Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Specifically, as shown in FIG. 1, in one embodiment, a method for suppressing vibration of an electronic device housing is provided. The execution of the method for suppressing the vibration of the housing of an electronic device may be based on an electronic device such as a smart phone, and the electronic device is provided with a speaker to receive audio signals for sound playback.

It should be noted that the implementation of the above-mentioned method for suppressing the vibration of the electronic device casing is mainly based on the case of external sound reproduction through electronic devices such as smart phones, that is, only in the case of audio playback and external sound reproduction The above-mentioned method of suppressing the vibration of the housing of the electronic device is executed.

Please refer to FIG. 1. The above-mentioned method for suppressing the vibration of the electronic device housing includes steps S102-S108 as shown in FIG. 1.

Step S102: Acquire an audio signal to be processed.

The audio signal to be processed is the audio signal that needs to be played, for example, the audio signal to be played generated by a certain music playback software.

Step S104: Detect the target acceleration data by the acceleration sensor, and determine the target shell vibration level data of the shell according to the target acceleration data.

In this step, the acceleration sensor can be used to detect whether the housing of the electronic device has case vibration, which is specifically determined by acceleration data detected by the acceleration sensor.

Wherein, the acceleration sensor includes one or more acceleration sensors arranged inside the electronic device and/or on the housing of the electronic device for detecting corresponding acceleration data, that is, target acceleration data. Among them, it includes acquiring first acceleration data corresponding to different positions of the housing through a plurality of acceleration sensors arranged at different positions on the housing; through the one or more acceleration sensors arranged inside the electronic device The sensor acquires the second acceleration data inside the electronic device.

It should be noted that one or more acceleration sensors may be provided inside the electronic device to detect the case vibration inside the electronic device. One or more acceleration sensors can also be provided on the housing of the electronic device (the location can be determined according to the user's holding state of the electronic device) to detect the actual vibration of the housing, thereby improving the accuracy of the housing vibration detection.

In a specific embodiment, the description of the shell vibration level can be determined by using the first acceleration data, or by using only the second acceleration data, or by combining the first acceleration data and the second acceleration data.

After the acceleration data is detected, the detected shell vibration can be evaluated based on the acceleration data, that is, the target shell vibration level data. In specific implementation, according to the preset shell vibration level calculation model, the corresponding target shell vibration level data is calculated based on the target acceleration data. Among them, the target shell vibration level data may be a shell vibration level curve.

Specifically, the shell vibration level corresponding to the target acceleration data is determined according to the preset acceleration measurement value-the shell vibration level evaluation model, which is the target shell vibration level data. Among them, the preset acceleration measurement value-shell vibration level evaluation model is a model corresponding to the mapping relationship between the acceleration measurement value and the shell vibration level, that is to say, according to this model, after the target acceleration data is measured, it can be The model determines the corresponding shell vibration level data. Among them, the preset acceleration measurement value-shell vibration level evaluation model is the corresponding relationship between the acceleration measurement value and the shell vibration level constructed in advance for the test of the electronic device, for example, is the frequency between the shell vibration level and the acceleration measurement value. Domain ratio relationship.

Further, when calculating the target shell vibration level data, the corresponding shell vibration level data is calculated according to the acceleration data measured by different acceleration values, and then the final target shell vibration level data is determined. Specifically, the first shell vibration level data corresponding to the first acceleration data is calculated, and the second shell vibration level data corresponding to the second acceleration data is calculated; according to the first shell vibration level data and the first The second shell vibration level data is used to calculate the target shell vibration level data.

It should be noted that, in this embodiment, in order to accurately evaluate the shell vibration level, the acceleration sensor is preferably a plurality of acceleration sensors arranged on the housing of the electronic device at different positions, and the housing vibration at each position of the housing Carrying out the test can more comprehensively evaluate the shell vibration level.

In one embodiment, when the target acceleration data includes the first acceleration data and the second acceleration data, in the process of determining the shell vibration level, it is necessary to comprehensively consider the contribution between the two to the real shell vibration level.

Specifically, in the case where the first shell vibration level data and the second shell vibration level data are obtained by calculation, the corresponding target shell vibration level data is calculated according to a preset weighted average algorithm.

In another embodiment, when multiple acceleration sensors are provided on the housing of the electronic device, the first acceleration data includes acceleration data corresponding to each acceleration sensor. In this case, in the process of calculating the first acceleration data or the corresponding first shell vibration level data, according to the calculation formula (for example, the preset weighted average algorithm) constructed in advance according to the position set by the acceleration sensor, the corresponding The first acceleration data or the first shell vibration level data. That is to say, the case vibration detected by the acceleration sensors at different positions on the shell is comprehensively considered, and the overall case vibration can be evaluated more accurately, and the effectiveness of subsequent suppression of the case vibration can be improved.

In this embodiment, the entire electronic device has been tested in advance to obtain a solution for how to suppress the shell vibration. Specifically, after the audio signal to be processed is determined, the estimated shell vibration level data corresponding to the audio signal to be processed can be calculated according to the preset audio signal-shell vibration level evaluation model, where the estimated shell vibration level The data is a description of the shell vibration that will be generated if the audio signal to be processed is input to the speaker of the electronic device, which is predicted by the audio signal-shell vibration level evaluation model. It should be noted that the estimated shell vibration level data is also part of the target shell vibration level data, and the estimated shell vibration level data also needs to be considered in the subsequent calculation of the target shell vibration suppression parameters and the suppression process.

Among them, the audio signal-shell vibration level evaluation model is a transfer function between the audio signal and the shell vibration level, which is a model constructed by pre-testing the electronic device to determine the correspondence between the audio signal and the shell vibration level.

Step S106: Calculate the target shell vibration suppression parameter according to the target shell vibration level data.

After determining the target shell vibration level data that identifies the current shell vibration situation, the corresponding target shell vibration suppression parameters can be calculated, where the target shell vibration suppression parameters are the parameters that need to be suppressed, for example, it can be processed The equalization parameter of the audio signal for equalization processing, or the control parameter of the audio signal to be processed.

In this embodiment, before calculating the target shell vibration suppression parameter, it is necessary to determine a preset shell vibration level threshold or a control target of shell vibration suppression. Among them, the shell vibration level threshold and the control target of shell vibration suppression identify the maximum allowable shell vibration level. According to the shell vibration level threshold, it can be determined that the shell vibration needs to be controlled within a certain range to determine the corresponding target shell vibration suppression parameters .

In specific implementation, it is determined whether the target shell vibration level data meets the preset shell vibration level threshold; then, in the case that the target shell vibration level data meets the preset shell vibration level threshold, the to-be-processed audio The signal is used as the target audio signal and output to the speaker of the electronic device, that is, it is not necessary to suppress the shell vibration, and the sound can be directly output; when the target shell vibration level data does not meet the preset shell vibration level threshold In this case, the target shell vibration suppression parameter is calculated according to the target shell vibration level data and the preset shell vibration level threshold, that is, it is necessary to calculate the preset shell vibration suppression control target according to the shell vibration level threshold. Vibration suppression corresponds to the target shell vibration suppression parameter.

Different users have different tolerance to shell vibration, and considering that shell vibration suppression may also have a certain impact on audio to a certain extent, therefore, different shell vibration level thresholds can be set according to different users and different application scenarios.

In specific implementation, the user can select and set application scenarios, and different application scenarios correspond to different shell vibration level thresholds, and also correspond to different shell vibration suppression effects. For example, application scenarios may include optimal sound quality mode, balanced mode, no vibration mode, etc. The corresponding shell vibration suppression effect is low shell vibration suppression level, medium shell vibration suppression level, high shell vibration suppression level, etc. Users can choose different shell vibration suppression effects based on subjective experience. In the process of execution, the current application scene parameters of the electronic device need to be determined; then the corresponding shell vibration level threshold is determined according to the current scene parameters as the preset shell vibration level threshold, and the preset shell vibration level threshold is determined according to the determined preset shell vibration level threshold. Determine to what extent the shell vibration needs to be suppressed.

Step S108: Perform equalization processing on the to-be-processed audio signal according to the target shell vibration suppression parameter, obtain the equalized target audio signal, and output the target audio signal to the speaker of the electronic device.

After the target shell vibration suppression parameter is determined, the audio signal to be processed can be equalized according to the target shell vibration suppression parameter, that is, the equalized signal corresponding to the target shell vibration suppression parameter is applied to the audio signal to be processed, so as to obtain the equalization process. The target audio signal. Then the target audio signal is output to the speaker of the electronic device, and then the sound is externally amplified through the speaker. At this time, the shell vibration of the electronic device is controlled within a certain range, which is effectively suppressed.

Through the above steps S102-S108, according to the input audio signal and the shell vibration level determined by the acceleration sensor detection value, calculate the target shell vibration suppression parameter corresponding to the shell vibration suppression, and then process the audio signal according to the target shell vibration suppression parameter Then input the speaker to effectively suppress the shell vibration.

Further, in the above method for suppressing the vibration of the electronic device housing, the possible housing vibration level data is predicted through the audio signal to be processed in advance, and then the actual housing vibration is detected by the acceleration sensor when the sound is output. Detection: Determine whether the predicted shell vibration level data is accurate according to the actual detection situation, and then determine the shell vibration suppression parameters that need to be corrected based on the predicted shell vibration level data and the detected shell vibration level data, and then process the audio signal to be processed , In order to achieve the effect of shell vibration suppression.

Further, in this embodiment, in order to predict the shell vibration as much as possible, as mentioned above, the shell vibration situation can be predicted based on the audio signal, so that the corresponding shell vibration suppression parameters can be calculated, so that the sound Before the external amplifier, the shell vibration that may exist in the audio signal is suppressed according to the shell vibration suppression parameter. Specifically, the initial shell vibration suppression parameter is obtained. The initial shell vibration suppression parameter is the shell vibration suppression parameter determined according to the shell vibration level data predicted by the audio signal. Then, the audio signal to be processed is preprocessed according to the initial shell vibration suppression parameter and then input The speaker of the electronic device reduces the shell vibration and improves the efficiency of the shell vibration suppression.
