[0002] Vibration waveform processing is a crucial function in modern electronic devices, as high-quality vibration sensing significantly enhances the user experience. With the increasing sophistication of electronic system and application functions, the amount of vibration sensing involved in electronic devices is also growing. In some scenarios, a single electronic device needs to handle multiple vibrations occurring simultaneously, requiring the processing of these multiple vibrations.
[0003] When processing multiple vibrations, most related technologies employ either a method of superimposing and playing multiple vibrations or a method of interrupting each other based on priority. However, these methods all have some drawbacks. For example, the former not only makes the vibration sensations experienced by the user more chaotic, affecting the efficiency of vibration feedback, but the latter not only requires pre-setting the priority of all scenarios with vibration, but also the sudden termination of vibration caused by interruption can create a strong sense of discontinuity in the user experience, similarly affecting the efficiency of vibration feedback.

[0046] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.
[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0048] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. It is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. It should also be noted that the terms "first, second, third" used in the embodiments of this application are merely for distinguishing similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.
[0049] It's understandable that vibration waveform processing is a crucial function in modern electronic devices, as high-quality vibration sensing can significantly enhance the user experience. With the increasing sophistication of electronic device systems and applications, vibration sensing is becoming more and more prevalent. In some scenarios, a single electronic device needs to handle multiple vibrations occurring simultaneously, requiring processing of these vibrations to generate the driving voltage for the final target vibration signal.
[0050] In related technologies, when processing multiple vibrations, most methods employ the method of superimposing and playing multiple vibrations. However, superimposing and playing multiple vibrations not only makes the vibration sensations experienced by the user chaotic, but also affects the efficiency of vibration feedback. Alternatively, different vibrations can be processed by interrupting each other according to priority. This not only requires pre-setting the priority of all scenarios with vibrations, making the program cumbersome and highly dependent on manual intervention, but also the sudden termination of vibrations caused by interruption can create a strong sense of discontinuity in the user experience, similarly affecting the efficiency of vibration feedback.
[0051] In short, current technical solutions are limited and unsuitable for interruption methods in some scenarios. For example, when multiple vibrations are issued simultaneously, it is usually necessary to determine the priority of each scene based on preset scene priorities, allowing higher-priority scene vibrations to interrupt lower-priority scene vibrations. In this case, the priority of all scene vibrations needs to be preset, which is complex and cannot achieve rich mixed vibration sensations.
[0052] Based on this, this application provides a waveform processing method. The basic idea of this method is: to obtain the vibration frequencies corresponding to n conflicting vibration waveforms, where n is an integer greater than or equal to 2; to adjust the vibration frequency of at least one of the n vibration waveforms to obtain a target vibration frequency corresponding to the n vibration waveforms, and the target vibration frequency satisfies a first preset condition; and to superimpose the n vibration waveforms based on the target vibration frequency to generate a target vibration waveform. In this way, by adjusting the frequency of the vibration waveforms, the vibration waveforms can be better superimposed at the target vibration frequency, which not only improves the vibration superposition effect but also achieves a richer mixed vibration sensation. The method proposed in this application, by adjusting the frequency of the original vibration waveforms, can ensure that the vibration of the mixed vibration waveforms is fully realized, resulting in a better vibration superposition effect.
[0053] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0054] In one embodiment of this application, see Figure 1 This illustrates a flowchart of a waveform processing method provided in an embodiment of this application. Figure 1 As shown, the method may include:
[0055] S101: Obtain the vibration frequencies corresponding to the n conflicting vibration waveforms.
[0056] It should be noted that the waveform processing method provided in this application embodiment can be applied to waveform processing devices that require waveform processing, or to electronic devices that integrate such devices. Here, electronic devices can be such as computers, smartphones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, etc., and this application embodiment does not specifically limit them.
[0057] It should also be noted that in the embodiments of this application, there are n kinds of vibration waveforms among the multiple composite vibrations. The vibration frequencies of different vibration waveforms can be the same or different. When the vibration frequencies of at least two waveforms are the same, at least two waveforms can be directly superimposed to obtain a new waveform. Specifically, the peaks can be superimposed to obtain the target waveform with the largest vibration.
[0058] It should also be noted that, in the embodiments of this application, n vibration waveforms may include two, three or more vibration waveforms, that is, n is an integer greater than or equal to 2.
[0059] S102: Adjust the vibration frequency of at least one of the n vibration waveforms to obtain the target vibration frequency corresponding to the n vibration waveforms, and the target vibration frequency satisfies the first preset condition.
[0060] It should be noted that, in the embodiments of this application, the vibration frequency of at least one of the n vibration waveforms is adjusted so that the vibration frequency of the n vibration waveforms meets the target requirements after adjustment, so that the n vibration waveforms can be superimposed subsequently.
[0061] It should also be noted that, in the embodiments of this application, when adjusting the vibration frequency, one or more of the n vibration waveforms can be adjusted. At least one waveform can be adjusted in terms of vibration frequency, and at most, each of the n vibration waveforms can be adjusted in terms of vibration frequency. Specifically, for the vibration waveform whose frequency is adjusted, the adjusted vibration waveform frequency can be used as the target vibration frequency; for the vibration waveform whose frequency is not adjusted, the original vibration waveform frequency can be directly used as the target vibration frequency.
[0062] In some embodiments, the target vibration frequency satisfies a first preset condition, which may include: the target vibration frequencies corresponding to the n vibration waveforms have a least common multiple.
[0063] It should be noted that, in the embodiments of this application, when the vibration frequencies corresponding to the n vibration waveforms have a least common multiple, it can be said that the frequencies of the n vibration waveforms have similar fluctuation characteristics, which can be used to merge them to generate the target vibration waveform.
[0064] In some embodiments, the target vibration frequency satisfying a first preset condition may include:
[0065] The target vibration period corresponding to the n vibration waveforms satisfies the second preset condition; wherein, there is a corresponding relationship between the target vibration period and the target vibration frequency.
[0066] It should be noted that, in the embodiments of this application, the target vibration period needs to be determined by the vibration frequency corresponding to n vibration waveforms. Then, when the target vibration period meets the second preset condition, the envelope approximation between the n vibration waveforms is determined, and they can be superimposed to generate the target vibration waveform.
[0067] It should also be noted that, in the embodiments of this application, the vibration period corresponding to the vibration waveform can be determined by the vibration frequency of the vibration waveform. Specifically, the vibration period T of the vibration waveform is 1 / f, where f is the vibration frequency of the vibration waveform.
[0068] In some embodiments, the target vibration period corresponding to the n vibration waveforms satisfies a second preset condition, which may include: the target vibration period corresponding to the n vibration waveforms has a least common multiple.
[0069] It should be noted that, in this embodiment, the target vibration period needs to be determined by the vibration frequencies corresponding to n vibration waveforms. Then, given that the target vibration period has a least common multiple, the envelope approximation between the n vibration waveforms is determined, and they can be superimposed to generate the target vibration waveform. Specifically, the vibration period of the vibration waveform is T = 1 / f, where f is the vibration frequency of the vibration waveform.
[0070] In some embodiments, the method may further include:
[0071] When the duration corresponding to the least common multiple of the target vibration period is less than or equal to the vibration duration of the conflict zone, the target vibration frequency is determined to meet the first preset condition.
[0072] It should be noted that, in this embodiment, the least common multiple of the target vibration period is compared with the vibration duration of the conflict area. If the target vibration period is less than or equal to the vibration duration of the conflict area, and the periodicity of the n vibration waveforms is determined to be relatively consistent, without any continuous weakening of each other, the n vibration waveforms can be superimposed to generate the target vibration waveform. Here, "consistent" can mean completely consistent or approximately consistent. For the periodicity of the n vibration waveforms to be relatively consistent, it can mean that the periodic errors between the n vibration waveforms are all within a preset range.
[0073] In some embodiments, after obtaining the vibration frequencies corresponding to the n conflicting vibration waveforms, the method may further include:
[0074] Determine the vibration period corresponding to the n vibration waveforms;
[0075] If the duration corresponding to the least common multiple of the vibration period is less than or equal to the vibration duration of the conflict zone, the vibration frequency corresponding to the n vibration waveforms is directly determined as the target vibration frequency.
[0076] It should be noted that, in the embodiments of this application, the vibration period corresponding to the vibration waveform can be determined by the vibration frequency of the vibration waveform. Specifically, the vibration period T of the vibration waveform is 1 / f, where f is the vibration frequency of the vibration waveform. The least common multiple of the target vibration period is compared with the vibration duration of the conflict area. If the target vibration period is less than or equal to the vibration duration of the conflict area, it is determined that the periodicity of the n vibration waveforms is relatively consistent and there will be no continuous mutual weakening. The n vibration waveforms can be superimposed to generate the target vibration waveform.
[0077] It should also be noted that, in the embodiments of this application, when the duration corresponding to the least common multiple of the vibration periods of the n vibration waveforms is less than or equal to the vibration duration of the conflict region, it can be determined that the vibration periods of the n vibration waveforms are relatively close. Therefore, the vibration frequency of the vibration waveforms does not need to be adjusted, and the original vibration frequency can be directly determined as the target vibration frequency.
[0078] In some embodiments, when the duration corresponding to the least common multiple of the vibration period is greater than the vibration duration of the conflict region, adjusting the vibration frequency of at least one of the n vibration waveforms may include:
[0079] A preset function is determined, using the vibration frequencies corresponding to the n vibration waveforms as variables;
[0080] Based on the preset function, the vibration frequency of at least one of the n vibration waveforms is adjusted until the duration corresponding to the least common multiple of the adjusted target vibration period is less than or equal to the vibration duration of the conflict region.
[0081] It should be noted that, in the embodiments of this application, when the duration corresponding to the least common multiple of the vibration periods of the n vibration waveforms is greater than the vibration duration of the conflict area, it indicates that the vibration periods of the n vibration waveforms differ significantly, and it is necessary to adjust the vibration frequency of at least one of the n vibration waveforms. Specifically, the overall frequency of the vibration waveform can be adjusted. When the vibration waveform is a variable frequency vibration, the vibration frequency of the vibration waveform can be adjusted locally, so that the duration corresponding to the least common multiple of the vibration periods of the n vibration waveforms is less than or equal to the vibration duration of the conflict area, and the adjusted vibration frequency is determined as the target vibration frequency.
[0082] It should be noted that, in the embodiments of this application, the vibration frequency of at least one of the n vibration waveforms can be adjusted using a preset function that takes the vibration frequencies corresponding to the n vibration waveforms as variables. Specifically, taking the adjustment of two vibration waveforms as an example, (f1′,f2′) = function(f1,f2) can be used to adjust the original vibration frequencies f1 and f2 to obtain the adjusted vibration frequencies f1′,f2′. If the vibration period corresponding to the adjusted vibration frequencies f1′,f2′ satisfies that the least common multiple is less than or equal to the vibration duration of the conflict area, the adjusted vibration frequency is determined as the target vibration frequency. Furthermore, taking the adjustment of multiple vibration waveforms as an example, (f1′,f2′…f n ′)=function(f1,f2…f n For the original vibration frequencies f1, f2…f nAdjustments were made to obtain the adjusted vibration frequencies f1′, f2′…f n The adjusted vibration frequencies are f1′, f2′…f′. n If the vibration period corresponding to ′ satisfies that the least common multiple is less than or equal to the vibration duration of the conflict area, the adjusted vibration frequency is determined as the target vibration frequency.
[0083] In this way, by adjusting the vibration frequency of at least one of the n vibration waveforms, and ensuring that the vibration period satisfies the condition that the least common multiple is less than or equal to the vibration duration of the conflict region, the target vibration frequency corresponding to the n vibration waveforms can be obtained.
[0084] S103: Based on the target vibration frequency, n vibration waveforms are superimposed to generate the target vibration waveform.
[0085] It should be noted that, in the embodiments of this application, while maintaining the target vibration frequency, n vibration waveforms are superimposed and merged to obtain the final target vibration waveform. Specifically, the peaks and troughs of the n vibration waveforms can be superimposed, which can maximize the vibration amount of the target vibration waveform and obtain a clearer vibration effect.
[0086] In some embodiments, the step of superimposing the n vibration waveforms based on the target vibration frequency to obtain the target vibration waveform may further include:
[0087] While keeping the target vibration frequency constant, the vibration magnitude of the n vibration waveforms at each point is summed to obtain the target vibration waveform.
[0088] It should be noted that, in the embodiments of this application, the vibration quantities of n vibration waveforms can be directly summed to obtain the target vibration waveform. Specifically, the vibration quantity of each point on the vibration waveform can be summed to obtain the target vibration waveform.
[0089] In some embodiments, the step of superimposing the n vibration waveforms based on the target vibration frequency to obtain the target vibration waveform may include:
[0090] While keeping the target vibration frequency constant, determine the target weights corresponding to the n vibration waveforms;
[0091] Based on the target weight, the vibration magnitude of the n vibration waveforms at each point is weighted and summed to obtain the target vibration waveform.
[0092] It should be noted that, in the process of determining the target weight, the preset weight of the vibration waveform can be determined according to the expected vibration effect to be obtained, or the preset weight of the vibration waveform can be determined according to the importance ranking, etc. Finally, the preset weight is determined as the target weight, and the n vibration waveforms are superimposed and merged. Specifically, the vibration amount of each point on the vibration waveform can be weighted and summed to obtain the target vibration waveform.
[0093] In some embodiments, determining the target weights corresponding to the n vibration waveforms may include:
[0094] Determine the target vibration waveform corresponding to the target vibration effect;
[0095] Based on the target vibration waveform, the importance of the n vibration waveforms is ranked, and the target weights corresponding to the n vibration waveforms are determined in turn.
[0096] It should be noted that, in the embodiments of this application, when determining the target weight, the target weight corresponding to different vibration waveforms can be adjusted according to the target vibration effect, and the target weight of different vibration waveforms can also be determined according to user preferences, etc., without any limitation.
[0097] This application provides a waveform processing method that obtains the vibration frequencies corresponding to n conflicting vibration waveforms, where n is an integer greater than or equal to 2; adjusts the vibration frequency of at least one of the n vibration waveforms to obtain a target vibration frequency corresponding to the n vibration waveforms, and the target vibration frequency satisfies a first preset condition; and superimposes the n vibration waveforms based on the target vibration frequency to generate a target vibration waveform. In this way, by adjusting the frequency of the vibration waveforms, the vibration waveforms can be better superimposed at the target vibration frequency, which not only improves the vibration sensing superposition effect but also enables rich mixed vibration sensing.
[0098] In another embodiment of this application, based on the waveform processing method described in the foregoing embodiments, see [link to previous document]. Figure 2 This illustrates a detailed flowchart of a waveform processing method provided in an embodiment of this application. Figure 2 As shown, the method may include:
[0099] S201: Obtain the vibration frequency of the mixed vibration waveform and calculate the vibration period time.
[0100] S202: Fine-tune the vibration frequency so that the least common multiple of the vibration period is less than the vibration duration of the conflict zone.
[0101] S203: Adjust the weights of the vibration waveform according to requirements to achieve the desired vibration effect of the mixed vibration.
[0102] S204: Processing complete.
[0103] Specifically, in this embodiment of the application, mixed vibration information is obtained, and the vibration period time of the mixed vibration waveform is processed based on this information so that the adjusted period time of the mixed vibration waveform has the least common multiple period time during the vibration time of the conflict area. Furthermore, weights are assigned to the vibration waveform to achieve the expected vibration effect, including the effect of achieving the maximum vibration amount of the mixed vibration waveform.
[0104] This application embodiment obtains the vibration frequencies of the mixed vibration waveforms and fine-tunes them to ensure that the vibration period times have a least common multiple of time, and this least common multiple time is less than the vibration duration of the conflict region, thereby achieving the expected vibration effect. The vibration period times t1, t2, ..., tn are obtained based on the vibration frequencies f1, f2, ..., fn of N mixed vibration waveforms, and the vibration frequencies are fine-tuned to ensure that the least common multiple time t of the vibration period times is achieved. lcm Vibration duration t in the conflict zone total This allows the mixed vibration of N vibration waveforms to achieve the maximum vibration amount within the vibration duration of the conflict zone, or to assign different weights to individual vibrations and superimpose them, so that the final mixed vibration waveform has a richer vibration effect.
[0105] For example, consider the hybrid vibration treatment method with N=2:
[0106] Obtain the vibration frequencies f1 and f2 of the two vibration waveforms, as well as the vibration duration t of the conflict region. total Adjust the vibration frequencies of the two vibration waveforms to have a least common multiple, that is, make the vibration period time a least common multiple t. lcm At this point, the maximum vibration effect of the two vibration waveforms can be obtained.
[0107] Ift lcm >t total ;
[0108] Then:f1′,f2′)=function(f1,f2);
[0109] t l ′ cm <t total .
[0110] Where f1' and f2' are the fine-tuned vibration frequencies, and t lcm ' is the least common multiple of the vibration period time after fine-tuning the vibration frequency.
[0111] For example, a hybrid vibration treatment method with N=2 is used.
[0112] Obtain the vibration frequencies f1 and f2 of the two vibration waveforms, as well as the vibration duration t of the conflict region. total The vibration period times t1 and t2 are obtained through the vibration frequency. At the same time, the preset weights A1 and A2 of the two vibration waveforms are calculated according to the desired vibration effect. By adjusting the vibration frequency of the two vibration waveforms and assigning weights to the two vibration waveforms, the mixed vibration waveform achieves the desired vibration effect.
[0113] final wave =A1×wave1+A2×wave2.
[0114] Where wave1 and wave2 are the waveforms after frequency adjustment, and A1 and A2 are the waveform weights.
[0115] See Figure 3 It shows a waveform diagram of a vibration waveform mixture provided by related technologies, such as... Figure 3 The mixed waveform shown exhibits unstable vibration and lacks periodicity, resulting in poor vibration performance. In some specific embodiments, see [reference needed]. Figure 4 The illustration shows a waveform diagram of a vibration waveform mixture provided in an embodiment of this application. By adjusting the frequencies of the two waveforms, the period of the adjusted waveform has a least common multiple, and the duration corresponding to the least common multiple is less than or equal to the vibration duration of the conflict area. The adjusted waveforms are then superimposed and merged to obtain a mixed waveform with a relatively stable vibration effect and a certain periodicity, achieving the expected vibration effect.
[0116] This application provides a waveform processing method. Based on the above embodiments, the specific implementation of the aforementioned embodiments is described in detail. It can be seen that, according to the technical solution of the aforementioned embodiments, this technical solution proposes to obtain mixed vibration information, process the vibration period time of the mixed vibration waveform based on this information, so that the adjusted mixed vibration waveform period time has the least common multiple period time within the vibration duration of the conflict region, and further assign weights to the vibration waveform to achieve the expected vibration effect, including achieving the effect of the maximum vibration amount of the mixed vibration waveform, etc.
