Background

Hearing Aid (Hearing Aid) is a tool that helps the Hearing impaired to improve Hearing impairment and thus improve the ability to communicate with others by amplifying relatively weak sounds that are transmitted into the ear canal of the patient so that the patient can hear the sounds through the remaining Hearing. Hearing aids are classified into behind-the-ear hearing aids, in-the-ear hearing aids, and cartridge hearing aids, depending on the external shape.

In the prior art, the shell of the hearing aid is often assembled by at least two shell members, a plurality of protrusions and grooves are arranged on the matching surfaces of the shell members to form a butt joint structure, and the protrusions and the grooves are connected in a matched mode to form connection between the shell members.

Due to the limitation of the precision of the die and the manufacturing process, the finished product of the shell member often has a certain uneven thickness, and the butt joint structure limits the connection position, so that the shell formed after the shell members are connected often has a step difference (namely uneven butt joint between surfaces) at the connection position of the shell members, and the appearance of the hearing aid is provided with flaws. For an ear canal type hearing aid, the hearing aid needs to be worn in the ear canal of a user, so that discomfort during wearing can be caused due to the existence of the level difference, and the use experience is affected.

On the other hand, the conventional butt joint structure requires a certain wall thickness of the housing, and the larger wall thickness limits the further development of the miniaturization of the hearing aid, such as the in-the-canal hearing aid, which is pursued to be miniaturized.
