Description

Technical Field

[0001] This utility model relates to the field of hearing aid design and manufacturing technology, specifically to a hearing aid connecting tube and a hearing aid. Background Technology

[0002] Hearing aids are devices used to assist people with hearing impairments. Existing hearing aids can be categorized according to their usage method, including behind-the-ear (BTE), in-the-ear (ITA), and fully in-the-canal (FTC) types. BTE hearing aids are generally composed of small components designed to fit the shape of the human ear. During manufacturing and assembly, these components are typically fixed together, including the connecting tubing that connects to the hearing aid unit and the ear mold.

[0003] Currently, the connection between the hearing aid's connecting tube and the hearing aid unit is typically achieved through either a one-piece molding or a pin-type connector. While a one-piece molding ensures a tight seal and stable connection, it also prevents direct replacement of the connecting tube in case of failure, increasing maintenance costs. Secondly, pin-type connectors are less stable and, due to limitations in expandability, cannot support Bluetooth calling. Over time, deformation or oxidation of the pin-type connector can cause intermittent connection interruptions, affecting the hearing aid's data signal transmission, generating additional noise, and impacting call quality.
