Abstract
A loudspeaker module for a hearing device has a loudspeaker, which has a loudspeaker diaphragm and a drive for the loudspeaker diaphragm, and a housing, in which the loudspeaker is arranged. Furthermore, the loudspeaker module contains an antenna unit, which has an antenna coil having a coil axis, a tubular coil core, which forms a sound channel, and an antenna base plate, in which a sound passage opening that opens into the sound channel is formed. The antenna coil, the coil core and the antenna base plate in this case prescribe an antenna characteristic of the antenna unit. The side wall of the housing on the diaphragm side is in this case formed by the antenna base plate.
