The 32 words are music data of a part of one music piece, and are set as the head music data. The musical score data written in the FIFO 31 is composed of note data and rest data, and an example of the data configuration is shown in FIG. 1 shown in FIG.
The word note data is composed of octave chords and note chords, part numbers to which the note data belongs, intervals that are the time lengths until the next note or rest, and note length information. The one-word rest data shown in FIG. 4 includes rest data indicating the type of rest, a part number to which the rest data belongs, and an interval that is the time length until the next note or rest. Have been.

When the tone generator 35 reproduces a musical sound, the FI
The above-mentioned note data and rest data are sequentially read from the FO 31, and the FIFO
An empty area is generated in O31. FIFO
Since only the first 32 words of the musical score data are written in the musical score data 31, if the next musical score data following the generated empty area is written, the musical score data for reproducing the high quality musical tone whose data amount is increased. However, by repeatedly writing the musical score data successively to the FIFO 31, high-quality musical score data can be written and reproduced. The music reproducing apparatus of the present invention reproduces music data based on such a principle.
The number of empty areas in the FO 31 when the next musical score data is written to the FIFO 31 is set. The IRQ Point data is data for giving an interrupt request signal (IRQ) to the system CPU 10 for instructing writing of the musical score data following the FIFO 31 when an empty area corresponding to the word indicated by the data is generated, and prior to reproduction. IRQ Point data is set. In this case, I
When the RQ Point data is set close to 0 words, the interrupt frequency increases, but the number of write words decreases, so that the processing of the system CPU 10 can be light. On the other hand, if IRQ Point data is set close to 32 words,
Although the frequency of interruption is reduced, the number of words to be written is increased, so that the processing of the system CPU 10 becomes heavy. Therefore, it is preferable to set the IRQ Point data according to the processing speed of the system CPU 10.

Here, when a start instruction for reproducing music data is given to the music reproducing unit 15, the sequencer 33
A read pulse (Read) is applied to O33 and the FIFO 31
When the score data is note data, the pitch data of the octave code and note code in the score data, the part designation information, and the key-on are read at the timing based on the set tempo information and interval information. The instruction data is set in the sound source unit 35. The tone generator 35 generates a musical tone having a designated pitch based on the tone color parameters set for the designated part from these data set in the tone generator register. Then, at the timing when the note length of the note data has elapsed, the sequencer 33 sets the key-off data of the musical tone in the tone generator 35 by designating the part. Thereby, the sound source unit 35 performs a silencing process of the musical sound. By executing such a process each time the musical score data is read out from the FIFO 31, the tone signal reproduced from the sound source unit 35 is output to the DAC 36.

Then, with the progress of the tone reproduction, FIFO3
When the empty area detected in 1 becomes equal to the IRQ Point data value, an interrupt request signal (IRQ) is given to the system CPU 10. In response to this, the system CPU 10 reads the next musical score data from the system RAM 11 by (31-IRQ Point) words and sends it to the bus 24. This musical score data is written to an empty area of the FIFO 31 via the interface 30. By repeatedly executing such a process of writing the next musical score data for (31-IRQ Point) words into the FIFO 31, even if the musical score data is composed of many data, all the data are eventually stored in the FIFO 31. Is written. Since the musical score data read out from the FIFO 31 is reproduced and output in accordance with the tempo in the sound source section 35, music data capable of obtaining high-quality reproduced musical sound, which is a large amount of data, is stored in, for example, 32 words. Even if the FIFO 31 that can only store the data is used, the data can be reproduced.

If the music playback unit 15 is set to play a music when the mobile phone 1 receives a call, the above-described music is received when the mobile phone 1 receives a call. The tone signal output from the DAC 36 after the reproduction process is performed is emitted from the speaker 23 as a ring tone.
When the mobile phone 1 is put on hold, the music playing unit 15
Is set so that the music is reproduced as a holding tone, the music signal output from the DAC 36 by performing the above-described music playing process when the mobile phone 1 is put on hold is output as a holding tone to the speaker 22. Sound is emitted from. at the same time,
A tone signal output from the sound source unit 35 for transmitting the hold tone to the other party's telephone is supplied to the audio processing unit 14,
The data is transmitted via the communication unit 13.

Next, the detailed configuration of the FIFO 31 is shown in FIG. 7, and its operation will be described with reference to FIG. When IRQ Point data is output from the interface 30,
The latch pulse (LP) is supplied from the INDEX decoder 32 to the latch circuit 43. Thereby, the latch circuit 4

The data will be latched. When the musical score data is output from the interface 30, INDEX
A write pulse (WP) is applied from the decoder 32 to the up terminals of the write address counter 41 and the up / down counter 45. The write pulse (WP) is generated for each word, and in the initial state, the write pulse (W
Since the write address counter 41 is sequentially incremented from "0" to "31" by P), the first musical score data of 32 words is stored in the RAM 40 having at least a 32-word storage capacity. At the same time, the up / down counter 45 also counts up from "0" to "31". This state is shown as the start of FIG. 8A, and the RAM 40 is in the state “FULL”, the address of the write address W is “31”, and the address of the read address R is “0”. You.

The data is written from address “0” to address “15”, which is an empty area of M40.
2 and the write pulse (WP) is applied to the write address counter 41.
And applied to the up terminal of the up / down counter 45. The write pulse (WP) is 16 words, 16
A pulse is generated, and the write address counter 41 which counts the modulo 31 by this write pulse (WP) is "
The score data is incremented to the address of 15 ", and the musical score data is written to the address. At the same time, the up / down counter 45 is also incremented by" 16 ". Even at this time, the musical score data is sequentially read out. Up /
Since the down counter 45 is down-counted by the read pulse (Read), the count value is a cumulative value of the write pulse (WP) and the read pulse (Read). RAM 40 supplemented with score data of 16 words
FIG. 8C shows the state at the time of additional writing of 16 words (supplement of musical score data) in FIG.

Next, a read pulse (Read) is applied to the read address counter 42 from the sequencer 33, and the musical score data is read from the RAM 40 for 32 words.
The state of the AM 40 is shown in FIG. Since the read address counter 42 also counts modulo 31, the read address counter 42 in this state
Has returned to the address "0". At this time, the count value of the up / down counter 45 becomes "15" again, so that the interrupt request signal (IRQ) is again output from the comparison circuit 44 and given to the system CPU 10, and the above-described processing is repeated. That is, the musical score data for the next 16 words is converted from the address “16” of the RAM 40 to “31”.
Each address is written. FIG. 8E shows the state of the RAM 40 in which the musical score data is further supplemented by 16 words and the musical score data of a total of 32 words is additionally written.

As described above, every time a free area of 16 words is generated in the RAM 40, the musical score data of 16 words is additionally written and supplemented to the RAM 40 sequentially, so that the storage capacity of the RAM 40 is at least 32 words. For example, music data having a large amount of musical score data from which high-quality reproduced musical tones can be obtained can be sequentially written to the RAM 40 and reproduced. In addition, up /
The count value of the down counter 45 matches the number of words of the musical score data stored without being read from the RAM 40 yet.

By the way, each part is set to the tone assigned according to the tone assignment data at the time of reproduction. However, if the tone color assignment data for each part is inserted into the musical score data, the tone is assigned during reproduction. This tone assignment data is
When read from O31, the sequencer 33 stores the timbre number of the timbre assignment data in the timbre data storage unit (Voice
RAM) 34. In this case, the timbre data storage unit (V
Tone data for eight tones, which is larger than the number of parts, is written in the oice RAM) 34. The tone color of each part can be set to any of the eight tone colors. Thereby, the timbre parameter corresponding to the timbre number is read from the timbre data storage unit (Voice RAM) 34 and
5 is set in the tone generator register for the part specified by the tone color assignment data. Therefore, the tone color of the musical tone of the part reproduced by the sound source unit 35 is changed during reproduction.

As described above, by inserting the tone color assignment data for each part into the musical score data, the tone color of each part can be arbitrarily changed during the reproduction. A tone data storage unit (Voice RAM) 34
The user can select the timbre data of eight timbres stored in the RAM from the timbre data stored in the system RAM 11 and transfer the timbre data to the timbre data storage unit (Voice RAM) 34. At this time, the system RAM 11 Since a large number of various tone data have been downloaded from the download center 6 and the external device 20, the tone data storage unit (Voice RAM) 34 selects arbitrary tone data from the large variety of tone data. Can be memorized.

Next, at the time of music reproduction processing, the system CPU 1
FIG. 9 is a flowchart of the music reproduction assisting process executed by the program 0.
Shown in When the music playback mode is set, a music playback menu is displayed on the display unit 18, and a desired music selection operation is performed by operating a dial button or the like from the music selection menu displayed on the display unit 18 in step S1. The music selection at this time is performed by the system R
One of the music data stored in the AM 11 and the system ROM 12 is selected. In this case, the download RAM 6 and the external device 20 are stored in the system RAM 11.
The music data downloaded from is stored.
When the music selection operation is completed, the timbre data and the tempo are set in step S2. In this step S2, the timbre data of the eight timbres in the tuned music data is reproduced by the tune reproduction unit 1.
And transferred to the tone color data storage unit (Voice RAM) 34.
Is stored. Further, the tempo data in the selected music data is transferred to the music reproducing unit 15 and the sequencer 3
The tempo data displayed on the display unit 18 at this time may be edited by operating a dial button or the like.

Next, in step S3, the IRQ Point data displayed on the display unit 18 is set to a predetermined value by operating a dial button or the like. At this time, the system C
The IRQ Point data is set in consideration of the processing speed of the PU 10. Next, the score data of 32 words in the selected song data is read from the system RAM 11, transferred to the song reproducing unit 15, and written into the FIFO 31, so that the FIFO 31 is FULL with the score data.
State. Next, the process waits until a start operation is performed in step S5. In the case of reproducing as a ringtone, the start operation is performed when a call is received, and when the reproduction is performed as a hold sound, the start operation is performed by operating a hold button. Here, if it is determined in step S5 that the start operation has been performed, step S6
Then, the start command is transferred to the music reproducing unit 15.

If it is not determined that the start operation has been performed, the flow branches to step S11 to determine whether or not the reproduction operation button has been operated. When it is determined that the reproduction operation button has been operated, the process returns to step S1 and the operations of steps S1 to S4 can be executed again. If it is not determined that the reproduction operation button has been operated, the process returns to step S5 and waits until a start operation is performed. When the music reproducing unit 15 receives the start command, the above-described music reproducing process is started, and the selected music is reproduced. Then, the music reproducing unit 15
If it is determined in step S7 that an interrupt request signal (IRQ) has been generated in step S7, in step S8 (31-IRQ Po
int) Score data with the number of words is stored in the system RAM 11
And transfers it to the music reproducing unit 15. The processes in steps S7 and S8 are repeatedly executed until it is determined in step S9 that the stop operation has been performed. When the stop operation is performed as a ringtone, the operation of the incoming call button is a stop operation, and when the reproduction is performed as a hold sound, the operation of the hold release button is a stop operation. Here, it is determined that the stop operation has been performed in step S9.
If the judgment is made in step S10, the process proceeds to step S10, where the stop command is transferred to the music reproduction unit 15, and the music reproduction unit 1
The music reproduction processing in 5 is stopped. At the same time, the process returns to step S5 and waits until the start operation is performed again.

As described above, the music selected by executing the music reproduction processing is reproduced when a call is received when the music is reproduced as a ring tone, and the hold button is reproduced when the music is reproduced as a hold sound. This is the time when the operation is performed, and the music reproduced in that case is the music selected by the music selection operation. In addition, in the music selection operation, the music to be reproduced as the ringtone and the hold sound may be independently selected, so that the independent music can be reproduced when each start operation is performed. In addition, since the music selection operation can be performed at any time, it is possible to arbitrarily select the music to be reproduced as the ringtone or the hold sound.

The main processing of the system CPU 10 is to execute telephone function processing (not shown).
Even if the music reproduction auxiliary processing shown in FIG. 9 is executed together, the music reproduction auxiliary processing is a light processing.
The need for a high-speed CPU as the system CPU 10 can be eliminated. The storage capacity of the FIFO 40 is 3
Although the capacity is such that the musical score data for two words can be stored, the present invention is not limited to this, and the storage capacity may be much smaller than that of the system RAM 11. Furthermore, the storage capacity of the timbre data storage unit (Voice RAM) 34 is a storage capacity capable of storing timbre data for eight timbres, but the present invention is not limited to this. The storage capacity may be significantly smaller than the system RAM 11.

The sound source section 35 in the music reproducing section 15 described above can be constituted by a frequency modulation type sound source, that is, an FM sound source. The FM sound source utilizes harmonics generated by frequency modulation for synthesis of musical tones, and can generate a waveform having harmonic components including non-harmonic sounds with a relatively simple circuit. The FM sound source can generate a wide range of musical sounds from synthetic sounds of natural musical instruments to electronic sounds, and an example of the configuration is shown in FIG. The FM sound source uses an oscillator called an operator that oscillates a sine wave equivalently. An FM sound source 50 configured by cascading operators 1 and 2 as shown in FIG. By supplying the oscillated sine wave as a modulation signal to the operator 2, the operator 2 generates a frequency modulation wave FM (t). Thus, the operator 1 is called a modulator 51 because it generates a modulation signal, and the operator 2 is called a carrier 52 because it generates a carrier. Operator 1
And the operator 2 have the same configuration.

[0045] In the modulator 51, the pitch data that changes in a sawtooth-shaped inclined corresponding to the input phase angle data omega _m is outputted from the pitch generator 51c, the pitch data and the input modulated data "0" is added It is added by the unit 51a. The output of the adder 51a is a sine wave generator 51
The sine wave generator 51b generates a sine wave having a frequency corresponding to the rate of change of the pitch data by reading the sine wave table based on the sawtooth-changed pitch data supplied from the adder 51a. You. The amplitude of this sine wave is controlled by amplitude data B generated from the envelope generator 51d. Therefore, the sine wave output from the sine wave generator 51b is Bsin ω _m t
Can be expressed as

[0046] Further, in the carrier 52, sine the pitch data that changes in a sawtooth-shaped inclined corresponding to the input phase angle data omega _c is output from the pitch generator 52c, which is output from the pitch data and the modulator 51 The modulated signal, which is a wave, is added by the adder 52a. Adder 5
The output of 2a is supplied to a sine wave generator 52b, and by reading a sine wave table based on the addition data output from the adder 52a, the sine wave changed according to the change rate of the addition data is obtained. Generated from. The amplitude of the sine wave is controlled by amplitude data A generated from the envelope generator 52d. Therefore, the sine wave output from the sine wave generator 52b is A
so expressed as _{sin (ω c t + Bsinω m} t).
As described above, the output FM (t) from the carrier 52 is frequency-modulated, and the above expression is a basic expression of the FM sound source 50.

Further, as shown in FIG.
Since the configuration of 1 and the carrier 52 is the same, a frequency-modulated wave can be generated even if the output of the carrier is fed back and input. Such an FM sound source is called a feedback FM sound source, and a configuration example thereof is shown in FIG. As shown in FIG. 11, the feedback FM sound source 60
Is composed of an operator 61 and a feedback circuit 62. In the operator 61, the pitch data that changes sawtooth slope corresponding to the input phase angle data omega _m is outputted from the pitch generator 61c, the pitch data and the input modulated data "0" and the feedback circuit 62 Is added by the adder 61a. Adder 6
The output of 1a is supplied to a sine wave generator 61b, and the sine wave table 61b is read out from the addition data output from the adder 61a. Generated from. The amplitude of the sine wave is controlled by amplitude data B generated from the envelope generator 61d. The output of the sine wave generator 61b is controlled in the feedback circuit 62 so as to obtain the feedback ratio β, and is input to the adder 61a as a modulation signal. As a result, the frequency-modulated output FM (t) is output from the sine wave generator 61b.

The feedback FM tone generator 60 can be an FM tone generator suitable for generating a string-based tone. As described above, in the FM sound sources 50 and 60, musical tones of different timbres can be generated by changing the manner of connection of the operator in units of the operator, and the manner of connection of the operator is called an algorithm. In the above-described FM sound source, the timbre can be changed by controlling the pitch data output from the pitch generator and changing in the amplitude output from the envelope generator, or by changing the algorithm. The tone data for obtaining a desired tone in the FM tone generator is composed of modulator tone data and carrier tone data, and the amount of tone data for one tone is much smaller than the amount of tone data of the waveform memory tone generator. Quantity.

Here, FIG. 12 shows an example of the configuration of the timbre data for eight timbres written in the timbre data storage unit (Voice RAM) 34 when the sound source unit 35 is constituted by the FM sound source. The timbre data for eight timbres, timbre 1, timbre 2,..., Timbre 8, written in the timbre data storage unit (Voice RAM) 34 are composed of modulator timbre data and carrier timbre data, respectively. The modulator timbre data and the carrier timbre data have the same data format, and the data format is shown in FIG. As shown in FIG. 13, the tone color data for modulator and the tone color data for carrier are, for example, 3-bit multiple setting data (ML2-ML0), 1-bit vibrato ON / OFF data (VIB), and 1-bit envelope waveform. Type data (EGT), 1-bit sustain ON / OFF data (SUS), 4-bit attack rate setting data (AR3-AR0), 4-bit decay rate setting data (DR3-DR0), 4-bit sustain Level setting data (SL3-SL
0) 4-bit release rate setting data (RR3-
RR0), 1-bit waveform selection data (WAV), 3-bit feedback amount setting data (FL2-FL)
0), 6-bit total level data (TL5-TL
0) consists of 32-bit data.

Multiple setting data (ML2-ML0)
Is data for setting the oscillation frequency magnification, and the pitch generator outputs pitch data of a change rate multiplied by the magnification indicated by the multiple setting data. The multiple setting data can set a magnification of, for example, ± 0.5 to ± 7. When the multiple setting data is used in the modulator 51, the frequency of the modulation signal is changed, and the timbre can be changed. Also, vibrato ON /
The OFF data (VIB) is data for setting whether or not to apply vibrato. Further, the type data (EGT) of the envelope waveform is data for setting whether the envelope waveform is an envelope of a sustained sound or an envelope of an attenuated sound. Furthermore, Sustain ON / OFF
When the data (SUS) is set to ON, the release rate switches to a release rate with a fixed gentle slope at the timing when the tone length ends, and when the data (SUS) is set to OFF, the tone ends when the tone length ends. Then, the set release rate is reached.

Attack rate setting data (AR3-AR
0) is data for setting the time from the start of sound generation until the maximum volume is reached, for example, from 0.0 ms to 3 ms.
The time can be set within 8.1 seconds. In addition, the decay rate setting data (DR3
-DR0) is data for setting the decay time from when the volume reaches the maximum level to when the level reaches the sustain level. For example, the decay time can be set between 4.47 ms and 73.2 sec. Further, the sustain level setting data (SL3-SL0) is data for setting a continuous level when the envelope waveform is set as a continuous sound by the envelope waveform type data (EGT).

Further, the release rate setting data (RR3-RR0) is data for setting the decay time from the sustain level to the sounding length end timing in the case of the decay sound. It becomes attenuated at a predetermined steep inclination. In the case of a sustained sound, the data sets the speed of decay from the sounding end timing, and is represented by a decay time from a level of 0 dB to -48 dB.
It can be set between 47 ms and 73.2 sec. Furthermore, the waveform selection data (WAV) is data for setting whether the waveform generated by the sine wave generator is a sine wave or a half-wave rectified sine wave. Further, the feedback amount setting data (FL2-FL0)
Is data for setting a feedback rate in the feedback FM sound source shown in FIG. 11, and is valid only for a carrier operator. Setting this data in a carrier is suitable for generating a string-based tone. The feedback amount setting data is, for example, data represented by a time of 0 to 4π. Furthermore, the total level data (TL5-TL0) is data for setting the overall volume.

As described above, when the sound source section 35 is constituted by an FM sound source, only (32 × 32 × 32 bits) of modulator timbre data of 32 bits and carrier timbre data of 32 bits, for example. 2) It becomes possible to compose tone data for one tone by bits. Therefore, if the sound source unit 35 is an FM sound source,
The data amount of eight timbres stored in the timbre data storage unit (Voice RAM) 34 is 8 × (32 × 2) bits, that is, 6
It can be 4 bytes, and the timbre data storage unit (Voice
RAM) 34 can be reduced in storage capacity. Furthermore, even if the transfer speed of the timbre data transferred to the timbre data storage unit (Voice RAM) 34 is low, the amount of timbre data for eight timbres is small, so that the timbre data can be transferred in a sufficiently short time. As a result, even when the calculation speed of the CPU 10 is low, it is possible to reproduce high-quality music of various timbres. Further, when the timbre data is downloaded from the download center 6, the timbre data can be downloaded in a short time because the amount of timbre data for one timbre is small. Note that the amount of timbre data for one tone in a waveform memory sound source (PCM sound source) may reach several kilobytes, and when an FM sound source is used, the amount of timbre data for one tone is compared with the amount of timbre data in the waveform memory sound source. A very small amount of data can be obtained.

Further, as the sound source system of the sound source section 35 in the music reproducing apparatus of the present invention, the FM sound source system has been described, but the present invention is not limited to this.
Sound source) method, physical model sound source method, etc.
The configuration of the sound source may be a hardware sound source using a DSP or the like, or a software sound source that executes a sound source program. Furthermore, the musical score data is in the format shown in FIG. 4, but the present invention is not limited to this format, and MIDI format with time information added or SMF (Standard MIDIF
ile) format.

[0055]

As described above, according to the present invention, the tone color data transferred via the interface means is stored in the tone color data storage means having a capacity capable of storing limited kinds of tone color data. Therefore, even if the storage capacity of the timbre data storage means is small, the parameters in the timbre data can be set to a data amount sufficient to obtain a high-quality timbre. As a result, it is possible to reproduce a musical piece having a high tone quality. Also, from the many tone data stored in the storage means provided outside the music playback means, only the tone data required for playing the music is transferred to the music playback means and stored in the tone data storage means. Therefore, various types of timbre data can be selected as the timbre of the reproduced music even if the storage capacity of the timbre data storage means is small. further,
By downloading the timbre data to the external storage means through the communication line, the selection range of the timbre data can be further increased.

Furthermore, the arithmetic processing means only needs to read out the necessary timbre data from the timbre data storage means and send it to the music reproduction means, and does not need to perform the music reproduction processing. Even so, high quality music can be played. Furthermore, if the sound source means of the music reproducing means provided in the telephone terminal device is of a frequency modulation type, the tone modulation data amount of the frequency modulation type sound source means is much larger than that of the waveform memory sound source (PCM sound source) type. Can be reduced. This makes it possible to provide a telephone terminal device that can reproduce high-quality music of various timbres even if the speed of the transmission path for transmitting timbre data is low due to the low calculation speed of the arithmetic processing means. Furthermore, since the amount of timbre data is small, it is possible to store timbre data that can reproduce high-quality timbre music even if the capacity of the timbre data storage means is smaller. Also, when downloading timbre data from the download center, the timbre data can be downloaded in a short time because the amount of timbre data for one timbre is small.
