Abstract

For a simplified design of electrical line connections in a hearing aid, and in order to avoid solder locations, an anisotropic, electrically conductive, plate-shaped, film-shaped or mat-shaped member is arranged between interconnects of a printed circuit board. Contacts of the hearing aid components are secured to the printed circuit board.
