[0020] The purpose, features and advantages of the embodiments of the present application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0021] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the embodiments of the present application and are not intended to limit the embodiments of the present application.

[0022] In order to better understand the technical solutions of the embodiments of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Traditional dynamic speakers have poor sound quality in the mid- and high-frequency ranges, prone to prominent sibilance, high-frequency tremolo distortion, etc. However, wearable audio devices such as AR / VR currently use these speakers, leading to the current technical problem of poor sound quality in wearable audio devices.

[0024] Therefore, the embodiment of the present application provides a control method for a wearable audio device, in which at least two types of speakers are set on the wearable audio device, namely dynamic speakers and MEMS speakers, so that the wearable audio device can have good sound quality in the entire frequency band. Specifically, the embodiment of the present application can determine the target playback speaker among the dynamic speakers and MEMS speakers based on the detected usage scenario, thereby facilitating the determination of the target playback speaker suitable for the usage scenario, so as to ensure the audio playback quality of the wearable audio device in the usage scenario. Furthermore, when the target playback speaker is a MEMS speaker, the MEMS speaker will be controlled to align with the preset listening position of the user wearing the wearable audio device. Since the MEMS speaker can align with the preset listening position of the user, the MEMS speaker can directly align with the preset listening position to play the target audio, thereby reducing the loss of audio transmission, thereby achieving improved sound quality, and solving the technical problem of poor sound quality of wearable audio devices.

[0025] Based on this, the embodiment of the present application provides a control method for a wearable audio device, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a control method for a wearable audio device according to an embodiment of the present application. The wearable audio device is provided with a dynamic speaker and an adjustable audio module, wherein the adjustable audio module includes a MEMS speaker. The control method for the wearable audio device includes steps S10 to S30: Step S10, detecting a usage scenario of the wearable audio device; The wearable audio device in the embodiments of the present application may include but is not limited to wearable audio devices such as head-mounted display devices, smart watches, smart bracelets, headphones, mobile phones, digital broadcast receivers, PDAs (Personal Digital Assistants), PMPs (Portable Media Players), and the like.

[0026] Among them, the head-mounted display device includes but is not limited to mixed reality (Mixed Reality) - MR devices (such as MR glasses or MR helmets), augmented reality (Augmented Reality) - AR devices (such as AR glasses or AR helmets), virtual reality (Virtual Reality) - VR devices (such as VR glasses or VR helmets), extended reality (Extended Reality) - XR devices or some combination thereof and other head-mounted display devices.

[0027] It's important to note that MEMS speakers are ultra-thin (just 1mm thick), making them easy to integrate into space-critical devices, such as wearable audio devices like ultra-thin TWS (True Wireless Stereo) earphones. MEMS speakers also excel at high-frequency performance, with a frequency range up to 40kHz and a distortion rate below 1%, accurately reproducing treble details. MEMS speakers also offer high integration density and excellent resistance to vibration, pressure, and dust.

[0028] In the wearable audio device of this embodiment, at least two types of speakers are provided, namely dynamic speakers and MEMS speakers. The posture of the MEMS speakers can be adjusted. The posture of the MEMS speakers includes position and angle. The adjustable audio module can be provided next to the dynamic speaker. For example, the adjustable audio module can be provided above, below, left or right of the dynamic speaker. This embodiment does not make any specific limitation on this.

[0029] The wearable audio device may be an audio device for AR or VR, etc., which is not specifically limited in this embodiment. The adjustable audio module is movable, for example, the adjustable audio module can rotate and extend, etc., which is not specifically limited in this embodiment.

[0030] The usage scenario can be determined by the current process and / or running service in the wearable audio device. Exemplarily, the current process and / or running service in the wearable audio device can be obtained, and the usage scenario corresponding to the current process can be obtained, or the usage scenario corresponding to the running service can be obtained, or the usage scenario corresponding to both the running service and the current process can be obtained. For example, the mapping relationship between the running service and the usage scenario can be predetermined, and the mapping relationship between the process and the usage scenario can also be predetermined, thereby facilitating the determination of the usage scenario through the process and / or service. In other embodiments, the display screen of the wearable audio device can be captured, and the usage scenario of the wearable audio device can be detected through the display screen. The components in use in the wearable audio device can also be detected to determine the corresponding usage scenario through the components in use. For example, the mapping relationship between the usage scenario and the components can be predetermined. This embodiment does not specifically limit this.

[0031] Step S20, determining a target playback speaker among the dynamic speakers and MEMS speakers based on the usage scenario; It should be noted that different usage scenarios correspond to different target playback speakers, and the target playback speaker can be determined by the type of usage scenario. The target playback speaker is the speaker that plays the audio instructed by the user.

[0032] Exemplarily, according to the type of usage scenario, a target playback speaker is determined among a dynamic speaker and a MEMS speaker.

[0033] In a feasible embodiment, step S20 further includes steps S21 and S22: Step S21, when the usage scenario is of normal sound quality, determining that the target playback speaker is a dynamic speaker; Step S22 : When the usage scenario is a sound quality improvement scenario, determining that the target playback speaker is a MEMS speaker.

[0034] It should be noted that the normal sound quality type indicates that the sound quality played by the dynamic speaker has no obvious defects, for example, no abnormal distortion or frequency response deviation, etc. The improved sound quality type indicates that the sound quality of the usage scenario needs to be improved.

[0035] For example, the type of usage scenarios such as daily calls, conversations, and translations can be of the normal sound quality type, while the type of usage scenarios with high sound requirements such as music and games can be of the improved sound quality type. Usage scenarios belonging to the improved sound quality type and usage scenarios belonging to the normal sound quality type can be predetermined. In other embodiments, the type of the current usage scenario of the wearable audio device can be determined by responding to the user's sound quality instruction. For example, when the wearable audio device identifies a usage scenario with high sound quality requirements, a window can be automatically popped up to inquire whether to improve the sound quality. The wearable audio device can receive the sound quality improvement instruction triggered by the user in the window, and based on the sound quality improvement instruction, determine that the current usage scenario is of the improved sound quality type, and then directly determine that the target playback speaker is a MEMS speaker. If no sound quality improvement instruction is received, it can be determined that the current usage scenario is of the normal sound quality type.

[0036] In other embodiments, the user can also trigger a sound quality improvement command directly on the wearable audio device, without having to wait for the wearable audio device to pop up a window asking whether to perform sound quality improvement. In other embodiments, the type of usage scenario can be determined by the frequency band type of the audio being played. If the audio required to be played in the usage scenario falls within a preset low-frequency band, the usage scenario can be determined to be of normal sound quality, and the audio can be played through a dynamic speaker. If the audio required to be played in the usage scenario falls within a preset mid-high frequency band, the usage scenario can be determined to be of improved sound quality, and the audio can be played through a MEMS speaker. Dynamic speakers can play sounds between 100 and 8 kHz, while MEMS speakers can play sounds between 6 kHz and 40 kHz. Therefore, in this embodiment, configuring both dynamic and MEMS speakers on the wearable audio device can achieve a high-fidelity sound quality experience across the entire frequency band. Because the frequency band of audio that can be played by the dynamic speaker overlaps with the frequency band of audio that can be played by the MEMS speaker, to avoid mutual interference between the audio played by the two speakers in the overlapping audio frequency band, in this embodiment, a preset low-frequency band and a preset mid-high-frequency band can be determined. The preset low-frequency band and the preset mid-high-frequency band may not overlap. In other embodiments, a preset short interval of overlap may exist between the preset low-frequency band and the preset mid-high-frequency band. The preset short interval can be determined based on actual conditions so that the dynamic speaker and the MEMS speaker can switch naturally without sudden audio interruptions. In this embodiment, the dynamic speaker can be responsible for playing audio in the preset low-frequency band, and the MEMS speaker can be responsible for playing audio in the preset mid-high-frequency band. This can reduce interference between the sounds of the two speakers and improve the sound quality experience.

[0037] For example, when the target playback speaker is a dynamic speaker, the target audio can be played through the dynamic speaker. When the dynamic speaker plays the target audio, the MEMS speaker may not work, and the MEMS speaker may be shrunk. For example, the MEMS speaker may not be aligned with the user's preset listening position.

[0038] This embodiment determines the target playback speaker by using the scenario, thereby facilitating the selection of a suitable speaker for the usage scenario so that each usage scenario can have good sound quality. This is because the dynamic speaker has good sound quality in the low frequency band, but poor sound quality in the mid- and high-frequency bands, while the MEMS speaker has good sound quality in the mid- and high-frequency bands, but poor sound quality in the low frequency bands. Therefore, by determining the target playback speaker by using the scenario, it is easy to ensure good sound quality in each usage scenario.

[0039] Step S30: When the target playback speaker is a MEMS speaker, the MEMS speaker is controlled to align with a preset listening position of a user wearing the wearable audio device, and the target audio of the wearable audio device is played through the target playback speaker.

[0040] It should be noted that the preset listening position can be the user's ear hole. In other embodiments, the preset listening position can also be a position close to the user's ear hole. When the target playback speaker is a MEMS speaker, the MEMS speaker can be controlled to align with the preset listening position, thereby facilitating the improvement of sound quality. When the MEMS speaker is not working, the MEMS speaker can be in a retracted state. The retracted state refers to the state in which the adjustable audio module where the MEMS speaker is located is not extended. Therefore, when the target playback speaker is a MEMS speaker, it is necessary to adjust the posture of the MEMS speaker so that the MEMS speaker can align with the preset listening position in order to improve the playback sound quality. And because the preset listening positions of different users are different, and the MEMS speaker in this embodiment can be movable, it is convenient to control the MEMS speaker to align with the user's preset listening position, so that each user can have a good sound quality experience, solving the technical problem of poor sound quality of wearable devices.

[0041] Exemplarily, when the target playback speaker is a MEMS speaker, the MEMS speaker is controlled to align with the ear hole of the user wearing the wearable audio device, and the target audio of the wearable audio device is played through the target playback speaker.

[0042] In addition to a dynamic speaker, the wearable audio device of the embodiment of the present application is also provided with an adjustable audio module. The adjustable audio module includes a MEMS speaker. The MEMS speaker has better sound quality in the mid- and high-frequency ranges than the dynamic speaker, thereby ensuring that the wearable audio has good sound quality across the entire frequency band. Specifically, the embodiment of the present application can determine a target playback speaker between the dynamic speaker and the MEMS speaker based on the detected usage scenario, thereby facilitating the determination of a target playback speaker suitable for the usage scenario, so as to ensure the audio playback quality of the wearable audio device in the usage scenario. Furthermore, when the target playback speaker is a MEMS speaker, the MEMS speaker is controlled to align with the preset listening position of the user wearing the wearable audio device. Since the MEMS speaker can be aligned with the user's preset listening position, the MEMS speaker can directly align with the preset listening position to play the target audio, reducing the loss of audio transmission, thereby achieving improved sound quality and solving the technical problem of poor sound quality of wearable audio devices.

[0043] In a possible embodiment, please refer to Figure 2 The adjustable audio module includes a microphone, and step S30 further includes steps S31 to S33: Step S31, adjusting the posture of the MEMS speaker according to a preset adjustment path, and controlling the MEMS speaker to play a preset ultrasonic audio; It should be noted that the microphone included in the adjustable audio module can be an ultrasonic microphone that can collect ultrasonic waves. The adjustable audio module structure can be composed of a circuit board and a structural wall, on which both the ultrasonic microphone and the MEMS speaker can be mounted. The adjustable audio module can support telescopic rotation, thereby facilitating adjustment of the MEMS speaker's position and angle. The adjustable audio module can also be made ultra-thin.

[0044] The preset ultrasonic audio is a sound that the human body cannot hear, and the preset ultrasonic audio may be an audio frequency above 20 kHz. The preset adjustment path may be pre-set, for example, the preset adjustment path may be a pre-set path for the MEMS speaker to be screwed down to the ear hole. However, due to different ear hole positions of different users and different ways or postures of wearing the wearable audio device by different users, after adjusting the posture of the MEMS speaker according to the preset adjustment path, the MEMS speaker may not be fully aligned with the user's ear hole. Therefore, after adjusting the posture of the MEMS speaker according to the preset adjustment path, the posture of the MEMS speaker may still need to be adjusted.

[0045] In other embodiments, the position of the MEMS speaker may be adjusted directly according to a preset adjustment path, so as to align the MEMS speaker directly with the user's preset listening position.

[0046] For example, the position of the MEMS speaker is adjusted according to a preset adjustment path. After the position of the MEMS speaker is adjusted, the MEMS speaker can be controlled to play the preset ultrasonic audio. Alternatively, the position of the MEMS speaker can be adjusted according to the preset adjustment path while the MEMS speaker is controlled to play the preset ultrasonic audio. This embodiment does not make any specific restrictions on this.

[0047] Step S32, collecting the preset ultrasonic audio played by the MEMS speaker through the microphone to obtain the ultrasonic audio collected by the microphone; Step S33: Align the MEMS speaker with a preset listening position of a user wearing the wearable audio device based on the ultrasonic collected audio and the preset reference audio of the preset ultrasonic audio.

[0048] It should be noted that the ultrasonically captured audio is the audio played by the MEMS speaker, captured by the ultrasonic microphone. The preset reference audio is predetermined and can be the audio captured by the ultrasonic microphone when the MEMS speaker is aligned with the ear canal. This facilitates controlling the position of the MEMS speaker by comparing the ultrasonically captured audio with the preset reference audio, so as to align the MEMS speaker with the preset listening position. For example, the position of the MEMS speaker can be adjusted by controlling the expansion and contraction and rotation of the adjustable module.

[0049] For example, a microphone captures preset ultrasonic audio played by a MEMS speaker to obtain ultrasonic captured audio. Based on the comparison result of the ultrasonic captured audio with the preset reference audio, the adjustable audio module is controlled to align the MEMS speaker with the preset listening position of the user wearing the wearable audio device. For example, the adjustable audio module can be controlled to rotate and extend, etc., which is not specifically limited in this embodiment. The comparison result can be the audio similarity between the ultrasonic captured audio and the preset reference audio.

[0050] In a feasible embodiment, step S33 further includes steps S331 to S333: Step S331, comparing the ultrasonically collected audio with a preset reference audio to obtain audio similarity; Step S332: if the audio similarity is greater than or equal to a preset similarity threshold, determining that the MEMS speaker is aligned with a preset listening position of a user wearing the wearable audio device; Step S333 : When the audio similarity is less than the preset similarity threshold, adjust the position of the MEMS speaker until the audio similarity is greater than or equal to the preset similarity threshold.

[0051] It should be noted that audio similarity can represent the degree of similarity between the ultrasonically collected audio and the preset reference audio. The closer the MEMS speaker is to the ear canal, the higher the audio similarity. The preset similarity threshold can be set based on actual conditions and is not specifically limited in this embodiment.

[0052] When the audio similarity is greater than or equal to the preset similarity threshold, it indicates that the MEMS speaker is basically aligned with the ear hole, and thus it can be determined that the MEMS speaker is aligned with the preset listening position of the user wearing the wearable audio device.

[0053] If the audio similarity is less than a preset similarity threshold, it indicates that the MEMS speaker is not aligned with the ear canal, so the MEMS speaker position needs to be adjusted further, for example, by continuing to control the adjustable audio module to extend and / or rotate the MEMS speaker. For another example, the MEMS speaker position can be adjusted in a direction with higher audio similarity.

[0054] Exemplarily, a comparison reference audio of the ultrasonic collection audio can be obtained from the preset reference audio. The comparison reference audio has the same time period as the ultrasonic collection audio during the preset reference audio period. The similarity between the ultrasonic collection audio and the comparison reference audio is calculated to obtain the audio similarity. For example, the audio similarity can be calculated based on the audio waveform of the ultrasonic collection audio and the audio waveform of the comparison reference audio.

[0055] In other embodiments, when the MEMS speaker rotates downward according to a preset adjustment path, a preset ultrasonic audio can be played, and the microphone can collect audio during the downward rotation process to obtain collected audio, determine a collected audio waveform corresponding to the collected audio, determine a target reference audio of the collected audio in the preset reference audio, and then determine a reference audio waveform of the target reference audio. The similarity between the collected audio waveform and the reference audio waveform at each moment in the downward rotation process can be calculated. When the similarity at the last moment in the downward rotation process is greater than or equal to a preset similarity threshold, it can be determined that the MEMS speaker is aligned with the preset listening position of the user wearing the wearable audio device. When the similarity at the last moment in the downward rotation process is less than the preset similarity threshold, a similarity waveform in the downward rotation process can be constructed by calculating the similarity between the collected audio waveform and the reference audio waveform at each moment in the downward rotation process. The target similarity with the highest similarity can be determined in the similarity waveforms, and the target posture at the target moment where the target similarity is located can be obtained. The adjustable audio module can be controlled to move to the target position so as to quickly align with the ear hole. In other embodiments, a rising similarity interval of an upward trend can be determined in the similarity waveform, a first similarity with the lowest similarity and a second similarity with the highest similarity can be determined in the rising similarity interval, a first posture at the moment of the first similarity is obtained, a second posture at the moment of the second similarity is obtained, a target direction of the first posture pointing to the second posture is determined, and the adjustable audio module is controlled to move in the target direction so as to control the MEMS speaker to quickly align with the ear hole, the first posture includes a first position and a first angle, the second posture includes a second position and a second angle, and the target direction includes a first position direction from the first position to the second position, and a second angle direction from the first angle to the second angle.

[0056] This embodiment compares the ultrasonically collected audio with the preset reference audio, thereby facilitating the improvement of the accuracy of the MEMS speaker posture adjustment, thereby facilitating the improvement of the sound quality experience.

[0057] In a feasible embodiment, step S30 further includes steps A10 to A30: Step A10: obtaining a sound effect algorithm and obtaining the audio to be played by the wearable audio device, and optimizing the audio to be played by using the sound effect algorithm to obtain the target audio; It should be noted that the sound effect algorithm can optimize the sound quality, and the sound effect algorithm can characterize the equalizer parameters and filter parameters. Different sound effect algorithms have corresponding equalizer parameters and filter parameters. The audio to be played is the audio that needs to be played for the user to listen to. For example, it can be music played by the user's instructions, or game audio played in a game scene, etc. This embodiment does not make specific limitations. The audio to be played can be optimized by the sound effect algorithm to obtain the target audio. For example, the sound quality of the audio to be played can be optimized by the equalizer parameters and filter parameters in the sound effect algorithm, and then the target audio can be obtained.

[0058] In a feasible embodiment, step A10 further includes steps A11 to A13: Step A11: before the MEMS speaker plays the target audio, the preset place detection audio is played through the MEMS speaker, and the preset place detection audio played by the MEMS speaker is collected through the microphone to obtain the place collection audio; Step A12: determining a target spatial location for audio collection in a mapping relationship between preset collected audio and preset locations; Step A13: Determine the sound effect algorithm corresponding to the target space and the usage scenario.

[0059] It should be noted that the preset place detection audio is also ultrasonic, and the preset place detection audio can be an audio in the frequency band of 20Khz~40Khz. The preset place detection audio and the preset ultrasonic audio may be different. The microphone set in the adjustable audio module can collect the preset place detection audio played by the MEMS speaker to obtain the place collection audio. The audio features can be determined from the place collection audio. The audio features can be audio features used to reflect the spatial place. The target preset collection audio of the place collection audio is determined in the mapping relationship between the preset collection audio and the preset place through the audio features, and the preset place corresponding to the preset collection audio is used as the target spatial place of the place collection audio.

[0060] The multiple preset places may be small rooms, large rooms, outdoor places, etc., which is not specifically limited in this embodiment.

[0061] In this embodiment, a preset algorithm mapping relationship can be set. The preset algorithm mapping relationship includes preset sound effect algorithms corresponding to both preset locations and preset usage scenarios. In the preset algorithm mapping relationship, the sound effect algorithm corresponding to both the target space and the usage scenario can be determined. The preset algorithm mapping relationship can be set in advance based on actual conditions and is not specifically limited in this embodiment.

[0062] For example, before the MEMS speaker plays the target audio, a preset place detection audio can be played through the MEMS speaker. The preset place detection audio is a sound that cannot be heard by the human body. When the target playback speaker is a dynamic speaker, the preset place detection audio can be played directly through the MEMS speaker. When the target playback speaker is a MEMS speaker, the preset place detection audio can be played through the MEMS speaker before the MEMS speaker plays the target audio. The preset place detection audio played by the MEMS speaker is collected by a microphone to obtain place collection audio; the target space location of the place collection audio is determined in the mapping relationship between the preset collection audio and the preset place; and the sound effect algorithm corresponding to the target space location and the usage scenario is determined in the preset algorithm mapping relationship.

[0063] This embodiment determines the sound effect algorithm by jointly determining the target space and usage scenario, thereby facilitating providing users with a better sound quality experience and improving the sound quality of wearable audio devices.

[0064] Step A20: If the target playback speaker is a dynamic speaker, drive the dynamic speaker to play the target audio through a first audio amplifier connected to the dynamic speaker; Step A30 : When the target playback speaker is a MEMS speaker, a second audio amplifier connected to the MEMS speaker is used to drive the MEMS speaker to play the target audio.

[0065] It's important to note that because dynamic speakers and MEMS speakers operate differently, they require different PAs (power amplifiers). The first audio amplifier drives the dynamic speaker, while the second audio amplifier drives the MEMS speaker. Dynamic and MEMS speakers are connected to different PAs.

[0066] Exemplarily, when the target playback speaker is a dynamic speaker, the first audio amplifier drives the dynamic speaker to play the target audio. When the target playback speaker is a MEMS speaker, the second audio amplifier drives the dynamic speaker to play the target audio.

[0067] This embodiment drives different speakers through different PAs, thereby improving the reliability of audio playback of the wearable audio device.

[0068] In a possible embodiment, please refer to Figure 3 The control method of the wearable audio device further includes steps X10 to X30: Step X10: When the target playback speaker is a MEMS speaker and it is detected that the wearable audio device has a posture adjustment, obtaining an initial posture of the wearable audio device before the posture adjustment, and obtaining an adjusted posture of the wearable audio device after the posture adjustment; It should be noted that when the target playback speaker is a MEMS speaker, the MEMS speaker is aimed at the user's preset listening position. However, if the user adjusts the wearing method of the wearable audio device in the middle of the process, or takes off the wearable audio device in the middle of the process and puts on the wearable audio device again, the MEMS speaker may not be aimed at the preset listening position. Therefore, when the target playback speaker is a MEMS speaker and it is detected that the wearable audio device has a posture adjustment, it is necessary to adjust the position and angle of the MEMS speaker so that the MEMS speaker can be realigned with the preset listening position.

[0069] The initial posture is the posture of the wearable audio device before adjusting its posture. For example, after a user wears the wearable audio device and aligns the MEMS speaker with a preset listening position, the posture of the wearable audio device can be detected as the initial posture. Both the initial posture and the adjusted posture can be detected by the IMU (Inertial Measurement Unit) on the wearable audio device. The initial posture can be relative to the preset zero-position posture of the wearable audio device, and the adjusted posture can also be relative to the preset zero-position posture of the wearable audio device. The preset zero-position posture can be determined based on actual conditions and is not specifically limited in this embodiment.

[0070] After the wearable audio device is adjusted, the posture can be detected again to serve as the adjusted posture. The adjusted posture is the posture of the wearable audio device after the posture adjustment.

[0071] Step X20, determining the posture deviation between the initial posture and the adjusted posture; Step X30: When the posture deviation is greater than a preset deviation threshold, adjust the posture of the MEMS speaker according to the posture deviation.

[0072] It should be noted that the posture deviation is the difference between the adjusted posture and the initial posture. The posture deviation can be 0 or a value greater than 0. When the posture deviation is less than or equal to the preset deviation threshold, the posture of the MEMS speaker can remain unchanged. When the posture deviation is greater than the preset deviation threshold, the posture of the MEMS speaker is adjusted according to the posture deviation. The preset deviation threshold can be determined based on actual conditions, and this embodiment does not specifically limit this. The posture deviation includes the posture deviation of the wearable audio device and the position deviation of the wearable audio device.

[0073] The posture of the MEMS speaker can be compensated based on the posture deviation and position deviation, so that the MEMS speaker can be aligned with the preset listening position. Even if the posture of the wearable audio device is adjusted in the middle, the MEMS speaker can be guaranteed to be aligned with the preset listening position, thereby facilitating the continuous provision of good sound quality experience for users.

[0074] Exemplarily, when the posture deviation is greater than a preset deviation threshold, the rotation angle of the MEMS speaker is compensated by the posture deviation based on the posture deviation, and the position of the MEMS speaker is compensated by the position deviation to offset the posture deviation generated by the wearable audio device, so that the MEMS speaker is realigned with the preset listening position. For example, the posture of the MEMS speaker can be inversely transformed based on the posture deviation to align the MEMS speaker with the preset listening position. For example, if the posture deviation is that the wearable audio device moves to the left by acm and the wearable audio device rotates clockwise by b degrees, then the MEMS speaker should move to the right by acm and the MEMS speaker should rotate counterclockwise by b degrees, thereby facilitating the MEMS speaker to align with the preset listening position.
