Abstract
A diaphragm arrangement is disclosed to be fitted to a structural component or fixing ring for the purpose of generating sound. The diaphragm arrangement includes two piezo crystals fitted opposite one another on either side of an electrically conductive diaphragm, which can oscillate, and the piezo crystals are each fastened to the diaphragm. The piezo crystals are each electrically conductively connected to a contact plate on their opposing sides.
