ABSTRACT:
A hearing aid has a skeleton, with an outer support element (3), an inner support element (4) and a connecting element (5), on which are arranged at least part of the electronic components (41, 42) of the hearing aid. The two support elements essentially form the end faces (IS, AS) of an irregular frustum. To the support elements is fixed a diaphragm (2) in such a way that it essentially forms the circumferential surface of the frustum. The diaphragm (2) and the skeleton (3, 4, 5) together form a substantially tubular molding cavity, in which a shaped member (1) adapted to the individual auditory canal is molded with a hardening molding compound in the ear of the user. Prior to the molding process the skeleton can be roughly adapted to the individual auditory canal by a suitable deformation of the connecting element (5). The diaphragm (2) is not only gas-permeable and liquid-impermeable at right angles to its main surface.
