Description

Technical Field

[0001] This invention belongs to the field of smart wearable device technology, specifically relating to a wearable gesture recognition sports Bluetooth headset. Background Technology

[0002] Sports Bluetooth headsets are a type of headset specifically designed for sports and fitness activities. Compared to traditional wired headsets and ordinary single-ear Bluetooth headsets for business calls, they offer significant improvements in waterproofing, anti-drop-off performance, and sound quality. Their wireless freedom, lightweight portability, waterproof and sweatproof properties, good stability, and ease of use make them popular among young people.

[0003] With the development of technology, there are more and more types of sports Bluetooth headphones, mainly including: bone conduction headphones, air conduction headphones, in-ear headphones, neckband headphones, and over-ear headphones.

[0004] Among them, over-ear Bluetooth headphones are highly favored by young people today due to their excellent sound quality, wearing comfort, noise cancellation, battery life, diverse and stylish designs, and signal stability. However, they still have some shortcomings when used as sports Bluetooth headphones:

[0005] 1. During exercise, users' hands will generally sweat. When controlling the headphones using traditional touch or pressing methods, it will not only contaminate the headphones, but may also cause sensitivity issues, which is not conducive to use during exercise.

[0006] 2. To improve comfort, the earcups of over-ear Bluetooth headphones cover or wrap around the user's ears. At the same time, to ensure noise reduction and sound isolation, the earcups are usually made of non-breathable materials. This makes the ears very prone to sweating during exercise, and the sweat does not evaporate easily, reducing wearing comfort.

[0007] 3. Although over-ear Bluetooth headphones offer high stability, their headband design is generally a semi-circular structure. Since the human head is not a regular sphere and the size of the head varies from person to person, the non-adjustable semi-circular structure leads to significant differences in comfort when different people wear the same headphones, making it impossible to adjust the wearing structure to suit individual needs. Summary of the Invention

[0008] The purpose of this invention is to provide a wearable gesture recognition sports Bluetooth headset that can be adjusted to fit one's head shape according to individual needs, without completely covering the head surface. It can also improve heat dissipation between the head, earcups, and ears, thereby enhancing wearing comfort. Through gesture control, it improves ease of use and control accuracy.

[0009] The specific technical solution adopted by this invention is as follows:

[0010] A wearable gesture recognition sports Bluetooth headset includes a headband, a telescopic frame rotatably mounted at the bottom of the headband, an earphone shell movably mounted in the telescopic frame, and ear cup cotton embedded in the inner side of the earphone shell.

[0011] Also includes:

[0012] The movable support pad has an elastic airbag and a positioning plate fixedly installed on its top surface. The positioning plate is slidably installed on the top of the headband through a positioning mechanism, which is used to adaptively adjust the movable support pad to wrap around the head. One side of the elastic airbag is connected to a ventilation hose, which passes through the headband and extends into the earphone shell, so as to accelerate the airflow between the internal space of the earmuff and the outside air for heat dissipation.

[0013] A rotating support shaft is rotatably connected between the head beam and the telescopic frame. A suspension mechanism and an adjustment mechanism are provided between the rotating support shaft and the telescopic frame to reduce the relative vibration amplitude between the head beam and the telescopic frame, so as to reduce the impact of the relative movement of the head beam and the telescopic frame on the user's head.

[0014] The gesture recognition system includes an image acquisition module, an image preprocessing module, an image recognition module, and an instruction execution module. A PCB is embedded in the outer side of the earphone shell, and the gesture recognition system is integrated into the PCB. The image acquisition module includes a camera and an infrared LED mounted on the PCB, so as to control the Bluetooth earphone by acquiring user gestures through the camera and the infrared LED.

[0015] As a preferred embodiment, the positioning mechanism includes an arc-shaped through groove at the top of the head beam, an arc-shaped side groove at the outer periphery of the arc-shaped through groove, a limiting track at the side wall of the arc-shaped side groove, and a positioning wing plate integrally formed on the side wall of the positioning support plate. The elastic airbag is placed through the arc-shaped through groove, the positioning wing plate is slidably embedded in the limiting track, the top surface of the arc-shaped side groove is provided with positioning grooves at equal intervals, and the bottom surface of the positioning support plate is integrally formed with locking teeth that are adapted to the positioning grooves.

[0016] As a preferred embodiment, one end of the ventilation hose extending into the earphone shell wraps around the outer surface of the wire extending into the earphone shell, and a gap for airflow is provided between the hose and the wire.

[0017] As a preferred embodiment, the earphone shell and the earmuff body are integrally formed with an outer enclosure shell and an inner support shell, and both the outer enclosure shell and the inner support shell are provided with honeycomb ventilation holes on the side near the rotating support shaft.

[0018] As a preferred embodiment, the inner surface of the earmuff cotton body is surrounded and embedded with a honeycomb cotton body that is embedded between the outer enclosure shell and the inner support shell. The honeycomb cotton body is wrapped around the outer surface of the inner support shell, and its ends are embedded at the angle between the outer enclosure shell and the inner support shell to form a breathable layer.

[0019] As a preferred embodiment, the adjustment mechanism includes an inner positioning ring sleeved between the rotating support shaft and the outer side of the top of the telescopic frame, and an inner sliding groove formed on the inner side of the top of the telescopic frame. The inner positioning ring has a protruding post integrally formed on its side that is embedded in the hollow part of the telescopic frame. Floating positioning grooves are equidistantly formed on the inner wall of the inner sliding groove. One end of the rotating support shaft is embedded in the inner sliding groove, and a limiting post that matches the floating positioning groove is integrally formed on its inner side. The width of the limiting post is smaller than the width of the floating positioning groove, so as to form a floating space between the two.

[0020] As a preferred embodiment, the suspension mechanism includes a floating spring fixedly installed in the two arms at the top of the telescopic frame, a restraining rope passing through the two arms of the telescopic frame, and a miniature pulley rotatably installed at the top of the two arms of the telescopic frame. The end of the restraining rope is fixedly attached to the top of the floating spring, and the restraining rope is wrapped around and attached to the lower surface of the rotating support shaft and the miniature pulley.

[0021] As a preferred embodiment, the levitation mechanism further includes an upper levitation magnet fixedly embedded in the inner wall of the top of the telescopic frame and a lower levitation magnet fixedly installed on the upper surface of the rotating support shaft, wherein the upper levitation magnet and the lower levitation magnet have the same polarity on opposite sides.

[0022] As a preferred embodiment, the outer side of the earphone shell is integrally formed with a rectangular groove, the PCB is embedded in the rectangular groove, and a filter plate flush with the outer side of the earphone shell is embedded in the rectangular groove covering the PCB.

[0023] As a preferred embodiment, the image acquisition module is used to acquire analog video signals, convert them into digital signals, and send them to the image preprocessing module for subsequent processing;

[0024] The image preprocessing module is used for caching, framing, and preprocessing gesture images, and sends the preprocessed data to the image recognition module;

[0025] The image recognition module is used for gesture segmentation, gesture feature extraction and recognition, and sends the recognition results to the instruction execution module.

[0026] The instruction execution module is used to set corresponding control instructions for each gesture and to transmit the control instructions to the Bluetooth headset based on the recognition results of the image recognition module.

[0027] The technical effects achieved by this invention are as follows:

[0028] This invention incorporates a gesture recognition system, allowing users to control Bluetooth earphones by waving their hands on either side of the earphone shell during exercise. Compared to traditional touch or press methods, this is more convenient and faster, avoids accidental touches, improves accuracy, and prevents sweat stains from contaminating the earphones, ensuring cleanliness and making future wear easier.

[0029] This invention, by incorporating movable support pads, allows users to adjust the wearing structure according to their head shape, finding a suitable support point for the Bluetooth headset. This ensures wearing comfort and the headset's adaptability to different users. Furthermore, by using elastic airbags in conjunction with positioning plates, during exercise, the relative forces of movement not only cushion the inertial impact of the headband on the head through the elastic airbags, but also continuously compress and restore the elastic airbags, ensuring heat dissipation from the ears, reducing sweat production, and evaporating sweat in a timely manner, thus improving wearing comfort.

[0030] This invention, through the combination of a floating spring, a restraining rope, and upper and lower suspending magnets, utilizes the relative elastic force generated by the stretched floating spring to balance the downward inertial force during user movement. Simultaneously, the repulsive force between the lower and upper suspending magnets balances the upward inertial force. This reduces the impact of the headband and telescopic frame on the user's head and ears during significant movements, thereby lessening the weight's effect on the head and improving wearing comfort. While ensuring noise reduction and stable wear, it minimizes the impact of weight on wearing comfort, making it suitable for wider adoption by various groups. Attached Figure Description

[0062] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0063] like Figures 1-16 As shown, a wearable gesture recognition sports Bluetooth headset includes a headband 1, a telescopic frame 2 rotatably mounted at the bottom of the headband 1, an earphone shell 3 movably mounted within the telescopic frame 2, and earcups 4 embedded in the inner side of the earphone shell 3. An adjustable movable support pad 5 is installed on the headband 1 to allow it to be adjusted according to different head shapes. A rotating shaft 6 is rotatably connected between the headband 1 and the telescopic frame 2, allowing the headband 1 and the telescopic frame 2 to rotate and fold together. The Bluetooth headset is equipped with a gesture recognition system 7, allowing users to control the Bluetooth headset to perform corresponding functions through gestures.

[0064] In this embodiment, the headband 1 adopts a semi-circular U-shaped structure, and the telescopic frame 2 adopts a ring-shaped hollow structure. A U-shaped ring-shaped hollow telescopic adjustment groove is formed on its top, and support arms are formed on both sides of the groove. At the same time, the earphone shell 3 is movably embedded in the circular hollow frame at the bottom of the telescopic frame 2, so that the earphone shell 3 can swing 360° relative to each other in the circular hollow frame, thereby allowing the ear cup cotton body 4 to better fit the skin surface around the user's ears. Meanwhile, the ear cup cotton body 4 is made of memory foam and wrapped with protein leather on the outer surface to ensure the noise reduction function.

[0065] See attached document Figures 1-2 as well as Figures 5-8 To facilitate adjustment of the movable support pad 5, an arc-shaped through groove 11 is provided at the top of the headband 1, and an arc-shaped side groove 13 is provided on the outer periphery of the arc-shaped through groove 11. A limiting track 14 is provided on the side wall of the arc-shaped side groove 13. A positioning support plate 51 is fixedly installed on the top surface of the movable support pad 5, and a positioning wing plate 53 is integrally formed on the side wall of the positioning support plate 51. The positioning wing plate 53 is slidably embedded in the limiting track 14. At the same time, positioning grooves 15 are provided at equal intervals on the top surface of the arc-shaped side groove 13, and a locking tooth (not shown in the figure) is integrally formed on the bottom surface of the positioning support plate 51 to match the positioning groove 15. The movable support pad 5 can be pushed between the arc-shaped side groove 13 and the limiting track 14 to adjust its position relative to the headband 1. The locking tooth and the positioning groove 15 are used to adjust and position it to fit different head shapes, so that the most suitable Bluetooth headset support point can be found on the top of the head, improving wearing comfort.

[0066] In this embodiment, two sets of movable support pads 5 are symmetrically arranged, allowing users to select two suitable support points on both sides of their head, thereby reducing the contact area with the head. It does not need to completely cover the user's head, which is beneficial for heat dissipation during exercise and prevents excessive sweat from contaminating the headphone surface. The upper surface of the movable support pads 5 uses the same hard material as the positioning plate 51 and the headband 1, while the part in contact with the head uses a memory foam outer woven layer design to ensure comfort and breathability.

[0067] Of course, in other embodiments, at least two sets can be selected according to the size of the active support pad 5, and the material can be selected according to specific design requirements.

[0068] Furthermore, the top surface of the positioning support plate 51 is evenly provided with anti-slip grooves 54 to increase the relative friction between the fingers and the positioning support plate 51, making it more stable for the user to move the movable support pad 5 using the positioning support plate 51, and avoiding slippage.

[0069] Secondly, in other embodiments, to facilitate the adjustment of the movable support pad 5, the positioning wing plate 53 and the arc-shaped side groove 13 are connected by magnetic attraction instead of the teeth and the positioning groove 15. Specifically, magnets with opposite polarities are pasted on the bottom surface of the positioning wing plate 53 and the arc-shaped side groove 13 respectively, and an anti-slip rubber layer is wrapped around them. The positioning is adjusted by using the magnetic attraction and the friction between the anti-slip rubber layer. In actual production, the appropriate method can be selected according to specific needs.

[0070] Please refer to the appendix again. Figures 1-2 as well as Figures 5-8To ensure heat dissipation between the ear and the earcup body 4, an elastic airbag 52 is fixedly installed between the movable support pad 5 and the positioning plate 51. One side of the elastic airbag 52 is connected to a ventilation hose 55, which passes through the headband 1 and extends into the earphone shell 3. At the same time, one end of the ventilation hose 55 extending into the earphone shell 3 wraps around the outer surface of the wire extending into the earphone shell 3, and a gap for airflow is provided between the hose and the wire (as shown in the attached figure). Figure 7 As shown in the diagram, the elastic airbag 52 is inserted through the arc-shaped groove 11 so as not to affect the adjustment and movement of the movable support pad 5. In this way, during the user's exercise, the movement of the user's limbs will synchronously drive the relative movement of the headband 1 and the telescopic frame 2, thereby driving the relative movement between the positioning support plate 51 and the movable support pad 5, continuously compressing and restoring the elastic airbag 52. This allows air to be continuously drawn in and out between the earmuff body 4 and the ear through the ventilation hose 55. In turn, the elastic airbag 52 accelerates the airflow between the internal space of the earmuff body 4 and the outside air to dissipate heat, reduce the production of sweat in the ear, and evaporate the sweat to the outside, ensuring wearing comfort.

[0071] Furthermore, the earphone shell 3 and the earcup body 4 are integrally formed with an outer surrounding shell 36 and an inner support shell 37. Both the outer surrounding shell 36 and the inner support shell 37 have honeycomb ventilation holes 38 extending through them on the side near the rotating support shaft 6. Simultaneously, a honeycomb body 41 is embedded around the inner surface of the earcup body 4, enclosing and embedding between the outer surrounding shell 36 and the inner support shell 37. The honeycomb body 41 is wrapped around the outer surface of the inner support shell 37, with its end embedded at the angle between the outer surrounding shell 36 and the inner support shell 37 (as shown in the attached diagram). Figure 15 As shown in the figure, a breathable breathing layer is formed to ensure that the airflow between the earmuff cotton body 4 and the ear can be quickly exchanged with the outside world through the honeycomb cotton body 41 and the honeycomb ventilation holes 38. At the same time, the honeycomb cotton body 41 and the honeycomb ventilation holes 38 ensure breathability while the honeycomb structure can effectively absorb the noise transmitted from the outside. In addition, the honeycomb ventilation holes 38 are located away from the area where the sound is concentrated, so as not to reduce the sound insulation effect and ensure the noise reduction performance.

[0072] See attached document Figures 2-3 as well as Figures 9-10The head beam 1 has a through hole 12 at its bottom end that matches the top opening of the telescopic frame 2. A rotating support shaft 6 is installed between the through hole 12 and the top opening of the telescopic frame 2. An outer reinforcing plate 61 is fixedly installed on the inner side wall of the bottom end of the head beam 1 to enhance the support strength. An inner positioning ring 63 is sleeved between the rotating support shaft 6 and the outer side of the top of the telescopic frame 2. An inner sliding groove 21 that matches the top of the telescopic frame 2 is provided on the inner side of the top. A protruding post that is integrally formed on the side of the inner positioning ring 63 and embedded in the opening of the telescopic frame 2 allows the telescopic frame 2 to slide up and down along a predetermined track to adjust the height of the earmuff cotton body 4 to suit different users. Floating positioning grooves 22 are provided at equal intervals on the inner wall of the inner sliding groove 21. One end of the rotating support shaft 6 is embedded in the inner sliding groove 21, and a limiting post (not shown in the figure) that matches the floating positioning groove 22 is integrally formed on the inner side. The limiting post and the floating positioning groove 22 cooperate to complete the positioning after adjustment.

[0073] See attached document Figures 2-3 as well as Figures 9-15 The telescopic frame 2 has an inner mounting cavity 23 inside each of its two top arms. A floating spring 25 is fixedly installed at the bottom of the inner mounting cavity 23, and a restraining rope 27 is threaded between the two arms of the telescopic frame 2. At the same time, a miniature pulley 26 is rotatably installed in the inner mounting cavity 23 at the top of the two arms of the telescopic frame 2. The end of the restraining rope 27 is fixedly bolted to the top of the floating spring 25. The restraining rope 27 is wrapped around and attached to the lower surface of the rotating support shaft 6 and the miniature pulley 26 (as shown in the attached figure). Figure 14 As shown, when the user adjusts the height of the telescopic frame 2, the rotating support shaft 6 moves downward relative to the telescopic frame 2, thereby pushing the restraining rope 27 to pull the floating spring 25 and generate a relative elastic force. After the adjustment is completed, the positioning is completed by the cooperation of the limiting post and the floating positioning groove 22 to prevent it from rebounding. At the same time, the width of the limiting post is smaller than the width of the floating positioning groove 22 to form a floating space between the two. When the user moves, when the head beam 1 and the telescopic frame 2 move relative to each other, the rotating support shaft 6 and the telescopic frame 2 will also move relative to each other and reciprocate relative to each other in the floating space formed by the floating positioning groove 22. During the shaking process, the downward inertial force is balanced by the upward relative elastic force generated by the lifting floating spring 25 through the restraining rope 27 on the rotating support shaft 6, thereby buffering the downward inertial impact force.

[0074] Furthermore, an upper levitation magnet 24 is fixedly installed on the inner wall of the cavity 23 at the top of the telescopic frame 2, and a lower levitation magnet 62 is fixedly installed on the upper surface of the rotating support shaft 6. The upper levitation magnet 24 and the lower levitation magnet 62 have the same polarity on opposite sides. When they approach each other, they will generate a downward relative repulsive force on the rotating support shaft 6. In the static state, their relative repulsive force can be balanced by the upward pushing force generated by the lifting floating spring 25 through the restraining rope 27 on the rotating support shaft 6, thereby maintaining the stability between the telescopic frame 2 and the headband 1 when the headphones are not in use. At the same time, the limiting post and the floating positioning groove 22 can also limit it. When the user moves, the rotating support shaft 6 and the telescopic frame 2 will also move relative to each other. The upward force generated by pushing the rotating support shaft 6 will cause the lower levitation magnet 62 and the upper levitation magnet 24 to move closer together, thereby increasing the repulsive force between them with the same polarity. This force can be balanced by the repulsive force between the lower levitation magnet 62 and the upper levitation magnet 24 with the same polarity.

[0075] In this embodiment, since the telescopic frame 2 is semi-circular, both the upper levitation magnet 24 and the lower levitation magnet 62 are semi-circular D-shaped magnets. The two are concentric semi-circular arcs. The inner arc surface of the upper levitation magnet 24 and the outer arc surface of the lower levitation magnet 62 have the same magnetic poles to achieve the above purpose. At the same time, when the two are fully attached, they are all embedded in the top of the inner mounting cavity 23 to ensure the overall aesthetics.

[0076] Of course, in other embodiments, the top of the telescopic frame 2 can be set in a rectangular shape, and both the upper levitation magnet 24 and the lower levitation magnet 62 can be ordinary bar magnets. The selection can be made according to the specific needs in actual application.

[0077] According to the above structure, when a user wears the Bluetooth headset and engages in vigorous exercise, the shaking caused by the headset can be balanced by the relative elastic force generated by the tension of the floating spring 25, which balances the downward inertial force. The repulsive force between the lower and upper suspended magnets 62 and 24 can balance the upward inertial force, thereby reducing the impact of the headband 1 and telescopic frame 2 on the user's head and ears during vigorous exercise. This reduces the impact of weight on the head, improves wearing comfort, and minimizes the impact of weight on wearing comfort while ensuring noise reduction and wearing stability.

[0078] See attached document Figure 16 The gesture recognition system 7 includes an image acquisition module 71, an image preprocessing module 72, an image recognition module 73, and an instruction execution module 74. It acquires the user's gesture information, preprocesses and recognizes it, and then outputs execution instructions to realize the control of the Bluetooth headset through gestures.

[0079] The image acquisition module 71 is used to acquire analog video signals, convert them into digital signals, and send them to the image preprocessing module 72 for further processing.

[0080] The image preprocessing module 72 is used for caching, framing, and preprocessing gesture images, determining whether the gesture is static or dynamic. If it is dynamic, a video segment is transmitted; if it is static, an image is transmitted. The preprocessed data is then sent to the image recognition module 73.

[0081] The image recognition module 73 is used for gesture segmentation, gesture feature extraction and recognition. It obtains frame data based on the transmitted image or video. Each frame contains all the information about hand movements, such as all hands, fingers, endpoint objects, tools, gestures and their positions, speeds, directions, rotation angles, etc., and sends the recognition results to the instruction execution module 74.

[0082] The instruction execution module 74 is used to set corresponding control instructions for each gesture action, and store the corresponding gesture information and corresponding control instructions in the database. Based on the recognition result of the image recognition module 73, it matches the corresponding control instructions and transmits the control instructions to the Bluetooth headset, thereby completing the function operation of the Bluetooth headset through gestures.

[0083] See attached document Figure 2 , Figure 4 by Figure 16 The outer side of the earphone shell 3 is integrally formed with a rectangular groove 31, and a PCB 32 is embedded in the rectangular groove 31. At the same time, the gesture recognition system 7 is integrated into the PCB 32. The image acquisition module 71 includes a camera 34 and an infrared LED 35 mounted on the PCB 32. The camera 34 and the infrared LED 35 are used to collect user gestures to control the Bluetooth earphone. When using the earphone, the user can control the Bluetooth earphone by waving gestures on both sides of the earphone shell 3. Compared with the traditional touch or press method for earphone control, it is more convenient and faster, while avoiding accidental touches, improving accuracy, and preventing the earphone from being contaminated by sweat stains, thus ensuring the cleanliness of the earphone and providing convenience for future wear.

[0084] In this embodiment, two cameras 34 are provided, and three infrared LEDs 35 are installed on both sides of the cameras and between the two cameras. The cameras 34 are high frame rate grayscale infrared cameras with wide-angle lenses, which can improve the recognition range. The horizontal field of view is 140° and the vertical field of view is 120°. At the same time, the matching infrared LEDs 35 can ensure the recognition accuracy in different lighting environments, thereby reducing the amount of computational data and improving the algorithm speed.

[0085] Of course, in other embodiments, a suitable model and an appropriate number of cameras 34 and infrared LEDs 35 can be selected according to different recognition accuracies.

[0086] Furthermore, to improve the aesthetics of the Bluetooth headset and ensure the accuracy of image acquisition, this embodiment incorporates a filter plate 33, flush with the outer surface of the headset shell 3, embedded within the rectangular slot 31 and covered by a PCB 32. This filter plate filters out noise waves with wavelengths exceeding 940 nanometers, allowing only infrared light waves generated by the built-in infrared LED 35 to pass through. This allows the sensor to receive cleaner infrared images, reducing interference from complex backgrounds on the recognition results, thereby enhancing the recognition effect, ensuring recognition stability, and enabling users to precisely and quickly control the Bluetooth headset with gestures during exercise.

[0087] The working principle of this invention is as follows: First, when wearing the Bluetooth headset, the movable support pad 5 can be moved relative to the headband 1 to adjust its position relative to the headband 1 so as to adapt to different head shapes and find the most suitable Bluetooth headset support point on the top of the head. At the same time, the height of the telescopic frame 2 can be adjusted relative to the headband 1 to adapt to different users with different ear heights, so that the earmuff cotton body 4 can perfectly cover the ears.

[0088] Secondly, during exercise, the Bluetooth headset can be controlled by waving gestures on both sides of the earphone shell 3. After waving a predetermined gesture, the camera 34 can receive the corresponding gesture. After the signal is processed by the image acquisition module 71, the image preprocessing module 72, the image recognition module 73 and the instruction execution module 74, the Bluetooth headset can be controlled to perform the corresponding function operation.

[0089] Finally, during exercise, the user's limb movements will synchronously drive the relative movement of the headband 1 and the telescopic frame 2, thus causing the positioning support plate 51 and the movable support pad 5 to move relative to each other, continuously compressing and restoring the elastic airbag 52. This allows air to be continuously drawn in and out between the earmuff cotton body 4 and the ear through the ventilation hose 55, and then exchanged with the outside air through the honeycomb cotton body 41 and honeycomb ventilation holes 38, ensuring heat dissipation of the ear, reducing sweat production, and evaporating sweat in time, thereby improving wearing comfort.

[0090] Furthermore, when the user adjusts the height of the telescopic frame 2, the rotating support shaft 6 moves relative to the telescopic frame 2, thereby pushing the restraint rope 27 to pull the floating spring 25, generating a relative elastic force. At the same time, the upper suspending magnet 24 and the lower suspending magnet 62 move away from each other, reducing their interaction force. Under the action of the limiting post and the floating positioning groove 22, they are kept in relative positions. During the movement, when the headband 1 and the telescopic frame 2 move relative to each other, the rotating support shaft 6 and the telescopic frame 2 will also move relative to each other and reciprocate relative to each other within the range of the floating positioning groove 22. During the shaking, the downward force is balanced by the relative elastic force generated by the pull, while the upward force is balanced by the repulsive force of the same pole between the lower suspending magnet 62 and the upper suspending magnet 24. This reduces the impact of the headband 1 and the telescopic frame 2 on the patient's head and ears during the user's large-scale movements, thereby reducing the impact of weight on the head and improving wearing comfort.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
