FIG. 5 is a flowchart illustrating an example of a control pattern corresponding to the load data according to the embodiment, and FIG. 5 is a flowchart illustrating a reproduction preparation process according to the embodiment. Further, FIG. 6 is a flowchart showing control of the number of beats per unit time when the exercise rhythm is increased according to the embodiment, and FIG. 7 shows the control of the number of beats per unit time when the exercise rhythm is increased. It is a figure illustrated. At this time, in FIG. 3, the same member numbers as the respective constituent members in the output control device S are used for the respective constituent members in the examples corresponding to the respective constituent members in the output control device S according to the embodiment shown in FIG. 1. ing.

As shown in FIG. 2, the music player P according to the example corresponds to an example of the output control device S according to the embodiment, and includes a control unit including a CPU, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. S, an operation unit 4 composed of operation buttons or a touch panel, a display 5 composed of a liquid crystal panel, a recording unit 6 composed of HDD (Hard Disc Drive) or SSD (Solid State Drive), etc. And a reproduction output unit 10 as an example of “means”. In this configuration, the control unit S corresponds to an example of the “selecting unit” according to the present application.

The control unit S includes an interface 1 corresponding to an example of the load information acquisition unit 1 according to the embodiment, an example of the “feature information acquisition unit” according to the present application, and an example of the “content information acquisition unit” according to the present application, The change unit 2 is an example of the change unit 2 according to the embodiment, and the output control unit 3 is an example of the output control unit 3 according to the embodiment. Further, the reproduction output unit 10 includes a reproduction unit 10A, a reproduction unit 10B, a mixing unit 10C, and an output unit 10D. At this time, the interface 1, the change unit 2, and the output control unit 3 may be realized by a hardware logic circuit including the CPU and the like constituting the control unit S, and playback according to an embodiment described later. The CPU may read out and execute a program corresponding to a flowchart showing preparation processing or the like, and may be realized as software. Similarly, the reproduction unit 10A, the reproduction unit 10B, the mixing unit 10C, and the output unit 10D may be realized by a hardware logic circuit that constitutes the control unit S, or according to an embodiment described later. It may be realized by software by reading and executing a program corresponding to a flowchart showing control of the number of beats per unit time. In the following description, the “beats per unit time” is simply referred to as “BPM”.

On the other hand, in the recording unit 6, music data MD corresponding to the music reproduced in the music player P according to the embodiment is recorded in a nonvolatile manner for a plurality of music. At this time, each piece of music data MD is composed of main body data B, which is the main body of the music corresponding to the music data MD, and attribute data AT indicating the attributes of the music. The attribute data AT in this case includes data indicating the original BPM of the music corresponding to the attribute data AT and data indicating the author of the music. In the following description, the original (original) BPM of the song is referred to as “original BPM”.

In addition to these, the recording unit 6 records a reproduction list PL, which is a list of songs selected in a reproduction preparation process according to an embodiment described later. The reproduction list PL describes the reproduction order of the music during the exercise according to the embodiment in association with the music identification data for identifying the selected music.

In this configuration, the playback unit 10A and the playback unit 10B of the playback output unit 10 read one of the music data MD recorded in the recording unit 6 under the control of the control unit S, and perform necessary decoding processing, for example. . At this time, for example, the reproducing unit 10B reads the music data MD to be reproduced next while the decoding process or the like by the reproducing unit 10A is being executed, and starts the decoding process or the like. Prepare for playback. Then, under the control of the control unit S, the mixing unit 10C of the reproduction output unit 10 mixes the music data MD after decoding and the like output from each of the reproduction unit 10A and the reproduction unit 10B, and outputs them to the output unit 10D. . Thereby, a so-called cross-fade process using the two music data MD is performed. In the following description, the process for connecting the music M corresponding to the two music data MD (cross fade process, mixing process, etc.) is generally referred to as “cross fade process etc.”. The output unit 10D performs, for example, amplification processing on the music data MD output from the mixing unit 10C and outputs the music data MD to a speaker or an earphone (not shown).

Further, in the above configuration, when an operation for controlling the operation of the music player P according to the embodiment is performed in the operation unit 4, the operation unit 4 generates an operation signal corresponding to the operation and sends it to the control unit S. Output. Thereby, the interface 1 of the control unit S is a load corresponding to the exercise plan set in advance for the exercise performed by the practitioner and should be applied to the practitioner, and the exercise after the start of the exercise corresponding to the exercise plan. Load data indicating a relationship with time is acquired from the outside. The load at this time changes, for example, by changing the exercise rhythm when performing the exercise. Thereby, the change part 2 of the control part S respond | corresponds to the said exercise time shown by the load data acquired by the interface 1, for example, BPM of the music output with respect to the said implementer according to the said exercise time. The reproduction output unit 10 is controlled to change to the content corresponding to the load. And the output control part 3 of the control part S controls the reproduction | regeneration output part 10 so that the said music in which the content was changed may be output according to the said exercise time. Note that information indicating the operation of the music player P according to the embodiment is presented to the practitioner using, for example, the display 5 under the control of the control unit S, for example.

Next, the load data according to the embodiment will be specifically described with reference to FIG. As illustrated in FIG. 3A, the load data LD according to the embodiment includes the load of the exercise to be applied to the performer who performs the exercise while listening to the music output from the music player P according to the embodiment. This is data indicating the relationship between the intensity (in other words, the intensity of the exercise itself or the exercise rhythm of the exercise) and the exercise time after starting the exercise. Such load data LD is input to the control unit S of the music player P for each exercise, for example, in accordance with an exercise plan previously prepared by the person performing the exercise. Here, as an example of the one-time exercise, for example, there is a case where the weight is changed over time in one jogging, one machine running, or one way training. In the case of this weight training, in addition to raising and lowering the weight along the song to be listened to, the weight of the exercise is changed to a heavy object or light by controlling the BPM of the song. You will be conscious of exchanging things.

In the music player P according to the embodiment, as illustrated in FIG. 3B corresponding to the load data LD illustrated in FIG. 3A, the music data MD that is listened to during the above-described one exercise. The BPM of the song M corresponding to is controlled by the control unit S and the reproduction output unit 10 so as to have a time change corresponding to the time change in the load data LD.

Next, the BPM control pattern of the music piece M according to the embodiment controlled in accordance with the load data LD described above will be specifically described with reference to FIG.

First, as a basic form of the control pattern, as illustrated in FIG. 4A, the music M1 (original BPM is 120), the music M2 (original BPM is 180), and the music M3 (original BPM) are different from each other. 80) is shown in the playlist PL. In the following description, when the music M1, the music M2, and the music M3 are collectively referred to, they are simply referred to as “music M”. It is assumed that the BPM of each song M corresponding to the load data LD in the exercise performed while listening to these songs M is 160. In this case, in the music player P according to the embodiment, as illustrated in the right part of FIG. 4A, the BPMs of the music pieces M1 to M3 are all controlled to 160, and the joints between them overlap. As described above, the music pieces M1 to M3 are continuously reproduced and output while performing the above-described crossfade processing and the like. In addition, when the original BPM of the music M3 is doubled to 160, the BPM can be set to 160 without any trouble by using an exercise rhythm that realizes one beat of the music M3 twice. The beat matching control itself and the playback sound volume control itself as the cross-fade processing or the like can adopt the same method as the conventional one.

In addition to these, in the music player P according to the embodiment, the BPM of one music piece M is also controlled from the middle corresponding to the load data LD. More specifically, as illustrated in FIG. 4B, when songs M1 to M3 are shown in the playlist PL, the BPM of the song M corresponding to the load data LD at that time is 160 to 170. In other words, the music player P according to the embodiment performs control to increase the BPM to 170 even if any of the music M1 to the music M3 is reproduced with the BPM set to 160, respectively. At this time, when the BPM is increased to 170 in order to increase the load on the practitioner, the original BPM is set to 170 than the BPM of the music M2 having the original BPM of 180 (see pattern 2-1 in FIG. 4B). If the BPM of 120 pieces of music M1 is set to 170 (see pattern 1-1 in FIG. 4B), it is considered that the implementer is more likely to be conscious of “increasing the exercise load”. This is more conspicuous when the practitioner already knows the songs M1 and M2 themselves. Therefore, when the load on the practitioner is increased corresponding to the load data LD, the music piece M1 of the pattern 1-1 is selected instead of the pattern 2-1, and control is performed so that the BPM is increased from 160 to 170. . As illustrated in the right end of FIG. 4B, the original BPM of the song M3 can be further increased to 170 (see pattern 3-1 in FIG. 4B). However, in the case of this pattern 3-1, since the original BPM is 80 as compared with the desired song whose original BPM is close to 170 (ie, the song M1 or the song M2), the BPM becomes 170 (even if the BPM is 170). Even so) the tone of the song becomes calm, and it is difficult for the implementer to recognize the feeling of “getting faster”. Therefore, the control of the pattern 3-1 is not adopted when the load on the practitioner is increased corresponding to the load data LD.

On the other hand, although not shown, when the BPM is lowered for the purpose of reducing the load on the practitioner, the pattern 2-1 or the pattern 3-1 is more “exercise” than the pattern 1-1. It is thought that it is easy to be aware that "Let's reduce the load of This is also more conspicuous when the practitioner already knows the songs M1 to M3 themselves. Therefore, when the load on the practitioner is reduced corresponding to the load data LD, the music M2 of the pattern 2-1 or the music M3 of the pattern 3-1 is selected instead of the pattern 1-1, and the BPM is reduced. Control is performed.

In addition, as control of which tune M is selected, for example, control is performed so that the BPM is raised after changing to the tune M having a lively tone with many sounds. In this way, before the BPM is raised and the load on the practitioner is increased, the practitioner can first be conscious of an atmosphere in which the intensity of exercise is consciously increased.

On the other hand, in the music player P according to the embodiment, the BPM itself at the time of the music being reproduced at that time is not changed, and the two music M having different original BPMs are made to correspond to the load data LD. Also do. More specifically, as illustrated in FIG. 4C, when songs M1 to M3 are shown in the playlist PL, the song Mn (reproduced corresponding to the load data LD at that time) n is a natural number greater than or equal to 4. The same applies hereinafter.) BPM is 160, and the reproduction of a new song M is started while maintaining this. In this case, in the music player P according to the embodiment, any BPM of the music M1 to the music M3 can be controlled so as to be continuous with the music Mn by setting them to 160.

Here, when jogging, even if the pitch is the same (for example, corresponding to 160 BPM), the speed increases when the stride is extended. Therefore, the exercise plan (load data LD) is speed from the viewpoint of preventing injury. Suppose it's like dropping In this case, when switching from the song Mn to any of the songs M1 to M3 while maintaining the BPM at 160, the BPM of the song M1 whose original BPM is 120 is set to 160 (see pattern 1-2 in FIG. 4C). Rather, the BPM of the song M2 with the original BPM of 180 is assumed to be 160 (see pattern 2-2 in FIG. 4 (c)), and the implementer is more likely to be conscious of “reducing the exercise load”. It is done. As in the case of FIG. 4B, this is more noticeable when the person who knows the music M1 and the music M2 itself in advance. Therefore, when the speed is decreased as described above, the music M2 of the pattern 2-1 is selected instead of the pattern 1-1, and control is performed to connect / reproduce the music Mn immediately before the BPM as 160. As illustrated in the right end of FIG. 4C, the original BPM of the song M3 can be raised to 160 and connected (see pattern 3-2 in FIG. 4C). In the case of this pattern 3-2, the original BPM is 80 as compared to the desired 160 (that is, the music M1 or the music M2), so that the original BPM is 160 (even if the BPM is 160). Even though) the tone of the song is calm, and the implementer can easily recognize the feeling of “slowing down”. Therefore, the control of this pattern 3-2 is also employed when the speed is reduced.

On the other hand, although not shown, when the BPM is maintained at 160 while increasing the speed, the pattern 1-2 is more effective than the pattern 2-2 or the pattern 3-2. It is thought that it is easy to be conscious of "Let's increase exercise load". This is also more conspicuous when the practitioner already knows the songs M1 to M3 themselves. Therefore, when the speed is increased, the music M1 of the pattern 1-2 is selected as the next music instead of the pattern 2-2 or the pattern 3-2, and the BPM is controlled to 160.

Next, playback preparation processing and BPM control in the music player P according to the embodiment will be specifically described with reference to FIGS.

First, reproduction preparation processing according to the embodiment will be specifically described with reference to FIG. In the reproduction preparation process according to the embodiment, for example, when song data MD corresponding to a plurality of songs M having different BPM is recorded in the recording unit 6 as shown in FIG. 2, exercise is performed while listening to them. This is started when the practitioner performs an instruction operation on the operation unit 4.

That is, when the reproduction preparation process according to the embodiment is started, the control unit S acquires the load data LD illustrated in FIG. 3A as an exercise program for exercise executed at that time via the interface 1 ( Step S1). In this step S1, based on the acquired load data LD, data indicating the required number of songs M used for the subsequent exercise is also acquired. Next, based on the load data LD acquired at step S1, the control unit S calculates a target BPM for each piece of music M to be heard during exercise performed based on the exercise plan indicated by the load data LD ( Step S2). Here, the target BPM is, for example, “160” illustrated in FIGS. 4A and 4C and “170” illustrated in FIG. 4B, and corresponds to the load data LD. This is the target value related to the control of the BPM to be controlled. In the following description and FIGS. 5 and 6, the target BPM is appropriately indicated as “Tbpm”.

Next, the control unit S records in the recording unit 6 the music data MD of the music M to which the original BPM belongs within a range of 20% less BPM to 10% more BPM centering on the target BPM. It is confirmed whether or not (step S3).

In the confirmation of step 3, when the music data MD of the original BPM music M that meets the conditions related to step S3 is recorded in the recording unit 6 (step S3; YES), the control unit S selects the corresponding music M. The music identification data to be identified is added to the reproduction list PL (step S4), and then the control unit S determines whether or not the necessary number of music M is described in the reproduction list PL (step S5). When the required number of songs M are described in the playlist PL in the determination in step S5 (step S5; YES), the control unit S is described based on the contents of the playlist PL at that time. For example, the reproduction order of the tune M is determined by the method illustrated in FIG. 4 or by a preset method, and the determined reproduction order is described in the reproduction list PL (step S6). Thereafter, the control unit S stands by until control of BPM, which will be described later, is started for the song M described in the playlist PL.

On the other hand, in the confirmation in step S3, when the music data MD of the original BPM music M that meets the conditions related to the step S3 is not recorded in the recording unit 6 (step S3; NO), or necessary in the determination in the step S5. If a number of songs M are not described in the playlist PL (step S5; NO), the control unit S extracts a more appropriate song M, so that it is centered on half the target BPM (Tbpm / 2). It is confirmed whether or not the song data MD of the song M to which the original BPM belongs is within the range of 20% less BPM to 10% more BPM (step S7, FIG. 4 pattern 3-1). Or refer to Pattern 3-2).

In the confirmation in step 7, when the music data MD of the original BPM music M that meets the conditions in step S7 is recorded in the recording unit 6 (step S7; YES), the control unit S selects the corresponding music M. The music identification data to be identified is added to the reproduction list PL (step S8), and then the control unit S determines whether or not the necessary number of music M has been described in the reproduction list PL (step S9). When the required number of songs M are described in the reproduction list PL in the determination in step S9 (step S9; YES), the control unit S moves to step S6.

On the other hand, in the confirmation in step S7, if the music data MD of the original BPM song M that meets the conditions related to step S7 is not recorded in the recording unit 6 (step S7; NO), or necessary in the determination in step S9. When a number of songs M are not described in the playlist PL (step S9; NO), the control unit S relaxes the condition related to step S3 and extracts the target BPM in order to extract a more appropriate song M. It is confirmed whether or not the music data MD of the music M to which the original BPM belongs is recorded in the recording unit 6 within the range of BPM 30% less than that and 20% more BPM (step S10).

In the confirmation in step 10, when the music data MD of the original BPM music M that meets the conditions related to the step S10 is recorded in the recording unit 6 (step S10; YES), the control unit S selects the corresponding music M. The music identification data to be identified is added to the reproduction list PL (step S11), and then the control unit S determines whether or not the required number of music M is described in the reproduction list PL (step S12). When the required number of songs M are described in the playlist PL in the determination in step S12 (step S12; YES), the control unit S moves to step S6 described later.

On the other hand, in the confirmation in the step S10, when the music data MD of the original BPM music M that meets the conditions related to the step S10 is not recorded in the recording unit 6 (step S10; NO), or necessary in the determination in the step S12. When a number of songs M are not described in the playlist PL (step S12; NO), the control unit S relaxes the condition related to step S7 and extracts the target BPM in order to extract a more appropriate song M. Whether or not the song data MD of the song M to which the original BPM belongs is recorded in the recording unit 6 within a range from 30% less BPM to 20% more BPM, centering on half (Tbpm / 2) (Step S13).

In the confirmation in step 13, when the music data MD of the original BPM music M that meets the conditions related to the step S13 is recorded in the recording unit 6 (step S13; YES), the control unit S selects the corresponding music M. The music identification data to be identified is added to the reproduction list PL (step S14), and then the control unit S moves to step S6.

On the other hand, when the song data MD of the song B of the original BPM that meets the conditions related to the step S13 is not recorded in the recording unit 6 in the confirmation in the step S13 (step S13; NO), the target BPM at the present time is more than this Assuming that the music piece M cannot be extracted, the processing returns to step S1 and the processing after step S1 is executed again.

As a result of the execution of the playback preparation process according to the above embodiment, the playback list PL describes the music M to be played from the music player P and the playback order thereof in the exercise to be performed later.

Next, BPM control when the exercise rhythm according to the embodiment is increased using the playlist PL generated by the reproduction preparation process according to the embodiment will be specifically described with reference to FIGS. 6 and 7. . Note that the control of the BPM according to the above embodiment increases the exercise rhythm corresponding to the load data LD at the stage where the music M based on the reproduction list PL recorded in the recording unit 6 has already been reproduced. To be done.

In addition, in FIG. 6 and FIG. 7 and the following description, the target exercise rhythm (in other words, the load itself) at that time is appropriately indicated as “target rhythm”. The exercise rhythm at this time corresponds to, for example, the number of steps per minute when the exercise to be performed is jogging, and corresponds to the timing of the vertical movement of the weight per minute when the exercise to be performed is weight training. To do.

In FIGS. 6 and 7 and the following description, the BPM that is the next target (next target) corresponding to the target rhythm is appropriately indicated as “next target BPM” or “N_Tbpm”. “N” in this case means the next. Further, in FIGS. 6 and 7 and the following description, the BPM of the song M at that time is appropriately indicated as “Cur_bpm”. In this case, “Cur_” means current.

Furthermore, “master tempo processing” in FIGS. 6 and 7 and the following explanation is such that, in the reproduction control of the song M, the key (pitch) does not change even if the tempo (BPM) of the song M is changed. It is a process to reproduce. In the master tempo process described below, the original BPM of the tune M is changed toward the next target BPM (N_Tbpm) within a range where the key is not changed. According to this master tempo process, even if the BPM of the song M changes, the key does not change, so that it is difficult for the listener to feel uncomfortable. The master tempo process according to the embodiment itself can be realized by a method similar to the conventional one. However, as the master tempo process according to the embodiment, the master tempo process is performed in order to suppress a sense of discomfort in the exerciser as much as possible. Is performed so that the original BPM of the song M to be subject to the change is lower than the median of the changeable range by the master tempo process (for example, the range of 35% BPM in the vertical direction) (see FIG. 7 described later).

Specifically, in the BPM control in the case of increasing the exercise rhythm according to the embodiment, the control unit S sets the target rhythm at that time corresponding to the load data LD illustrated in FIG. 3A (step S20). In addition, based on the set target rhythm, the next target BPM at that time is calculated (step S21).

Next, the changing unit 2 of the control unit S determines whether or not the next target BPM calculated in step S21 is smaller than 25% more BPM than Cur_bpm (step S22). The determination in step S22 determines whether or not Cur_bpm can be increased to the next target BPM calculated in step S21 if the master tempo process according to the embodiment is executed for the currently reproduced song M. It is processing to do. In the determination of step S22, when the next target BPM calculated in step S21 is smaller than BPM that is 25% more than Cur_bpm (step S22; YES), the changing unit 2 is currently reproduced by controlling the reproduction output unit 10. A master tempo process for increasing the BPM is performed for the existing music M (step S23). As a result, the BPM of the currently played song M gradually increases toward the next target BPM, and accordingly, the consciousness of the implementer listening to the song M increases the motor rhythm. Will work in the direction. Thereafter, the changing unit 2 determines whether or not Cur_bpm has reached the next target BPM (step S24). If not, the changing unit 2 returns to step S23 and continues to execute the master tempo process (step S24; NO). To do. On the other hand, when Cur_bpm has reached the next target BPM in the determination in step S24 (step S24; YES), the control unit S determines whether or not to continue the increase even if the current exercise rhythm has ended. Step S25). The determination in step S25 is performed, for example, by determining whether it is necessary to set another next target BPM corresponding to the load data LD.

When it is not necessary to continue the movement rhythm increase in the determination in step S25 (step S25; NO), the control unit S ends the control of the BPM for the movement rhythm increase, and the current Cur_bpm causes the music M to be updated. Continue playback. On the other hand, if it is necessary to continue to increase the exercise rhythm in the determination in step S25 (step S25; YES), the changing unit 2 of the control unit S sets the changed BPM as Cur_bpm by the master tempo process in step S23 (step S26). ), Returning to step S21, the above-described processing is repeated.

Here, regarding the change in BPM when the processing of Step S20 to Step S24 is performed (in other words, when the next target BPM is smaller than BPM 25% larger than Cur_bpm (see Step S22; YES)), This will be specifically described with reference to FIG. In the case illustrated in FIG. 7A, if the song Mn is currently being reproduced, the next target BPM is within the controllable range An by the master tempo process (dotted line in FIG. 7A). reference). Therefore, the changing unit 2 gradually increases Cur_bpm as the BPM of the music Mn at a speed corresponding to the load data LD indicated by the one-dot chain line in FIG. 7A (refer to Step S23 and Step S24 in FIG. 6; NO). Then, when Cur_bpm reaches the next target BPM (see step S24 in FIG. 6; YES), the reproduction of the song Mn is continued with the next target BPM (with the key unchanged) thereafter (FIG. 7A). (See dashed arrow). In FIG. 7, the thick solid line indicates the original BPM of each song M.

On the other hand, if the next target BPM calculated in step S21 is equal to or greater than 25% more than Cur_bpm in the determination in step S22 (step S22; NO), the currently played music even if the master tempo process is performed In the range of M, Cur_bpm cannot be increased to the next target BPM. Accordingly, the changing unit 2 next determines whether or not the next target BPM calculated in step S21 is smaller than the BPM that is 25% more than the BPM that is 25% more than the Cur_bpm (step S27). In the determination in step S27, Cur_bpm can be increased to the next target BPM calculated in step S21 if the master tempo process according to the embodiment is executed for the music M next to the music M currently being reproduced. This is a process for determining whether or not. When the next target BPM calculated in step S21 satisfies the condition related to step S27 in the determination in step S27 (step S27; YES), the changing unit 2 next changes the next target BPM at that time by the master tempo process. The recording unit 6 searches the recording unit 6 for a song M that falls within the range of possible BPM, selects it as the song M to be played next to the current song M, and updates the playlist PL accordingly (step S28). The music piece M to be reproduced next selected in step S28 is hereinafter simply referred to as “next music M”.

Next, the changing unit 2 performs a master tempo process for increasing the BPM for the currently reproduced song M by controlling the reproduction output unit 10 (step S29). As a result, the BPM of the currently played song M gradually increases toward the connection to the next song M, and accordingly, the consciousness of the practitioner who is listening to the song M is the exercise rhythm. Will work in the direction of up. Thereafter, the changing unit 2 determines whether Cur_bpm has approached the upper limit of the changeable range by the master tempo process for the current song M (step S30). If Cur_bpm is not approaching the upper limit of the changeable range for the current song M in step S30 (step S30; NO), the change unit 2 returns to step S29 and continues to perform master tempo processing for the current song M. Execute. On the other hand, when Cur_bpm approaches the upper limit of the changeable range for the current song M in step S30 (step S30; YES), the changing unit 2 and the output control unit 3 are the mixing unit 10C of the reproduction output unit 10, etc. To control the crossfade between the end portion of the currently reproduced song M and the beginning portion of the next song M selected in step S28, and transfer the playback target to the next song M. (Step S31).

Next, the changing unit 2 performs a master tempo process for increasing the BPM for the next music piece M that is currently reproduced by controlling the reproduction output unit 10 (step S32). As a result, the BPM of the next music M being reproduced gradually increases toward the next target BPM (see step S27; YES and step S28), and accordingly, the next music M is being listened to. The consciousness of the practitioner will work in the direction of improving the motor rhythm. Thereafter, the changing unit 2 determines whether or not Cur_bpm of the next song M has reached the next target BPM (step S32). If not, the change unit 2 returns to step S32 to return to the next song. The master tempo process is continued for M. On the other hand, if it is determined in step S32 that Cur_bpm of the next song M has reached the next target BPM (step S32; YES), the control unit S moves to step S25 and performs the subsequent processing.

Here, when the processing of step S27 to step S32 is performed (in other words, when the next target BPM is smaller than the BPM that is 25% more than the Cur_bpm and 25% more than the BPM (see step S27; YES)). The change in BPM will be described more specifically with reference to FIG. In the case illustrated in FIG. 7B, if the song Mn is currently being reproduced, the next target BPM is not included in the controllable range An by the master tempo process for the song Mn, and the next song Mn + 1 It is within the controllable range An + 1 by the master tempo process (see dotted line in FIG. 7B). Therefore, the changing unit 2 gradually increases Cur_bpm from the music Mn to the next music Mn + 1 at a speed corresponding to the load data LD indicated by the one-dot chain line in FIG. (See step S29, step S31, and step S32 in FIG. 6), and then when Cur_bpm of the next song Mn reaches the next target BPM (see step S32 in FIG. 6; YES), then (the key remains unchanged) The reproduction of the song Mn + 1 is continued with the next target BPM (see the broken line arrow in FIG. 7B).

On the other hand, if the next target BPM calculated in step S21 does not satisfy the condition related to step S27 in the determination in step S27 (step S27; NO), the master M tempo process currently played back and the next scheduled playback Even if applied to the song M, Cur_bpm cannot be increased to the next target BPM. Therefore, the changing unit 2 searches the recording unit 6 for the music M whose next target BPM at that time is within the range of BPM that can be changed by the master tempo process, and is currently played back with the music M to be searched. The connecting music M for connecting the current music M is also searched in the recording unit 6, and the connecting music M is selected as the music M to be reproduced after the current music M, and the next target BPM at that time is The song M that falls within the range of BPM that can be changed by the master tempo process is selected, and the playlist PL is updated accordingly (step S33).

Next, the changing unit 2 performs a master tempo process for increasing the BPM for the currently reproduced song M by controlling the reproduction output unit 10 (step S34). As a result, the BPM of the currently played song M gradually increases toward the connection to the next song M, and accompanying this, the consciousness of the practitioner who is listening to the song M is exercising. It will work in the direction of improving the rhythm. Thereafter, the changing unit 2 determines whether or not Cur_bpm has approached the upper limit of the changeable range by the master tempo process for the current song M (step S35). If Cur_bpm is not close to the upper limit of the changeable range for the current song M in the determination in step S35 (step S35; NO), the changing unit 2 returns to step S34 and continues the master tempo process for the current song M. Execute. On the other hand, when Cur_bpm approaches the upper limit of the changeable range for the current song M in step S35 (step S35; YES), the changing unit 2 and the output control unit 3 are the mixing unit 10C of the reproduction output unit 10, etc. To control the crossfade between the end portion of the currently playing song M and the beginning portion of the connecting song M selected in step S33, and transfer the playback target to the next song M. (Step S36).

Next, the changing unit 2 controls the reproduction output unit 10 to perform master tempo processing for increasing the BPM for the joint music M currently being reproduced (step S37). As a result, the BPM of the connected piece M being reproduced gradually increases toward the next target BPM corresponding to the subsequent pieces of the subsequent piece M (see step S27; NO and step S33). The consciousness of the practitioner who is listening to the connecting piece M works in the direction of improving the movement rhythm. Thereafter, the changing unit 2 determines whether or not the reproduction of the connecting piece M has been completed (step S38). If it is determined in step S38 that the connecting piece M has not ended (step S38; NO), the control unit S returns to step S34 and sequentially executes steps S34 to S37 for the connecting piece M. At this time, when there are a plurality of connecting songs M, the above steps S34 to S37 are executed for each connecting song M in the reproduction order.

On the other hand, if it is determined in step S38 that all connected songs M have been reproduced (step S38; YES), then the changing unit 2 selects the next target BPM at that time selected in step S33 as the master. It is determined whether or not Cur_bpm of the song M within the range of BPM that can be changed by tempo processing has reached the next target BPM (step S39). If not reached (step S39; NO), step S37 is performed. Returning to FIG. 4, the master tempo process and the determination in step S39 are continued for the music M selected in step S38. On the other hand, if it is determined in step S39 that Cur_bpm of the song M selected in step S38 has reached the next target BPM (step S39; YES), the control unit S moves to step S25 and performs the subsequent processing.

Here, when the processing of step S33 to step S39 is performed (in other words, when the next target BPM is 25% more BPM than 25% more than Cur_bpm (see step S27; NO)) The change in BPM will be described more specifically with reference to FIG. FIG. 7C illustrates the case where the joint music M is only music Mn + 1. In the case illustrated in FIG. 7C, if the song Mn is currently being reproduced, the next target BPM is not in the controllable range An by the master tempo process for the song Mn, and the connecting song Mn + 1 is This is beyond the controllable range An + 2 by the master tempo process for the music Mn + 2 selected in step S38 (see the dotted line in FIG. 7C). For this reason, the changing unit 2 gradually increases Cur_bpm from the curvature Mn to the curvature Mn + 2 while interposing the crossfade process at a speed corresponding to the load data LD indicated by the one-dot chain line in FIG. When the Cur_bpm of the last song Mn + 2 reaches the next target BPM (see step S39; YES in FIG. 6) after that (see step S39 in FIG. 6, YES), then (the key remains unchanged) The reproduction of the song Mn + 2 is continued with the next target BPM (see the broken line arrow in FIG. 7C).

In the above-described embodiment, the control of the BPM when the exercise rhythm according to the embodiment is raised has been described. However, when the exercise rhythm according to the embodiment is lowered, the condition relating to the determination of step S22 is “step”. It is changed to “determine whether or not the next target BPM calculated in S21 is larger than the BPM 10% less than Cur_bpm”, and the condition relating to the determination in step S27 is “the next target BPM calculated in step S21 is based on Cur_bpm” Is also determined to be greater than 10% less BPM than 10% less, and the conditions relating to the determination in step S30 and the determination in step S35 are “Cur_bpm is the master tempo for the current song M,” respectively. To determine whether or not the lower limit of the range that can be changed by the process is approached ", and each master tempo process ( Step S23, step S29, step S32, may be the step S34 and step S37) in the gradually lowering constituting the BPM.

As described above, according to the reproduction preparation process and the BPM control in the music player P according to the embodiment, the load data LD indicating the relationship between the load (exercise rhythm) corresponding to the predetermined exercise plan and the exercise time is obtained. Based on this, the content (specifically, BPM) of the song M output to the practitioner is changed to BPM corresponding to the load corresponding to the exercise time and reproduced. Therefore, the practitioner can recognize the load applied to himself / herself in relation to the exercise plan that should be the target, so that the exerciser can effectively perform the exercise according to the exercise plan. .

In addition, since the BPM in the music M is controlled based on the BPM indicating the characteristics of each music M and the load data LD, the music M is reproduced in a state in which the exercise person can easily recognize the load more sensuously. can do.

Further, the song data MD is acquired from the recording unit 6 for recording the song data MD corresponding to the selected song M, and the BPM of the song M corresponding to the song data MD is controlled, so that the song data MD is recorded in advance. It is possible to effectively perform the exercise according to the exercise plan by using the song M.

Furthermore, when the exercise rhythm is increased, a song M whose original BPM before and after the increase is lower than the BPM corresponding to the load data LD is selected (see pattern 1-1 or pattern 1-2 in FIG. 4). ), When the exercise rhythm is increased, the exerciser can control the BPM of the music M without a sense of incongruity, and the change of the load can be recognized by the operator.

On the other hand, when lowering the exercise rhythm, music that is higher than the BPM corresponding to the load is selected for both the original BPM before and after the down (see pattern 1-2 or pattern 2-2 in FIG. 4). When the exercise level is lowered, the practitioner can control the BPM of the song M without a sense of incongruity, and can make the practitioner recognize the change in load.

When the exercise rhythm is lowered, the music M whose original BPM before the down is half of the BPM corresponding to the load may be selected (see pattern 3-1 or pattern 3-2 in FIG. 4). . Also in this case, the implementer can control the BPM of the music piece M without a sense of incongruity, and can make the implementer recognize the change in load. The original BPM of the song M selected at this time is not limited to one-half of the BPM corresponding to the load, but according to the tone of the song M, 1 / n of the BPM corresponding to the load (where n is 3 or more) Natural number).

Further, in the reproduction preparation process and the master tempo process according to the embodiment, when the song M having the original BPM within the predetermined BPM range including the BPM corresponding to the load data LD is selected, the center of the BPM range is selected. The value is made smaller than the BPM corresponding to the load data LD (see FIGS. 4 and 7). Therefore, BPM control corresponding to the load data LD can be performed without a sense of incongruity.

Furthermore, when the BPM of the song M is controlled in response to the change of the load data LD, the median of the changeable range by the master tempo process is changed to be larger than the original BPM of the song M (FIG. 7). , The median of the controllable range An to the controllable range An + 2 for each song M is larger than the original BPM (see the thick solid line)), and the BPM corresponding to the load data LD is more comfortably performed. Can do.

In the reproduction preparation process according to the above-described embodiment, the music M to be reproduced and the reproduction order thereof are determined as the reproduction list PL before the exercise is performed, but other than this, for example, a sensor or the like (not shown) is used. It is determined whether or not the exercise is smoothly performed, and if it is smooth, the reproduction is performed in the state described in the playlist PL, and the exercise does not follow the original exercise plan due to poor physical condition or the like. If it is, the playback in the order described in the playlist PL is temporarily stopped, and the exercise plan (up / down of the exercise rhythm) is manually performed by the practitioner while checking the situation and physical condition each time. The playlist PL may be generated again based on the load data LD indicating the exercise plan after the change.

Further, as specific values of the changeable range (upper limit + 25% and lower limit −10%) by the master tempo processing according to the embodiment, basically, the amount of change in a range that does not deviate very much from the original BPM (in other words, implementation) The amount of change in a range that does not cause a sense of incongruity even if the person listens to the music M after the control of the BPM), and thus these ranges may be configured to be changeable by the practitioner.

Furthermore, in addition to the music M according to the embodiment, for example, by controlling the playback speed of moving images or the continuous playback of still images according to the load data LD, the exercise rhythm according to the embodiment can be controlled. You may comprise so that the increase / decrease in may be recognized.

In addition, a program corresponding to the flowcharts shown in FIGS. 5 and 6 is recorded in a recording medium such as an optical disk or a hard disk, or obtained via a network such as the Internet, and this is used as a general-purpose microcomputer. It is also possible to cause the microcomputer or the like to function as the control unit S and the reproduction output unit 10 according to the embodiment.
