Description

Technical Field

[0001] The utility model relates to the field of hearing aids, in particular to a hearing aid charging base. Background Art

[0002] A behind-the-ear hearing aid is a device that helps people with poor hearing improve their hearing. It is designed to be placed behind the ear and inserted into the ear canal through a small earplug to transmit sound to the ear. Behind-the-ear hearing aids can adapt to different hearing needs by adjusting parameters such as volume and frequency.

[0003] Behind-the-ear hearing aids are comfortable and easy to wear and take off, especially for people with sensitive skin or hearing impairment. Secondly, behind-the-ear hearing aids are well concealed and not easily noticed by others, so they will not cause embarrassment or discomfort to the user.

[0004] Existing behind-the-ear hearing aids generally have two power supply methods. One is a built-in rechargeable battery that can be charged externally through an interface, and the other is to install a button battery for use. This hearing aid installed with a button battery needs to be separately provided with a detachable battery compartment cover to facilitate battery replacement. Due to the limited size of the hearing aid, this structural design is relatively limited, which makes the battery compartment cover inconvenient to disassemble and assemble, and the cost of using button batteries is relatively high. Some existing directly rechargeable hearing aids can also be charged through a charging stand, but the existing charging stand needs to be connected to the power supply first, and then the hearing aid can be inserted into the charging stand before it can be used. This method requires a fixed power supply to use, which makes it inconvenient to charge the hearing aid. In addition, the structure of the existing charging stand is relatively complex, resulting in a large size and inconvenient to carry. Utility Model Content
