摘要： The present invention provides a flat speaker, in particular in the aerospace sector, with a panel for generating acoustic signals by vibration of the same, and a vibration exciter which is connected to a panel and excites this to vibrate. Here the panel has an edge stiffening. This provides the panel with the required stiffness, particularly against hand pressures, but at the same it guarantees high energy efficiency of the flat speaker.

摘要： A loudspeaker system for an aircraft cabin for passengers has a support structure, which includes multiple flexible flat elements, forming the internal walls of the cabin, and 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.

摘要： The invention pertains to an insulation structure for thermally and acoustically insulating an aircraft that features at least one heavy layer, wherein the insulation structure according to the invention is characterized in that the insulation structure comprises an additional absorption layer, in that the heavy layer is perforated at least in certain areas, and in that the perforated area ratio of the heavy layer is adapted in such a way that the heavy layer is essentially transparent to sound for frequencies below a double-wall frequency of the insulation structure. This makes it possible to dampen sound with low frequencies below the double-wall frequency as effectively as possible.

摘要： An aircraft cabin panel for sound absorption, with a core layer that comprises a plurality of cells that extend in an open manner across the thickness of the core layer and that are separated from each other by cell walls, and with a first cover layer that faces away from the sound field, as well as a second cover layer that faces towards the sound field and that comprises a plurality of perforation holes. The second cover layer is multi-layered and apart from a layer with the perforation also comprises a second layer that acts as a flow resistance device. The second layer is arranged on the outside, and visually closes off the perforation, and the outer layer comprises an air-permeable woven fabric.
