Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a hearing aid. Background Technology

[0002] A hearing aid is a tool, device, or instrument that helps people with hearing impairments improve their hearing and thus enhance their ability to communicate with others. It amplifies weak sounds and transmits them into the patient's ear canal, allowing the patient to hear weaker sounds.

[0003] In existing technologies, hearing aids typically include a housing, an antenna assembly, a battery, a circuit board assembly, and a speaker assembly. These components are electrically connected as needed. The antenna assembly, battery, circuit board assembly, and speaker assembly are all housed within the housing, while the speaker assembly is mounted on the housing. To prevent the battery from shifting relative to the housing, it is restrained by an internal battery liner structure. This internal battery liner structure results in a relatively large overall size and weight for the hearing aid. Since hearing aids are worn on the ear for extended periods, there is a high demand for miniaturization and weight reduction. Therefore, there is room for improvement in the size and weight of existing hearing aid technologies.

[0004] Therefore, there is an urgent need for a hearing aid to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a hearing aid that solves the technical problems of large size and heavy weight in the prior art.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0013] In one embodiment, limiting structures are provided on both sides of the lining structure in the thickness direction; the main body includes a main body and two side plates, the extension structure is connected to the main body, the two side plates are connected to the main body, and the two side plates are disposed on both sides of the lining structure in the thickness direction and connected to the limiting structures on the corresponding side of the lining structure.

[0014] In one embodiment, the main board body is disposed on one side of the battery assembly in a first direction, the extension structure is provided with an output terminal, the output terminal is located on the other side of the battery assembly in the first direction, and the output terminal is used to electrically connect to the charging terminal of the hearing aid; the first direction, the width direction of the housing, and the thickness direction of the housing are mutually perpendicular.

[0015] In one embodiment, the extension structure extends circumferentially along the battery assembly; and / or, the liner structure has a first enclosure opposite to the battery assembly in a second direction and a second enclosure extending circumferentially along the battery assembly, the first enclosure and the second enclosure cooperating to form the semi-groove; the second direction is the thickness direction of the battery assembly.

[0016] In one embodiment, the hearing aid further includes an antenna assembly disposed on the inner liner structure; the hearing aid also includes an elastic structure through which the antenna assembly is electrically connected to the mainboard assembly.

[0017] In one embodiment, the antenna assembly has at least one extension extending toward the inner liner structure, and each extension is provided with at least one elastic structure between itself and the main board assembly.

Detailed Implementation

[0044] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0045] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0050] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0051] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] This embodiment provides a hearing aid that has a small size and light weight, meeting the requirements of miniaturization.

[0053] For example, such as Figures 1 to 18 As shown, the hearing aid includes a housing 100, an inner lining structure 200, a mainboard assembly 400, and a battery assembly 300. The housing 100 has an inner cavity 130. The inner lining structure 200, the mainboard assembly 400, and the battery assembly 300 are all located within the inner cavity 130. In this embodiment, the mainboard assembly 400, the inner lining structure 200, and the battery assembly 300 are all fixedly disposed within the inner cavity 130. The battery assembly 300 serves as the power supply for the entire hearing aid, powering the mainboard assembly 400 and other electronic components.

[0054] In this embodiment, the motherboard assembly 400 is disposed on the inner liner structure 200 so that it can be fixed by the inner liner structure 200. Furthermore, at least a portion of the motherboard assembly 400 cooperates with the inner liner structure 200 to form a limiting groove 430; that is, a portion of the limiting groove 430 is the motherboard assembly 400, and another portion is the inner liner structure 200. The battery assembly 300 is confined within the limiting groove 430; and the battery assembly 300 is electrically connected to the motherboard assembly 400.

[0055] It is understood that the inner lining structure 200 can serve as the main support structure inside the hearing aid. The components inside the hearing aid can be directly mounted on the inner lining structure 200 or between the inner lining structure 200 and the outer shell 100, so as to be limited by the inner lining structure 200 and the outer shell 100. This embodiment does not limit this.

[0056] In the hearing aid provided in this embodiment, a portion of the inner liner structure 200 and a portion of the main board assembly 400 cooperate to form a limiting groove 430 for limiting the battery assembly 300. This allows the main board assembly 400 to not only be used for electrical connection with other electrical components, but also for limiting the battery assembly 300, thus improving the utilization rate of the main board assembly 400. With the cooperation of the inner liner structure 200 and the main board assembly 400, the battery assembly 300 is limited together. Therefore, the size of the inner liner structure 200 can be set smaller than the size of the battery assembly 300, so that the overall size of the inner liner structure 200 and the main board assembly 400 can be smaller and the weight can be lighter, making the hearing aid more miniaturized and lightweight.

[0057] In some alternative embodiments, such as Figure 2As shown, the outer casing 100 may include a first housing 110 and a second housing 120 connected together. The first housing 110 and the second housing 120 are interconnected to form an inner cavity 130. By providing the connected first housing 110 and second housing 120, the assembly of the hearing aid can be facilitated, improving assembly efficiency. It should be noted that in this embodiment... Figure 2 The example shown is exemplified by the housing located at the bottom, which is the first housing 110, and the housing located at the top, which is the second housing 120. Of course, it can be understood that the housing located at the top can also be the first housing 110 and the housing located at the bottom can be the second housing 120. This embodiment does not limit this.

[0058] Optionally, such as Figure 8 As shown, the inner liner structure 200 is provided with a semi-groove 210. At least a portion of the battery assembly 300 is located in the semi-groove 210 so that it can be restrained by the inner liner structure 200.

[0059] For example, such as Figure 3 As shown, the motherboard assembly 400 includes a motherboard body 410 and an extension structure 420. The motherboard body 410 and the extension structure 420 are fixedly connected and electrically connected. In this embodiment, as... Figure 7 As shown, one end of the extension structure 420 is connected to the main board body 410, and the other end is bent towards the battery assembly 300, cooperating with the semi-groove 210 to form a limiting groove 430 for limiting the battery assembly 300. The shape of the limiting groove 430 matches the shape of the battery assembly 300 to restrict the movement of the battery assembly 300 relative to the extension structure 420 and the inner liner structure 200. Furthermore, the battery assembly 300 is also electrically connected to the main board assembly 400, thereby achieving the limiting of the battery assembly 300 within the outer casing 100. In this embodiment, the extension structure 420 and / or the main board assembly 400 are electrically connected to the battery assembly 300, enabling the battery assembly 300 to provide power to the extension structure 420 and / or the main board assembly 400.

[0060] It should be noted that if the inner liner structure 200 forms a groove for limiting the battery assembly 300 on its own, the size of the inner liner structure 200 needs to be set larger than the battery assembly 300 in order to achieve the purpose of limiting the battery assembly 300. In addition, the motherboard surrounds the outer periphery of the inner liner structure 200 to realize electrical connection with other electronic components. This results in the inner liner structure 200 and the motherboard being very large in size and weight.

[0061] The hearing aid provided in this embodiment has a portion of the inner liner structure 200 cooperating with a portion of the main board assembly 400 to form a limiting groove 430 for limiting the battery assembly 300. Specifically, the main board assembly 400 includes a main board body 410 and an extension structure 420. The extension structure 420 bends toward the battery assembly 300 and cooperates with the half-groove 210 of the inner liner structure 200 to form the limiting groove 430 for limiting the battery assembly 300. This allows the extension structure 420 to not only be used for electrical connection with other electrical components, but also for limiting the battery assembly 300, improving the utilization rate of the extension structure 420. The inner liner structure 200 does not need to separately limit the battery assembly 300. Therefore, the size of the inner liner structure 200 can be set smaller than the size of the battery assembly 300, so that the overall size of the inner liner structure 200 and the main board assembly 400 can be smaller and the weight can be lighter, making the hearing aid more miniaturized and lightweight.

[0062] Of course, hearing aids also include key hearing aid components such as microphone 700, receiver, and programming accessories. These are existing components of hearing aids, and their specific structures can be found in existing hearing aids, so they will not be described in detail here. These key hearing aid components can be placed inside the housing 100 as needed, or they can be placed outside the housing 100 in other ways, which will not be described in detail here.

[0063] The battery assembly 300 in this embodiment typically includes a rechargeable battery (not shown in the figure) and a battery circuit board (not shown in the figure) connected to the rechargeable battery. The rechargeable battery can be charged and discharged to enable recycling. The battery circuit board is electrically connected to the positive and negative terminals of the rechargeable battery and to the main board assembly 400, realizing the electrical connection between the rechargeable battery and the main board assembly 400. The shape of the rechargeable battery can be circular, square, etc., and this embodiment does not limit it.

[0064] In some optional embodiments, the hearing aid is further provided with a charging terminal 910, which is electrically connected to a rechargeable battery so that an external power source can charge the rechargeable battery through the charging terminal 910. The charging terminal 910 can be a charging port, a wireless charging structure, or a common charging structure in the prior art, and this embodiment does not limit it to any particular type.

[0065] For example, such as Figure 3 As shown, the extension structure 420 has an output terminal 421, which is used to electrically connect to the charging terminal 910, so that the charging terminal 910 is electrically connected to the rechargeable battery through the extension structure 420. Optionally, the output terminal 421 of the extension structure 420 can be a circuit board. With this configuration, the extension structure 420 is used not only to electrically connect to the charging terminal 910, but also as a limiting member to limit the position of the battery assembly 300.

[0066] To optimize the placement of the output terminal 421, battery assembly 300, and mainboard assembly 400, resulting in a smaller hearing aid that still meets requirements, in this embodiment, as follows... Figure 5 As shown, the main board body 410 is located on one side of the battery assembly 300 in the first direction X, and the output terminal 421 is located on the other side of the battery assembly 300 in the first direction X. The first direction X, the width direction of the housing 100, and the thickness direction of the housing 100 are mutually perpendicular. This arrangement ensures that the output terminal 421, the battery assembly 300, and the main board body 410 are sequentially arranged in a direction approximately equal to the length direction of the housing 100, preventing the hearing aid from being too thick or too wide, facilitating its use, and broadening its application range. In some optional embodiments, the first direction X can be the length direction of the housing 100.

[0067] Optionally, the charging terminal 910 is located at the end of the housing 100 in the first direction X, closer to the output terminal 421, so that the charging terminal 910 and the output terminal 421 are close to each other, facilitating electrical connection between the two. Figure 5 In the middle, the charging end 910 is located at the left end of the outer casing 100.

[0068] In some alternative embodiments, such as Figure 5 As shown, the extension structure 420 extends circumferentially along the battery assembly 300, that is, the extension structure 420 limits the battery assembly 300 in a direction perpendicular to the axis of the battery assembly 300. Since the extension structure 420 is essentially a circuit board, which can be a rigid circuit board or a flexible circuit board, in order to improve the limiting effect, the circuit board in this embodiment is a rigid circuit board. In this case, the extension structure 420 can be assembled from multiple circuit board segments to conform to the shape of the battery assembly 300. Since the limiting of the battery assembly 300 in the axial direction can be achieved by the outer casing 100, the extension structure 420 in this embodiment is mainly used to limit the battery assembly 300 in a direction perpendicular to the axis of the battery assembly 300. Of course, it can be understood that the extension structure 420 can also limit the battery assembly 300 in the axial direction of the battery assembly 300; this embodiment does not limit this.

[0069] Optionally, this embodiment provides an inner lining structure 200, such as... Figure 8 As shown, the inner liner structure 200 is provided with a first enclosure 220 opposite to the battery assembly 300 in the second direction Y and a second enclosure 230 extending circumferentially along the battery assembly 300. The first enclosure 220 and the second enclosure 230 cooperate to form a semi-groove 210; in this embodiment, the second direction Y is the thickness direction of the battery assembly 300.

[0070] By setting the first enclosure 220, the battery assembly 300 can be blocked in the second direction Y. It should be noted that the battery assembly 300 is provided with the first enclosure 220 on one or both sides in the second direction Y. This embodiment does not limit this. Figure 8 This is a schematic diagram showing that the battery assembly 300 has a first enclosure 220 on one side in the second direction Y. In this case, the battery assembly 300 can be limited on the other side in the second direction Y by the outer shell 100, making the inner liner structure 200 smaller and lighter. By setting a second enclosure 230, the second enclosure 230 can cooperate with the extension structure 420 to limit the battery assembly 300 and prevent the battery assembly 300 from moving.

[0071] In some alternative embodiments, please continue to refer to Figure 8 The inner lining structure 200 also includes a support plate 290. The first enclosure 220 and the second enclosure 230 are both connected to the support plate 290. Optionally, the second enclosure 230 can be composed of multiple blocks, which are spaced apart along the circumference of the battery assembly 300, so that the weight of the second enclosure 230 can be smaller while limiting the battery assembly 300.

[0072] There are various ways to configure the motherboard body 410; this embodiment provides one such configuration. Optionally, such as... Figure 8 As shown, the inner lining structure 200 is provided with a limiting structure 240, such as... Figure 7 As shown, the main board body 410 is disposed on the inner liner structure 200 and connected to the inner liner structure 200 via the limiting structure 240. By disposing the main board body 410 on the inner liner structure 200, the main board body 410 does not require a separate supporting component, reducing the number of components in the hearing aid and facilitating assembly. The limiting structure 240 connects the main board body 410 to the inner liner structure 200, reducing the size of the inner liner structure 200 and contributing to its miniaturization.

[0073] Further optionally, limiting structures 240 are provided on both sides of the lining structure 200 in the thickness direction. And, as... Figure 10As shown, the motherboard body 410 includes a main body 411 and two side plates 412, with the two side plates 412 located on the same side of the main body 411. An extension structure 420 is connected to the main body 411, meaning the extension structure 420 is electrically connected to the main body 411. Both side plates 412 are electrically connected to the main body 411, and are disposed on both sides of the inner lining structure 200 in the thickness direction, and are connected to a limiting structure 240 on the corresponding side of the inner lining structure 200. Specifically, the side plate 412 located on one side of the inner lining structure 200 is connected via the limiting structure 240 on that side, and the side plate 412 located on the other side of the inner lining structure 200 is connected via the limiting structure 240 on that other side, thus fixing the two side plates 412. Optionally, when the inner lining structure 200 includes a support plate 290, the limiting structure 240 is disposed on the support plate 290, and the support plate 290 is fixed in the space formed by the main body part 411 and the two side plate parts 412.

[0074] It should be noted that, in order to improve the space utilization inside the outer casing 100, the thickness directions of the outer casing 100, the battery assembly 300, the inner liner structure 200, and the main board body 410 are all consistent.

[0075] In one possible implementation, such as Figure 10 As shown, the side panel 412 is provided with a limiting fit structure 4121. The limiting fit structure 4121 cooperates with the limiting structure 240 to realize the connection between the main body 410 and the inner lining structure 200. For example, the limiting structure 240 can be snapped or interference-fitted with the limiting fit structure 4121. The setting of the limiting fit structure 4121 makes the connection structure with the side panel 412 simpler and facilitates the assembly of the side panel 412 and the inner lining structure 200.

[0076] The limiting structure 240 can have various structures, as long as it can achieve the limiting purpose. In one embodiment, such as... Figure 8 and Figure 9As shown, each side of the support plate 290 may include multiple limiting structures 240. Some of these limiting structures 240 may be limiting posts 241, some may be limiting hooks 242, some may be limiting blocks 243, etc. This embodiment does not limit these. When the limiting structure 240 is a limiting post 241, the limiting mating structure 4121 can be a limiting groove. The limiting post 241 engages with the limiting groove, thereby achieving the connection between the main board body 410 and the support structure 200. When the limiting structure 240 is a limiting hook 242, the limiting mating structure 4121 can be a limiting groove, a limiting plane, etc. The limiting hook 242 is hooked onto the limiting groove or the limiting plane to achieve the connection between the main board body 410 and the support structure 200. When the limiting structure 240 is a limiting block 243, the limiting mating structure 4121 can be a block provided on the side plate 412. The limiting is achieved through the abutment between the limiting block 243 and the block, thereby achieving the connection. There are various specific structures and limiting methods of the limiting structure 240, which will not be listed one by one in this embodiment.

[0077] To enrich the functionality of the hearing aid provided in this embodiment, such as... Figure 2 As shown, the hearing aid also includes an antenna assembly 500, which is disposed on the inner liner structure 200. In some alternative embodiments, the antenna assembly 500 is disposed on one side of the inner liner structure 200 in a third direction Z. The third direction Z intersects the thickness direction of the inner liner structure 200 and the length direction of the outer shell 100. Figure 5 In the indicated orientation, the antenna assembly 500 is located above the inner liner structure 200. The antenna assembly 500 is electrically connected to the main board assembly 400. In this embodiment, the antenna assembly 500 is electrically connected to the main board body 410. The antenna assembly 500 is used to receive and / or transmit signals to enable communication between the hearing aid and the outside world. It should be noted that the antenna assembly 500 being disposed on the inner liner structure 200 can be understood as the antenna assembly 500 being fixedly connected to the inner liner structure 200, detachably connected, etc., and this embodiment does not limit this.

[0078] There are various ways to electrically connect the antenna assembly 500 and the motherboard assembly 400. This embodiment provides a connection method between the antenna assembly 500 and the motherboard assembly 400.

[0079] For example, such as Figure 7 As shown, the hearing aid also includes an elastic structure 600, through which the antenna assembly 500 and the main board body 410 are electrically connected. Specifically, the elastic structure 600 abuts between the antenna assembly 500 and the main board assembly 400, and the antenna assembly 500 and the main board assembly 400 are electrically connected through the elastic structure 600.

[0080] In some optional embodiments, the elastic structure 600 in this embodiment is capable of elastic deformation and can elastically abut against the antenna assembly 500 and the motherboard assembly 400. This reduces the distance requirement between the antenna assembly 500 and the motherboard assembly 400, thereby reducing the assembly precision requirements and assembly difficulty of the antenna assembly 500 and the motherboard assembly 400, and improving the assembly efficiency of the hearing aid. Furthermore, since the elastic structure 600 is deformable, its elastic abutment position against the antenna assembly 500 or the motherboard assembly 400 can be a more flexible area, further reducing the requirements for the relative position of the antenna assembly 500 and the motherboard assembly 400.

[0081] In some alternative embodiments, such as Figure 12 and Figure 13 As shown, the antenna assembly 500 has at least one extension portion 510 extending toward the inner liner structure 200. Each extension portion 510 has at least one elastic structure 600 between it and the main board body 410. The elastic structure 600 abuts against the corresponding extension portion 510 and is electrically connected to it, thereby achieving electrical connection between each extension portion 510 and the main board assembly 400. By providing the extension portions 510, it is convenient for the antenna assembly 500 and the main board body 410 to be electrically connected via the elastic structure 600.

[0082] like Figure 6 As shown, two elastic structures 600 are provided, which abut against the two side plate portions 412 respectively, and against the opposing surfaces of the two side plate portions 412. As another example, two extension portions 510 are also provided, which are disposed opposite each other in the thickness direction of the main body 410. The two elastic structures 600 abut against the two extension portions 510 respectively, thereby realizing the electrical connection between the antenna assembly 500 and the main body 410. By providing two elastic structures 600, the electrical connection area and electrical connection strength between the antenna assembly 500 and the main body 410 are increased.

[0083] Further optional, such as Figure 8 or Figure 9 As shown, the inner lining structure 200 is provided with a positioning slot 250. For the corresponding details, please refer to [link / reference needed]. Figure 13A positioning block 520 is provided between the two extension portions 510. The positioning block 520 is positioned in the positioning slot 250. That is, the shape of the positioning slot 250 matches the shape of the positioning block 520, so that the positioning of the antenna assembly 500 by the inner liner structure 200 can be achieved through the mutually cooperating positioning slot 250 and positioning block 520, thereby limiting the relative position of the antenna assembly 500 and the inner liner structure 200. Since the position of the main board body 410 relative to the inner liner structure 200 is fixed, the relative position of the antenna assembly 500 and the main board body 410 can be limited by limiting the relative position of the antenna assembly 500 and the inner liner structure 200, which facilitates the electrical connection between the two.

[0084] In this embodiment, as Figure 6 As shown, the two extension portions 510 are in contact with the two side walls of the inner liner structure 200 in the thickness direction. Specifically, the two extension portions 510 are in contact with the two side walls of the support plate 290 in the thickness direction. With this arrangement, the two extension portions 510 and the support plate 290 are clamped together, thereby restricting the position of the antenna assembly 500 relative to the support plate 290 in the thickness direction, and achieving the limitation of the antenna assembly 500.

[0085] In this embodiment, the antenna assembly 500 is disposed on the inner liner structure 200. The inner liner structure 200 is also used to limit the battery assembly 300 and the motherboard assembly 400, so that the antenna assembly 500, the battery assembly 300 and the motherboard assembly 400 can all be fixed in the outer shell 100 through the inner liner structure 200. This improves the utilization rate of the inner liner structure 200, enriches the function of the inner liner structure 200, reduces the number of support structures that need to be set in the outer shell 100, and further improves the miniaturization and weight reduction of the hearing aid.

[0086] Optionally, the elastic structure 600 can have various forms; this embodiment provides one elastic structure 600, such as... Figure 14 As shown, the elastic structure 600 includes a spring body 610 and a bent portion 620 connected to one end of the spring body 610 and located on one side of the spring body 610. The spring body 610 abuts against one of the extension portion 510 of the antenna assembly 500 and the main board assembly 400. The bent portion 620 has an abutment arc surface 621, which abuts against the other of the main board assembly 400 and the extension portion 510. By providing the abutment arc surface 621, arc-shaped contact with the extension portion 510 of the antenna assembly 500 or the main board body 410 can be achieved, reducing the risk of damage to the antenna assembly 500 or the main board body 410 and providing higher reliability. In some optional embodiments, the abutment arc surface 621 can be formed by bending the bent portion 620. In other embodiments, the abutment arc surface 621 can also be formed by machining a spherical protrusion on the bent portion 620; this embodiment does not limit this.

[0087] To increase the force of the bent portion 620 against the antenna assembly 500 or the main board body 410, in this embodiment, please refer to... Figure 14 The spring body 610 has a groove 611 on the side facing the bending portion 620. A slider 622 abuts against the spring body 610 at the end of the bending portion 620 facing away from the spring body 610 (i.e., the end of the bending portion 620 not connected to the spring body 610). The slider 622 is slidably placed in the groove 611. When the distance between the antenna assembly 500 and the main board body 410 is different, the elastic structure 600 can slide in the groove 611 via the slider 622 to adjust the distance between the abutting arc surface 621 on the bending portion 620 and the spring body 610, thereby adjusting the height of the elastic structure 600 so that the bending portion 620 of the elastic structure 600 smoothly abuts against the antenna assembly 500 or the main board body 410. Therefore, the elastic structure 600 provided in this embodiment has a wide range of applications, stronger versatility, and a simpler structure.

[0088] To improve the waterproof performance of the hearing aid provided in this embodiment, in this embodiment, as follows: Figure 15 As shown, the first housing 110 has a stepped structure 111, and the second housing 120 has a boss 121 that mates with the stepped structure 111. The boss 121 can be inserted into the stepped structure 111, thus limiting the position between the first housing 110 and the second housing 120. Furthermore, the stepped structure 111 includes a stepped surface 1111 and a stepped side surface. The stepped side surface abuts against the side surface of the boss 121, thereby limiting the relative position of the first housing 110 and the second housing 120 in the wall thickness direction of the first housing 110. Figure 6 As shown, a sealing colloid 140 is provided between the step surface 1111 and the boss 121 of the step structure 111. The sealing colloid 140 is used to seal the gap between the top surface of the step surface 1111 and the boss 121, thereby achieving a seal at the connection position between the first housing 110 and the second housing 120 and improving the waterproof performance of the outer housing 100.

[0089] For example, the sealant 140 is usually a hot melt adhesive. When forming the sealant 140, it is necessary to first apply the adhesive to the top surface of the step surface 1111 or the boss 121, then assemble the first housing 110 and the second housing 120, and squeeze the adhesive tightly so that the adhesive fills the space between the top surface of the step surface 1111 and the boss 121. After standing for 7 or 8 hours, the adhesive cures, thus achieving the connection and sealing between the first housing 110 and the second housing 120.

[0090] To ensure sufficient adhesive between the step surface 1111 and the top surface of the boss 121, in this embodiment, as follows: Figure 16As shown, the boss 121 has a supporting protrusion 1211 on the surface facing the first housing 110 (i.e., the top surface of the boss 121). By providing the supporting protrusion 1211, the amount of adhesive can be controlled by using the supporting protrusion 1211 as a reference during the dispensing process. The adhesive can be controlled to completely cover the supporting protrusion 1211 to ensure the dispensing height, thereby ensuring the amount of adhesive between the first housing 110 and the second housing 120, thus ensuring the connection strength and sealing performance between the first housing 110 and the second housing 120.

[0091] Optionally, multiple support protrusions 1211 are provided, and the multiple support protrusions 1211 are evenly and spaced apart along the circumference of the second housing 120.

[0092] Because the sealing colloid 140 can only be obtained after standing for 7 or 8 hours after dispensing, the hearing aid cannot be moved to the next assembly station (or testing station) during the curing process, resulting in low production efficiency of the hearing aid.

[0093] To address the problem of low production efficiency, this embodiment improves production efficiency by modifying the first housing 110 and the second housing 120. Specifically, as... Figure 15 As shown, the inner wall of the first housing 110 is provided with a first welded body 112, and the inner wall of the second housing 120 is provided with a second welded body 122. The first welded body 112 and the second welded body 122 are welded by ultrasonic welding. With this configuration, after the first housing 110 and the second housing 120 are glued together, solder (e.g., solder paste) can be applied to the first welded body 112 and / or the second welded body 122. Then, the first housing 110 and the second housing 120 are snapped together. Subsequently, the first welded body 112 and the second welded body 122 are welded together by ultrasonic welding, thereby achieving pre-fixation of the first housing 110 and the second housing 120 through the welded first welded body 112 and the second welded body 122. The first housing 110 and the second housing 120 will not move relative to each other; therefore, the next process can proceed without waiting for the sealant to cure, thus improving the production efficiency of hearing aids.

[0094] In order to improve the strength of the pre-fixed first housing 110 and second housing 120, in this embodiment, multiple first welding bodies 112 and second welding bodies 122 are provided in a one-to-one correspondence, and each first welding body 112 and its corresponding second welding body 122 are welded by ultrasonic welding.

[0095] If the connection point between the first welded body 112 and the second welded body 122 is close to the bonding point between the first housing 110 and the second housing 120, ultrasonic welding may affect the properties of the sealing adhesive 140. In one possible embodiment, please refer to... Figure 6 and Figure 15The first welded body 112 extends into the second housing 120. This arrangement ensures that the welding points of the first welded body 112 and the second welded body 122 are far from the sealing colloid 140, preventing any impact on the properties of the sealing colloid 140 during ultrasonic welding. This guarantees the sealing effect of the sealing colloid 140 in sealing and connecting the first housing 110 and the second housing 120. It is understood that the second welded body 122 could also extend into the first housing 110; this embodiment does not limit this.

[0096] Exemplarily, the hearing aid also includes at least one microphone 700 disposed within the housing 100. The microphone 700 is used to generate sound and transmit it to the user's ear. The hearing aid may have one microphone 700, or it may have multiple microphones 700; this embodiment is not limited in this respect. Furthermore, as... Figure 15 As shown, each microphone 700 has at least one sound hole 150 on the housing 100, allowing sound to be transmitted. For example, the sound hole 150 is disposed on the second housing 120.

[0097] Optionally, such as Figure 7 As shown, the motherboard assembly 400 also includes a collection section 440 connected to the motherboard body 410, and at least one microphone 700 is electrically connected to the collection section 440. By setting the collection section 440, the multiple microphones 700 are combined, which facilitates the electrical connection between the microphones 700 and the motherboard body 410.

[0098] In some alternative embodiments, please continue to refer to Figure 7 The gathering section 440 includes a first connecting arm 441 and a second connecting arm 442 connected in sequence. The first connecting arm 441 is electrically connected to the main board body 410. Specifically, one end of the first connecting arm 441 is electrically connected to one of the two side plate sections 412. The other end of the first connecting arm 441 is electrically connected to the second connecting arm 442. The second connecting arm 442 is angled to the first connecting arm 441, such that the extending directions of the first connecting arm 441 and the second connecting arm 442 are consistent with the extending direction of the outer casing 100, thereby fully utilizing the internal space of the outer casing 100. Furthermore, the second connecting arm 442 has a gathering surface 4421, to which the microphone 700 is electrically connected. Optionally, a circuit board may be provided on the gathering surface 4421, and the microphone 700 can be connected to the circuit board on the gathering surface 4421 via a flexible circuit board, wires, etc., thereby achieving electrical connection.

[0099] Optionally, such as Figure 9 As shown, the inner lining structure 200 has a first support portion 260 and a first limiting portion 270, and the first support portion 260 and the second limiting portion are disposed on the support plate 290. Both the first support portion 260 and the second support portion are disposed towards the gathering portion 440. Specifically, as shown... Figure 11 As shown, the first connecting arm 441 is supported by the first support portion 260, thereby preventing the first connecting arm 441 from deforming and ensuring that the first connecting arm 441 does not move relative to the inner liner structure 200. The first limiting portion 270 is provided on the side of the second connecting arm 442 facing away from the gathering surface 4421, and forms a movable gap 280 between the second connecting arm 442 and the first limiting portion 270. This movable gap 280 is used to allow the second connecting arm 442 to move, so that when the microphone 700 is connected to the gathering portion 440, the gathering portion 440 can have a certain amount of room to move relative to the inner liner structure 200, in order to compensate for the positional deviation between the gathering portion 440 and the microphone 700 and the size deviation between the gathering portion 440 and the microphone 700, thereby reducing the assembly difficulty of the hearing aid.

[0100] In some alternative embodiments, such as Figure 2 As shown, the microphone 700 can be disposed on one side of the antenna assembly 500 in the thickness direction, and the component for electrically connecting the microphone 700 and the collection portion 440 can be disposed on the other side in the thickness direction of the antenna assembly 500. In this case, as... Figure 12 As shown, the antenna assembly 500 also has a through-hole 540, allowing the collection portion 440 and the microphone 700 to be electrically connected through the through-hole 540. It is understood that the microphone 700 can also be connected to the housing 100, or the microphone 700 can also be connected to the inner lining structure 200; this embodiment does not limit this.

[0101] Please continue reading Figure 12 One end of the antenna assembly 500 may also be provided with a snap-fit ​​slot 550, such as... Figure 18 As shown, the housing 100 is provided with a snap-fit ​​strip 180 that matches the snap-fit ​​groove 550. At least a portion of the snap-fit ​​strip 180 snaps into the snap-fit ​​groove 550, thereby limiting the antenna assembly 500 by the housing 100, so that the position of the antenna assembly 500 relative to the housing 100 is fixed.

[0102] Optionally, to facilitate control of the hearing aid's functions or switches, alternatively, such as Figure 1 As shown, the hearing aid also includes a button mechanism 800. Among them, as... Figure 15 As shown, the outer casing 100 is provided with a button through hole 160, which is used to install the button mechanism 800. Optionally, the button through hole 160 can be provided on the second casing 120.

[0103] To improve the waterproof performance of hearing aids, for example, such as Figure 6As shown, the button mechanism 800 includes a button assembly 810 and a waterproof structure 820. The button assembly 810 is movably disposed within the button through-hole 160, and the portion of the button assembly 810 located within the housing 100 can trigger a control switch 930 (e.g., a push switch) within the housing 100. The button assembly 810 triggering the control switch 930 can be achieved by the button assembly 810 touching the push switch. For example... Figure 17 and Figure 18 As shown, the waterproof structure 820 is fitted onto the button assembly 810. In some optional embodiments, the connection between the waterproof structure 820 and the button assembly 810 is sealed, that is, the waterproof structure 820 and the button assembly 810 are in close contact. The circumferential edge of the waterproof structure 820 is fitted to the outer shell 100. By providing the waterproof structure 820, both the waterproof structure 820 and the outer shell 100 and the waterproof structure 820 and the button assembly 810 are connected, thereby achieving separation between the interior of the outer shell 100 and the outside world. This prevents water and other substances from entering the outer shell 100 through the gap between the outer shell 100 and the button assembly 810, improving the waterproof performance of the hearing aid.

[0104] It should be noted that the waterproof structure 820 in this embodiment is capable of elastic deformation. Specifically, the waterproof structure 820 undergoes elastic deformation when the button assembly 810 moves relative to the outer casing 100. By providing the waterproof structure 820, when the button assembly 810 is pressed and moves relative to the outer casing 100, the waterproof structure 820 undergoes elastic deformation, preventing it from becoming immobile due to pulling, thus ensuring the functionality of the button assembly 810. Optionally, the waterproof structure 820 can be made of an elastic material, such as silicone or rubber; this embodiment does not limit this.

[0105] Optionally, this embodiment provides a button assembly 810, such as... Figure 17 and Figure 18 As shown, the button assembly 810 includes a button 811 and a button cap 812. At least a portion of the button 811 is located within the housing 100 and can trigger the control switch 930. At least a portion of the button cap 812 is slidably disposed in the button through hole 160 and connected to the button 811.

[0106] In one embodiment, such as Figure 18 As shown, the waterproof structure 820 is located within the outer casing 100, and the circumferential edge of the waterproof structure 820 is fitted and connected to the inner wall of the outer casing 100. Furthermore, the waterproof structure 820 is sleeved on the button 811 and is sealed to the button 811. In some optional embodiments, such as... Figure 17 As shown, the waterproof structure 820 has a waterproof hole 821, and part of the button 811 passes through the waterproof hole 821 and is connected to the hole wall of the waterproof hole 821.

[0107] In other embodiments, the waterproof structure 820 may also be located outside the housing 100, and the circumferential edge of the waterproof structure 820 may be attached to the outer wall of the housing 100. In this case, the waterproof structure 820 may be fitted onto the key cap 812, and may also achieve sealing of the key assembly 810.

[0108] In some optional embodiments, the connection between the button cap 812 and the button 811 can be welding. For example, the button cap 812 and the button 811 can be welded by ultrasonic welding. This embodiment does not limit this.

[0109] In one possible implementation, such as Figure 17 and Figure 18 As shown, button 811 includes a button body 8111 and a button protrusion 8112 connected to one side of the button body 8111. The button protrusion 8112 is connected to a button cap 812, and the end of the button protrusion 8112 facing away from the button body 8111 can extend into the button cap 812 and be connected to the button cap 812 by ultrasonic welding. A waterproof structure 820 is fitted onto the button protrusion 8112; that is, the button protrusion 8112 passes through a waterproof hole 821. Furthermore, the waterproof structure 820 is located between the button body 8111 and the button cap 812. By setting the button protrusion 8112, the connection between the button 811 and the button cap 812 is achieved, and the connection area between the button 811 and the waterproof structure 820 is small, making it easier to control the sealing effect between the two.

[0110] In some alternative embodiments, to facilitate the assembly of the waterproof structure 820, such as Figure 16 As shown, the inner wall of the outer casing 100 is provided with a shallow groove 170. In this embodiment, the shallow groove 170 is disposed on the second casing 120. Furthermore, at least a portion of the waterproof structure 820 is located in the shallow groove 170. By providing the shallow groove 170, the waterproof structure 820 can be positioned and installed without occupying excessive space inside the outer casing 100.

[0111] To improve the sealing effect between the waterproof structure 820 and the inner wall of the housing 100, in some optional embodiments, the antenna assembly 500 is positioned close to the button assembly 810, and, as... Figure 12 and Figure 18 As shown, the antenna assembly 500 is provided with a pressing structure 530, which abuts against the circumferential edge of the waterproof structure 820 and is used to press the waterproof structure 820 against the outer shell 100, thereby limiting the waterproof structure 820 so that the waterproof structure 820 can be tightly in contact with the inner wall of the outer shell 100 to further ensure the sealing and waterproof effect.

[0112] Optionally, to improve the uniformity of the external force applied to the waterproof structure 820, in this embodiment, the pressing structure 530 is annular to increase the contact area between the pressing structure 530 and the waterproof structure 820. In some optional embodiments, the annular pressing structure 530 can seal against the waterproof structure 820 to form a double-sealing structure, further improving the sealing effect of the hearing aid.

[0113] To reduce the risk of the waterproof structure 820 separating from the outer casing 100, optionally, such as Figure 17 As shown, the circumferential edge of the waterproof structure 820 is bonded to the inner wall of the outer casing 100 via an adhesive bonding agent 830. By providing the adhesive bonding agent 830, the connection strength between the waterproof structure 820 and the outer casing 100 can be improved, and the adhesive bonding agent 830 also provides a sealing effect. Exemplarily, the adhesive bonding agent 830 includes, but is not limited to, backing adhesive.

[0114] For example, the hearing aid may include a control switch 930, and, as Figure 17 As shown, the control switch 930 is located inside the housing 100; for example, the control switch 930 may be located on the antenna assembly 500. Movement of the button assembly 810 relative to the housing 100 can trigger the control switch 930. Optionally, as... Figure 12 As shown, the surface of the antenna assembly 500 facing the button through hole 160 may have a switch groove 560, the control switch 930 is placed in the switch groove 560, and the pressing structure 530 surrounds the outer periphery of the switch groove 560.

[0115] In some alternative embodiments, such as Figure 2 As shown, the hearing aid also includes a connector 920, which is used to connect cables, etc. In this embodiment, the connector 920 is electrically connected to the main board body 410.

[0116] The hearing aid provided in this embodiment has a relatively simple structure, which not only meets the requirements of miniaturization and lightweighting, but also meets the requirements of waterproofing. The connection between the main board body 410 and the antenna assembly 500 is quite ingenious.
