Description

Technical Field

[0001] This application belongs to the field of audio technology, and in particular, relates to an audio playback method, an electronic device, a chip system, a computer-readable storage medium, and a computer program product. Background Art

[0002] In some electronic devices with audio playback functions (such as smartphones), stereo effects can be achieved through dual speakers. In some electronic devices that use an analog power amplifier (PA) to amplify audio signals, since the analog PA does not have the ability to convert digital-to-analog, a codec chip is also required to convert the digital audio signal into an analog audio signal, input the analog audio signal to the analog PA for amplification, and then output it through an audio output device (such as headphones, speakers, etc.).

[0003] In the related art, for some types of codec chips, due to design defects in their software and hardware, one speaker of the electronic device reuses the audio path of the analog headphones. Therefore, when playing audio with the analog headphones plugged in and the ringtone sounds and is played simultaneously through the analog headphones and the speaker, after turning off the ringtone, audio playback will resume in the analog headphones, but at this time, the audio in the headphone path will also leak out briefly from this speaker, resulting in sound leakage of the electronic device. Summary of the Invention

[0004] Embodiments of this application provide an audio playback method, an electronic device, a chip system, a computer-readable storage medium, and a computer program product, which can solve the problem that for some types of codec chips, due to design defects in their software and hardware, one speaker of the electronic device reuses the audio path of the analog headphones. Therefore, when playing audio with the analog headphones plugged in and the ringtone sounds and is played simultaneously through the analog headphones and the speaker, after turning off the ringtone, the audio in the headphone path will leak out briefly from the speaker, resulting in sound leakage of the electronic device.

[0005] In a first aspect, embodiments of this application provide an audio playback method, including: when an audio stream start instruction or an audio stream device switching instruction of the electronic device is obtained, determining the type of audio component corresponding to the electronic device; when the type of audio component is a preset type, determining a target output device corresponding to the audio to be played; when the target output device includes an analog headphone and a speaker, switching the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker, where the speakers include a first speaker and a second speaker, and the first speaker refers to the speaker that reuses the default audio path with the analog headphone; outputting the audio to be played through the target output device.

[0006] In this way, when the audio stream is turned on or the audio stream device is switched, according to the audio component type corresponding to the electronic device and the target output device corresponding to the audio to be played, it is determined whether the current is a sound leakage scenario caused by dual-ringing of the ringtone. If the current is a sound leakage scenario caused by dual-ringing of the ringtone, the data routing of the first speaker can be switched from the default audio path multiplexed with the analog headset to the audio path corresponding to the second speaker, so that the first speaker and the second speaker output the same audio data. Thus, after the audio to be played is turned off, other audio output through the analog headset will not leak out through the first speaker, solving the problem of sound leakage of the electronic device speaker after the ringtone is turned off in the dual-ringing ringtone scenario, protecting the user's privacy, and improving the user experience.

[0007] In a possible implementation manner of the first aspect, the above switching the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker includes:

[0008] Read the audio path configuration parameters;

[0009] When the preset string is included in the audio path configuration parameters, send a data routing switching instruction to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0010] In this way, by identifying whether the data routing of the first speaker needs to be switched through the preset string in the set audio path configuration parameters to avoid sound leakage of the speaker, the sound leakage elimination solution of the speaker can be applied to all types of electronic devices without modifying the code, improving the versatility and practicality of the speaker sound leakage elimination solution.

[0011] Optionally, in another possible implementation manner of the first aspect, the above sending a data routing switching instruction to the codec chip when the preset string is included in the audio path configuration parameters, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker includes:

[0012] When the preset string is included in the audio path configuration parameters, determine the audio stream type corresponding to the audio to be played;

[0013] When the audio stream type corresponding to the audio to be played is the preset audio stream type, send a data routing switching instruction to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0014] Thus, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific audio stream types, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, so as to further improve the accuracy of leaky sound scenario discrimination, prevent frequent switching of the speaker's data routing in unnecessary scenarios, and affect the stability of audio playback, thereby further improving the accuracy and reliability of speaker leaky sound cancellation and further enhancing the user experience.

[0015] Optionally, in another possible implementation manner of the first aspect, the determining the audio component type corresponding to the electronic device includes:

[0016] Query the device tree file corresponding to the electronic device to determine the configuration item corresponding to the audio component type;

[0017] Determine the audio component type corresponding to the electronic device according to the configuration item corresponding to the audio component type.

[0018] Thus, by pre-defining the configuration item corresponding to the audio component type of the electronic device in the device tree file corresponding to the electronic device, to directly determine whether the audio component type corresponding to the electronic device belongs to the audio component type of the leaky sound scenario through the value of this configuration item, and then determine whether to execute the leaky sound cancellation solution of this application according to the discrimination result. Therefore, regardless of whether the audio component type corresponding to the electronic device is a preset audio component type belonging to the leaky sound scenario, the leaky sound cancellation solution of the speaker of this application can be compatible, thereby improving the versatility and practicality of the leaky sound cancellation solution of the speaker.

[0019] Optionally, in another possible implementation manner of the first aspect, the audio to be played includes the audio of the left channel to be played and the audio of the right channel to be played; correspondingly, before outputting the audio to be played through the target output device, it further includes:

[0020] Mix the audio of the left channel to be played and the audio of the right channel to be played to generate the mixed audio to be played;

[0021] Correspondingly, the outputting the audio to be played through the target output device includes:

[0022] Output the mixed audio to be played through the target output device.

[0023] Thus, since the user may adjust the audio path corresponding to the second speaker to silent in some usage scenarios, if the data routing of the first speaker is switched to the audio path corresponding to the second speaker in this case, it will cause both the first speaker and the second speaker to play silent data, resulting in the inability to play the audio to be played normally. Therefore, to prevent this situation, after switching the data routing of the first speaker, the left and right channel data of the audio to be played can be mixed. Then, the first speaker and the second speaker will output the mixed audio, preventing the situation of silent external playback when there is a double ringtone. This not only eliminates the speaker sound leakage in the double ringtone scenario but also prevents the situation of silent speakers when there is a double ringtone, further improving the reliability of sound leakage elimination and further enhancing the user experience.

[0024] Optionally, in another possible implementation manner of the first aspect, the above-mentioned mixing process of the left-channel audio to be played and the right-channel audio to be played to generate the mixed audio to be played includes:

[0025] Read the audio path configuration parameters;

[0026] When the audio path configuration parameters contain a preset string, send a speaker mixing instruction to the digital signal processing (DSP) chip, so that the DSP chip mixes the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0027] In this way, by identifying whether to switch the data routing of the first speaker through a preset string in the set audio path configuration parameters to avoid speaker sound leakage, and by sending the speaker mixing processing method through the speaker mixing instruction, the sound leakage elimination solution for speakers can be applied to all types of electronic devices without modifying the code, improving the generality and practicality of the speaker sound leakage elimination solution.

[0028] Optionally, in another possible implementation manner of the first aspect, the above-mentioned step of sending a speaker mixing instruction to the DSP chip when the audio path configuration parameters contain a preset string, so that the DSP chip mixes the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played includes:

[0029] When the audio path configuration parameters contain a preset string, determine the audio stream type corresponding to the audio to be played;

[0030] When the audio stream type corresponding to the audio to be played is a preset audio stream type, send a speaker mixing instruction to the DSP chip, so that the DSP chip mixes the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0031] In this way, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific audio stream types, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to determine that when the audio stream type corresponding to the audio to be played is a preset audio stream type, then switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker, and perform mixing processing on the audio data of the left and right channels, so as to further improve the accuracy of leaky sound scene discrimination, prevent mixing in unnecessary scenes, affect the stability of audio playback, waste computing power, thereby further improving the accuracy and reliability of speaker leaky sound elimination, reducing the power consumption of the electronic device, and further enhancing the user experience.

[0032] In a second aspect, an embodiment of the present application provides an audio playback device, including: a first determination module, configured to determine the audio component type corresponding to the electronic device when an audio stream start instruction or an audio stream device switching instruction of the electronic device is obtained; a second determination module, configured to determine the target output device corresponding to the audio to be played when the audio component type is a preset type; a switching module, configured to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when the target output device includes an analog earphone and a speaker, where the speaker includes a first speaker and a second speaker, and the first speaker refers to the speaker that shares the default audio path with the analog earphone; an output module, configured to output the audio to be played through the target output device.

[0033] In this way, when the audio stream is started or the audio stream device is switched, according to the audio component type corresponding to the electronic device and the target output device corresponding to the audio to be played, it is determined whether the current is a leaky sound scene caused by double-ringing of the ringtone. If the current is a leaky sound scene caused by double-ringing of the ringtone, the data routing of the first speaker can be switched from the default audio path shared with the analog earphone to the audio path corresponding to the second speaker, so that the first speaker and the second speaker output the same audio data. Thus, after the audio to be played is turned off, other audio output through the analog earphone will not leak out through the first speaker, solving the problem of speaker leaky sound of the electronic device after the ringtone is turned off in the double-ringing ringtone scene, protecting user privacy, and enhancing the user experience.

[0034] In a possible implementation manner of the second aspect, the above switching module includes:

[0035] A first reading unit for reading audio path configuration parameters;

[0036] A first switching unit for sending a data routing switching instruction to a codec chip when a preset string is included in the audio path configuration parameters, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0037] In this way, by identifying whether the data routing of the first speaker needs to be switched through a preset string in the set audio path configuration parameters, speaker sound leakage can be avoided, so that the speaker sound leakage elimination solution can be applied to all types of electronic devices, improving the versatility and practicality of the speaker sound leakage elimination solution.

[0038] Optionally, in another possible implementation manner of the second aspect, the above-mentioned first switching unit is specifically used for:

[0039] When a preset string is included in the audio path configuration parameters, determining the audio stream type corresponding to the audio to be played;

[0040] When the audio stream type corresponding to the audio to be played is a preset audio stream type, sending a data routing switching instruction to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0041] In this way, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific audio stream types, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, so as to further improve the accuracy of leaky sound scene discrimination, prevent frequent switching of the speaker data routing in unnecessary scenes, and affect the stability of audio playback, thereby further improving the accuracy and reliability of speaker sound leakage elimination and further improving the user experience.

[0042] Optionally, in yet another possible implementation manner of the second aspect, the above-mentioned first determination module includes:

[0043] A first query unit for querying the device tree file corresponding to the electronic device to determine the configuration item corresponding to the audio component type;

[0044] A first determination unit for determining the audio component type corresponding to the electronic device according to the configuration item corresponding to the audio component type.

[0045] In this way, by pre-defining configuration items corresponding to the audio component types of the electronic device in the device tree file of the electronic device, it is possible to directly determine whether the audio component type corresponding to the electronic device belongs to the audio component type in the sound leakage scenario based on the values of the configuration items, and then determine whether to execute the sound leakage elimination solution of the present application according to the determination result. Therefore, regardless of whether the audio component type corresponding to the electronic device is a preset audio component type belonging to the sound leakage scenario, the speaker sound leakage elimination solution of the present application can be compatible, thereby improving the versatility and practicality of the speaker sound leakage elimination solution.

[0046] Optionally, in another possible implementation manner of the second aspect, the to-be-played audio includes to-be-played left-channel audio and to-be-played right-channel audio; correspondingly, the above device further includes:

[0047] A mixing module, configured to perform mixing processing on the to-be-played left-channel audio and the to-be-played right-channel audio to generate to-be-played mixed audio;

[0048] Correspondingly, the above output module includes:

[0049] A first output unit, configured to output the to-be-played mixed audio through a target output device.

[0050] In this way, since in some usage scenarios, the user may adjust the audio path corresponding to the second speaker to be silent, so in this case, if the data routing of the first speaker is switched to the audio path corresponding to the second speaker, it will cause both the first speaker and the second speaker to play silent data, resulting in the to-be-played audio not being played normally. Therefore, to prevent this situation, after switching the data routing of the first speaker, the left and right channel data of the to-be-played audio can be mixed, then the first speaker and the second speaker will output the mixed audio, preventing the situation of no sound when the ringtone sounds twice, thereby not only eliminating the speaker sound leakage in the ringtone double-ring scenario, but also preventing the situation of no sound from the speaker when the ringtone sounds twice, further improving the reliability of sound leakage elimination and further enhancing the user experience.

[0051] Optionally, in another possible implementation manner of the second aspect, the above mixing module includes:

[0052] A second reading unit, configured to read audio path configuration parameters;

[0053] A first mixing unit, configured to send a speaker mixing instruction to the DSP chip when the audio path configuration parameters contain a preset string, so that the DSP chip performs mixing processing on the to-be-played left-channel audio and the to-be-played right-channel audio according to the speaker mixing instruction to generate to-be-played mixed audio.

[0054] In this way, by identifying whether it is necessary to switch the data routing of the first speaker through a preset string in the set audio path configuration parameters to avoid speaker sound leakage, and by sending the speaker mixing instruction to the DSP chip to implement the mixing processing method of the speaker, the solution for eliminating speaker sound leakage can be applied to all types of electronic devices, improving the universality and practicality of the speaker sound leakage elimination solution.

[0055] Optionally, in another possible implementation manner of the second aspect, the above first mixing unit is specifically configured to:

[0056] When a preset string is included in the audio path configuration parameters, determine the audio stream type corresponding to the audio to be played;

[0057] When the audio stream type corresponding to the audio to be played is a preset audio stream type, send a speaker mixing instruction to the DSP chip, so that the DSP chip performs mixing processing on the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0058] In this way, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific audio stream types, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, and perform mixing processing on the audio data of the left and right channels, so as to further improve the accuracy of leaky sound scene discrimination, prevent mixing in unnecessary scenes, affect the stability of audio playback, waste computing power, thereby further improving the accuracy and reliability of speaker sound leakage elimination, reducing the power consumption of the electronic device, and further improving the user experience.

[0075] The audio playing method, device, electronic device, chip system, storage medium and computer program provided by the present application will be described in detail below with reference to the accompanying drawings.

[0076] Please refer to Figure 1 , Figure 1 It is a schematic flowchart of an audio playing method provided by an embodiment of the present application. The method may include the following parts or all of the content:

[0077] Step 101: When an audio stream start instruction or an audio stream device switching instruction of the electronic device is obtained, determine the audio component type corresponding to the electronic device.

[0078] It should be noted that the audio playing method of the embodiment of the present application may be executed by the audio playing device of the embodiment of the present application. The audio playing device of the embodiment of the present application may be configured in any electronic device with a display function to execute the audio playing method of the embodiment of the present application. For example, the audio playing device of the embodiment of the present application may be configured in electronic devices such as mobile phones, computers, and wearable devices to eliminate the sound leakage of the speaker.

[0079] It should be noted that the operating system installed in the electronic device in the embodiment of the present application is not limited, and may be an Android system, a Windows Phone (WP) operating system, an IOS system, etc. Exemplarily, for the convenience of description, the Android system is used for subsequent description in the embodiment of the present application.

[0080] First, the cause of the technical problem to be solved by the present application and the applicable scenarios of the present application will be described:

[0081] In some electronic devices that use an analog PA to amplify audio signals, since the analog PA does not have the ability to convert digital signals to analog signals, a codec chip is also required to convert the digital audio signal into an analog audio signal, input the analog audio signal to the analog PA for amplification, and then output it through an audio output device (such as headphones, speakers, etc.). For such an electronic device that combines a codec chip and a dual analog PA to achieve a stereo design, a speaker sound leakage problem will occur when using certain types of codec chips. For example, when playing music with an analog headphone plugged in and an alarm rings, the alarm will play simultaneously through the headphone and the speaker. After turning off the alarm, the music will resume playing through the headphone, and at this time, the music sound will briefly leak out from the upper speaker. This problem is caused by the combined limitations of hardware and software.

[0082] In terms of hardware, there are hardware design flaws in certain types of codec chips. For example, Figure 2 as shown, this codec chip has only 3 input ports: the left headphone channel input (IN1_HPHL), the right headphone channel input (IN2_HPHR), and the speaker input (IN3_AUX), but it needs to support 4 output ports: the earpiece (EAR), the left headphone channel output (HPHL), the right headphone channel output (HPHR), and the speaker output (AUX) (wherein, the earpiece in the embodiments of the present application can also be referred to as the upper speaker, and the speaker can also be referred to as the lower speaker). To achieve stereo characteristics, the upper speaker (EAR) can be multiplexed with the left headphone channel (HPHL) for the audio path as Figure 2 shown.

[0083] In terms of software, analog headphones and speakers have different backends (BE). Due to the limitations of other characteristics and framework layer customization strategies, analog headphone devices and speaker devices cannot be configured with the same BE in the DSP. Since their BEs are different and they do not compete for DSP ports, when switching between devices involving analog headphones and speakers, only the required device will be switched to, and the other device path will not be forced to close, but will automatically close after waiting for a period of time (such as 3 seconds) according to the Android mechanism.

[0084] Therefore, due to the above-mentioned software and hardware limitations, there will be a problem of leakage of the upper speaker in the ringtone double-ring scenario. For example, the alarm ringtone is played simultaneously through analog headphones and speakers. After turning off the alarm, music resumes playing on the analog headphones. At this time, there is no audio stream on the speaker, but because the BE of the upper speaker is different from that of the analog headphones, it will not be forced to close and will still be open for 3 seconds. As Figure 3 shown, during this period, since the audio path of the left headphone channel is multiplexed with the upper speaker, the audio data 310 (i.e., music) of the left headphone channel will be played simultaneously on the left headphone channel and the upper speaker, resulting in sound leakage.

[0085] Among them, the audio stream opening instruction can refer to the instruction to open the audio stream when there is no audio being played in the electronic device. For example, when the electronic device is not playing any audio, if the user opens a music software to play music, opens a video software to play a video, opens a short video software to play a short video, plays voice information or video information in a social software, or plays the recorded data stored in the electronic device, etc., it can be determined that the audio stream opening instruction of the electronic device is obtained. Or, when the electronic device is not playing any audio, if the alarm rings, the incoming call rings, or a message notification is triggered, it can also be determined that the audio stream opening instruction of the electronic device is obtained.

[0086] Among them, the audio stream device switching instruction may refer to an instruction for switching the output device of the audio stream when there is an audio being played in the electronic device. For example, when playing music through the speaker and the user connects headphones, the output device of the music is switched from the speaker to the headphones at this time, and it can be determined that an audio stream device switching instruction is obtained; another example is that when the alarm rings while playing music through the headphones, the audio stream corresponding to the alarm ringtone needs to be played through the speaker and the headphones simultaneously, that is, the output device of the audio stream is switched from the headphones to the headphones and the speaker, and it can be determined that an audio stream device switching instruction is obtained.

[0087] It should be noted that the types and triggering scenarios of the above-listed audio stream enabling instructions and audio stream device switching instructions are only exemplary and should not be regarded as a limitation to this application. In actual use, the types and triggering scenarios of the audio stream enabling instructions and audio stream device switching instructions can be determined according to actual needs and specific application scenarios, and the embodiments of this application do not make any limitations in this regard.

[0088] Among them, the audio component type may include the type of the codec chip and the type of the PA.

[0089] In the embodiments of this application, each time an audio stream enabling instruction and an audio stream device switching instruction are obtained, that is, each time audio playback is started or the audio output device is switched, the audio component type corresponding to the electronic device can be determined to determine whether the audio component type corresponding to the electronic device is the audio component type that causes speaker sound leakage, so as to determine whether subsequent processing for eliminating speaker sound leakage needs to be performed according to the subsequent steps of the embodiments of this application.

[0090] Furthermore, the configuration item corresponding to the audio component type of the electronic device can be predefined in the device tree file corresponding to the electronic device, so as to directly determine whether the audio component type corresponding to the electronic device belongs to the audio component type in the sound leakage scenario through the value of this configuration item, and then determine whether to execute the sound leakage elimination solution of this application according to the determination result. Therefore, regardless of whether the audio component type corresponding to the electronic device belongs to the preset audio component type in the sound leakage scenario, the sound leakage elimination solution of this application can be compatible, thereby improving the generality and practicability of the sound leakage elimination solution of the speaker. That is, in a possible implementation manner of the embodiments of this application, the above step 101 may include:

[0091] Query the device tree file corresponding to the electronic device to determine the configuration item corresponding to the audio component type;

[0092] Determine the audio component type corresponding to the electronic device according to the configuration item corresponding to the audio component type.

[0093] As a possible implementation, configuration items corresponding to the audio component type can be customized in the device tree file of the electronic device, and the value of the configuration item can be determined in advance according to whether the type of the audio component installed in the electronic device is a preset type that causes speaker sound leakage. For example, if the type of the audio component installed in the electronic device is the preset type, the value of the configuration item can be determined in advance as the first preset value (such as 1); if the type of the audio component installed in the electronic device is not the preset type, the value of the configuration item can be determined in advance as the first preset value (such as 0). Each time the electronic device plays audio or switches the audio output device, the value of the configuration item can be queried, and the audio component type corresponding to the electronic device can be determined according to the value of the configuration item. For example, if the value of the configuration item is the first preset value, it can be determined that the audio component type corresponding to the electronic device is the preset type, and the current situation may cause a sound leakage problem; if the value of the configuration item is the second preset value, it can be determined that the audio component type corresponding to the electronic device is not the preset type, and the current situation will not cause a sound leakage problem.

[0094] For example, Figure 2 When the codec chip of type A and the dual analog PA shown in the figure are combined to achieve speaker stereo, it will cause a speaker sound leakage problem. Then, the type of the codec chip being type A and the type of the PA being an analog PA can be used as the preset type. Thus, when the type of the codec chip installed in the electronic device is type A and the type of the PA is an analog PA, the value of the configuration item corresponding to the audio component type in the device tree file can be determined as 1; when the type of the codec chip installed in the electronic device is not type A or the type of the PA is not an analog PA, the value of the configuration item corresponding to the audio component type in the device tree file can be determined as 0.

[0095] It should be noted that the above example is only exemplary and should not be regarded as a limitation to this application. In actual use, according to actual needs and specific application scenarios, any audio component type that may cause speaker sound leakage can be determined as the preset type, and the embodiments of this application do not make any limitations in this regard.

[0096] Step 102, when the audio component type is the preset type, determine the target output device corresponding to the audio to be played.

[0097] Among them, the preset type may refer to the audio component type that may cause speaker sound leakage problems in the electronic device.

[0098] Among them, the audio to be played can refer to the audio data that needs to be output through the audio output device in the electronic device currently. For example, if the user currently opens a music player software to play music, the audio to be played can be the music currently played by the user; another example, if the electronic device currently receives an incoming call, the audio to be played can be the incoming call ringtone; another example, if the alarm clock set in the electronic device reaches the ringing time currently, the audio to be played can be the alarm clock ringtone, and so on.

[0099] Among them, the target output device can refer to the audio output device in the electronic device that is currently used to output the audio to be played. For example, if the user currently opens a music player software to play music and the electronic device is not connected to headphones, the target output device corresponding to the audio to be played can be the speaker; another example, if the user currently opens a music player software to play music and the electronic device is connected to headphones, the target output device corresponding to the audio to be played can be the headphones; another example, if the alarm clock set in the electronic device reaches the ringing time currently and the electronic device is not connected to headphones, the target output device corresponding to the audio to be played can be the speaker; another example, if the alarm clock set in the electronic device reaches the ringing time currently and the electronic device is connected to headphones, the target output device corresponding to the audio to be played can be the speaker and the headphones.

[0100] It should be noted that the above examples are only exemplary and should not be regarded as a limitation to this application. In actual use, according to actual needs and specific application scenarios, any audio that needs to be played currently in the electronic device can be determined as the audio to be played, and the embodiments of this application do not make any limitations thereto.

[0101] In the embodiments of this application, if the audio component type corresponding to the electronic device is a preset type, it can be determined that there may be a problem of speaker sound leakage in the electronic device, and the subsequent steps of the embodiments of this application can be continued to eliminate speaker sound leakage when needed; if the audio component type corresponding to the electronic device is not a preset type, it can be determined that there is no problem of speaker sound leakage in the electronic device, and the subsequent steps of the embodiments of this application can not be executed, and the default audio processing process of the electronic device can be followed for processing and outputting the audio to be played.

[0102] As a possible implementation, through the above analysis of the technical problems to be solved by this application, it can be known that when the audio component type corresponding to the electronic device is a combination of a codec chip and a dual analog PA, if the audio needs to be played through the speaker and the analog headphone simultaneously, then when the audio is turned off, it will cause the speaker that shares the audio path with the headphone to leak sound. Therefore, after determining that the audio component type corresponding to the electronic device is the preset type, the target output device corresponding to the audio to be played can be further determined to judge whether the audio to be played needs to be played through the speaker and the analog headphone simultaneously. If it is determined that the audio to be played needs to be played through the speaker and the analog headphone simultaneously, it can be determined that the speaker may leak sound when the audio to be played is turned off; if it is determined that the audio to be played does not need to be played through the speaker and the analog headphone simultaneously, it can be determined that the speaker will not leak sound when the audio to be played is turned off.

[0103] Step 103, when the target output device includes an analog headphone and a speaker, switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker, where the speakers include the first speaker and the second speaker, and the first speaker refers to the speaker that shares the default audio path with the analog headphone.

[0104] Among them, the analog headphone can include a three - segment analog headphone and a four - segment analog headphone.

[0105] Among them, the electronic device may include two speakers, the first speaker and the second speaker, and the first speaker is the speaker that shares the audio path with the analog headphone, and the default audio path is the audio path shared between the first speaker and the analog headphone. For example, as Figure 2 shown, since the upper speaker shares the audio path with the left channel of the headphone, the first speaker can be the upper speaker, the second speaker can be the lower speaker, and the default audio path can be the left channel of the headphone.

[0106] In an embodiment of the present application, if the target output device corresponding to the audio to be played is one of an analog headphone or a speaker, or although the target output device includes both a headphone and a speaker, but the headphone is a digital headphone, it can be determined that there is no speaker sound leakage problem in the electronic device, and the subsequent steps of the embodiment of the present application can be not executed, and the audio to be played can be processed and output according to the default audio processing flow of the electronic device. If the target output device corresponding to the audio to be played includes an analog headphone and a speaker, it can be determined that the audio to be played needs to be played through the analog headphone and the speaker simultaneously, which is a ringtone double-ring scenario. Then, when the audio to be played is turned off, the first speaker that multiplexes the default audio path with the analog headphone may have sound leakage. Therefore, the connection between the first speaker and the default audio path can be cut off, and the data routing of the first speaker can be switched to the audio path corresponding to the second speaker, so that the first speaker and the second speaker multiplex the audio path. Thus, after the audio to be played is turned off, since there is no data in the audio path corresponding to the second speaker, even if the device path of the first speaker is not closed, the first speaker has no audio data to output and there will be no sound leakage, thereby eliminating the speaker sound leakage in the ringtone double-ring scenario.

[0107] For example, as Figure 4 shown, since the upper speaker multiplexes the audio path with the left channel of the headphone, the first speaker is the upper speaker, the second speaker is the lower speaker, and the default audio path is the left channel of the headphone. Then, when it is determined that the target output device corresponding to the audio to be played includes an analog headphone and a speaker, the path between the upper speaker and the left channel of the headphone can be cut off and switched to multiplex the path with the second speaker, and the data routing of the lower speaker is copied to the upper speaker path. Finally, the upper speaker and the lower speaker will play the same audio. And, as Figure 5 shown, after the audio to be played ends, the device paths of the upper speaker and the lower speaker can remain open for 3 seconds. At this time, if there is an audio stream (such as music) to be played in the analog headphone, it will continue to play, and the audio stream is normally played from HPHL and HPHR; due to the change in the data routing of the upper speaker, the device paths are decoupled, and there is no data in the upper speaker path during these 3 seconds, and there will no longer be an upper speaker sound leakage problem.

[0108] Furthermore, it can be indicated whether to switch the data routing of the first speaker through a preset string in the set audio path configuration parameters to avoid speaker sound leakage, so that the speaker sound leakage elimination solution can be applicable to all types of electronic devices without modifying the code, improving the versatility and practicality of the speaker sound leakage elimination solution. That is, in a possible implementation manner of the embodiment of the present application, the above step 103 may include:

[0109] Read the audio path configuration parameters;

[0110] When a preset string is included in the audio path configuration parameter, a data routing switching instruction is sent to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0111] Among them, the audio path configuration parameter may refer to a parameter inherent in the electronic device system that allows customization of the audio path of the audio output device. For example, the audio path configuration parameter can be a custom key.

[0112] As a possible implementation, when it is determined that the audio component type corresponding to the electronic device is a preset type and the target output device corresponding to the audio to be played includes an analog headphone and a speaker, a preset string can be written in the audio path configuration parameter. Then, the electronic device can read the audio path configuration parameter in the hardware abstraction layer (HAL) to determine whether the preset string is included in the audio path configuration parameter; if the preset string is included in the audio path configuration parameter, it can be determined that the current is a speaker sound leakage scenario, and a data routing switching instruction can be sent to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker according to the data routing switching instruction.

[0113] Furthermore, since the audio streams that need to be played simultaneously in the speaker and the headphone are usually several specific audio stream types, such as incoming call ringtones, alarm clock ringtones, etc., therefore, when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, the data routing corresponding to the first speaker can be switched from the default audio path to the audio path corresponding to the second speaker, so as to further improve the accuracy of the sound leakage scenario discrimination, prevent the frequent switching of the speaker data routing in unnecessary scenarios, affect the stability of the audio playback, and thus further improve the accuracy and reliability of the speaker sound leakage elimination, and further improve the user experience. That is, in a possible implementation of the embodiment of the present application, the above-mentioned step of sending a data routing switching instruction to the codec chip when a preset string is included in the audio path configuration parameter, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker, may include:

[0114] When a preset string is included in the audio path configuration parameter, determine the audio stream type corresponding to the audio to be played;

[0115] When the audio stream type corresponding to the audio to be played is a preset audio stream type, send a data routing switch instruction to the codec chip, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0116] Among them, the preset audio stream type may refer to the audio stream type that will be played through the analog headset and the speaker at the same time when the electronic device is connected to the analog headset. For example, the audio stream type lowlatency corresponding to the alarm ringtone, the audio stream type deepbuffer corresponding to the incoming call ringtone, etc., but not limited to this.

[0117] As a possible implementation, if it is determined that the audio path configuration parameter contains a preset string and the audio stream type corresponding to the audio to be played is a preset audio stream type, it can be determined that the current is a double-ring scenario for the ringtone, which may cause the problem of speaker sound leakage. Then, a data routing switch instruction can be sent to the codec, and the data routing switch instruction can be made effective, so that the codec chip can switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker according to the data routing switch instruction. If the audio path configuration parameter does not contain the preset string or the audio stream type corresponding to the audio to be played is not the preset audio stream type, it can be determined that there will be no speaker sound leakage problem currently, that is, there is no need to switch the data routing corresponding to the first speaker. Then, a data routing switch instruction can not be sent to the codec chip, and the subsequent steps of the embodiments of the present application can not be executed, and the default audio processing process of the electronic device can be followed for processing and outputting the audio to be played.

[0118] Step 104, output the audio to be played through the target output device.

[0119] In the embodiments of the present application, when it is determined that there may be a problem of speaker sound leakage in the electronic device currently, after switching the data routing of the first speaker, decoupling the first speaker from the headphone path, and multiplexing the audio path of the first speaker and the second speaker, the audio to be played can be output through the target output device (such as the analog headset and the first speaker, the second speaker), so that the audio to be played is played through the analog headset and the speaker at the same time. And after the audio to be played ends, since there is no data in the audio path corresponding to the second speaker, the first speaker will not leak sound when the device path is not cut off.

[0120] The audio playback method provided by the embodiment of the present application determines whether the current is a sound leakage scenario caused by double-ringing of the ringtone when the audio stream is turned on or the audio stream device is switched, according to the audio component type corresponding to the electronic device and the target output device corresponding to the audio to be played. If the current is a sound leakage scenario caused by double-ringing of the ringtone, the data routing of the first speaker can be switched from the default audio path multiplexed with the analog headset to the audio path corresponding to the second speaker, so that the first speaker and the second speaker output the same audio data. Thus, after the audio to be played is turned off, other audio output through the analog headset will not leak out through the first speaker, solving the problem of sound leakage of the electronic device speaker after the ringtone is turned off in the double-ringing ringtone scenario, protecting the user privacy, and improving the user experience.

[0121] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of the audio playback method provided by another embodiment of the present application. The method may include the following parts or all of the content:

[0122] Step 601, when an audio stream start instruction or an audio stream device switching instruction of the electronic device is obtained, determine the audio component type corresponding to the electronic device.

[0123] Step 602, when the audio component type is a preset type, determine the target output device corresponding to the audio to be played, where the audio to be played includes the left-channel audio to be played and the right-channel audio to be played.

[0124] Step 603, when the target output device includes an analog headset and a speaker, switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker, where the speaker includes the first speaker and the second speaker, and the first speaker refers to the speaker that multiplexes the default audio path with the analog headset.

[0125] For the specific implementation process and principle of the above steps 601-603, reference may be made to the detailed description of the above embodiment, which will not be elaborated here.

[0126] Step 604, perform a mixing process on the left-channel audio to be played and the right-channel audio to be played to generate a mixed audio to be played.

[0127] In the embodiments of the present application, in some usage scenarios, the user may adjust the audio path corresponding to the second speaker to silent (for example, in the channel equalization function, adjust to the most extreme situation to make the right channel silent). Therefore, in this case, if the data routing of the first speaker is switched to the audio path corresponding to the second speaker, it will cause both the first speaker and the second speaker to play silent data, resulting in the inability to play the audio to be played normally. Therefore, to prevent this situation, after switching the data routing of the first speaker, the left and right channel data of the audio to be played can be mixed. Then, the first speaker and the second speaker will output the mixed audio to be played, preventing the situation of silent external speaker when there is a double ringtone. This not only eliminates the speaker sound leakage in the double ringtone scenario but also prevents the situation of silent speakers when there is a double ringtone, further improving the reliability of sound leakage elimination and further enhancing the user experience.

[0128] As Figure 7 shown, it is a flowchart for mixing the left and right channels of the audio to be played. After mixing the left channel audio to be played and the right channel audio to be played, since the mixed audio to be played generated contains the left channel audio to be played, even if the right channel audio to be played is silent, the mixed audio to be played will not be silent data. Therefore, by playing the mixed audio to be played through the first speaker and the second speaker, the first speaker and the second speaker can emit sound normally, ensuring that the ringtone will not be silent when the channel equalization is adjusted to the most extreme situation.

[0129] Furthermore, it can be indicated whether to switch the data routing of the first speaker through a preset string in the set audio path configuration parameters to avoid speaker sound leakage, and the mixing processing method of the speaker is sent through the speaker mixing instruction, so that the sound leakage elimination solution of the speaker can be applied to all types of electronic devices without modifying the code, improving the versatility and practicality of the speaker sound leakage elimination solution. That is, in a possible implementation manner of the embodiments of the present application, step 604 above may include:

[0130] Read the audio path configuration parameters;

[0131] When the preset string is included in the audio path configuration parameters, send a speaker mixing instruction to the DSP chip, so that the DSP chip mixes the left channel audio to be played and the right channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0132] Among them, the audio path configuration parameters may refer to the parameters in the electronic device system that are inherent and allow customization for configuring the audio path of the audio output device. For example, the audio path configuration parameter may be custom key.

[0133] Among them, the speaker mixing instruction can refer to an instruction inherent in the electronic device system that allows customization of the configuration of the audio path in the DSP. For example, the speaker mixing instruction can be implemented in the form of graph key-value. As an example, in the speaker mixing instruction, a pair of key-value pairs can be used to specify that the device to be mixed is the speaker, and another pair of key-value pairs can be used to specify the specific method of mixing the audio path corresponding to the speaker, that is, specifying to mix the left-channel audio and the right-channel audio corresponding to the speaker.

[0134] As a possible implementation, when it is determined that the audio component type corresponding to the electronic device is a preset type and the target output device corresponding to the audio to be played includes an analog headphone and a speaker, a preset string can be written into the audio path configuration parameter. Then, the electronic device can read the audio path configuration parameter in the HAL layer to determine whether the preset string is included in the audio path configuration parameter; if the preset string is included in the audio path configuration parameter, it can be determined that the current is a speaker sound leakage scenario, and in the previous step, the data routing corresponding to the first speaker has been switched from the default audio path to the audio path corresponding to the second speaker, so there may be a problem of no external sound currently. Therefore, a speaker mixing instruction can be sent to the DSP chip, so that the DSP chip can mix the left-channel audio to be played and the right-channel audio to be played according to the audio output device and the mixing method specified in the speaker mixing instruction to generate the mixed audio to be played.

[0135] Furthermore, since the audio streams that need to be played simultaneously in the speaker and the headphone are usually several specific types of audio streams, such as incoming call ringtones, alarm clock ringtones, etc., therefore, when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, the data routing corresponding to the first speaker can be switched from the default audio path to the audio path corresponding to the second speaker, and the audio data of the left and right channels can be mixed to further improve the accuracy of the sound leakage scenario discrimination, prevent mixing in unnecessary scenarios, affect the stability of audio playback, waste computing power, thereby further improving the accuracy and reliability of speaker sound leakage elimination, reducing the power consumption of the electronic device, and further improving the user experience. That is, in a possible implementation of the embodiment of the present application, when the preset string is included in the audio path configuration parameter, sending a speaker mixing instruction to the DSP chip so that the DSP chip mixes the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played can include:

[0136] When the preset string is included in the audio path configuration parameter, determining the audio stream type corresponding to the audio to be played;

[0137] When the audio stream type corresponding to the audio to be played is a preset audio stream type, send a speaker mixing instruction to the DSP chip, so that the DSP chip mixes the left-channel audio to be played and the right-channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0138] Among them, the preset audio stream type may refer to the audio stream type that will be played through both the analog headset and the speaker when the electronic device is connected to the analog headset. For example, the audio stream type lowlatency corresponding to the alarm ringtone, the audio stream type deepbuffer corresponding to the incoming call ringtone, etc., but not limited to this.

[0139] As a possible implementation, if it is determined that the audio path configuration parameter contains a preset string and the audio stream type corresponding to the audio to be played is a preset audio stream type, it can be determined that the current is a double-ringing scenario for the ringtone, which may cause the problem of speaker sound leakage. And the data routing corresponding to the first speaker has been switched from the default audio path to the audio path corresponding to the second speaker in the foregoing steps, so there may be a problem of no external sound at present. Therefore, a speaker mixing instruction can be sent to the DSP chip, so that the DSP chip can mix the left-channel audio to be played and the right-channel audio to be played according to the audio output device and the mixing method specified in the speaker mixing instruction to generate the mixed audio to be played. If the audio path configuration parameter does not contain the preset string or the audio stream type corresponding to the audio to be played is not the preset audio stream type, it can be determined that there will be no speaker sound leakage problem at present, that is, there is no need to switch the data routing corresponding to the first speaker, so the speaker mixing instruction may not be sent to the DSP chip, and the audio to be played can be processed and output according to the default audio processing flow of the electronic device.

[0140] Step 605, output the mixed audio to be played through the target output device.

[0141] In an embodiment of the present application, when it is determined that the electronic device may have a speaker sound leakage problem currently, after switching the data routing of the first speaker to decouple the first speaker from the headphone path and to multiplex the audio path of the first speaker and the second speaker, and after mixing the audio to be played on the left channel and the audio to be played on the right channel, the mixed audio to be played can be output through the target output device (such as an analog headphone, the first speaker, and the second speaker), so that the audio to be played is played through the analog headphone and the speaker simultaneously. And after the audio to be played ends, since there is no data in the audio path corresponding to the second speaker, the first speaker will not have sound leakage when the device path is not cut off; moreover, since the mixed audio to be played generated contains the audio to be played on the left channel, even if the audio to be played on the right channel is silent, the mixed audio to be played will not be silent data, thus ensuring that even when the channel balance is adjusted to the most extreme situation, the ringtone played externally will not be silent.

[0142] In the audio playback method provided by the embodiment of the present application, in some usage scenarios, the user may adjust the audio path corresponding to the second speaker to be silent (for example, in the channel balance function, adjust to the most extreme situation to make the right channel silent). Therefore, in this case, if the data routing of the first speaker is switched to the audio path corresponding to the second speaker, it will cause both the first speaker and the second speaker to play silent data, resulting in the inability to play the audio to be played normally. Therefore, to prevent this situation, after switching the data routing of the first speaker, the left and right channel data of the audio to be played can be mixed, and then the first speaker and the second speaker will output the mixed audio to be played, preventing the situation of silent external playback when the ringtone rings twice. Thus, not only the speaker sound leakage in the ringtone double-ring scenario is eliminated, but also the situation of silent speakers when the ringtone rings twice is prevented, further improving the reliability of sound leakage elimination and further enhancing the user experience.

[0143] Please refer to Figure 8 , Figure 8 which is a schematic flowchart of the audio playback method provided by another embodiment of the present application, including the following steps:

[0144] Step 801, obtaining an audio stream start instruction or an audio stream device switching instruction;

[0145] Step 802, checking the configuration item to determine whether the audio component type corresponding to the electronic device is a preset type; if so, execute Step 803; otherwise, end.

[0146] Step 803, checking whether the target output device corresponding to the audio to be played includes an analog headphone and a speaker; if so, execute Step 804; otherwise, end.

[0147] Step 804: Send a data routing switch instruction and a speaker mixing instruction;

[0148] Step 805: Check whether the audio stream type corresponding to the audio to be played is a preset audio stream type; if so, execute Steps 806 and 807; otherwise, end;

[0149] Step 806: Switch the data routing corresponding to the first speaker to the audio path corresponding to the second speaker through the codec chip;

[0150] Step 807: Mix the left channel audio to be played and the right channel audio to be played through the DSP chip to generate the mixed audio to be played;

[0151] Step 808: Play the mixed audio to be played through the speaker.

[0152] It should be noted that Figure 8 For the other specific implementation processes and principles of the illustrated embodiments, reference may be made to the detailed descriptions of the above embodiments, which will not be elaborated herein.

[0153] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0154] Corresponding to the audio playback method described in the above embodiments, Figure 9 The block diagram of the audio playback device provided by the embodiments of the present application is shown. For the sake of convenience of description, only the parts related to the embodiments of the present application are shown.

[0155] Referring to Figure 9 , the device 90 includes:

[0156] A first determination module 91, configured to determine the audio component type corresponding to the electronic device when an audio stream start instruction or an audio stream device switch instruction of the electronic device is obtained;

[0157] A second determination module 92, configured to determine the target output device corresponding to the audio to be played when the audio component type is a preset type;

[0158] A switching module 93, configured to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when the target output device includes an analog headphone and a speaker, where the speaker includes a first speaker and a second speaker, and the first speaker refers to the speaker that shares the default audio path with the analog headphone;

[0159] An output module 94, configured to output the audio to be played through the target output device.

[0160] In actual use, the audio playback device provided by the embodiments of the present application can be configured in any electronic device to execute the foregoing audio playback method.

[0161] The audio playback device provided by the embodiments of the present application determines whether the current is a leakage sound scenario caused by double-ringing of the ringtone when the audio stream is turned on or the audio stream device is switched, according to the audio component type corresponding to the electronic device and the target output device corresponding to the audio to be played. If the current is a leakage sound scenario caused by double-ringing of the ringtone, the data routing of the first speaker can be switched from the default audio path multiplexed with the analog headset to the audio path corresponding to the second speaker, so that the first speaker and the second speaker output the same audio data. Thus, after the audio to be played is turned off, other audio output through the analog headset will not leak out through the first speaker, solving the problem of leakage sound of the electronic device speaker after the ringtone is turned off in the double-ringing ringtone scenario, protecting the user privacy and improving the user experience.

[0162] In a possible implementation manner of the present application, the above switching module 93 includes:

[0163] A first reading unit, configured to read audio path configuration parameters;

[0164] A first switching unit, configured to send a data routing switching instruction to the codec chip when the audio path configuration parameters include a preset string, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0165] In this way, whether to switch the data routing of the first speaker is identified by a preset string in the set audio path configuration parameters to avoid speaker leakage sound, so that the speaker leakage sound elimination solution can be applicable to all types of electronic devices, improving the versatility and practicality of the speaker leakage sound elimination solution.

[0166] Further, in another possible implementation manner of the present application, the above first switching unit is specifically configured to:

[0167] Determine the audio stream type corresponding to the audio to be played when the audio path configuration parameters include a preset string;

[0168] Send a data routing switching instruction to the codec chip when the audio stream type corresponding to the audio to be played is a preset audio stream type, so that the codec chip switches the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker.

[0169] Thus, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific types of audio streams, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, so as to further improve the accuracy of leaky sound scenario discrimination, prevent frequent switching of the data routing of the speaker in unnecessary scenarios, and affect the stability of audio playback, thereby further improving the accuracy and reliability of speaker leaky sound cancellation and further enhancing the user experience.

[0170] Further, in another possible implementation manner of the present application, the above-mentioned first determination module 91 includes:

[0171] The first query unit is used to query the device tree file corresponding to the electronic device to determine the configuration item corresponding to the audio component type;

[0172] The first determination unit is used to determine the audio component type corresponding to the electronic device according to the configuration item corresponding to the audio component type.

[0173] In this way, by pre-defining the configuration item corresponding to the audio component type of the electronic device in the device tree file corresponding to the electronic device, to directly determine whether the audio component type corresponding to the electronic device belongs to the audio component type of the leaky sound scenario through the value of this configuration item, and then determine whether to execute the leaky sound cancellation solution of the present application according to the determination result. Therefore, no matter whether the audio component type corresponding to the electronic device belongs to the preset audio component type of the leaky sound scenario, the leaky sound cancellation solution of the speaker of the present application can be compatible, thereby improving the versatility and practicability of the leaky sound cancellation solution of the speaker.

[0174] Further, in another possible implementation manner of the present application, the above-mentioned audio to be played includes the left channel audio to be played and the right channel audio to be played; correspondingly, the above-mentioned device 90 further includes:

[0175] The mixing module is used to perform mixing processing on the left channel audio to be played and the right channel audio to be played to generate the mixed audio to be played;

[0176] Correspondingly, the above-mentioned output module 94 includes:

[0177] The first output unit is used to output the mixed audio to be played through the target output device.

[0178] Thus, since the user may adjust the audio path corresponding to the second speaker to silent in some usage scenarios, if the data routing of the first speaker is switched to the audio path corresponding to the second speaker in this case, it will cause both the first speaker and the second speaker to play silent data, resulting in the inability to play the audio to be played normally. Therefore, to prevent this situation from occurring, after switching the data routing of the first speaker, the left and right channel data of the audio to be played can be mixed, and then the first speaker and the second speaker will output the mixed audio, preventing the situation of silent external speaker when the ringtone sounds twice. This not only eliminates the speaker sound leakage in the ringtone double - sound scenario but also prevents the situation of silent speakers when the ringtone sounds twice, further improving the reliability of sound leakage elimination and further enhancing the user experience.

[0179] Further, in another possible implementation manner of the present application, the above - mentioned mixing module includes:

[0180] A second reading unit, configured to read audio path configuration parameters;

[0181] A first mixing unit, configured to send a speaker mixing instruction to the DSP chip when the audio path configuration parameters contain a preset string, so that the DSP chip mixes the left - channel audio to be played and the right - channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0182] Thus, by identifying whether the data routing of the first speaker needs to be switched through a preset string in the set audio path configuration parameters to avoid speaker sound leakage, and by sending the speaker mixing instruction to implement the mixing processing method of the speaker, the sound leakage elimination solution for the speaker can be applied to all types of electronic devices, improving the generality and practicability of the speaker sound leakage elimination solution.

[0183] Further, in another possible implementation manner of the present application, the above - mentioned first mixing unit is specifically configured to:

[0184] Determine the audio stream type corresponding to the audio to be played when the audio path configuration parameters contain a preset string;

[0185] Send a speaker mixing instruction to the DSP chip when the audio stream type corresponding to the audio to be played is a preset audio stream type, so that the DSP chip mixes the left - channel audio to be played and the right - channel audio to be played according to the speaker mixing instruction to generate the mixed audio to be played.

[0186] Thus, since the audio streams that need to be played simultaneously in the speaker and the earphone are usually several specific types of audio streams, such as incoming call ringtones, alarm clock ringtones, etc., it is possible to switch the data routing corresponding to the first speaker from the default audio path to the audio path corresponding to the second speaker when it is determined that the audio stream type corresponding to the audio to be played is a preset audio stream type, and perform mixing processing on the audio data of the left and right channels, so as to further improve the accuracy of leaky sound scenario discrimination, prevent mixing in unnecessary scenarios, affect the stability of audio playback, and waste computing power, thereby further improving the accuracy and reliability of speaker leaky sound cancellation, reducing the power consumption of the electronic device, and further enhancing the user experience.
