Description

Technical Field

[0001] This utility model relates to the field of smart wearable device technology, and in particular to an earphone. Background Technology

[0002] With the widespread adoption of smart wearable devices, wireless Bluetooth headphones with cameras have garnered significant attention due to their ability to meet users' audio and video recording and communication needs in various scenarios. Sports enthusiasts expect to easily record scenery and their own physical activity while cycling or hiking; social media creators want to capture memorable moments for content creation; and business professionals need to record important information during meetings. However, current products have significant shortcomings. During dynamic use, such as walking, running, or other activities, the camera's image is easily blurred due to shaking, severely impacting image quality and failing to meet the requirement for clear recording. This issue greatly limits the practical application of wireless Bluetooth headphones with cameras in many dynamic scenarios. Furthermore, the camera components in existing products are often fixed and non-adjustable, making it difficult to flexibly adjust the shooting angle according to the usage scenario; the connection method between the control components and the camera suffers from unstable signal transmission and complex structure; and the drive components lack precise control when rotating the camera, easily leading to mechanical wear and noise. These technical deficiencies collectively restrict the functional expansion and user experience of headphones with cameras, urgently requiring solutions through innovative structural design. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0010] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0011] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0012] In existing technologies, wireless Bluetooth headsets with cameras suffer from blurry images during dynamic use. When users are in motion, the camera lacks an effective stabilization mechanism and cannot eliminate the effects of external vibrations, leading to a decline in image quality. Traditional solutions often employ software algorithms for compensation, but due to hardware limitations, they cannot fundamentally solve the image shift problem caused by physical displacement.

[0013] To address these issues, the inventors discovered that dynamic jitter not only originates from user movement but is also related to the camera module's lack of active adjustment capabilities. Analysis revealed that the rigid connection between the camera and the earphone body limits the possibility of angle adjustment. Based on this, the design approach shifted to constructing a closed-loop control system combining mechanical transmission and electronic feedback. This system utilizes a movable structure to counteract external vibrations and achieves dynamic balance through real-time monitoring and drive adjustments.

[0014] This utility model proposes an earphone.

[0015] Please see Figures 1 to 3 The earphone includes a main body 1, a camera assembly 2, a control assembly 3, and a driver 4. The main body 1 has a receiving cavity 11. The camera assembly 2 includes a housing 21 and a camera 22. The housing 21 is mounted on the main body 1, and an opening 214 is provided on one side of the housing 21. The camera 22 is mounted inside the housing 21 and is positioned corresponding to the opening 214. The control assembly 3 includes a sensing part 33, which is located inside the housing 21. The driving component 4 includes a cylinder body 41 and a rotating shaft 42 that is connected to the cylinder body 41 in a transmission manner. The cylinder body 41 is disposed in the receiving cavity 11. The sensing part 33 is connected to the cylinder body 41 in a signal manner. The rotating shaft 42 passes through the main body 1 and is connected to the housing 21. The driving component 4 is used to drive the housing 21 to rotate relative to the main body 1.

[0016] The main body 1 refers to the supporting structure that carries the internal components, and its cavity 11 provides installation space for the internal components. The housing 21 in the camera assembly 2 is the encapsulation component that protects the camera 22. Specifically, it can adopt a split design, combining the bottom cover 211 and the front cover 212, with the lens 5 installed at the opening 214 to protect the lens. The cylinder body 41 is the device that provides rotational power, which can be implemented using a micro stepper motor, transmitting torque through a gear set meshing with the rotating shaft 42. The rotating shaft 42 is the component that drives the cylinder body 41. One end of the rotating shaft 42 passes through the main body 1 and is driven by the cylinder body 41, while the other end of the rotating shaft 42 is connected to the housing 21. Specifically, it can be a hollow metal shaft with a flexible circuit board 32 running through it to maintain unobstructed wiring.

[0017] Specifically, when the headphones are in working condition, that is, when the camera 22 on the headphones is recording, the sensor 33 set in the housing 21 can sense changes in position and angle in real time. When the sensor 33 senses a change in position and angle, the cylinder body 41 connected to the sensor 33 drives the rotating shaft 42 to rotate, thereby causing the housing 21 to rotate relative to the main body 1 around the axis of the rotating shaft 42, thereby adjusting the position and angle of the camera 22, keeping the camera 22 stable, and effectively reducing the displacement amplitude of the camera 22 during movement.

[0018] In another embodiment, the earphone includes a main body 1, a camera assembly 2, a control assembly 3, and a drive unit 4. The main body 1 has a receiving cavity 11. The camera assembly 2 includes a housing 21 and a camera 22. The housing 21 is mounted on the main body 1, and an opening 214 is provided on one side of the housing 21. The camera 22 is mounted inside the housing 21 and is positioned corresponding to the opening 214. The control assembly 3 includes a main circuit board 31, a flexible circuit board 32, and a sensing unit 33. The main circuit board 31 is mounted inside the receiving cavity 11. One end of the flexible circuit board 32 extends into the receiving cavity 11 and is signal-connected to the main circuit board 31. The other end of the flexible circuit board 32 extends into the housing 21. The camera 22 is mounted on the flexible circuit board 32. The sensing unit 33 is located inside the housing 21 and mounted on the flexible circuit board 32. The drive unit 4 includes a cylinder body 41 and a rotating shaft 42 that is pulsatorically connected to the cylinder body 41. The cylinder body 41 is disposed inside the receiving cavity 11 and is signal-connected to the main circuit board 31. The rotating shaft 42 passes through the main body 1 and is connected to the housing 21. The drive unit 4 is used to drive the housing 21 to rotate relative to the main body 1.

[0019] Among them, the flexible circuit board 32 refers to a bendable conductive line carrier, which can be an FPC flexible connection board, used to transmit electrical signals and carry the sensing part 33.

[0020] Specifically, when the headphones are in operation, i.e., when the camera 22 on the headphones is recording, the sensor 33 mounted on the flexible circuit board 32 continuously monitors the motion parameters of the camera 22. The main circuit board 31 calculates the compensation angle based on the sensor data and sends a control command to the cylinder body 41. The cylinder body 41 drives the rotating shaft 42 to rotate, causing the housing 21 to rotate relative to the main body 1 around the axis of the rotating shaft 42. This rotation of the housing 21 relative to the main body 1 adjusts the position and angle of the camera 22, keeping it stable and effectively reducing the displacement of the camera 22 during movement.

[0021] Compared to existing technologies, traditional headphone camera modules (22 modules) are fixedly mounted and cannot cope with multi-directional jitter in complex motion scenarios. This solution introduces an active drive mechanism and a closed-loop feedback system, enabling the camera module (22 modules) to adjust its posture in real time, thus counteracting displacement interference at the mechanical structure level. The combined design of the rotating shaft (42) and the flexible circuit board (32) solves the wiring connection problem between moving parts, ensuring reliable signal transmission.

[0022] Through the above technical solutions, this application achieves active stabilization control of the camera 22 in dynamic environments. The mechanical transmission structure, combined with the electronic feedback system, forms a physical image stabilization mechanism, effectively reducing the displacement of the camera 22 during movement. The flexible circuit board 32 establishes a stable electrical connection between moving parts, ensuring real-time transmission of sensor data and drive commands. The adjustable angle design of the housing 21 allows the camera 22 to switch its working state according to different usage scenarios, balancing storage protection with shooting needs.

[0023] In one embodiment, please refer to Figures 3 to 5 The sensing unit 33 includes a gyroscope 331 and a first sensor 332 mounted on the flexible circuit board 32. The gyroscope 331 is used to detect the angular velocity change of the camera 22, and the first sensor 332 is used to detect the linear acceleration change of the camera 22. The angular velocity change and linear acceleration change of the camera 22 are fed back to the main circuit board 31 through the flexible circuit board 32.

[0024] Among them, the gyroscope 331 is a sensor used to measure changes in angular velocity, specifically a microelectromechanical system (MEMS) gyroscope 331, which captures attitude changes by detecting the rotational angular velocity of the camera 22 around different axes. The first sensor 332 is a sensor used to detect linear acceleration, specifically a triaxial accelerometer, which identifies the motion trajectory by measuring the linear displacement of the camera 22 in three-dimensional space. The flexible circuit board 32 is a bendable circuit board that utilizes its deformation capability to adapt to the bending requirements of the circuitry when the housing 21 rotates.

[0025] Specifically, the gyroscope 331 and the first sensor 332 form a dual-modal detection structure on the flexible circuit board 32. The gyroscope 331 collects the rotational angular velocity data of the camera 22 around the X, Y, and Z axes in real time, while the first sensor 332 simultaneously acquires the acceleration data of the camera 22 in the three orthogonal directions. The two types of data are transmitted to the main circuit board 31 through the internal circuitry of the flexible circuit board 32. The main circuit board 31 performs fusion calculation on the rotational angular velocity and linear acceleration to analyze the three-dimensional motion trajectory of the camera 22. When the camera 22 shakes due to user movement, the angular velocity change detected by the gyroscope 331 and the acceleration change detected by the first sensor 332 together constitute state information. The main circuit board 31 generates corresponding drive compensation commands based on this information, and adjusts the angle of the housing 21 through the drive component 4 to compensate for the displacement deviation caused by the shaking.

[0026] Compared to existing technologies, traditional solutions rely on a single sensor to detect single-dimensional motion, such as using only an accelerometer to detect linear displacement, which cannot accurately distinguish between rotational jitter and linear jitter. This solution achieves full-dimensional detection of rotational and linear motion through data complementarity between the gyroscope 331 and the accelerometer, eliminating the blind spots of single-sensor detection. In existing technologies, sensors are usually installed independently and connected to the circuit board via cables, resulting in complex internal wiring of the earphone 100 and making the wiring prone to breakage due to the rotation of the housing 21. This solution integrates the sensor directly into the flexible circuit board 32, utilizing its bendability to avoid wiring tangling and reduce the number of connection interfaces.

[0027] Through the above technical solution, this application can accurately identify the complex motion state of the camera 22 during dynamic use, improve motion resolution accuracy through dual-sensor data fusion, provide more comprehensive input parameters for image stabilization control, effectively reduce the superimposed impact of rotational and linear shaking on the captured image, and improve image clarity in dynamic scenes. The integrated design of the sensor and flexible circuit board 32 achieves stable signal transmission within a limited space, avoids circuit damage caused by the rotation of the housing 21, and improves structural reliability.

[0028] Please refer to Figure 6 and Figure 7In one embodiment, when the housing 21 moves relative to the main body 1 to a first preset position, the main circuit board 31 controls the camera 22 to turn on; when the housing 21 moves relative to the main body 1 to a second preset position, the main circuit board 31 controls the camera 22 to turn off.

[0029] In this embodiment, Figure 6 The housing 21 is in the first preset position, at which time the main circuit board 31 controls the camera 22 to turn on. Figure 7 The middle housing 21 is in the second preset position, at which time the main circuit board controls the camera 22 to turn off.

[0030] The housing 21 is capable of rotating relative to the main body 1 under the drive of the cylinder body 41. When the housing 21 rotates relative to the main body 1 to a first preset position under the drive of the rod body, the first preset position can be the position of the housing 21 when the angle between the housing 21 and the main body 1 is 90 degrees. In other embodiments, the first preset position can be other than those specified in this specification. When the housing 21 rotates relative to the main body 1 under the drive of the cylinder body 41 and rotates to a second preset position, the second preset position can be the position of the housing 21 when the main body 1 and the housing 21 are flush. In other embodiments, the second preset position can be other than those specified in this specification.

[0031] Based on the above embodiments, a second sensor 311 is installed on the main circuit board 31, and a trigger 321 is also installed at one end of the flexible circuit board 32 that extends into the housing 21. The second sensor 311 is used to detect the position information of the trigger 321. When the trigger 321 is in the first preset position, the main circuit board 31 controls the camera 22 to turn on; when the trigger 321 is in the second preset position, the main circuit board 31 controls the camera 22 to turn off.

[0032] The second sensor 311 is an electronic component used to detect changes in the position of the trigger 321. Specifically, it can be implemented using a Hall effect IC, which can sense the relative position of the trigger 321 through changes in the magnetic field. The trigger 321 is a component that works with the second sensor 311 to generate a position signal. Specifically, it can be implemented using a Hall effect magnet. The Hall effect magnet and the Hall effect IC work together to form a non-contact position detection mechanism.

[0033] Specifically, when the housing 21 rotates relative to the main body 1, the flexible circuit board 32 installed inside the housing 21 and the trigger 321 installed on the flexible circuit board 32 move synchronously. The second sensor 311 determines its position by detecting the change in the magnetic field of the trigger 321. When the housing 21 rotates to the first preset position, the relative position of the trigger 321 and the second sensor 311 reaches the first threshold, and the main circuit board 31 controls the camera 22 to start according to the signal; when the housing 21 rotates to the second preset position, the relative position of the trigger 321 and the second sensor 311 reaches the second threshold, and the main circuit board 31 controls the camera 22 to turn off.

[0034] Compared to existing technologies, current camera switch control relies heavily on mechanical contacts or a single sensor. Mechanical contacts are prone to poor contact due to frequent rotation, while single sensors pose a risk of misjudgment. This solution achieves position detection without physical contact through the combination of a Hall IC and a Hall magnet. Furthermore, a dual-threshold design distinguishes different states, significantly improving detection accuracy and system reliability.

[0035] Through the above technical solution, this application realizes the automatic correlation control between the rotation position and functional status of the camera 22. The user only needs to rotate the housing 21 to trigger the camera 22 to turn on or off, avoiding the cumbersomeness of manual operation. At the same time, it solves the problems of short life of mechanical switches and false triggering of single sensors, and improves the ease of operation and system stability in dynamic usage scenarios.

[0036] In one embodiment, the main body 1 has a through hole 12 on the side facing the housing 21, which communicates with the receiving cavity 11. The rotating shaft 42 passes through the through hole 12 to connect the main body 1 and the housing 21. The rotating shaft 42 is hollow. One end of the flexible circuit board 32 passes through the rotating shaft 42 and extends into the receiving cavity 11. A first gear 421 is provided outside the rotating shaft 42. The output shaft of the cylinder body 41 is connected to a second gear 411 that meshes with the first gear 421.

[0037] The through hole 12 refers to the through hole 12 formed at the connection between the main body 1 and the shell 21. It can be achieved through machining or injection molding, and is used to accommodate the rotating shaft 42 and limit its movement trajectory. The rotating shaft 42 is a hollow structure connecting the main body 1 and the shell 21, allowing the flexible circuit board 32 to pass through it for circuit protection during rotation. The first gear 421 is a transmission component fixed to the outer periphery of the rotating shaft 42, which can be manufactured using powder metallurgy. Its tooth profile parameters are matched and mesh with the second gear 411. The second gear 411 is a power transmission component installed at the output end of the drive component 4, transmitting driving torque to the first gear 421 through tooth surface meshing.

[0038] Specifically, the fit between the through hole 12 and the rotating shaft 42 forms an axial positioning constraint, limiting the radial displacement of the housing 21 during rotation. The internal space of the hollow rotating shaft 42 is completely penetrated by the flexible circuit board 32, so that the signal transmission line between the camera 22 and the control component 3 is wrapped inside the rigid structure, preventing the wires from getting tangled or stretched during rotation. The rotational power output by the drive component 4 is transmitted to the rotating shaft 42 through the meshing of the second gear 411 and the first gear 421. The reduction ratio design of the gear pair can improve the torque output accuracy and ensure the stability of the rotational angular velocity of the housing 21. The gap between the rotating shaft 42 and the through hole 12 is controlled within the range of 0.05-0.1 mm, which ensures smooth rotation and prevents radial wobble.

[0039] Through the above technical solution, this application solves the problem of camera 22 shaking due to mechanical instability during dynamic use. The precise fit between the rotating shaft 42 and the through hole 12 suppresses radial displacement, the gear meshing transmission improves rotation control accuracy, and the circuit protection design of the hollow rotating shaft 42 avoids interference from wire movement. These technical features work together to ensure that the camera 22 can maintain a stable shooting angle even in motion, significantly improving image clarity.

[0040] In one embodiment, the earphone 100 further includes a sealing ring, which is fitted onto the outer wall of the pivot 42.

[0041] The sealing ring is a ring-shaped elastic element, which can be made of rubber or silicone. It fills the gap between the rotating shaft 42 and the main body 1 through elastic deformation. The sealing ring maintains continuous contact pressure during the rotation of the rotating shaft 42, forming a dynamic sealing interface. The outer wall of the rotating shaft 42 refers to the outer surface area of ​​the cylindrical rotating shaft 42 in the drive component 4 that connects the main body 1 and the housing 21. The inner diameter of the sealing ring and the outer diameter of the rotating shaft 42 form an interference fit, ensuring that the sealing ring tightly adheres to the surface of the rotating shaft 42.

[0042] Specifically, when the rotating shaft 42 drives the housing 21 to rotate relative to the main body 1, the sealing ring continuously covers the annular gap at the connection between the rotating shaft 42 and the main body 1 through elastic deformation. During dynamic rotation, the inner edge of the sealing ring maintains sliding contact with the outer wall of the rotating shaft 42, while the outer edge forms a fixed seal with the mounting hole of the main body 1. This double-sealing structure continuously prevents dust particles or liquid water droplets with a diameter greater than 50 micrometers from entering the receiving cavity 11 through the gap within the rotation angle range of the rotating shaft 42. The continuous annular coverage of the sealing ring eliminates the leakage path present in traditional segmented seals, preventing external impurities from entering the gear meshing area of ​​the drive component 4 and the mounting space of the main circuit board 31 along the axial or radial direction.

[0043] Through the above technical solution, this application effectively prevents external contaminants from entering the earphone 100 through the connection of the rotating shaft 42, avoids the gear of the drive component 4 from being stuck due to foreign objects causing deviation in the rotation angle, and ensures that the camera 22 can still achieve optical image stabilization compensation through precise rotation control in motion, thus maintaining the stability of image acquisition.

[0044] In one embodiment, the housing 21 includes a bottom cover 211 and a front cover 212 connected to each other. The bottom cover 211 is disposed close to the main body 1, and the front cover 212 has an opening 214. The bottom cover 211 is disposed close to the main body 1 and is connected to the main body 1 by a pivot 42. The front cover 212 is connected to the bottom cover 211. Specifically, the front cover 212 and the bottom cover 211 can be connected in a detachable manner, which facilitates the installation and maintenance of the camera 22 and the sensing part 33 on the flexible circuit board 32 mounted on the housing 21.

[0045] In one embodiment, the earphone 100 further includes a lens 5, which is mounted at the opening 214. The lens 5 is a transparent optical component covering the opening 214, specifically made of high-transmittance optical glass or optical-grade plastic material, such as a material with a transmittance of not less than 99%, used to allow light to pass through while protecting the camera 22. The opening 214 is a hole in front of the camera 22 for receiving external light; the lens 5 covers this hole through a sealed mounting method, forming a physical barrier to prevent external dust or liquids from directly contacting the camera 22.

[0046] Specifically, the lens 5 is fixed to the edge of the housing 21, forming a sealed structure through snap-fit ​​or adhesive bonding. When the camera 22 is working, external light passes through the lens 5 into the housing 21 and is received by the camera 22. The high light transmittance of the lens 5 reduces light refraction loss, ensuring sufficient light intake even in low-light environments. The surface of the lens 5 can be coated to suppress reflective interference, while its scratch resistance extends its service life. The sealing structure between the lens 5 and the housing 21 also prevents sweat or rainwater from seeping into the housing 21 during exercise.

[0047] Through the above technical solution, this application solves the problem of image quality degradation caused by environmental interference in camera 22. The lens 5 isolates external pollutants and improves light utilization, enabling camera 22 to output clear images in dynamic usage scenarios and low-light environments, while avoiding equipment damage caused by external environmental factors.

[0048] In one embodiment, the earphone 100 further includes a heat sink 6, which is disposed within the receiving cavity 11 and attached to the main circuit board.

[0049] The heat sink 6 refers to a metal heat-conducting component that forms a heat conduction path with the main circuit board 31. It can be made of aluminum or copper thin plates, and its surface can be provided with fin structures to increase the heat dissipation area. This component transfers the heat generated by the main circuit board 31 to the earphone 100 shell through physical contact, and utilizes the high thermal conductivity of the metal material to achieve rapid heat diffusion.

[0050] Specifically, the heat sink 6 is fixed to the inner wall of the receiving cavity 11 and tightly fitted to the main circuit board 31. When the main circuit board 31 is running, the heat it generates is transferred to the heat sink 6 through direct contact. The heat sink 6 then conducts the heat to the metal part of the earphone 100 shell, and the heat is dissipated through natural convection between the shell surface and the air. This design allows heat to be quickly dissipated from areas where electronic components are concentrated, preventing localized overheating that could cause malfunctions in the circuit board components. The thickness of the heat sink 6 can be controlled between 0.5 mm and 1 mm, ensuring heat dissipation efficiency without increasing the overall size of the earphone 100.

[0051] Through the above technical solution, this application effectively reduces the operating temperature of the main circuit board 31, prevents the camera 22's image stabilization function from experiencing control signal delays due to excessive temperature, and avoids performance degradation of electronic components due to overheating. The contact-type heat conduction design between the heat sink 6 and the circuit board ensures that the earphone 100 can maintain stable image processing capabilities under continuous use scenarios, extending the service life of the internal electronic components.

[0052] In one embodiment, a light groove 213 is provided on the side of the housing 21 away from the main body 1, and a light-emitting diode 2131 is provided in the light groove 213. The light-emitting diode 2131 is electrically connected to the flexible circuit board 32.

[0053] The lamp groove 213 refers to a recessed structure located on the side of the housing 21 away from the main body 1. Specifically, it can be formed into a groove of a specific shape on the surface of the housing 21 using injection molding, used to fix the light-emitting diode 2131 and restrict its installation position. The light-emitting diode 2131 can specifically adopt a surface-mount LED package structure, fixed within the lamp groove 213 by soldering or conductive adhesive, achieving low-power light emission. The electrical connection of the flexible circuit board 32 refers to the formation of an electrical path between the light-emitting diode 2131 and the main circuit board 31 through conductive lines on the flexible circuit board 32. Specifically, it can be achieved using gold wire bonding or conductive silver paste, enabling the main circuit board 31 to control the switching state of the light-emitting diode 2131.

[0054] Specifically, when the camera 22 is in operation, the main circuit board 31 sends an electrical signal to the light-emitting diode 2131 via the flexible circuit board 32, triggering the light-emitting diode 2131 to emit light and form a visible light prompt. When the camera 22 is turned off, the main circuit board 31 cuts off the electrical signal transmission, and the light-emitting diode 2131 turns off. This process achieves signal transmission and power supply control through the flexible circuit board 32, ensuring that the state of the light-emitting diode 2131 is synchronized with the operating state of the camera 22.

[0055] Through the above technical solution, this application can display the working status of the camera 22 in real time, helping users to quickly identify the device's operating mode.

[0056] In one embodiment, the earphone 100 further includes an ear hook 7, which is connected to the outside of the main body 1 and forms a contoured part with the main body 1 for hanging on the ear.

[0057] The ear hook 7 refers to the extension structure connected to the outside of the main body 1 of the earphone 100. It can be made of polycarbonate material with elastic deformation capability and is integrally connected to the main body 1 through injection molding. The conforming part refers to the arc-shaped clamping structure formed by the ear hook 7 and the main body 1. It can be made of an arc design with a curvature radius adapted to the root of the human ear helix, and its inner surface can be provided with an anti-slip silicone layer.

[0058] Specifically, the ear hook 7 and the main body 1 form a contoured portion that wraps around the root of the helix when worn. This contoured portion can be C-shaped, utilizing the bony structure of the auricle to create three-point support. The elastic material of the ear hook 7 deforms under stress, and the reaction force presses the main body 1 of the earphone 100 against the surface of the concha. The arc-shaped structure of the contoured portion ensures that pressure is evenly distributed across the helix crus, the lower antihelix crus, and the upper part of the earlobe, preventing excessive local pressure. When the body moves and generates inertial force, the elastic deformation of the ear hook 7 absorbs horizontal displacement, while the rigid support structure of the contoured portion suppresses vertical swaying, thus forming a multi-dimensional displacement constraint mechanism.

[0059] Compared to existing technologies, traditional in-ear headphones rely on ear canal friction for fixation, making them prone to loosening during vigorous exercise. The new design, combining ear hooks with a contoured section, uses an anatomically adapted support structure to shift the fixation point from the ear canal to the bony region of the auricle. This avoids pressure on the ear canal and leverages the rigidity of the auricle to enhance stability. Existing in-ear structures using external auditory canal support are highly susceptible to individual differences in ear canal fit, while this solution significantly improves adaptability to different ear shapes through a multi-point support structure on the outside of the auricle.

[0060] Through the above technical solution, this application can reduce the relative displacement between the main body 1 of the earphone 100 and the human ear in dynamic usage scenarios such as cycling and running, reduce the inter-frame jitter amplitude of the image captured by the camera 22, and maintain a pressure-free feeling even after three hours of continuous wear. The elastic deformation characteristics of the ear hook 7 can effectively dampen low-frequency vibrations, while the rigid support structure of the C-shaped part suppresses high-frequency micro-shaking, thereby achieving isolation of multi-frequency motion interference.

Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
