[0061] The specific embodiments of the present application have been shown in the above-mentioned drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the concept of the present application in any way, but to illustrate the concept of the present application for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0062] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0063] An earphone is a device for converting electrical signals into sound, which is usually used for personal audio listening. Specifically, it converts electrical signals from a media player or a receiver into audible sound waves through a loudspeaker close to the ear. Exemplarily, earphones are classified into in-ear earphones, semi-in-ear earphones, head-mounted earphones, hanging earphones, bone conduction earphones, wired earphones, wireless earphones, noise reduction earphones, etc. The current earphone devices are mainly used for audio playing and receiving, and have a single function, which cannot meet more use requirements.

[0064] Therefore, the earphone provided by the application can realize more use requirements of the wearer, and improves the overall performance and user experience of the earphone.

[0065] The application will be described in detail below with reference to the specific embodiments of Figs. 1-16.

[0066] Firstly, referring to Figs. 1-12, the earphone of the embodiment of the application can be an in-ear earphone, a semi-in-ear earphone, a bone conduction earphone, a wireless earphone, etc. The embodiment of the application will be described below taking the wireless earphone as an example.

[0067] In combination with Figs. 1-4 and Figs. 7 and 8, the earphone of the embodiment of the application can include a sound production part 10 arranged on the front side of the ear, a main body part 20 arranged on the back side of the ear, and an ear hook part 30 connecting the sound production part 10 and the main body part 20. Through the reasonable arrangement of the sound production part 10, the main body part 20 and the ear hook part 30, the stability and comfort of the earphone when worn can be ensured, and the balance of the center of gravity of the earphone on the front side of the ear and the back side of the ear can be ensured.

[0068] In combination with Figs. 2-3 and Fig. 9, the sound production part 10 can include a first shell 100, and a loudspeaker unit 200, a microphone unit 300, a camera 400 and a voice processing unit 500 arranged in the inner cavity of the first shell 100. The main body part 20 can be used to arrange a power supply device 800, which can be a battery, for supplying power to each functional component of the sound production part 10.

[0069] The loudspeaker unit 200 is arranged in the inner cavity of the first shell 100, for providing high-quality audio output, so that the wearer can obtain a clear and full auditory experience when listening to music, talking or other audio content.

[0070] In addition, the sound production part 10 integrates the microphone unit 300, which can accurately capture the voice instructions or talking sounds of the wearer, and provides a basis for voice interaction.

[0071] Further, in order to realize the installation of the camera 400, the first shell 100 is provided with a field of view hole 110, which can be circular, square, oval or any other shape, and the present embodiment does not make any limitation in this regard. The camera 400 is arranged at the field of view hole 110, and the camera 400 is configured to be able to take pictures of the area in front of the face when the earphone is in the wearing state. In this way, the earphone can directly capture the area in front of the face of the wearer through the field of view hole 110 when it is worn, and obtain image or video information in the line of sight direction of the wearer. For example, in combination with FIGS. 1 and 2, the camera 400 has a wider field of view than the human body, which is conducive to ensuring the comprehensiveness of information capture.

[0072] Further, in combination with FIGS. 4 and 9, the inner cavity of the first shell 100 can also be provided with a voice processing unit 500 (VPU), which can identify and process the vibration generated when the wearer of the earphone speaks, that is, capture the voice signal through bone conduction. Compared with the traditional air conduction microphone, it can more effectively isolate environmental noise and improve the clarity and purity of the voice. For example, the wearer can issue an instruction to enable the camera in the wearing state as needed, and the voice processing unit 500 identifies and processes the voice signal after obtaining it, and then starts the camera 400. Of course, the function of the voice processing unit 500 is only exemplarily given, and the present embodiment does not make any limitation in this regard.

[0073] By providing the camera 400, the earphone has an independent camera function, so that the wearer can wake up the camera 400 to obtain image or video information as needed in the wearing state. By providing the voice processing unit 500, the earphone has voice recognition and processing functions, which improves the voice pickup capability of the earphone. In this way, compared with the earphone in the related art which is mainly used for audio playing and receiving and has a relatively single function, the earphone provided by the present application helps to realize more use requirements of the wearer and improves the overall performance of the earphone and the user experience.

[0074] In addition, compared with the traditional smart glasses and smart watches, the earphone design in the present embodiment places the sound generating part 10 on the front side of the ear, the main part 20 on the rear side of the ear, and connects them through the ear hanging part 30, which helps to form a stable wearing structure, does not bring pressure to the nose bridge, and does not affect the use of the camera due to wrist shaking, thereby improving the wearing comfort and convenience.

[0075] Exemplarily, the earphone of the embodiment of the present application can be used in daily office, remote conference, online education, field hiking and the like. For example, in the remote conference, the earphone can capture the sound and gesture information of the wearer to provide accurate instruction input for the AI; in the online education, the earphone can record the learning state and progress of the student online to perfect the personalized education; in the field hiking, the earphone can capture the environmental or weather information in real time to realize the field safety and information reserve of the wearer.

[0076] Optionally, the camera 400 in the earphone of the embodiment can also be provided with privacy protection to control the opening and closing time of the camera, and limit the range and object of data transmission, so as to ensure the privacy safety of the wearer.

[0077] In the embodiment of the present application, the view hole 110 is located on the side of the first shell 100 facing the front of the ear.

[0078] It can be understood that placing the view hole 110 in front of the ear ensures that when the wearer wears the earphone, the camera 400 can directly face the front view of the wearer, so as to capture the image of the front side of the face without obstruction, avoid the obstruction of the ear of the wearer to the camera, reduce the visual blind area caused by the face, ensure the maximization of the shooting range of the camera 400, and make the wearer obtain clear and natural picture effect.

[0079] In combination with FIGS. 10-12, the wearing of the left and right earphones can ensure that the left and right ears of the wearer are respectively provided with the camera 400. Exemplarily, the normal view of the human eye is the first view 410, and the view of the camera 400 is the second view 420. When the earphone is worn, the second view 420 can cover the first view 410. Exemplarily, the camera 400 can be provided as a wide-angle lens or an adjustable angle configuration to ensure that if the earphone is tilted during wearing, the second view 420 of the camera 400 can still cover the first view 410 of the human eye.

[0080] In addition, such layout also helps to avoid direct contact between the view hole 110 and the ear or other parts of the face of the wearer, and reduce the discomfort during wearing.

[0081] In the embodiment of the present application, referring to FIG. 4, the inner cavity of the first shell 100 includes a first chamber 120 and a second chamber 130, wherein the camera 400 is located in the first chamber 120, and the speaker unit 200 is located in the second chamber 130. Along the sagittal axis direction of the human body (i.e. the front and back direction of the human body), the first chamber 120 is located on the front side of the second chamber 130.

[0082] In a specific implementation, the camera 400 is arranged in the first chamber 120, which helps to ensure that the camera 400 is stable in the first chamber 120, and in addition, ensures that the camera 400 can capture images in front of the wearer flexibly. The position of the first chamber 120 takes into account the ergonomic principle, so that the camera 400 can be aligned with the line of sight of the wearer, improving the user experience.

[0083] For example, the speaker unit 200 is located in the second chamber 130, which helps to reduce the mutual interference between the speaker unit 200 and the camera 400. Along the sagittal axis of the human body, the first chamber 120 is arranged at the front side of the second chamber 130, so as to conform to the natural state of the wearer when wearing, and to avoid the second chamber 130 from blocking the camera 400.

[0084] In the embodiment of the present application, the projection of the camera 400 on the sagittal plane of the human body is located in front of the projection of the speaker unit 200 on the sagittal plane of the human body.

[0085] When the sagittal plane of the human body is taken as the reference plane, the projection position of the camera 400 on the sagittal plane of the human body is a certain point, and this point is located in front of the projection point of the speaker unit 200 on the same sagittal plane of the human body. In this way, the user experience of the wearer is optimized, and the shooting field of view of the camera 400 can be enlarged, the blind area can be reduced, and the picture can be captured better, while the speaker unit 200 can provide clear sound output without affecting the camera function.

[0086] In the embodiment of the present application, in the wearing state, at least part of the first chamber 120 is located in front of the tragus, and the second chamber 130 is located in the concha.

[0087] In the wearing state, at least part of the first chamber 120 is located in front of the tragus of the wearer. In this way, the viewing angle of the camera 400 is optimized, and it is ensured that the camera 400 can clearly capture images in front of the wearer, and in addition, the comfort and stability of wearing are also taken into account.

[0088] Further, the second chamber 130 is arranged in the concave area of the concha. In this way, the spatial advantage of the ear structure is utilized, and it is ensured that the speaker unit 200 can be close to the ear canal of the wearer, thereby providing a clearer and more immersive audio experience. In addition, the wrapping property of the concha helps to reduce the interference of external noise and improve the sound quality effect.

[0089] In the embodiment of the present application, referring to FIG. 2, the first shell 100 includes an inner side wall 140 facing the human face along the human coronal axis direction (i.e., the left-right direction of the human body), an outer side wall 150 facing away from the human face, and a transition connecting wall 160 surrounding the periphery between the inner side wall 140 and the outer side wall 150, and the field-of-view hole 110 is arranged at the area of the transition connecting wall 160 facing the front of the human face.

[0090] In this way, the lens of the camera 400 can be directly aimed at the front of the wearer, including the hand gestures of the wearer and the environment in front, ensuring the camera range and image quality of the camera 400, and also making the earphone as a whole simple and beautiful.

[0091] It should be noted that the inner side wall 140 is the side facing the human face, and the inner side wall 140 is arranged considering the fit with the ear and the surrounding tissue to ensure the comfort and stability of wearing. The inner side wall 140 can adopt a curve design conforming to ergonomics to reduce the feeling of oppression on the skin.

[0092] In the embodiment of the present application, referring to FIG. 1, the transition connecting wall 160 includes a first side wall 161, a second side wall 162, a third side wall 163, and a fourth side wall 164 connected in sequence, the first side wall 161 and the third side wall 163 are oppositely arranged, the second side wall 162 and the fourth side wall 164 are oppositely arranged, and at least one of the first side wall 161 and the second side wall 162 faces the front of the human face, and the field-of-view hole 110 is arranged on one of the first side wall 161, the second side wall 162, and the transition zone of the first side wall 161 and the second side wall 162.

[0093] It can be seen that the field-of-view hole 110 can be arranged on the first side wall 161, or the second side wall 162, or the transition zone of the first side wall 161 and the second side wall 162. Among them, in some wearing modes, the first side wall 161 is the part of the transition connecting wall 160 directly facing the front of the wearer, and if the field-of-view hole 110 is arranged on the first side wall 161, the arrangement of the field-of-view hole 110 can ensure that the camera 400 can capture the field of view in front of the wearer. Similarly, in another wearing mode, the second side wall 162 is the part of the transition connecting wall 160 directly facing the front of the wearer, and in still another wearing mode, the transition zone of the first side wall 161 and the second side wall 162 is the part of the support facing the front of the wearer. In this way, the blind area of the camera 400 can be reduced as much as possible, which is beneficial to the camera 400 to better obtain the image information in front of the wearer.

[0094] In addition, the optical axis can be arranged to deviate from the front of the wearer within a proper range, for example, the range can be -10°-10°, which helps to capture specific angles, especially when it is necessary to capture environmental information or take a slight overhead or upward shot, the wearer can adjust the wearing manner according to actual needs, which is not limited herein.

[0095] In the embodiment of the present application, referring to FIG. 4, the inner cavity of the first shell 100 includes a first chamber 120 and a second chamber 130, wherein the camera 400 is located in the first chamber 120, and the speaker unit 200 is located in the second chamber 130, along the coronal axis direction of the human body (i.e., the left-right direction of the human body), the first chamber 120 is located on the side away from the face of the second chamber 130.

[0096] In a specific implementation, the camera 400 is arranged in the first chamber 120, which ensures that the camera 400 does not affect the operation of other components and can stably and efficiently capture images. The first chamber 120 provides a containing space for the camera 400, so that the camera 400 is protected from external interference and damage.

[0097] For example, the speaker unit 200 is arranged in the second chamber 130, and the speaker unit 200 is located closer to the ear canal of the wearer to ensure clear transmission and high-quality playback of the audio signal. The second chamber 130 takes into account the propagation characteristics of sound and the comfort of wearing.

[0098] In terms of layout, along the coronal axis direction of the human body, the first chamber 120 is located on the side away from the face of the second chamber 130. Such arrangement is conducive to reducing the mutual interference between the camera 400 and the speaker unit 200 and ensuring the full play of their respective functions. In addition, the first chamber 120 is arranged on the side away from the face of the second chamber 130, so that the camera 400 can directly face the front field of view of the wearer and capture images of the front side of the face without obstruction, avoiding the occlusion of the camera 400 by the ear of the wearer, reducing the visual blind area caused by the face, and ensuring the maximization of the shooting range of the camera 400.

[0099] In the embodiment of the present application, the projection of the camera 400 on the sagittal plane of the human body at least partially overlaps the projection of the speaker unit 200 on the sagittal plane of the human body.

[0100] In this way, the camera 400 and the speaker unit 200 are relatively close in the front-back direction of the human body. In order to ensure the normal use of the camera 400 and the speaker unit 200, the camera 400 is located on the side away from the face relative to the speaker unit 200. Such arrangement is helpful to optimize the internal space of the earphone and ensure the maximization of the shooting range of the camera 400.

[0101] In the embodiments of the present application, in the wearing state, the second cavity 130 is located in the concha cavity, and at least part of the projection of the first cavity 120 on the sagittal plane of the human body is located in the concha cavity.

[0102] Specifically, the second cavity 130 is located in the concha cavity of the wearer. The concha cavity, as a recessed area of the ear, can provide a placement position for the loudspeaker unit 200, thereby ensuring that the loudspeaker unit 200 can be closely close to the ear canal of the wearer to provide clear and immersive audio experience, and also utilizes the spatial advantage of the ear structure to improve the comfort and stability of wearing.

[0103] In addition, in the wearing state, at least part of the first cavity 120 will be located in the projection range of the concha cavity when projected with the sagittal plane of the human body as the reference plane. In this way, it is ensured that the camera 400 has enough space for image capture, and the overall coordination and aesthetics during wearing are also taken into account. The internal space of the earphone is optimized, and the maximization of the shooting range of the camera 400 is ensured.

[0104] In the embodiments of the present application, in combination with FIGS. 7 and 8, the first shell 100 includes an inner side wall 140 facing the face along the coronal axis direction of the human body, and an outer side wall 150 facing away from the face, the outer side wall 150 including an extension region 151 extending away from the face along the coronal axis direction of the human body, the field-of-view hole 110 and the camera 400 being arranged on the extension region 151.

[0105] In specific implementation, the inner side wall 140 is arranged to face the face along the coronal axis direction of the human body, thereby ensuring comfortable fitting and appropriate distance feeling between the device and the face of the wearer.

[0106] The outer side wall 150 is provided with the extension region 151, which extends away from the face along the coronal axis direction of the human body. The field-of-view hole 110 and the camera 400 are arranged on the extension region 151, thereby optimizing the overall appearance of the earphone and ensuring that the camera 400 can capture high-quality images or videos without being disturbed or limited due to improper position. In this way, the wearing comfort of the wearer is ensured, and the multi-functionality is also improved.

[0107] In the embodiments of the present application, the extension region 151 is arranged opposite to the concha cavity of the human body along the coronal axis direction of the human body.

[0108] It should be noted that, through the opposite arrangement along the coronal axis direction of the human body, the extension region 151 can avoid the main structure of the ear and reduce the compression feeling on the ear of the wearer, thereby improving the overall wearing experience. In addition, in this way, the field-of-view hole 110 and the camera 400 are provided with more reasonable installation space, thereby further enhancing the practicality and functionality of the earphone.

[0109] In the embodiment of the present application, in the wearing state, the extension area 151 extends beyond the auricle along the human coronal axis direction.

[0110] Specifically, the extension area 151 extends beyond the auricle along the direction of the human coronal axis. In this way, the camera 400 can be installed so that it can directly face the front field of view of the wearer and capture images of the front side of the face without obstruction, thereby reducing the blind area caused by the face and ensuring the maximization of the shooting range of the camera 400.

[0111] In the embodiment of the present application, referring to FIG. 7, the extension area 151 also extends downward along the human vertical axis direction, and the extension area 151 includes a first end 1511 and a second end 1512 along the human vertical axis direction. In the human coronal axis direction, the distance between the second end 1512 and the face is greater than the distance between the first end 1511 and the face, and the camera 400 and the field-of-view hole 110 are both arranged at the second end 1512.

[0112] The first end 1511 serves as the upper part of the extension area 151 and is relatively close to the face, and the second end 1512 serves as the extended end of the extension area 151 and is significantly farther from the face in the human coronal axis direction. The camera 400 and the field-of-view hole 110 are both arranged at the second end 1512. In this way, the camera 400 can capture a wider field of view, which is conducive to improving the interactive experience of the earphone.

[0113] In the embodiment of the present application, the extension area 151 is connected to the part of the first shell 100 other than the extension area 151 in a circular arc transition manner.

[0114] The circular arc transition connection is conducive to improving the aesthetics of the earphone and can also improve the user experience from the functional point of view. It ensures the comfort of the wearer's hand or face when it contacts the earphone in different use scenarios, and avoids the discomfort caused by sharp corners.

[0115] In the embodiment of the present application, referring to FIGS. 3 and 4 and FIG. 9, the first shell 100 includes an inner side wall 140 facing the face along the human coronal axis direction, and the inner side wall 140 includes a first area that directly contacts the preauricular area of the wearer in the wearing state. The voice processing unit 500 is arranged in the first shell 100 at a position opposite to the first area.

[0116] In actual implementation, the first area is arranged on the inner side wall 140 and can directly contact the preauricular area of the wearer when the earphone is worn. In this way, the stability of the earphone during wearing is ensured, and in addition, the compression of other areas of the face is reduced, thereby improving the wearing experience of the wearer.

[0117] Further, a voice processing unit 500 is arranged inside the first shell 100 at a position opposite to the first area. In this way, the utilization of the internal space of the earphone is optimized, and the voice processing unit 500 can more accurately capture the sound signals emitted by the wearer, thereby improving the clarity and accuracy of voice interaction. In this way, the earphone provided in this embodiment can provide a convenient wearing experience and also realize efficient voice interaction function.

[0118] In this embodiment of the present application, in the wearing state, the first area is located in the preauricular region above the tragus.

[0119] When the earphone is stably worn on the ear of the wearer, the first area on the inner side wall 140 is located in the preauricular region above the tragus. This arrangement conforms to the ergonomic principle and also takes into account the comfort and stability of wearing. In addition, it can effectively reduce the direct pressure on the sensitive areas of the wearer's face, and also ensure that the earphone closely fits the contour of the ear during wearing, preventing discomfort caused by shaking or displacement.

[0120] In this embodiment of the present application, the voice processing unit 500 is configured to obtain the pronunciation state of the wearer of the earphone by detecting the vibration of the human head.

[0121] In actual implementation, since the preauricular region above the tragus is the skull vibration region during human pronunciation, the voice processing unit 500 in the first area can capture the vibration signals caused by the slight vibration of the head of the wearer of the earphone when the wearer uses the earphone for voice communication, and analyze and process these signals. In this process, the pronunciation state of the wearer of the earphone can be fed back in real time, and the background noise and effective voice can be effectively distinguished, thereby improving the accuracy and clarity of voice recognition.

[0122] In this embodiment of the present application, referring to FIGS. 3 and 8, the inner side wall 140 of the first shell 100 is provided with a relief portion 170 adapted to the concha cavity, and the relief portion 170 is located in the region between the camera 400 and the speaker unit 200 along the sagittal axis of the human body.

[0123] It should be noted that the concha cavity is a component of the external ear and is located below and in front of the pinna and is a relatively concave region. The relief portion 170 is concave, so that the relief portion 170 can be adapted to the concha cavity to provide a support point for the earphone. The concave design also reduces the feeling of oppression of the earphone on the concha cavity, thereby improving the comfort of wearing. In addition, the relief portion 170 is located in the region between the camera 400 and the speaker unit 200, so that when the earphone is worn, the relief portion 170 can be fitted below and in front of the concha cavity, thereby ensuring the stability of the device and also ensuring that the sound is accurately transmitted to the ear canal of the wearer.

Specifically, the first sound pickup hole 180 is arranged on the inner side wall of the first shell 100 and is arranged towards the front side of the face. In this way, it is ensured that the first sound pickup hole 180 can be close to the mouth area of the wearer, effectively capturing the sound emitted by the wearer, reducing the noise interference of the surrounding environment, and improving the clarity and accuracy of voice recording.

[0126] Among them, the first sound pickup hole 180 can be provided with two, in this way, the voice capture effect can be improved, of course, the present embodiment does not limit here.

[0127] In addition, the second sound pickup hole 190 is located on the outer side wall 150 of the first shell 100, and the second sound pickup hole 190 further widens the collection range of sound, and can capture sound information from different directions. Through the cooperation of the first sound pickup hole 180 and the second sound pickup hole 190, the earphone in the embodiment of the present application can realize omnidirectional and high-precision sound acquisition, and bring the wearer a more natural and smooth voice interaction experience.

[0128] In the embodiment of the present application, referring to FIG. 5 and FIG. 9, the sound generating part 10 further comprises a mainboard 600 and an image processor 700. Along the coronal axis direction of the human body, the image processor 700 is located on the side of the mainboard 600 facing the human body.

[0129] Among them, the mainboard 600 is used to process various signals and data, is responsible for coordinating the work between various components, and ensures the stable operation of the whole system.

[0130] Further, along the coronal axis direction of the human body (i.e. the left-right direction of the human body), the image processor 700 is located on the side of the mainboard 600 facing the human body. The image processor 700 is used to process image information. In this way, the image processor 700 and the camera 400 can work together to provide users with more rich and intuitive information interaction experience.

[0131] In the embodiment of the present application, the earphone can further include a communication module 900 located in the first shell 100, the communication module is electrically connected with the camera 400 and wirelessly transmits the image captured by the camera 400 to an external device.

[0132] It should be noted that the camera 400 is electrically connected with the communication module 900, and the camera 400 is configured to be able to take pictures of the area in front of the face when the earphone is in the wearing state, and send the image or video captured by the camera 400 to an external device such as a mobile phone, a tablet computer, etc. through the communication module 900. In this way, the communication module 900 enables the earphone to directly transmit data with the external device, so as to meet the use demand of the user and improve the user experience.

[0133] In addition to the earphone provided with the voice processing unit 500 in the above-mentioned embodiment, the present application also provides an earphone provided with a communication module 900. Of course, it can be understood that the earphone of the present application can be provided with both a voice processing unit and a communication module. The earphone provided with the communication module 900 will be described in detail below.

[0134] Referring to FIGS. 13-16 and 10-12, the earphone of the present application can include a sound generating part 10 provided on the front side of the ear, a main body part 20 provided on the back side of the ear, and an ear hook part 30 connecting the sound generating part 10 and the main body part 20. The reasonable arrangement of the sound generating part 10, the main body part 20 and the ear hook part 30 ensures the stability and comfort of the earphone when worn, and also ensures the balance of the center of gravity of the earphone on the front side and the back side of the ear.

[0135] The sound generating part 10 includes a first shell 100, and a speaker unit 200, a microphone unit 300, a camera 400 and a communication module 900 arranged in the inner cavity of the first shell 100. In this way, the sound generating part 10 includes multiple kinetic energy, including but not limited to sound generation, sound collection, image capture, communication, realizing the integration of multiple functional modules at the sound generating part 10, making the earphone function comprehensive, and also making the overall structure of the earphone compact, improving the portability of the earphone. In addition, the sound generating part 10 is arranged on the front side of the ear, which can ensure good acoustic effect.

[0136] The first shell 100 is provided with a view hole 110, which can be circular, square, oval or any other shape, and the embodiment is not limited in this regard. The camera 400 is arranged at the view hole 110, so that the earphone can directly capture the area in front of the user's face through the view hole 110 when worn, and obtain image or video information in the user's line of sight. For example, in combination with FIGS. 13 and 14, the camera 400 has a wider line of sight range than the human body, which ensures the comprehensiveness of information capture.

[0137] The camera 400 is electrically connected to the communication module 900, and the camera 400 is configured to capture the area in front of the face when the earphone is in a worn state, and transmit the image or video captured by the camera 400 to an external device through the communication module 900. It can be seen that the communication module 900 enables the earphone to directly transmit data with the external device without relying on a smart phone as a transit station, thereby improving the efficiency and stability of data transmission.

[0138] By integrating the camera 400, the microphone unit 300, the speaker unit 200 and the communication module 900 in the sound generating part 10, and connecting the ear hook part 30 between the sound generating part 10 and the main body part 20, the earphone has independent camera and communication capabilities, and the user can realize AI interaction anytime and anywhere in the worn state as needed, thereby simplifying the cumbersome steps of connecting the traditional earphone and the smart phone through Bluetooth and then transmitting data, and improving the user's convenience.

[0139] In addition, compared with the traditional smart glasses and smart watches, the earphone design in the embodiment of the application places the sound generating part 10 on the front side of the ear, the main body part 20 on the rear side of the ear, and connects them through the ear hook part 30, forming a stable wearing structure that does not put pressure on the nose bridge and does not affect the use of the camera due to wrist shaking, thereby improving the wearing comfort and convenience.

[0140] For example, the earphone of the embodiment of the application can be used in daily office work, remote conference, online education, field hiking and the like.

[0141] Optionally, the camera 400 in the earphone of the embodiment can also be provided with privacy protection to control the opening and closing time of the camera, and limit the range and object of data transmission, thereby ensuring the privacy and safety of the user.

[0142] Optionally, in combination with FIG. 13 and FIG. 14, the microphone unit 300 can include a plurality of microphones arranged in an array, for example, the plurality of microphones can be arranged in a ring array, a rectangular array, a circular array or other shaped array. The microphone unit 300 is arranged on the side of the speaker unit 200 away from the human body, and the microphone array captures sound from the direction of the human face, such as the user's voice command or environmental sound, through the cooperation of the plurality of microphone units 300, to improve the accuracy and clarity of sound collection.

[0143] In some embodiments, in combination with FIG. 10 to FIG. 12, the camera 400 has an optical axis, for example, the camera 400 has a plurality of lenses arranged in a predetermined direction, each lens can be set as a convex lens, a concave lens as needed, and the optical axis here refers to the optical axis of the plurality of lenses, the extension direction of the optical axis is consistent with the arrangement direction of the plurality of lenses. When the earphone is in a wearing state, the optical axis has an included angle with the horizontal direction, and the value of the included angle can be -20° to 20°. For example, the included angle can be -20°, -15°, -10°, 0°, 5°, 15°, etc. Within the range of the included angle, the camera 400 can capture the area directly in front of the user's head and slightly upward or downward, and the optical axis can change with the movement of the user's head, so as to ensure the convenience of the user when viewing the surrounding environment or performing overhead shooting or downward shooting.

[0144] In some embodiments, in combination with FIG. 10 and FIG. 11, the field of view hole 110 is on the side of the first shell 100 facing the front of the ear, or the field of view hole 110 is located on the side of the first shell 100 facing away from the human face, so that the field of view of the camera 400 directly points to the front of the user, facilitating the capture of the user's gestures and the environmental information in front of the user, and avoiding the occlusion of the camera by the user's ear, reducing the field of view blind area caused by the human face, and ensuring the maximization of the shooting range of the camera 400. For example, the field of view blind area is 0-20cm. It should be noted that the earphone is worn after the hair in front of the ear is arranged to avoid occlusion of the camera 400 and ensure the clarity of the image.

[0145] In addition, in combination with FIG. 12, the wearing of the left and right earphones can ensure that the left and right ears of the user are respectively provided with the camera 400. In some embodiments, the normal field of view of the human eye is the first field of view 410, and the field of view of the camera 400 is the second field of view 420. When the earphone is worn, the second field of view 420 can cover the first field of view 410. For example, the camera 400 can be configured as a wide-angle lens or an adjustable angle configuration to ensure that if the earphone is tilted during wearing, the second field of view 420 of the camera 400 can still cover the first field of view 410 of the human eye.

[0146] In some embodiments, in combination with FIG. 15 and FIG. 16, the first shell 100 includes an inner side wall 120 facing the user's face along the coronal axis direction of the human body (i.e. the left-right direction of the human body), which is in close contact with the user's ear or head to provide stable wearing support, and an outer side wall 130 facing away from the user's face, and a transition connecting wall 140 connecting the inner side wall 120 and the outer side wall 130 to form a relatively closed inner cavity. The field of view hole 110 is provided in the area of the transition connecting wall 140 facing forward of the user's face.

[0147] In this way, the lens of the camera 400 can be directly aimed at the front of the user, including the user's gesture and the environment in front of the user, ensuring the camera range and image quality of the camera 400, and also making the earphone as a whole simple and beautiful.

[0148] In some embodiments, in combination with FIG. 16, the transition connecting wall 140 can include a first side wall 161, a second side wall 162, a third side wall 163 and a fourth side wall 164 connected in sequence, the first side wall 161 and the third side wall 163 are oppositely arranged, the second side wall 162 and the fourth side wall 164 are oppositely arranged, and the first side wall 161 and the second side wall 162 are both facing forward of the user's face, and the field of view hole 110 is provided in one of the first side wall 161, the second side wall 162 and the transition region of the first side wall 161 and the second side wall 162.

[0149] It can be seen that the field of view hole 110 can be provided on the first side wall 161, or the second side wall 162, or the transition region of the first side wall 161 and the second side wall 162. Among them, in some wearing modes, the first side wall 161 is the part of the transition connecting wall 140 directly facing the front of the user, and if the field of view hole 110 is provided on the first side wall 161, the setting of the field of view hole 110 can ensure that the camera 400 can capture the field of view in front of the user. Similarly, in other wearing modes, the second side wall 162 is the part of the transition connecting wall 140 directly facing the front of the user, and in still other wearing modes, the transition region of the first side wall 161 and the second side wall 162 is the part of the bracket facing the front of the user. In addition, in addition to directly facing the front of the user, the optical axis can also be set to deviate from the front of the user within a suitable range, for example, the range can be -10°-10°, which is helpful to capture specific angles, especially when it is necessary to capture environmental information or take a slight overhead or overhead shot, the user can adjust the wearing mode according to the actual needs, which is not limited here.

[0150] In some embodiments, as shown in FIGS. 13 and 14, the communication module 900 is arranged on the side of the speaker unit 200 away from the face of the user in the direction of the coronal axis of the human body. The communication module 900 generates heat during operation. Arranging the communication module 900 on the side of the speaker unit 200 away from the face of the user can reduce the impact of heat on the user and improve the comfort of use of the earphone.

[0151] In some embodiments, as shown in FIG. 13, the inner side wall 120 of the first housing 100 is provided with a recess 170 adapted to the concha cavity. The concha cavity is a part of the external ear and is located in the lower front of the auricle. The recess 170 is concave. In this way, the recess 170 can be adapted to the concha cavity to provide a support point for the earphone. The concave design can reduce the pressure of the earphone on the concha cavity and improve the comfort of wearing. In addition, the recess 170 is located in the area close to the end of the sound generating part 10 of the inner side wall 120. In this way, the earphone can be fitted to the lower front of the concha cavity when worn, thereby ensuring the stability of the device and ensuring that the sound is accurately transmitted to the ear canal of the user. In addition, the interference of external noise is reduced, and the sound quality of the earphone is improved.

[0152] In some embodiments, as shown in FIG. 13, the first housing 100 is provided with a sound pickup hole and a sound outlet hole. At least one of the sound pickup hole and the sound outlet hole is in the recess 170.

[0153] For example, if the sound pickup hole is arranged in the recess 170, the microphone or other sound pickup element can be placed in a relatively concealed position and can capture sound well. The interference of external noise is reduced, and the clarity of sound pickup is improved.

[0154] In addition, if the sound outlet hole is arranged in the recess 170, it is ensured that the sound in the earphone is directly and accurately transmitted to the ear canal of the user, the interference of external noise is reduced, the sealing when worn is improved, sound leakage is prevented, and the sound quality of the earphone is enhanced.

[0155] Furthermore, if the sound pickup hole or the sound outlet hole or both are integrated in the recess 170, the internal space of the earphone can be effectively utilized, the compactness of the earphone as a whole is ensured, the clarity of sound pickup is improved, the sound quality of the earphone is enhanced, and a good user experience is ensured.

[0156] In some embodiments, in combination with FIGS. 13 and 14, the communication module 900 can be an eSIM card or other communication-capable device. The communication module 900 includes a module body 910 and a communication antenna 920 located on the side of the module body 910 facing away from the speaker unit 200. Specifically, the communication antenna 920 generates electromagnetic waves when in operation. By locating the communication antenna 920 on the side facing away from the speaker unit 200, the electromagnetic interference of the communication antenna 920 on the speaker unit 200 is reduced, ensuring the clarity of the sound. In addition, the location of the communication antenna 920 will affect its signal receiving and transmitting capabilities to some extent. By locating the communication antenna 920 on the side facing away from the speaker unit 200, i.e., on the side facing away from the human body, the influence of the human body and other factors on signal transmission is reduced, which helps the communication antenna 920 to capture and transmit signals, improving the stability and reliability of communication.

[0157] In some embodiments, in combination with FIGS. 13 and 14, the first housing 100 includes a first bottom shell 191 and a first upper shell 192. In this way, by combining the first bottom shell 191 and the first upper shell 192 into the first housing 100, a double-layer design of the first housing 100 is achieved, improving the structural stability and helping to resist external impact and pressure. The first bottom shell 191 is located on the side of the first upper shell 192 facing the human face. Optionally, the shape of the first bottom shell 191 is designed to match the facial contour of the human face. In this way, when the earphone is worn, the first bottom shell 191 will fit the facial contour of the user, improving the comfort and stability of wearing. The communication antenna 920 is fixedly connected to the first upper shell 192. In this way, it helps to reduce the direct contact of the communication antenna 920 with the human body and other factors, reducing the risk of signal attenuation and interference and ensuring communication quality.

[0158] In addition, by placing the communication antenna 920 on the first upper shell 192, the internal space of the earphone can be fully utilized to reduce unnecessary space waste and enhance the overall compactness of the earphone. In addition, by placing the communication antenna 920 on the first upper shell 192, the heat dissipation of the communication module 900 is facilitated, the temperature inside the earphone is reduced, and the user experience of the earphone is improved.

[0159] In some embodiments, in combination with FIGS. 13 and 14, the communication antenna 920 is integrally formed with the first upper shell 192. In this way, the connecting components between the communication antenna 920 and the first upper shell 192 are reduced, ensuring the overall compactness of the earphone. In addition, integrally forming ensures the connection stability between the communication antenna 920 and the first upper shell 192, reducing the risk of the communication antenna 920 loosening or falling off due to poor connection.

[0160] In some embodiments, as shown in FIGS. 13 and 14, the communication antenna 920 is arranged on a flexible circuit board, the flexible circuit board is fixedly connected with the first upper shell 192, and the flexible circuit board has a certain flexibility and can be appropriately bent according to the internal space of the first shell 100, so as to ensure the space utilization rate of the earphone. If the communication antenna 920 or the circuit board fails, it can be replaced alone, thereby reducing the maintenance cost. In addition, the flexible circuit board can provide a stable signal transmission path and ensure the transmission quality of the signal.

[0161] The above two arrangement methods of the communication antenna 920 can be selected according to actual conditions, and are not limited herein. For example, if the earphone type has high requirements for structural compactness and stability, the one-piece forming mode is recommended. If the earphone type requires flexibility or customizability of the structure, or has high requirements for signal transmission quality, the mode of the flexible circuit board is recommended.

[0162] In some embodiments, as shown in FIGS. 13 and 14, the communication module 900 is an LTE module. Specifically, the LTE module supports network connection, ensures that the images or videos captured by the camera 400 are stably transmitted to external devices such as cloud servers, and the like, thereby ensuring the flexibility and convenience of the earphone in the field of wireless communication. For example, the module main body 910 can be an LTE module, and the communication antenna 920 can be an LTE antenna.

[0163] In some embodiments, as shown in FIGS. 13 and 16, the ear hook part 30 includes a deformed support 310 and a soft rubber piece 320 wrapped outside the deformed support 310. The deformed support 310 is the skeleton of the ear hook part 30, provides strength and stability, ensures that the earphone can fit the ear of the user when worn, and is not easy to fall off. In addition, the deformed support 310 also has deformability, and the user can freely adjust according to the wearing situation of the user, thereby improving the wearing flexibility of the earphone. For example, the deformed support 310 can be made of lightweight and high-strength metal materials or alloys, such as titanium alloy, aluminum alloy, high-strength steel, and the like.

[0164] In addition, the soft rubber piece 320 is wrapped outside the deformed support 310 and serves as a comfort layer of the ear hook part 30, thereby playing a buffering role. The soft rubber piece 320 disperses the pressure of the earphone on the ear, thereby reducing the discomfort caused by long-term wearing.
