The camera hole is arranged in the first shell and communicates with the first shell. The camera unit is arranged in the first shell. The camera unit is configured to acquire images and / or videos in an external environment through the camera hole. In this way, the earphone has a shooting function in addition to the functions of listening to music or talking, thereby improving the functional diversity of the earphone.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor are within the scope of protection of the present disclosure.

[0044] The earphone 100 provided by the embodiments of the present disclosure can be an in-ear earphone, a semi-in-ear earphone, a bone conduction earphone, a wireless earphone, etc. The embodiments of the present disclosure are described below taking a wireless earphone as an example.

[0045] In order to clearly describe the structure of the earphone provided by the present disclosure, the structure of the ear and the wearing state, the front side, the back side, the upper side, the lower side of the ear, the sagittal plane, the coronal plane, the horizontal plane, the sagittal axis, the coronal axis, the vertical axis, and the definitions of the X, Y, and Z directions will be described below.

[0046] Please refer to FIG. 1 and FIG. 2, the ear 200 of a user includes a helix 210, a concha 220, a tragus 230, an antitragus 240, an antihelix 250, an upper antihelix crus 251, a lower antihelix crus 252, a triangular fossa 260, a helix crus 270, an ear canal opening 280, an earlobe 290, etc. The concha 220 can include a concha cymba 222 and a concha cavity 221.

[0047] The front side and the back side of the ear are defined as follows: The “front side of the ear” in the present disclosure is a concept relative to the “back side of the ear”, the former refers to the side of the ear away from the head, and the latter refers to the side of the ear towards the head.

[0048] The sagittal plane, the coronal plane, the horizontal plane, the sagittal axis, the coronal axis, and the vertical axis of the human body are defined as follows: As is well known, in the fields of medicine, anatomy, etc., the sagittal plane, the coronal plane, and the horizontal plane of the human body can be defined as three basic planes, and the sagittal axis, the coronal axis, and the vertical axis can be defined as three basic axes. The sagittal plane refers to a plane perpendicular to the ground made along the front-to-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground made along the left-to-right direction of the body, which divides the human body into front and back parts; and the horizontal plane refers to a plane parallel to the ground made along the up-to-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis perpendicular to the coronal plane along the front-to-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane along the left-to-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane along the up-to-down direction of the body. The direction parallel to the sagittal axis is the X direction; the direction parallel to the coronal axis and pointing to the outside of the ear is the Y direction; and the direction parallel to the vertical axis is the Z direction.

[0049] Please refer to FIG. 3 to FIG. 5, the earphone 100 provided by the embodiment of the present disclosure includes an earphone head 110 and an ear clip 120, the earphone head 110 and the ear clip 120 are connected to each other and jointly form a clamping to the antihelix, so that the earphone 100 can be worn on the ear of the user.

[0050] In the wearing state, the earphone head 110 is located at the front side of the ear 200 and extends towards the concha cavity 221, so that the sound producing component of the earphone 100 is close to the concha cavity 221, and the sound quality effect of the earphone is improved. It should be noted that the sound quality effect in the embodiment includes the volume of the earphone and the clarity of the sound quality of the earphone.

[0051] The ear clip 120 bypasses the area opposite to the concha cavity 221 of the antihelix 210, so that the end of the ear clip 120 away from the earphone head 110 is located at the back side of the ear 200, so that the earphone 100 in the embodiment is in the form of an ear clip.

[0052] Please refer to FIG. 4, wherein the earphone head 110 includes a first shell 111, and the inner cavity of the first shell 111 is used to set the components of the earphone 100, for example, the inner cavity of the first shell 111 can be used to set the sound producing device, the microphone or other components.

[0053] The earphone head 110 further includes a camera hole 112 and a camera unit 113, the camera hole 112 is arranged on the first shell 111 and communicates with the inner cavity of the first shell 111, so that the camera hole 112 is a through hole penetrating along the thickness direction of the first shell 111. The camera hole 112 can be circular, square, oval or any other shape, and the embodiment does not limit this.

[0054] It should be noted that a waterproof light transmission film can also be arranged on the camera hole 112, so that the camera unit 113 can capture clear and bright images and videos, and water can be effectively prevented from entering the inside of the earphone head 110, thereby protecting the camera unit 113 and other internal electronic elements from water damage and improving the service life of the earphone 100.

[0055] The camera unit 113 is arranged in the first housing 111, and the camera unit 113 is configured to acquire images and / or videos in the external environment through the camera hole 112. In this way, the earphone can have a shooting function while ensuring the functions of listening to music or making a call, thereby improving the functional diversity of the earphone and the use flexibility of the earphone. For example, when the user wears the earphone to go outdoors, the earphone 100 can record the surrounding environment by means of the camera unit 113. The earphone 100 can also interact with external devices according to the surrounding environment photographed by the camera unit 113 to judge the photographed surrounding environment, thereby improving the safety of the user. For another example, when the user wears the earphone in a remote meeting, the earphone 100 can capture the user's voice and gesture information to provide accurate instruction input for AI.

[0056] The earphone provided by the embodiments of the present disclosure can be used to acquire images and / or videos of the side and / or front of the user in the wearing state. In some embodiments, in the wearing state and along the direction of the human sagittal axis, the first housing 111 includes oppositely arranged first and second wall surfaces 1111 and 1112, and the second wall surface 1112 faces the concha cavity 221; or in other words, along the direction of the human sagittal axis, the first wall surface 1111 is a wall surface facing the front of the user, and the second wall surface 1112 is a wall surface facing the back of the user.

[0057] The camera hole 112 is arranged on the first wall surface 1111 and penetrates the first wall surface 1111; and the camera unit 113 is arranged on the side of the first wall surface 1111 facing the inner cavity of the first housing 111 and is arranged at the camera hole 112. In this way, the earphone can directly capture the area in front of the user's face through the camera hole 112 in the wearing state, and further acquire image and / or video information in the user's line of sight direction.

[0058] In other embodiments, the camera unit 113 can also be arranged on the side of the second wall surface 1112 facing the inner cavity of the first housing 111 and opposite the camera hole 112. In this way, the arrangement position of the camera unit 113 can be flexibly adjusted according to the layout of various components in the first housing 111, thereby improving the design flexibility of the earphone 100.

[0059] As for the selection of the setting position of the camera hole 112 on the first wall surface 1111, the camera hole 112 can be as far away from the tragus of the ear 200 as possible to avoid the occlusion of the camera unit 113 by the face region near the tragus. Exemplarily, the camera hole 112 is close to the connection region of the first wall surface 1111 and the ear clip 120. It should be noted that the connection region in the embodiment can be understood as the interface where the first wall surface 1111 connects and contacts with the ear clip 120, and the camera hole 112 close to the connection region of the first wall surface 1111 and the ear clip 120 can take the interface as the boundary, and the camera hole 112 has a preset distance from the boundary. In this way, on the one hand, the field of view of the camera unit 113 can be directly aligned with the front of the user, which is convenient for capturing the user's gestures or the environmental information in front of the user, and avoids the occlusion of the camera by the user's ear, and also reduces the visual blind area caused by the human face, thereby ensuring the maximization of the shooting range of the camera unit 113 and the image quality. On the other hand, it can also help to optimize the spatial layout in the first shell 111, so that the camera unit 113 and other components are more compactly integrated in the first shell 111.

[0060] In some embodiments, the camera unit 113 has an optical axis. The optical axis can be understood as the lens center of the camera unit 113 and a virtual straight line perpendicular to the imaging plane of the image sensor. Alternatively, the optical axis is the symmetry axis of the camera unit 113.

[0061] In the wearing state of the earphone, the included angle between the optical axis and the human sagittal plane is -20°-5°, and / or the included angle between the optical axis and the human horizontal plane is -10°--35°. Exemplarily, the included angle between the optical axis and the human sagittal plane can be -20°, -15°, -10°, -5°, 0° and 5°. The included angle between the optical axis and the human horizontal plane can be -10°, -15°, -20°, -25°, -30° and -35°.

[0062] By setting the included angle between the optical axis and the human sagittal plane and / or the included angle between the optical axis and the human horizontal plane, the shooting angle of the camera unit 113 can be optimized to be more in line with the ergonomic design. In this way, when wearing the earphone 100, the surrounding environment in the line-of-sight direction of the user can be captured more naturally, and the shooting blind area of the camera unit 113 is reduced as much as possible, thereby ensuring that the camera unit 113 can cover a wider field of view.

[0063] In some embodiments, the earphone 100 further comprises a voice processing unit 130, and the voice processing unit 130 is arranged in the first shell 111.

[0064] In the wearing state, the area of the first shell 111 opposite to the voice processing unit 130 is in contact with the inner wall of the concha cavity 221; based on the fact that sound can pass through the skull of the head as a transmission medium, the voice processing unit 130 is used to receive the bone-conducted voice signal. When the user is in a strong noise environment, the voice processing unit 130 can more clearly and accurately pick up the voice signal, because the bone-conducted voice signal is less affected by environmental noise. In this way, the user can communicate with others with a smaller voice, improve the privacy of the earphone, and enable the user to have private voice communication in public places or noisy environments.

[0065] In addition, the voice processing unit 130 can also cooperate with the microphone of the earphone 100, wherein the microphone of the earphone 100 receives the voice signal transmitted through the air, and the voice processing unit 130 receives the voice signal transmitted by bone conduction. By comparing the above two voice signals, if the two voice signals have high consistency in time and frequency, it can be judged that the user is speaking, otherwise it can be judged that the user is not speaking. At this time, the microphone can be automatically turned off when the user does not speak, enhancing user privacy protection, which is particularly important in some sensitive scenarios.

[0066] It should be understood that the voice processing unit 130 receives the voice signal transmitted by bone conduction, so it is better to be closer to the face. Please refer to FIG. 4, exemplarily, the earphone head 110 includes a protruding part 114 protruding towards the concha cavity 221, and the voice processing unit 130 is arranged in the cavity enclosed by the protruding part 114 and the earphone head 110. For example, part of the first shell 111 protrudes towards the concha cavity 221 to form the protruding part 114, that is, part of the second wall surface 1112 protrudes towards the concha cavity 221 to form the protruding part 114. In this way, the first shell 111 and the protruding part 114 can be an integral piece, which can simplify the manufacturing process, reduce manufacturing cost and assembly complexity. In addition, the design of the protruding part 114 can be adjusted according to the ear contour of the user, so that the earphone is more suitable for individual characteristics, and the beauty and individuality of wearing are enhanced. At the same time, this design also provides more design space for the earphone to meet the aesthetic needs of different users.

[0067] In the wearing state, the protruding part 114 is located in the concha cavity 221 and in contact with the inner wall of the concha cavity 221. In this way, the voice signal transmitted by bone conduction can be more effectively received, reducing the attenuation and interference of the signal in the transmission process, and improving the clarity and sensitivity of the voice signal.

[0068] In some embodiments, referring to FIG. 6, the earphone 100 further comprises a control unit 180 connected with the voice processing unit 130 and the camera unit 113, respectively, and the control unit 180 is configured to form an instruction for controlling the camera unit 113 according to the voice signal of the voice processing unit 130.

[0069] The camera unit 113 can take photos or videos of the surrounding environment of the user when needed, but if the camera unit 113 is always in an activated state when the function is not needed, the power consumption of the earphone 100 will be increased and the standby time of the earphone 100 will be reduced. Therefore, the linkage between the voice processing unit 130 and the camera unit 113 can be realized by the control unit 180 in the present embodiment, and the activation and deactivation of the camera unit 113 can be controlled by voice, so as to avoid the continuous operation of the camera unit 113 when it is not needed, thereby significantly reducing the overall power consumption of the earphone 100. This intelligent energy-saving mechanism can prolong the standby time and continuous use time of the earphone and improve the user experience.

[0070] In other embodiments, the images and / or videos obtained by the camera unit 113 need to be transmitted to an external electronic device for processing, for example, to a mobile phone or a computer. Therefore, the earphone provided in the present embodiment further comprises a communication module, and the camera unit 113 is connected with the external electronic device through the communication module, without relying on Bluetooth to realize the cumbersome steps of connecting the traditional earphone with the smart phone and then transmitting data, thereby improving the user's convenience.

[0071] In a possible implementation manner, the ear clip 120 comprises a first ear clip 121 and a second ear clip 122, the first ear clip 121 crosses the helix and connects the earphone head 110 and the second ear clip 122, and the second ear clip 122 extends along the contour of the back of the helix 210 and contacts the back of the ear.

[0072] The first ear clip 121 connects the second ear clip 122 and the earphone head 110, so that the earphone 100 forms a U-shaped structure, and the earphone 100 with the U-shaped structure has good stability and can be more effectively fitted to the contour of the user's ear, especially when the second ear clip 122 extends along the contour of the back of the helix 210 and contacts the back of the ear, which greatly increases the stability of the earphone wearing and reduces the risk of accidental falling of the earphone during movement or activity.

[0073] The design of the first ear clip 121 also increases the area of the region where the earphone crosses the helix, so that the parts of the earphone 100 can be arranged at the first ear clip 121 in a targeted manner, thereby improving the compactness of the layout of the earphone 100. For example, the first ear clip 121 comprises a second housing, and a circuit board 140 is arranged in the second housing; the circuit board 140 is connected with the camera unit 113 and the voice processing unit 130, respectively.

[0074] The camera unit 113 and the voice processing unit 130 are arranged in the first shell 111, and the circuit board 140 is arranged in a second shell adjacent to the first shell 111, thereby shortening the distance between the camera unit 113 and the voice processing unit 130 and the circuit board 140, helping to shorten the circuit layout between the circuit board 140 and the camera unit 113 and between the circuit board 140 and the voice processing unit 130, thereby shortening the signal transmission path, reducing signal attenuation and interference, optimizing data transmission efficiency and signal quality, and improving the overall performance of the earphone.

[0075] In other embodiments, the second ear hook 122 can be made of a hard material or an elastic material. For example, the second ear hook 122 is a bracket made of an elastic material. The elastic material can include silicone, thermoplastic polyurethane (TPU), or memory titanium wire, so that the user can adaptively adjust according to different wearing habits, ensure that the earphone is firmly fitted to the user's ear when worn, and reduce the risk of the earphone falling off.

[0076] In addition, the second ear hook 122 made of silicone or thermoplastic polyurethane (TPU) can also provide the user with a comfortable wearing touch and effectively disperse the pressure of the earphone on the ear, reducing the discomfort caused by long-term wearing.

[0077] In a possible implementation, the earphone 100 further includes a touch unit 170 arranged on the circuit board 140 and attached to the wall surface of the second shell away from the ear 200. The addition of the touch unit 170 enables the user to control the earphone 100 through simple touch operations, such as adjusting the volume, switching the audio, starting / stopping the camera, etc. The attachment of the touch unit 170 to the wall surface of the second shell away from the ear 200 can improve the touch sensitivity of the touch unit 170.

[0078] In a possible implementation, the second ear hook 122 includes a third shell in which a battery 150 is arranged, and the battery 150 is electrically connected to the circuit board 140, the camera unit 113, and the voice processing unit 130, respectively. The battery 150 provides power for the circuit board 140, the camera unit 113, and the voice processing unit 130, respectively, helping to ensure the stable operation and optimal performance of each functional module (such as the camera unit, the voice processing unit, etc.) of the earphone.

[0079] It should be noted that the cross-sectional area of the first ear clip 121 and the second ear clip 122 can be equal everywhere, or other options can also be selected. As an example, the cross-sectional area of the second ear clip 122 is greater than that of the first ear clip 121, so that the second ear clip 122 can provide a larger support area and stronger clamping force when in contact with the back of the ear, thereby enhancing the overall wearing stability of the earphone, which helps to reduce the risk of accidental falling of the earphone when the user is moving or active.

[0080] In addition, the provision of the second ear clip 122 helps to further optimize the weight distribution of the earphone 100. By concentrating part of the weight at the position of the back of the ear, the pressure of the earphone on the helix and the ear canal can be reduced, making the wearing more comfortable and natural, especially suitable for users who need to wear the earphone for a long time.

[0081] In a possible implementation, the earphone 100 further comprises a sound emitting part 160, which is arranged on the side of the earphone head 110 facing the concha cavity 221; in the direction of the human coronal axis, the sound emitting part 160 is arranged in a stack with the second wall surface 1112 of the earphone head 110. In this way, the space utilization is effectively improved, and this design can make the overall size of the earphone head 110 and the sound emitting part 160 smaller, thereby making the entire earphone smaller and more portable and lightweight, and facilitating the wearing of the earphone by people with smaller ears, and improving the application range of the earphone.

[0082] In addition, in the direction of the human coronal axis, the sound emitting part 160 is arranged in a stack with the second wall surface 1112 of the earphone head 110, which can also help the sound emitting part 160 to extend into the concha cavity 221, and thereby make the sound emitting part 160 closer to the ear canal opening 280, and improve the performance effect of the sound quality and volume of the earphone 100.

[0083] In some embodiments, the sound emitting part 160 is arranged in the first shell 111, at this time, part of the area of the second wall surface 1112 of the first shell 111 protrudes towards the concha cavity 221, so that the second wall surface 1112 forms a containing cavity, which is in communication with the inner cavity of the first shell 111. The sound emitting part 160 is arranged in the containing cavity. Since the containing cavity is closer to the ear canal opening, it can help to promote the natural conduction of audio, reduce attenuation and distortion, and make the audio more real and natural.

[0084] In the present embodiment, the wall surface opposite to the sound emitting part 160 of the first shell 111 is provided with a sound outlet hole. The sound outlet hole is in communication with the inner cavity of the first shell 111, and the audio formed by the sound emitting part 160 can be transmitted to the ear canal opening of the ear through the sound outlet hole.

[0085] It should be noted that when the first shell 111 includes the accommodating chamber, the sound outlet hole can be arranged on the bottom wall and / or the side wall of the accommodating chamber. The present embodiment can ensure that the sound enters the ear canal at the optimal angle and in the optimal manner by ingeniously arranging the sound outlet hole at the appropriate position of the first shell (such as the bottom wall or the side wall of the accommodating chamber), thereby reducing the discomfort caused by the sound directly impacting the eardrum.
