Abstract

Es wird ein Lautsprecher vorgeschlagen, der an rückseitigem Raum als Resonanzvolumen ankoppelt und gleichzeitig rückseitigen Lärmschall abdämpft. Der Lautsprecher umfaßt einen Korb mit Aussparungen, die insbesondere als Strömungskanäle ausgebildet sind. Die Strömungskanäle gewährleisten Druckausgleich sowie gleichzeitig die Dämpfung von Schallwellen höherer Frequenzen.
