Modular hearing aid

Wolfgang Kopke; Manfred Müller; Wolfgang Schmidt; Albert Eggert; Erwin Gahleitner; Gerhard Raupach

A hearing aid has a circuit board having conductor strips thereon; first plug-in elements mounted on the circuit board and being electrically connected to selective conductor strips; a plurality of circuit board-supported modular structural units; and second plug-in elements mounted on each circuit board-supported modular structural unit. The first plug-in elements cooperate with respective second plug-in elements for securing selected circuit board-supported modular structural units on the circuit board.
