Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a pair of headphones. Background Technology

[0002] Headphones, as personal audio devices, receive electrical signals from media players or receivers and convert these signals into audible sound waves using speakers placed close to the ears. Depending on the classification method, they can include on-ear headphones, over-ear headphones, wireless headphones, noise-canceling headphones, etc.

[0003] However, current headphone devices are mainly used for audio playback and reception, with relatively limited functionality, and cannot meet more usage needs. Summary of the Invention

[0004] This application provides a type of headphone to address the problem that current headphone devices have limited functionality and cannot meet a wide range of user needs.

[0005] To achieve the above objectives, the technical solution of this application is as follows:

[0006] This application provides an earphone, including: a sound-emitting part disposed on the front side of the ear, a main body disposed on the back side of the ear, and an ear hook part connecting the sound-emitting part and the main body;

[0007] The sound-emitting part includes: a first housing, and a speaker unit, a microphone unit, a camera device and a voice processing unit disposed in the inner cavity of the first housing. The first housing has a viewing hole, and the camera device is disposed at the viewing hole.

[0008] The camera device is configured to capture images of the area in front of a person's face when the headphones are being worn, and the voice processing unit is used to recognize and process the voice of the headphone wearer.

[0009] By incorporating a camera device, the earphones gain independent video recording capabilities, allowing the wearer to activate the camera as needed while wearing the headphones to capture images or video information. Furthermore, the inclusion of a voice processing unit enables the earphones to perform voice recognition and processing, enhancing their voice pickup capabilities. These features, combined with the earphones provided in this application, facilitate the fulfillment of more user needs, improve overall earphone performance, and enhance the user experience.

[0010] In one possible implementation, the viewing aperture is located on the side of the first housing facing in front of the ear.

[0011] In this way, the camera device can face directly into the wearer's field of vision, which helps to avoid the wearer's ears blocking the camera, reduce blind spots caused by the face, and maximize the shooting range of the camera device.

[0012] In one possible implementation, the inner cavity of the first housing includes a first chamber and a second chamber, wherein the camera device is located in the first chamber and the speaker unit is located in the second chamber, with the first chamber located in front of the second chamber along the sagittal axis of the human body.

[0013] This design effectively prevents the second chamber from obstructing the camera device, allowing the camera to be aimed at the wearer's line of sight and further enhancing the user experience.

[0014] In one possible implementation, the projection of the camera device onto the sagittal plane of the human body is located in front of the projection of the speaker unit onto the sagittal plane of the human body.

[0015] In this way, the user experience is optimized, ensuring that the camera device has a wider field of view and better captures images, while the speaker unit can provide clear sound output without affecting the camera device's recording function.

[0016] In one possible implementation, when worn, at least a portion of the first chamber is located in front of the tragus, and the second chamber is located in the concha.

[0017] This helps optimize the camera's field of view, ensuring that the camera can clearly capture the image in front of the wearer. In addition, it also ensures that the speaker unit is close to the wearer's ear canal, thereby providing a clearer, more immersive audio experience and improving sound quality.

[0018] In one possible implementation, the first housing includes an inner wall facing the face along the coronal axis of the human body, an outer wall facing away from the face, and a transition connecting wall surrounding the periphery of the inner wall and the outer wall, wherein the viewing aperture is located in the region of the transition connecting wall facing the front of the face.

[0019] In this way, the camera lens can be directly aimed at the wearer's front, including the wearer's gestures and the environment in front, ensuring the camera's field of view and image quality.

[0020] In one possible implementation, the transition connecting wall includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected in sequence, with the first sidewall and the third sidewall arranged opposite to each other, the second sidewall and the fourth sidewall arranged opposite to each other, and at least one of the first sidewall and the second sidewall facing forward of the face, and the viewing aperture is located in one of the first sidewall, the second sidewall, and the transition area between the first sidewall and the second sidewall.

[0021] In some wearing methods, the first sidewall is the portion of the transition connecting wall that directly faces the user's front. If the viewing aperture is located on the first sidewall, its placement ensures that the camera device can capture the user's field of vision. Similarly, in other wearing methods, the second sidewall is the portion of the transition connecting wall that directly faces the user's front. In still other wearing methods, the transition area between the first and second sidewalls is the portion of the support that faces the user's front.

[0022] In one possible implementation, the inner cavity of the first housing includes a first chamber and a second chamber, wherein the camera device is located in the first chamber and the speaker unit is located in the second chamber, along the coronal axis of the human body, with the first chamber located on the side of the second chamber away from the face.

[0023] This design helps avoid mutual interference between the camera device and the speaker unit. The first chamber is located on the side of the second chamber away from the face, allowing the camera device to face directly into the wearer's field of vision, avoiding the wearer's ears from blocking the camera device, reducing blind spots caused by the face, and maximizing the shooting range of the camera device.

[0024] In one possible implementation, the projection of the camera device onto the sagittal plane of the human body at least partially overlaps with the projection of the speaker unit onto the sagittal plane of the human body.

[0025] In this way, the camera device and the speaker unit are relatively close in the front-back direction of the human body, which optimizes the internal space of the headphones. In order to ensure the normal use of the camera device and the speaker unit, the camera device is located on the side away from the human face relative to the speaker unit, which maximizes the shooting range of the camera device.

[0026] In one possible implementation, when worn, the second chamber is located in the concha cavity, and at least a portion of the projection of the first chamber onto the sagittal plane of the human body is located in the concha cavity.

[0027] This design ensures that the speaker unit fits snugly against the wearer's ear canal, providing a clear and immersive audio experience. It also leverages the spatial advantages of the ear structure to enhance wearing comfort and stability. Furthermore, it guarantees sufficient space for the camera device to capture images.

[0028] In one possible implementation, the first housing includes an inner wall facing the face along the coronal axis of the human body and an outer wall facing away from the face. The outer wall includes an extensional region extending away from the face along the coronal axis of the human body. The viewing aperture and the camera device are both located in the extensional region.

[0029] In this way, the viewing aperture and camera device are positioned on the outer area, optimizing the overall appearance of the headphones and ensuring that the camera device can capture high-quality images or videos without being interfered with or restricted by improper positioning.

[0030] In one possible implementation, the extended region is arranged opposite to the concha cavity of the human body along the coronal axis of the human body.

[0031] By arranging the headphones relative to each other along the coronal axis of the human body, a more reasonable installation space is provided for the viewing aperture and camera device, further enhancing the practicality and functionality of the headphones.

[0032] In one possible implementation, the extended region extends beyond the auricle along the coronal axis of the human body.

[0033] This setup facilitates the installation of camera devices, allowing the cameras to face directly into the wearer's field of vision and capture images of the front area of ​​the face without obstruction, thus reducing blind spots caused by the face.

[0034] In one possible implementation, the extended region further extends downward along the vertical axis of the human body. The extended region includes a first end and a second end along the vertical axis of the human body. In the coronal axis direction of the human body, the distance between the second end and the face is greater than the distance between the first end and the face. The camera device and the field of view are both located at the second end.

[0035] Both the camera and the viewing aperture are located at the second end. This allows the camera to capture a wider field of view, enhancing the interactive experience of the headphones.

[0036] In one possible implementation, the extended region is connected to the portion of the first housing other than the extended region by a circular arc transition.

[0037] The rounded transition enhances the aesthetics of the headphones and ensures comfort for the wearer's hand or face when in contact with the headphones in different usage scenarios.

[0038] In one possible implementation, the first housing includes an inner wall facing the face along the coronal axis of the human body, the inner wall including a first region that, in the wearing state, is in direct contact with the preauricular region; the voice processing unit is located inside the first housing opposite to the first region.

[0039] In this way, the first area can directly contact the wearer's ear area when the earphone is worn, ensuring the stability of the earphone during wear. A voice processing unit is located inside the first shell. This optimizes the use of internal space and allows the voice processing unit to more accurately capture the wearer's voice signals, thereby improving the clarity and accuracy of voice interaction.

[0040] In one possible implementation, when worn, the first region is located in the preauricular region above the tragus.

[0041] This design conforms to ergonomic principles while ensuring both wearing comfort and stability. Furthermore, it effectively reduces direct pressure on sensitive areas of the wearer's face and ensures a close fit between the headphones and the ear's contours during wear, preventing discomfort caused by movement or displacement.

[0042] In one possible implementation, the voice processing unit is configured to acquire the vocal state of the headphone wearer by detecting vibrations in the human head.

[0043] By setting up a voice processing unit, the headset can provide real-time feedback on the wearer's pronunciation and effectively distinguish between background noise and valid speech, thereby improving the accuracy and clarity of speech recognition.

[0044] In one possible implementation, the inner wall of the first housing is provided with a clearance portion adapted to the concha cavity, and the clearance portion is located in the area between the camera device and the speaker unit along the sagittal axis of the human body.

[0045] In this way, the recessed part can fit into the concha cavity, providing a support point for the earphone. The concave design also reduces the pressure of the earphone on the concha cavity, improving wearing comfort.

[0046] In one possible implementation, the first housing is provided with a first sound pickup hole and a second sound pickup hole. The first sound pickup hole is located on the inner side wall of the first housing and is positioned facing the front of the face. The second sound pickup hole is located on the outer side wall of the first housing.

[0047] By using the first and second microphone holes together, the headphones can achieve omnidirectional and high-precision sound acquisition, bringing the wearer a more natural and smooth voice interaction experience.

[0048] In one possible implementation, the sound-generating part further includes a motherboard and an image processor, along the coronal axis of the human body, with the image processor located on the side of the motherboard facing the human body.

[0049] The motherboard processes various signals and data to ensure the stable operation of the entire system. The image processor processes image information; this configuration also facilitates collaboration between the image processor and the camera device, jointly providing users with a richer and more intuitive information interaction experience.

[0050] In one possible implementation, it further includes: a communication module located within the first housing, the communication module being electrically connected to the camera device and transmitting images captured by the camera device to an external device.

[0051] The communication module enables the headset to transmit data directly with external devices without relying on smartphones or other devices as intermediaries, thus improving the efficiency and stability of data transmission.

[0052] The headphones provided in this application include a sound-generating part, a main body, and an ear hook. The main body houses a battery to power the sound-generating part. The ear hook connects the sound-generating part and the main body, facilitating a secure fit for the wearer. The sound-generating part includes a first housing and a speaker unit, a microphone unit, a camera device, and a voice processing unit disposed within the cavity of the first housing. The camera device enables the headphones to have independent video recording capabilities, allowing the wearer to activate the camera device as needed while wearing the headphones to obtain image or video information. The voice processing unit enables the headphones to perform voice recognition and processing, improving their voice pickup capabilities. With this configuration, the headphones provided in this application can meet more of the wearer's usage needs, enhancing the overall performance and user experience of the headphones.

[0076] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0077] Headphones are devices that convert electrical signals into sound, typically used for personal audio listening. Specifically, they receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Examples of headphone types include in-ear headphones, semi-in-ear headphones, over-ear headphones, ear-hook headphones, bone conduction headphones, wired headphones, wireless headphones, and noise-canceling headphones. Current headphone devices are primarily used for audio playback and reception, with relatively limited functionality and unable to meet a wider range of usage needs.

[0078] In view of this, this application provides an earphone, which includes a sound-emitting part, a main body, and an ear hook. The main body houses a battery to power the sound-emitting part. The ear hook connects the sound-emitting part and the main body, facilitating a secure fit for the wearer. The sound-emitting part includes a first housing and a speaker unit, a microphone unit, a camera device, and a voice processing unit disposed within the cavity of the first housing. The camera device enables the earphone to have independent video recording capabilities, allowing the wearer to activate the camera device as needed while wearing the earphone to obtain image or video information. The voice processing unit enables the earphone to perform voice recognition and processing, improving its voice pickup capabilities. With this configuration, the earphone provided by this application can meet more of the wearer's usage needs, improving the overall performance and user experience of the earphone.

[0079] The following is in conjunction with the appendix Figures 1-12 This application will be described in detail with reference to specific embodiments.

[0080] The headphones in this application embodiment can be in-ear headphones, semi-in-ear headphones, bone conduction headphones, wireless headphones, etc. The following description uses wireless headphones as an example to elaborate on the embodiments of this application.

[0081] Combination Figures 1-4 as well as Figure 7 and Figure 8 The headphones according to this application embodiment may include a sound-emitting part 10 disposed on the front side of the ear, a main body part 20 disposed on the back side of the ear, and an ear hook part 30 connecting the sound-emitting part 10 and the main body part 20. The reasonable arrangement of the sound-emitting part 10, the main body part 20 and the ear hook part 30 helps to ensure the stability and comfort of the headphones when worn, as well as to ensure the balance of the center of gravity of the headphones on the front and back sides of the ear.

[0082] Among them, combined Figures 2-3 as well as Figure 9 The sound-emitting part 10 may include a first housing 100, and a speaker unit 200, a microphone unit 300, a camera device 400, and a voice processing unit 500 disposed within the cavity of the first housing 100. The main body 20 may be used to house a battery 800, which is used to power the various functional components of the sound-emitting part 10.

[0083] The speaker unit 200 is disposed in the cavity of the first housing 100 to provide high-quality audio output, ensuring that the wearer can obtain a clear and full listening experience when listening to music, making calls or other audio content.

[0084] In addition, the speaker unit 10 integrates a microphone unit 300, which can accurately capture the wearer's voice commands or call sounds, providing a foundation for voice interaction.

[0085] Furthermore, to facilitate the installation of the camera device 400, a viewing aperture 110 is provided on the first housing 100. The viewing aperture 110 can be circular, square, elliptical, or any other arbitrary shape; this embodiment does not impose any limitations on this. The camera device 400 is located at the viewing aperture 110 and is configured to capture images of the area in front of the face when the headphones are worn. This configuration allows the headphones to directly capture the area in front of the wearer's face through the viewing aperture 110 when worn, obtaining image or video information in the wearer's line of sight. For example, in conjunction with... Figure 1 and Figure 2 The camera device 400 has a wider field of vision than the human body, which helps to ensure the comprehensiveness of information capture.

[0086] Furthermore, combining Figure 4 and Figure 9 The inner cavity of the first housing 100 may also house a voice processing unit (VPU). The voice processing unit 500 can recognize and process the vibrations generated when the earphone wearer speaks, that is, it captures voice signals through bone conduction. Compared to traditional air conduction microphones, this method can more effectively isolate environmental noise and improve the clarity and purity of the voice. For example, while wearing the earphone, the wearer can issue a command to activate the camera as needed. After acquiring the voice signal, the voice processing unit 500 recognizes and processes it, thereby activating the camera device 400. Of course, the function of the voice processing unit 500 is only provided as an example, and this embodiment does not limit its functionality.

[0087] By incorporating a camera device 400, the headphones possess an independent camera function, allowing the wearer to activate the camera device 400 as needed while wearing the headphones to obtain image or video information. The inclusion of a voice processing unit 500 enables the headphones to perform voice recognition and processing, improving their voice pickup capabilities. Compared to headphones in related technologies that primarily function as audio playback and reception devices, this design allows for greater fulfillment of the wearer's needs, enhancing overall headphone performance and improving the user experience.

[0088] Furthermore, compared to traditional smart glasses and smartwatches, the earphone design in this embodiment places the sound-emitting part 10 in front of the ear and the main body 20 behind the ear, connected by the ear hook 30. This helps to form a stable wearing structure, does not put pressure on the bridge of the nose, and does not affect the use of the camera due to wrist movement, thus improving wearing comfort and convenience.

[0089] For example, the headphones in this application embodiment can be used in scenarios such as daily office work, remote meetings, online education, and outdoor hiking. For instance, in remote meetings, the headphones can capture the wearer's voice and gesture information to provide accurate command input for AI; in online education, the headphones can record students' learning status and progress online to improve personalized education; and in outdoor hiking, the headphones can capture environmental or weather information in real time to ensure the wearer's safety and information storage in the wild.

[0090] Optionally, the camera device 400 in the earphone of this embodiment can also be equipped with privacy protection to control the camera's on and off time, as well as limit the range and objects of data transmission, to ensure the wearer's privacy and security.

[0091] In this embodiment, the viewing aperture 110 is located on the side of the first housing 100 facing the front of the ear.

[0092] Understandably, placing the viewing aperture 110 in front of the ear ensures that when the wearer wears headphones, the camera device 400 can directly face the wearer's frontal field of vision, thereby capturing images of the front area of ​​the face without obstruction. This avoids the wearer's ears blocking the camera, reduces blind spots caused by the face, maximizes the shooting range of the camera device 400, and allows the wearer to obtain clear and natural images.

[0093] Combination Figures 10-12The wearing of the left and right earphones ensures that a camera device 400 is installed at each of the wearer's left and right ears. For example, the normal field of vision of the human eye is the first field of vision 410, and the field of vision of the camera device 400 is the second field of vision 420. When the earphones are worn, the second field of vision 420 can cover the first field of vision 410. For example, the camera device 400 can be set to a wide-angle lens or an adjustable angle configuration to ensure that if the earphones are tilted during the wearing process, the second field of vision 420 of the camera device 400 can still cover the first field of vision 410 of the human eye.

[0094] In addition, this layout helps to avoid direct contact between the viewing hole 110 and the wearer's ear or other parts of the face, reducing discomfort during wear.

[0095] In the embodiments of this application, reference is made to Figure 4 The inner cavity of the first housing 100 includes a first chamber 120 and a second chamber 130, wherein the camera device 400 is located in the first chamber 120 and the speaker unit 200 is located in the second chamber 130. Along the sagittal axis of the human body (i.e., the front-back direction of the human body), the first chamber 120 is located in front of the second chamber 130.

[0096] In practice, the camera device 400 is positioned within the first chamber 120. This arrangement helps ensure the camera device 400 remains stable within the first chamber 120 and also ensures that the camera device 400 can flexibly capture images in front of the wearer. The position of the first chamber 120 takes ergonomic principles into account, allowing the camera device 400 to be aligned with the wearer's line of sight, thus improving the user experience.

[0097] For example, the speaker unit 200 is located within the second chamber 130, which helps reduce mutual interference between the speaker unit 200 and the camera device 400. Along the sagittal axis of the human body, the first chamber 120 is located in front of the second chamber 130, which conforms to the natural posture of the wearer and can avoid the second chamber 130 from obstructing the camera device 400.

[0098] In this embodiment, the projection of the camera device 400 onto the sagittal plane of the human body is located in front of the projection of the speaker unit 200 onto the sagittal plane of the human body.

[0099] In this configuration, when the human sagittal plane is used as a reference plane, the projection position of the camera device 400 is at a point on the human sagittal plane, and this point is located in front of the speaker unit 200 at the same projection point on the human sagittal plane. This setting optimizes the user experience and expands the field of view of the camera device 400, reducing blind spots for better image capture. Meanwhile, the speaker unit 200 can provide clear sound output without affecting the camera function.

[0100] In this embodiment of the application, when worn, at least a portion of the first chamber 120 is located in front of the tragus, and the second chamber 130 is located in the concha cavity.

[0101] When worn, at least a portion of the first chamber 120 is located in front of the wearer's tragus. This configuration optimizes the viewing angle of the camera device 400, ensuring that the camera device 400 can clearly capture the image in front of the wearer, while also taking into account wearing comfort and stability.

[0102] Furthermore, the second chamber 130 is located within the concave cavity, a recessed area. This arrangement utilizes the spatial advantages of the ear structure, ensuring that the speaker unit 200 can be positioned close to the wearer's ear canal, thereby providing a clearer and more immersive audio experience. In addition, the enclosed nature of the concave cavity helps reduce interference from external noise, enhancing sound quality.

[0103] In the embodiments of this application, reference is made to Figure 2 The first housing 100 includes an inner wall 140 facing the face along the coronal axis of the human body (i.e., the left-right direction of the human body), an outer wall 150 facing away from the face, and a transition connecting wall 160 surrounding the periphery of the inner wall 140 and the outer wall 150. The viewing aperture 110 is located in the area of ​​the transition connecting wall 160 facing the front of the face.

[0104] With this setup, the camera lens of the camera device 400 can be directly aimed at the wearer's front, including the wearer's gestures and the environment in front, ensuring the camera range and image quality of the camera device 400, and also making the headphones look simple and beautiful overall.

[0105] It should be noted that the inner wall 140 faces the face, and its design takes into account the fit with the ear and surrounding tissues to ensure comfort and stability. The inner wall 140 can adopt an ergonomic curved design to reduce pressure on the skin.

[0106] In the embodiments of this application, reference is made to Figure 1 The transition connecting wall 160 includes a first sidewall 161, a second sidewall 162, a third sidewall 163, and a fourth sidewall 164 connected in sequence. The first sidewall 161 and the third sidewall 163 are arranged opposite to each other, and the second sidewall 162 and the fourth sidewall 164 are arranged opposite to each other. At least one of the first sidewall 161 and the second sidewall 162 faces the front of the face. The viewing hole 110 is provided in one of the transition areas of the first sidewall 161, the second sidewall 162, and the first sidewall 161 and the second sidewall 162.

[0107] As can be seen, the viewing aperture 110 can be located on the first sidewall 161, the second sidewall 162, or the transition area between the first sidewall 161 and the second sidewall 162. In some wearing methods, the first sidewall 161 is the portion of the transition connecting wall 160 that directly faces the wearer's front. If the viewing aperture 110 is located on the first sidewall 161, its placement ensures that the camera device 400 can capture the field of view in front of the wearer. Similarly, in other wearing methods, the second sidewall 162 is the portion of the transition connecting wall 160 that directly faces the wearer's front. In still other wearing methods, the transition area between the first sidewall 161 and the second sidewall 162 is the portion of the bracket facing the wearer's front. This arrangement minimizes the blind spot of the camera device 400, allowing it to better acquire image information in front of the wearer.

[0108] In addition to being directly in front of the wearer, the optical axis can also be set off from the wearer's front within an appropriate range. For example, this range can be -10° to 10°. This range helps to capture specific angles, especially when it is necessary to capture environmental information or to take slightly downward or upward shots. The wearer can adjust the wearing method according to actual needs, and there are no restrictions here.

[0109] In the embodiments of this application, reference is made to Figure 4 The inner cavity of the first housing 100 includes a first chamber 120 and a second chamber 130, wherein the camera device 400 is located in the first chamber 120 and the speaker unit 200 is located in the second chamber 130. Along the coronal axis of the human body (i.e., the left-right direction of the human body), the first chamber 120 is located on the side of the second chamber 130 away from the human face.

[0110] In practice, the camera device 400 is housed within the first chamber 120, ensuring that the camera device 400 does not interfere with the operation of other components and can capture images stably and efficiently. The first chamber 120 provides space for the camera device 400, protecting it from external interference and damage.

[0111] For example, the speaker unit 200 is disposed within the second chamber 130, and the speaker unit 200 is positioned closer to the wearer's ear canal to ensure clear transmission and high-quality playback of audio signals. The second chamber 130 balances sound propagation characteristics with wearing comfort.

[0112] In terms of layout, along the coronal axis of the human body, the first chamber 120 is located on the side of the second chamber 130 furthest from the face. This arrangement helps reduce mutual interference between the camera device 400 and the speaker unit 200, ensuring that each function is fully utilized. Furthermore, the placement of the first chamber 120 on the side of the second chamber 130 furthest from the face allows the camera device 400 to directly face the wearer's forward field of vision, capturing images of the front area of ​​the face without obstruction. This avoids the wearer's ears obstructing the camera device 400, reduces blind spots caused by the face, and maximizes the shooting range of the camera device 400.

[0113] In this embodiment, the projection of the camera device 400 onto the sagittal plane of the human body at least partially overlaps with the projection of the speaker unit 200 onto the sagittal plane of the human body.

[0114] With this setup, the camera device 400 and the speaker unit 200 are relatively close to each other in the front-back direction of the human body. In order to ensure the normal use of the camera device 400 and the speaker unit 200, the camera device 400 is located on the side away from the human face relative to the speaker unit 200. This setup helps to optimize the internal space of the headphones and ensures that the shooting range of the camera device 400 is maximized.

[0115] In this embodiment of the application, when worn, the second chamber 130 is located in the concha cavity, and at least a portion of the projection of the first chamber 120 onto the sagittal plane of the human body is located in the concha cavity.

[0116] Specifically, the second chamber 130 is located within the wearer's concha. As a recessed area of ​​the ear, the concha provides a placement position for the speaker unit 200, thereby ensuring that the speaker unit 200 can fit closely to the wearer's ear canal to provide a clear and immersive audio experience. It also takes advantage of the spatial structure of the ear to improve wearing comfort and stability.

[0117] Furthermore, when the earphone is worn, at least a portion of the first chamber 120 is located within the projection area of ​​the concha cavity when projected with the sagittal plane of the human body as the reference plane. This ensures that the camera device 400 has sufficient space for image capture while also maintaining overall harmony and aesthetics during wear. The internal space of the earphone is optimized, and the shooting range of the camera device 400 is maximized.

[0118] In the embodiments of this application, combined with Figure 7 and Figure 8 The first housing 100 includes an inner wall 140 facing the face along the coronal axis of the human body and an outer wall 150 facing away from the face. The outer wall 150 includes an extension region 151 extending away from the face along the coronal axis of the human body (i.e., the left-right direction of the human body). The viewing aperture 110 and the camera device 400 are both located in the extension region 151.

[0119] In practice, the inner wall 140 is arranged along the coronal axis of the human body towards the face, ensuring a comfortable fit and appropriate distance between the device and the wearer's face.

[0120] The outer wall 150 features an extension region 151 that extends along the coronal axis of the human body, away from the face. The viewing aperture 110 and camera device 400 are positioned on the extension region 151, optimizing the overall appearance of the headphones and ensuring that the camera device 400 can capture high-quality images or videos without interference or limitation due to improper positioning. This design enhances both wearer comfort and multi-functionality.

[0121] In this embodiment of the application, the extended region 151 is arranged opposite to the concha cavity of the human body along the coronal axis of the human body.

[0122] It should be noted that by aligning the outer region 151 with the coronal axis of the human body, the outer region 151 avoids the main structures of the ear, reducing pressure on the wearer's ear and thus improving the overall wearing experience. Furthermore, this arrangement provides more reasonable installation space for the viewing aperture 110 and the camera device 400, further enhancing the practicality and functionality of the headphones.

[0123] In this embodiment of the application, when worn, the extended region 151 extends beyond the auricle along the coronal axis of the human body.

[0124] Specifically, the outer extension region 151 extends beyond the boundary of the auricle along the direction of the human coronal axis. This arrangement facilitates the installation of the camera device 400, allowing the camera device 400 to directly face the wearer's forward field of vision, capture images of the front area of ​​the face without obstruction, reduce blind spots caused by the face, and maximize the shooting range of the camera device 400.

[0125] In the embodiments of this application, reference is made to Figure 7 The extended region 151 also extends downward along the vertical axis of the human body. The extended region 151 includes a first end 1511 and a second end 1512 along the vertical axis of the human body. In the coronal axis direction of the human body, the distance between the second end 1512 and the face is greater than the distance between the first end 1511 and the face. The camera device 400 and the field of view 110 are both located at the second end 1512.

[0126] In this design, the first end 1511, serving as the upper part of the extension region 151, maintains a relatively close distance to the face. The second end 1512, serving as the extended end of the extension region 151, significantly increases the distance to the face along the coronal axis of the human body. Both the camera device 400 and the viewing aperture 110 are located at the second end 1512. This allows the camera device 400 to capture a wider field of view, which is beneficial for improving the interactive experience of the headphones.

[0127] In this embodiment, the extension region 151 is connected to the portion of the first housing 100 other than the extension region 151 by a circular arc transition.

[0128] Using rounded transitions enhances the aesthetics of the headphones and also improves the user experience from a functional perspective. This ensures comfort for the wearer's hand or face when in contact with the headphones in different usage scenarios, avoiding discomfort that might be caused by sharp edges.

[0129] In the embodiments of this application, reference is made to Figure 3 and Figure 4 as well as Figure 9 The first housing 100 includes an inner wall 140 facing the face along the coronal axis of the human body. The inner wall 140 includes a first region. In the wearing state, the first region is in direct contact with the preauricular region. The voice processing unit 500 is located inside the first housing 100 and is positioned opposite to the first region.

[0130] In practice, a first area is provided on the inner wall 140, which can directly contact the wearer's ear area when the headphones are worn. This design ensures the stability of the headphones during wear and also helps to reduce pressure on other areas of the face, thus improving the wearer's experience.

[0131] Furthermore, a voice processing unit 500 is disposed inside the first housing 100 at a position opposite to the first region. This arrangement optimizes the utilization of the internal space of the earphone and enables the voice processing unit 500 to more accurately capture the sound signals emitted by the wearer, thereby improving the clarity and accuracy of voice interaction. Thus, the earphones provided in this embodiment offer a convenient wearing experience and also achieve efficient voice interaction functionality.

[0132] In this embodiment of the application, when worn, the first region is located in the area in front of the ear above the tragus.

[0133] When the headphones are securely worn in the wearer's ear, the first area on the inner wall 140 is located in the area in front of the ear above the tragus. This design conforms to ergonomic principles and takes into account both wearing comfort and stability. In addition, it can effectively reduce direct pressure on the wearer's sensitive facial areas and ensure that the headphones fit the ear contour closely during wearing, preventing discomfort caused by shaking or displacement.

[0134] In this embodiment, the voice processing unit 500 is configured to obtain the vocal state of the headphone wearer by detecting vibrations of the human head.

[0135] In practical implementation, since the area above the tragus in front of the ear is the area of ​​skull vibration during human speech, the voice processing unit 500, located in the first area, can capture and process the subtle vibrations in the head caused by the earphone wearer's speech movements during voice communication. This process provides real-time feedback on the earphone wearer's speech status and effectively distinguishes between background noise and valid speech, thereby improving the accuracy and clarity of speech recognition.

[0136] In the embodiments of this application, reference is made to Figure 3 and Figure 8 The inner wall 140 of the first housing 100 is provided with a clearance portion 170 adapted to the concha cavity. Along the sagittal axis of the human body, the clearance portion 170 is located in the area between the camera device 400 and the speaker unit 200.

[0137] It should be noted that the concha is a component of the outer ear, located in the lower front of the auricle. It is a relatively concave area. The recessed portion 170 is concave in shape, so that it can fit into the concha and provide a support point for the headphones. The concave design also reduces the pressure of the headphones on the concha and improves wearing comfort. In addition, the recessed portion 170 is located in the area between the camera device 400 and the speaker unit 200. This arrangement ensures that the headphones fit snugly in the lower front of the concha when worn, ensuring the stability of the device and ensuring that the sound is accurately transmitted into the wearer's ear canal. Furthermore, it reduces interference from external noise and improves the sound quality of the headphones.

[0138] In the embodiments of this application, combined with Figure 3 and Figure 7 The first housing 100 is provided with a first sound pickup hole 180 and a second sound pickup hole 190. The first sound pickup hole 180 is located on the inner side wall 140 of the first housing 100 and is positioned facing the front of the face. The second sound pickup hole 190 is located on the outer side wall 150 of the first housing 100.

[0139] Understandably, the first housing 100 is equipped with dual microphone holes to optimize sound collection. Specifically, the first microphone hole 180 is located on the inner sidewall of the first housing 100 and faces the front of the face. This arrangement ensures that the first microphone hole 180 is close to the wearer's mouth area, effectively capturing the wearer's voice, reducing ambient noise interference, and improving the clarity and accuracy of voice recording.

[0140] The first pickup hole 180 can be set to two, which can improve the voice capture effect. Of course, this embodiment does not limit it.

[0141] Furthermore, the second pickup hole 190 is located on the outer wall 150 of the first housing 100. The second pickup hole 190 further widens the sound collection range and can capture sound information from different directions. Through the combined use of the first pickup hole 180 and the second pickup hole 190, the headphones in this embodiment can achieve omnidirectional and high-precision sound acquisition, bringing the wearer a more natural and smooth voice interaction experience.

[0142] In the embodiments of this application, reference is made to Figure 5 and Figure 9 The sound-emitting part 10 also includes a motherboard 600 and an image processor 700, with the image processor 700 located on the side of the motherboard 600 facing the human body along the coronal axis.

[0143] The motherboard 600 is used to process various signals and data, and is responsible for coordinating the work between various components to ensure the stable operation of the entire system.

[0144] Furthermore, the image processor 700 is positioned along the coronal axis of the human body (i.e., the left-right direction of the human body), and is located on the side of the motherboard 600 facing the human body. The image processor 700 is used to process image information. This configuration also facilitates the collaborative work between the image processor 700 and the camera device 400, jointly providing users with a richer and more intuitive information interaction experience.

[0145] In this embodiment of the application, the earphone may further include: a communication module (not shown in the figure), the communication module is located inside the first housing 100, the communication module is electrically connected to the camera device 400, and wirelessly transmits the images captured by the camera device 400 to an external device. For example, the communication module may include at least one of a Bluetooth module, a WIFI module, and a mobile cellular network communication module.

[0146] It should be noted that the camera device 400 is electrically connected to the communication module. The camera device 400 is configured to capture images of the area in front of the face when the headphones are worn, and send the images or videos captured by the camera device 400 to external devices, such as mobile phones or tablets, through the communication module. In this way, the communication module enables the headphones to directly transmit data with external devices to meet the user's needs and improve the user experience.
