Abstract (en)
[origin: EP0924959A2] The arrangement has a panel (10) formed essentially of a core layer (11) and upper and lower covering layers (12.1,12.2) covering opposite sides of the core layer. A drive arrangement (16) connected to the panel sets it into vibration under the influence of sound signals. The core layer has an aperture (15) in which the drive arrangement only is integrated.
