Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a schematic diagram of a playback system involved in an audio playback method according to some exemplary embodiments. As shown in FIG. 1 , the playback system may include: a processor 101 , a memory 102 , a speaker 103 and a barometer 104 .

The processor 101 is connected to the memory 102 , the speaker 103 and the barometer 104 respectively. Moreover, the barometer 104 can be placed close to the speaker 103 , so that the collected air pressure parameters can be closer to the environment where the speaker 103 is located.

Specifically, after detecting the playing of the audio file, the processor 101 can obtain the air pressure parameter detected by the barometer 104, and the processor 101 can search and obtain the target audio corresponding to the air pressure parameter from the memory 102 according to the preset correspondence relationship. parameters, and then use the target audio parameters to play the audio file through the speaker 103 .

It should be noted that the processor 101 may be DSP (Digital Signal Processing, digital signal processing), the memory 102 may be MTP (Media Transfer Protocol, media transfer protocol), of course, other components may also be used as the processor 101 and the memory. 102. This embodiment of the present invention does not limit this.

Referring to FIG. 2, a flowchart of steps of an audio playback method according to an embodiment of the present invention is shown, which may specifically include the following steps:

Step 201, obtaining air pressure parameters.

The air pressure parameter is used to indicate the air pressure corresponding to the environment where the mobile terminal is currently located.

Since the mobile terminal is affected by atmospheric pressure in the process of playing the audio file, the physical characteristics of the speaker for playing the audio file will change. In order to prevent the sound of the played audio file from changing, it is necessary to use different audio parameters to play the audio file.

Therefore, when the mobile terminal plays the audio file, it needs to obtain the air pressure parameter, so as to determine the air pressure of the current environment where the mobile terminal is located according to the air parameter, so that in the subsequent steps, the mobile terminal can obtain the corresponding audio parameter according to the air pressure parameter.

Specifically, the mobile terminal can collect the air pressure of the current environment where the mobile terminal is located through a preset barometer, obtain air pressure parameters, and send the air pressure parameters to the processor of the mobile terminal, and the processor can receive the air pressure parameters, and complete Access to air pressure parameters.

It should be noted that the mobile terminal may acquire the air pressure parameter in real time, or may acquire the air pressure parameter every preset time period, which is not limited in this embodiment of the present invention.

Step 202: Acquire a target audio parameter corresponding to the air pressure parameter from at least one set of audio parameters.

After acquiring the air pressure parameters, the mobile terminal can search and obtain the target audio parameters corresponding to the currently collected air pressure parameters according to the correspondence between the pre-stored air pressure parameters and the audio parameters, so that in subsequent steps, the mobile terminal can The target audio parameter plays the audio file.

Specifically, the mobile terminal can first obtain the corresponding relationship between the air pressure parameters and the audio parameters, and in each air pressure parameter in the corresponding relationship, search for the target air pressure parameter that is consistent with the air pressure parameter obtained this time, so as to compare the air pressure parameter with the air pressure parameter obtained this time. The audio parameter corresponding to the target air pressure parameter is used as the target audio parameter.

It should be noted that the mobile terminal can determine a plurality of air pressure parameters in advance according to the detection accuracy of the barometer, the different air pressures corresponding to the user's range of activities, and the processing capability of the processor of the mobile terminal. The test is carried out in the environment of the device, and the audio parameters corresponding to each air pressure parameter are obtained, so as to establish the corresponding relationship between the air pressure parameter and the audio parameter.

Among them, the detection accuracy of the barometer can be 0.03, and the user's activity range can be different air pressures corresponding to the basin to the plateau.

Step 203: Play the audio file according to the target audio parameter.

After acquiring the target audio parameter, the mobile terminal can play the audio file according to the target audio parameter, so that the played sound will not be changed due to the change of the physical characteristics of the speaker, and the sound closer to the original quality can be obtained.

Specifically, the mobile terminal can first obtain the audio file, decode the audio file, and then convert the decoded digital signal into an analog signal, and process the analog signal through various parameters in the target audio parameters to obtain the processed analog signal. signal, and finally play the processed analog signal through the speaker to complete the playback of the audio file.

To sum up, the audio playback method provided by the embodiment of the present invention acquires the air pressure parameter, obtains the target audio parameter corresponding to the air pressure parameter from at least one set of audio parameters, and finally plays the audio file according to the target audio parameter. By changing the physical characteristics of each component of the speaker under different air pressure environments, different audio parameters are used to play audio files, which eliminates the influence caused by the changes in the physical characteristics of each component, and makes the played sound closer to reality. It improves the restoration degree of playing audio files and improves the flexibility of playing audio files.

Referring to FIG. 3, a flowchart of steps of an audio playback method according to an embodiment of the present invention is shown, which may specifically include the following steps:

Step 301, detecting whether the mobile terminal plays an audio file.

Due to the different air pressure environment, the physical properties of various components in the speaker will change, which will affect the sound played. In order to prevent the playing sound from being affected and restore the real sound of the audio file, the mobile terminal can obtain the air pressure parameter corresponding to the current environment, so as to use different audio parameters to play according to different air pressure parameters.

However, before the mobile terminal acquires the air pressure parameters, the mobile terminal needs to detect whether an audio file is being played. When the mobile terminal is playing the audio file, the mobile terminal only needs to acquire the air pressure parameters.

Specifically, the mobile terminal can detect a play operation triggered by the user, and the play operation is used to control the mobile terminal to play the audio file. When the mobile terminal detects the user-triggered playback operation, it means that the user needs to play the audio file through the mobile terminal; however, if the mobile terminal does not detect the user-triggered playback operation, it means that the mobile terminal does not play the audio file, and there is no need to obtain the audio file. The air pressure parameter corresponding to the current environment needs to continue to detect the playback operation triggered by the user, so that when the user triggers the playback operation, the air pressure parameter can be obtained according to the playback operation in time, the audio parameters can be determined, and the audio file playback can be completed.

Step 302, when the mobile terminal is playing the audio file, obtain the air pressure parameter.

This step 302 is similar to the step 201, and details are not repeated here.

Step 303: Determine the air pressure difference between the air pressure parameter and the standard air pressure parameter.

Since the air pressure of the environment where the mobile terminal is located may change, the physical characteristics of each component of the speaker will change, and the protection measures for the speaker pre-stored by the mobile terminal will lose their protective effect when the air pressure changes.

Therefore, the mobile terminal can first determine whether the air pressure corresponding to the current environment is significantly different from the standard air pressure, and determine whether the playback of the audio file by the mobile terminal in the current environment will cause damage to various components in the speaker.

Specifically, after acquiring the air pressure parameter, the mobile terminal can perform calculation according to the air pressure parameter and the preset standard air pressure parameter, obtain the air pressure difference value between the air pressure parameter and the standard air pressure parameter, and determine whether the air pressure difference value is greater than the preset value. preset safety threshold.

The preset safety threshold may be set according to the physical performance of each component of the speaker, and of course, may also be set in other manners, which is not limited in this embodiment of the present invention.

If the air pressure difference is not greater than the preset safety threshold, it means that the air pressure in the current environment of the mobile terminal is not much different from the standard air pressure, and playing audio files in the current environment will not cause damage to various components of the speaker, you can execute Step 304.

However, if the air pressure difference is greater than the preset safety threshold, it means that the air pressure in the current environment of the mobile terminal is quite different from the standard air pressure. If playing the audio file will cause irreversible damage to various components of the speaker, you need to perform steps 305.

Step 304, when the air pressure difference is not greater than the preset safety threshold, obtain a target audio parameter corresponding to the air pressure parameter from at least one set of audio parameters.

When the air pressure difference is not greater than the preset safety threshold, the mobile terminal may search from at least one set of audio parameters according to the air pressure parameter to obtain the target audio parameter corresponding to the air pressure parameter. Moreover, the target audio parameter may include a first audio parameter and a second audio parameter, the first audio parameter is an audio parameter that can be adjusted according to the environment and/or user preferences, and the second audio parameter is pre-based on different air pressure parameters Debugged audio parameters.

For example, the first audio parameter may be a sound effect, and the second audio parameter may be at least one parameter among EQ, gain, and protection algorithm.

Therefore, in the process of acquiring the target audio parameter, the mobile terminal can first display at least one parameter value corresponding to the first audio parameter to the user, and determine the parameter value corresponding to the first audio parameter according to the selection operation triggered by the user, and then according to the preset The corresponding relationship between the air pressure parameter and the second audio parameter is determined, the parameter value corresponding to the second audio parameter corresponding to the current air pressure parameter is determined, and the parameter value corresponding to each audio parameter in the target audio parameter is determined.

Optionally, the mobile terminal may display at least one parameter value corresponding to the first audio parameter to the user, and in response to a selection operation triggered by the user, determine the parameter value selected by the user from the at least one parameter value as the first audio parameter, and then determine the value of the parameter selected by the user. The second audio parameter corresponding to the air pressure parameter is determined according to the preset correspondence between the air pressure parameter and the second audio parameter.

Specifically, the mobile terminal may first display at least one parameter value corresponding to the first audio parameter to the user, so that the user may select the first audio parameter according to personal preference. The mobile terminal can detect the selection operation triggered by the user, and when detecting the selection operation triggered by the user, can respond to the selection operation and use the parameter value corresponding to the selection operation as the parameter value of the first audio parameter.

After determining the first audio parameter, the mobile terminal can obtain the corresponding relationship between the air pressure parameter and the second audio parameter, search for the air pressure parameter corresponding to the air pressure parameter of the current environment from the corresponding relationship, and then obtain the air pressure parameter corresponding to the air pressure parameter. The parameter values of the corresponding second audio parameters are finally obtained respectively, and the parameter values corresponding to the first audio parameters and the second audio parameters are obtained respectively, and the target audio parameters are obtained.

It should be noted that, in practical applications, the first audio parameter may include one audio parameter, or may include multiple audio parameters, and this embodiment of the present invention only takes the first audio parameter including one audio parameter as an example for description. The embodiment of the invention does not limit the number of audio parameters included in the first audio parameter.

Further, in the process of displaying at least one parameter value, the mobile terminal can recommend a parameter value matching the current air pressure to the user, so that the user can hear a more pleasant sound when listening to the audio file played by the mobile terminal.

For example, when the first audio parameter is sound effects, the corresponding parameter values may include ethereal sound effects, deep sound effects, and normal sound effects. If the current air pressure of the mobile terminal is lower than the standard atmospheric pressure, the user may be recommended to select ethereal sound effects; If the air pressure is higher than the standard atmospheric pressure, users can be recommended to select a low sound effect.

Step 305, when the air pressure difference is greater than the preset safety threshold, stop playing the audio file.

If the mobile terminal determines that the air pressure difference is greater than the preset safety threshold, it means that the air pressure in the current environment of the mobile terminal is quite different from the standard air pressure. If the mobile terminal plays audio files in the current environment, it will cause damage to various components of the speaker. .

Therefore, when the mobile terminal determines that the air pressure difference is greater than the preset safety threshold, it can stop playing the audio file, and prompt the user that the current air pressure and the standard air pressure are too large, and playing the audio file will cause damage to the speaker.

Further, if the interface of the mobile terminal continues to stay on the interface of playing audio files, the mobile terminal may perform steps 302 to 303 in a loop until the air pressure difference is not greater than the preset safety threshold, and then step 304 is performed.

Step 306, play the audio file according to the target audio parameters.

This step 306 is similar to the process of step 203, and details are not described here.

Step 307 , when a stop playing operation triggered by the user is detected, stop acquiring the air pressure parameter.

The stop playing operation is used to instruct the mobile terminal to stop playing the audio file.

During the process of playing the audio file according to the target audio parameter, the mobile terminal can detect the stop playing operation triggered by the user, and stop acquiring the air pressure parameter while stopping the playing of the audio file according to the stop playing operation.

Optionally, the mobile terminal may detect the stop playing operation, and stop acquiring the air pressure parameter when detecting the stop playing operation triggered by the user. Specifically, in the process of playing the audio file, the mobile terminal can detect the stop playing operation triggered by the user, and when the stop playing operation is detected, the mobile terminal can stop playing the audio file and stop acquiring the air pressure parameter.

It should be noted that, if the mobile terminal continuously acquires the air pressure parameter in real time in step 302, the mobile terminal may immediately stop acquiring the air pressure parameter after detecting the stop playing operation. However, if the mobile terminal acquires the air pressure parameter periodically, the mobile terminal will no longer acquire the air pressure parameter in the next cycle.

To sum up, the audio playback method provided by the embodiment of the present invention acquires the air pressure parameter, obtains the target audio parameter corresponding to the air pressure parameter from at least one set of audio parameters, and finally plays the audio file according to the target audio parameter. By changing the physical characteristics of each component of the speaker under different air pressure environments, different audio parameters are used to play audio files, which eliminates the influence caused by the changes in the physical characteristics of each component, and makes the played sound closer to reality. It improves the restoration degree of playing audio files and improves the flexibility of playing audio files.

Further, by showing the user at least one parameter value corresponding to the first audio parameter, and determining the parameter value of the first audio parameter according to the selection operation triggered by the user, and according to the preset correspondence between the air pressure parameter and the second audio parameter, A second audio parameter corresponding to the air pressure parameter is determined, thereby determining each parameter value of the target audio parameter. By using different methods to determine the parameter values corresponding to different audio parameters, the accuracy of the target audio parameters can be improved, thereby further optimizing the sound effects played by the mobile terminal and improving the restoration degree of the played audio files.

Further, by checking whether the mobile terminal is playing the audio file, when it is detected that the mobile terminal is playing the audio file, the air pressure parameter is obtained, which avoids the situation of obtaining the air pressure parameter when the audio file is not played, and improves the acquisition of the air pressure parameter. effectiveness.

Further, by obtaining the air pressure difference between the air pressure parameter and the standard air pressure parameter, and judging whether the air pressure difference is greater than the preset safety threshold, and then determining whether the speaker of the mobile terminal needs to be protected according to the judgment result, thereby stopping the playback. Audio files are prevented from playing audio files in the case of a large difference in air pressure, thereby causing damage to the speakers, and improving the security of playing audio files.
