Detailed Implementation

[0050] Headphones are devices that convert electrical signals into sound, typically used for personal audio listening or calls. 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. However, they have a relatively limited functionality.

[0051] To address the aforementioned technical problems, this application provides an earphone. The earphone head includes a first housing, a camera hole, and a camera unit. The camera hole is disposed within the first housing and communicates with it. The camera unit is disposed within the first housing and configured to acquire images and / or videos of the external environment through the camera hole. This allows the earphone to perform music listening or call functions while also possessing a shooting function, thus improving the earphone's functional versatility.

[0052] 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.

[0053] This application provides an earphone 100, which can be an in-ear earphone, a semi-in-ear earphone, a bone conduction earphone, a wireless earphone, etc. The following description uses a wireless earphone as an example to illustrate this application embodiment.

[0054] To facilitate a clear description of the structure of the headphones provided in this application, the following will explain the structure of the ear and the wearing states mentioned herein, the definitions of the front, back, upper, and lower sides of the ear, the sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, vertical axis, and the X, Y, and Z directions of the human body.

[0055] Please refer to the attached document. Figure 1 and attached Figure 2 The user's ear 200 includes structures such as the helix 210, concha 220, tragus 230, antitragus 240, antihelix 250, superior crus of antihelix 251, inferior crus of antihelix 252, triangular fossa 260, crus of helix 270, ear canal opening 280, and earlobe 290. The concha 220 may include the cymba conchae 222 and the conchae cavity 221.

[0056] The front and back sides of the ear are defined as follows: In this invention, "front side of the ear" is a concept relative to "back side of the ear". The former refers to the side of the ear that is away from the head, while the latter refers to the side of the ear that faces the head.

[0057] The sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and vertical axis of the human body are defined as follows: As is well known in medicine, anatomy, and other fields, the human body has three basic planes: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Specifically, the sagittal plane is a plane perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts; the coronal plane is a plane perpendicular to the ground along the left and right direction of the body, dividing the body into anterior and posterior parts; and the horizontal plane is a plane parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis perpendicular to the coronal plane along the anteroposterior direction of the body; the coronal axis is the axis perpendicular to the sagittal plane along the left and right direction of the body; and the vertical axis is the axis perpendicular to the horizontal plane along the vertical direction of the body. The X direction is defined as the direction parallel to the sagittal axis; the Y direction is defined as the direction pointing outward from the ear and parallel to the coronal axis; and the Z direction is defined as the direction parallel to the vertical axis.

[0058] Please refer to the attached document. Figure 3 To be continued Figure 5 The earphone 100 provided in this application embodiment 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 together clamp the ear helix so that the earphone 100 can be worn on the user's ear.

[0059] When worn, the earphone head 110 is located in front of the ear 200 and extends towards the concha 221, so that the sound-producing component of the earphone 100 is close to the concha 221, thereby improving the sound quality of the earphone. It should be noted that the sound quality in this embodiment includes both the volume of the earphone and the clarity of the sound.

[0060] The ear clip 120 bypasses the area of ​​the helix 210 and the concha cavity 221 opposite to it, so that the end of the ear clip 120 away from the headphone head 110 is located on the back side of the ear 200. Thus, the headphone 100 in this embodiment is an ear clip type.

[0061] Please refer to the attached document. Figure 4 The earphone head 110 includes a first housing 111, the inner cavity of which is used to house the components of the earphone 100. For example, the inner cavity of the first housing 111 can be used to house a sound-generating device, a microphone or other components.

[0062] The earphone head 110 also includes a camera hole 112 and a camera unit 113. The camera hole 112 is disposed on the first housing 111 and communicates with the inner cavity of the first housing 111, so that the camera hole 112 is a through hole extending along the thickness direction of the first housing 111. The camera hole 112 can be circular, square, elliptical or other arbitrary shapes, and this embodiment does not limit it.

[0063] It should be noted that a waterproof and light-transmitting membrane can also be provided on the camera hole 112, so that while the camera unit 113 captures clear and bright images and videos, it can also effectively prevent moisture from entering the inside of the earphone head 110, thereby protecting the camera unit 113 and other internal electronic components from moisture damage and improving the service life of the earphone 100.

[0064] A camera unit 113 is disposed within the first housing 111 and configured to acquire images and / or videos of the external environment through a camera aperture 112. This configuration allows the headphones to perform both music listening and call functions while also possessing a shooting function, enhancing the headphones' versatility and thus their usability. For example, when a user wears the headphones for outdoor activities, the headphones 100 can use the camera unit 113 to record and photograph the surrounding environment. The headphones 100 can also interact with external devices based on the captured images of the surrounding environment to assess the environment and improve user safety. As another example, when a user wears the headphones during a remote conference, the headphones 100 can capture the user's vocalizations and gestures, providing accurate command input for AI.

[0065] The earphones provided in this application embodiment, when worn, can be used to acquire images and / or videos from the side and / or front of the user. In some embodiments, when worn and along the direction of the human sagittal axis, the first housing 111 includes a first wall 1111 and a second wall 1112 disposed opposite to each other, the second wall 1112 facing the concha cavity 221; or, in the direction of the human sagittal axis, the first wall 1111 is a wall facing the front of the user, and the second wall 1112 is a wall facing the rear of the user.

[0066] A camera hole 112 is disposed on and penetrates the first wall surface 1111; a camera unit 113 is disposed on the side of the first wall surface 1111 facing the inner cavity of the first housing 111, and is located at the camera hole 112. Thus, when the headphones are worn, they can directly capture the area in front of the user's face through the camera hole 112, thereby obtaining image and / or video information in the user's line of sight.

[0067] In other embodiments, the camera unit 113 may also be disposed on the side of the second wall 1112 facing the inner cavity of the first housing 111, and directly opposite the camera hole 112. In this way, the placement of the camera unit 113 can be flexibly adjusted according to the layout of the various components within the first housing 111, thereby improving the design flexibility of the earphone 100.

[0068] Regarding the selection of the location of the camera hole 112 on the first wall surface 1111, it can be placed as far away as possible from the tragus of the ear 200 to avoid the facial area near the tragus obstructing the camera unit 113. For example, the camera hole 112 is located near the connection area between the first wall surface 1111 and the ear clip 120. It should be noted that the connection area in this embodiment can be understood as the interface where the first wall surface 1111 connects and contacts the ear clip 120, and the camera hole 112's proximity to this connection area can be used as a boundary, with a preset distance between the camera hole 112 and this boundary. This arrangement allows the camera unit 113 to directly face the user's front, facilitating the capture of user gestures or environmental information, while avoiding the user's ear obstructing the camera, reducing blind spots caused by the face, and maximizing the shooting range and image quality of the camera unit 113. On the other hand, it can also help optimize the spatial layout within the first housing 111, allowing the camera unit 113 and other components to be more compactly integrated within the first housing 111.

[0069] In some embodiments, the imaging unit 113 has an optical axis. The optical axis can be understood as the center of the lens of the imaging unit 113 and an imaginary straight line perpendicular to the imaging plane of the image sensor. Alternatively, the optical axis is the axis of symmetry of the imaging unit 113.

[0070] When the headphones are worn, the angle between the optical axis and the sagittal plane of the human body is -20° to 5°, and / or the angle between the optical axis and the horizontal plane of the human body is -10° to -35°. For example, the angle between the optical axis and the sagittal plane of the human body is -20°, -15°, -10°, -5°, 0°, and 5°. The angle between the optical axis and the horizontal plane of the human body is -10°, -15°, -20°, -25°, -30°, and -35°.

[0071] This embodiment optimizes the shooting angle of the camera unit 113 by setting the angle between the optical axis and the sagittal plane of the human body and / or the angle between the optical axis and the horizontal plane of the human body, making it more ergonomically designed. This allows the camera unit 113 to more naturally capture the surrounding environment in the user's line of sight when wearing the headphones 100, minimizing blind spots and ensuring a wider field of view.

[0072] In some embodiments, the earphone 100 further includes a voice processing unit 130 disposed within the first housing 111.

[0073] When worn, the area of ​​the first housing 111 opposite the voice processing unit 130 contacts the inner wall of the concha 221. Based on the fact that sound can be transmitted through the skull as a medium, the voice processing unit 130 receives bone-conducted voice signals. When the user is in a noisy environment, given that bone-conducted voice signals are minimally affected by ambient noise, the voice processing unit 130 can pick up the voice signal more clearly and accurately. This allows the user to communicate with others in a quieter voice, improving the privacy of the headset and enabling private voice communication even in public places or noisy environments.

[0074] In addition, the voice processing unit 130 can also cooperate with the microphone of the headset 100. The microphone of the headset 100 receives voice signals transmitted through the air, and the voice processing unit 130 receives voice signals transmitted through bone conduction. By comparing the two voice signals, if the two voice signals have a high degree of consistency in time and frequency, it can be determined that the user is speaking; otherwise, it can be determined that the user is not speaking. In this case, the microphone can be automatically turned off when the user is not speaking, thereby enhancing user privacy protection, which is especially important in certain sensitive scenarios.

[0075] It's important to understand that the voice processing unit 130 receives voice signals transmitted via bone conduction; therefore, the closer the voice processing unit 130 is to the face, the better. Please refer to the appendix. Figure 4 For example, the earphone head 110 includes a protrusion 114 protruding toward the concha cavity 221, and the voice processing unit 130 is disposed in a cavity formed by the protrusion 114 and the earphone head 110 for housing. For example, a portion of the first housing 111 protrudes toward the concha cavity 221 to form the protrusion 114, that is, a portion of the second wall surface 1112 protrudes toward the concha cavity 221 to form the protrusion 114. With this configuration, the first housing 111 and the protrusion 114 can be a single piece, which simplifies the manufacturing process and reduces manufacturing costs and assembly complexity. In addition, the design of the protrusion 114 can be finely adjusted according to the user's ear contour, making the earphone more fit individual characteristics and enhancing the aesthetics and personalization of wearing it. At the same time, this design also provides more design space for the earphone to meet the aesthetic needs of different users.

[0076] When worn, the protrusion 114 is located within the concha 221 and contacts the inner wall of the concha 221. This allows for more effective reception of speech signals transmitted via bone conduction, reducing signal attenuation and interference during transmission, and improving the clarity and sensitivity of the speech signal.

[0077] In some embodiments, please refer to the appendix. Figure 6 The earphone 100 also includes a control unit 180, which is connected to the voice processing unit 130 and the camera unit 113 respectively. The control unit 180 is used to generate instructions to control the camera unit 113 based on the voice signal from the voice processing unit 130.

[0078] The camera unit 113 can take photos or videos of the user's surroundings when needed. However, if the camera unit 113 remains active when this function is not required, it will increase the power consumption of the headset 100 and reduce its standby time. Therefore, in this embodiment, the voice processing unit 130 and the camera unit 113 can be linked through the control unit 180. By controlling the camera unit 113 to start and stop via voice, the continuous operation of the camera unit 113 when not needed is avoided, thereby significantly reducing the overall power consumption of the headset 100. This intelligent energy-saving mechanism can extend the standby time and continuous use time of the headset, improving the user experience.

[0079] In other embodiments, the images and / or videos acquired by the camera unit 113 need to be transmitted to an external electronic device for processing, such as a mobile phone or computer. Therefore, the headset provided in this embodiment also includes a communication module. The camera unit 113 connects to the external electronic device through the communication module, eliminating the need for the cumbersome steps of connecting traditional headsets to smartphones and then transmitting data via Bluetooth, thus improving user convenience.

[0080] In one possible implementation, the ear clip 120 includes a first ear clip 121 and a second ear clip 122, the first ear clip 121 spanning the helix and connecting the earphone head 110 and the second ear clip 122; the second ear clip 122 extends along the back contour of the helix 210 and contacts the back of the ear.

[0081] 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. The U-shaped earphone 100 has better stability and can more effectively fit the contour of the user's ear. In particular, when the second ear clip 122 extends along the contour of the back of the ear helix and contacts the back of the ear, it greatly increases the stability of the earphone and reduces the risk of the earphone accidentally falling off during exercise or activity.

[0082] The design of the first ear clip 121 also increases the area of ​​the earphone spanning the helix, thereby allowing for the targeted placement of some components of the earphone 100 at the first ear clip 121, improving the compactness of the earphone 100 layout. For example, the first ear clip 121 includes a second housing, within which a circuit board 140 is disposed; the circuit board 140 is respectively connected to the camera unit 113 and the voice processing unit 130.

[0083] The camera unit 113 and the voice processing unit 130 are disposed within the first housing 111, and the circuit board 140 is disposed within the second housing adjacent to the first housing 111. This shortens the distance between the camera unit 113 and the voice processing unit 130 and the circuit board 140, which helps to shorten the wiring layout between the circuit board 140 and the camera unit 113, as well as between the circuit board 140 and the voice processing unit 130. This shortens the signal transmission path, reduces signal attenuation and interference, thereby optimizing data transmission efficiency and signal quality, and improving the overall performance of the headphones.

[0084] In other embodiments, the second ear clip 122 can be made of a rigid material or an elastic material. For example, the second ear clip 122 is a support made of an elastic material. The elastic material may include materials such as silicone, thermoplastic polyurethane (TPU), or memory titanium wire, allowing the user to adaptively adjust according to different wearing habits, ensuring the earphones fit securely against the user's ear and reducing the risk of the earphones falling out.

[0085] In addition, the second ear clip 122, made of silicone and thermoplastic polyurethane (TPU), provides users with cushioning and a comfortable wearing experience, effectively dispersing the pressure of the headphones on the ears and reducing discomfort caused by prolonged wear.

[0086] In one possible implementation, the earphone 100 further includes a touch unit 170, which is disposed on the circuit board 140 and is attached to the wall of the second housing opposite to the ear 200. The addition of the touch unit 170 allows the user to control the earphone 100 through simple touch operations, such as adjusting volume, switching audio, and starting / stopping video recording. Furthermore, the fact that the touch unit 170 is attached to the wall of the second housing opposite to the ear 200 improves the touch sensitivity of the touch unit 170.

[0087] In one possible implementation, the second ear clip 122 includes a third housing, within which a battery 150 is disposed. The battery 150 is electrically connected to the circuit board 140, the camera unit 113, and the voice processing unit 130, respectively. Utilizing the battery 150 to provide power to the circuit board 140, the camera unit 113, and the voice processing unit 130 helps ensure the stable operation and optimal performance of each functional module of the headset (such as the camera unit and the voice processing unit).

[0088] It should be noted that the cross-sectional areas of the first ear clip 121 and the second ear clip 122 can be equal everywhere, or other options are also possible. As an example, the cross-sectional area of ​​the second ear clip 122 is larger than that of the first ear clip 121, allowing the second ear clip 122 to 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 headphones. This helps reduce the risk of the headphones accidentally falling off during exercise or activity.

[0089] Furthermore, the second ear clip 122 helps to further optimize the weight distribution of the headphones 100. By concentrating some of the weight on the back of the ear, the pressure of the headphones on the helix and ear canal can be reduced, making the wearing experience more comfortable and natural, especially suitable for users who need to wear headphones for extended periods of time.

[0090] In one possible implementation, the earphone 100 further includes a sound-emitting part 160, which is disposed on the side of the earphone head 110 facing the concha cavity 221; in the coronal axis direction of the human body, the sound-emitting part 160 is stacked with the second wall surface 1112 of the earphone head 110. This effectively improves space utilization, allowing the overall size of the earphone head 110 and the sound-emitting part 160 to be smaller, thus making the entire earphone smaller, more portable, and lighter, easier for people with smaller ears to wear, and increasing the applicability of the earphone.

[0091] Furthermore, the overlapping arrangement of the sound-emitting part 160 and the second wall surface 1112 of the earphone head 110 in the direction of the human coronal axis can also help the sound-emitting part 160 extend into the concha cavity 221, thereby making the sound-emitting part 160 closer to the ear canal opening 280, and improving the sound quality and volume performance of the earphone 100.

[0092] In some embodiments, the sound-emitting part 160 is disposed within the first housing 111. In this case, a portion of the second wall 1112 of the first housing 111 protrudes toward the concha cavity 221, such that the second wall 1112 forms a receiving cavity that communicates with the inner cavity of the first housing 111. The sound-emitting part 160 is disposed within the receiving cavity. Since the receiving cavity is closer to the ear canal opening, it helps to promote natural audio transmission, reduces attenuation and distortion, and makes the audio more realistic and natural.

[0093] In this embodiment, a sound outlet is provided on the wall surface of the first housing 111 opposite to the sound-emitting part 160. The sound outlet communicates with the inner cavity of the first housing 111, and the audio signal generated by the sound-emitting part 160 can be transmitted to the ear canal opening through the sound outlet.

[0094] It should be noted that when the first housing 111 includes a receiving chamber, the sound outlet can be located on the bottom wall and / or side wall of the receiving chamber. By cleverly placing the sound outlet at an appropriate position in the first housing (such as the bottom wall or side wall of the receiving chamber), this embodiment can ensure that sound enters the ear canal at the optimal angle and manner, reducing the discomfort of sound directly impacting the eardrum.

[0095] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.
