Description

Technical Field

[0001] This utility model relates to a hearing aid, specifically a hearing aid with magnetic charging function. Background Technology

[0002] Hearing aids commonly use micro-USB interfaces or metal contacts for charging, both of which present numerous practical problems. Micro-USB interfaces require users to accurately insert the plug, which is difficult for elderly users with impaired vision or poor hand dexterity, easily leading to inaccurate insertion or even plug damage. Furthermore, the small size of the micro-USB connector requires precise control during insertion and removal, making it easy to misalign or apply excessive force, potentially damaging the hearing aid. In addition, some hearing aid products use dedicated charging cases to address plug alignment issues, but this introduces new problems such as increased size, portability, and the need for multiple devices. This not only inconveniences users when traveling and using the hearing aid, but also prevents charging if the charging case is lost or damaged, affecting normal use.

[0003] While traditional metal contact charging eliminates the need for plugging and unplugging, the charging contacts still require precise alignment. These exposed contacts are susceptible to environmental factors such as sweat, dust, and oxidation, leading to unstable charging, poor contact, or even complete failure to charge. Furthermore, because the contacts require a compatible charging dock, universal charging cables cannot be used directly, forcing users to carry the charging dock separately, creating another form of inconvenience.

[0004] Therefore, the existing charging methods for hearing aids have many problems, such as difficulty in aligning the interface, difficulty in inserting the micro plug, the large size of the Type-C interface which is not conducive to the integration of small hearing aids, and the reliance on the charging base which makes the device complicated. There is an urgent need for a more convenient, reliable and space-saving charging method to improve the overall user experience of hearing aids. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hearing aid with magnetic charging function, so as to solve the problems existing in the background art.

[0006] The hearing aid with magnetic charging function of this utility model is achieved through the following technical solution, including the hearing aid body and the magnetic charging socket.

[0007] The hearing aid body is C-shaped, and the magnetic charging socket is located at the lower end of the hearing aid body. The built-in battery inside the hearing aid body is charged through the magnetic charging socket.

[0008] As a preferred technical solution, the magnetic charging female connector includes a positive electrode pad and a negative electrode pad;

[0009] The positive electrode pad is connected to the positive electrode copper pillar, and the surface of the positive electrode copper pillar is plated with gold; the negative electrode pad is connected to the N-pole magnet; the positive electrode copper pillar and the negative electrode magnet are arranged coaxially to form a magnetic electrode.

[0010] As a preferred technical solution, the magnetic charging socket is fixed to the circuit board inside the hearing aid body using SMT technology.

[0011] As a preferred technical solution, the diameter of the magnetic charging female socket is 4.2mm and the height is 1.65mm.

[0012] As a preferred technical solution, the bottom of the hearing aid body is provided with a groove, and the magnetic charging female seat is embedded in the groove with its outer surface flush with the bottom surface of the hearing aid body.

[0013] The beneficial effects of this utility model are:

[0014] This invention significantly improves upon the difficulties in interface alignment and cumbersome operation encountered in existing hearing aids during charging by introducing a magnetic charging structure. The magnetic charging female connector automatically and precisely aligns with the charger end via its built-in N-pole magnet, enabling a "blind insertion" operation without visual or manual alignment, greatly enhancing the convenience for elderly users and those with mobility impairments. Compared to traditional metal contact charging methods, this invention employs a coaxial magnetic electrode structure in its charging interface design, providing excellent contact stability and oxidation resistance, further improving charging efficiency and reliability.

[0015] This invention's magnetic charging socket can be directly integrated onto the circuit board inside the hearing aid body using SMT technology. This not only saves installation space and meets the stringent requirements for ultra-thin and miniaturized hearing aids, but also eliminates the need for a dedicated charging case. Users only need one matching magnetic charging cable to charge their hearing aids in any situation, avoiding the inconvenience, increased cost, and accessory dependency issues associated with charging cases. This design is particularly suitable for the application needs of portable hearing aids.

[0016] Meanwhile, this solution effectively avoids the problem of difficult-to-insert micro-USB interface plugs and the limitation of integrating the larger Type-C interface into ultra-small hearing aids, achieving the goal of providing a reliable charging solution while maintaining a lightweight appearance. The overall structure is simple, the interface is sealed, and the connection is reliable, fully solving the problems of complex structure, inconvenience of use, and poor durability of traditional hearing aid charging methods.
