The method for marking the beat provided by this embodiment will be described in detail below in conjunction with FIG. 1 and FIG. 2.

FIG. 2 is a flowchart of a beat marking method according to a first embodiment of the present invention. Please refer to FIG. 1 and FIG. 2 at the same time. In step S201, the beat marker module 123 determines whether to obtain the rhythm speed of the music through the music file. Specifically, as described above, the music library 121 has a plurality of music files. The beat marker module 123 may read the music files to obtain the rhythm speed of the music of each music file, or the beat marker module 123 may read the music files to calculate the rhythm speed of the music of the music files. The unit of the rhythm speed is Beats per minute (BPM). The method of how to obtain the tempo of music in this embodiment will be described below with reference to FIG. 3.

FIG. 3 is a flowchart illustrating obtaining a rhythm speed of music through a music file according to a first embodiment of the present invention. Please refer to FIG. 1 and FIG. 3 at the same time. In step S2011, the beat marker module 123 determines whether there is rhythm speed information in the music file corresponding to the music. For example, the beat marker module 123 can read a music file, and can recognize that the music file has embedded or built-in rhythm speed information, wherein the rhythm speed information is used to indicate the rhythm speed of the corresponding music. In addition, if the music has multiple tempo speeds at different playback times, the tempo speed information corresponding to the music will record multiple tempo speeds corresponding to different playback times. If in step S2011, the beat marker module 123 recognizes (determines) that the music file has rhythm speed information, then proceed to step S2013, and the beat marker module 123 will obtain the rhythm speed of the music according to the rhythm speed information .

If in step S2011, the beat marker module 123 recognizes (determines) that the music file has no rhythm speed information, then proceed to step S2015, and the beat marker module 123 determines whether the rhythm speed of the music is available. Obtained through calculation. Specifically, the beat marker module 123 reads and analyzes the music file to identify the distribution of the strong beat of the music file corresponding to the playback, and then calculates the distribution based on the distribution of the strong beat of the music. Describe the tempo of the music (eg, the average number of beats per minute). For the manner of calculating the rhythm speed of music, reference may be made to the current prior art, and details are not described herein.

If in step S2015, the beat marker module 123 determines that the rhythm speed of the music cannot be obtained through calculation (for example, the strong beat of the music is randomly distributed), it will determine that the music rhythm is not obtained through the music file speed. In the following, other embodiments (for example, the third and fourth embodiments) will be described to explain the corresponding operation if the music file cannot be obtained through the music file.

If in step S2015, the beat mark module 123 determines that the rhythm speed of the music can be obtained through calculation (for example, the strong beat of the music has a certain law and appearance), proceed to step S2017, the beat mark The module 123 obtains the tempo of the music through calculation. It is worth mentioning that after steps S2013 and S2017, the beat marker module 123 determines that the rhythm speed of the music is obtained through the music file, and proceeds to step S2051.

Returning to FIG. 2 again, in step S203, the beat marking module 123 selects a preset beat audio and a beat speed corresponding to the preset beat audio according to the rhythm speed. In this embodiment, the beat marking module 123 selects a preset beat audio according to a manufacturer setting. In addition, the beat marker module 123 sets (selects) a beat speed equal to the beat speed according to the beat speed to correspond to the selected preset beat audio. In another embodiment, the beat marking module 123 may provide a user with multiple beat audio and beat speed options, and select a preset beat audio and corresponding beat speed according to the user's selection. The method of selecting a preset tempo audio and a tempo corresponding to the preset tempo audio will be described in the following embodiments.

In step S205, the beat marking module 123 marks the preset beat audio to the music according to the beat speed and the rhythm speed. Specifically, the beat marker module 123 will align the preset beat audio with the speed of the adjusted beat speed V _B to align with the strong beat of the music for playback according to the appearance time of the strong beat of the music. That is, since the adjusted tempo V _B is equal to the rhythm speed of the music and the rhythm speed of the music will correspond to the appearance time of the strong beat of the music. Therefore, when a strong beat of music appears, the preset beat audio marked to the music also appears at the same time.

Next, in step S207, the beat marking module 123 instructs the audio playback unit 130 to play the music and the preset beat audio marked to the music at the same time. For example, the beat marker module 123 sends information about the adjusted beat speed, the relationship between the preset beat music and the music, the preset beat music, and the music to the audio playback unit 130 so that The audio playback unit 130 can simultaneously play the music and the preset beat audio marked to the music.

[Second embodiment]

FIG. 4 is a flowchart of a tempo marking method according to a second embodiment of the present invention. Steps S401 and S413 in FIG. 4 are the same as steps S201 and S207 in FIG. 2, and the electronic device and corresponding components used to implement the beat marking method in the second embodiment are the same as those in the first embodiment, and the relevant details are not repeated here. .

Referring to FIG. 4, in step S403, the beat marking module 123 determines whether the rhythm speed must be restricted. For example, if the user wants to filter out the music that is suitable for the activity currently being performed, the user may notify the user of the beat marking module 123 by a button or a trigger option. In this way, the beat marking module 123 determines that the rhythm speed of the music needs to be limited. Or, in another embodiment, the manufacturer may preset to limit the rhythm speed of the music.

In this embodiment, after the beat marker module 123 determines that it is necessary to limit the rhythm speed of the music, the beat marker module 123 also filters multiple music from multiple music files in the music database 121, so that the filtered music is Music suitable for the activity, and the tempo of the filtered music will be limited to the target speed interval. In addition, in an embodiment, the user may also independently select the rhythm speed to be listened to, so that the beat marking module 123 limits the rhythm speed (or, filters out music corresponding to the rhythm speed selected by the user).

If in step S403, the beat marking module 123 determines that the tempo needs to be restricted, and continues to step S405, the beat marking module 123 determines whether the beat speed is within the target speed range.

For example, suppose the user wants to perform an activity, so that the beat marker module 123 can set a target speed interval according to the activity that the user wants to perform, thereby limiting the rhythm speed of the music. The beat marker module 123 can provide multiple options for the user to select the current activities to be performed, such as jogging, fast running, walking, etc., and the beat marker module 123 can be set to correspond to different activities to set different Target speed range. The target speed interval is a speed interval between a speed upper limit value V _H (in BPM) and a speed lower limit value V _L (in BPM). Then, the beat marker module 123 determines whether the rhythm speed of the music (for example, the music to be currently played) is within the target speed interval according to the activity or the target speed interval selected by the user.

If the rhythm speed is within the target speed interval, proceeding to step S407, the beat marking module 123 adjusts the beat speed to the adjusted beat speed according to the rhythm speed, wherein the adjusted beat speed is equal to the adjusted beat speed. Said rhythmic speed.

Specifically, if the rhythm speed is within the target speed interval, the beat marker module 123 will select one beat audio as a preset beat audio from a plurality of beat audios in the beat audio database, and obtain a corresponding beat audio. The tempo of the beat audio. For example, suppose that the rhythm speed V _O of the music to be played (selected) is 150 beats per minute (hereinafter referred to as "150 BPM"), the preset beat audio is drum sound, and the corresponding beat speed V _B is "140 BPM." The beat marker module 123 adjusts the beat speed of the preset beat audio from the original beat speed V _B to the adjusted beat speed V _B ', and the speed of the adjusted beat speed V _B ' is equal to a rhythm speed of "150 BPM" The speed of V _O (ie, the adjusted tempo V _B '= rhythmic speed V _O ).

After adjusting the tempo corresponding to the preset tempo audio, in step S411, the tempo marking module 123 marks the preset tempo audio to the music according to the adjusted tempo. Then, proceed to step S413, where the description of step S413 is the same as step S207, and will not be repeated here.

If in step S405, the beat marker module 123 determines that the tempo speed is not within the target speed range, proceeding to step S409, the beat marker module 123 will adjust the beat speed to the adjusted beat speed according to the beat speed. . What is different from step S407 is that the adjusted tempo in step S409 is not adjusted according to the rhythm speed. The method of adjusting the tempo in step S409 will be described below with reference to FIG. 5.

FIG. 5 illustrates a method for adjusting a tempo according to a second embodiment of the present invention. Referring to FIG. 5, in step S4091, the beat marking module 123 determines whether the rhythm speed is less than the target speed interval. Specifically, because the rhythm speed is not within the target speed interval, the beat marking module 123 determines whether the rhythm speed is greater than the speed upper limit value V _{H of} the target speed interval or the rhythm speed is less than the target speed interval. Lower speed limit V _L.

If the beat marking module 123 determines that the rhythm speed is less than the target speed interval (for example, the rhythm speed is less than the speed lower limit value V _{L of the} target speed interval), in step S4093, the beat marking module 123 will The tempo adjustment is a product obtained by multiplying the rhythm speed by a first constant, wherein the first constant is obtained by dividing the lower limit value of the speed of the target speed interval by the rhythm speed. For example, assume that the tempo is “V _B ”, the tempo is “V _O ”, the first constant is “N _L ”, and the lower limit of the tempo is “V _L ”. A formula for the first constant is obtained, that is, N _L = V _L / V _O. It should be noted that, in this embodiment, the first constant is also integerized (however, the minimum value after integerization is limited to "1"). For example, using a method such as unconditional rounding, rounding to an integer, and unconditional rounding to perform integerization on the quotient obtained by dividing the speed lower limit value V _L by the rhythmic speed V _O as the first constant N _L. Then, the tempo is adjusted to a product obtained by multiplying the rhythm speed by a first constant (that is, V _B '= V _O * N _L ). For example, assume that the tempo is "100 BPM", the tempo is "20 BPM", the first constant is "N _L ", the lower speed limit is "60 BPM", and the upper speed limit is "180 BPM". In addition, the method of integerization is assumed to be an unconditional carry. In this example, the rhythm speed is less than the lower speed limit (20 <60). Therefore, the first constant N obtained from the formula (V _L / V _O = 60/20 = 3) and the integer method is used. _L will be "3" and the adjusted tempo will be "60 BPM" (20 * 3 = 60).

If the beat marking module 123 determines that the rhythm speed is not less than the target speed interval (for example, the rhythm speed is greater than the speed upper limit value V _{H of the} target speed interval), in step S4095, the beat marking module 123 will The tempo adjustment is a quotient obtained by dividing the rhythm speed by a second constant, wherein the second constant is obtained by dividing the rhythm speed by a speed upper limit value of the target speed interval. For example, it is assumed that the tempo is “V _B ”, the tempo is “V _O ”, the second constant is “N _H ”, and the upper limit of the tempo is “V _H ”. A formula for the second constant is obtained, that is, N _H = V _O / V _H. It should be noted that, in this embodiment, the second constant is also integerized (however, the minimum value after integerization is limited to "1"). For example, the value obtained by integerizing the quotient obtained by dividing the rhythmic speed V _O by the speed upper limit value V _H is used as the second constant by using integer methods such as unconditional rounding, rounding to round integers, and unconditional carry N _H. Then, the tempo is adjusted to a quotient obtained by dividing the tempo by a second constant (ie, V _B '= V _O / N _H ). For example, assume that the tempo is "100 BPM", the tempo is "240 BPM", the second constant is "N _H ", the lower limit value is "60 BPM", and the upper limit value is "180 BPM". In addition, the method of integerization is assumed to be an unconditional carry. Because in this example, the tempo is greater than the upper speed limit (240> 180), the formula (V _O / V _H = 240/180 = 1.3) and the integer method ("1.3" unconditional rounding becomes "2") The second constant N _{H obtained} will be "2", and the adjusted tempo will be "120 BPM" (240/2 = 120).

It is worth mentioning that manufacturers can set other calculation methods of the first and second constants according to their own requirements, so that the calculated first and second constants will become positive integers after calculation. For example, in another embodiment, taking the first constant as an example, the method of integerization of the first constant may be further set to "plus 1 if the unconditional carry meets an odd number". For example, assume that the tempo is "100 BPM", the tempo is "20 BPM", the first constant is "N _L ", the lower speed limit is "60 BPM", and the upper speed limit is "180 BPM". In addition, it is also assumed that the method of integerization is unconditional carry and "plus 1 if the unconditional carry meets an odd number". In this example, the first constant N _L obtained through the above formula (V _L / V _O = 60/20 = 3) and the integer method will be “3”, so the first constant will be more The calculation becomes "4" (3 + 1 = 4), and the adjusted tempo will be "60 BPM" (20 * 4 = 80). It should be noted that the method of integerizing the first constant and the second constant also includes the above-mentioned integerization method (for example, unconditional rounding, unconditional rounding, rounding), plus "subtract 1 by odd numbers""Add 1 if you encounter an even number" or "Minus 1 if you encounter an even number". However, the minimum value must be limited to 1.

After completing the step of adjusting the tempo to the adjusted tempo performed in step S409, steps S411 and S413 are continued, and the description of steps S411 and S413 will not be repeated here. Based on the above, steps S203 and S205 in the first embodiment can be more specifically performed through steps S403 to S411 (such as the dotted lines in FIG. 4) of the second embodiment.

It is worth mentioning that, in another embodiment, step S403 can be omitted. For example, after step S401, the beat marker module 123 obtains the rhythm speed of the music, the beat marker module 123 may directly execute step S405 to determine whether the rhythm speed is within a target speed interval, where the target speed interval may be a system preset Set the speed zone or the speed zone selected by the user.

It should be noted that if in step S403, the beat marker module 123 determines that it is not necessary to limit the tempo, proceeding to step S407, the beat marker module 123 will select the preset beat audio and the corresponding beat audio. A tempo, and the tempo is adjusted to an adjusted tempo according to the tempo, wherein the adjusted tempo is equal to the tempo. That is, if there is no need to limit the tempo, for example, the user does not select the desired activity, the beat marking module 123 will adjust the beat speed of the preset beat audio to the original corresponding preset beat audio to music. With the same tempo, and the preset beat audio is marked to the music according to the tempo.

In the second embodiment. The third embodiment is different from the second embodiment in that, in step S601, if the beat marker module 123 does not obtain the rhythm speed of the music via the music file (for example, the music file does not have embedded or built-in rhythm speed information, and (It is not possible to calculate the rhythm speed of the corresponding music through the music file), proceeding to step S615, the beat marking module 123 determines whether a forced marking operation needs to be performed. Specifically, the manufacturer can set whether to perform a forced marking operation in advance, or the user can choose whether to perform a forced marking operation. The compulsory marking operation is to forcibly mark a preset beat audio to the music without considering the rhythm speed of the music to play the music and the preset beat audio at the same time.

If a forced marking operation needs to be performed, in step S617, the beat marking module 123 selects a preset beat audio and a beat speed corresponding to the preset beat audio. For example, in one embodiment, the user may select a beat audio from a plurality of beat audios in the beat audio database as a preset beat audio, and the user may set a corresponding beat speed. For another example, the user may select an activity to be performed, and the beat marking module 123 may select an appropriate preset beat audio and beat speed according to the activity selected by the user.

In step S619, the beat marking module 123 marks the selected preset beat audio to the music according to the beat speed. Specifically, after selecting the preset beat audio and the corresponding beat speed, the beat marking module 123 will force (directly) mark the preset beat audio to the music. Finally, following step S613, the beat marking module 123 instructs the audio playback unit to simultaneously play the music and the preset beat audio marked to the music. In this way, by forcing the mark operation, the user can listen to the music and the preset beat audio of the mark to the music at the same time regardless of the rhythm speed of the music. For example, when listening to a lecture (audio content that does not have a specific tempo), the user can mark the beat audio with a beat speed that matches the running speed to the speech so that the user can follow the beat audio to listen to the lecture. Run.

The descriptions of steps S801, S811, and S813 in FIG. 8 are the same as the descriptions of steps S201, S211, and S213 in FIG. 2, respectively, and the electronic device used to implement the beat marking method in the fifth embodiment is the same as the corresponding component. In the second embodiment. Hereinafter, other steps of the fifth embodiment will be described in detail with reference to FIGS. 1 and 8.

In step S803, the beat marking module 123 selects a preset beat audio and a beat speed corresponding to the preset beat audio. Specifically, the fifth embodiment provides a method for automatically selecting a preset beat audio and a corresponding beat speed according to a rhythm speed. In this embodiment, the beat marking module 123 identifies the beat audio and beat speed corresponding to each beat audio file from multiple beat audio files in the beat audio database. Next, the beat marker module 123 calculates the difference between the beat speed and the rhythm speed of each beat audio (for example, the absolute value of the difference obtained by subtracting the beat speed from the beat speed), and selects a minimum value among multiple differences. As the preset beat audio. That is, the beat marker module 123 selects the beat audio whose beat speed is closest to the rhythm speed as the preset beat audio. It is worth mentioning that when there are more than two beat audios that meet the selection conditions, they can be filtered by one of the following methods: automatically selecting the faster beat speed; automatically selecting the slower beat speed; the user Manual selection; and automatic random selection.

In addition, as described above, if the music has multiple rhythm tempo, the beat marking module 123 will select a plurality of preset beat audios correspondingly in the manner described above. However, in another embodiment, the beat marking module 123 can mark the music with the same preset beat audio through the beat tempo corresponding to different tempo of a piece of music.

In step S805, the beat marking module 123 determines whether the beat speed is equal to the rhythm speed. If the tempo is not equal to the tempo, in step S807, the tempo marking module 123 determines whether to adjust the tempo. Specifically, the beat marking module 123 may decide whether to adjust the beat speed according to a manufacturer's setting or a user's setting.

If it is determined to adjust the tempo, proceeding to step S809, the tempo marking module 123 adjusts the tempo of the preset tempo audio to an adjusted tempo, wherein the adjusted tempo is equal to the tempo. In other words, the beat marker module 123 adjusts the beat speed corresponding to the preset beat audio to a rhythm speed. If it is determined that the tempo is not adjusted, proceeding to step S815, the tempo marking module 123 tags the preset tempo audio to the music. That is, the beat marking module 123 will mark the beat audio to the music directly according to the beat speed.

In addition, in step S805, if it is determined that the tempo is equal to the rhythm speed, step S815 is also executed.

In the following, the sixth embodiment and corresponding drawings are used to explain how to further apply the beat marking method provided by the present invention.

[Sixth embodiment]

FIG. 9 is a block diagram of an electronic device for implementing a beat marking method according to a sixth embodiment of the present invention. The sixth embodiment has the same components as the first embodiment (such as the processing unit 110, the storage unit 120, the music database 121, the beat audio database 122, the beat marker module 123, and the audio playback unit), and the details are not described again. herein. Only the elements in FIG. 9 that are different from those in FIG. 1 corresponding to the first embodiment will be described below. It is worth mentioning that the sixth embodiment is to explain how to apply the above-mentioned beat marking method to exercise guidance for users.

In this embodiment, the mobile device 100 (also referred to as the electronic device 100) includes a processing unit 110, a storage unit 120, an audio playback unit 130, a detection unit 140, and an exercise plan management unit 150. The processing unit 110 is coupled to the storage unit 120, the audio playback unit 130, the detection unit 140, and the exercise plan management unit 150.

The detection unit 140 is configured to detect a physiological state (for example, exercise heart rate) or an active state (for example, exercise speed) of the user. For example, the detection unit 140 is, for example, a circuit unit that detects a user's exercise heart rate and exercise speed. For another example, the detection unit 140 may sense the heart rate (ie, exercise heart rate) currently performed by the user through a device such as a smart wearable device (or the detection unit 140 itself). For another example, the detection unit 140 is a circuit unit with a global positioning system function, and can calculate the user's movement speed via the global positioning system, or the detection unit 140 can receive other devices that can sense the user's movement speed. The data sent to get the user's speed.

The exercise plan management unit 150 is used to manage and execute the exercise plan, and transmits information corresponding to the executed exercise plan to the processing unit 110 (or the beat marking module 123). The information corresponding to the executed exercise plan includes a target exercise speed. The exercise plan is directed to different sports, and during the execution of the exercise plan, the user is given different exercise instructions according to the time of the period. For example, suppose the exercise plan is an exercise plan (also known as a running plan) for running training. The exercise plan management unit 150 sets the length of the running plan, and gives different running speed instructions (eg, different target exercise speeds) at different time points during the execution of the running plan.

The following will describe in detail the motion guidance using the beat marking method provided by the sixth embodiment in conjunction with FIG. 10 and FIG. 9. It is worth mentioning that the main concept of the sixth embodiment is to provide the user with motion guidance when determining that the user is in a safe motion state, and also provide a safety mechanism in an unsafe motion state. In addition, the way of motion guidance is to adjust the played music or beat audio to make the beat audio more obvious, and then the music and beat audio are played simultaneously through the beat marking method provided by the foregoing embodiment.

FIG. 10 is a flowchart illustrating motion guidance using a beat marker according to a sixth embodiment. Referring to FIG. 10, in step S1001, the beat marking module 123 obtains a target exercise speed corresponding to the exercise plan. For example, the beat marking module 123 may receive the current target exercise speed of the executed exercise plan from the exercise plan management unit 150. Next, in step S1003, the beat marking module 123 limits the rhythm speed of the music according to the target movement speed, and sets the preset beat audio according to the rhythm speed of the music and the beat speed of the preset beat audio. Mark to the music, and then play the music and the preset beat audio marked to the music simultaneously. Specifically, since the exercise plan management unit 150 executes the exercise plan. The exercise plan management unit 150 transmits the corresponding target exercise speed information to the beat marking module 123. Then, the beat marker module 123 determines that the rhythm speed of the music needs to be limited according to the target movement speed. In more detail, the beat marking module 123 may set a target speed interval according to the target movement speed through a table lookup method or the like. For example, the beat marker module 123 can obtain a corresponding target speed interval by querying a conversion table according to the size of the target movement speed (unit: km / h) of each different exercise plan, for example: Beats Per Minute (BPM). In another embodiment, the conversion table can also handle conversions between target exercise heart rate and target speed interval in different units. In other words, with various conversion tables, the beat marking module 123 can also convert target parameters (for example, target exercise speed or target exercise heart rate) of exercise plans of different manufacturers into standardized target speed intervals.

In more detail, the beat marking module 123 can obtain the speed upper limit value and the speed lower limit value of the corresponding target speed section according to the target movement speed, where the speed upper limit value and the speed lower limit value are formed by The range is the target speed interval. In this way, the beat marker module 123 can determine whether the rhythm speed of the music is in the target speed interval, as in the beat marker method of the first to fifth embodiments, so as to correspondingly select or adjust the preset beat audio and the corresponding beat. Speed, and mark preset beat audio to music according to the beat speed, and then play the music and the preset beat audio marked to the music at the same time.

Next, in step S1005, the detection unit 140 detects the exercise heart rate and the exercise speed of the user. Specifically, in the embodiment, during the execution of the exercise plan, the detection unit 140 transmits the detected information of the exercise heart rate and exercise speed of the user to the beat marking unit 123 and the exercise plan management unit 150. It is worth mentioning that the detecting unit 140 may continuously detect the user's exercise heart rate and exercise speed periodically according to the tempo (or rhythm speed).

In step S1007, the beat marking unit 123 determines whether the user is in a safe state according to the exercise heart rate. Specifically, the beat marking unit 123 calculates the maximum heart rate of the user, and determines whether the current exercise state of the user is safe (that is, determines whether the user is in a safe state) according to the current exercise heart rate and the maximum heart rate of the user. The maximum heart rate of the user is, for example, a difference obtained by subtracting the physiological age of the user from 220. In one embodiment, the maximum heart rate can be multiplied by different percentages to obtain the exercise intensity that the user can withstand, so as to determine the safe exercise time that the user can withstand under different exercise intensity.

For example, suppose the user's physiological age is 30, the calculated maximum heart rate is 190 BPM, the maximum training intensity is 100% of the maximum heart rate, and the safe continuous exercise time under the maximum training intensity is 45 seconds. If the user's current exercise heart rate is above 190 BPM for 45 seconds, the beat marker module 123 determines that the user is not in a safe state. It should be noted that the manufacturer can set rules on how to use the exercise heart rate to determine whether the user is in a safe state, and the present invention is not limited thereto.

If it is determined that the user is in a safe state, in step S1009, the beat marking module 123 will determine whether the user's exercise speed matches the user's movement speed according to the user's movement speed and the target movement speed. Exercise plan. Specifically, the beat marking module 123 will continuously determine whether the user's current exercise speed follows the target exercise speed indicated by the exercise plan when the user is in a safe state, so as to determine whether the user has an instruction accompanied by the exercise plan Come exercise. For example, in one embodiment, if the user's movement speed falls within a certain percentage (eg, 5%) of the target movement speed value, the beat marking module 123 determines that the user's movement speed matches the movement plan. However, the present invention is not limited to this, and the manufacturer may formulate rules for determining whether the user conforms to the exercise plan according to other suitable target parameters such as the target exercise speed or the target exercise heart rate indicated by the exercise plan.

In one scenario, the user may be tired and the movement speed is lower than the target movement speed by more than 5%, and the beat marking module 123 may determine that the movement speed of the user does not conform to the exercise plan. In another scenario, the exercise plan may reduce the target exercise speed to half (50%) of the original target exercise speed due to the elapse of exercise time, but the user has not reduced the exercise speed to half of the original exercise speed ( For example, the speed of movement is only reduced to 80% of the original speed). At this time, the beat marking module 123 determines that the user's exercise speed does not conform to the exercise plan.

If it is determined that the user's exercise speed does not conform to the exercise plan, in step S1011, the beat marking module 123 adjusts the music played simultaneously and the preset beat audio marked to the music. Specifically, the beat marker module 123 reduces the volume of the music to emphasize the preset beat audio, so that the user can follow the beat speed of the preset beat audio to exercise, and achieve the effect of motion guidance. Furthermore, in another embodiment, the beat marking module 123 can further enhance the volume of the preset beat audio marked to the music, or increase the characteristics of the preset beat audio (e.g., drum sound) , Piano sounds, etc.) to emphasize preset beat audio.

In addition, in another embodiment, if the beat marker module 123 determines that the user's exercise speed does not conform to the exercise plan, the beat marker module 123 may play beat audio of other beat speeds corresponding to the target exercise speed, so as to perform Exercise guide. In particular, in yet another embodiment, the beat marker module 123 can only play the music, and when the user's exercise speed does not conform to the exercise plan, the beat marker module 123 can play the music and corresponding music at the same time. The beat audio of the target motion speed.

If in step S1009, the beat marking module 123 determines that the user's exercise speed conforms to the exercise plan, the flow returns to step S1001, and the subsequent steps are continued.

If in step S1007, the beat marking module 123 determines that the user is not in a safe state, proceeding to step S1013, the beat marking module 123 will perform an insurance operation. Specifically, since the beat marking method provided by the present invention can adjust the played music and preset beat audio separately. Therefore, the step of performing the insurance operation includes one or a combination of the following steps: stopping playing the music or the preset beat audio; sending out a prompt sound message; and reducing the preset beat audio Beat speed. Wherein, stopping the playing of the music or the preset beat audio can alert the user to the abnormal state of the current exercise; sending out a prompt sound message allows the user to directly know the current exercise status; reducing the preset beat audio The tempo allows the user to perform movements with the reduced tempo, so as to guide the user to reduce the tempo, and then return the user to a safe motion state. It is worth mentioning that after step S1013 or step S1011 is completed, the flow returns to step S1005, and the subsequent steps are continued.

In this way, the motion guidance using the beat marking method provided by this embodiment can be performed without modifying the music itself when specific conditions occur (for example, when the user is not in a safe state or the user does not meet the exercise plan). In the case of the content of the content, the beat audio or the music marked to the music is flexibly adjusted to enhance the user's music listening experience of exercise, and the corresponding exercise plan is performed by setting and adjusting the beat audio and music. Movement guidance, thereby improving the user's exercise efficiency.
