Description

Technical Field

[0001] This utility model relates to the field of headphone products, and specifically to a bone conduction headphone. Background Technology

[0002] Bone conduction technology converts audio signals into mechanical vibrations that act directly on the temporal or zygomatic bone, transmitting sound to the cochlea and bypassing the outer and middle ear. This method is particularly suitable for users with blocked ear canals or middle ear dysfunction.

[0003] Chinese utility model patent CN218352681U discloses a solar-powered rechargeable bone conduction headphone, which includes two headphone bodies and ear hooks connected to the headphone bodies. The ear hooks are curved to fit the human head. However, in actual use, it has been found that when the headphone bodies do not fit snugly against the human head, there is a problem of sound leakage from the vibrator, affecting the user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of sound leakage caused by the vibrator in the prior art, this utility model provides a bone conduction headphone. The bone conduction headphone includes: a headband structure with a curved shape to fit the human head; the bone conduction structure includes housings installed at both ends of the headband structure and a vibrator installed within the housings; the housings include a main body fixedly connected to the headband structure and a cover plate connected to the main body; a damping plate is arranged within the housings, and the damping plate is close to the cover plate; an environmental sensor for monitoring air quality and temperature / humidity is suspended on the outside of the housings.

[0006] This utility model of bone conduction headphones includes a headband structure and a bone conduction structure. The headband structure is perfectly shaped to fit the human head, allowing for a snug fit and reducing sound leakage caused by a misfit. The bone conduction structure includes housings mounted at both ends of the headband structure and a vibrator mounted within each housing. Each housing includes a main body and a cover plate for mounting the vibrator. A damping plate is installed within the housing, near the cover plate, to absorb the vibration of the vibrator, suppress unnecessary resonance, and reduce the transmission of vibration to the housing, further reducing sound leakage. An environmental sensor monitors the user's environment in real time, enhancing the functionality of the bone conduction headphones and improving the user experience. Through the above-described design, this utility model of bone conduction headphones incorporates a damping plate to absorb the vibration of the vibrator, suppress unnecessary resonance, and reduce the transmission of vibration to the housing, thus minimizing sound leakage.

[0007] Furthermore, a module housing is provided on the outside of the environmental sensor, and the module housing is fitted to the box body.

[0008] Furthermore, a waterproof layer is provided inside the box, close to the cover plate. This arrangement of the waterproof layer prevents water droplets from seeping into the box.

[0009] Furthermore, a limiting block is provided inside the housing, and the limiting block is arranged circumferentially along the oscillator. Through this arrangement, the limiting block can position and clamp the oscillator.

[0010] Furthermore, the headband structure is made of ABS (acrylonitrile-styrene-butadiene copolymer) or PC (polycarbonate). Through this design, the materials possess good resilience, enhancing internal shear stress and allowing the headband to fit snugly against the human face.

[0011] Furthermore, the damping sheet is made of microporous polyurethane foam, silicone foam, or EVA foam (ethylene-vinyl acetate copolymer).

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] (1) The headband structure is designed to fit the human head perfectly, which can fit the human head and reduce sound leakage caused by the bone conduction structure not fitting the human head.

[0014] (2) A damping plate is installed inside the enclosure. The damping plate is close to the cover plate and can absorb the vibration of the oscillator, suppress unnecessary resonance, and reduce the transmission of vibration to the enclosure, thereby further reducing sound leakage.

[0015] (3) Set up an environmental sensor. The environmental sensor can monitor the parameters of the user's environment in real time, increase the function of bone conduction headphones, and improve the user experience. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] To improve or solve the technical problem of sound leakage caused by the vibrator in the prior art, this utility model provides a bone conduction headphone. The bone conduction headphone includes: a headband structure 1, which has a curved shape to fit the human head; a bone conduction structure 2, including a housing 21 installed at both ends of the headband structure 1, and a vibrator 22 installed in the housing 21; the housing 21 includes a main body 211 fixedly connected to the headband structure 1, and a cover plate 212 connected to the main body 211; a damping plate 26 is arranged inside the housing 21, and the damping plate 26 is close to the cover plate 212; an environmental sensor 3 for monitoring air quality and temperature and humidity is suspended on the outside of the housing 21.

[0024] Figure 1 This is a schematic diagram of an embodiment of the bone conduction headphones of this utility model. Figure 1 As shown, in one or more embodiments, the bone conduction headphones of this utility model include a headband structure 1, a bone conduction structure 2, and an environmental monitoring structure 3.

[0025] Figure 2 This is an exploded structural diagram of an embodiment of the bone conduction headphones of this utility model. Figure 1 and Figure 2 As shown, the headgear structure 1 has a curved shape that conforms to the human head. Based on Figure 1As shown, the left half of the headband structure 1 extends upward and backward from the left end, then curves upward and forward to the right. The right half of the headband structure 1 is mirror-symmetrical to the left half. Furthermore, the headband structure 1 can be integrally injection molded, meaning the entire headband structure 1 is a single piece. Alternatively, the left and right halves of the headband structure 1 can be injection molded separately and then connected by connectors. For example, the length of the headband structure 1 can be adjusted by a tension strip structure, thereby adjusting the clamping force of the headband structure 1. The tension strip structure is a commonly used headphone tension strip structure, which will not be described in detail here. Furthermore, the material of the headband structure 1 is ABS (acrylonitrile-styrene-butadiene copolymer) or PC (polycarbonate). These materials have good resilience, which can enhance internal shear stress, thereby allowing the bone conduction structure 2 to fit snugly against the human face.

[0026] See also Figure 1 and Figure 2In one or more embodiments, two bone conduction structures 2 are provided, with each bone conduction structure 2 respectively arranged at both ends of the head-mounted structure 1, and the two bone conduction structures 2 are connected for communication via wires. Alternatively, the two bone conduction structures 2 can also communicate via a suitable communication module such as a Bluetooth module. Each bone conduction structure 2 includes a housing 21 installed at both ends of the head-mounted structure 1, and a vibrator 22 installed inside the housing 21. The housing 21 includes a main body 211 fixedly connected to the head-mounted structure 1, and a cover plate 212 connected to the main body 211. Specifically, the main body 211 can be fixedly connected to the head-mounted structure 1 by a suitable method such as snap-fit ​​or adhesive, and the cover plate 212 can be fixedly connected to the main body 211 by a suitable method such as snap-fit ​​or adhesive. Further, a volume up / down button 23 and a start button 24 are provided on one of the housings 21. Specifically, the volume up / down button 23 is arranged on the cover plate 212, and the start button 24 is arranged on the main body 211. Volume up / down buttons 23 and start button 24 are both connected to the vibrator 22. It is understood that multiple components (not shown in the figure) are arranged on the vibrator 22, and the volume up / down buttons 23 and start button 24 are connected to these components. Furthermore, limit blocks 25 are provided on the main body 211, arranged circumferentially around the vibrator 22 to position and limit its movement. Specifically, the limit blocks 25 are approximately angle iron-shaped, and four are provided. Further, a damping sheet 26 is provided inside the housing 21, arranged on the cover plate 212 and matching its shape. Specifically, the damping sheet 26 has through holes that correspond to the volume up / down buttons 23. Further, the damping sheet 26 is made of microporous polyurethane foam, silicone foam, or EVA foam (ethylene-vinyl acetate copolymer). All of the above materials can absorb vibration energy and have low density and light weight, thus avoiding increasing the overall weight of the headphones. Furthermore, a waterproof layer 27 is provided inside the housing 21. The waterproof layer 27 is disposed between the damping sheet 26 and the cover plate 212. For example, the waterproof layer 27 can be a waterproof and breathable membrane, which is attached to the damping sheet 26, and also has through holes on the waterproof layer 27 that correspond to the volume up / down buttons 23.

The environmental monitoring module includes a module housing 31 that fits into the housing 21, and an environmental sensor 32 disposed within the module housing 31. Specifically, the module housing 31 is generally streamlined and fits into the rear sidewall of the main body 211. Further, the environmental sensor 32 is connected to a PCB board, which is mounted inside the module housing 31, and the environmental sensor 32 is mounted on the PCB board. Specifically, a positioning block is provided inside the module housing 31 to position and limit the environmental sensor 32 and the PCB board. Further, through holes are provided on the module housing 31 and the main body 211, and the PCB board and the vibrator 22 are connected via terminals to achieve linkage between the environmental sensor 32 and the vibrator 22.
