Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In this embodiment, in order to suppress the shell vibration of the electronic device such as the smart phone in the sound playing process, a method for suppressing the shell vibration of the electronic device is provided, which can effectively reduce the shell vibration caused by sound playing without changing the speaker structure and the mobile phone structure, and improve the user experience.
Specifically, as shown in FIG. 1, in one embodiment, a method of damping vibrations of an electronic device housing is provided. The method for suppressing the vibration of the electronic device housing may be performed by an electronic device such as a smart phone, and a speaker is provided in the electronic device to receive an audio signal for playing sound.
The method for suppressing the vibration of the electronic device case is mainly based on the case of performing sound reproduction by an electronic device such as a smart phone, that is, the method for suppressing the vibration of the electronic device case is performed only when audio playback is performed and sound reproduction is performed.
Referring to fig. 1, the method for suppressing vibration of the electronic device housing includes steps S102 to S108 shown in fig. 1:
step S102: an audio signal to be processed is acquired.
The audio signal to be processed is an audio signal to be played, for example, an audio signal to be played generated by a certain music playing software.
Step S104: and detecting target acceleration data through an acceleration sensor, and determining target shell vibration level data of the shell according to the target acceleration data.
In this step, whether or not a housing vibration occurs in the housing of the electronic device can be detected by the acceleration sensor, specifically, determined by the acceleration data detected by the acceleration sensor.
The acceleration sensor comprises one or more acceleration sensors arranged in the electronic equipment and/or on the electronic equipment shell, and is used for detecting corresponding acceleration data, namely target acceleration data. The method comprises the steps of respectively acquiring first acceleration data corresponding to different positions of the shell through a plurality of acceleration sensors arranged at different positions of the shell; and acquiring second acceleration data in the electronic equipment through the one or more acceleration sensors arranged in the electronic equipment.
It should be noted that, one or more acceleration sensors may be disposed inside the electronic device to detect a shell vibration condition inside the electronic device. One or more acceleration sensors (the setting position can be determined according to the holding state of the electronic equipment used by a user) can be arranged on the shell of the electronic equipment to detect the actual vibration condition of the shell, so that the accuracy of shell vibration detection is improved.
In a specific embodiment, the shell vibration level may be determined using the first acceleration data, the second acceleration data alone, or a combination of the first acceleration data and the second acceleration data.
After the acceleration data is detected, the detected shell vibration condition, i.e. the target shell vibration level data, can be evaluated according to the acceleration data. In specific implementation, according to a preset shell vibration level calculation model, corresponding target shell vibration level data is calculated based on target acceleration data. Wherein the target shell vibration level data may be a shell vibration level curve.
Specifically, according to a preset acceleration measurement value-shell vibration level evaluation model, determining a shell vibration level corresponding to target acceleration data, namely, target shell vibration level data. The preset acceleration measurement value-shell vibration level evaluation model is a model corresponding to the mapping relation between the acceleration measurement value and the shell vibration level, that is, after the target acceleration data is measured according to the model, the corresponding shell vibration level data can be determined according to the model. The preset acceleration measurement value-shell vibration level evaluation model is a corresponding relation between an acceleration measurement value and a shell vibration level, which is built by testing the electronic equipment in advance, for example, is a frequency domain ratio relation between the shell vibration level and the acceleration measurement value.
Further, when calculating the target shell vibration level data, corresponding shell vibration level data are calculated according to the acceleration data measured by different acceleration values, and then final target shell vibration level data are determined. Specifically, first shell vibration level data corresponding to the first acceleration data are calculated, and second shell vibration level data corresponding to the second acceleration data are calculated; and calculating the target shell vibration level data according to the first shell vibration level data and the second shell vibration level data.
In this embodiment, in order to accurately evaluate the shell vibration level, the acceleration sensor is preferably a plurality of acceleration sensors disposed at different positions on the housing of the electronic device, and detects the shell vibration at each position of the housing, so that the shell vibration level can be evaluated more comprehensively.
In one embodiment, where the target acceleration data includes first acceleration data and second acceleration data, the contribution to the true shell vibration level between the two needs to be comprehensively considered in determining the shell vibration level.
Specifically, under the condition that the first shell vibration level data and the second shell vibration level data are obtained through calculation, corresponding target shell vibration level data are calculated according to a preset weighted average algorithm.
In another embodiment, in a case where a plurality of acceleration sensors are provided on the electronic device case, the first acceleration data includes acceleration data respectively corresponding to each of the acceleration sensors. In this case, in calculating the first acceleration data or the corresponding first shell vibration level data, the corresponding first acceleration data or first shell vibration level data is calculated according to a calculation formula (for example, a preset weighted average algorithm) constructed in advance according to the position set by the acceleration sensor. That is, the shell vibration conditions detected by the acceleration sensors at different positions on the shell are comprehensively considered, the whole shell vibration conditions can be more accurately evaluated, and the effectiveness of the follow-up shell vibration inhibition is improved.
In this embodiment, tests have been performed in advance for the whole electronic apparatus, and a scheme of how the shell vibration should be suppressed has been obtained. Specifically, after the audio signal to be processed is determined, estimated shell vibration level data corresponding to the audio signal to be processed can be calculated according to a preset audio signal-shell vibration level evaluation model, wherein the estimated shell vibration level data is a description of shell vibration conditions, which are predicted according to the audio signal-shell vibration level evaluation model and generated if the audio signal to be processed is input into a loudspeaker of the electronic device. The estimated shell vibration level data is also a part of the target shell vibration level data, and the estimated shell vibration level data needs to be considered in the subsequent process of calculating the target shell vibration suppression parameters and performing suppression.
The audio signal-shell vibration level evaluation model is a transfer function between an audio signal and a shell vibration level, and is a model constructed by testing electronic equipment in advance to determine the corresponding relation between the audio signal and the shell vibration level.
Step S106: and calculating a target shell vibration suppression parameter according to the target shell vibration level data.
After determining the target shell vibration level data for identifying the current shell vibration condition, a corresponding target shell vibration suppression parameter can be calculated, wherein the target shell vibration suppression parameter is a parameter needing to suppress the shell vibration, and for example, the target shell vibration suppression parameter can be an equalization parameter for performing equalization processing on an audio signal to be processed or a control parameter of the audio signal to be processed.
In the present embodiment, a preset shell vibration level threshold or control target of shell vibration suppression needs to be determined before calculating the target shell vibration suppression parameter. The shell vibration level threshold and the control target of shell vibration suppression identify the allowed maximum shell vibration level, and the shell vibration can be determined to be controlled within a certain range according to the shell vibration level threshold, so that corresponding target shell vibration suppression parameters are determined.
In specific implementation, judging whether the target shell vibration level data meets a preset shell vibration level threshold value; then, under the condition that the target shell vibration level data meets a preset shell vibration level threshold, taking the audio signal to be processed as the target audio signal and outputting the target audio signal to a loudspeaker of the electronic equipment, namely, directly playing the sound without suppressing the shell vibration; and under the condition that the target shell vibration level data does not meet a preset shell vibration level threshold, calculating the target shell vibration suppression parameter according to the target shell vibration level data and the preset shell vibration level threshold, namely calculating a target shell vibration suppression parameter corresponding to shell vibration suppression of a control target reaching the preset shell vibration suppression according to the shell vibration level threshold.
Different users have different tolerance degrees on the shell vibration, and the shell vibration suppression can also have a certain influence on the audio frequency to a certain extent, so that different shell vibration level thresholds can be set according to different users and different application scenes.
In specific implementation, the user can select and set application scenes, and different application scenes correspond to different shell vibration level thresholds and also correspond to different shell vibration suppression effects. For example, the application scene may include an optimal sound quality mode, an equalization mode, a vibration-free mode, and the like, and the corresponding shell vibration suppression effects are low shell vibration suppression level, medium shell vibration suppression level, high shell vibration suppression level, and the like. The user can select different shell vibration suppression effects according to subjective experience. In the executing process, determining the current application scene parameters of the electronic equipment; and then determining a corresponding shell vibration level threshold value as a preset shell vibration level threshold value according to the current scene parameters, and determining to what extent the shell vibration needs to be suppressed according to the determined preset shell vibration level threshold value.
Step S108: and carrying out equalization processing on the audio signal to be processed according to the target shell vibration suppression parameter, obtaining an equalized target audio signal, and outputting the target audio signal to a loudspeaker of the electronic equipment.
After the target shell vibration suppression parameters are determined, the audio signal to be processed can be subjected to equalization processing according to the target shell vibration suppression parameters, namely, the equalization signals corresponding to the target shell vibration suppression parameters are applied to the audio signal to be processed, so that the target audio signal after the equalization processing is obtained. Then the target audio signal is output to the loudspeaker of the electronic equipment, and then the loudspeaker is used for sound playing, and at the moment, the shell vibration of the electronic equipment is controlled within a certain range, so that the shell vibration of the electronic equipment is effectively restrained.
Through the steps S102-S108, a target shell vibration suppression parameter corresponding to shell vibration suppression is calculated according to the input audio signal and the shell vibration level determined by the detection value of the acceleration sensor, and then the audio signal is processed according to the target shell vibration suppression parameter and then is input into the loudspeaker, so that the shell vibration is effectively suppressed.
Further, in the method for suppressing the vibration of the electronic device casing, the possible shell vibration level data is predicted in advance through the audio signal to be processed, then the actual shell vibration condition is detected through the acceleration sensor under the condition of sound external emission, whether the predicted shell vibration level data is accurate or not is determined according to the actual detection condition, then the shell vibration suppression parameters needing to be corrected are determined according to the predicted shell vibration level data and the detected shell vibration level data, and then the audio signal to be processed is processed, so that the effect of suppressing the shell vibration is achieved.
Further, in this embodiment, in order to predict the shell vibration as much as possible, as described above, the shell vibration condition may be predicted according to the audio signal, so that the corresponding shell vibration suppression parameter may be calculated, so that the shell vibration that may exist in the audio signal may be suppressed according to the shell vibration suppression parameter before the sound is played. Specifically, an initial shell vibration suppression parameter is obtained, the initial shell vibration suppression parameter is determined according to shell vibration level data predicted by an audio signal, and then the shell vibration suppression parameter is input into a loudspeaker of the electronic device after the audio signal to be processed is preprocessed according to the initial shell vibration suppression parameter, so that shell vibration is reduced, and shell vibration suppression efficiency is improved.
