button, and the line disconnection processing is performed, the determination result of step S6 is YES, and the process proceeds to step S12. In step S12, the CPU 1 issues the above-mentioned incoming melody stop command to the music reproducing unit 12 so that the pronunciation of the incoming melody by the speaker of the cellular phone is stopped.

Next, the operation in the case where the user performs music reproduction processing such as karaoke by the cellular phone will be described with reference to the flowchart shown in FIG.

Prior to the above-described sound reproducing process, desired sound data is transmitted to the mobile phone via a communication network such as the Internet, received by the communication unit 10, and then downloaded to the RAM 3. Alternatively, the cellular phone can be connected to a personal computer or the like via the interface 5, input desired sound data, and can be downloaded to the RAM 3. In addition, desired sound data can also be stored in advance in the ROM 2.

When the user performs karaoke playing on the cellular phone, the operation input unit 4 performs a predetermined operation to start the sound reproduction processing shown in FIG. That is, a list of music pieces is displayed on the screen of the liquid crystal display 8, and selection of music by the user is possible. In step Sa1, when the user selects a desired piece of music from the list of pieces of music, the process proceeds to step Sa2. That is, the music data or audio data stream of the music selected by the CPU 1 is read from the RAM 3 and sent to the music reproducing unit 12. The interface 15 of the music reproducing unit 12 transmits the audio data stream to the FIFO memory 16 when receiving the audio data stream, and transmits the music data to the FIFO memory 19. The audio data stream temporarily stored in the FIFO memory 16 is sequentially read and decoded by the stream decoder 17 and then sent to the mixing circuit 22. On the other hand, based on the sound data temporarily stored in the FIFO memory 19, the sequencer 20 drives the sound source circuit 21 to generate a digital sound signal, and sends it to the mixing circuit 22. FIG. In this manner, the sound of the music selected by the user is pronounced by the speaker.

When the user hears the sound pronounced by the speaker and wants to change the effect, he presses a predetermined numeric key. When the numeric key is pressed, the process proceeds from step Sa3 to step Sa4, in which the effect set in advance for the pressed numeric key is set in the effector 23 in place of the effect given to the currently sounding tone. In this way, the user can change the effect applied to the musical notes of the musical tune. When the karaoke music is reproduced, the effect change screen as shown in Fig. 8 is displayed on the screen of the liquid crystal display 8. Here, the words "Karaoke Mode!", The title of the music being played, and the type of effect thereof are displayed. In addition, the effects set on the respective numeric keys are also displayed in a list. If the user does not press the numeric key, the determination process of step Sa3 and step Sa5 is repeatedly performed until the end of reproduction.

As described above, since different effects can be set to correspond to the telephone numbers of a plurality of callers, the user of the cellular phone can easily identify the caller by detecting the difference in the effect given even with the same incoming melody, You can determine which group you belong to. Also, the effect can be changed as appropriate during the generation of the ringing tone.

In addition, the effect can be set or changed appropriately in the karaoke mode. Accordingly, the user of the mobile phone can enjoy music with various sounds, for example, by adding an echo in the karaoke mode, it is possible to give a special effect to the user's song, and to enhance the mood as a singer.

In addition, the structure and operation of the present invention are not limited to the present embodiment, and various changes can be made without departing from the scope of the present invention. For example, music reproduction need not be limited to karaoke and can be applied to ordinary music listening. In addition, programs and data for various processes of the mobile phone realized in the embodiments of the present invention can be stored in various storage media, for example, so-called digital storage media such as memory cards, and mounted on ordinary mobile phones. The function of this embodiment can also be achieved.
