Description

Technical Field

[0001] This utility model relates to the field of hearing aid design and manufacturing technology, specifically to a receiver for a hearing aid and a hearing aid itself. 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] With the widespread adoption of Bluetooth technology and smartphones, hearing aid users are increasingly demanding call functionality. However, existing hearing aids typically only have one or two microphones inside the earpiece, which is insufficient to effectively remove external noise during calls, causing significant interference. Furthermore, since the hearing aid is worn behind the ear during calls, the microphones can only pick up a limited volume of the user's speech, resulting in a poor user experience.

[0013] Furthermore, this utility model also discloses a hearing aid, including: a hearing aid main unit, a hearing aid ear mold, and a tubing assembly connecting the hearing aid main unit and the hearing aid ear mold.

[0014] The conduit assembly includes: a conduit, a connector, and a receiver of the hearing aid.

[0015] The receiver and the connector are respectively installed at the ends of the conduit. The connector is electrically connected to the hearing aid main unit, and the other end of the receiver is connected to the hearing aid earmold.

[0016] The connector plug has a PCB board at one end, and the PCB board is provided with a number of electrical contact gold fingers.
