Abstract (en)
[origin: EP1085780A2] The door consists of an edge, and a door (1) with a front and back cover sheet (3, 4), held revolving in the edge through hinges. The door works as a loudspeaker, and consists of a rigid, light-weight component with the ability to maintain supplied oscillating energy, and to propagate it in at least one effective surface area which proceeds crosswise to its thickness. One or several transducers (8) are mounted on the component to cause its oscillation.
