The invention proposes a suspension mount for sound reproduction devices according to the flexural wave principle. Characteristic for such devices is that a panel 10 is provided which must be flexibly attached to a holder 17. The panel 10 is composed of a core layer with a perforated structure, and two cover layers 12 which cover the core layer 11. Since the usual edge borders of conventional loudspeakers must be designed very hard due to the size and weight of the panel 10, the quality of the sound reproduction by such a device is reduced. For that reason the objective of the invention is a suspension mount which avoids the drawbacks of the state of the art. To that end it is proposed to build the suspension mount with the core layer 11 and/or at least one of the cover layers 12. If the core layer 11 itself provides the flexible attachment, it is also possible without any great effort to flexibly attach the panel 10 away from the edge areas. In that case the flexibility of the perforated structure of the core layer 11 is used as a spring element.
