Wireless charging hearing aid

Abstract

The invention relates to the technical field of electronic devices, and discloses a wireless charging hearing aid, which comprises a shell, an inner shell arranged on the inner surface of the shell, arechargeable battery assembled on one side of the inner shell, a bracket connected with the rechargeable battery, and a control key movably connected with the bracket. According to the wireless charging hearing aid, induction current is obtained by utilizing an electromagnetic induction technology, so that a built-in battery is charged. Internal components of the shell do not need to be in contact with an external charging head, the sealing performance of the shell is better, complete waterproof and dustproof effects are achieved, and the use adaptability of the wireless charging hearing aidis improved. Due to the fact that the shape and the number of layers of the receiving coil can be flexibly designed according to requirements, and meanwhile the magnetic conductive sheet is adopted toshield the induced magnetic field, the electromagnetic induction efficiency is improved, the negative influence of the induced magnetic field on other components is avoided, all the components in theshell can be arranged at will, and the flexibility of overall appearance design is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a wireless charging hearing aid. Background technique [0002] Hearing aids are electronic devices that enhance the sound amplification function for the hearing impaired. Existing hearing aids are usually wired and require a mechanical interface to charge them. Although the charging interface has a movable dust-proof plug, its sealing still has problems in some special occasions, such as swimming and dusty construction sites, which cannot be used normally. On the one hand, such occasions are accompanied by large noises, and hearing-impaired people need hearing aids with good applicability for normal communication; Shorter lifespan. [0003] Furthermore, because the charging interface often needs to be embedded with a certain depth to fix the charging connector, this greatly limits the flexible design of the volume and shape of the hearing aid. On the one hand, it ...

Problems solved by technology

[0003] Furthermore, because the charging interface often needs to be embedded with a certain depth to fix the charging connector, it greatly limits the flexible design of the volume and shape of the hearing aid.

On the one hand, it increases the design difficulty and cost of the appearance and the arrangement of internal components; on the other hand, because the internal components need to avoid the embedded charging interface, the complexity of the arrangement structure increases, and the plugging and unplugging of the interface will increase mechanical wear and reduce Charging reliability and stability
