Description

Technical Field

[0001] The present application relates to the technical field of hearing aid devices, and in particular to a receiver-mounted hearing aid using a magnetic earplug. Background Art

[0002] The traditional external hearing aid with receiver consists of three parts: the body, the speaker (including the speaker wire) and the earplug. The speaker is connected to the body through the connector led out by the speaker wire, and the earplug is nested in the speaker sound hole. The earplug relies on brute force to nest, and its size is small. It is difficult for elderly users to achieve accurate plugging and unplugging, which brings great inconvenience to the replacement of the earplug. Therefore, it is necessary to propose an external hearing aid with receiver using magnetic earplugs to address the defect that the traditional external hearing aid with receiver is not easy to wear.
