Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Geräuschgestaltung bei einem Kraftfahrzeug der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a device for noise shaping in a motor vehicle in the preamble of claim 1 specified type.
Eine
derartige Vorrichtung ist dabei beispielsweise aus der
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, welche variablere akustische Übertragungseigenschaften besitzt.task The present invention is a device of the initially mentioned type to create more variable acoustic transmission properties has.
Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung zur Geräuschgestaltung bei einem Kraftfahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The The object is achieved by a device for noise in a motor vehicle with the Characteristics of claim 1 solved. Advantageous embodiments with appropriate and non-trivial further education of the Invention are specified in the subclaims.
Eine Vorrichtung zur Geräuschgestaltung bei einem Kraftfahrzeug, welche variablere akustische Übertragungseigenschaften besitzt, ist erfindungsgemäß dadurch geschaffen, dass wenigstens ein Unterraum eine schaltbare Trenneinrichtung umfasst, mittels welcher der Unterraum zur Anpassung der Schallübertragung in wenigstens einen ersten und einen zweiten Teilraum teilbar ist. Mit anderen Worten umfasst die Vorrichtung zur Geräuschgestaltung eine schaltbare Trenneinrichtung, mittels welcher das Volumen eines Unterraums variierbar ist. Hierdurch kann die auf die schwingfähigen Elemente wirkende Kraft verändert und die schwingfähigen Elemente in eine neue Gleichgewichtslage gebracht werden. Auf diese Weise ändert sich das akustische Übertragungsverhalten der Vorrichtung bzw. der Schallübertragungseinrichtung. Die Trenneinrichtung kann beispielsweise derart an ein Anregungssignal eines Schaltrohrs der Brennkraftmaschine angepasst sein, dass sich die beim Schalten des Schaltsaugrohrs entstehenden akustischen Artefakte – beispielsweise Pegelsprünge oder Sprünge einzelner Motorordnungen – am Schalleintritt der Vorrichtung bzw. im Innenraum des Kraftfahrzeugs vermeiden lassen.A Device for noise shaping in a motor vehicle, which more variable acoustic transmission properties own, is inventively created by at least one subspace comprises a switchable separating device, by means of which the subspace to adapt the sound transmission is divisible into at least a first and a second subspace. In other words, the device includes noise shaping a switchable separating device, by means of which the volume of a Subspace is variable. This allows the on the vibratory Elements acting force changed and the vibratory Elements are brought into a new equilibrium position. To this Way, the acoustic transmission behavior changes the device or the sound transmission device. The separator may, for example, to an excitation signal be adapted to a switching tube of the internal combustion engine that the acoustic artifacts created when switching the intake manifold - for example, level jumps or jumps of individual engine orders - at the sound inlet avoid the device or in the interior of the vehicle.
