A loudspeaker system for an aircraft cabin for passengers, having a support structure, which includes multiple flexible flat elements, forming the internal walls of the cabin, fastening devices for fastening flat elements to the support structure, so that the flat elements may oscillate. At least one acoustic driver is connected to one or more flat elements, to induce a bending movement in the one or more flat elements. The particular flat element may oscillate as an acoustic diaphragm. The acoustic driver has a film-shaped piezoelectric exciter, which is bonded flatly to the flat element. The flat element bonded to an exciter has a first cover layer, a second cover layer, and a core layer between them. The core layer is subdivided in a plane parallel to the first and second cover layers by a horizontal incision in at least one predefined area.
