Description

Technical Field

[0001] The utility model relates to the technical field of assembly and disassembly of hearing aid shells, in particular to a shell structure of a hearing aid which is convenient for assembly and disassembly. Background Art

[0002] Hearing aids are devices that help the hearing-impaired improve their hearing impairments. They use the principle of a loudspeaker to amplify sounds that were originally inaudible, and then use the residual hearing of the hearing-impaired patient to send the sound to the auditory center of the brain, so that the sound can be felt, bringing great convenience to the hearing-impaired patient.

[0003] Existing hearing aid earphones and host are basically integrated. After the earphones are used for a long time, some sweat and dust will inevitably flow into the inside, making it difficult to clean later, which in turn causes the internal parts to rust, thereby affecting the sound transmission ability of the hearing aid. In addition, the earphone shell is prone to loosening when worn for a long time. Therefore, a shell structure for hearing aids that is easy to disassemble and assemble is proposed.

[0007] As a preferred technical solution of the present utility model, a sound receiver is provided on the outer wall of the upper connecting block, and the sound receiver is electrically connected to the earphone.

[0008] As a preferred technical solution of the utility model, the outer wall of the upper connecting block is provided with one end of a dustproof bushing, the other end of the dustproof bushing is provided with a connecting block body, and the dustproof bushing is mainly made of natural rubber material.

[0009] As a preferred technical solution of the present utility model, the wire is only required to be made of silicone material.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The hearing aid has a shell that is easy to disassemble and assemble. A dustproof bushing is arranged on the outer wall of the upper connecting block so that when the wearer wears the device, the dustproof bushing can isolate external sweat. The first fixing platform and the second fixing platform are arranged on the inner wall of the dustproof bushing, so that sweat flowing into the inside of the device is not easy to corrode parts.

[0012] 2. The hearing aid has a shell that is easy to disassemble and assemble. By arranging a lower fixed locking block and an upper fixed locking block on the outer walls of the upper connecting block and the lower connecting block, when the device is connected and fixed, the upper connecting block and the lower connecting block can be fixed by the sleeve fixing effect between the T-shaped connecting block and the T-shaped fixing groove, thereby enhancing the connection stability of the device. The device is fixed by the T-shaped groove, so that the fixed upper connecting block and the lower connecting block are not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS
