Description

Technical Field

[0001] This utility model relates to the field of hearing aids, and more particularly to a wearable bone conduction hearing aid device. Background Technology

[0002] Bone conduction hearing aids have been widely used in the field of hearing assistance because they can transmit sound directly through the skull to the inner ear without passing through the ear canal, thus bypassing the middle and outer ear barriers. They provide convenient hearing assistance solutions for people with hearing impairments.

[0003] However, existing bone conduction hearing aids still have many limitations in practical use and cannot meet the needs of hearing-impaired individuals in specific scenarios: On the one hand, for example, when attending a concert, due to the limited power design of the sound unit, existing bone conduction devices cannot provide wearers with sufficient sound wave vibration intensity in scenarios that require a strong sense of impact, such as live concerts, making it difficult for hearing-impaired people to fully experience the infectiousness of the atmosphere; on the other hand, traditional cochlear implants are easily affected by environmental noise in noisy environments, resulting in unstable hearing aid effects, which further affects hearing-impaired people's ability to capture sound information at the scene.

[0004] On the other hand, the human body's sensitivity to sound and tolerance to vibration vary depending on the location. Experiments have shown that the sternum and clavicle are ideal locations that are both sensitive to sound and can withstand strong vibrations, making them the optimal placement positions for bone conduction sound units. However, existing bone conduction devices generally lack precise fixation structures for these specific locations and do not take into account the body shape differences of different users, making them difficult to adjust.

[0005] Based on this, we propose a wearable bone conduction hearing aid. Utility Model Content

[0006] To address the technical problems of existing bone conduction devices generally lacking precise fixation structures for these specific locations and failing to consider the differences in body shape among different users, making them difficult to adjust, this utility model provides a wearable bone conduction hearing aid device.

[0007] This utility model is achieved by the following technical solution: a wearable bone conduction hearing aid device, characterized in that it includes a hearing aid vest, the surface of the hearing aid vest is provided with an opening for taking out and putting in objects, a zipper is connected to the opening of the hearing aid vest, a storage pocket is sewn on the surface of the hearing aid vest, a main board is provided inside the hearing aid vest extending to the surface, and a side wearing adjustment mechanism is fixedly connected to both sides of the hearing aid vest body. The sliding module includes a lower buckle, which is hinged to the upper buckle via a pivot. A retaining plate is fitted onto the surface of the pivot shaft. The upper strap passes through the gap between the lower and upper buckles and is secured by the retaining plate. A clavicle vibration module is attached to the bottom of the upper strap. A chest vibration module is attached to the back of the hearing aid vest at the chest area. The main board is electrically connected to the clavicle vibration module and the chest vibration module via electrical wires.

[0008] As a further optimization of this utility model, the hearing aid vest is fixedly connected to both sides of the body with a side wearing adjustment mechanism, which is used to fix and adjust the tightness of the device on the side of the body.

[0009] As a further optimization of this utility model, the side wearing adjustment mechanism includes a side fixing part, which has a U-shaped structure and is fixed to the surface of the hearing aid vest by sewing. A side female buckle is connected to the outside of the side fixing part, and a side female buckle is snapped onto the outside of the side female buckle. A groove is opened at the end of the side female buckle, and a locking sleeve is inserted into the groove. A wearing strap is fixed to one side of the locking sleeve by sewing. The wearing strap is made of spandex blend material, which is elastic and can adapt to the wearing needs of users of different body types.

[0010] As a further optimization of this utility model, two sets of side-mounted adjustment mechanisms are provided. The two sets of mechanisms are respectively connected to both sides of the hearing aid vest and are connected by wearing straps. In use, the wearing straps wrap around the user's body, using their elasticity to achieve basic tightness adjustment, ensuring that the hearing aid vest fits the body and avoids shaking.

[0011] As a further optimization of this utility model, the upper surface of the hearing aid vest is also connected to a top wearing adjustment mechanism, which is used to assist in fixing the device from the top and further improve the wearing stability.

[0012] As a further optimization of this utility model, the top surface wearing adjustment mechanism includes a top surface fixing part, which is fixed to the surface of the hearing aid vest by sewing; a top surface female buckle is connected to the outside of the top surface fixing part, and a top surface female buckle is snapped onto the outside of the top surface female buckle. The end of the top surface female buckle is provided with a plug hole, and the top surface female buckle and the top surface female buckle are locked together by plugging, thereby realizing the connection between the top surface adjustment structure and the backpack.

[0013] As a further optimization of this utility model, one end of the adjusting belt passes through the connector hole and extends outward. The extended belt body passes through the adjusting buckle, and a limit rod is fixedly installed on the inner side of the adjusting buckle. There are two sets of limit rods, which are cylindrical and are fixed inside the adjusting buckle in a parallel manner. The adjusting belt passes through the two sets of limit rods in an alternating manner and locks in place through friction. The user can adjust its length by pulling the adjusting belt to achieve precise tension control.

[0014] As a further optimization of this utility model, one end of the adjustment strap is integrally and fixedly connected to an upper strap, the bottom end of which is connected to the wearing strap, and the two are fixed together by a fastener. The upper strap is worn on the user's shoulder and collarbone, and works with the side wearing adjustment mechanism to form a top pull, further improving the wearing stability of the device.

[0015] As a further optimization of this utility model, the side female buckle, side male buckle, top female buckle, and top male buckle are all made of ABS plastic. The inner side of the side male buckle and the top male buckle are provided with elastic claws, and the outer side of the side female buckle and the top female buckle are provided with slots that match the corresponding elastic claws. When the side female buckle and the side male buckle, and the top female buckle and the top male buckle are fastened together, the elastic claws are engaged in the corresponding slots. When the female buckle and the male buckle are fastened together, the elastic claws are engaged in the slots, ensuring the firmness of each connection and preventing them from falling off during use.

[0016] As a further optimization of this utility model, the modular sliding component includes a lower buckle and an upper buckle, which are hinged by a pivot. The locking plate is sleeved on the pivot and fixes the upper strap. When it is necessary to adjust the position of the modular sliding component on the upper strap, the locking between the lower buckle and the upper buckle is opened, and the locking plate loses its fixation to the upper strap. The user can pull the position of the modular sliding component on the upper strap. The position of the clavicle vibration module pasted at the bottom of the modular sliding component on the upper strap is also adjusted synchronously and randomly, accurately aligning with the sensitive area of ​​the clavicle and ensuring efficient vibration transmission.

[0017] As a further optimization of this utility model, the hearing aid vest achieves integrated storage and protection of bone conduction hearing aids. The side and top wearing adjustment mechanisms work together to achieve multi-directional fixation and tightness adjustment, which not only solves the problem of inconvenience in carrying and fixing existing devices, but also adapts to different user body shapes, ensures stable contact between the device and the body, guarantees the efficiency of bone conduction sound wave transmission, and improves the user experience.

[0018] As a further optimization of this utility model, two sets of upper straps are provided, and clavicle vibration modules are installed on the surface of the two sets of upper straps. A chest vibration module is installed on the back of the hearing aid vest, which fits against the chest. Vibrations are transmitted to the human body through the sternum and clavicle, two optimal locations that are "sound-sensitive and resistant to strong vibrations": the chest vibration module at the sternum fits against the chest, and the vibration is transmitted directly to the thoracic skeleton via the sternum; the clavicle vibration module at the clavicle is precisely aligned with the clavicle via the shoulder strap slider, and the vibration is transmitted to the skull via the clavicle. Both paths bypass the outer and middle ear barriers, directly transmitting sound wave vibrations to the auditory nerve of the inner ear to achieve sound perception, while keeping both ears open and also taking into account the perception of ambient sound.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves multi-directional fixation and fine-tuning through the coordinated action of the side and top wearing adjustment mechanisms. The U-shaped fixing part on the side, together with the elastic wearing strap, can wrap around the body to form a basic fixation; the top adjustment strap allows for fine-tuning of its length via adjusting buckles and limiting rods, and the connection between the upper strap and the wearing strap creates top tension. This structure adapts to different body shapes, ensuring the device fits the body snugly and preventing shifting or shaking during daily activities, thus solving the problem of unstable fixation in existing devices.

[0020] 2. By prying open the locking between the lower and upper buckles, the card plate loses its fixation to the upper strap. The user can pull the position of the module sliding component on the upper strap, and the position of the clavicle vibration module attached to the bottom of the module sliding component on the upper strap will also be adjusted synchronously and randomly, accurately aligning with the sensitive area of ​​the clavicle and ensuring efficient vibration transmission.

[0021] 3. This utility model device specifically installs the clavicle vibration module on the upper strap and the chest vibration module against the chest, precisely targeting the sternum and clavicle, two optimal locations that are sensitive to sound and resistant to strong vibrations. Vibrations are transmitted through the sternum to the thoracic skeleton or through the clavicle to the skull, bypassing the outer and middle ear obstructions and directly acting on the inner ear auditory nerve. At the same time, it keeps both ears open to allow ambient sound to be heard, significantly improving bone conduction efficiency and hearing aid effect.

[0022] 4. The connecting components of this utility model adopt a snap-fit ​​structure made of ABS plastic. The elastic claws on the inner side of the female snap-fit ​​precisely match the slots on the outer side of the female snap-fit, ensuring a secure connection and preventing it from falling off during use. Meanwhile, the stretchable nature of the wearing straps and upper straps adapts to users of different body types, ensuring a secure fit while reducing body pressure and discomfort caused by friction between the device and the body, significantly improving the user experience.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example 1: Please combine Figures 1-8 This embodiment proposes a wearable bone conduction hearing aid device, including a hearing aid vest 1. The surface of the hearing aid vest 1 is provided with an opening for taking and placing objects. A zipper 2 is connected to the opening of the hearing aid vest 1. A main board 3 is provided inside the hearing aid vest 1 extending to the surface.

[0027] The hearing aid vest 1 has side wearing adjustment mechanisms 4 fixedly connected to both sides of the body; wherein, the side wearing adjustment mechanism 4 includes a side fixing part 41, which is sewn onto the surface of the hearing aid vest 1. The side fixing part 41 has a U-shaped structure. A side female buckle 42 is connected to the outside of the side fixing part 41.

One side of the locking sleeve 44 is sewn and fixed to a wearing strap 45.

[0028] Specifically, the side-mounted adjustment mechanisms 4 on both sides of the device are connected to the hearing aid vest 1 via side-mounted fixing parts 41. After the side female buckle 42 and side female buckle 43 are locked together, the wearing straps 45 can be connected to the backpack body via locking sleeves 44. The two sets of side-mounted adjustment mechanisms 4 wrap around the user's body via the wearing straps 45. Utilizing the elasticity of the spandex blend material of the wearing straps 45, basic tightness adjustment is achieved to ensure that the hearing aid vest 1 fits the body and avoids shaking.

[0029] Furthermore, two sets of side-wearing adjustment mechanisms 4 are provided, and the two sets of side-wearing adjustment mechanisms 4 are connected to both sides of the hearing aid vest 1, and the two sets of side-wearing adjustment mechanisms 4 are connected by wearing straps 45.

[0030] The upper surface of the hearing aid vest 1 is connected to a top surface wearing adjustment mechanism 5, which includes a top surface fixing part 51, and the top surface fixing part 51 is sewn onto the surface of the hearing aid vest 1. A top surface female buckle 52 is connected to the outside of the top surface fixing part 51. A top surface male buckle 53 is snapped onto the outside of the top surface female buckle 52. A plug hole 54 is opened at the end of the top surface male buckle 53. The top surface female buckle 52 and the top surface male buckle 53 are plugged and locked together.

[0031] One end of the adjusting belt 55 passes through the connector hole 54 and extends outward. The belt body extending outward from the adjusting belt 55 passes through the adjusting buckle 56. A limit rod 57 is fixedly installed on the inner side of the adjusting buckle 56.

[0032] In the specific technical solution, the top surface wearing adjustment mechanism 5 of the hearing aid vest 1 is fixed by the top surface fixing part 51. After the top surface female buckle 52 and the top surface female buckle 53 are inserted and locked, the adjustment strap 55 passes through the insertion hole 54 and extends to the adjustment buckle 56. The user can pull the adjustment strap 55 to make it alternately rub and lock between the two sets of limiting rods 57 inside the adjustment buckle 56, so as to achieve precise control of the length of the adjustment strap 55.

[0033] Two sets of limiting rods 57 are provided. The limiting rods 57 are cylindrical. The two sets of limiting rods 57 are fixedly installed inside the adjusting buckle 56 in a parallel manner. The adjusting belt 55 passes through the two sets of limiting rods 57 in an alternating manner for friction locking.

[0034] One end of the adjustment strap 55 is integrally and fixedly connected to an upper strap 58. The bottom end of the upper strap 58 is connected to the wearing strap 45, and the upper strap 58 and the wearing strap 45 are fixed together by a fixing buckle 59. The upper strap 58 at one end of the adjustment strap 55 is connected to the wearing strap 45 by the fixing buckle 59, forming a top tension. The upper strap 58 is carried on the user's shoulder, further improving the wearing stability of the device.

[0035] The module sliding component 6 includes a lower buckle 61, which is rotatably hinged to the upper buckle 62 via a rotating shaft 63. A retaining plate 64 is sleeved on the shaft surface of the rotating shaft 63. The upper strap 58 passes through the gap between the lower buckle 61 and the upper buckle 62 and is fixed by the retaining plate 64. The clavicle vibration module 7 is attached to the bottom of the upper strap 58, and the chest vibration module 8 is attached to the back of the hearing aid vest 1 at the chest position. The main board 3 is electrically connected to the clavicle vibration module 7 and the chest vibration module 8 through electrical wires.

[0036] The specific technical solution involves a sliding module 6 comprising a lower buckle 61 and an upper buckle 62, hinged together by a pivot 63. A locking plate 64 is fitted onto the pivot 63 and fixes the upper strap 58. When the position of the sliding module 6 on the upper strap 58 needs to be adjusted, the locking between the lower buckle 61 and the upper buckle 62 is released, and the locking plate 64 loses its fixation to the upper strap 58. The user can then pull the sliding module 6 to adjust its position on the upper strap 58. Simultaneously, the position of the clavicle vibration module 7 attached to the bottom of the sliding module 6 on the upper strap 58 is also adjusted accordingly, precisely aligning with the sensitive area of ​​the clavicle to ensure efficient vibration transmission.

[0037] In the specific technical solution, the motherboard 3 uses the ESP32S3 chip. The motherboard 3 preprocesses the received audio signal, including amplification and noise reduction. It receives the audio signal sent by the host through the onboard antenna and preprocesses it. Then, it is connected to the sound unit through the audio amplifier MAX98357.

[0038] More specifically, the processed audio signal drives the clavicle vibration module 7 and the clavicle vibration module 7 fixed at the position of the sternum and clavicle. (The vibration motor of the clavicle vibration module 7 and the clavicle vibration module 7 is a taptic motor (LRA linear resonant actuator)) to convert the electrical signal into mechanical vibration, ensuring that the sound wave energy is efficiently transmitted to the bone.

[0039] Vibrations are transmitted to the body through the sternum and clavicle, two optimal sites that are "sensitive to sound and resistant to strong vibrations": The chest vibration module 8 at the sternum fits against the chest, and the vibration is transmitted directly to the thoracic skeleton through the sternum. The clavicle vibration module 7 at the clavicle is precisely aligned with the clavicle via a shoulder strap slider, and the vibration is transmitted to the skull through the clavicle.

[0040] Both pathways bypass the outer and middle ear barriers, directly transmitting sound wave vibrations to the auditory nerve in the inner ear to achieve sound perception, while keeping both ears open to accommodate environmental sound perception.

[0041] It should be noted that the side female buckle 42, side male buckle 43, top female buckle 52, and top male buckle 53 are all made of ABS plastic. The inner side of the side male buckle 43 and the top male buckle 53 are provided with elastic claws, and the outer side of the side female buckle 42 and the top female buckle 52 are provided with slots that match the corresponding elastic claws. When the side female buckle 42 and the side male buckle 43, and the top female buckle 52 and the top male buckle 53 are fastened together, the elastic claws are engaged in the corresponding slots.

[0042] More specifically, the ABS plastic side female buckle 42, side female buckle 43, top female buckle 52, and top female buckle 53 are engaged with the slots by elastic claws to ensure the firmness of each connection part; while the stretchable wearing strap 45 and the top strap 58 can adapt to users of different body types, ensuring a fixed effect while reducing the pressure on the body, ensuring that the bone conduction hearing aid maintains stable contact with the body during use, and ensuring sound wave transmission efficiency.

[0043] The working principle of this utility model: This wearable bone conduction hearing aid is based on the core logic of bone conduction technology. It provides hearing assistance through a complete chain of "audio signal reception - processing - vibration conversion - bone conduction". At the same time, it combines an adjustment mechanism to ensure adaptability and stability in strong vibration scenarios. The specific working principle is as follows: I. Fixing and adjusting the side of the garment: The side-mounted adjustment mechanisms 4 on both sides of the device are connected to the hearing aid vest 1 via the side fixing part 41. After the side female buckle 42 and the side female buckle 43 are locked together, the wearing strap 45 can be connected to the backpack body via the locking sleeve 44. The two sets of side-mounted adjustment mechanisms 4 wrap around the user's body via the wearing strap 45. Utilizing the elasticity of the spandex blend material of the wearing strap 45, basic tightness adjustment is achieved to ensure that the hearing aid vest 1 fits the body and avoids shaking.

[0044] II. Auxiliary fixation and adjustment of the top surface: The top surface adjustment mechanism 5 of the hearing aid vest 1 is fixed by the top surface fixing part 51. After the top surface female buckle 52 and the top surface female buckle 53 are inserted and locked, the adjustment strap 55 passes through the insertion hole 54 and extends to the adjustment buckle 56. The user can pull the adjustment strap 55 to make it alternately rub and lock between the two sets of limiting rods 57 inside the adjustment buckle 56, so as to achieve precise control of the length of the adjustment strap 55. The upper strap 58 at one end of the adjustment strap 55 is connected to the wearing strap 45 through the fixing buckle 59 to form a top tension. The upper strap 58 is worn on the user's shoulder and collarbone, which further improves the wearing stability of the device.

[0045] The ABS plastic side female buckle 42, side female buckle 43, top female buckle 52, and top female buckle 53 are engaged with the slots by elastic claws to ensure the firmness of each connection part; while the stretchable wearing strap 45 and the top strap 58 can adapt to users of different body types, ensuring a fixed effect while reducing the pressure on the body, ensuring that the bone conduction hearing aid maintains stable contact with the body during use, and ensuring sound wave transmission efficiency.

[0046] III. Positioning Logic of the Module Sliding Component The modular sliding component 6 includes a lower buckle 61 and an upper buckle 62, which are hinged by a pivot 63. The locking plate 64 is sleeved on the pivot 63 and fixes the upper strap 58. When it is necessary to adjust the position of the modular sliding component 6 on the upper strap 58, the locking between the lower buckle 61 and the upper buckle 62 is opened, and the locking plate 64 loses its fixation to the upper strap 58. The user can then pull the position of the modular sliding component 6 on the upper strap 58. The position of the clavicle vibration module 7 attached to the bottom of the modular sliding component 6 on the upper strap 58 is also adjusted synchronously and randomly, accurately aligning with the sensitive area of ​​the clavicle and ensuring efficient vibration transmission.

[0047] IV. Audio Signal Reception and Processing The motherboard 3 uses the ESP32S3 chip. The motherboard 3 preprocesses the received audio signal, including amplification and noise reduction. It receives the audio signal from the host through the onboard antenna and preprocesses it. Then, it is connected to the sound unit through the audio amplifier MAX98357.

[0048] V. Vibration Conversion and Bone Conduction Energy conversion of the vibrating unit The processed audio signal drives the clavicle vibration module 7 and the clavicle vibration module 7 fixed at the sternum and clavicle positions (the vibration motor of the clavicle vibration module 7 and the clavicle vibration module 7 is a taptic motor (LRA linear resonant actuator)) to convert the electrical signal into mechanical vibration, ensuring that the sound wave energy is efficiently transmitted to the bone.

[0049] Bone conduction pathway: Vibrations are transmitted to the body through the sternum and clavicle, two optimal sites that are "sensitive to sound and resistant to strong vibrations": The chest vibration module 8 at the sternum fits against the chest, and the vibration is transmitted directly to the thoracic skeleton through the sternum. The clavicle vibration module 7 at the clavicle is precisely aligned with the clavicle via a shoulder strap slider, and the vibration is transmitted to the skull through the clavicle.

[0050] Both pathways bypass the outer and middle ear barriers, directly transmitting sound wave vibrations to the auditory nerve in the inner ear to achieve sound perception, while keeping both ears open to accommodate environmental sound perception.
