Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device that allows a user to compose music to be reproduced at the time of an incoming call or the like.

[0002]

In a recent portable telephone device, for example, even in a place where there are many people, a ring tone is used as a ring tone in order to easily notify that the incoming call was in the portable telephone device owned by the user. Many of them have a function of registering a plurality of melodies to be played in advance and selecting them from among them, or having a function of inputting the melodies by performing key operations by themselves.

[0003] In such a portable telephone device, when a melody is created as a ringtone, "1" to "7" of ten keys are used.
The keys up to correspond to the seven pitches (note names) from C (C) to C (B), and the lengths of the chromatic symbols such as sharp (#) and flat, and quarter notes and eighth notes are It is common to separately correspond to other keys.

However, such a correspondence between a pitch and a key is an idea close to a feeling of creating a computer program or the like, and is far from a feeling of creating a music. This makes it difficult to create.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a portable telephone device that can more easily create music such as a ringtone.

[0006]

According to the portable telephone device of the present invention, when the user creates a music piece, the music piece creation control means sets one of the 12 matrix keys within one octave. In this example, the twelve chromatic pitches existing in the octave above the lowest note (excluding the note one octave above) are associated with each other so that their pitch order matches the arrangement order of the matrix keys. That is, the 12 chromatic pitches correspond to the 12 matrix keys in a one-to-one correspondence, and the intervals (degrees) of each pitch correspond to the matrix key arrangement intervals, resulting in an arrangement close to the image of a keyboard. Therefore, the user can create music more easily than before.

According to the second aspect of the present invention, when the user turns on any one of the matrix keys at the time of creating a music, the music creation control means changes the pitch corresponding to the key to the ON operation time. For the duration. That is, in the conventional mobile phone device, the composition of music is performed in non-real time, so even if a key is turned on at the time of composition of music, the musical tone of the musical pitch is constant to present the corresponding musical pitch. It only sounded for hours.

On the other hand, according to the present invention, while any one of the matrix keys is turned on, a musical tone having a pitch corresponding to the key is emitted, so that the user can turn on and off the matrix key. It is possible to play a melody or the like in real time as if playing a musical instrument.

According to the third aspect of the present invention, the music composition control means can shift the range of the chromatic pitch corresponding to the matrix key in advance. In other words, there are some songs that cannot be played within one octave from standard C (C4) to C (B4), for example, so that the range corresponding to the matrix key is shifted to provide an auxiliary key for changing the octave. It is possible to easily cope with the performance of such music by turning on each key as much as possible without simultaneously operating such music.

According to the fourth aspect of the present invention, the music composition control means shifts the range of the chromatic pitch corresponding to the matrix key in units of rows or columns of the matrix key arrangement. With such a configuration, even when the tone range is shifted in advance, the positional relationship between the pitches is not changed fundamentally and is shifted, for example, by one line or one column, so that the user can operate the key without being confused. You can perform.

According to the portable telephone device of the present invention, the music composition control means assigns a musical scale to a part of the operation keys, sets at least one other operation key to a semitone control key, When any one of the operation keys is turned on, a pitch corresponding to the key is emitted during the on-operation time. When the user simultaneously turns on one of the operation keys and the semitone control key, the pitch corresponding to the operation key is changed by a semitone to sound.
Accordingly, the user can make a musical tone generated in real time while changing the pitch assigned to the operation key by a semitone as necessary, so that the music can be easily created.

According to the portable telephone device of the present invention, the music composition control means includes, as semitone control keys, a semitone up control key for raising the pitch by a semitone by an ON operation, and a semitone lowering control key for lowering the pitch by a semitone. Are set.
Therefore, the user can perform the operation of changing the pitch by a semitone more flexibly.

According to the portable telephone device of the present invention, the music composition control means assigns at least seven major musical intervals from "do" to "shi" to a part of the operation keys. The range can be covered. According to the portable telephone device of the present invention, since the seven major scale intervals are assigned to the seven numeric keys from "1" to "7", the user can determine the correspondence between the scale intervals and the numeric keys. It can be easily grasped.

According to the portable telephone device of the ninth aspect, the music composition control means further includes three numeric keys from "8" to "0" and three numeric keys from "1" to "3". Assigns a pitch that is one octave higher than the pitch between “do” and “mi” assigned to the number keys, so that the range that can be pronounced in real time is expanded while the pitches correspond to the number keys. Can be.

Further, according to the portable telephone device of the tenth aspect, the music composition control means further comprises "8", "9",
One octave for the scale intervals from "do" to "so" assigned to the five numeric keys from "1" to "5" for each of the operation keys "*", "0", and "#" Since a higher pitch is assigned, the range of sounds that can be pronounced in real time can be further expanded.

According to the portable telephone device of the eleventh aspect,
The music composition control means makes it possible to produce music in real time by storing in the storage means data generated when each of the matrix keys is turned on / off in real time by the user.

That is, as described above, there are provided twelve keys corresponding to the twelve chromatic scales one-to-one, and when any one of them is turned on, a musical tone of the corresponding pitch is generated. Thus, the user can play a melody or the like in real time. Then, the music creation control means stores data generated based on the on / off of each key operated at that time in the storage means, so that by performing reproduction based on the data stored in the storage means,
Music created in real time will be played.

According to the portable telephone device of the twelfth aspect,
The musical composition creation control means enables a range of a chromatic pitch corresponding to a matrix key to be shiftable in advance.
According to the above described cellular phone device, the range of the chromatic pitch corresponding to the matrix key is shifted in units of rows or columns of the arrangement of the matrix keys. Therefore, the same effect as in the third or fourth aspect can be obtained even when a music is created by real-time input.

According to the portable telephone device of the present invention,
When the user turns on any one of the operation keys, the musical composition creation control means causes a musical interval corresponding to the key to be sounded for the on-operation time, and the user operates any of the operation keys and the semitone control key. Simultaneously, when the on operation is performed, the pitch corresponding to the operation key is changed by a semitone to sound. Then, by storing data generated based on real-time on / off operation of the operation keys and the semitone control keys by the user in the storage means, it is possible to create music in real time.

Therefore, by performing the same key operation as in claim 5, it is possible to create a music in real time and store the data in the same manner as in claim 11, and to play the created music as needed. .

According to a fifteenth aspect of the present invention, the music composition control means includes, as semitone control keys, a semitone up control key for raising the pitch by a semitone by an on operation, and a semitone lowering control for lowering the pitch by a semitone. Since two keys are set, the same effect as that of the sixth aspect can be obtained.

Further, according to the portable telephone device of the present invention, the music composition control means assigns at least seven major scale intervals from "do" to "shi" to a part of the operation keys. According to the described mobile phone device, those 7
One major scale interval is assigned to seven numeric keys from “1” to “7”. Therefore, the same effects as those of the seventh and eighth aspects can be obtained.

Further, according to the portable telephone device of the eighteenth aspect, the music composition control means can control the number of music pieces from "8" to "0".
20. A scale pitch one octave higher than a scale pitch from "do" to "mi" assigned to three numeric keys from "1" to "3" to the three numeric keys, and According to the mobile phone device described above, the music composition control unit assigns five operation keys from “1” to “5” to the operation keys “8”, “9”, “*”, “0”, and “#”. A scale pitch one octave higher is assigned to the scale pitches “do” to “so” assigned to the number keys. Therefore, the same effects as in the ninth and tenth aspects can be obtained.

According to the portable telephone device of the present invention,
The metronome means, when the user creates a song,
Since the guide light is emitted based on the set time signature and tempo, the user can check the light emission of the guide light and take the time signature and tempo at the time of input, thereby making music composition in real time easier. Can be.

According to the portable telephone device of the twenty-first aspect,
Since the metronome means also emits a guide sound based on the set time signature and tempo, the user can take the time signature and tempo at the time of input while listening to the guide sound.

According to the portable telephone device of the present invention,
Music creation control means, based on the tempo of the music set by the user and the key ON operation time by the user,
Automatically optimizes the rhythm of each input sound. That is,
When the tempo of the music is determined, the time corresponding to the length of the quarter note or eighth note is determined accordingly. And the on / off time of each key operated by the user in real time is
They do not always match them.

Therefore, the music production control means determines which of the rhythms, such as quarter notes and eighth notes, is closest to each set on-operation time with respect to the set tempo, and automatically optimizes it. This allows the user to more easily create music.

According to the portable telephone device of the twenty-third aspect,
The music composition control means is capable of setting a resolution for performing optimization. That is, the minimum unit of the rhythm may be, for example, up to eighth notes, depending on the music that the user intends to create. Therefore, if the music composition control means optimizes the rhythm with a resolution exceeding the minimum unit in response to the user's input operation, for example, it is intended to input an eighth note.
It may be judged as a minute note, which may hinder music composition.

Therefore, it is possible to avoid inputting a detailed rhythm unnecessarily by presetting the resolution at the time of optimization to an eighth note, a sixteenth note, or the like in accordance with the music or the like. Creation can be performed more efficiently.

According to the portable telephone device described in claim 24,
Since the music creation control means can independently correct each sound of the performance part in which the music is created in real time, even if input fails in music creation in real time,
An arbitrary sound can be specified and corrected, and the degree of music completion can be enhanced.

According to the portable telephone device of the twenty-fifth aspect,
Since the music creation control means can input a plurality of performance parts independently, based on the performance data created by the music, it is possible to reproduce in a multi-part by a music sound generation means capable of simultaneously producing a plurality of music sounds, Various performances (playback)
Can be performed.

[0032] According to the portable telephone device of the twenty-sixth aspect,
When the user creates a music piece for a new performance part, the music piece creation control means controls the music sound generation means to reproduce the other music piece parts for which the music piece has already been created as necessary. Therefore, the user can create a new performance part in real time while listening to the performance part for which the music has been created, so that the time signature and tempo at the time of input can be more easily taken.

According to the portable telephone device of the twenty-seventh aspect,
Since the musical tone generating means can simultaneously produce a plurality of sounds in one performance part, for example, a chord can be sounded in the part performing the accompaniment of the main melody.

According to the portable telephone device of the twenty-eighth aspect,
Since the musical sound generating means can selectively reproduce a plurality of performance parts for which a musical piece has been created, for example, the reproduction of a part playing the main melody is stopped, and only the other accompaniment parts are reproduced, thereby corresponding to the main melody. The part also allows for a so-called karaoke-style play, such as a user playing in real time.

According to the portable telephone device described in claim 29,
The display music creation control means enables the created sound to be displayed in the form of a musical score on the display means when the user creates the music, so the user can express how the created sound is expressed on the music score. You can know whether it is.

According to the portable telephone device of the thirtieth aspect,
The display music creation control means enables the reproduced sound to be displayed in the form of a musical score on the display means even when the musical sound generation means reproduces the performance part for which the music was created.
The music to be played can also be viewed as a music score.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is a front view showing the appearance of the mobile phone device. FIG.
, A call start key, a call end key, a redial key,
Numeric keys from "0" to "9", * (asterisk) key,
A key operation unit (operation keys) including various keys such as a # (sharp) key and a scroll key, a microphone 4, a speaker 5, and a display unit (display means) 6 including an LCD for displaying telephone numbers and the like are provided. I have. A telescopic rod antenna (hereinafter simply referred to as an antenna) 7 is arranged on the upper surface of the housing 2. Note that, of the key operation unit 3, twelve keys obtained by adding a "*" key and a "#" key to ten numeric keys are referred to as matrix keys 3a.

FIG. 2 is a functional block diagram showing an electrical configuration of the mobile phone 1. In FIG. 2, the mobile phone device 1 mainly includes a control circuit (song creation control means, display control means) 8 including a microcomputer or the like, and the control circuit 8 includes an operation from the key operation unit 3. A signal is provided. Further, the control circuit 8 controls the display on the display unit 6.

When the audio signal input to the microphone 4 is supplied to the audio processing unit 9 and A / D converted, the data conversion unit 10 performs, for example, π / 4 shift DQPSK (Differe
ntial Quadrature (Phase Shift Keying) signal. Then, when the transmission data converted (digitally modulated) into the DQPSK signal is given to the transmission / reception unit 11, the transmission data is quadrature-modulated by, for example, an 800 MHz band carrier signal, and transmitted to the outside as a radio signal from the antenna 7. .

When the antenna 7 receives a radio signal, the received signal is transmitted to the transmitting / receiving unit 11 and the data converting unit 1.
The signal is demodulated at 0 and supplied to the audio processing unit 9. When D / A conversion is performed in the audio processing unit 9, the audio signal is output from the speaker 5 as an audio signal.

The control circuit 8 controls the audio processing unit 9, data conversion unit 10, and transmission / reception unit 11.
On the other hand, information such as detection of an incoming signal and a detected value of a transmission signal or a reception signal level is given from the transmission / reception unit 11 to the control circuit 8. The control circuit 8 includes a storage unit (storage means) 12 such as an EEPROM or the like.
Is connected, and the control circuit 8 writes and reads data to and from the storage unit 12 as necessary.

The musical sound processing section (musical sound producing means) 13
It comprises a P (Digital Signal Processor), a ROM, a RAM and the like. Waveform data for reproducing a musical tone is stored in the ROM in advance, and performance data of the musical tone is stored in the RAM (details will be described later). The DSP of the tone processing unit 13 processes the waveform data of the tone to be reproduced based on the performance data including the pitch and the rhythm, and when reproducing a plurality of tones simultaneously, adds a waveform obtained by adding the waveform data. The calculation is performed and output to the audio processing unit 9. The audio processing unit 9
The tone reproduction data provided by the tone processing unit 13 is converted into D / A
The data is converted and output from the speaker 5.

The LED 14 is, for example, as shown in FIG.
It is arranged on the back side of a transparent resin cover arranged near the base of the antenna 7 on the front side of the housing 2 or on the back side of the key operation unit 3. Turning on and off is controlled. These LEDs 14 normally blink when there is an incoming call. The key top of the key operation unit 3 is formed of a translucent resin or the like. When the LED 14 disposed on the back side of the key operation unit 3 is turned on, the light is visually recognized from the outside via the key top of the key operation unit 3. I can do it. The LED 14 has two colors, red and green.
Color emission is possible.

Next, the operation of the present embodiment will be described with reference to FIGS. When the user operates the key operation unit 3 to select a mode for creating a tune such as a ring tone, the control circuit 8 controls the twelve matrix keys 3a of the key operation unit 3 as shown in FIG. Each interval of 12 chromatic scales (chromatic scale) existing in the octave is assigned. The matrix keys 3a are arranged in 3 × 4 in the horizontal and vertical directions.
Is assigned so as to transit from “to (b)”.

That is, "1": "do", "2": "do #", "3": "re", ..., "0": "la #",
"#": Assigned as "S", and when the user turns on any one of the matrix keys 3a, a musical tone of the corresponding pitch is generated.

In the key operation section 3, the function key "F" functions as an upper octave key for raising the pitch by one octave, and the clear key "clear" functions as a lower octave key for lowering the pitch by one octave. . That is, if "1": "do" and "F" are simultaneously turned on, a sound of "do" that is one octave higher will be generated.

FIG. 3 is a flowchart showing the control contents of the music composition processing by the control circuit 8. First, the user operates the key operation unit 3 to set the number of quarter notes per minute for the music tempo (BPM (Beat Per Minut).
e)) (step A1). For example, if BPM = 60, 60 quarter notes are played per minute, and the length of the quarter note is 1 s.
Then, the control circuit 8 blinks the LED 14 in green at a time interval of one beat according to the set value of BPM (step A).
2) Act as a metronome for presenting a tempo to the user according to the blinking interval. That is, the control circuit 8 and the LED 14 constitute a metronome unit.

Subsequently, the user sets the time signature of the music, for example,
4/4, 3/4, etc. are set (step A3). Then, the control circuit 8 sets the LED 14 according to the set time signature.
Is changed (step A4). That is, the lighting color is set to red only for the first beat of the first bar. So, for example,
If the time is ／, the blinking pattern of the LED 14 is “red, green, green, red, green, green,...”, And if the time is ／, the blinking pattern is “red, green, green, green,. Red-green,
Green, green, ... ".

Next, if it is necessary to change in advance the range of, for example, standard C (C4) to C (B4) assigned to the matrix key 3a by default, the user sets the change ( Step A4a, A4
b). In other words, depending on the music, there is a case where the range to be used falls, for example, from S (G4) to D (C5) to F (F5). In such a case, the user often turns on the “F” key at the same time, and the key operation becomes troublesome.

Therefore, if the range assigned to the matrix key 3a is changed in order to correspond to the range of such music, only one key operation is required at all times, or the "F" key or the "F" key Simultaneous operation of the "clear" key can be minimized.

When the range is shifted as described above, the shift is performed in units of columns arranged in a matrix. That is, as shown in FIG. 14, the original "7", "8",
Fa #, Seo, Seo # arranged in the column of "9" are raised by two columns and changed to be assigned to the columns of "1", "2", and "3". Then, in the original columns of “7”, “8”, and “9”, de ↑ (C5), de # ↑ (C # 5), and de ↑ (D
5) are assigned, and the following columns of “*”, “0”, and “#” include the following information: ## (D # 5), M # (E5),
(F5) is assigned.

As described above, by shifting the range in units of the columns of the matrix arrangement, it is possible to minimize the change in the arrangement relationship between the intervals, and the user can perform key operations without feeling uncomfortable. is there. In FIGS. 1 and 14, the intervals corresponding to the key tops of the matrix keys 3a are shown for ease of understanding. However, when the interval is sometimes shifted as described above, FIG. 1
In some cases, it is better not to write the default pitch, such as

Next, the user sets the minimum resolution of the rhythm at the time of input (step A5). That is, the control circuit 8 determines the on-operation time of the user's matrix key 3a to a rhythm such as a quarter note or an eighth note using the tempo of the music set in step A1 as a time base, and performs optimization while performing optimization. Although performance data is generated, the minimum unit of the rhythm required according to the music that the user intends to create may be an eighth note, a sixteenth note, or the like in some cases. Therefore, by setting the minimum resolution to an eighth note, a sixteenth note, or the like in advance, it is possible to prevent the control circuit 8 from determining an unnecessary detailed rhythm.

Next, the user sets a performance part to be input (step A6). That is, D of the tone processing unit 13
The SP is configured to be able to simultaneously reproduce a plurality of (for example, four) performance parts.
4 can be input in parts such as main melody, anti-melody, chord backing, and bass. Therefore, here, any one of the parts 1 to 4 is designated as an input target.

Next, the user selects a tone color of the musical tone (step A7). The tone color of the musical tone is determined by R
The OM stores, for example, a rectangular wave, a triangular wave, or more complicated waveform data close to an actual musical instrument, and selects from among them.

Subsequently, the user sets a performance part to be reproduced simultaneously with the input (step A8). As described above, the DSP of the tone processing unit 13 can simultaneously play back a plurality of performance parts. Therefore, if there is a performance part that has already been input, a new part is played while playing that part. In some cases, inputting may make it easier to grasp the tempo of the music. Therefore, a performance part to be reproduced simultaneously is selected as necessary.

Then, when the user turns on a specific key (any key of the key operation unit 3) assigned to start input, the control circuit 8 starts input processing (music composition processing). When the user turns on a specific key assigned to end input, the input process ends (steps A9 to A12). The inputted notes are displayed on the display unit 6 in the form of a musical score in accordance with the determination result of the control circuit 8 (step A11, see FIG. 9).

Here, the input processing is performed, for example, as shown in FIG. Now, in step A1, BPM = 60
It is assumed that the time signature is set to 4/4 in step A3 and the minimum resolution is set to 16th note in step A5. Note that the setting of BPM = 60 is, for example,
When the tempo at the time of reproduction is BPM = 120 and the music is proper, the tempo is set to be slow to facilitate real-time input processing. Then, the user
While watching the blinking of the ED 14, the input tempo is grasped and the input timing (operation timing of the key 3a) is determined.

In FIG. 7, ○ represents the time when the key 3a is turned on,
● indicates the off point of the key 3a. In this case, quarter note 1
The length of the beat is 1 s, as described above, and the control circuit 8 uses the time base. The on / off operation of the matrix key 3a, the "F" key, and the "clear" key by the user is determined. The minimum resolution of the sixteenth note is 25
0 ms. Therefore, the control circuit 8 determines, for example, the first beat of the measure from the beginning (0 s) of the measure to ± α (25
Since the ON of the key 3a is detected within 0 ms / 2 = 125 ms, it is determined that the sound is generated from the beginning of the measure (without a rest). Since the key is detected to be off within ± α from the beginning (1s) of the second beat, the rhythm of the input note is determined to be a quarter note and stored.

At this time, the control circuit 8 supplies a signal indicating the on / off state of the key 3a to the musical tone processing section 13 so that the musical tone of the tone specified in step A7 corresponds to the on-time (in real time). (On-off).

In the subsequent second beat, the on is not detected within ± α from 1.0 s, and the ON of the key 3a is detected within ± α from 1.5 s. And the key 3a is turned off ± α from the beginning of the third beat (2s).
The rhythm of the input note is determined to be an eighth note and stored. Thereafter, the control circuit 8 similarly makes a determination on the third and fourth beats, and
To determine. "F" for changing the octave
Regarding the ON operation of the key and the "clear" key, the control circuit 8 does not measure the ON time, but simply determines whether or not there is an ON operation while any of the matrix keys 3a is ON. .

When performing an accompaniment (chord backing) using a chord in any of the performance parts, the chord can be designated with only one key as follows. FIG. 8 shows a C major (C major) diatonic scale code (hereinafter referred to as a DC code). A DC code is a code that is used relatively frequently in the corresponding tonality. Therefore, when the input of the accompaniment part is started after the key operation for designating the chord is performed, the corresponding DC code is designated by turning on the lowest tone of the DC chord shown in FIG.

That is, when the "1" key corresponding to "do" is turned on, the one-time code (C) of "domiso" is designated, and the "6" key corresponding to "fa" is designated. If turned on, "Farad" four-degree code (F)
When the "8" key corresponding to "SO" is turned on, the five-degree code (G) of "SOSIRE" is designated. The chords of the fourth and fifth degrees are expanded and sounded as "Dofara" and "Shireso". In the case of the C minor (in C minor), if the lowest note is specified in the same manner, the first, fourth, and fifth chords become Cm, Fm, and Gm, respectively.

When the input processing in steps A9 to A12 is completed as described above, the user subsequently selects whether or not to shift to a correction mode for correcting the input tone data (step A13). If not performed, it is selected whether or not to input another performance part (step A14). If another performance part is to be input, the process proceeds to step A1 and the above-described processing is repeated.

For example, if the performance part shown in FIG. 9 is used as the main melody part A and a bass sound is input to part B as an accompaniment as shown in FIG. 10, part B is selected in step A6 and step A7 is selected. , An appropriate tone color is selected as the base sound, and in step A8, the input part A is set to be reproduced. If the notes to be input are long and the number of inputs is relatively small as in Part B, the tempo in step A1 is set earlier, or the resolution in step A5 is set to quarter notes or half notes. You may fix it.

When the user selects the correction mode in step A13, the input tone data is corrected in real time (step A16). FIG.
It is a flowchart which shows the content of a correction process. The user operates the key operation unit 3 to scroll the musical score displayed on the display unit 6, and specifies a measure to be corrected (step B1). Then, the user moves the cursor 15 (shown by a broken line in FIG. 11A) displayed on the display unit 6 on the screen to specify a note to be corrected (step B2).

Then, the control circuit 8 is displayed on the screen of the display unit 6.
The pitch (mi) and pitch (↑
(One octave higher)) and rhythm (eighth notes) are shown. Then, the user moves the cursor on the screen to the item to be corrected, and corrects it with a scroll key (not shown) or the like (step B3).

For example, if the scroll key in the up direction is operated once in the item "pitch", the pitch changes from "fa" to "fa #" on the semitone, and if the scroll key in the down direction is operated once. The pitch changes from "F" to "Mi", which is a semitone lower. Further, if the scroll key in the up direction is operated once in the item “rhythm”, the rhythm becomes 8 rhythms.
From the minute note, it changes by the minimum resolution 16th note to become a dotted eighth note, and if the scroll key in the down direction is operated once, the rhythm changes from the eighth note to the 16th note.

Here, it is assumed that the pitch is changed from "fa" to "la" and the rhythm is changed from eighth note to quarter note. Then, as shown in FIG. 11B, the note to be corrected is corrected. In step B4, if there is another note to be corrected, step B1
Returning to the step, the same correction is performed, and when the correction is completed, the process returns.

When the input of all the performance parts is completed as described above (step A14: "NO"), the tempo at the time of reproducing the input music is set to BPM = 120 or the like, and the processing is ended. The music data input as described above is transferred to the RAM inside the tone processing unit 13.

Next, a case where the input music data is reproduced will be described. FIG. 5 is a flowchart of a reproduction process performed by the control circuit 8 side. First, the user selects and specifies a performance part to be reproduced in step C1. For example, both parts A and B shown in FIG. 10 may be specified at the same time, or only part A and only part B may be specified.

When a key operation for starting reproduction is performed, the control circuit 8 gives a command to the musical sound processing section 13 to reproduce musical sound data (steps C2 and C3). Thereafter, the music is reproduced until the reproduction of all the musical sound data is completed by the musical sound processing unit 13 or until the user performs a key operation for ending the performance (step C).
4).

In this case, for example, in step C1, only the part B is designated and reproduced, and the user operates the matrix key 3a during the reproduction to play the main melody of the part A in real time. Is also possible.

FIG. 6 is a flowchart of the tone processing section 13 during the reproduction process. Note that this reproduction processing is repeatedly executed at short intervals of, for example, about 10 ms. First, when the tone processing unit 13 reads the waveform data of the timbre specified by the data from the internal ROM (step D1), the tone data is modified (deformed) according to the pitch and rhythm of the tone data (step D1). Step D2).

For example, as shown in FIG. 12A, the waveform data is a rectangular wave, the pitch at the time of storing the waveform data is C, and the pitch to be reproduced at that time is higher than that. In this case, as shown in FIG. 12B, the waveform data is deformed so that the cycle of the waveform data becomes shorter in accordance with the playback pitch. In addition, as shown in FIG. 12C, the waveform is looped according to the tempo of the music and the time corresponding to the rhythm of the note to be reproduced.

In the following step D3, when there is another part to be reproduced at the same time, the process shifts to step D1, and the same processing is performed for the tone color of that part. When the processing is performed for all parts, the reproduced waveforms of the parts are combined (step D4). That is, for example, FIG.
As shown in FIGS. 13A and 13B, when the timbre waveform of the part A is a rectangular wave and the timbre waveform of the part B is a triangular wave, the two waveforms are added and synthesized to obtain a waveform as shown in FIG. Becomes Although the pitches indicated by the waveforms of both parts are the same for convenience of illustration, the present invention is not limited to this.

Then, the tone processing section 13 outputs the data of the synthesized waveform to the audio processing section 9 (step D).
5). Then, the audio processing unit 9 converts the given data into D
/ A conversion and output from the speaker 5 or a speaker (not shown) dedicated to a ring tone.

As described above, according to the present embodiment, when the user creates a musical composition, the control circuit 8 assigns the 12 matrix keys 3a to the 12 chromatic pitches existing within one octave. The pitch order corresponds to the arrangement order of the keys 3a. When the user turns on any one of the matrix keys 3a when creating a music, the pitch corresponding to the key is sounded during the on-operation time, and each key is turned on / off in real time. Thus, data generated based on this is stored, and music composition can be performed in real time.

That is, the twelve chromatic intervals correspond to the twelve matrix keys 3a in a one-to-one correspondence, and the interval (degree) of each interval corresponds to the arrangement interval of the keys 3a. Since the arrangement is close, the user can create music more easily than in the past. The user can play a melody or the like in real time as if playing a musical instrument by turning on / off the key 3a, and was able to present a new way of playing with the mobile phone device 1.

In addition, unlike conventional techniques, music such as a ringtone can be easily created in real time by playing a musical instrument without using a cumbersome procedure such as programming of a computer program.

Further, according to the present embodiment, the control circuit 8
Since the range of the chromatic pitch corresponding to the matrix key 3a can be shifted in advance, for example, from C (C4) to C (B
Even for songs that cannot be played within one octave up to 4), performance and input can be easily performed by turning on each key as much as possible without simultaneously operating auxiliary keys for changing octaves. In this case, the control circuit 8 sets the range to
Since the shift is performed in units of columns of the array of the matrix keys 3a, even when the range is shifted in advance, the positional relationship between the respective pitches does not fundamentally change, and the user can perform the performance by operating the keys without being confused. .

When the user creates a musical composition, the control circuit 8 sets the LE based on the set time signature and tempo.
Since the guide light is emitted by D14, the user can take the time signature and the tempo at the time of input while watching the emission of the guide light, and can more easily perform music composition in real time.

Further, based on the tempo of the music set by the user and each ON operation time of the key 3a by the user, the control circuit 8 changes the rhythm of each input sound such as a quarter note or an eighth note. The user is able to more easily create a song because it is automatically determined to which one is closest to which of the songs. By setting the resolution for the optimization to 8th note, 16th note, or the like in advance according to the music or the like, it is possible to avoid inputting unnecessary detailed rhythms. Can be created more efficiently.

In addition, since the control circuit 8 can independently correct each sound of the performance part created in real time, even if an input fails in music creation in real time, an arbitrary sound is designated. It can be modified, and the degree of completion of the music can be increased. In addition, since a plurality of performance parts can be input independently, multi-part reproduction can be performed by the tone processing unit 13 capable of simultaneously producing a plurality of musical tones based on the created performance data. ) Can be performed.

Furthermore, when the user creates a music piece for a new performance part, the music processing section 13 can reproduce another already created performance part.
The user can create a new performance part in real time while listening to the created performance part,
The time signature and tempo at the time of input become easier to take.

Further, the tone processing section 13 can simultaneously produce a plurality of sounds in one performance part, so that, for example, a chord can be sounded in the part that accompanies the main melody. Then, the tone processing unit 13
Can selectively reproduce a plurality of performance parts for which music has been created, so that a so-called karaoke-like play style can be achieved.

In addition, the control circuit 8 enables the created sound to be displayed in the form of a musical score on the display unit 6 when the user creates a music piece or reproduces the created performance part. Therefore, the user can know how the created sound is represented on the musical score, and can also view the reproduced musical tone as the musical score.

(Second Embodiment) FIGS. 15 and 16 show a second embodiment of the present invention. The same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Only the parts will be described. The configuration of the second embodiment is basically the first configuration.
This is the same as the embodiment, and the software control in the control circuit 8 is different.

That is, when the user selects the music composition mode in the same manner as in the first embodiment, the control circuit 8 of the portable telephone device 1A controls the twelve matrix keys 3a of the key operation unit 3 as shown in FIG. , The numeric key 3a (N) “1”
A major scale (C major) interval is assigned so as to make a transition from "do (C)" to higher "si (B)" from "to (7)". Furthermore, for the numeric keys 3a (N) “8” to “0”, the “do (C4)” to “mi (E4)” assigned to the numeric keys 3a (N) “1” to “3” are assigned. The pitches of “do (C5)” to “mi (E5)” one octave higher are assigned.

Then, the control circuit 8 operates the "*" key 3a
(*) And the "#" key 3a (#) are set as semitone control keys. That is, when the “*” key 3a (*) is turned on together with any one of the numeric keys 3a (N) “1” to “0”, “C” (C) assigned to those numeric keys 3a (N) is turned on.
4) When the pitch between "↑" and "↑ (E5)" is lowered by one semitone and the "#" key 3a (#) is turned on together with any of the numeric keys 3a (N) "1" to "0", Their numeric keys 3
The pitch assigned to a (N) is controlled to be raised by a semitone.

FIG. 16 is a flowchart showing the processing contents of the control circuit 8 when the user operates the matrix key 3a in the music composition mode, and involves steps A9 to A12 shown in the flowchart of FIG. 3 in the first embodiment. This is a detailed representation of the part (however, the part corresponding to step A11 is omitted).

That is, the control circuit 8 waits until a key operation is performed on any one of the key operation units 3 (step E1), and if there is a key operation ("YES"), it becomes "1".
It is determined whether or not it is the numeric key 3a (N) of "0" (step E2). If it is not the numeric key 3a (N) ("NO"), a process corresponding to that key is performed (step E2a), and the process returns to step E1.

Then, the control circuit 8 turns on the numeric keys 3a (N) of "1" to "0" (step E).
2, “YES”), in the next steps E3, E4
At the same time, "#" key 3a (#) or "*" key 3a
It is determined whether or not (*) is turned on. If none of the keys has been turned on (step E4, "N
O ") It is set so that the musical tones of the pitch assigned to the numeric keys 3a (N) of" 1 "to" 0 "are output as they are (step E7). Then, when the numeric keys 3a (N) of "1" to "0" are turned off (step E8,
"YES"), the output of the musical sound is stopped (step E).
9).

The processing of steps E2 to E9 is performed in the same manner as in the first embodiment described with reference to FIG. That is, the control circuit 8
A signal indicating ON / OFF of the key 3a is supplied to the musical tone processing section 13 so that a musical tone of a designated tone color is generated during a period corresponding to the ON time.

Subsequently, the control circuit 8 stores the data of the pitch and rhythm in the storage unit 12 (step E10).
Then, it is determined whether or not the user has performed an operation of ending the creation of the music (step E11). If the creation is to be continued ("NO"), the process returns to step E1 and waits for the next key operation.

On the other hand, in step E3, the numeric key 3
When the "#" key 3a (#) is turned on at the same time as the a (N) ("YES"), the control circuit 8 sets the numeric key 3
When the tone assigned to a (N) is set to be raised by a semitone to output a musical tone (step E5), the process proceeds to step E8. If the “*” key 3a (*) is simultaneously turned on simultaneously with the numeric key 3a (N) (step E4, “YES”), the control circuit 8 sets the numeric key 3
If the tone assigned to a (N) is set to be lowered by a semitone to output a musical tone (step E6), the process proceeds to step E8.

As described above, according to the second embodiment, the control circuit 8 controls the number keys 3a (N) in the key operation section 3.
From "1" to "7", "do (C)" to "shi (B)"
Is assigned to the major scale, and then the numeric key 3a
(N) Numeric keys 3a (N) for "8" to "0"
"C (C4)" assigned to "1" to "3"
“Do (C) one octave higher than“ Mi (E4) ”
5) The pitches from "” "to" ↑ (E5) "are assigned.

Then, the "*" key 3a (*) and "#"
Key 3a (#) is set as a semitone control key,
When the "*" key 3a (*) is turned on together with any of (N), the pitches of "do (C4)" to "mi (E5)" assigned to those numeric keys 3a (N) are changed. Decrease semitone, and press “#” key 3a with any of numeric keys 3a (N)
When (#) is turned on, those numeric keys 3a
The pitch assigned to (N) is controlled to be raised by a semitone, and the music is created by real-time input as in the first embodiment.

Therefore, the user can change the scale interval and the number key 3
a (N) can be easily grasped, and the pitch assigned to the numeric keys 3a (N) can be generated in real time while changing the pitch by a semitone as necessary. And perform in real time. Further, since the two semitone control keys are set for ascending and descending, the user can flexibly change the pitch by a semitone.

(Third Embodiment) FIG. 17 shows a third embodiment of the present invention. In the third embodiment, the correspondence between pitches and semitone control keys for each key in the key operation unit 3 is further modified based on the second embodiment.
That is, as shown in FIG. 17, in the mobile phone device 1B, the correspondence between the numeric keys 3a (N) from "1" to "9" and the scale intervals is the same as in the second embodiment, but "*". "," 0 "and"#"keys are arranged in columns, respectively," M (E5) "," F (F5) ", and" S (G)
5) "is assigned.

The start key 3S and the end key 3E are set as a semitone lowering control key and a semitone raising control key, respectively. According to the third embodiment configured as described above, the range of musical tones that can be output in real time can be expanded by one key operation, so that the user can perform operations for creating music or performing in real time. Can be performed more easily.

The present invention is not limited only to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. A different performance level may be set for each part. The arrangement of the pitches with respect to the arrangement of the matrix keys 3a may be transposed in a matrix. In this case, the pitch may be shifted in units of rows. The metronome means may be configured to also emit a guide sound (click sound) based on the set time signature and tempo. With this configuration, the user can take the time signature and tempo at the time of input while listening to the guide sound.

The following can be considered as an input method of the part for performing the code backing. That is, in the real-time input, only the single pitch corresponding to the chord route is input. Then, in the correction mode, after moving the cursor to the note of each root, input is performed by designating only one or two sounds that characterize each chord.
For example, if the route is de (C), as follows:
It is possible to specify a code. C # C9 Cm C CSUS4 C- C + C6 C7 CM7 And if the route is Mi (E), the corresponding route changes from C to E To respond. If you want to specify more than 4 minor chords,
Cm6 can be designated by designating C # and La #, and Cm7 can be designated by designating C # and La #. Alternatively, similarly, after moving the cursor to the note of each route, other sounds constituting the chord may be input by turning on a plurality of keys. Of course, for example, three or more keys may be simultaneously turned on and input in real time.

The minimum resolution in the optimization processing at the time of real-time input may be fixed. In addition, the appropriateness processing itself and the correction processing may be executed as needed. The metronome means is not always necessary if, for example, there is only one performance part. Further, even in the case of a multi-part, for example, a method of inputting subsequent performance parts based on a performance part input first (or inputting a pattern serving as a guide rhythm to one performance part). Is also possible. A method of displaying musical sound data at the time of input or reproduction in the form of a musical score may be implemented as necessary. The tone generating means is not limited to a DSP.
An M tone generator IC or a PCM tone generator IC may be used. It is also possible to bring together a plurality of portable telephone devices, input a performance part constituting the same music to each device, and perform the ensemble by playing the same at the same time. In this case, for example, a configuration may be adopted in which the performance is synchronized by transmitting a synchronization signal from any one device to another device via the base station. Further, for example, a synchronization signal may be directly transmitted from one to the other using an interface such as IrDA or BLUETOOTH.

In the second embodiment, the numeric keys 3a (N)
Only “do” to “shi” may be assigned to “1” to “7”. Also, the semitone control key is not necessarily for semitone elevation,
It is not necessary to provide two for lowering the semitone, and only one of them may be provided. In addition, the correspondence between each key and the pitch or the semitone control key in the second and third embodiments is not limited to these. For example, the function corresponding to the top two rows of the key operation unit 3 is the bottom two rows. , And the function corresponding to the matrix key 3a may be shifted upward by two columns. Also, in the second and third embodiments, when the semitone control key is turned on while the sound is being generated at a certain pitch, the pitch is smoothly raised or lowered by a semitone from that point in time, so-called bending or choking. Such an effect may be provided.
The PHS (Personal Handyphone Syste
m) shall be included.
