Description

Technical Field

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

[0002] With the rapid development of hearing aid technology, wireless charging has become an important feature of modern hearing aids. The design of the charging case typically requires the hearing aid unit to fit precisely into the charging slot to ensure proper contact of the charging contacts. However, some hearing aids (especially behind-the-ear hearing aids) are equipped with larger ear tips (such as large-sized earplugs or earmolds) to improve wearing comfort and acoustic performance.

[0003] While these oversized ear tips improve sealing and wearing stability, their larger size can cause the overall size of the hearing aid unit to exceed the standard capacity of the charging case, making it difficult for users to place the hearing aid smoothly into the charging case and even affecting the reliability of the charging contacts. Furthermore, forcibly squeezing the ear tips may cause them to deform or accelerate aging, affecting the acoustic performance and wearing comfort of the hearing aid.

[0004] Most current charging case designs do not adequately consider the compatibility of over-ear hearing aids, resulting in a poor charging experience for users. Therefore, there is an urgent need for a new charging case structure or hearing aid fixing solution to accommodate over-ear hearing aids, ensuring convenient charging and device reliability.

[0030] Example 1:

[0031] Please see the appendix Figure 1-4 To address the aforementioned problems, this utility model provides a hearing aid assembly, including a hearing aid main unit 10 and a charging case 20. The hearing aid main unit 10 includes a housing 11, a first circuit module, and an ear cap. The housing 11 is provided with a sound guide 111; the first circuit module is disposed inside the housing 11 and is used to acquire and amplify ambient sound sources; the ear cap is mounted on the sound guide 111, and the outer diameter of the ear cap is larger than the outer diameter of the housing 11. The charging case 20 includes a base 21, a second circuit module, and a cover 22. The upper end of the base 21 is provided with a first cavity 211, the second circuit module is disposed inside the base 21, and the lower end of the cover 22 is provided with a second cavity 221. The cover 22 can be closed onto the upper end of the base 21, so that the first cavity 211 and the second cavity 221 are connected; the inner diameter of the second cavity 221 is greater than or equal to the outer diameter of the ear cap. When the hearing aid main unit 10 is disposed within the first cavity 211, the ear cap is accommodated within the second cavity 221.

[0032] The technical features of this utility model include a hearing aid main unit 10 with a housing 11, a first circuit module, and an ear cap; and a charging case 20 with a base 21, a second circuit module, and a cover 22. The first circuit module inside the housing 11 is used to acquire and amplify ambient sound sources. The ear cap is mounted on the sound guide 111, and the outer diameter of the ear cap is larger than the outer diameter of the housing 11. This design allows the hearing aid main unit 10 to better acquire and transmit sound, and makes wearing the hearing aid more comfortable. The base 21 and cover 22 of the charging case 20 are respectively provided with a first cavity 211 and a second cavity 221. The cover 22 can close to the base 21, connecting the two cavities. The inner diameter of the second cavity 221 is greater than or equal to the outer diameter of the ear cap, ensuring that the ear cap can be smoothly accommodated within the second cavity 221, thus solving the problem of accommodating large-ear cap hearing aids within the charging case 20. Through this structural design, the hearing aid main unit 10 can be accurately placed into the charging case 20, ensuring correct connection of the charging contacts, preventing ear cap deformation or aging, and improving the user's charging experience.

[0033] The hearing aid main unit 10 includes a housing 11, a first circuit module, and an ear cap. A sound guide 111 is provided on the housing 11, and the first circuit module is disposed inside the housing 11 for acquiring and amplifying ambient sound sources. The ear cap is mounted on the sound guide 111, and the outer diameter of the ear cap is larger than the outer diameter of the housing 11. The charging case 20 includes a base 21, a second circuit module, and a cover 22. A first cavity 211 is provided at the upper end of the base 21, and the second circuit module is disposed inside the base 21. A second cavity 221 is provided at the lower end of the cover 22, and the cover 22 can close onto the upper end of the base 21, allowing communication between the first cavity 211 and the second cavity 221. The inner diameter of the second cavity 221 is greater than or equal to the outer diameter of the ear cap. When the hearing aid main unit 10 is disposed within the first cavity 211, the ear cap is accommodated within the second cavity 221.

[0034] A first circuit module is installed inside the housing 11 of the hearing aid main unit 10 to acquire and amplify ambient sound sources. The ear cap is mounted on the sound guide 111, and its outer diameter is larger than the outer diameter of the housing 11. The base 21 and cover 22 of the charging case 20 are respectively provided with a first cavity 211 and a second cavity 221. The cover 22 can close to the base 21, connecting the two cavities. The inner diameter of the second cavity 221 is greater than or equal to the outer diameter of the ear cap, ensuring that the ear cap can be smoothly accommodated within the second cavity 221, thus solving the problem of accommodating oversized hearing aids within the charging case 20. This structural design ensures that the hearing aid main unit 10 can be accurately placed into the charging case 20, ensures correct connection of the charging contacts, avoids ear cap deformation or aging, and improves the user's charging experience.

[0035] For example, the housing 11 of the hearing aid unit 10 can be made of a durable and lightweight material, while the ear tips can be made of a soft and elastic material to ensure wearing comfort and a good seal. The base 21 and cover 22 of the charging case 20 can be made of a sturdy and non-slip material to ensure stability and reliability during use. Furthermore, the second circuit module inside the charging case 20 can be designed with intelligent recognition capabilities, automatically detecting the placement status of the hearing aid unit 10 and performing the corresponding charging operation. With this design, users can easily charge the hearing aid unit 10 simply by placing it inside the charging case 20.

[0036] Compared with existing technologies, the hearing aid assembly of this invention solves the problem of accommodating over-ear hearing aids within the charging case 20 by incorporating two cavities within the charging case 20. Existing charging case 20 designs typically do not adequately consider the compatibility of over-ear hearing aids, potentially leading to issues such as ear tip deformation and aging during charging, affecting the reliability of charging contacts and the acoustic performance of the hearing aid. The design of this invention, through its optimized cavity structure, ensures that the hearing aid unit 10 can be accurately placed into the charging case 20, guaranteeing proper charging contact alignment and improving the user's charging experience.

[0037] By adopting the above technical solution, this utility model solves the compatibility problem between the hearing aid main unit 10 and the charging case 20, especially the problem of accommodating the over-ear hearing aid in the charging case 20 and the docking of the charging contacts. A first circuit module is installed inside the shell 11 of the hearing aid main unit 10 to acquire and amplify ambient sound sources. The earpiece is mounted on the sound guide 111, and the outer diameter of the earpiece is larger than the outer diameter of the shell 11. The base 21 and cover 22 of the charging case 20 are respectively provided with a first cavity 211 and a second cavity 221. The cover 22 can close to the base 21, connecting the two cavities. The inner diameter of the second cavity 221 is greater than or equal to the outer diameter of the earpiece, ensuring that the earpiece can be smoothly accommodated in the second cavity 221, thus solving the problem of accommodating the over-ear hearing aid in the charging case 20. Through this structural design, the hearing aid main unit 10 can be accurately placed into the charging case 20, ensuring correct docking of the charging contacts, preventing earpiece deformation or aging, and improving the user's charging experience.

[0038] Example 2:

[0039] Based on Embodiment 1, this embodiment further defines the hearing aid components provided in Embodiment 1. See also Figure 1-3In this embodiment, the diameter of the housing 11 gradually decreases along the axial direction to make the housing 11 have a structure that is narrow at the top and wide at the bottom; the sound guide part 111 is provided at the upper end of the housing 11, and the lower end of the housing 11 is provided with a first contact 112 and a button 113; the first contact 112 is electrically connected to the first circuit module; the button 113 protrudes from the lower end of the housing 11.

[0040] The diameter of the housing 11 gradually decreases along the axial direction, giving it a narrower top and wider bottom structure, which helps to better adapt to the structure of the human ear canal. The sound guide 111 is located at the upper end of the housing 11 to ensure effective sound conduction. A first contact 112 and a button 113 are located at the lower end of the housing 11. The first contact 112 is electrically connected to the first circuit module to ensure charging and control functions. The button 113 protrudes from the lower end of the housing 11 for easy user operation. This design solves the problem of adapting the hearing aid housing 11 to the structure of the charging case 20 while ensuring functionality.

[0041] The diameter of the housing 11 gradually decreases along the axial direction, which can be achieved through mold processing, injection molding, or other methods. The sound guide 111 can be made of a high sound conductivity material and fixed to the housing 11 by welding or bonding. The first contact 112 can be made of metal and connected to the first circuit module via a wire. The button 113 can be made of silicone and fixed to the housing 11 by embedding or bonding.

[0042] This invention utilizes a shell structure 11 that is narrower at the top and wider at the bottom, allowing the hearing aid to better adapt to the shape of the human ear canal and improving wearing comfort. The placement of the sound guide 111 ensures effective sound transmission, while the arrangement of the first contact point 112 and the button 113 guarantees the hearing aid's charging and control functions. Compared to existing technologies, this invention solves the problem of structural compatibility between the hearing aid shell 11 and the charging case 20, ensuring both the hearing aid's functionality and user experience.

[0043] In some implementations, the present invention also proposes that a pull wire 114 is provided at the lower end of the housing 11, one end of the pull wire 114 is fixed on the housing 11, and the free end of the pull wire 114 is provided with a pull wire 114 head.

[0044] By providing a pull cord 114 at the lower end of the housing 11, with one end fixed to the housing 11 and the other end having a pull cord head, users can easily remove the hearing aid assembly by pulling the pull cord head. This feature increases the ease of removing the hearing aid assembly, providing a better user experience, especially for users who need to frequently remove and place their hearing aids.

[0045] Specifically, the pull cord 114 can be made of a durable yet flexible material to ensure it will not easily break or be damaged during use. The tip of the pull cord 114 can be designed in an easy-to-grip shape, such as round or oval, so that the user can easily pull it. The length of the pull cord 114 can be adjusted as needed to ensure that the hearing aid assembly can be easily removed without affecting wearing comfort. As a preferred embodiment, the tip of the pull cord 114 can also be provided with an anti-slip texture to further improve the ease of removing the hearing aid.

[0046] Therefore, by providing a pull cord 114 at the lower end of the housing 11, this invention significantly improves the ease of removing the hearing aid assembly, solving the technical problem in the prior art where the hearing aid assembly is difficult to remove during use. Compared with the prior art, this invention provides a simple and effective solution, significantly improving the user experience, especially for users who need to frequently remove and place their hearing aids.

[0047] In some implementations, the present invention also proposes that the ear cap includes a sound-guiding body 121 and at least one cap body disposed on the sound-guiding body 121. The lower end of the sound-guiding body 121 is provided with a connecting groove 1211 that is sleeved on the sound-guiding part 111. The upper end of the sound-guiding body 121 is provided with at least one sound-guiding hole 1212. The sound-guiding hole 1212 is connected to the connecting groove 1211 to form a sound-guiding channel 1213. The outer diameter of the cap body is larger than the outer diameter of the shell 11.

[0048] The ear cap includes a sound-conducting body 121 and at least one cap body. The lower end of the sound-conducting body 121 has a connecting groove 1211 for fitting a sound-conducting part 111, and the upper end has a sound-conducting hole 1212 that communicates with the connecting groove 1211 to form a sound-conducting channel 1213. The outer diameter of the cap body is larger than the outer diameter of the housing 11. The connecting groove 1211 within the sound-conducting body 121 ensures the stability and sealing of the connection between the ear cap and the hearing aid main unit 10. The sound-conducting hole 1212 communicates with the connecting groove 1211 to form the sound-conducting channel 1213, solving the sound transmission problem. The outer diameter of the cap body is larger than the outer diameter of the housing 11 to ensure stable and comfortable wearing.

[0049] The connecting groove 1211 within the sound guide body 121 can be made of an elastic material to enhance the sealing and stability with the sound guide part 111. The shape and size of the sound guide hole 1212 can be designed according to actual needs, for example, it can be circular, elliptical, or polygonal, to optimize the sound channel transmission effect. The cap can be made of a soft and somewhat elastic material to improve wearing comfort and stability. Furthermore, the outer diameter of the cap can be adjusted according to different users' ear canal sizes to adapt to different wearing needs.

[0050] This invention creates a continuous sound channel 1213 by providing a connecting groove 1211 within the sound-conducting body 121 of the ear cap and a sound-conducting hole 1212 at the upper end of the sound-conducting body 121. This effectively solves the sound transmission problem at the connection between the ear cap and the hearing aid main unit 10. The outer diameter of the ear cap is larger than the outer diameter of the shell 11, ensuring a stable and comfortable fit. Compared with existing technologies, this invention provides an ear cap design with a simple structure that effectively solves the sound transmission problem, significantly improving the user experience of hearing aids.

[0051] In some implementations, the present invention also proposes that the ear cap includes a first cap body 1222 and a second cap body 1221, the first cap body 1222 and the second cap body 1221 are arranged axially on the sound guiding body 121, and the outer diameter of the first cap body 1222 is smaller than the outer diameter of the second cap body 1221.

[0052] The ear cap includes a first cap body 1222 and a second cap body 1221, which are axially disposed on the sound-conducting body 121. The outer diameter of the first cap body 1222 is smaller than that of the second cap body 1221. This design allows different parts of the ear cap to have different outer diameters without affecting the overall size of the ear cap, thus better adapting to the external auditory canal structure during placement and charging, improving the comfort of wearing the hearing aid and the stability of sound transmission.

[0053] Specifically, the first cap 1222 and the second cap 1221 can be made of different materials or have different structures to further optimize wearing comfort and acoustic performance. For example, the first cap 1222 can be made of a softer material to ensure a good fit and comfort, while the second cap 1221 can be made of a firmer material to provide better support and stability. Furthermore, the difference in outer diameter between the first cap 1222 and the second cap 1221 can be adjusted according to the shape of different users' ear canals to achieve personalized customization. Thus, through this diverse design, the needs of different users can be better met, improving the user experience of the hearing aid.

[0054] Compared to existing technologies, the ear cap design proposed in this invention has significant advantages. First, by setting a first cap body 1222 and a second cap body 1221 with different outer diameters on the ear cap, it can better adapt to the structure of the external auditory canal of the human ear, improving wearing comfort. Second, this design helps ensure stable placement and charging of the hearing aid in the charging case 20, avoiding charging inconvenience and poor contact problems caused by an oversized ear cap. Furthermore, by using cap bodies of different materials and structures, the acoustic performance and wearing experience of the hearing aid can be further optimized.

[0055] In some implementations, the present invention also proposes that the outer sides of the first cap body 1222 and the second cap body 1221 are both provided with grooves 1223.

[0056] By providing grooves 1223 on the outer sides of the first cap body 1222 and the second cap body 1221, the flexibility and compressibility of the ear cap can be enhanced, thereby ensuring the air pressure inside and outside the ear canal when wearing the hearing aid main unit 10 and avoiding ear blockage. At the same time, the grooves 1223 make it easier to put the ear cap into the charging case 20, ensuring reliable contact of the charging contacts and avoiding poor contact problems caused by the ear cap being too large.

[0057] Specifically, the outer grooves 1223 of the first cap 1222 and the second cap 1221 can be arranged in a ring or longitudinal form. This design makes the ear cap more easily deformable when subjected to external force, thereby adapting to different ear canal shapes and improving wearing comfort. In addition, the design of the grooves 1223 can also provide a certain buffer space when the ear cap is placed in the charging case 20, avoiding poor contact of the charging contacts due to the ear cap being too tight.

[0058] In a preferred embodiment, the depth and width of the groove 1223 can be adjusted according to the material and size of the ear cap to ensure optimal flexibility and compressibility. Thus, the ear cap can not only adapt to different users' ear canal shapes but also ensure reliable contact of the charging contacts during charging, improving charging efficiency and user experience.

[0059] Compared to existing technologies, this invention effectively solves the technical problems of inconvenience in placing over-ear hearing aids in the charging case 20 and unreliable charging contact by setting a groove 1223 on the outer side of the ear cap. This not only improves the wearing comfort and acoustic performance of the hearing aid but also significantly enhances the user's charging experience, demonstrating high practical value.

[0060] Example 3:

[0061] Based on Embodiment 1 or Embodiment 2, this embodiment further defines the hearing aid components provided in Embodiment 1 or Embodiment 2. See also Figure 1 , Figure 4 This embodiment also provides that a rotating shaft is provided on one side of the base 21, and a bushing fitted onto the rotating shaft is provided on the other side of the cover 22 so that the cover 22 and the base 21 are connected to be closed or opened.

[0062] A pivot on one side of the base 21 engages with a bushing on the other side of the cover 22, allowing the cover 22 to be easily closed or opened with the base 21. This design ensures stable and reliable charging of the hearing aid unit 10 within the charging case 20, while also facilitating user operation. This design solves the problem of closing or opening the hearing aid unit 10 within the charging case 20, ensuring both charging convenience and device reliability.

[0063] The design of the hinge can take many forms, such as a metal hinge or a high-strength plastic hinge. The bushing can be designed as a snap-fit ​​type for a more secure fixation to the hinge, or as a sliding type for easier closing and opening. The materials for the hinge and bushing can be selected according to actual needs, either the same material or different materials, to meet different usage requirements.

[0064] This hinge and bushing design ensures a more stable connection between the cover 22 and the base 21, preventing charging problems caused by a loose cover 22. Simultaneously, this design makes operating the charging case 20 more convenient for users, reducing operational difficulty and improving user experience. Compared to existing technologies, this design not only improves device reliability but also enhances ease of use.

[0065] In some implementations, the present invention also proposes that the base 21 has two first cavities 211, the first cavity 211 including a bottom groove 2111 for accommodating the housing 11 of the hearing aid main unit 10, and a surface groove 2112 for accommodating the first cap 1222 of the hearing aid main unit 10, the surface groove 2112 being connected to the upper end of the bottom groove 2111.

[0066] This utility model includes a base 21 with two first cavities 211. Each first cavity 211 includes a bottom groove 2111 for accommodating the housing 11 of the hearing aid main unit 10, and a surface groove 2112 for accommodating the first ear cap 1222 of the hearing aid main unit 10. The surface groove 2112 is connected to the upper end of the bottom groove 2111. These technical features, by providing dedicated bottom grooves 2111 and surface grooves 2112 to accommodate larger ear caps, ensure that the hearing aid main unit 10 can be smoothly placed into the charging case 20, thereby solving the problem that the overall size of the hearing aid main unit 10 exceeds the standard accommodating range of the charging case 20. This technical solution, by setting two first cavities 211 to respectively accommodate the housing 11 of the hearing aid main unit 10 and the larger ear cap, ensures the correct connection of the charging contacts, improving charging convenience and device reliability.

[0067] The bottom groove 2111 of this invention is used to house the shell 11 of the hearing aid main unit 10, and the surface groove 2112 is used to house the first cap 1222 of the hearing aid main unit 10. The design of the bottom groove 2111 and the surface groove 2112 communicating ensures that the hearing aid main unit 10 can be smoothly placed into the charging case 20, and that the ear cap will not be squeezed during charging. Furthermore, the bottom groove 2111 may also be provided with a second contact 2113 connected to the first contact 112 of the hearing aid main unit 10 to ensure the stability and reliability of charging. The size design of the surface groove 2112 can be adjusted according to the size of the ear cap to accommodate ear caps of different sizes.

[0068] This invention provides a more reasonable and efficient hearing aid charging solution by providing two first cavities 211 on the base 21 to respectively accommodate the housing 11 of the hearing aid main unit 10 and the larger ear tip. This ensures that the hearing aid main unit 10 can be smoothly placed into the charging case 20, solving the problem that the overall size of the hearing aid main unit 10 exceeds the standard capacity of the charging case 20. This improves the convenience of charging and the reliability of the device, avoids the problem of ear tip deformation or accelerated aging due to compression, and enhances the user's charging experience. Compared with existing technologies, this invention provides a more reasonable and efficient hearing aid charging solution.

[0069] In some implementations, this utility model also proposes that a first connecting groove 2115 for accommodating the pull wire 114 of the hearing aid host 10 is provided between two adjacent first cavities 211, and the first connecting groove 2115 is located below the bottom groove 2111; the bottom groove 2111 is also provided with a second contact 2113 connected to the first contact 112 of the hearing aid host 10, and a receiving groove 2114 for accommodating the button 113 of the hearing aid host 10; the second contact 2113 is electrically connected to the second circuit module.

[0070] The technical features of this utility model include: a first connecting groove 2115 for accommodating the pull cord 114 of the hearing aid main unit 10, a first connecting groove 2115 below the bottom groove 2111, a second contact 2113 in the bottom groove 2111, the accommodating groove 2114, and the electrical connection between the second contact 2113 and the second circuit module. These technical features work together to ensure the reliability of the placement of the over-ear hearing aid in the charging case 20 and the charging contact. The first connecting groove 2115 provides additional space to accommodate the pull cord 114, preventing the pull cord 114 from interfering with the placement of the hearing aid. The second contact 2113 in the bottom groove 2111 ensures the electrical connection between the hearing aid main unit 10 and the charging case 20, while the accommodating groove 2114 provides suitable space for the button 113, preventing the button 113 from being accidentally pressed during charging.

[0071] The first connecting slot 2115 can have different cross-sectional shapes, such as rectangular, circular, or other suitable shapes, to ensure that the pull cord 114 can be smoothly placed within it. The second contact 2113 can be made of an elastic material to ensure good contact with the first contact 112 of the hearing aid main unit 10. The size and position of the receiving slot 2114 can be adjusted according to the size and position of the button 113 to ensure that the button 113 is not accidentally pressed within the charging case 20.

[0072] Through these design features, this invention solves the problems of poor placement and charging contact of over-ear hearing aids in the charging case 20. Compared with existing technologies, this invention provides a more reliable hearing aid charging solution, ensuring the stability and reliability of the hearing aid during the charging process.

[0073] In some implementations, the present invention also proposes that the cover 22 has two second cavities 221, and two adjacent second cavities 221 are provided with a second connecting groove. The inner diameter of the second cavity 221 gradually decreases along the axial direction so that the second cavity 221 can accommodate the ear cap of the hearing aid host 10.

[0074] The cover 22 has two second cavities 221, with a second connecting groove between adjacent second cavities 221. This design causes the inner diameter of each second cavity 221 to gradually decrease along the axial direction. This structural design ensures that the over-ear hearing aid main unit 10 can be smoothly accommodated within the second cavity 221. In this way, the over-ear hearing aid is stably placed in the charging case 20, avoiding the problem of not being able to be properly accommodated due to the large size of the over-ear hearing aid. At the same time, the connecting groove design also helps to improve the contact reliability of the charging contacts, preventing the charging effect from being affected by the deformation of the over-ear hearing aid due to compression.

[0075] The two second cavities 221 of the cover 22 are connected by a second connecting slot. This design aims to provide more space and flexibility when placing the hearing aid main unit 10. The inner diameter of the second cavity 221 gradually decreases along the axial direction, meaning that the diameter of the cavity gradually decreases from the entrance to the depth. This allows for better fixation of the ear cap of the hearing aid main unit 10, preventing it from moving during charging. The second connecting slot not only facilitates the smooth placement of the ear cap but also ensures reliable contact of the charging contacts, improving charging efficiency and stability.

[0076] Through the above design, this utility model solves the problems of the inability to properly accommodate over-ear hearing aids in the charging case 20 and the unreliable contact of the charging contacts. Compared with the prior art, this utility model provides a charging case 20 structure that is more suitable for over-ear hearing aids, ensuring stable placement of the hearing aids and reliable charging, and improving the user's charging experience.
