ABSTRACT:
In an exemplary embodiment, a first shell has the contours of an individually fitted ear adapter and the second shell has a carrier plate penetrated by openings for adjustment elements of the hearing aid structure. In known devices, the covering of the cavity of the ear adapter has proven unfavorable both cosmetically as well as mechanically. In order to alleviate this, the disclosure provides that the inside space of a cover plate be provided with an internally disposed cavity for the carrier plate whose outside dimensions are smaller than the smallest dimensions to be expected for an individually fitted ear adapter, and that the second shell is significantly larger, so that, after application to the first shell, laterally projecting parts are cut off. The disclosed structure is particularly suited for employment given in-ear hearing aids.
