Description

Technical Field

[0001] This invention relates to the field of hearing aids, and more particularly to a bone conduction hearing aid with adjustable wearing pressure. Background Technology

[0002] Humans perceive sound through two main pathways: one is through air conduction, where sound waves vibrate the eardrum through the external auditory canal and are then transmitted to the inner ear via the ossicles; the other is through bone conduction, where sound waves are transmitted directly to the inner ear through skeletal structures such as the skull and jawbone. Bone conduction devices are based on the second pathway. They use a vibrator placed in an appropriate position on the head to convert audio signals into mechanical vibrations. These vibrations are transmitted directly through the bones to the cochlea in the inner ear, allowing the user to perceive sound.

[0003] In the prior art, such as the utility model patent with Chinese patent number 202323611060.0, an adjustable gain bone conduction hearing aid is disclosed. By attaching multiple adjustment grooves and an elastic adjustment cord to the back of the bone conduction hearing aid, the problem of not being able to adjust the tightness and gain effect in the prior art is solved. This allows for adjustment of the gain effect to meet the needs of users with different head sizes, providing a better user experience and sound transmission. However, the use of the elastic adjustment cord can easily cause obstruction during the user's wearing process. Therefore, there is an urgent need for a bone conduction hearing aid with a more reasonable structure to overcome the shortcomings of the prior art. Summary of the Invention

[0004] To address the technical problem that existing bone conduction hearing aids cannot simultaneously possess both portability and pressure adjustment functions, this invention provides a solution.

[0005] To achieve the above objectives, the present invention provides a bone conduction hearing aid with adjustable wearing pressure, comprising:

[0006] An elastic frame, wherein both ends of the elastic frame are bent in the same direction to form a back hook that surrounds the user's head, and both ends are also provided with ear hooks for wearing on the user's ears; the back hook is designed to generate wearing pressure on the two ear hooks.

[0007] A first microphone and a second microphone are communicatively connected and both are provided with a connecting structure. Both connecting structures are provided with at least two abutment notches with different flexibility coefficients. The ear loop has an abutment end that can be selectively connected to the abutment notch to generate different pressures.

[0008] As an improvement of this application, the first microphone and the second microphone are connected by a wire. The wire follows the contour of the elastic frame and its two ends pass through the connecting structure at the same end to connect to the microphone at the same end.

[0009] As an improvement of this application, the connecting structure consists of a first structure and a second structure, wherein the first structure is fixedly connected to be inserted into the microphone; and the two snap-fit ​​notches are provided on two adjacent cylindrical surfaces of the second structure.

[0010] As an improvement of this application, the concave surface of any of the snap-fit ​​notches is provided with a flexible portion, and the buffering coefficients of the two flexible portions are different.

[0011] As an improvement of this application, the second structure includes a first cylindrical surface and a second cylindrical surface with the flexible portion, and the first cylindrical surfaces of the two second structures are arranged opposite to each other; the buffering coefficient of the flexible portion located on the first cylindrical surface is less than the buffering coefficient located on the second cylindrical surface.

[0012] As an improvement to this application, it also includes a first sleeve, which is sleeved on the lug and the corresponding wire and extends to the surface of the second structure; the end of the first sleeve facing the second structure is flared outward to form an operating space for switching the abutment notch at the abutment end.

[0013] As an improvement to this application, it also includes a second sleeve portion, which is sleeved on the neck portion and the corresponding wire, and extends to one end of the first sleeve portion at both ends.

[0014] As an improvement of this application, both the first microphone and the second microphone include a battery unit, a bone conduction unit, and a drive board; the drive boards corresponding to the first microphone and the second microphone are communicatively connected.

[0015] As an improvement to this application, a charging port is further formed on the outer wall surface of the first microphone and / or the second microphone, and the charging port is electrically connected to the corresponding battery cell on the same side.

[0016] The beneficial effects of this invention are as follows: Compared with the prior art, this invention provides a bone conduction hearing aid with adjustable wearing pressure, comprising an elastic frame, a first microphone, and a second microphone. The two ends of the elastic frame are bent in the same direction to form a back hook that surrounds the user's head, and both ends are also provided with ear hooks for wearing on the user's ears. The back hook allows the two ear hooks to generate wearing pressure. The first microphone and the second microphone are communicatively connected and both have a connecting structure. Each connecting structure has at least two abutment notches with different flexibility coefficients. The ear hooks have abutment ends that can be selectively connected to the abutment notches to generate different pressures. By providing at least two abutment notches with different flexibility coefficients on the connecting structure, and by using abutment ends that can selectively engage with these notches at the ends of the ear hooks, the wearing pressure can be adjusted according to the user's specific head size, sensitivity to clamping force, and fatigue from prolonged wear. Furthermore, since the back hook does not employ an additional restraint structure, the user's wearing experience is improved. Attached Figure Description

[0026] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0027] In the following description, specific examples are given to provide a more in-depth understanding of the invention. It is obvious that the described embodiments are merely some, not all, of the embodiments of the invention. It should be understood that the specific embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0029] To address the aforementioned technical problems, this application provides a bone conduction hearing aid with adjustable wearing pressure. Please refer to the appendix. Figure 1 To be continued Figure 5 The device includes an elastic frame 1, a first microphone 2, and a second microphone 3. The elastic frame 1 has two ends bent in the same direction to form a backrest 11 that encloses the user's head, and both ends are also provided with ear hooks 12 for wearing on the user's ears. The backrest 11 allows the two ear hooks 12 to generate wearing pressure. The first microphone 2 and the second microphone 3 are communicatively connected and both have a connecting structure 4. Each connecting structure 4 has at least two abutment notches 41 with different flexibility coefficients. The ear hooks 12 have abutment ends 13 that can be selectively connected to the abutment notches 41 to generate different pressures. By providing at least two abutment notches 41 with different flexibility coefficients on the connecting structure 4, and by using abutment ends 13 that can be selectively inserted into these notches at the ends of the ear hooks 12, the wearing pressure can be adjusted according to the different flexibility coefficients. Users can choose the most suitable setting based on their head size, sensitivity to clamping force, and fatigue from prolonged wear. Furthermore, the backrest 11 does not employ an additional constraint structure, resulting in a better wearing experience for the user.

[0030] In this embodiment, the first microphone 2 and the second microphone 3 are connected by a wire 5. The wire 5 follows the contour of the elastic frame 1, and both ends are connected to the microphones at the same end by the connecting structure 4. It is easy to understand that by connecting the first microphone 2 and the second microphone 3 by the wire 5 that follows the contour of the elastic frame 1, stable communication between the first microphone 2 and the second microphone 3 is achieved, and the functional performance is more stable.

[0031] As an important embodiment of this application, the connecting structure 4 is composed of a first structure 42 and a second structure 43. The first structure 42 is fixedly connected by being inserted into the microphone. Two snap-fit ​​notches are provided on two adjacent cylindrical surfaces of the second structure 43. It is easy to understand that by specifically defining the connecting structure 4 as the first structure 42 that is inserted and fixed and the second structure 43 that bears the abutment notch 41, the technical effect of decoupling functional modules, facilitating division of labor in manufacturing and rapid assembly is achieved in terms of modular design and production assembly. The first structure 42 is responsible for a firm connection with the physical body formed by the microphone, while the second structure 43 is specifically responsible for pressure adjustment. This division of labor improves production efficiency and ease of maintenance. In a further embodiment, each snap-fit ​​notch has a flexible part 44 on its concave surface, and the two flexible parts 44 have different buffering coefficients. The flexible parts 44 can be fixed to the snap-fit ​​notch by means of silicone, polymer sheets, adhesives, physical riveting, etc. Due to the different buffering coefficients, the wearing pressure formed by the subsequent elastic frame will vary from light to heavy. Thus, three, four, or more snap-fit ​​notches can be set, and flexible parts 44 with different buffering coefficients can be arranged on the corresponding snap-fit ​​notches to achieve more levels of pressure adjustment.

[0032] As a specific embodiment, while continuing the aforementioned implementation scheme, the second structure 43 includes a first cylindrical surface and a second cylindrical surface with a flexible portion 44, and the first cylindrical surfaces of the two second structures 43 are arranged opposite to each other; the buffering coefficient of the flexible portion 44 located on the first cylindrical surface is less than that located on the second cylindrical surface; when the user snaps the abutting end 13 onto the first cylindrical surface, the deformation at both ends of the elastic skeleton 1 is small, and the overall wearing pressure is small; when the user adjusts the abutting end 13 to the second cylindrical surface, the relative distance between the two abutting ends 13 is the largest, so the pressure that can be presented is the largest, and since the buffering coefficient of the second cylindrical surface is small, the pressure that can be formed is also larger, which can specifically obtain a larger wearing pressure and can effectively meet the needs of customers with different wearing pressures; it is worth further explaining that the undulating portion formed on both sides of the snapping notch restricts the abutting end 13 within the recessed structure formed by the buffer portion, so that the user can maintain the required wearing pressure well.

[0033] In this embodiment, a first sleeve is also included. The first sleeve is fitted onto the ear loop 12 and the corresponding wire 5 and extends to the surface of the second structure 43. The end of the first sleeve facing the second structure 43 is flared outward to form an operating space for switching the contact end 13 to the contact notch 41. By adding a first sleeve with a flared opening at one end, and the first sleeve being made of a flexible material, the user can adjust the position of the contact end 13 by swinging their fingers, so that the contact end 13 can choose to engage with the notch to generate wearing pressure. The pull-out design can fit the space required by the trajectory formed by the contact end 13 during adjustment.

[0034] In this embodiment, a second sleeve portion 7 is also included. The second sleeve portion 7 is fitted onto the neckband and the corresponding wire 5, and its two ends extend to one end of the first sleeve portion 6. It is easy to understand that by adding the second sleeve portion 7, which covers the entire length of the back hanging portion 11, a comprehensive soft wrapping effect is achieved in terms of overall protection and tactile optimization of the area in contact between the device and the user's neck skin is achieved. It not only protects the internal frame and wire 5, but its soft material properties also directly improve the tactile comfort of the skin on the back of the neck when wearing it. In actual use, it can avoid the discomfort of hard materials in cold weather or the friction of hard materials on the skin during exercise.

[0035] In this embodiment, both the first microphone 2 and the second microphone 3 include a battery unit, a bone conduction unit, and a driver board. The driver boards corresponding to the first microphone 2 and the second microphone 3 are communicatively connected. By clearly defining that each microphone integrates core functional modules such as a battery, bone conduction unit, and driver board, and that the driver boards are interconnected, the basic technical function of forming an independent, complete, and collaborative binaural audio processing system is achieved in terms of device functional integrity. In a further embodiment, a charging port is formed on the outer surface of the first microphone 2 and / or the second microphone 3. The charging port is electrically connected to the corresponding battery unit on the same side. By integrating the charging port on the outer wall of the microphone, the technical effect of providing a standardized and easily accessible charging interface and simplifying the battery life management process is achieved in terms of the convenience of device energy maintenance.

[0036] The advantages of this invention are:

[0037] By setting at least two abutment notches with different flexibility coefficients on the connecting structure, and with the abutment end of the ear hook that can be selectively inserted into these notches, the different flexibility coefficients can be used to change the wearing pressure on the user. The user can choose the most suitable level according to their specific head size, sensitivity to clamping force, and fatigue from wearing for a long time. Furthermore, since the back hook does not use an additional restraint structure, the user's wearing experience is better.

[0038] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
