Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent wearable devices, and in particular relates to a wearable gesture recognition sports Bluetooth headset. Background Art

[0002] Sports Bluetooth headsets are specially designed for sports and fitness. Compared with traditional wired headsets and ordinary single-ear Bluetooth headsets for business calls, they have significantly improved waterproof performance, anti-falling performance, sound quality, etc. They are loved by young people because of their wireless freedom, lightness and portability, waterproof and sweat-proof, good stability and easy operation.

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

[0004] Among them, head-mounted Bluetooth headsets are very popular among young people at this stage due to their excellent sound quality, wearing comfort, noise reduction effect, battery life, design diversity and fashion sense, and signal stability. However, there are still some defects when using them as sports Bluetooth headsets: 1. When users exercise, their hands will sweat. Therefore, when controlling the earphones by traditional touch or press methods, it will not only pollute the earphones, but also may cause sensitivity problems, which is not conducive to users using them during exercise; 2. In order to improve the comfort of head-mounted Bluetooth headsets, the earmuffs are covered on the user's ears or wrapped on the user's ears. At the same time, in order to ensure noise reduction and sound insulation, the earmuffs are generally made of airtight materials. In this way, the ears are prone to sweating during exercise, and the sweat is not easy to evaporate, which reduces the wearing comfort; 3. Although head-mounted Bluetooth headsets have high wearing stability, their headband design is generally a semi-circular structure. Since the human head is not a regular sphere and the head size varies from person to person, the non-adjustable semi-circular structure leads to a large difference in comfort when different people wear the same headset, and it is impossible to adjust the appropriate wearing structure according to their needs. Summary of the invention

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] like Figure 1-Figure 16 As shown, a wearable gesture recognition sports Bluetooth headset comprises a head beam 1, a telescopic frame 2 rotatably mounted on the bottom end of the head beam 1, an earphone shell 3 movably mounted in the telescopic frame 2, and an earmuff cotton body 4 embedded in the inner side of the earphone shell 3, and an adjustable movable support pad 5 is installed on the head beam 1 so that it can be adjusted according to different head shapes, and a rotating support shaft 6 is rotatably connected between the head beam 1 and the telescopic frame 2 so that the head beam 1 and the telescopic frame 2 can be rotated and folded, and a gesture recognition system 7 is loaded in the Bluetooth headset, and the user can control the Bluetooth headset to perform corresponding functional operations through gestures.

[0023] Among them, in this embodiment, the headband 1 adopts a semicircular U-shaped structure, the telescopic frame 2 adopts an annular hollow structure, a U-shaped annular hollow telescopic adjustment groove is formed on the 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° relatively in the circular hollow frame, so that the earmuff cotton body 4 can better fit the skin surface around the user's ear. At the same time, the earmuff cotton body 4 is made of memory foam and wrapped with protein leather on the outer surface to ensure the noise reduction function.

[0024] Refer to the attached Figure 1-Figure 2 as well as Figure 5-Figure 8 In order to facilitate the adjustment of the movable support pad 5, an arc-shaped through groove 11 is provided on the top of the head beam 1, and an arc-shaped side groove 13 is provided on the outer periphery of the arc-shaped through groove 11, and 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, and the positioning wing plate 53 is slidably embedded in the limiting track 14. At the same time, positioning grooves 15 are equidistantly provided on the top surface of the arc-shaped side groove 13, and a latch tooth (not shown in the figure) matched with the positioning groove 15 is integrally formed on the bottom surface of the positioning support plate 51. 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 head beam 1, and the latch tooth is used to cooperate with the positioning groove 15 to adjust the positioning so that it can adapt to different head shapes, and the most suitable Bluetooth headset support point can be found on the top of the head to improve wearing comfort.

[0025] In this embodiment, two groups of movable support pads 5 are symmetrically arranged, and two suitable support points can be selected on both sides of the user's head, thereby reducing the contact area with the head. It is not necessary to completely cover the user's head, which is beneficial to the heat dissipation of the head during exercise and is not easy to produce too much sweat and pollute the surface of the earphone. The upper surface of the movable support pad 5 is made of the same hard material as the positioning support plate 51 and the headband 1, and the part in contact with the head is designed with a memory foam wrapped in a woven layer to ensure comfort and breathability.

[0026] Of course, in other embodiments, at least two groups can be selected according to the size of the movable support pad 5, and the material can be selected according to specific design requirements.

[0027] Furthermore, anti-skid grooves 54 are evenly formed on the top surface of the positioning support plate 51 to increase the relative friction between the fingers and the positioning support plate 51, so that the user can move the movable support pad 5 more stably by using the positioning support plate 51 to avoid slipping.

[0028] Secondly, in other embodiments, in order to facilitate the adjustment of the movable support pad 5, a magnetic attraction method is used between the positioning wing plate 53 and the arc-shaped side groove 13 instead of the latch teeth and the positioning groove 15. Specifically, magnets with opposite polarities are respectively pasted on the bottom surface of the positioning wing plate 53 and the arc-shaped side groove 13, and a non-slip rubber layer is wrapped at the same time. The magnetic attraction force and the friction force between the non-slip rubber layer are used to adjust the positioning. The actual production can be selected according to specific needs.

[0029] Again refer to the attached Figure 1-Figure 2 as well as Figure 5-Figure 8 In order to ensure the heat dissipation between the ear and the earmuff cotton body 4, an elastic airbag 52 is fixedly installed between the movable support pad 5 and the positioning support plate 51. One side of the elastic airbag 52 is connected to a ventilation hose 55, which is inserted into the headband 1 and extends into the earphone shell 3. At the same time, one end of the ventilation hose 55 extends to the inside of the earphone shell 3 and is wrapped around the outer surface of the wire extending into the earphone shell 3, and a gap for air flow is set between the wire (such as the attached Figure 7 As shown), the elastic airbag 52 is placed through the arc groove 11 so that it will not affect the adjustment and movement of the movable support pad 5; in this way, when the user is exercising, the movement of the user's limbs will synchronously drive the relative movement of the head beam 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, so that air is continuously drawn and exhausted between the earmuff cotton body 4 and the ear through the ventilation hose 55, and then the elastic airbag 52 is used to accelerate the air flow between the internal space of the earmuff cotton body 4 and the outside to dissipate heat, reduce the production of ear sweat, and evaporate the produced sweat to the outside to ensure wearing comfort.

[0030] Furthermore, the earphone shell 3 and the earmuff cotton body 4 are integrally formed with an outer surrounding shell 36 and an inner supporting shell 37 at the joint end, and honeycomb ventilation holes 38 are penetrated through the outer surrounding shell 36 and the inner supporting shell 37 on one side close to the rotating support shaft 6. At the same time, the inner surface of the earmuff cotton body 4 is surrounded and embedded with a honeycomb cotton body 41 wrapped and embedded between the outer surrounding shell 36 and the inner supporting shell 37, and the honeycomb cotton body 41 is wrapped around the outer surface of the inner supporting shell 37, and the end is embedded in the angle between the outer surrounding shell 36 and the inner supporting shell 37 (as shown in the attached figure). Fig.15 As shown), 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 air holes 38. At the same time, the arrangement of the honeycomb cotton body 41 and the honeycomb air holes 38 ensures ventilation. The honeycomb structure can well absorb the noise transmitted from the outside world. At the same time, the honeycomb air holes 38 are arranged away from the area where sound is concentrated, so as not to reduce the sound insulation effect and ensure the noise reduction performance.

[0031] See attached Figure 2-Figure 3 as well as Figure 9-10 The bottom end of the head beam 1 is penetrated by a rotating through hole 12 that is compatible with the hollow top of the telescopic frame 2, and the rotating support shaft 6 is installed between the rotating through hole 12 and the hollow top of the telescopic frame 2. At the same time, an outer reinforcing plate 61 that strengthens the supporting strength is fixedly installed on the inner side wall of the bottom end of the head beam 1, and an inner positioning ring 63 is sleeved between the rotating support shaft 6 and the outer side surface of the top of the telescopic frame 2, and an inner slide groove 21 that is compatible with it is opened on the inner side surface of the top of the telescopic frame 2. By integrally forming a convex column embedded in the hollow part of the telescopic frame 2 on the side of the inner positioning ring 63, the telescopic frame 2 can be telescopically slid up and down along a predetermined track to adjust the height of the earmuff cotton body 4 to adapt to different users; and then floating positioning grooves 22 are equidistantly opened on the inner wall of the inner slide groove 21, and one end of the rotating support shaft 6 is embedded in the inner slide groove 21, and a limiting column (not shown in the figure) that is compatible with the floating positioning groove 22 is integrally formed on the inner side surface, and the limiting column is used to cooperate with the floating positioning groove 22 to complete the positioning after adjustment.

[0032] See attached Figure 2-Figure 3 as well as Figure 9-Figure 15 The two arms at the top of the telescopic frame 2 are provided with an inner mounting cavity 23, a floating spring 25 is fixedly installed at the bottom of the inner mounting cavity 23, and a binding rope 27 is passed between the two arms of the telescopic frame 2. At the same time, a micro pulley 26 is rotatably installed in the inner mounting cavity 23 at the top of the two arms of the telescopic frame 2, and the end of the binding rope 27 is fixedly bolted to the top of the floating spring 25. At the same time, the binding rope 27 surrounds and fits on the lower surface of the rotating support shaft 6 and the micro pulley 26 (as shown in the attached Fig.14As shown in the figure, 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 binding rope body 27 to pull up the floating spring 25 to generate a relative elastic force. After the adjustment is completed, the positioning is completed by cooperating with the limit column and the floating positioning groove 22 to prevent it from rebounding. At the same time, the width of the limit column is smaller than the width of the floating positioning groove 22 to form a suspended space between the two. When the user exercises, the headband 1 and the telescopic frame 2 move relative to each other, and the rotating support shaft 6 and the telescopic frame 2 also move relative to each other, and reciprocate relative to each other in the suspended 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 on the rotating support shaft 6 through the binding rope body 27, thereby buffering the downward inertial impact force.

[0033] Furthermore, an upper suspension magnet 24 is fixedly mounted on the inner wall of the cavity 23 installed in the top of the telescopic frame 2, and a lower suspension magnet 62 is fixedly mounted on the upper surface of the rotating support shaft 6, and the upper suspension magnet 24 and the lower suspension magnet 62 have the same polarity on one side relative to each other. When the two are close to each other, a relative repulsive force downward is generated on the rotating support shaft 6, and in a static state, the relative repulsive force can be balanced by the upward thrust generated by the lifting floating spring 25 on the rotating support shaft 6 through the binding rope body 27, thereby maintaining the stability between the telescopic frame 2 and the headband 1 when the earphone is not in use, and the limit column and the floating positioning groove 22 can also limit it; when the user is exercising, the rotating support shaft 6 and the telescopic frame 2 will also produce relative movement, and the force generated to push the rotating support shaft 6 upward will make the lower suspension magnet 62 and the upper suspension magnet 24 approach each other continuously, thereby increasing the repulsive force of the same polarity between the two, and then can be balanced by the repulsive force of the same polarity between the lower suspension magnet 62 and the upper suspension magnet 24.

[0034] In this embodiment, since the telescopic frame 2 is in a semicircular arc shape, the upper suspension magnet 24 and the lower suspension magnet 62 both adopt semicircular D-shaped magnets, and the two are concentric semicircular arcs. The inner arc surface of the upper suspension magnet 24 and the outer arc surface of the lower suspension magnet 62 have the same magnetic pole to achieve the above-mentioned purpose. At the same time, when the two are fully fitted, they are all embedded in the top of the inner mounting cavity 23 to ensure the overall aesthetics.

[0035] Of course, in other embodiments, the top of the telescopic frame 2 can be set to a rectangular shape, and the upper suspension magnet 24 and the lower suspension magnet 62 can both be ordinary bar magnets, which can be selected according to specific needs in actual application.

[0036] According to the above structure, when the user wears the Bluetooth headset and performs large-scale movements, the Bluetooth headsets will shake. The floating spring 25 is pulled up to generate a relative elastic force to balance the downward inertial force of movement, and the repulsive force of the same poles between the lower suspension magnet 62 and the upper suspension magnet 24 can be used to balance the upward inertial force of movement, thereby reducing the inertial 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, improving wearing comfort, and minimizing the impact of weight on wearing comfort while ensuring noise reduction and wearing stability.

[0037] Refer to the attached Fig.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, and collects the user's gesture information, outputs the execution instruction after preprocessing and recognition, and then realizes the control of the Bluetooth headset through gestures.

[0038] 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 subsequent processing.

[0039] The image preprocessing module 72 is used for caching, framing, and preprocessing gesture images, and determines whether the gesture is static or dynamic. If it is dynamic, a video is transmitted; if it is static, an image is transmitted; and the preprocessed data is sent to the image recognition module 73.

[0040] 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, that is, each frame of data contains all 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.

[0041] The instruction execution module 74 is used to set corresponding control instructions for each gesture action, and store the corresponding gesture information and the corresponding control instructions in the database, match the corresponding control instructions according to the recognition results of the image recognition module 73, convey the control instructions to the Bluetooth headset, and then complete the functional operation of the Bluetooth headset through gestures.

[0042] Refer to the attached Figure 2 , Figure 4 by Fig.16A rectangular groove 31 is integrally formed on the outer side of the earphone shell 3, and a PCB 32 is embedded in the rectangular groove 31. At the same time, the gesture recognition system 7 is integrated in the PCB 32. The image acquisition module 71 includes a camera 34 and an infrared LED 35 installed on the PCB 32. The camera 34 and the infrared LED 35 are used to collect user gestures to control the Bluetooth headset. When in use, the user can control the Bluetooth headset by waving gestures on both sides of the earphone shell 3. Compared with the traditional touch or press method to control the headset, it is more convenient and quick, and it can avoid accidental touch and improve accuracy. In addition, the headset will not be contaminated by sweat on the hands, which ensures the cleanliness of the headset and provides convenience for future wearing.

[0043] Among them, in this embodiment, two cameras 34 are provided, and three infrared LEDs 35 are installed on both sides thereof and in the gap between them. The camera 34 is a high frame rate grayscale infrared camera with a wide-angle lens, which can improve the recognition range. Its horizontal field of view angle reaches 140° and its vertical field of view angle reaches 120°. At the same time, matching the infrared LEDs 35 can ensure the recognition accuracy in different light environments, so as to reduce the amount of computing data and improve the algorithm speed.

[0044] Of course, in other embodiments, suitable models and appropriate numbers of cameras 34 and infrared LEDs 35 may be selected according to different recognition accuracies.

[0045] Furthermore, in order to improve the aesthetics of the Bluetooth headset and ensure the accuracy of image acquisition, the present embodiment covers the PCB 32 in the rectangular groove 31 and embeds a filter plate 33 flush with the outer side of the headset shell 3, which can filter out other clutter with a wavelength other than 940 nanometers and only allow the infrared light waves generated by the built-in infrared LED 35 to enter and exit. In this way, the sensor can receive purer infrared imaging, thereby reducing the interference of complex background on the recognition result, thereby enhancing the recognition effect, ensuring the recognition stability, and allowing the user to accurately and quickly control the Bluetooth headset through gestures during exercise.

[0046] The working principle of the present invention is as follows: first, when wearing the Bluetooth headset, the movable support pad 5 can be moved relative to the head beam 1 to adjust its position relative to the head beam 1 so as to adapt it to different head shapes, and the most suitable Bluetooth headset support point can be found on the top of the head. At the same time, the height of the telescopic frame 2 can be adjusted relative to the head beam 1 to adapt it to the ears of different heights of different users, so that the earmuff cotton body 4 can perfectly cover the ears; Secondly, during the movement, the Bluetooth headset can be controlled by waving gestures on both sides of the headset shell 3. After waving the predetermined gesture, the camera 34 can receive the corresponding gesture, and then after the image acquisition module 71, the image preprocessing module 72, the image recognition module 73 and the instruction execution module 74 perform signal processing, the Bluetooth headset is controlled to perform the corresponding function operation; Finally, during the 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, thereby continuously pumping and exhausting air between the earmuff cotton body 4 and the ear through the ventilation hose 55, and then exchanging gas with the outside air through the honeycomb cotton body 41 and the honeycomb air holes 38, thereby ensuring the heat dissipation of the ear, reducing the production of sweat, and being able to evaporate sweat in time to improve wearing comfort.

[0047] 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 binding rope 27 to pull up the floating spring 25 to generate a relative elastic force. At the same time, the upper suspension magnet 24 and the lower suspension magnet 62 move away from each other, the interaction force is reduced, and under the action of the limit column and the floating positioning groove 22, they are kept in a relative position. During the movement, 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 within the range of the floating positioning groove 22. During the shaking process, the downward force is balanced by the relative elastic force generated by the pulling, and the upward force is balanced by the repulsive force of the same poles between the lower suspension magnet 62 and the upper suspension magnet 24, thereby reducing the impact of the inertia of the head beam 1 and the telescopic frame 2 on the patient's head and ears during the user's large-scale movement, thereby reducing the impact of weight on the head and improving wearing comfort.

[0048] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
