Description

Technical Field

[0001] The present invention belongs to the technical field of hearing aids, and particularly relates to a hearing aid with wind noise suppression. Background Art

[0002] The development of hearing aids has been more than a hundred years. The current hearing aid technology has reached the design level of digitalization, miniaturization, and humanization. The most common hearing aids include cassette machines, behind-the-ear (BTE) machines, in-the-ear (ITE) machines, and canal (ITC) machines. BTE machines, ITE machines, and ITC machines are favored by people because of their small appearance. However, due to their small size, they are easy to fall off, and it is inconvenient to find them when they fall on the ground.

[0003] ITC machines need to be customized according to the wearer, so the cost is relatively high. BTE hearing aids have a wider adaptation range. Although their adaptability to the ear canal is lower, their price is lower than that of ITC machines, and they are used by the vast majority of people. According to market research feedback, ITC machine users wearing glasses often take off the ITC machines to relieve the discomfort caused by the pressure of the temple above the helix on the ITC machine.

[0004] Therefore, the existing ITC machines have poor comfort for users who need to wear glasses and cannot meet the requirements in actual use. So, there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a hearing aid with wind noise suppression. By providing a detachable support unit on the hearing aid main body, it can provide an effect of assisting in supporting the temple for users who need to wear glasses. By clamping the temple on the support unit, it can disperse the pressure at the highest point of the helix when wearing both a hearing aid and glasses at the same time, and it has the effect of preventing loss without wearing an anti-loss cord. The structure is simple, the installation is compact, and it has high practicability, solving the problem that the existing ITC machines have poor comfort for users who need to wear glasses.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Please refer to Figures 1-4As shown in the figure, the present invention is a hearing aid with wind noise suppression, including a hearing aid main body 1, an earplug part 2 and a anti-loss cord 4 installed on the hearing aid main body 1. In this application, the hearing aid main body 1 is an active noise reduction hearing aid, which generates a reverse sound wave equal to the external noise through a noise reduction system to neutralize the noise, so as to achieve the effect of noise reduction, reduce the wind noise and improve the wearing comfort. A through hole 8 is opened on the side wall of the hearing aid main body 1, and a mounting hole 11 is opened on the inner wall of the through hole 8. The anti-loss cord 4 is connected to the mounting hole 11. Installation balls 5 are fixedly sleeved at both ends of the anti-loss cord 4. The diameter of the installation ball 5 is larger than that of the mounting hole 11, and the installation ball 5 is made of silica gel material. The advantage of this setting is that the cost is low and it is convenient to manufacture. By pulling the anti-loss cord 4, the anti-loss cord 4 can be disassembled and assembled on the hearing aid main body 1 by pressing and pulling the anti-loss cord 4, so that the installation ball 5 deforms and engages with the mounting hole 11, and the installation and disassembly are convenient. The whole is light and has a low sense of presence. The anti-loss cord 4 is a prior art. A clip can be installed on the anti-loss cord 4 so that the anti-loss cord 4 can be clamped on the wearer's clothes. Compared with the existing method of connecting the anti-loss cord 4 and the hearing aid main body 1 through a push-button buckle, this application can effectively avoid the noise generated by the anti-loss cord being blown by the wind and colliding with the hearing aid main body 1 during cycling, and improve the wearing comfort. It also includes a support unit for supporting the temple. A horizontal section is integrally formed on the side wall of the hearing aid main body 1. The support unit includes a housing 3 installed at the horizontal section position. A pair of installation grooves 23 are opened on the horizontal section. A pair of installation keys 22 are fixedly installed at the positions corresponding to the installation grooves 23 on the bottom wall of the housing 3. The bottom end of the installation key 22 extends into the installation groove 23 and contacts the inner wall of the installation groove 23. An elastic band 6 is fixedly installed on the outer wall of the housing 3. The housing 3 is sleeved on the hearing aid main body 1 through the elastic band 6. The advantage of this setting is that it is convenient to disassemble and assemble the support unit, and it is suitable for users who need to wear glasses and those who do not need to wear glasses, making the hearing aid main body 1 lighter and improving the wearing comfort. The support unit also includes a clamping component for clamping the temple. The clamping component is connected to the housing 3. In this application, by setting a detachable support unit on the hearing aid main body 1, an effect of assisting in supporting the temple is provided for users who need to wear glasses. By clamping the temple on the support unit, the pressure at the highest point of the helix can be dispersed when wearing a hearing aid and glasses at the same time, improving the comfort of users wearing glasses. And without wearing the anti-loss cord 4, it also has the effect of preventing loss. The structure is simple and the installation is compact, with high practicality.

[0031] Among which, such as Figures 4-7As shown, the clamping assembly includes a pair of fixed blocks 13 fixedly installed on the inner wall of the bottom of the housing 3. A same fixed sleeve 18 is fixedly installed on the top of the fixed blocks 13. A first ear plate 9 and a second ear plate 12 are coaxially and rotatably installed on the fixed sleeve 18. Anti-slip pads 10 are fixedly sleeved on the ends of the first ear plate 9 and the second ear plate 12. The anti-slip pads 10 are made of silica gel. The advantage of such a setting is that when the first ear plate 9 and the second ear plate 12 clamp the temple, the anti-slip pads 10 can deform and fit with the temple, improving the clamping effect of the first ear plate 9 and the second ear plate 12, and the silica gel material can effectively enhance the friction force with the temple. The first ear plate 9 is of an H-shaped structure, and a U-shaped groove adapted to the second ear plate 12 is opened at the central position of the first ear plate 9. The advantage of such a setting is that the first ear plate 9 and the second ear plate 12 are staggered, suitable for temples of different specifications, and expanding the applicable range of the clamping unit. The first ear plate 9 and the second ear plate 12 are connected and assembled through an elastic member, and cooperate to form a clamp end that can be opened and closed under the action of the elastic member. The elastic member is a torsion spring, which is a prior art, so it will not be described in detail. Oppositely arranged guide blocks 21 are fixedly installed at the central positions of the first ear plate 9 and the second ear plate 12. A moving sleeve 17 is slidably sleeved in the fixed sleeve 18. Both ends of the moving sleeve 17 penetrate outside the fixed sleeve 18, and anti-drop rings 20 are fixedly installed. A pair of oppositely arranged guide holes 19 are integrally formed on the inner wall of the moving sleeve 17. A second bent rod 15 is fixedly installed in the upper guide hole 19. A push block 16 is fixedly installed at the end of the second bent rod 15. The end of the push block 16 extends to contact the pair of guide blocks 21. The end of the push block 16 is of a triangular structure. A first bent rod 14 is fixedly installed in the lower guide hole 19. A slider 7 is slidably installed on the side wall of the housing 3. One end of the first bent rod 14 extends to penetrate through the slider 7 and is fixedly connected to the slider 7. The slider 7 is of an arc-shaped structure, and a plurality of anti-slip grooves are equidistantly opened on the outer wall of the slider 7. The advantage of such a setting is that it can improve the friction force in contact with the skin. When the slider 7 is pushed to drive the whole moving sleeve 17 to slide in the fixed sleeve 18, the end of the push block 16 abuts against the pair of oppositely arranged guide blocks 21, so that the first ear plate 9 and the second ear plate 12 simultaneously squeeze the torsion spring and rotate relative to each other to separate. The temple is placed between the first ear plate 9 and the second ear plate 12. After the slider 7 is released, the torsion spring releases elastic potential energy, driving the first ear plate 9 and the second ear plate 12 to reset, clamping the temple above the housing 3 to support the temple, achieving the purpose of dispersing the pressure at the highest point of the helix when wearing a hearing aid and glasses simultaneously.

[0032] Working principle: First, select whether to install the clamping unit according to the user's needs. That is, users who do not wear glasses can achieve the anti-loss effect by installing the anti-loss rope 4 on the hearing aid main body 1. When the housing 3 needs to be installed, align the installation key 22 at the bottom of the housing 3 with the installation groove 23, and sleeve the housing 3 on the hearing aid main body 1 through the elastic band 6. When clamping the temple, by pushing the slider 7, the slider 7 and the first bent rod 14 drive the moving sleeve 17 to slide in the fixed sleeve 18. The moving sleeve 17 drives the push block 16 to abut against a pair of guide blocks 21. There is an opening at the top of the housing 3. The first ear plate 9 and the ear insertion part 2 rotate away from each other on the outer wall of the fixed sleeve 18. Place the temple between the first ear plate 9 and the second ear plate 12. After releasing the slider 7, the first ear plate 9 and the second ear plate 12 clamp the temple above the housing 3 to support the temple, so as to achieve the purpose of dispersing the pressure at the highest point of the helix when wearing a hearing aid and glasses simultaneously.

[0033] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
