Abstract
The invention relates to the embodiment of panel loudspeakers working according to the bending wave principle. Such loudspeakers generally consist of an acoustic panel and drivers whereby the drivers are connected to the acoustic panel For the formation of bending waves in the acoustic panel it is essentially important that the drivers do not unnecessarily rigidize the acoustic panel This has led to the arrangement of the drivers at a distance from the acoustic panel in a separate frame. In view of the complexity of such an arrangement, the invention aims at providing a connection between the drivers and the acoustic panel that can be supported directly on the acoustic panel and which does not impede the propagation of the bending waves. This is achieved by connecting the drivers to the acoustic panel only at very few points or by providing elastic member in the fixing area of the drivers. A combination of both embodiments is also described.
