Abstract
When external receivers are used in hearing devices there is a need to suppress feedback further. An ear mold with a receiver is therefore proposed, having a receiver connector including a first snap-fit element at the sound outlet. An adapter is inserted directly into the ear mold and has a second snap-fit element, which is snapped into the first snap-fit element in a manner such that it can be released. A seal, which surrounds the receiver connector completely, is made of a more elastic material than the receiver connector and the adapter and is fitted between the receiver connector and the adapter. It is thus possible to secure the receiver in the ear mold in an acoustically sealed manner, so that there is less feedback. The seal however also ensures that less dirt reaches the receiver.
