Description

  The present invention relates to a terminal device such as a mobile phone, a PHS (registered trademark), a PDA, and a fixed communication device, and more particularly, to an effector mounted with an effector (effect applying circuit) for applying an effect to an incoming melody or the like. It relates to a terminal device.

2. Description of the Related Art In desktop music, an effect is applied to a musical tone signal output from a sound source by an effector to make the musical tone more musically preferable.
Effectors are often configured using a DSP (Digital Signal Processor), and various types of effects can be created by changing the microcode of the DSP. For example, FIG. 7 is a diagram showing a block configuration of an effector that gives reverb and an effector that gives distortion, and in this figure, each block has the following functions.
LPF: Low pass filter HPF: High pass filter APF: All pass filter COMB: Comb filter Distortion: Distortion conversion circuit LSF: Low shelving filter HSF: High shelving filter

The following effect parameters used in the function block are described below each function block.
Cut off Freq: Cut-off frequency Density: Density Initial Delay Time: Initial delay time Revever Delay Time: Reverb delay time Feedback Level: Feedback level Gain: Gain These effect parameters are created as variables on the DSP microcode. The effect degree of the effector can be determined by arbitrarily giving the effector.
Further, as an application example of the effector, there is known a technology in which an effector function is mounted on a portable karaoke apparatus to change the voice of a singer (for example, see Patent Document 1).
JP 2003-108164 A

By the way, all the effectors in the conventional desktop music are fixed effectors, and therefore, there are few types of effects that can be provided, and there is a disadvantage that the user is easily bored, and the musical tone is dynamically changed even if the parameters are changed. There was a drawback that could not be done. This is true even if such an effector in desktop music is simply diverted to a mobile phone.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide an effector-equipped terminal device capable of greatly changing an effect as compared with the related art.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a mobile terminal device 1 (a mobile phone in this embodiment) and a download site 2 for distributing ringtones and the like according to the embodiment. FIG. 2 is a block diagram showing a hardware configuration of the mobile terminal device 1. FIG. 3 is a functional block diagram showing a functional configuration of the mobile terminal device 1.

  2, reference numeral 5 denotes a CPU (Central Processing Unit), 6 denotes a ROM (Read Only Memory) in which a program used in the CPU 5 is stored, 7 denotes a RAM for temporarily storing data, and 8 denotes a mobile terminal device 1. This is an external interface used when connecting another portable terminal device or personal computer. A communication unit 9 demodulates a signal received via the antenna 10 to return to compressed audio data, outputs the compressed audio data to the audio CODEC 11, and places the compressed audio data output from the audio CODEC 11 on a carrier wave, and Send. In addition, data such as the telephone number of the transmission source received via the antenna 10 is output to the CPU 5 via the bus line B.

The audio CODEC 11 expands the compressed audio data supplied from the communication unit 9, converts the data into an analog audio signal, and outputs the analog audio signal to the speaker 12. Further, the audio signal from the microphone 13 is converted into digital data, compressed, and output to the communication unit 9.
Reference numeral 15 denotes a sound source, which forms a digital musical tone waveform corresponding to a sound generation parameter supplied via the bus line B. This sound source 15 is constituted by dedicated hardware or a DSP. Reference numeral 16 denotes a DSP used for an effector or the like. The digital ringtone melody signal to which the effect has been added by the DSP 16 is converted into an analog signal and output to a ringtone speaker (see reference numeral 26 in FIG. 3).

  Next, in FIG. 3, reference numeral 21 denotes music data of the incoming melody. Reference numeral 22 denotes a sequencer for generating a ringing melody, which converts event data included in the music data into sound generation parameters at intervals of time data included in the music data 21, and sequentially outputs them to the sound source 15. The sound source 15 forms a digital musical tone signal specified by the tone generation parameter supplied from the sequencer 22, and outputs it to the selector 23. The selector 23 selects one of the digital audio signal output from the audio CODEC 11 and the digital tone signal output from the sound source 15 and outputs the selected signal to the effector 24.

  The effector 24 is a circuit for applying an effect to the digital signal supplied via the selector 23 according to an effect program 25. That is, the effector 24 becomes, for example, a reverb effect imparting circuit shown in FIG. 7, a distortion effect imparting circuit, or another effect imparting circuit in accordance with the effect program 25. The effect program 25 is written in a memory in the DSP 16 in FIG. 2, and the DSP 16 operates according to the program written in the memory to function as an effect applying circuit. The output of the effector 24 is returned to the voice CODEC 11 or converted to an analog signal and output to the ring tone speaker 26.

The portable terminal device 1 described above can be connected to the download site 2 via the Internet, as shown in FIG. In download site 2,
(1) Song data of ringtone melody
(2) Effect program
(3) Set of ringtone melody music data and effect program
(4) A plurality of voice conversion effect programs are prepared. In this case, (2) the effect program and (4) the sound conversion effect program are prepared as one of the Java (registered trademark) applications. Then, the user of the portable terminal device 1 can access the download site 2 to select and download a desired music data or effect program.

Next, the operation of the above-described embodiment will be described with reference to the flowcharts shown in FIGS.
(1) Download: Fig. 4
When the user of the portable terminal device 1 wants to receive, for example, a set of the music data of the ringtone melody and the effect program, the user accesses the download site 2 and makes a request to that effect (step Sa1). The download site 2 receives the request and transmits a list of the incoming melody to the mobile terminal device 1. The transmitted list is displayed on the display of the mobile terminal device 1. When the user selects a favorite song from the list, the download site 2 transmits to the portable terminal device 1 the song data of the selected ring melody and an effect program for giving an effect to the ring melody (step Sa2). . The portable terminal device 1 checks whether or not the transmitted data is music data (step Sa3), and if it is music data, registers it in a predetermined music data area in the RAM 7 (step Sa3). Sa4) If the program is an effect program, it is registered in the effect program area in the RAM 7 (step Sa5).

The same applies to the case where the user of the portable terminal device 1 wants to receive only the download of the effect program, for example. When the user accesses the download site 2 (step Sa1), a list of the effect programs is transmitted from the download site 2, When the user selects a favorite program from the list, the download site 2 transmits the selected effect program to the portable terminal device 1 (Step Sa2). The mobile terminal device 1 registers the transmitted effect program in the effect program area in the RAM 7 (step Sa5).
When the user of the mobile terminal device 1 wants to receive only the music data of the ringtone melody or the download of the sound conversion effect program, the same processing as described above is performed.

(2) User processing: FIG.
After receiving the above-described download, the user of the mobile terminal device 1 performs preprocessing for using the received ringtone or the effect program.
That is, first, the user designates whether to use the effector 24 for applying the effect of the conversation voice or to use the effect of the incoming melody by using the operation keys of the mobile terminal device 1 (step Sb1). When this designation is made, the selector 23 is switched based on the designation (step Sb2).

  Hereinafter, the case where the incoming melody is specified will be described. After designating the ringing melody, the user next specifies which song is to be used as the ringing melody (step Sb3). That is, when the user performs a predetermined key operation on the portable terminal device 1, the CPU 5 displays a list of incoming melody stored in the incoming melody area of the RAM 7 on the display. When the user selects an incoming melody from the displayed list, the music data of the selected incoming melody is transferred from the incoming melody area of the RAM 7 to the execution data area in the same RAM 7 and set in the sequencer 22 ( Step Sb4).

  Next, the user specifies an effect (step Sb5). That is, when the user performs a predetermined key operation on the portable terminal device 1, a list of effect programs stored in the effect program area of the RAM 7 is displayed on the display. When the user selects an effect program from the displayed list, the effect program selected by the user is read from the effect program area of the RAM 7, and is set in the execution data area in the RAM 7, and the effect program is stored in the DSP 16 (Step Sb6). If an effect program is attached to the incoming melody set in step Sb4, step Sb6 is executed even if the user does not specify the effect in step Sb5, and the effect program attached to the incoming melody is stored in RAM7. It is set in the execution data area and loaded into the DSP 16.

  Next, the user specifies an effect parameter using the operation keys of the mobile terminal device 1 (step Sb7). When this designation is made, the designated effect parameters are written in the execution data area of the RAM 7, and then set in the DSP 16 (step Sb8). Next, the user specifies reproduction confirmation using the operation keys (step Sb9). When this designation is made, the sequencer 22 sequentially outputs the incoming melody data currently set therein to the sound source 15. Thereby, the effect set by the user is added to the incoming melody set by the user, and sound is output from the speaker 26. The user can check the effect or the like by hearing this (step Sb10).

  If the result of the check is not "OK" (step Sb11 is "NO"), any of the above-described steps Sb1, Sb3, Sb5 and Sb7 is re-designated. If "OK" (step Sb11 is "YES"), setting registration for incoming call is performed (step Sb12). Thereby, at the time of an incoming call, an incoming melody can be generated based on the above-described settings.

  Next, a case where the user specifies a conversation voice in step Sb1 will be described. In this case, the user next specifies an effect program (step Sb5). The specified effect program is set in the execution data area of the RAM 7, and then loaded into the DSP 16 (step Sb6). Next, the user specifies an effect parameter (step Sb7). When this designation is made, the designated effect parameters are written in the execution data area of the RAM 7, and then set in the DSP 16 (step Sb8). Next, the user specifies reproduction confirmation using the operation keys (step Sb9), and then speaks toward the microphone 13 to confirm the effect (step Sb10).

  In this embodiment, the incoming melody and the effect program selected by the user are set in the execution data area of the RAM 7. However, instead of this, the incoming melody area and the effect program area in the RAM 7 are stored. The selected data and program may be marked.

(3) Incoming call processing: FIG.
Next, an operation when there is an incoming call to the portable terminal device 1 will be described. When the portable terminal device 1 receives a call, first, the selector 23 selects the output of the sound source 15. Next, the music data of the incoming melody in the execution data area of the RAM 7 is loaded into the sequencer 22 (step Sc1). Next, the effect program and the effect parameters are read from the execution data area of the RAM 7 and set in the DSP 16 (step Sc2). Then, a start command is output to the sequencer 22 (step Sc3). When this start command is output to the sequencer 22, the incoming melody is reproduced thereafter (step Sc4).

  That is, the sequencer 22 sequentially outputs the music data of the incoming melody loaded in step Sc1 to the sound source 15. The sound source 15 forms a tone signal corresponding to the input music data, and outputs it to the effector 24 via the selector 23. The effector 24 applies an effect to the tone signal of the sound source 15 based on the effect program 25 set in step Sc2, and outputs the signal to the speaker 26. As a result, an incoming melody is generated from the speaker 26.

  When the reproduction process of the music data set in the sequencer 22 is completed, it is determined whether or not the music data is to be repeatedly reproduced (step Sc5). If the result of the determination is “YES”, then an end command is issued. It is checked (step Sc6), and if the end command has not been output, the incoming melody is reproduced again (step Sc4). On the other hand, if the result of the determination in step Sc5 is [NO], or if the result of the determination in step Sc6 is "NO", the ringing melody reproduction process ends.

(4) Processing at the time of making a call Next, an operation when the user of the portable terminal device 1 makes a call will be described.
When the user inputs the telephone number of the other party using the numeric keypad of the mobile terminal device 1 and then turns on the off-hook key, first, the selector 23 is switched, and the output of the voice CODEC 11 is supplied to the effector 24 via the selector 23. You. Next, an audio conversion effect program and parameters are read from the execution data area of the RAM 7 and set in the DSP 16.

  Next, the destination telephone number is transmitted from the communication unit 9 to the base station. Then, after the line connection with the other party is made, a call is made by the microphone 13 and the speaker 12 thereafter. At the time of this call, when the user inputs a voice from the microphone 13, the input voice is converted into a voice signal by the microphone 13, converted into digital voice data in the voice CODEC 11, and supplied to the effector 24 via the selector 23. . The effector 24 applies an effect to the audio data, and outputs the audio data to the audio CODEC 11. The audio CODEC 11 compresses the audio data to which the effect has been added, and outputs the compressed audio data to the communication unit 9. The communication unit 9 transmits the compressed audio data from the antenna 10.

Note that the user can leave only the favorite incoming melody in the music data area of the RAM 7 and delete other music data. Similarly, it is possible to leave only the favorite effect program in the effect program area of the RAM 7 and delete other effect programs. Thereby, the area of the preset effect program in the terminal device can be reduced.
Further, in the above embodiment, an effect is applied to a ringtone melody and a voice. However, the present invention applies an effect to the output of the sound source when the terminal device has a sound source for music reproduction. It is of course possible to do so.
In the above embodiment, the sound source 15 and the sequencer 22 may be formed by software processing by a DSP (CPU) or may be formed by hardware.
