[0003] In practical applications, the wearing position of the headphones can be manually adjusted according to the user's ear shape and wearing habits to make the audio playback more suitable for the user's requirements. However, because the user manually adjusts the wearing position to adjust the audio, the audio adjustment effect is relatively poor. Summary of the Invention

[0005] In a first aspect, embodiments of this disclosure provide an audio adjustment method applied to a terminal device, comprising:

[0012] Based on the first distance collected by each distance sensor, the first audio is adjusted to obtain the target audio.

[0013] Thirdly, embodiments of this disclosure provide an audio adjustment device, which is disposed in a terminal device or headphones, the device comprising:

[0014] The first acquisition module is used to acquire a first distance collected by each distance sensor, wherein the distance sensor is installed in the earphone, and the first distance is the distance between the distance sensor and the target position of the human ear, wherein the target position is determined based on the first position of the distance sensor in the earphone.

[0015] The second acquisition module is used to acquire the first audio currently being played by the headphones;

[0016] The first processing module is used to adjust the first audio based on the first distance collected by each distance sensor to obtain the target audio.

[0017] Fourthly, embodiments of this disclosure provide a terminal device, including: at least one processor and a memory;

[0020] Fifthly, embodiments of this disclosure provide an earphone, including: at least one processor and a memory;

[0021] The memory stores computer-executed instructions;

[0022] The at least one processor executes computer execution instructions stored in the memory, causing the at least one processor to perform the audio adjustment method as described in the second aspect above and various possible designs of the second aspect.

[0023] In a sixth aspect, embodiments of this disclosure provide a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, implement the audio adjustment method as described in the first aspect and various possible designs of the first aspect, or the second aspect and various possible designs of the second aspect.

[0025] The audio adjustment method, apparatus, terminal device, and headphones provided in this embodiment include at least one distance sensor in the headphones. The system can acquire a first distance collected by each distance sensor in the headphones, as well as the first audio currently being played by the headphones. The first distance is the distance between the distance sensor and a target position of the user's ear. Based on the first distance collected by each distance sensor, the first audio is adjusted to obtain the target audio. In this process, since the target position is a feature point corresponding to the user's ear when wearing the headphones, and this feature point is a key location affecting the audio effect heard by the user, adjusting the audio based on the first distance obtained from the target position allows for more accurate audio adjustment. This avoids the need for the user to manually adjust the wearing position of the headphones to adjust the audio, thus improving the audio adjustment effect. Attached Figure Description

[0038] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0040] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0041] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0042] To facilitate understanding, the following will be combined with... Figure 1 The application scenarios applicable to the embodiments of this disclosure are described below.

[0043] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this disclosure. Please refer to [link / reference]. Figure 1The system includes a terminal device 101 and earphones 102. Terminal device 101 can be a mobile phone, tablet computer, etc. Earphones 102 can be open-back headphones. After establishing a Bluetooth connection between terminal device 101 and earphones 102, terminal device 101 can send a first audio file to be played to earphones 102. Upon receiving the first audio file, earphones 102 will play it. The first audio file can be adjusted during playback.

[0044] In practical applications, the wearing position of the headphones can be manually adjusted according to the user's ear shape and wearing habits to make the audio playback more suitable for the user's requirements. However, because the user manually adjusts the wearing position to adjust the audio, the audio adjustment effect is relatively poor.

[0045] In this embodiment, the earphone is equipped with at least one distance sensor. It can acquire a first distance collected by each distance sensor and a first audio signal currently being played. The first distance is the distance between the distance sensor and a target position of the user's ear. Based on the first distance collected by each distance sensor, the first audio signal is adjusted to obtain the target audio signal. In this process, since the target position is a feature point corresponding to the user's ear when wearing the earphone, and this feature point is a key location affecting the audio effect heard by the user, adjusting the audio based on the first distance obtained from the target position allows for more accurate audio adjustment. This avoids the need for the user to manually adjust the earphone's wearing position to adjust the audio, thus improving the effectiveness of audio adjustment.

[0046] The method disclosed herein will now be described through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0047] Figure 2 This is a schematic flowchart illustrating an audio adjustment method provided in an embodiment of this disclosure. Please refer to [link / reference]. Figure 2 The method may include:

[0048] S201. Obtain the first distance collected by each distance sensor.

[0049] The execution entity of this disclosure can be a terminal device or headphones, or an audio adjustment device installed in a terminal device or headphones. The audio adjustment device can be implemented through software or a combination of software and hardware. The terminal device can be a mobile phone, tablet computer, computer, etc. The headphones can be open-back headphones.

[0050] If the executing entity is a terminal device, then the terminal device needs to establish a connection with the headset to enable data transmission between them. For example, the terminal device and headset can establish a Bluetooth connection, a wireless network connection, etc. The terminal device can control the headset through an application configured on the terminal device.

[0051] A distance sensor is installed in the earphone. The first distance is the distance between the distance sensor and the target position of the ear. The target position is determined based on the first position of the distance sensor in the earphone.

[0052] Distance sensors can be capacitive sensors based on capacitance characteristics, optics, acoustics, etc. Other types include proximity sensors, time-of-flight sensors, and ultrasonic sensors. Preferably, the distance sensor can be a matrix type.

[0053] Below, in conjunction with Figure 3 The process of setting up the distance sensor will be explained. Figure 3 This is a schematic diagram illustrating the process of setting up at least one distance sensor according to an embodiment of this application. Please refer to... Figure 3 This includes earphone 301. Earphone 301 has three proximity sensors: proximity sensor 1, proximity sensor 2, and proximity sensor 3. Proximity sensor 1 is located at position 1, proximity sensor 2 at position 2, and proximity sensor 3 at position 3.

[0054] When the headphones are worn on the auricle, distance sensor 1 is at position 1, which can be positioned relative to the concha. Therefore, the target position of the ear corresponding to distance sensor 1 is the concha. The first distance collected by distance sensor 1 can be the distance between position 1 and the plane of the ear canal. Distance sensor 2 is at position 2, and the target position of the ear corresponding to distance sensor 2 is the facial area near the front of the helix. The first distance collected by distance sensor 2 can be the distance between position 2 and the facial area near the front of the helix. Based on the first distance collected by distance sensor 2, the relative position of the headphone's ear hook to the helix angle or other ear features can be determined, assessing headphone wearing and interference. Distance sensor 3 is at position 3, and the target position of the ear corresponding to distance sensor 3 is the ear canal entrance. The first distance collected by distance sensor 3 can be the distance between position 3 and the ear canal entrance. Based on the first distance collected by distance sensor 3, adjustment parameters (e.g., gain, equalizer parameters, spatial audio parameters, etc.) can be determined.

[0055] Optionally, position 1 can also be set relative to the helix. Therefore, the target position of the ear corresponding to distance sensor 1 is the helix position. The first distance acquired by distance sensor 1 can be the distance between position 1 and the helix.

[0056] It should be noted that the number of proximity sensors, the initial position of each proximity sensor, and the target position corresponding to each proximity sensor can be determined based on the shape, parameters, and usage scenario of the headphones. This application does not impose any restrictions.

[0057] If the executing entity is the headset, the headset can directly acquire the first distance collected by each distance sensor. If the executing entity is the terminal device, the headset acquires the first distance collected by each distance sensor and then sends the first distance collected by each distance sensor to the terminal device.

[0058] S202, Get the first audio currently playing on the headphones.

[0059] Users can specify the first audio in the terminal device so that the terminal device or headphones can acquire the first audio.

[0060] Below, in conjunction with Figure 4 This section explains the process of obtaining the first audio currently playing from the headphones. Figure 4 This is a schematic diagram illustrating the process of obtaining the first audio currently being played by the headphones, as provided in an embodiment of this application. Please refer to... Figure 4 This includes interfaces 401 to 402. Interfaces 401 and 402 can be pages provided by the terminal device. Referring to interface 401, when the user swipes down on the main page of the terminal device, the terminal device responds by displaying a drop-down control page. The user then clicks the Bluetooth icon on the drop-down control page. In response to this click, the terminal device activates Bluetooth and establishes a Bluetooth connection with the headset.

[0061] Please refer to interface 402. The user clicks the play icon corresponding to song 1 in the drop-down control page. The terminal device responds to the user's click operation and begins to control the headphones to play the first audio song 1. At this time, if the executing entity is the terminal device, the terminal device can directly obtain the first audio song 1. If the executing entity is the headphones, after the terminal device determines that the first audio is song 1, it sends the first audio song 1 to the headphones so that the headphones can obtain the currently playing first audio.

[0062] S203. Based on the first distance collected by each distance sensor, adjust and process the first audio to obtain the target audio.

[0063] The first audio can be adjusted based on the first distance collected by each distance sensor in the following ways: adjusting the volume of the first audio to obtain a target volume; and / or adjusting the sound quality of the first audio to obtain a target sound quality.

[0064] Adjusting the volume of the first audio audio includes increasing or decreasing the volume of the first audio audio; and / or adjusting the sound quality of the first audio audio includes adjusting the frequency response of the first audio audio and at least one of the frequency response-related parameters.

[0065] Frequency response, and frequency response-related parameters, include at least one of the following: equalizer parameters, dynamic equalizer parameters, signal compression and enhancement, delay, spatial object information, low-frequency enhancement and regeneration, or signal amplitude limiting.

[0066] The position of the headphones relative to the human ear can be determined based on the first distance collected by each distance sensor, thereby adjusting and processing the first audio.

[0067] For example, if the headphones are determined to be close to the ear based on the first distance collected by each distance sensor, the volume of the first audio audio can be decreased when adjusting the volume. Conversely, if the headphones are determined to be far from the ear based on the first distance collected by each distance sensor, the volume of the first audio audio can be increased when adjusting the volume.

[0068] The audio adjustment method provided in this disclosure acquires a first distance collected by each distance sensor. It also acquires the first audio currently playing through the headphones. Based on the first distance collected by each distance sensor, the first audio is adjusted to obtain a target audio. In this process, since the target position is a feature point corresponding to the user's ear when wearing the headphones, and these feature points are key locations affecting the audio's sound quality, adjusting the audio based on the first distance obtained from the target position allows for more accurate audio adjustment. This avoids the need for the user to manually adjust the headphone's wearing position to adjust the audio, thus improving the audio adjustment effect.

[0069] Based on any of the above embodiments, the following, in conjunction with Figure 5 The audio adjustment process (S203) is explained in detail.

[0070] Figure 5 This is a flowchart illustrating another audio adjustment method provided in an embodiment of this disclosure. Please refer to... Figure 5 The method includes:

[0071] S501. Determine the wearing status of the headphones based on the first distance collected by each distance sensor.

[0072] The wearing status of the headphones can be determined based on the first distance collected by each distance sensor in the following manner: if the first distance collected by at least one of the distance sensors is greater than a preset distance, the wearing status of the headphones is determined to be an unworn status; otherwise, the wearing status of the headphones is determined to be a worn status.

[0073] The preset distance can be determined based on ergonomic wearing comfort simulations and adjustments made based on actual product wearing conditions. The preset distance can be set in advance and stored in the preset storage space of the terminal device or headphones.

[0074] For example, assuming the headphones are as described above Figure 3 The earphone 301 shown contains distance sensor 1, distance sensor 2, and distance sensor 3. Distance sensor 1 is located at position 1, distance sensor 2 at position 2, and distance sensor 3 at position 3. The preset distance is 8mm. The specific acquisition of the first distance from each distance sensor is shown in Table 1.

[0075] Table 1

[0076] Distance sensor First distance Distance sensor 1 1mm Distance sensor 2 2mm Distance sensor 3 0.8mm

[0077] As shown in Table 1, it can be determined that the first distance collected by each distance sensor is less than the preset distance of 8mm. Therefore, it can be determined that the headphones are being worn.

[0078] S502. If the wearing status is "worn", determine the adjustment parameters based on the first distance collected by each distance sensor.

[0079] Adjustment parameters include preset volume and / or at least one preset gain.

[0080] If the first audio is adjusted based on the first distance collected by each distance sensor, including adjusting the volume of the first audio, to obtain the target volume, then the adjustment parameters include the preset volume.

[0081] If the first audio is adjusted based on the first distance collected by each distance sensor, including adjusting the sound quality of the first audio to obtain the target sound quality, then the adjustment parameters include at least one preset gain.

[0082] If the first audio is adjusted based on the first distance collected by each distance sensor, including adjusting the volume and sound quality of the first audio, then the adjustment parameters include a preset volume and at least one preset gain.

[0083] When adjusting the sound quality, each sound quality corresponds to a preset gain parameter, or at least one sound quality corresponds to a preset gain parameter. This application does not impose any limitations.

[0084] For example, the parameters for adjusting the first audio quality include the frequency response, equalizer parameters, and delay of the first audio. Then at least one preset gain includes the preset gain corresponding to the frequency response, the preset gain corresponding to the equalizer parameters, and the preset gain corresponding to the delay. Alternatively, the preset gain can be the preset gain corresponding to the frequency response, equalizer parameters, and delay of the first audio.

[0085] The target distance can be obtained by processing the first distance collected by each distance sensor using a first preset algorithm. Adjustment parameters are then determined based on the target distance.

[0086] At least one distance range and corresponding adjustment parameters for each distance range can be preset. The preset storage space of the terminal device or headphones can then be stored for these parameters.

[0087] After adjusting the first audio file, a target volume and / or target audio quality are obtained. The volume of the target audio file is determined as the target volume, and / or the audio quality of the target audio file is determined as the target audio quality.

[0088] For example, by processing at least one of the first distances shown in Table 1 above using a preset algorithm, a target distance of 5mm is obtained. The distance range corresponding to 5mm is obtained from the preset storage space as 4mm to 6mm, and the adjustment parameter corresponding to 4mm to 6mm is obtained as adjustment parameter 2. Adjustment parameter 2 includes preset volume 2, preset gain A2 corresponding to frequency response, preset gain B2 corresponding to equalizer parameters, and preset gain C2 corresponding to delay.

[0089] S503. Adjust the first audio according to the adjustment parameters to obtain the target audio.

[0090] For example, as illustrated above, adjustment parameter 2 includes preset volume 2, preset gain A2 corresponding to frequency response, preset gain B2 corresponding to equalizer parameters, and preset gain C2 corresponding to delay. Assuming the first audio is audio 1, adjusting audio 1 includes the following three scenarios:

[0091] Case 1: Adjust the volume of the first audio file. Determine the current volume of audio 1. If the current volume of audio 1 is the preset volume 2, then determine audio 1 as the target audio. If the current volume of audio 1 is not the preset volume 2, then adjust the current volume of audio 1 to the preset volume 2, and determine audio 1 as the target audio, while setting the current volume of audio 1 to the preset volume 2.

[0092] Scenario 2: Adjust the sound quality of the first audio file. Based on the preset gain A2 corresponding to the frequency response, adjust the frequency response of audio 1 to obtain the target frequency response. Based on the preset gain B2 corresponding to the equalizer parameters, adjust the equalizer of audio 1 to obtain the target equalizer. Based on the preset gain C2 corresponding to the delay, adjust audio 1 to obtain the target noise reduction. The target audio file is determined to be audio 1, which includes the target frequency response, target equalizer, and target delay.

[0093] Case 3: Adjust the volume and sound quality of the first audio file. Perform Case 1 and Case 2 processing on audio 1 respectively to obtain the target volume and target sound quality. The target audio file is determined to be audio 1, and the current volume of audio 1 is the preset volume 2. Audio 1 includes the target frequency response, target equalizer, and target delay.

[0094] S504. If the headphones are equipped with an inertial sensor, then acquire the inertial measurement parameters collected by the inertial sensor.

[0095] Inertial sensors can be accelerometers, gyroscopes, etc.

[0096] If the executing entity is the headset, the headset can directly acquire the inertial measurement parameters collected by the inertial sensor. If the executing entity is the terminal device, the headset, after acquiring the inertial measurement parameters collected by the inertial sensor, sends the inertial measurement parameters collected by the inertial sensor to the terminal device.

[0097] S505. Determine the current motion state of the user wearing the headphones based on inertial measurement parameters.

[0098] The current motion state can be a stationary state, a walking state, a running state, etc.

[0099] If the inertial sensor is an accelerometer, then the inertial measurement parameter can be at least one acceleration. Based on the magnitude of at least one acceleration, the current motion state of the user wearing the headphones is determined.

[0100] S506. Based on the current motion state of the user wearing the headphones and the first distance corresponding to each distance sensor, the first audio is adjusted and processed to obtain the target audio.

[0101] The system can weight the current motion state of the user wearing the headphones and the first distance corresponding to each distance sensor to obtain the target distance. Based on the target distance, adjustment parameters are determined, thereby adjusting the first audio signal.

[0102] It should be noted that the process of adjusting the first audio can be found in S502 to S503, and will not be repeated here.

[0103] The first audio is adjusted based on the user's current movement state and the first distance corresponding to each proximity sensor. This adjustment improves the flexibility and effectiveness of audio adjustment.

[0104] S507. If a three-dimensional model corresponding to the human ear is stored, the first audio is adjusted and processed according to the three-dimensional model corresponding to the human ear to obtain the target audio.

[0105] If the executing entity is a terminal device, the terminal device can acquire a first image, which includes an image of a human ear collected by the terminal device and an image of the position of the earphone at the human ear; process the first distance and the first image collected by each distance sensor to obtain a three-dimensional model corresponding to the human ear; and adjust the first audio according to the three-dimensional model corresponding to the human ear to obtain the target audio.

[0106] If the executing entity is an earphone, the earphone can send the first distance collected by each distance sensor to the terminal device, so that the terminal device can obtain a three-dimensional model corresponding to the human ear based on the first distance and the first image, where the first image is the human ear image collected by the terminal device; receive the three-dimensional model corresponding to the human ear sent by the terminal device; and adjust the first audio according to the three-dimensional model corresponding to the human ear to obtain the target audio.

[0107] A second preset algorithm can be used to process the first distance and the first image acquired by each distance sensor to obtain a three-dimensional model corresponding to the human ear. The three-dimensional model may also include relevant feature information corresponding to the user's head.

[0108] The 3D model more clearly indicates the distance between various feature points in the human ear and the headphones. Using the 3D model, adjustment parameters can be determined more accurately, improving the accuracy of audio adjustments.

[0109] It should be noted that the process of adjusting the first audio can be found in S502 to S503, and will not be repeated here.

[0110] After receiving the target audio, if the executing entity is a terminal device, the terminal device can send the target audio to the headphones, causing the headphones to play the target audio through the speakers. If the executing entity is the headphones, the headphones can directly play the target audio through the speakers.

[0111] At least one sensor can be installed in the earphone. Based on any of the above embodiments, the following will be combined with... Figure 6 The structure of the headphones will be explained. Figure 6 This is a schematic diagram of the structure of the earphone provided in an embodiment of this application. Please refer to... Figure 6The system includes a headset 601. The headset 601 comprises a main controller, battery, antenna module, RF module, microphone array, speaker, control buttons, distance sensor, and inertial sensor (optional). The main controller is a wireless system-on-chip (SOC) module, and the battery powers the entire system. The antenna module wirelessly connects to the terminal device or other devices via the RF module, transmitting the user's voice call signals collected by the microphone array to the mobile phone. The speaker plays the received voice signals. The control buttons are used for user input, enabling functions such as playback, volume adjustment, and answering calls. The distance sensor collects the first distance. The system can integrate the first distance collected by the distance sensor and the user's current motion state collected and determined by the inertial sensor, and transmit this information to the main controller. The main controller can send the first distance collected by the distance sensor and the user's current motion state collected and determined by the inertial sensor to the terminal device or cloud server to complete sensor information fusion, thereby performing operations such as 3D modeling, relative position analysis, and audio adjustment processing.

[0112] The audio adjustment method provided in this disclosure adjusts a first audio signal based on a first distance collected by each distance sensor to obtain a target audio signal. If the headphones are equipped with an inertial sensor, the first audio signal can also be adjusted based on the first distance collected by each distance sensor and inertial measurement parameters to obtain the target audio signal. If a three-dimensional model corresponding to a human ear is stored, the first audio signal can be adjusted based on the three-dimensional model to obtain the target audio signal. In the above process, audio adjustment can be performed based on the first distance obtained from the target position, allowing for more accurate audio adjustment. This avoids the need for users to manually adjust the wearing position of the headphones to adjust the audio, improving the audio adjustment effect. Furthermore, the first audio signal can be adjusted based on inertial measurement parameters and / or the three-dimensional model corresponding to the human ear. Further, adjusting the first audio signal based on the user's current state and a more accurate three-dimensional model improves the flexibility and accuracy of audio adjustment.

[0113] Based on any of the above embodiments, the following, in conjunction with Figure 7 The process of audio adjustment will be illustrated with an example.

[0114] Figure 7 This is a schematic diagram illustrating the audio adjustment process provided in an embodiment of this disclosure. Please refer to [link / reference]. Figure 7The system includes a terminal device 701 and an earphone 702. The terminal device 701 can be a mobile phone, tablet computer, computer, etc. The earphone 702 can be an open-back headset, equipped with three distance sensors and an inertial sensor. After the terminal device 701 and the earphone 702 establish a connection, the terminal device 701 can control the earphone 702 to play audio 2 via an application. At this time, the earphone 702 can acquire the first distance collected by each distance sensor and the inertial measurement parameters collected by the inertial sensor, and send these parameters to the terminal device 701.

[0115] After receiving the first distance collected by each distance sensor and the inertial measurement parameters collected by the inertial sensor, the terminal device 701 retrieves a preset distance from the preset storage space. It determines that the first distance collected by each distance sensor is less than the preset distance. Therefore, the terminal device 701 determines that the headphones are being worn. The terminal device 701 performs weighted processing on the current motion state of the headphone user and the first distance corresponding to each distance sensor, obtaining a target distance of 3mm. The terminal device 701 determines the distance range within the preset storage space and determines the corresponding adjustment parameters for this distance range, including a preset volume of 45, a preset gain of 0.2 for the equalizer parameters, a preset gain of 0.35 for the delay, and a preset gain of 1.2 for the signal amplitude limit.

[0116] Terminal device 701 determines that adjusting audio 2 includes adjusting its volume and sound quality. Therefore, terminal device 701 determines that the current volume of audio 2 is 30, and adjusts it to 45. Terminal device 701 then adjusts the frequency response of audio 2 according to a preset gain of 0.2 to obtain the target frequency response. According to a preset gain of 0.35 for the equalizer parameters, it adjusts the equalizer parameters of audio 2 to obtain the target equalizer parameters. According to a preset gain of 1.2 for the delay, it adjusts the delay to obtain the target delay. According to a preset gain of 1.2 for the signal amplitude limit, it adjusts the signal amplitude of audio 2 to obtain the target signal amplitude. The target audio is determined to be audio 2, with a target volume of 45. Audio 2 includes the target frequency response, target equalizer parameters, target delay, and target signal amplitude. After determining the target audio, terminal device 701 sends the target audio to headphones 702. Headphones 702 can play the target audio through their speakers.

[0117] The audio adjustment process provided in this disclosure involves acquiring a first distance from each distance sensor, and obtaining the first audio currently being played by the headphones. Based on the first distance acquired by each distance sensor, the first audio is adjusted to obtain the target audio. In this process, since the target position is a feature point corresponding to the user's ear when wearing the headphones, and these feature points are key locations affecting the audio's quality when played, adjusting the audio based on the first distance obtained from the target position allows for more accurate audio adjustment. This avoids the need for the user to manually adjust the headphone's wearing position to adjust the audio, thus improving the audio adjustment effect. Furthermore, the first audio can be adjusted based on inertial measurement parameters and / or a three-dimensional model corresponding to the human ear. Further adjustments based on the user's current state and a more accurate three-dimensional model enhance the flexibility and accuracy of audio adjustment.
