Embodiments of the present invention will be described below with reference to the drawings.
(1) First Embodiment (1-1) Configuration FIG. 1 is an external view of a musical tone control apparatus 1 according to a first embodiment of the present invention.
The main body 10 of the musical sound control device 1 is provided with a display unit 11 such as a liquid crystal display, an operation unit 12 having a plurality of switches, and a plurality of LEDs (Light Emitting Diodes) 13. Various sensors such as a pulse sensor 14 and acceleration sensors 15a and 15b are connected to the main body 10 via a communication cable. The pulse sensor 14 is used to detect a user's pulse, and is attached so as to sandwich the user's earlobe with a clip. The acceleration sensors 15a and 15b are used to detect the physical state of the attached site. For example, the acceleration sensors 15a and 15b are attached so that clothes on the left and right elbows of the user are sandwiched between clips. Further, the main body 10 is connected to an inner earphone 16 (hereinafter referred to as an earphone) via a communication cable, and is provided with a loop-shaped strap 17. A user hangs the strap 17 on his / her neck, inserts the earphones 16 into the left and right ear holes, and uses the musical sound control device 1 with the pulse sensor 14 and the acceleration sensors 15a and 15b attached to predetermined portions.

Next, FIG. 2 is a block diagram showing a hardware configuration of the musical tone control apparatus 1.
The musical sound control device 1 includes a gyro sensor 18 in addition to the pulse sensor 14 and the acceleration sensors 15a and 15b described above. The gyro sensor 18 is used to detect how the orientation of the user's body has changed. The control unit 100 analyzes the output signals from the above-described sensor group (the pulse sensor 14, the acceleration sensors 15a and 15b, and the gyro sensor 18) by executing the computer program stored by itself, and the user (moving body). Is determined, and music data in the MIDI (Musical Instrument Digital Interface) format is generated in accordance with a predetermined algorithm for each physical condition.

  Moreover, the control part 100 controls the lighting period and lighting timing of LED13 so that a user himself can understand visually the physical state of the user detected by the said sensor group. For example, if the user exercises vigorously or the heart rate rises, the LED 13 blinks in a relatively short cycle, and if the user does not exercise much or the heart rate falls, For example, the LED 13 blinks in a long cycle. The musical sound generation unit 19 includes a sound source, an effect applying circuit, and an A / D conversion circuit (both not shown), generates a musical sound signal based on the music data in the MIDI format supplied from the control unit 100, This is supplied to the earphone 16. A tone corresponding to the tone signal is emitted from the earphone 16. In this way, the user can listen to the music reproduced by the musical sound control device 1.

  As described above, the control unit 100 analyzes the output signal from the sensor group to determine the state of the user (moving body) to which the sensor group is attached, and composes music in real time according to the determined state. It can be performed. The composition algorithm will be described below.

  FIG. 3 is a block diagram illustrating a configuration of the control unit 100. The control unit 100 is a microcomputer including a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102, and a nonvolatile storage unit 103. The RAM 102 is provided with a composition table temporary storage area 102a in which the composition table is temporarily stored. This music composition table is used to generate music data according to the physical condition of the user, and describes combinations of music element data constituting the music.

  The nonvolatile storage unit 103 is, for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory) or an SRAM (Static Random Access Memory) in which a backup power source is secured. In addition to the control program 200 executed by the CPU 101, the nonvolatile storage unit 103 stores various types of information used when the program is executed. Further, the non-volatile storage unit 103 is provided with a composition table storage area 103a in which a composition table is stored. The information stored in the nonvolatile storage unit 103 includes a physical condition determination table 201, a composition table 202, a genre-specific template 203, and a music element library 204. Hereinafter, the contents of these pieces of information will be specifically described.

  The body state determination table 201 is a table for the CPU 101 to determine the user's body state based on an output signal from the sensor group. The “user's physical condition” here includes, for example, an internal state of the body such as “shortness of breath” in addition to physical movement itself such as “walking”. In the body state determination table 201, as shown in FIG. 4, detection values obtained by analyzing output signals from the respective sensors and body states are described in association with each other. For example, when the acceleration is up to 0.1 m / s and the heart rate is 50 to 75 times / minute, it is determined that the user's physical condition is “stopped” and the acceleration is 0.1 to 1 m / s. Thus, when the heart rate is 75 to 90 times / minute, the physical condition of the user is determined to be “walking”. When the heart rate is as high as 220 or more, it is determined as “shortness of breath” regardless of the magnitude of acceleration. The correspondence relationship between the detection value by such a sensor group and the physical state may be determined in advance, but for example, since the heart rate varies among individuals, the user can freely set it using the operation unit 12 or the like. It is good also as a simple structure.

  Next, the music element library 204 includes a large number of music element data constituting the music. As shown in FIG. 3, the music element data includes two types of loops (a music element of a certain period that is repeatedly played back), a phrase loop and a pattern loop. The phrase loop represents a melody line of a certain period that is played by a musical instrument (for example, piano or bass) capable of expressing a scale. The pattern loop represents a sound generation timing (rhythm) of a certain period by an instrument that does not express a scale (for example, a percussion instrument such as a drum). The music element library 204 also stores digital data representing sound waveforms that define the timbre of various musical instruments as music element data. The CPU 101 appropriately combines these loops and timbres according to the physical condition of the user, and further generates music data for a certain period by determining the pitch, effect and volume according to the physical condition. Play repeatedly.

  Next, the genre-specific template 203 is a template prepared for each genre of music such as rock, dance, pops, and so on. For example, as shown in FIG. 5, a template of a certain genre describes one or a plurality of loop patterns (a plurality of patterns in FIG. 5) indicating combinations of loops suitable for the genre. Further, one or more patterns (a plurality in FIG. 5) for designating the pitch, tone color, effect (effect), and volume are described in this template. The CPU 101 selects a pattern specified by the music composition table 202 from various patterns described in the genre-specific template 203. In FIG. 5, hatched patterns, that is, “loop pattern A”, “pitch pattern C”, “tone pattern B”, “effect pattern A”, and “volume pattern A” The case where is selected is shown.

  Next, the composition table 202 describes a combination of a loop pattern, a pitch pattern, a tone color pattern, an effect pattern, and a sound volume pattern to be selected in each physical state of the user. FIG. 6 is a diagram illustrating an example of the music composition table 202. In the example of FIG. 6, for example, when the user's physical state is “stopped”, the music is formed by combining the loop pattern A, the pitch pattern C, the timbre pattern B, the effect pattern A, and the volume pattern A. It is stipulated that data should be generated. Similarly, the loop pattern, pitch pattern, timbre pattern, and effect pattern to be selected for each of the physical states "walking", "fast walking", "jogging", "sprinting", "shortness of breath", etc. The combination of volume patterns is defined by the composition table.

  Further, in the present embodiment, even when the current physical condition is “walking”, the contents of the composition table 202 are different depending on the past physical condition. For example, when the physical state transitions from “jogging” to “walking” (ie, when the user's physical state changes from dynamic to static), it seems to be an interlude. There is a composition table with the contents to create a simple song. Also, when transitioning from “stopped” to “walking” (ie, when the state of the moving body has changed from static to dynamic), the atmosphere is more dynamic. There is a composition table with content to generate music. Therefore, also in FIG. 6, a plurality of music composition tables 202a, 202b, 202c,... Are prepared as music composition tables corresponding to the physical state “walking”.

  Furthermore, in addition to the relationship between the current physical state and the previous previous physical state, a composition table is also prepared in consideration of the second previous physical state. For example, transition of the physical state of “stopped” → “jogging” → “walking”, “walking” → “jogging” → “walking”, “stopped” → “running” There are quite a few combinations, such as “Yes” → “Walking”. Similarly, a plurality of composition tables are prepared for composition tables corresponding to other physical conditions.

  Thus, the composition table 202 describes different combinations of patterns according to time-series physical states from the past to the present of the user (exercise body), and the CPU 101 stores the user (exercise body). The music data is generated by combining the patterns corresponding to the time series states of By composing with such a mechanism, it is possible to create a music that more accurately reflects the physical condition of the user, and to make the user feel more interesting.

(1-2) Operation Next, the operation of the first embodiment will be described.
FIG. 7 is a flowchart showing the processing procedure of the CPU 101 described in the control program 200. When the user performs a predetermined operation using the operation unit 12 and gives an instruction to start playing the music, the CPU 101 executes the control program 200 stored in the non-volatile storage unit 103 to execute the operation. A series of processes shown in FIG.

  First, the CPU 101 causes the display unit 11 to display a menu screen for allowing the user to select a genre of music (step S1). The music genres are hierarchically structured. For example, as shown in FIG. 8, the upper layers are divided into broad genres such as rock, dance, pop, reggae, Latin, and so on. For example, if the genre is rock, the genre is subdivided into lower layers such as hard rock, British rock, and American rock. Of course, the genre is not limited to such two hierarchies, and may be composed of more hierarchies.

  The user operates the operation unit 12 to select a desired genre of music. Here, for example, if “American rock” is selected as shown in FIG. 8, the CPU 101 accepts this selection operation (step S2; Yes), and generates a genre-specific template 203 corresponding to the selected genre (American rock). Reading from the non-volatile storage unit 103 (step S3). As a result, as shown in FIG. 8, a genre template 203 corresponding to American rock is extracted from a large number of genre templates.

  Next, the CPU 101 takes in output signals from the sensor group (pulse sensor 14, acceleration sensors 15a and 15b, and gyro sensor 18) (step S4). Then, the CPU 101 analyzes the captured output signal to obtain a detection value, and refers to the detection value and the body state determination table 201 to determine the user's body state (step S5). Here, for example, the detection values (acceleration) by the acceleration sensors 15a and 15b are both acceleration 0.05 (m / s), and the detection value (heart rate) by the pulse sensor 14 is 60 (times / minute). Assume. In this case, the CPU 101 determines that the physical condition is “stopped” in accordance with the contents of the physical condition determination table 201 shown in FIG. 4.

  Next, the CPU 101 determines whether or not the physical condition has changed (step S6). The “change in the physical state” here is a case where there is a time-series change in the physical state of the user, for example, a change from “walking” to “stop”. In the first determination after the processing shown in FIG. 7 is started, the CPU 101 always determines that the physical state has changed (step S6; Yes), and proceeds to the next processing.

  Next, the CPU 101 reads out the music composition table 202 corresponding to the physical condition determined in step S5 from the nonvolatile storage unit 103, and stores it in the music composition table temporary storage area 102a of the RAM 102 together with the genre name (here, “American rock”). (Step S7). At this time, the CPU 101 also stores information indicating the physical state (here “stopped”) determined in step S5 and information indicating the date and time at that time in association with the music composition table 202 as attached information. These composition table 202 and genre names are not exactly the same as the music data in step S8, but function as parameters for generating these composition tables 202 and genre names, so the CPU 101 composes these as music data. Save in the temporary table storage area 102a.

  Then, the CPU 101 generates MIDI format music data based on the stored music composition table 202 and the genre-specific template 203 read in step S3 (step S8). In this example, the composition table 202 corresponding to the physical state “stopped” and the genre-specific template 203 corresponding to American rock are used.

FIG. 9 is a diagram for specifically explaining an example of a state in which music data is generated.
The CPU 101, among the various patterns included in the American rock genre template 203, the loop pattern A, the pitch pattern C, and the timbre specified by the composition table (see FIG. 6) corresponding to the physical state “stopped”. A pattern B, an effect pattern A, and a volume pattern A are selected.

  The loop pattern A designates “pattern loop c” as part 1 among the various loops included in the music element library 204. The pitch pattern C does not specify a pitch. The timbre pattern B designates the timbre of Part 1 (here, pattern loop c) as “drum”. The effect pattern A specifies that part 1 (here, pattern loop c) is to be given echo (reverberation). The volume pattern C specifies that the volume of part 1 (pattern loop c) should be increased. When the CPU 101 generates a piece of music data with the contents specified by these patterns, the CPU 101 starts the reproduction process (step S9 in FIG. 7).

  Then, after starting the reproduction of the music, the CPU 101 returns to the process of step S4, takes in the output signal from the sensor group again, and determines the physical state of the user. While the CPU 101 determines that the physical condition has not changed (step S6; No), while playing the music as it is, step S4 → step S5 → step S6; No → step S4 → step S5 →. Repeat the process. That is, the CPU 101 repeatedly reproduces the same music data as long as there is no change in the user's physical condition. This allows the user to listen to music that is continuously played.

  On the other hand, when the user's physical state changes (step S6; Yes), the CPU 101 generates new music data using the music composition table 202 corresponding to the physical state (step S7). Then, the CPU 101 reproduces the generated music data instead of the music data that has been reproduced so far. Thus, the user can know that his / her physical condition has changed by changing the contents of the reproduced music.

  By the way, when the user likes the music while listening to the music being reproduced, the user performs an operation of instructing “save” using the operation unit 12. The CPU 101 executes the process shown in FIG. 10 in response to this operation. That is, when the CPU 101 detects that an operation for instructing “save” has been performed on the operation unit 12 (step S11), the composition table 202 stored in the composition table temporary storage area 102a, the genre name and its associated information. Is written into the composition table storage area 103a of the nonvolatile storage unit 103 (step S12). At this time as well, as described in the description of step S7 in FIG. 7, the CPU 101 stores the music composition table 202 and the genre name as music data in the music composition table storage area 103a.

  When the user wants to play the stored music at a desired time, the operation unit 12 is used to instruct “play”. The CPU 101 executes the process shown in FIG. 11 in response to this operation. That is, when the CPU 101 detects that an operation for instructing “play” is performed on the operation unit 12 (step S21), the composition table 202 stored in the composition table storage area 103a of the nonvolatile storage unit 103, the genre Read name and associated information. Then, the CPU 101 uses the read composition table 202 and the genre-specific template 203 corresponding to the read genre name to generate music data in the same procedure as step S8 in FIG. Playback is performed (step S22). At the same time as the reproduction, the CPU 101 displays (outputs) the physical state and date / time at the time of the composition included in the already read attached information on the display unit 11. In this way, the user can save his favorite music and play it freely when he likes it.

  Next, FIG. 12 is a diagram illustrating a time-series change in the physical state and a state in which the contents of the music composition table 202 transition according to the change. As shown in FIG. 12, in the first "stopped" state, a composition table specifying loop pattern A, pitch pattern C, timbre pattern B, effect pattern A, and volume pattern A is composed. Used. In this case, it is a stage before the user begins to move the body, so there is a song with a quiet and calm atmosphere, and a music with a reverberation effect reverberating as described above. Will be made. When reverberation is applied, the effect applying circuit of the tone generator 19 convolves the sample data of the impulse response waveform with the coefficient instructed by the CPU 101 with the tone data of each part. As a result, a reverberation effect having a magnitude specified by the composition table 202 is given to the musical sound represented by the musical tone data output from the effect applying circuit.

  Thereafter, a case is assumed in which the body state changes from “stopped” to “walking”. In the case of the physical condition of “walking”, considering the combination with the previous physical condition of the previous one, (stop →) walking, (fast walking →) walking, (jogging →) walking There are a number of physical states, such as walking (full sprinting →) walking, (shortness of breath →) walking, and so on. Therefore, the composition table prepared for the transition of the physical state of (stopped →) among the composition tables prepared for the plurality of transitions of the body state is selected by the CPU 101. In the example shown in FIG. 12, a music composition table in which a loop pattern C, a pitch pattern C, a timbre pattern A, an effect pattern C, and a volume pattern B are specified is used. In this case, since the user has started to move the body, the music that has a sense of movement that makes you feel that something will happen in the future, for example, the piano prelude melody and the drum accompaniment part are slightly faster. A song that progresses at a tempo is created.

  Specifically, the loop pattern C designates “phrase loop a” as part 1 among various loops included in the music element library 204, designates “phrase loop b” as part 2, and designates “phrase loop b” as part 3. Designate pattern loop d ". In addition, the pitch pattern C specifies that Part 1 (here, phrase loop a) is “semitone higher”. Tone pattern A designates the tone of Part 1 (here, phrase loop a) as “piano”, designates the tone of part 2 (here, phrase loop b) as “bass”, and part 3 (here, pattern loop) The tone of d) is designated as a drum. The effect pattern C specifies that an echo (reverberation) is given to part 3 (here, phrase loop a). The volume pattern B specifies to increase the volume of part 2 (phrase loop b). When the CPU 101 generates music data for a certain period with the contents specified by these patterns, it starts the reproduction process.

  After that, when the body state transitions to “stopped” again, it is prepared for the transition of the body state from the previous and the previous one of (stopped → walking →) stopped. The music composition table is selected by the CPU 101. In the example shown in FIG. 12, a music composition table in which a loop pattern B, a pitch pattern E, a timbre pattern D, an effect pattern C, and a volume pattern B are specified is used. In this case, music such as an interlude that feels a pause, for example, music data in which only a bass solo progresses is created.

Here, FIG. 13 is a diagram showing the state in which the content of the music to be played changes in accordance with various changes in the body state so that the user can visually understand.
In FIG. 13, when the user is stopped, a relatively slow tempo pattern loop is played by the drum. Next, when the user starts walking, the drum pattern loop changes, and the drum pattern loop and the bass phrase loop are superimposed on the drum pattern loop. When the user starts jogging further, a fast-tempo pattern loop is played by the drum, and a fast tempo beat by electronic sound is engraved. When the user turns to the right, the drum pattern loop changes and a guitar phrase loop is added. When the user finishes turning to the right, he returns to the jogging song. Also, if the user raises his right hand, the horn will sound only at that time. Then, if the user stops jogging, for example due to waiting for a signal, and stops, only the bass solo will proceed. When the user starts jogging again, a pattern loop different from the previous piano pattern loop is played. However, the drum pattern loop is the same as the previous pattern loop.

  As described above, according to the first embodiment, the user saves the music data (composition table 202 and genre name) designated as “favorite” in the musical sound control device 1 and uses the musical sound when he / she likes it. It can be freely reproduced by the control device 1. Moreover, in this musical tone control apparatus 1, since the state of the user (motor body) is detected by the sensor group, and different music data is generated and reproduced according to the state, the user can , You can listen to music in an atmosphere that harmonizes with your physical condition and you can experience the unique fun. And even if it is in the same physical state, the contents of the music can change depending on how the previous physical state was before that, so the user is not bored.

(2) Second Embodiment In the first embodiment described above, the musical sound control device 1 stores the music composition table 202 and the genre name as music data in the music composition table temporary storage area 102a and the music composition table storage area 103a. In the second embodiment, MIDI-format music data generated based on the music composition table 202 and the genre-specific template 203 is stored in the music composition table temporary storage area 102a and the music composition table storage area 103a. FIG. 14 is a block diagram showing the configuration of the control unit 100a of the musical tone control apparatus according to the second embodiment. The configuration of the control unit 100a shown in FIG. 14 is different from the control unit 100 shown in FIG. 3 in that a buffer memory 104 that reads and writes data in a FIFO (First in First Out) format is provided. Instead of the music composition table storage area 103a of the unit 103, a music data storage area 105 for storing music data in the MIDI format is provided. The buffer memory 104 has the same function as the music composition table temporary storage area 102a on the RAM 102 of the first embodiment. The music data storage area 105 has the same function as the music composition table storage area 103a of the non-volatile storage unit 103 of the first embodiment.

  The operation during composition is as follows. After determining the physical state in step 6 of FIG. 7, the CPU 101 generates music data in the MIDI format on the RAM 102 with reference to the music composition table 202 corresponding to the physical state, and stores it in the buffer memory 104 together with the attached information. Transfer and save sequentially. Then, the CPU 101 sequentially reads out music data from the buffer memory 104 and starts reproduction.

  The operation at the time of storage is as follows. The user performs an operation of instructing “save” using the operation unit 12. In response to this operation, the CPU 101 reads out the music data stored in the buffer memory 104 and its associated information, and writes it in the music data storage area 105 of the nonvolatile storage unit 103. On the other hand, the operation during playback is as follows. When the user performs an operation of instructing “play” using the operation unit 12, the CPU 101 reads out music data stored in the music data storage area 105 of the nonvolatile storage unit 103 in accordance with this operation, Play this as music.

  Also in the second embodiment, music data designated by the user is stored in the musical sound control device 1 and freely reproduced by the musical sound control device 1 when desired, as in the first embodiment. Can do.

(3) Third Embodiment In the first and second embodiments described above, the musical sound control device 1 generates music data according to the physical condition of the user. In the third embodiment, a plurality of musical sounds are used. The control devices exchange information with each other, and the music data is processed by changing the music element data, the pitch, the timbre, the effect, and the volume according to the information. For example, if the jogging user and the stopped user pass each other, information that characterizes the music played by the musical sound control device used by the former (jogging) is displayed as the latter (stopped). So that the music according to the "stopped" state until then becomes a music with a slightly higher tempo like the music according to the "jogging" state. Processed.
Details of the third embodiment will be described below.

FIG. 15 is a block diagram showing the configuration of the musical tone control apparatus 1a according to the third embodiment.
The configuration of the musical tone control device 1a shown in FIG. 15 is different from the musical tone control device 1a of the second embodiment in that the wireless communication unit 120 is provided and the operation of the control unit 100. The wireless communication unit 120 performs data communication with the wireless communication unit of another musical tone control apparatus using a communication method such as IrDA (Infrared Data Association), Bluetooth (registered trademark), or DSRC (Dedicated Short Range Communication).

FIG. 16 is a flowchart illustrating a procedure described in a control program stored in the control unit 100.
The wireless communication unit 120 intermittently transmits a polling signal to the surroundings according to the procedure determined by the communication method. In parallel with this, the wireless communication unit 120 intermittently receives a polling signal transmitted from the wireless communication unit of another musical tone control device, and the received electric field strength of the polling signal is the electric field strength. It is measured by the measurement circuit 121 (see FIG. 15).

  When the CPU 101 monitors the received electric field strength measured by the electric field strength measuring circuit 121 and determines that the received electric field strength has reached a level that allows data communication with other musical tone control devices (step S41; Yes), While transmitting the characteristic information characterizing the music data generated and reproduced by itself to the wireless communication unit of another musical sound control device, the characteristic information transmitted from the wireless communication unit of the other musical sound control device is received ( Step S42). Here, the “characteristic information characterizing music data” may be, for example, the content itself of the composition table 202 used for composition, or at least one content of loop, pitch, tone, effect, and volume. It may be information indicating.

  Based on the content of the received feature information, the CPU 101 changes the loop, timbre, pitch, effect, and volume of the music data that is generated and reproduced by the CPU 101 (step S43). Various processing methods can be considered. For example, the volume of the music being played may be brought close to the volume represented by the feature information, or the playback volume itself may be completely replaced with the volume represented by the feature information. Good. Also, the timbre of the music being played may be changed to a part of the timbre represented by the feature information, or all the timbres being played may be completely replaced with the content represented by the feature information. In addition, the effect represented by the feature information may be given to the music being played, and conversely, when the information related to the effect is not included in the feature information, You may make it remove the effect of the music currently reproduced | regenerated. The CPU 101 stores the music data thus generated in the buffer memory 104 together with the feature information. Then, the CPU 101 sequentially reads the music data from the buffer memory 104 and reproduces the music (step S44). Further, the CPU 101 may display (output) the feature information on the display unit 11 simultaneously with the reproduction. For example, the display unit 11 may display a message such as “There is an influence of a drum” as timbre characteristic information or “semitone high” as pitch characteristic information.

  As described above, in the third embodiment, a plurality of musical tone control devices exchange information with each other, and process and reproduce music data according to the information. In addition to the effects described in the first embodiment, use It is possible to provide music with more variety to the user.

(4) Modification Examples The first to third embodiments described above may be modified as follows.
In the first to third embodiments, the nonvolatile storage unit 103 may be a storage device that can be attached to and detached from the musical sound control device, such as a memory card, an optical disk, or a magnetic disk. In this way, the music stored as a favorite can be reproduced by another musical sound control device.

  In the first to third embodiments, in addition to the current physical condition, the contents of the music composition table 202 are determined in consideration of the two previous and previous previous physical conditions. However, the present invention is not limited to this, and the content of the music composition table 202 may be determined only for the current physical condition, or may be determined in consideration of three or more previous physical conditions. .

  In the first to third embodiments, the music data conforming to the MIDI standard is used, but the format of the music data is not limited to this. For example, music data may be generated using music element data obtained by sampling a signal waveform of a musical sound. Note that the music element library 204 does not need to be stored in advance in the non-volatile storage unit 103 of the musical sound control device 1, and is received by the musical sound control device 1 from a predetermined server device via a network such as the Internet, for example. It may also be data read into the musical tone control apparatus 1 from various recording media represented by optical disks. Note that the timbre of the music is not limited to a musical instrument such as a piano or a drum, and for example, natural sounds such as river sounds and animal sounds may be used.

  In the first to third embodiments, the music data is generated according to the physical state of the user's “human” moving body, but the moving body may be other than a human. For example, the moving body may be an animal other than a human being, may be moved by some external force, such as a weathercock, a bicycle, or a vacuum cleaner, or may have its own power source such as a washing machine or a car. It may be used to move.

  In the first to third embodiments, the configuration in which music data is generated according to the user's physical condition is exemplified, but in addition to this, the instruction input by the user using the operation unit 12 is music data. You may make it reflect in the content of. For example, a timbre part designated by the user may be added to the music, deleted from the music, or adjusted to a playback tempo as intended by the user.

  In the third embodiment, the distance to another musical sound control device may be measured, and the music being played back may be processed based on this distance. Specifically, it is as follows. The CPU 101 can roughly specify the distance from other musical sound control devices by referring to the intensity level measured by the electric field intensity measurement circuit 121 of the wireless unit 120. Therefore, for example, the CPU 101 increases the volume of the music being played as the distance from the other musical sound control device decreases, while playing as the distance from the other musical sound control device increases. Reduce the volume of the song. In this way, the user can experience the approaching or moving away of the user of the other musical sound control device 1 with the volume of the music. In addition, by applying this, it is also possible to give an acoustic effect such as a so-called Doppler effect to music. Further, in this case, distance information representing the measured distance is associated with the song data, temporarily stored in the RAM or buffer memory, or stored in the nonvolatile storage unit, and based on the song data read from the nonvolatile storage unit. When reproducing the music, the distance information stored in association with the music data may be displayed (output). For example, a message such as “closeness of 10 m” or “closer enough to touch” is displayed on the display unit 11.

  The control program may be provided from the predetermined server device to the music sound control device 1 via a network such as the Internet, or may be provided in a state stored in some recording medium and installed in the music sound control device 1. It may be done. As this type of recording medium, in addition to various optical disks represented by CD-ROM (Compact Disk-Read Only Memory), portable magnetic disks and the like are conceivable.
