Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the defect of poor consistency of vibration sense when vibration sense feedback is performed on different electronic devices for the same audio frequency in the related art, a first embodiment of the present application provides a vibration control method, for example, fig. 1 is a basic flowchart of the vibration control method provided in this embodiment, where the vibration control method includes the following steps:
Specifically, the waveform library of this embodiment includes a mapping relationship between the vibration waveform and the driving waveform, and the vibration waveforms included in the waveform libraries corresponding to different motor configuration attributes are consistent. In practical application, the motor includes a linear motor, a rotor motor and the like mounted on the electronic device, the electronic device is not limited to a mobile phone, and may further include a handle or an intelligent wearable device and other devices having a vibration function, the motor configuration attribute may include a motor model, a motor mounting position and the like, and at present, the motor configuration attributes of different series of electronic devices of the same manufacturer or different types of electronic devices of the same series are usually different. In addition, the vibration control scene of the embodiment not only includes the audio vibration following the incoming call, the notification of charging, the alarm clock and the like, but also includes the audio vibration following the game, the video and the like.
It should be understood that the vibration waveform is a waveform of a vibration signal transmitted to the outside when the motor vibrates, and the driving waveform is a waveform of an electric signal that the driving IC of the electronic device drives the motor to vibrate. In the present embodiment, the vibration waveforms required to be output for the same audio frequency are consistent, and the driving waveforms corresponding to the motors with different configuration attributes are different under each vibration waveform. In this embodiment, taking the example that the motor configuration attribute includes a motor configuration attribute a and a motor configuration attribute B, and the vibration waveform type includes a vibration waveform a, a vibration waveform B, and a vibration waveform C, the waveform library corresponding to the motor configuration attribute a includes mapping relationships between the vibration waveform a, the vibration waveform B, and the vibration waveform C and the driving waveforms 1, 2, and 3, and the waveform library corresponding to the motor configuration attribute B includes mapping relationships between the vibration waveform a, the vibration waveform B, and the vibration waveform C and the driving waveforms 4, 5, and 6, that is, for motors with different configuration attributes, the driving waveforms corresponding to the same vibration waveform are different.
It should also be noted that, in this embodiment, on the premise that the output vibration waveforms are kept consistent, waveform libraries corresponding to different motors are established through big data of waveform debugging in the early stage, and then the accuracy of the waveform libraries is further optimized by continuously fitting the correlation between the driving waveforms and the existing vibration waveforms through machine learning.
And 102, searching a corresponding target driving waveform in a waveform library based on the target vibration waveform.
Specifically, in this embodiment, in consideration of the fact that the types of audio required to be output by the electronic device in practical application are different, in order to ensure the vibration interaction experience of the user, different vibration effects are usually set for different audio types, for example, a vibration waveform a is set for an incoming call alert tone, a vibration waveform B is set for a charging alert tone, and the like, so as to meet the diversified and personalized vibration interaction requirements of the user. In this embodiment, the vibration waveform is used as the input factor for searching the waveform library, and the corresponding driving waveform can be output.
In some embodiments of the present embodiment, obtaining a target vibration waveform corresponding to audio to be played includes: carrying out segmentation processing on the audio to be played and acquiring audio characteristic parameters of each audio clip; and respectively configuring the target vibration waveform corresponding to each audio frequency segment according to each audio frequency characteristic parameter. Correspondingly, based on the target vibration waveform, searching the corresponding target driving waveform in the waveform library, including: searching corresponding driving waveforms in a waveform library based on the target vibration waveforms respectively; and synthesizing all searched driving waveforms according to the playing sequence of the audio clips to obtain the target driving waveform.
Specifically, in practical application, the corresponding vibration waveforms may be pre-associated with different audio frequencies, and then in an audio frequency vibration scene, the preset corresponding relationship may be directly queried according to the audio frequency to be played to obtain the target vibration waveform. However, in consideration of the difficulty in pre-associating vibration waveforms of all types of audio in practical applications and the poor accuracy of configuring the vibration waveforms corresponding to the audio as a whole, the present embodiment performs segmentation processing on the audio to be played, extracts audio feature parameters of each audio segment, and configures the vibration waveforms of each audio segment correspondingly based on the audio features of each audio segment, so that on one hand, vibration waveforms with high adaptability can be configured effectively for the audio not considered in advance, and on the other hand, the vibration waveforms are configured by using the audio segments as the minimum unit, and the accuracy of the configured vibration waveforms can be improved.
In addition, in this embodiment, when the driving waveform of the audio to be played is obtained, the driving waveform of each audio segment is correspondingly obtained according to the vibration waveform of each audio segment, and then the driving waveforms of each audio segment are synthesized according to the playing sequence of the audio segments, so that the driving waveform of the whole audio to be played can be obtained. For example, the audio to be played includes audio segments 1, 2, and 3 that are played sequentially, the driving waveforms corresponding to the three audio segments are driving waveforms A, B, C, and the synthesized target driving waveform is driving waveform (a + B + C). It should be understood that, in practical applications, the specific representation form of the driving waveform may be a driving format file, and the sequence of the sub-driving format files corresponding to each audio segment in the synthesized driving format file determines the sequence of the sub-driving format files during audio playing.
Further, in some embodiments of this embodiment, configuring a target vibration waveform corresponding to each audio segment according to each audio feature parameter includes: determining corresponding waveform vibration duration, waveform vibration amplitude and waveform vibration frequency according to the audio duration, the audio amplitude and the audio frequency of the audio clip; and respectively configuring target vibration waveforms corresponding to the audio frequency segments on the basis of the waveform vibration duration, the waveform vibration amplitude and the waveform vibration frequency.
Specifically, the audio characteristic parameters of the embodiment include: audio duration, audio amplitude, audio frequency. In this embodiment, the waveform characteristics of the vibration waveform are adaptively determined according to the audio characteristics, so that the adaptability of the vibration waveform and the waveform of the audio signal can be effectively ensured, and the adaptability is specifically embodied that the speed, intensity and duration of the vibration sense of the audio along with vibration are adapted to the speed, tone height and playing duration of the rhythm of the audio, so that the correlation between the vibration sense and music can be improved, and vibration sense interactive experience with higher recognition degree and interestingness is provided for a user.
And 103, calling a target driving waveform to control the motor to vibrate when the audio to be played is played.
Specifically, in the embodiment, the motor of the electronic device is synchronously controlled to vibrate while the audio is played, so as to realize the audio vibration. In practical application, drive waveforms are respectively and adaptively configured according to different motor configuration attributes aiming at electronic devices of different models produced by the same electronic device manufacturer, so that vibration waveforms output by the electronic devices with different motor configuration conditions aiming at the same audio frequency are consistent, the consistency of vibration senses output by the electronic devices (such as iterative products) aiming at the same audio frequency can be effectively ensured, the vibration sense interaction experience of a user is improved, and the vibration sense identification degree of the electronic device brand is ensured.
As shown in fig. 2, which is a schematic flow chart of the method for searching for a driving waveform provided in this embodiment, in some embodiments of this embodiment, the flow of searching for a corresponding target driving waveform in a waveform library based on a target vibration waveform specifically includes the following steps:
and step 204, searching a target driving waveform in a waveform library through the vibration waveform of the history playing audio.
Specifically, in practical application, since it is difficult to fully cover the driving waveforms corresponding to all the vibration waveforms in the waveform library, there may be no query result for a specific vibration waveform, for example, if the current audio to be played is strange audio, the vibration waveform corresponding to the current audio to be played is not considered in advance, and for this situation, this embodiment may acquire an audio playing scene corresponding to the audio to be played, then acquire the history playing audio in the same playing scene, then query the waveform library based on the vibration waveform of the history playing audio, and determine the driving waveform corresponding to the history playing audio as the driving waveform of the current audio to be played, thereby avoiding the failure of the audio vibration following function.
For example, in an incoming call ringing scene, a user sets a certain system ring tone for an incoming call prompt in a historical usage scene, and a corresponding relationship between a vibration waveform and a driving waveform of the system ring tone is preconfigured by an electronic device manufacturer, and if the user changes the ring tone of the incoming call prompt into other third-party ring tones in a subsequent usage process, the corresponding driving waveform cannot be found in a preconfigured waveform library, and because the third-party ring tone and the system ring tone are both applied to the incoming call ringing scene, considering that the user generally has the same audio vibration following requirement in the same scene, the driving waveform of the previously used system ring tone can be directly determined as the driving waveform of the current third-party ring tone.
As shown in fig. 3, which is a schematic flow chart of another driving waveform searching method provided in this embodiment, in some embodiments of this embodiment, the flow of searching for a corresponding target driving waveform in the waveform library based on the target vibration waveform specifically includes the following steps:
Specifically, in another implementation, if the waveform library does not provide the driving waveform of the target vibration waveform, a vibration waveform with a waveform approximate to the target vibration waveform may be obtained from the waveform library based on the waveform characteristics, and then the driving waveform corresponding to the vibration waveform in the waveform library is determined as the driving waveform corresponding to the target vibration waveform, so that a vibration following experience with a correlation with music as high as possible may be provided for strange audio with which the driving waveform is not configured in advance.
As shown in fig. 4, which is a schematic flow chart of the audio vibration following method provided in this embodiment, in some embodiments of this embodiment, the flow of calling the target driving waveform to control the motor to vibrate when the audio to be played is played specifically includes the following steps:
and step 404, controlling the motor to vibrate based on the adjusted target driving waveform when the audio to be played is played.
In particular, in practical applications, the specific scenes of the electronic device used by the user are different, the usage scenes may include a motion usage scene, a still usage scene, and the like, while waveform library configuration is typically done, the drive waveforms are typically configured for standard usage scenarios, on the basis that the vibration intensity output according to the target driving waveform does not meet the actual requirement of the user when the difference between the actual use scene and the standard use scene is large, the embodiment correspondingly determines the vibration amplitude adjustment amount of the target driving waveform according to the difference between the current use scene and the standard use scene, then, the target driving waveform after the vibration amplitude is adjusted to realize the ringing, for example, in a motion use scene, the perception capability of the user to the vibration is relatively weak, the waveform vibration amplitude of the driving waveform can be enhanced to allow the user to normally perceive the audio as vibrating with a relatively strong vibration intensity.
In other embodiments of this embodiment, when playing an audio to be played, the process of calling the target driving waveform to control the vibration of the motor specifically includes the following steps: when the audio to be played is played, generating a vibration control instruction based on the target driving waveform; and sending a vibration control instruction to the associated equipment based on the communication connection with the associated equipment so as to trigger the associated equipment to control the motor to vibrate according to the target driving waveform.
Specifically, in this embodiment, the electronic device is taken as a mobile phone, and the associated device may be a wearable device, such as a smart watch and smart glasses. In practical applications, a typical application of the audio vibration with following is to provide a reminder to a user, and the electronic device used by the user may not be carried by the user, and then the vibration sense cannot be effectively conveyed to the user, so that, in the embodiment, considering that the wearable device bound to the electronic device is generally a device carried by the user, when the electronic device plays audio, a vibration control instruction carrying a target driving waveform is sent to the associated device to control the associated device to vibrate with following according to the audio played by the electronic device, and even if the user does not perceive the audio played by the electronic device because of being far away from the electronic device, the user can be reminded by the vibration sense output by the associated device.
Based on the technical scheme of the embodiment of the application, a target vibration waveform corresponding to the audio to be played is obtained, and a waveform library corresponding to the configuration attributes of the motor is obtained, wherein the waveform library comprises a mapping relation between the vibration waveform and the driving waveform, and the vibration waveforms in the waveform libraries corresponding to different configuration attributes of the motor are consistent; searching a corresponding target driving waveform in a waveform library based on the target vibration waveform; and when the audio to be played is played, calling the target driving waveform to control the motor to vibrate. Through the implementation of the scheme, the driving waveforms are respectively adaptively configured according to different motor configuration attributes, so that the vibration waveforms output by the electronic devices with different motor configuration conditions are consistent for the same audio frequency, the consistency of the vibration sense output by the electronic devices for the same audio frequency can be effectively ensured, and the vibration sense interaction experience of users is improved.
The method in fig. 5 is a refined vibration control method provided in a second embodiment of the present application, and the vibration control method includes:
and 501, performing segmentation processing on the audio to be played, and acquiring audio characteristic parameters of each audio clip.
Specifically, in this embodiment, the audio to be played may be an incoming call prompt tone, a charging prompt tone, and the like, and the audio characteristic parameter may include: audio duration, audio amplitude, audio frequency, etc.
And 502, configuring a target vibration waveform corresponding to each audio segment according to each audio characteristic parameter.
Specifically, in the present embodiment, the vibration waveforms of the audio segments are configured correspondingly based on the audio features of the audio segments, that is, the vibration waveforms are configured by using the audio segments as the minimum unit, so that the accuracy of the configured vibration waveforms can be improved, and for the difficulty in pre-associating the corresponding vibration waveforms for all complete audios in practical application, only limited characteristic vibration waveforms can be prepared in advance, and then flexible selection and synthesis are performed according to the audio features of the specific audio to be played, so that the workload of configuring the vibration waveforms in association with the audio can be effectively reduced.
Specifically, the waveform library of this embodiment includes a mapping relationship between the vibration waveform and the driving waveform, and the vibration waveforms included in the waveform libraries corresponding to different motor configuration attributes are consistent.
And step 504, synthesizing all searched driving waveforms according to the playing sequence of the audio clips to obtain the target driving waveform.
Specifically, in this embodiment, when the driving waveform of the audio to be played is obtained, the driving waveform of each audio segment is correspondingly obtained according to the vibration waveform of each audio segment, and then the driving waveforms of each audio segment are synthesized according to the playing sequence of the audio segments, so that the driving waveform of the whole audio to be played can be obtained.
And 505, comparing the current use scene information of the electronic device with the standard use scene information.
Specifically, in practical applications, specific scenes of the electronic device used by a user are different, the usage scenes may include a motion usage scene, a static usage scene, and the like, and when the waveform library is configured, the driving waveform is configured for a standard usage scene, and when the difference between the actual usage scene and the standard usage scene is large, the problem that the vibration intensity output according to the target driving waveform does not meet the actual needs of the user may exist.
And step 506, when the comparison is inconsistent, determining a corresponding waveform vibration amplitude adjustment amount based on the difference characterization parameters of the current use scene information and the standard use scene information.
And 507, adjusting the waveform vibration amplitude of the target driving waveform based on the waveform vibration amplitude adjustment amount.
And step 508, controlling the motor to vibrate based on the adjusted target driving waveform when the audio to be played is played.
Specifically, the present embodiment correspondingly determines the vibration amplitude adjustment amount of the target driving waveform according to the difference between the current usage scenario and the standard usage scenario, and then implements ringing by adjusting the target driving waveform after the vibration amplitude, so as to provide the vibration feedback suitable for the usage scenario of the electronic device to the user.
It should be understood that, the size of the serial number of each step in this embodiment does not mean the execution sequence of the step, and the execution sequence of each step should be determined by its function and inherent logic, and should not be limited uniquely to the implementation process of the embodiment of the present application.
According to the vibration control method disclosed by the embodiment of the application, the driving waveforms are respectively configured adaptively according to different motor configuration attributes, so that the vibration waveforms output by electronic devices with different motor configuration conditions for the same audio frequency are consistent, the consistency of vibration senses output on different electronic devices for the same audio frequency can be effectively ensured, and the vibration sense interaction experience of a user is improved; in addition, the vibration intensity of the audio along with vibration is adjusted according to the use scene adaptability of the electronic device, so that vibration feedback adaptive to the use scene of the electronic device is provided for a user.
