Description

Technical Field

[0001] The utility model relates to the technical field of hearing aid design and manufacturing, in particular to a waterproof hearing aid main body. Background Technique

[0002] With the increasingly serious global aging, the number of people with hearing loss is also increasing rapidly. Undoubtedly, hearing aids are one of the most effective ways to compensate for hearing loss. A hearing aid is a hearing aid tool suitable for people with hearing degradation or hearing impairment, which can amplify the external volume and enable the sound to be smoothly transmitted to the auditory center of the brain. Since users need to maintain good hearing, they need to wear hearing aids all the time. During the wearing process, due to sweating in hot weather, sweating during exercise or in a relatively humid environment, the existing hearing aids have poor waterproof performance and are easily damaged due to the intrusion of water or sweat, affecting the service life of the hearing aids. The traditional technology is to provide a waterproof membrane inside the main body of the hearing aid, install the power module and the circuit module inside the waterproof membrane and seal it, and the outer shell of the hearing aid main body is covered on the waterproof membrane. Due to the covering setting of the waterproof membrane, this waterproof structure has a large volume and a large self-weight of its main body part. Moreover, during the wearing and use process, when the button acts on the waterproof membrane, it is extremely easy to cause the waterproof membrane to rupture and the waterproof function to fail.

[0003] The publication number CN210781349U discloses a waterproof hearing aid, including a hearing aid main body. The main body of the hearing aid includes a housing. By providing a receiving groove on the housing, the installation of the button is realized. Then, a sealing member is provided in the receiving groove, so that the button abuts against the sealing member and is sealed and connected, thereby realizing the sealing of the button in a through setting manner and canceling the waterproof membrane bag provided in the main body in the prior art. Although this device solves the problems of the waterproof structure of the existing hearing aid being bulky, complex and difficult to assemble, and high cost, however, its button still adopts a through setting, and it is difficult to achieve complete waterproof sealing to a certain extent, and there is still a possibility of water entering the button, affecting the use efficiency and service life of the hearing aid.
