Abstract

An electromagnetic transducer for generating sound in an electronic hearing aid has a housing containing an electromagnetic drive that has a coil, a drive magnet and an armature arrangement. Further, a membrane arrangement is provided in the housing that is mechanically coupled to the armature arrangement. For reducing vibrations due to the driving and driven parts of the transducer, as well as for improving the efficiency, the membrane arrangement is formed by two separate membranes that are arranged at opposite sides of the drive, are identically fashioned and can be oppositely driven such that the overall mechanical pulse occurring due to the movement of the driven or driving parts is minimized.
