Abstract:
A contact connection for a sound reproduction device according to the flexural wave principle, with a panel (10) which is composed of a core layer (11), a top and a bottom cover layer (12.1, 12.2), where the two cover layers (12) are attached to opposite sides of the core layer (11), and with at least one drive system (23) which is connected to the panel (10) and can be connected to a voice coil (16) by means of two lines (18) characterized in that at least one of the two cover layers (12.1, 12.2) and/or the core layer (11) have conductive areas (17.1, 17.2), and that these conductive areas (17) are conductively connected to the voice coil (16) via the lines (18) and the corresponding connections (25) of the respective drive systems (23) in order to supply electrical current to the voice coil (16).
