Abstract

A sound transducer has a diaphragm cup, a transducer element, and a housing, the diaphragm cup having a diaphragm and a wall. The diaphragm, the wall, and at least one housing part are formed in one piece as a fiber-plastic composite component. At least one first region of the fiber-plastic composite component is reinforced with fibers, and at least one second region of the fiber-plastic composite component is free of fibers, so that waves in the fiber-plastic composite component are at least partly reflected at a transition from the at least one first region to the at least one second region.
