Preferably the vehicle's audio system acts as the loudspeaker unit.

Abstract (de)

Die Erfindung betrifft eine Vorrichtung zur elektroakustischen Geräuschrückführung für ein Kraftfahrzeug (10) mit einem Schalldrucksensor (12), einer Signalverarbeitungseinheit (14), welche mit dem Schalldrucksensor (12) verbunden ist und Signale vom diesem erhält und verarbeitet, und einer Lautsprechereinheit (16) mit zumindest einem Lautsprecher, welche mit der Signalverarbeitungseinheit (14) verbunden ist. Die Aufgabe, das Motorgeräusch möglichst natürlich und einfach in den Innenraum des Kraftfahrzeugs zu übertragen, wird dadurch gelöst, daß der Schalldrucksensor (12) im Ansaug- (18) oder Abgastrakt des Kraftfahrzeuges (10) angeordnet ist. <IMAGE>
