Abstract
Description
Technical Field
[0001] This application relates to the field of headphone technology, and in particular to providing a headphone. Background Technology
[0002] Open-back headphones are headphones that are designed to not go inside the ear and do not block or cover the ears. Users can hear some external sounds, such as ambient noise and other people talking. This design allows users to enjoy music without completely isolating themselves from external sounds.
[0003] However, the microphones of existing open-back headphones are all located on the main body of the headphones. When the user is in a windy environment, the wind blows directly over the microphone, which will cause obvious wind noise. In addition, because the microphone is close to the speaker inside the headphone body, the sound of the speaker is easily picked up by the microphone, resulting in echo and howling, thus affecting the user experience. Utility Model Content
[0004] The purpose of this application is to provide an earphone that addresses problems such as wind noise, echo, and howling in existing earphones.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] This application provides an earphone, including:
[0007] The earphone body contains a first microphone matrix.
[0008] The ear hook is connected to the main body of the earphone and is used to hang on the auricle. The ear hook is provided with a second microphone matrix, which is communicatively connected to the first microphone matrix to form a microphone array that works together.
[0009] Optionally, the first microphone matrix is located on the side of the earphone body away from the ear canal.
[0010] Optionally, the ear hook includes a first area, and the second microphone matrix is disposed within the first area;

[0014] The second region is the area from the highest point of the ear hook to the second end, facing away from the auricle.
[0015] Optionally, in the cross-sectional direction of the ear loop, the central angle of the first region ranges from 0° to 150°.
[0016] Optionally, the ear hook has a first end and a second end, the first end being connected to one side of the earphone body, and the second end being located on the other side away from the earphone body;
[0017] The first region includes the side of the ear hook and the bottom of the second end, and the second microphone matrix is disposed on the side of the ear hook and / or the bottom of the second end.
[0018] Optionally, the ear hook is a flexible component.
[0019] Optionally, the closest distance between the second microphone matrix and the first microphone matrix ranges from 15mm to 40mm.
[0020] Optionally, the first microphone matrix includes at least one first microphone, and / or the second microphone matrix includes at least one second microphone.

[0024] The beneficial effects of the headphones provided in this application are as follows: Compared with the prior art, this application, by placing the second microphone matrix on the ear hook and utilizing the shielding effect of the auricle, can selectively activate the first and / or second microphone matrices according to wind conditions, thereby effectively reducing the impact of wind noise and providing clearer call quality. Furthermore, by arranging the second microphone matrix on the ear hook, the increased distance between it and the speaker inside the headphone body, and the fact that it is not in the same cavity, can significantly reduce echo and feedback phenomena, allowing for higher gain settings and improving auxiliary hearing effects. Therefore, this application, through optimizing the microphone placement and intelligent switching mechanism, can effectively improve the user experience. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0040] In existing open-back headphones, the microphones are located on the main body of the headphones. When the user is in a windy environment, the wind blowing directly across the microphones causes noticeable wind noise, affecting call and audio experience. Furthermore, because the microphones are close to the speakers inside the headphones, the sound from the speakers is easily picked up by the microphones, resulting in echo and feedback phenomena. This is especially noticeable in auxiliary hearing functions, where the gain setting is too high, severely impacting the user experience.
[0041] To address the aforementioned technical problems, this application provides an earphone that optimizes sound pickup by distributing microphones in different parts of the earphone (earphone body and ear hook) and utilizing the physical characteristics of the auricle (blocking effect), thereby improving call quality, reducing echo and feedback, and effectively enhancing the user experience. The specific type of earphone in this application is not particularly limited; for example, it can be an open-back earphone, a sports earphone, etc.
[0042] In some embodiments, refer to Figure 1 and Figure 2 As shown, this application provides an earphone, including: an earphone body 1 and an ear hook 2. The earphone body 1 contains a first microphone matrix; the ear hook 2 is connected to the earphone body 1 and is used to hang on the auricle, and the ear hook 2 contains a second microphone matrix, which is communicatively connected to the first microphone matrix to form a microphone array operating collaboratively.
[0043] Specifically, the earphone body 1 has a built-in first microphone matrix, which includes at least one first microphone 3, and the earphone body 1 has a first pickup hole 5 that is connected to the first microphone 3, which is mainly responsible for sound collection during call function and active noise cancellation function.
[0044] The call function refers to the headset's ability to allow users to conduct voice communication. It can connect to devices such as mobile phones and computers via Bluetooth or other wireless technologies to make calls. For example, when a user makes a call, the ambient sound of their surroundings is also transmitted to the other party, making the call sound noisy. In this case, the headset controls the microphone to operate during the call, achieving noise reduction and making the call quality clear and natural.
[0045] Active noise cancellation is a technology that actively reduces ambient noise to provide a quieter listening environment. For example, when a user is listening to music in a noisy environment, ambient sounds will enter the headphones, resulting in poor sound quality. In this case, the user can actively control the microphone to achieve active noise cancellation, reduce ambient noise, and improve audio quality.
[0046] The ear hook 2 is designed with a second microphone matrix, which includes at least one second microphone 4. The ear hook 2 is provided with a second pickup hole 6 that corresponds to and communicates with the second microphone 4, for hearing assistance functions and for use during calls or noise reduction operations under specific conditions (such as headwinds). Because its position is close to the outside of the ear, it can effectively reduce the echo and howling problems caused by the speaker (not shown in the figure) inside the earphone body 1.
[0047] The hearing aid function is designed for people with hearing impairments or those who need to enhance their hearing experience, aiming to help them better perceive surrounding sounds. Since the hearing aid function typically requires a high gain setting, if the second microphone matrix for the hearing aid is located on the earphone body 1, its proximity to the speaker can easily cause echo and feedback problems, preventing the gain from being too high and thus failing to meet user needs. To avoid echo and feedback problems caused by the second microphone matrix picking up speaker sound due to excessive proximity, this application optimizes the microphone position by placing the second microphone matrix for hearing aid on the ear hook 2, away from the speaker.
[0048] When worn normally, the increased distance between the second microphone array and the speaker effectively improves sound isolation and reduces echo and feedback issues. In this case, the headphone gain can be increased to provide users with a better listening experience.
[0049] When a user touches or covers the earphones, a cavity is formed. If the second microphone matrix is located inside the earphone body 1, the speaker and the second microphone matrix are in the same cavity. The speaker volume is amplified by the cavity, and the sound is coupled into the second microphone matrix, easily causing echo and feedback problems. Therefore, this application places the second microphone matrix on the ear hook 2. Because the auricle separates the second microphone matrix on the ear hook 2 from the speaker, when the earphone body 1 is covered by the hand, the second microphone matrix and the speaker are not in the same cavity. The speaker sound amplified by the cavity is not directly transmitted to the second microphone matrix, thus effectively reducing echo and feedback problems.
[0050] The working principle of the headphones provided in the embodiments of this application is described below, which roughly includes:
[0051] Auxiliary hearing function: When the auxiliary hearing function is activated, only the second microphone matrix on the ear hook 2 is turned on. Because it is farther away from the speaker in the main body of the earphone 1 and is not in the same cavity, the risk of echo and feedback can be greatly reduced, and higher gain settings can be allowed to provide a better hearing assistance experience.
[0052] Call Function and Active Noise Cancellation: When the headset activates the call function and / or active noise cancellation, it detects wind conditions and coordinates the microphone operation accordingly. Specifically: In windless environments, both the first and second microphone matrices are activated simultaneously. These two microphone matrices work together to form a microphone array, which can capture sound information from multiple directions. This allows the headset to identify and process environmental noise from a wider range of angles, providing a more comprehensive and efficient noise cancellation effect. When the user walks against the wind, due to the obstruction of the ear, the wind is more likely to blow towards the first microphone matrix on the headset body 1. Therefore, the first microphone matrix on the headset body 1 detects more noise. In this case, the first microphone matrix on the headset body 1 is turned off, and the second microphone matrix on the ear hook 2 is used to reduce wind noise interference. When the user walks with the wind, due to the obstruction of the ear, the wind is more likely to blow towards the second microphone matrix on the ear hook 2. Therefore, the second microphone matrix on the ear hook 2 detects more wind noise. In this case, the second microphone matrix on the ear hook 2 is turned off, and the first microphone matrix on the headset body 1 is used instead, avoiding the performance degradation of the second microphone matrix on the ear hook 2 due to wind noise.
[0053] The microphones in the first and second microphone matrices of this application can be feedforward noise-canceling microphones, which together form a microphone array that can flexibly switch working modes under different environmental conditions to adapt to the user's needs, whether it is to improve call quality, enhance noise reduction effect or improve hearing aid experience.
[0054] Therefore, the headphones provided in this application, by optimizing the microphone layout and intelligent switching mechanism, can solve the problems of wind noise, echo and howling faced by traditional open-back headphones, and can effectively improve the user experience.
[0055] In some embodiments, refer to Figure 1 and Figure 2 As shown, the first microphone matrix is located on the side of the headphone body 1 away from the ear canal.
[0056] Specifically, the first microphone 3 in the first microphone matrix can be one or more, respectively located on one or more sides of the headphone body 1 away from the ear canal. The first pickup hole 5 is positioned corresponding to the first microphone 3, achieving an exposed design. This design is mainly to ensure that the first pickup hole 5 and the first microphone 3 are not blocked by the user's ears, head, or other parts, thereby improving the sound pickup effect. Understandably, if the first pickup hole 5 and the first microphone 3 are located close to the inner side of the ear canal, the user's auricle or other parts may easily block the first pickup hole 5 and the first microphone 3 when wearing the headphones, resulting in a decrease in sound pickup effect.
[0057] Therefore, by directly exposing the first microphone matrix to the outside air, this embodiment of the application can capture external sounds more directly, reducing sound wave attenuation or reflection caused by structural design. This allows the first microphone matrix to capture external sounds more directly, improving the sensitivity and accuracy of sound pickup. Furthermore, since the speaker inside the earphone body 1 is generally close to the ear canal, this application positions the first microphone matrix primarily towards the external environment, rather than towards the speaker inside the earphone body 1, maximizing the distance between them and further reducing unnecessary sound feedback, which is beneficial for improving sound pickup performance.
[0058] In some embodiments, refer to Figure 1 and Figure 2 As shown, the ear hook 2 has a first end 7 and a second end 8. The first end 7 is connected to one side of the headphone body 1, and the second end 8 is located on the other side away from the headphone body 1. The ear hook 2 is a curved structure that extends from the first end 7 to the second end 8. The curved structure is arranged around the headphone body 1, and there is a hanging space 9 between the curved structure and the headphone body 1 that is clamped on the auricle.
[0059] Specifically, the first end 7 of the ear hook 2 is connected to one side of the headphone body 1, while the second end 8 is located on the other side of the headphone body 1, forming a wraparound curved structure. The curved shape of the ear hook 2 can be ergonomically designed to adapt to the natural curve of the user's ear, and an appropriate hanging space 9 is left between the ear hook 2 and the headphone body 1 so that the headphones do not press directly on the ear. This design not only improves wearing comfort but also enhances the stability of the headphones, preventing them from falling off during exercise.
[0060] Furthermore, the curved structure can be finely adjusted to suit different users' ear shapes, ensuring optimal wearing experience for each user. For example, the ear hook 2 is a flexible component, made of a soft and elastic material (such as silicone, TPU, or memory foam covering a metal or plastic frame). This provides sufficient support while maintaining flexibility, making it easy for users to put on and take off the headphones. By using adjustable ear hook 2, users can adjust the curvature of the ear hook 2 according to their needs, achieving a personalized fit and effectively improving the user experience.
[0061] Therefore, the ear hook 2 design of this embodiment can significantly improve the stability and comfort of wearing headphones.
[0062] In some embodiments, refer to Figure 3 As shown, the ear hook 2 includes a first region 10, and a second microphone matrix is disposed within the first region 10; wherein, the first region 10 is the area where the ear hook 2 does not contact the auricle or the surrounding parts of the auricle.
[0063] Specifically, the first region 10 refers to the part of the ear hook 2 that does not contact the auricle and its surrounding parts (such as the head), that is, the area that does not contact the user's skin. The number of second microphones 4 in the second microphone matrix can be one or more. When there are multiple second microphones 4, the multiple second microphones can be distributed at intervals within the first region 10.
[0064] Because the second microphone matrix is located in an area that does not contact the user's skin, it avoids obstruction from the auricle or other parts of the body, reducing sound attenuation or reflection caused by physical obstacles, thereby improving the clarity and sensitivity of sound acquisition. Furthermore, considering that the auricle can generate some reflected noise on the second microphone matrix, affecting sound pickup quality, placing the second microphone matrix in an area that does not contact the auricle can also reduce the impact of this reflected noise.
[0065] Therefore, by placing the second microphone matrix within the first region 10 of the ear hook 2, this application can significantly improve the sound pickup effect and effectively avoid the problems of noise obstruction and reflection.
[0066] In some embodiments, refer to Figure 3 As shown, in the cross-sectional direction of the ear loop 2, the central angle α of the first region 10 ranges from 0° to 150°.
[0067] Specifically, the ear hook 2 can be tubular in shape to accommodate the second microphone matrix and wiring. The first region 10 refers to the part of the ear hook 2 that does not contact the auricle and its surrounding area, and its central angle α ranges from greater than 0° to less than or equal to 150°. This means that within this angle range, the design of the ear hook 2 can ensure that the second microphone matrix is located in a position that is not obstructed by the auricle or skin.
[0068] This embodiment of the application ensures that the second microphone matrix is positioned optimally for sound pickup by limiting the central angle α of the first region 10 to within 150°. This angle range is sufficiently large to cover most external ambient sounds while avoiding interference from the auricle and other body parts, thereby significantly improving sound pickup performance.
[0069] In some embodiments, refer to Figure 4 and Figure 5 As shown, the ear hook 2 is arc-shaped and has a first end 7 and a second end 8. The first end 7 is connected to one side of the headphone body 1, and the second end 8 is located on the other side away from the headphone body 1. When the ear hook 2 is worn on the auricle, the ear hook 2 has a highest point P located between the first end 7 and the second end 8, and the first region 10 includes a second region 11, and the second microphone matrix is located in the second region 11. The second region 11 is the region from the highest point P of the ear hook 2 to the second end 8 and facing away from the auricle.
[0070] Specifically, the ear hook 2 has a distinct curved arc, which better conforms to the user's ear and provides stable support when worn, allowing the ear hook 2 to have a highest point P when worn on the ear. The second region 11 is the area from the highest point P of the ear hook 2 to the second end 8 and facing away from the ear, that is, the rear region of the ear hook 2. This region can be understood as the part of the ear hook 2 extending downward from the highest point P to the other side of the headphone body 1, and this part faces away from the ear and will not be obstructed by the ear or other parts.
[0071] The number of second microphones 4 in the second microphone matrix can be one or more. When there are multiple second microphones 4, they can be distributed at intervals along the length of the ear hook 2 in the second area 11 of the ear hook 2. The second pickup hole 6 is set corresponding to the second microphone 4. When the user wears the headphones, the second microphone 4 and the second pickup hole 6 are located behind the auricle, ensuring that they are not blocked by the auricle or other parts of the head. This allows for more direct capture of external sounds and reduces sound attenuation or reflection caused by physical obstacles, thereby improving the sound pickup effect.
[0072] Specifically, when the user is in a headwind environment, the rear area of the ear hook 2 (i.e., the second area 11) can provide some shielding, effectively preventing the airflow from directly impacting the second microphone matrix, thereby reducing the impact of wind noise. Even in a tailwind, the curved structure of the ear hook 2 can help guide airflow to some extent, which helps reduce the impact of wind noise on the second microphone matrix, thus maintaining high sound pickup quality.
[0073] Therefore, by placing the second microphone matrix in the rear area of the arc-shaped ear hook 2, this embodiment of the application not only significantly improves the sound pickup effect, but also effectively reduces the impact of wind noise and improves the overall performance of the headphones.
[0074] In some embodiments, refer to Figure 1 and Figure 2 As shown, the ear hook 2 has a first end 7 and a second end 8. The first end 7 is connected to one side of the headphone body 1, and the second end 8 is located on the other side away from the headphone body 1. The first region 10 includes the side of the ear hook 2 and the bottom of the second end 8. The second microphone matrix is located on the side of the ear hook 2 and / or the bottom of the second end 8.
[0075] Specifically, the second microphone 4 in the second microphone matrix can be one or more, and can be placed in different positions on the ear hook 2. When the second microphone 4 is placed on the side of the first area 10 of the ear hook 2, the second microphone 4 is located in an area that does not contact the user's skin, thus avoiding obstruction caused by the auricle or other parts, achieving efficient sound pickup. When the second microphone 4 is placed at the bottom of the second end 8 of the ear hook 2, this means that in addition to not contacting the user's skin, it is also located in a relatively concealed position on the ear hook 2. This position can be naturally shielded by the structure of the ear hook 2 itself, reducing the chance of wind directly impacting the second microphone 4. The second pickup hole 6 corresponding to the second microphone 4 is also located here, ensuring that the sound signal can be accurately transmitted to the second microphone 4. In this way, it is difficult for wind to blow directly onto the second microphone 4, thereby effectively reducing the impact of wind noise on audio input and improving call quality.
[0076] Understandably, the design of the bottom of ear hook 2 acts as a wind barrier, allowing the second microphone matrix to capture clearer sound signals even in windy environments. This reduces wind noise in the background, improving speech clarity and intelligibility, especially noticeable in outdoor or mobile settings. Furthermore, positioning the second microphone matrix at the bottom of ear hook 2 gives it directionality, better capturing sounds from specific directions (such as the user's voice) while blocking ambient noise from other directions.
[0077] Furthermore, placing the second microphone matrix at the bottom of the ear hook 2, maximizing its distance from the speaker inside the headphone body 1, increases the physical distance between them, which helps reduce echoes caused by sound wave reflections. The larger spacing also reduces the risk of feedback from the speaker due to the second microphone matrix receiving sound, which is especially important for applications requiring high gain.
[0078] In some embodiments, refer to Figure 2 As shown, all the second microphones 4 in the second microphone matrix are facing different directions.
[0079] Specifically, by using microphones facing different directions, the headphones can collect, compare, and process sound signals from different directions, effectively reducing or eliminating unwanted background noise. This allows the device to capture sound from all directions more accurately, thereby improving overall performance.
[0080] In some embodiments, the closest distance between the second microphone matrix and the first microphone matrix ranges from 15mm to 40mm.
[0081] Specifically, if the distance between the second microphone matrix and the first microphone matrix is too small, their pickup areas will overlap significantly, causing the picked-up sound signals to interfere with each other and making it impossible to effectively distinguish sounds from different directions. This affects noise reduction and speech clarity, leading to a decrease in audio input quality. Furthermore, an excessively small microphone spacing weakens their directional pickup capability, making it difficult to separate background noise from the user's voice, thus reducing call quality and the effectiveness of active noise cancellation.
[0082] If the distance between the second microphone matrix and the first microphone matrix is too large, the time difference in sound wave propagation will cause a significant time delay in the sound signals received by the two microphone matrices. This delay will affect the accuracy of headphone audio processing, leading to sound distortion or incoherence. Furthermore, a larger distance will increase the phase difference between the two audio signals, affecting the sound synthesis effect. This is especially true in stereo and active noise cancellation applications, where phase cancellation may occur, reducing overall audio quality.
[0083] To address this, this application designs the second microphone matrix to be within a distance of 15mm to 40mm from the first microphone matrix. This helps the two microphone matrices better separate different sound sources, improving directional sound pickup, noise reduction performance, and speech clarity. Simultaneously, it avoids introducing significant time delays and phase differences due to excessive distance, ensuring that the sound signals received by the two microphone matrices are essentially synchronized in time. This reduces distortion caused by time delays and facilitates precise audio processing, ensuring accurate synthesis and processing of sound signals, providing higher quality audio output, and thus improving call quality and user experience.
[0084] In some embodiments, refer to Figure 2 As shown, the headphone body 1 is equipped with a control unit, which is electrically connected to the first microphone matrix and the second microphone matrix respectively.
[0085] Specifically, the control unit may include a circuit board 12 and a control chip 13 disposed on the circuit board 12, which is responsible for receiving and processing audio signals from the first microphone matrix and the second microphone matrix, and performing corresponding control and adjustment according to different usage scenarios (such as calls, active noise cancellation, hearing aids, etc.), and intelligently switching the working state of the first microphone matrix and the second microphone matrix to achieve the best audio effect.
[0086] Call mode and active noise cancellation mode: The control chip 13 can determine whether there is a windy environment based on the sound characteristics received by the microphone, or detect wind conditions through sensors such as wind speed and direction, and adjust the microphone's working status accordingly. For example, in windless conditions, both the first and second microphone matrices are activated simultaneously. The two microphone matrices work together to achieve a wider noise cancellation angle, cover more noise sources, and provide a more comprehensive noise cancellation experience. In headwind conditions, the first microphone matrix is turned off and the second microphone matrix is activated to reduce wind noise interference. In tailwind conditions, the first microphone matrix is activated and the second microphone matrix is turned off to reduce wind noise interference.
[0087] Auxiliary hearing mode: Control chip 13 can independently enable the second microphone matrix to avoid feedback problems caused by speaker sound being picked up and to improve gain settings.
[0088] Therefore, by setting a control unit inside the headset body 1, the embodiments of this application can realize the coordinated control and operation of the first microphone matrix and the second microphone matrix, which can not only significantly improve the call quality, but also enhance the overall performance of the headset in various application scenarios.
[0089] In some embodiments, refer to Figure 2 As shown, the control unit also includes a first control switch (not shown) and a second control switch (not shown) disposed on the earphone body 1 and / or ear hook 2, and the first control switch and the second control switch are electrically connected to the control chip 13.
[0090] Specifically, the first control switch can be located on the earphone body 1 or the ear hook 2, and is used to turn the auxiliary hearing function on or off. It is off by default, and the auxiliary hearing function is turned on when pressed. When the user needs enhanced hearing assistance, he / she can activate the auxiliary hearing mode by pressing the first control switch, which turns off the first microphone matrix and starts the second microphone matrix to provide high-gain sound pickup.
[0091] The second control switch can be located on the earphone body 1 or the ear hook 2, and is used to turn the active noise cancellation function on or off. It is off by default, and the active noise cancellation function is turned on when pressed. When the user wants to reduce ambient noise interference, they can activate the active noise cancellation mode by pressing the second control switch, and obtain wind information to intelligently switch the working state of the microphone according to the wind conditions to ensure the best noise cancellation effect.
[0092] Therefore, users can manually enable or disable the corresponding functions according to their actual needs. This design not only enhances the user's autonomy but also provides greater flexibility and a more personalized experience.
[0093] The control method for the headphones according to the above embodiments provided in this application will continue to be described below.
[0094] In some embodiments, refer to Figure 6 As shown, this application also provides a method for controlling headphones according to the above embodiments, including the following steps:
[0095] S601, Obtain control signals.
[0096] Control signals can indicate different functional requirements, such as hearing assistance, communication, and active noise cancellation.
[0097] S602. Determine that the control signal is an auxiliary hearing signal, turn off the first microphone matrix, and turn on the second microphone matrix.
[0098] When the control signal is an auxiliary hearing signal (such as when the user presses the first control switch), in auxiliary hearing mode, the first microphone matrix is located inside the earphone body 1, close to the speaker inside the earphone body 1, which is prone to echo and feedback problems. Therefore, turning off the first microphone matrix can avoid this interference. At the same time, the second microphone matrix is enabled, which is located on the ear hook 2, away from the speaker, and can provide a higher gain setting while reducing the risk of sound feedback, thereby providing a better assistive effect for hearing-impaired users.
[0099] S603. Determine that the control signal is a call signal and / or an active noise cancellation signal, and obtain the wind condition information of the location of the headphones.
[0100] If the control signal indicates call mode (e.g., call signal detected) and / or active noise cancellation mode (e.g., user presses second control switch), further assessment of current environmental conditions, especially wind information, is required. For example, wind information about the headset's location can be obtained through a built-in wind speed sensor or other environmental detection modules (e.g., accelerometer, gyroscope, etc.) to make appropriate adjustments.
[0101] S604. Control the operation of the first microphone matrix and the second microphone matrix based on the wind conditions where the headphones are located.
[0102] If a windless environment is detected, that is, if the wind condition information is determined to be windless, the first microphone matrix and the second microphone matrix can be activated simultaneously. Their collaborative work can achieve a wider noise reduction angle, cover more noise sources, and provide a more comprehensive noise reduction experience.
[0103] If a headwind environment is detected, i.e., the wind condition is determined to be headwind, the first microphone matrix is turned off (due to the obstruction of the auricle, the wind is more likely to blow towards the first microphone matrix on the earphone body 1, so the first microphone matrix on the earphone body 1 detects more noise), and the second microphone matrix is turned on to reduce wind noise interference and improve call quality.
[0104] If a tailwind is detected, indicating a tailwind condition, the first microphone matrix is activated while the second microphone matrix is deactivated. (When a user walks with the wind, the wind is more likely to blow onto the second microphone matrix on the ear hook 2 due to the obstruction of the ear, resulting in greater wind noise being detected by the second microphone matrix on the ear hook 2.) This is also to reduce the impact of wind noise and maintain high sound pickup quality.
[0105] Therefore, the headphone control method provided in this application embodiment can optimize the microphone's operating state according to the actual application environment to adapt to different usage scenarios, thereby effectively improving the user experience.
[0106] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
