Description

Technical Field

[0001] The utility model relates to the field of hearing aids, in particular to a hearing aid with a multiple noise reduction structure. Background Art

[0002] Hearing aids are electronic products commonly used by people with hearing loss. They can process sound signals according to the user's hearing condition, allowing the user to hear sounds that were originally inaudible or unclear. Existing hearing aids are mainly composed of a hearing aid chip plus a microphone, a receiver, function buttons and a shell.

[0003] When using existing hearing aids, if there is noise, the hearing aids cannot be used normally, which affects the user. In addition, the earplugs of hearing aids are not mobile enough, and sometimes the ears feel painful and uncomfortable if they are inserted at an inappropriate angle. In addition, during wearing, it is easy to sweat in hot weather, sweat during exercise, or in a relatively humid environment such as a bathroom. The existing hearing aids have poor waterproof performance and are easily damaged by the intrusion of water or sweat, which affects the service life of the hearing aids. Utility Model Content
