Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a bone conduction headphone with lighting effects. Background Technology

[0002] With the continuous upgrading of residents' sports consumption demands, bone conduction headphones, with their structure that eliminates the need for air transmission and excellent waterproof performance, have become the mainstream audio device for sports scenarios such as swimming, diving, and night running. Their core advantage lies in the fact that they allow both ears to be open when worn, avoiding the discomfort and hygiene problems caused by sweating in in-ear headphones. They also allow users to perceive changes in their surroundings, improving safety during exercise, and can transmit sound normally underwater, making them suitable for water sports such as swimming and shallow diving.

[0003] However, existing bone conduction headphones still have significant functional limitations in practical applications, making it difficult to meet users' core needs in specific scenarios: Lack of or ineffective lighting: In night running scenarios, users need to clearly identify obstacles (such as pebbles and steps) 1-3 meters ahead. However, most existing bone conduction headphones do not integrate lighting functions, requiring users to carry additional equipment such as flashlights, increasing the burden of exercise. Even if some products include lighting structures, the beam angle is often poorly designed (mostly vertically forward, with an angle close to 90 degrees to the horizontal), failing to cover the core area of ​​the ground, resulting in weak lighting effects. In diving scenarios (such as shallow diving within 10 meters), natural waterways are dimly lit. If existing headphones have lighting structures, the light often shines directly into the water ahead, failing to illuminate key observation targets such as reefs and marine life below, thus failing to meet the environmental observation needs during diving.

[0004] Lack of emergency rescue function: During outdoor sports, sudden dangers such as getting lost and getting injured often occur. The internationally recognized "SOS rescue signal (three short flashes of light → three long flashes of light → three short flashes of light, with a cycle of 10 seconds)" is an important means of calling for help. However, existing bone conduction headphones do not integrate this light rescue mode, which cannot provide users with emergency protection and makes it difficult to assist users in obtaining external rescue in emergency situations.

[0005] Insufficient structural design and functional adaptability: If some bone conduction headphones attempt to integrate lighting elements, the limited space inside the unit compartment often leads to a chaotic assembly layout of the lighting elements and the sound unit, and a lack of targeted heat dissipation structure. The heat generated by the lighting elements during operation is prone to accumulate, shortening the lifespan of the elements. Utility Model Content

[0006] To overcome the shortcomings of the prior art, this utility model aims to provide a technical solution that can solve the above problems.

[0007] This invention provides a bone conduction headphone with lighting effects, comprising a headphone body, one end of which is fixedly fitted with a unit compartment having an internal accommodating space. The unit compartment contains independently arranged sound-generating units and light-emitting units; The sound-generating unit is used to generate sound wave vibrations to achieve bone conduction function; The side wall of the unit compartment is provided with a light-emitting channel extending radially therein. The light-emitting units are sequentially assembled in the light-emitting channel from the inside to the outside of the unit compartment. The light-emitting unit includes a lamp board, a lamp bead fixed to one side of the lamp board, and a lens. The lens is sealed and assembled at the outer port of the light-emitting channel extending outward, and the side of the lens away from the light-emitting channel forms an irradiation surface that emits light outward. When the earphone is in the wearing state, the angle between the irradiation surface and the horizontal plane is maintained at 45 to 89 degrees to ensure that the light passing through the lens shines towards the ground.

[0008] Furthermore, when the earphone is in the wearing state, the angle between the irradiation surface and the horizontal plane is maintained at 65-85 degrees to further optimize the illumination range of the light on the ground, so that the light covers the ground area in front of the user.

[0009] Furthermore, when the earphone is in the wearing state, the angle between the irradiation surface and the horizontal plane is maintained at 81 degrees to control the light irradiation area and ensure that the light covers the preset ground area in front of the user.

[0010] Furthermore, the light-emitting unit also includes a heat dissipation component. The side of the lamp panel away from the lamp beads is the back of the lamp panel. One side of the heat dissipation component is tightly attached to the back of the lamp panel, and the other side is tightly attached to the inner wall of the unit compartment, so as to transfer the heat generated by the lamp beads to the unit compartment in sequence through the lamp panel and the heat dissipation component, and dissipate it to the outside through the outer wall of the unit compartment, thereby extending the service life of the lamp beads.

[0011] Furthermore: a heat-conducting baffle is provided at one end of the light-emitting channel facing the inside of the unit compartment. The heat-conducting baffle is either fixedly connected to the inner side wall of the unit compartment or integrally formed with the inner side wall of the unit compartment. The heat dissipation component is sandwiched between the back of the lamp panel and the heat-conducting baffle, and the heat dissipation component is tightly attached to the back of the lamp panel and the heat-conducting baffle respectively, so as to enhance the efficiency of heat transfer from the heat dissipation component to the unit compartment.

[0012] Furthermore: the unit compartment is a hollow container with an internal accommodating space. One side of the unit compartment has an assembly opening that communicates with the accommodating space. The assembly opening is used for the insertion and assembly of the light-emitting unit and the sound-emitting unit. The unit compartment also includes a compartment cover, which is fixedly connected to the assembly opening. A sealing structure is provided between the compartment cover and the assembly opening to form a waterproof and sealed state.

[0013] Furthermore, the earphone body also includes an ear hook connector and an auxiliary module; the ear hook connector is a flexible structure, with one end fixedly connected to the outer wall of the unit compartment and the other end fixedly connected to the outer wall of the auxiliary module; the ear hook connector has a cable channel extending along its length inside, and a cable is threaded through the cable channel, with both ends of the cable being electrically connected to the electrical components in the unit compartment and the electrical components in the auxiliary module, respectively, to realize the signal and power transmission between the two.

[0014] Furthermore, the earphone body also includes a rear hook connector, which is a flexible elongated structure; each end of the rear hook connector is equipped with a set of components, each set of components including an auxiliary module, an ear hook connector and a unit compartment, and the unit compartments in the two sets of components are respectively equipped with a left channel sound unit and a right channel sound unit to achieve binaural synchronous playback function.

[0015] Compared with the prior art, the beneficial effects of this utility model are: ① The lighting function is precisely adapted to the needs of the scene: By integrating the light-emitting unit in the unit compartment and optimizing the angle between the lens illumination surface and the horizontal plane (45~89 degrees, preferably 65~85 degrees, optimal 81 degrees), the light can accurately cover the ground area 1-3 meters in front when running at night and the observation area 0.5-2 meters below when diving. This effectively solves the problem of the lack of lighting or poor effect of existing headphones, eliminating the need for users to carry additional lighting equipment and reducing the burden of exercise.

[0016] ② Equipped with emergency rescue capabilities: The light-emitting unit can realize the internationally recognized SOS rescue light mode through the control module, providing users with a standardized distress signal in case of sudden danger during outdoor sports, thereby improving the user's safety and chances of being rescued in emergency scenarios.

[0017] ③ Excellent heat dissipation and waterproof performance: By setting up heat dissipation components (such as heat dissipation film, heat dissipation aluminum plate) and heat conduction baffles, an efficient heat dissipation path of "LED bead → LED board → heat dissipation component → heat conduction baffle → outer wall of unit compartment" is constructed, which can reduce the working temperature of LED bead by 15-20℃ and ensure that its service life is maintained at more than 50,000 hours; at the same time, the unit compartment achieves IPX8 waterproof rating through the compartment cover and sealing structure (such as silicone sealing ring), and the assembly opening design takes into account the convenience of component installation and overall sealing, making it suitable for swimming, diving and other water-related scenarios.

[0018] ④ High wearing comfort and functional expandability: The flexible ear hook connector and back hook connector (silicone or silicone and nylon braided composite material) adapt to the contour of the human outer ear and the curve of the head, avoiding pressure during exercise; the auxiliary module can be used to separately install the battery and control module, solving the problem of insufficient unit compartment space, while supporting binaural stereo sound (left and right channel sound units), and can select single / dual unit compartment light-up configuration according to needs, taking into account both lighting effect and battery life (single light-up unit configuration can reduce power consumption by 15-20% and extend battery life by 1-2 hours).

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1 to 6 In this embodiment of the invention, a bone conduction headphone with lighting effects includes a headphone body 10, one end of which is fixedly fitted with a unit compartment 20 having an internal accommodating space. The unit compartment 20 is independently equipped with a sound-generating unit 40 and a light-emitting unit 30. The sound-generating unit 40 is used to generate sound wave vibrations to achieve bone conduction function; The side wall of the unit compartment 20 is provided with a light-emitting channel 23 extending radially therein. The light-emitting units 30 are sequentially assembled in the light-emitting channel 23 from the inside to the outside of the unit compartment 20. The light-emitting unit 30 includes a lamp board 31, a lamp bead 32 fixed to one side of the lamp board 31, and a lens 33. The lens 33 is sealed and assembled at the outer port of the light-emitting channel 23 extending outward, and the side of the lens 33 away from the light-emitting channel 23 forms an irradiation surface 25 that emits light outward. When the earphone body 10 is in the wearing state, the angle between the irradiation surface 25 and the horizontal plane is maintained at 45 to 89 degrees to ensure that the light passing through the lens 33 shines towards the ground.

[0025] Specifically, with the upgrading of residents' sports consumption demands, bone conduction headphones, due to their structural characteristics of not requiring air transmission and possessing IPX7 or higher waterproof performance, are widely used in sports scenarios such as swimming, diving, and night running. However, existing bone conduction headphones have significant functional defects: Lack of or ineffective lighting function: In night running scenarios, users need to see obstacles (such as stones and steps) 1-3 meters ahead. Existing headphones do not have a lighting function, requiring users to carry an extra flashlight, which increases the burden of exercise. In diving scenarios (such as shallow diving within 10 meters), the natural water area is dimly lit. Even if existing headphones have a built-in light, the light is directed vertically forward (with an angle close to 0 degrees to the horizontal plane), shining directly into the water in front of the user rather than onto the reefs / life below, which cannot meet the observation needs. Lack of emergency rescue function: When suddenly getting lost or injured during outdoor sports, the internationally recognized "SOS rescue signal (three short flashes → three long flashes → three short flashes, with a cycle of 10 seconds)" is a key means of calling for help. However, existing bone conduction headphones do not have this light mode and cannot provide users with emergency protection.

[0026] Based on the above requirements, this utility model integrates a sound-emitting unit 40 and a light-emitting unit 30 within the unit compartment 20. It uses the light-emitting channel 23 to guide the light in a directional manner and optimizes the illumination angle (45~89 degrees) to ensure that the light accurately covers the area 1-3 meters in front of the ground during night running and 0.5-2 meters below during diving. At the same time, the LED bead 32 in this solution can realize the SOS mode through the subsequent control module 15 (such as an MCU chip) to meet the needs of emergency rescue and fill the functional gap of existing products.

[0027] like Figures 1 to 3 As shown, preferably, when the earphone body 10 is in the wearing state, the angle between the irradiation surface 25 and the horizontal plane is maintained at 65~85 degrees, so as to further optimize the irradiation range of the light on the ground and make the light cover the ground area 2-3 meters in front of the user.

[0028] Specifically, to further adapt to the ground lighting needs of mainstream land sports scenarios such as night running and brisk walking, the angle between the illumination surface 25 and the horizontal plane is preferably limited to 65-85 degrees. Within this angle range, the light forms an incident angle of 10-25 degrees with the ground, which can cover a ground area of ​​2-3 meters in front of the user (compared to an angle of 45-64 degrees, the coverage area is increased by more than 30%), and the light will not shine directly into the eyes of pedestrians in front due to the excessive angle (close to 90 degrees), thus avoiding light pollution. At the same time, this angle corresponds to the illumination surface 25 forming a tilt state of 5-25 degrees with the vertical plane, which can be matched with the ear hook angle when the earphone body 10 is worn (usually at 15-20 degrees with the vertical plane), ensuring that the wearing comfort is not affected.

[0029] like Figures 1 to 3 As shown, preferably, when the earphone body 10 is in the wearing state, the angle between the irradiation surface 25 and the horizontal plane is maintained at 81 degrees, so as to precisely control the light irradiation area and ensure that the light covers the preset ground area in front of the user.

[0030] Specifically, through extensive user testing (sample size of 150 people, covering the mainstream population with head circumference of 54-62cm) and light simulation experiments, it was found that when the angle between the irradiated surface 25° and the horizontal plane is 81 degrees, a dual optimal effect can be achieved: Light coverage effect: The light forms a circular illumination area with a diameter of 1.5 meters on the ground (2 meters away from the user's feet), with an illumination intensity of over 50 lux, which can clearly identify pebbles with a diameter of 5mm or more on the ground, meeting the safety requirements for night running; Wearing fit: This angle corresponds to the illumination surface 25 forming a 9-degree tilt with the vertical plane, which perfectly matches the natural tilt angle (8-10 degrees) of the unit compartment 20 when most users wear headphones. Precise illumination can be achieved without adjusting the wearing position of the headphones, avoiding wearing discomfort caused by angle deviation.

[0031] Therefore, comparing the illumination effects at angles of 50 degrees, 65 degrees, 81 degrees, and 85 degrees: when the angle is 81 degrees, the light forms a uniform illumination area with a diameter of 1.5 meters (2 meters away from the user's feet) on the ground, with an illumination intensity of over 50 lux. It can clearly identify obstacles on the ground larger than 5mm (such as pebbles and steps), and the light will not shine directly into the eyes of pedestrians in front. Compared with other angles, this angle has the best overall performance in terms of illumination range, intensity, and safety. Therefore, the angle between the illumination surface 25 and the horizontal plane is determined to be 81 degrees, so that the light can accurately cover the core ground area required by the user during movement.

[0032] The 81-degree angle corresponds to the illumination surface 25 forming a 9-degree tilt with the vertical plane. When the earphone body 10 is worn, the natural tilt angle of the unit compartment 20 is usually 8-10 degrees (based on ergonomic data, it fits the outer ear contour of more than 95% of adults). The 81-degree angle is perfectly matched with this wearing angle, so that accurate illumination can be achieved without the user adjusting the position of the earphone, while avoiding the ear pressure caused by the angle deviation.

[0033] like Figure 3 and Figure 4 As shown, preferably, the light-emitting unit 30 further includes a heat dissipation component 34. The side of the lamp plate 31 away from the lamp bead 32 is the back side of the lamp plate 31. One side of the heat dissipation component 34 is tightly attached to the back side of the lamp plate 31, and the other side is tightly attached to the inner wall of the unit compartment 20, so as to transfer the heat generated by the lamp bead 32 to the unit compartment 20 in sequence through the lamp plate 31 and the heat dissipation component 34, and dissipate it to the outside through the outer wall of the unit compartment 20, thereby extending the service life of the lamp bead 32.

[0034] Specifically, the LED chip 32 generates continuous heat during operation (e.g., a 0.5W LED chip 32 can reach an operating temperature of 60-80℃). In this design, the LED chip 32 is assembled within the light-emitting channel 23, and the lens 33 is sealed to the outer port of the light-emitting channel 23 (to ensure waterproof performance). This results in a relatively enclosed space within the light-emitting channel 23, where heat easily accumulates. If heat is not dissipated in time, the lifespan of the LED chip 32 will be shortened from 50,000 hours to less than 20,000 hours. Therefore, a heat dissipation component 34 is assembled on the back of the lamp board 31 away from the LED chip 32. The heat dissipation component 34 can be any of the following: The graphite heat dissipation film (thickness 0.1-0.2mm, thermal conductivity 1500-2000W / (m·K)) is attached to the back of the lamp board 31 and the inner wall of the unit compartment 20 with thermally conductive adhesive, and is adapted to the complex curved surface of the unit compartment 20. A heat dissipation aluminum plate (thickness 0.5-1mm, thermal conductivity 200-230W / (m·K)) or a heat dissipation copper plate (thickness 0.3-0.8mm, thermal conductivity 380-400W / (m·K)) is fixed to the back of the lamp board 31 and the inner wall of the unit compartment 20 with screws. It is suitable for the planar area of ​​the unit compartment 20. The heat transfer path is: lamp bead 32 (60-80℃) → lamp board 31 (55-75℃) → heat dissipation component 34 (50-70℃) → outer wall of unit compartment 20 (45-65℃) → external environment. This can reduce the operating temperature of the lamp bead 32 by 15-20℃ and ensure that its lifespan is maintained at more than 50,000 hours.

[0035] like Figure 3 and Figure 4 As shown, preferably, the end of the light-emitting channel 23 facing the inside of the unit compartment 20 is provided with a heat-conducting baffle 24. The heat-conducting baffle 24 is either fixedly connected to the inner side wall of the unit compartment 20 or integrally formed with the inner side wall of the unit compartment 20. The heat dissipation component 34 is sandwiched between the back of the lamp plate 31 and the heat-conducting baffle 24, and the heat dissipation component 34 is closely attached to the back of the lamp plate 31 and the heat-conducting baffle 24 respectively, so as to enhance the efficiency of heat transfer from the heat dissipation component 34 to the unit compartment 20.

[0036] Specifically, to further improve the heat conduction efficiency of the heat dissipation component 34 to the outer wall of the unit compartment 20 (to prevent heat from spreading inside the unit compartment 20), a heat conduction baffle 24 is provided on the inner wall of the unit compartment 20 at the assembly position of the lamp board 31 and the lamp bead 32. Material and structure of heat conduction baffle 24: aluminum alloy (thermal conductivity 200-230W / (m·K)) or copper alloy (thermal conductivity 380-400W / (m·K)), thickness 1-2mm, area adapted to the back area of ​​lamp panel 31 (not less than 80% of the back area of ​​lamp panel 31) to ensure sufficient heat transfer area. The molding method of the heat-conducting baffle 24: Independent assembly: The prefabricated heat-conducting baffle 24 is fixed to the inner wall of the unit compartment 20 by screws or thermally conductive adhesive. This is suitable for scenarios where the unit compartment 20 is made of plastic material (such as ABS, PC), and can avoid the problem of poor thermal conductivity of plastic sidewalls (thermal conductivity 0.2-0.5W / (m·K)). Integrated molding: The heat-conducting baffle 24 and the unit compartment 20 (made of aluminum alloy) are integrally molded using a die-casting process, reducing assembly gaps and improving thermal conductivity by 15-20% compared to the independently assembled type; Assembly relationship: The heat dissipation component 34 is sandwiched between the back of the lamp panel 31 and the heat conduction baffle 24, and the gap between the three is filled by thermally conductive adhesive (thermal conductivity 1-3W / (m·K)), so that the heat transfer loss from the heat dissipation component 34 to the heat conduction baffle 24 is reduced to less than 5%, and finally the heat is quickly transferred to the outer wall of the unit compartment 20 through the heat conduction baffle 24 to achieve efficient heat dissipation.

[0037] like Figures 2 to 4 As shown, preferably, the unit compartment 20 is a hollow container with an internal accommodating space. One side of the unit compartment 20 is provided with an assembly opening 21 that communicates with the accommodating space. The assembly opening 21 is used for the insertion and assembly of the light-emitting unit 30 and the sound-emitting unit 40. The unit compartment 20 also includes a compartment cover 22, which is fixedly connected to the assembly opening 21. A sealing structure is provided between the compartment cover 22 and the assembly opening 21 to form a waterproof and sealed state.

[0038] Specifically, to simplify the assembly process of the light-emitting unit 30 and the sound-emitting unit 40 (reducing production difficulty), an assembly opening 21 is provided on one side of the unit compartment 20 with a receiving space. The size of the assembly opening 21 is not less than 80% of the maximum cross-section of the receiving space, ensuring that the light-emitting unit 30 (including the lens 33 and the lamp board 31) and the sound-emitting unit 40 (including the vibration module) can be installed as a whole into the receiving space without disassembling the parts, improving assembly efficiency by more than 40%. To ensure the waterproof performance of the unit compartment 20 (meeting the IPX8 waterproof requirements for swimming and diving scenarios), a compartment cover 22 is provided at the assembly opening 21. Fixing method: Ultrasonic welding (applicable to plastic compartment cover 22 and plastic unit compartment 20) or screw connection (applicable to metal compartment cover 22 and metal unit compartment 20) is used to ensure the connection strength between compartment cover 22 and unit compartment 20; Sealing structure: A silicone sealing ring (circular cross-section, 1-2mm in diameter) is set on the mating surface of the cover 22 and the assembly opening 21. The compression of the sealing ring is controlled at 30-50%, which can effectively prevent water from seeping into the containment space from the assembly opening 21. After testing, this sealing structure can be immersed in 1.5 meters of water for 30 minutes without water leakage.

[0039] like Figures 3 to 6 As shown, preferably, the earphone body 10 further includes an ear hook connector 11 and an auxiliary module 13; the ear hook connector 11 is a flexible structure, one end of which is fixedly connected to the outer wall of the unit compartment 20, and the other end is fixedly connected to the outer wall of the auxiliary module 13; the ear hook connector 11 has a cable channel extending along its length inside, and a cable is threaded through the cable channel. The two ends of the cable are electrically connected to the electrical components in the unit compartment 20 and the electrical components in the auxiliary module 13, respectively, so as to realize the signal and power transmission between the two.

[0040] Specifically, to improve wearing convenience and comfort, an ear hook connector 11 is fixedly connected to the outer wall of the unit compartment 20. The ear hook connector 11 is made of silicone or TPU material (Shore hardness 50-60HA) and has an arc-shaped structure (the arc is adapted to the contour of the human outer ear). Users can hang the ear hook connector 11 on the cartilage of the outer ear to achieve stable wearing of the headphone body 10. The flexible material can avoid pressure on the ears during exercise.

[0041] Since the unit compartment 20 needs to accommodate both the sound unit 40 (approximately 5-8 cm3) and the light-emitting unit 30 (approximately 3-5 cm3), the remaining space is less than 2 cm3, which is insufficient to accommodate the headphone's power battery (approximately 4-6 cm3) and control circuit board (approximately 2-3 cm3). Therefore, an auxiliary module 13 is provided at the end of the ear hook connector 11 away from the unit compartment 20. The auxiliary module 13 is a hollow shell (approximately 10-15 cm3), which is used to assemble a 3.7V lithium battery (capacity 500-800 mAh) and a control circuit board (integrating Bluetooth, light control, and other functions).

[0042] To achieve electrical connection between unit compartment 20 and auxiliary module 13, a cable channel with a diameter of 2-3mm is opened inside the ear hook connector 11. A 2-4 core cable (specification AWG30-AWG32) is run through the channel. One end of the cable is electrically connected to the light board 31 and the sound unit 40 in unit compartment 20 (to transmit power and control signals), and the other end is electrically connected to the control circuit board in auxiliary module 13. The cable channel is filled with waterproof glue to prevent water from seeping into the cable interface.

[0043] like Figures 3 to 6 As shown, preferably, the earphone body 10 further includes a rear hook connector 12, which is a flexible elongated structure; each end of the rear hook connector 12 is equipped with a set of components, each set of components including an auxiliary module 13, an ear hook connector 11 and a unit compartment 20, and the unit compartment 20 in the two sets of components is respectively equipped with a left channel sound unit 40 and a right channel sound unit 40 to realize the function of simultaneous playback of both ears.

[0044] Specifically, to achieve binaural stereo sound (enhancing music immersion), a rear hook connector 12 is added to the earphone body 10. The rear hook connector 12 is made of a silicone and nylon braided composite material (30-40cm in length, 1-1.5cm in width), which conforms to the contours of the back of the user's head, and the flexible material can adapt to the wearing needs of users with different head circumferences (54-62cm). Each end of the rear hook connector 12 is equipped with a set of "auxiliary module 13 + ear hook connector 11 + unit compartment 20" components. Configuration of sound unit 40: The left channel sound unit 40 (frequency response 20-20000Hz, sensitivity 95±3dB) and the right channel sound unit 40 (parameters are the same as the left channel) are respectively installed in the unit compartment 20 of the two components. The dual-channel synchronous playback is achieved through the signal cable inside the rear connector 12, and the delay is controlled within 50ms. Light-emitting unit 30 configuration: Two options are available to suit user needs: Dual-unit compartment 20 configuration: Both compartments 20 are equipped with light-emitting units 30. The angle between the illumination surface 25 of one compartment 20 and the horizontal plane is set to 65-70 degrees (illuminating the ground 1-2 meters in front), and the other is set to 80-85 degrees (illuminating the ground 2-3 meters in front). The total illumination surface area 25 can reach 4-6㎡, which is more than twice the size of a single light-emitting unit 30. The combined light intensity can reach 80-100 lux, which is suitable for night running scenarios in extremely dark conditions. Single-unit housing 20 configuration: Only the right ear housing 20 is equipped with a light-emitting unit 30 (most users are used to right-hand operation, which makes it easier to control the light), which can reduce power consumption by 15-20% and extend the earphone battery life from 6 hours to 7-8 hours, suitable for night running scenarios with low to medium light. Auxiliary module 13 configuration: Adopting a "functional split" design, the battery module 14 (3.7V 800mAh lithium battery) is installed on the left ear side of the auxiliary module 13, and the control module 15 is installed on the right ear side of the auxiliary module 13. The control module 15 includes: a Bluetooth 5.0 module (to enable wireless connection with a mobile phone), a sound control module 15 (to adjust the volume and switch songs), an LED bead 32 control module 15 (to switch between constant light / blinking / SOS mode), and a button module (including three push-buttons for power on / off, volume ±, and light mode). The button module adopts a waterproof design (a silicone waterproof pad is placed between the button and the housing of the auxiliary module 13) to ensure that the overall waterproof rating reaches IPX8; the control module 15 can use an STM32L4 series MCU chip (integrating the above functions, with a volume of only 1-2cm3), and is electrically connected to the battery module 14, the sound unit 40, and the light-emitting unit 30 through a cable to realize full-function control.
