Abstract

Erfindungsgemäß wird eine Anschlußkontaktierung für Schallwiedergabeanordnungen nach dem Biegewellenprinzip angegeben. Da die Antriebssysteme 21 solcher Anordnungen hohe Stromstärken erfordern und solche Stromstärken nur von massiven, aber die Biegewellenausbreitung behindernden Anschlußkontaktierungen sachgerecht übertragen werden konnten, war Aufgabe der Erfindung, eine Anschlußkontaktierung anzugeben, welche die Probleme im Stand der Technik beseitigt und außerdem sehr einfach realisiert werden kann. Hierzu wird angegeben, daß wenigstens eine der beiden Deckschichten 12 und / oder die Kernschicht 11 leitfähig Bereiche 17 aufweist, die mit den Leitungen 32 einer Tonsignalquelle verbunden sind. Besonders vorteilhaft ist es, wenn die leitfähigen Bereiche 17 zusammen mit den Komponenten herstellt werden können, die auch sonst zur Herstellung der Kernschicht 11 verwendet werden.
