Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug, umfassend ein Lautsprechersystem mit einem aktiven Schallwandler, der akustisch an einen Resonanzraum angekoppelt ist, welcher zumindest in Teilen durch einen Hohlraum innerhalb einer Tragstruktur des Kraftfahrzeuges gebildet ist.The invention relates to a motor vehicle, comprising a loudspeaker system with an active sound transducer, which is acoustically coupled to a resonant space, which is formed at least in part by a cavity within a support structure of the motor vehicle.
Aus der
Die
Insbesondere bei dem Einsatz von Bassboxen, welche viel Bauraum benötigen, ist es technisch sehr aufwändig, den Schallwandler zwischen zwei aneinandergrenzende Teilen der Tragstruktur des Kraftfahrzeuges anzuordnen.In particular, in the use of bass boxes, which require a lot of space, it is technically very complicated to arrange the transducer between two adjoining parts of the support structure of the motor vehicle.
Aufgabe der Erfindung ist es, ein Kraftfahrzeug mit einem Lautsprechersystem anzugeben, bei welchem ein aktiver Schallwandler konstruktiv einfach im Kraftfahrzeug an der Tragstruktur des Kraftfahrzeuges angeordnet werden kann, wobei trotzdem ein ausreichendes Sound-Volumen zur Verfügung steht.The object of the invention is to provide a motor vehicle with a speaker system in which an active transducer can be arranged structurally simple in the motor vehicle on the support structure of the motor vehicle, while still a sufficient volume of sound is available.
Die Erfindung ergibt sich aus den Merkmalen der unabhängigen Ansprüche. Vorteilhafte Weiterbildungen und Ausgestaltungen sind Gegenstand der unabhängigen Ansprüche. Weitere Merkmale, Anwendungsmöglichkeiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, sowie der Erläuterung von Ausführungsbeispielen der Erfindung, die in den Figuren dargestellt sind.The invention results from the features of the independent claims. Advantageous developments and refinements are the subject of the independent claims. Other features, applications and advantages of the invention will become apparent from the following description, as well as the explanation of embodiments of the invention, which are illustrated in the figures.
Die Aufgabe ist mit einem Kraftfahrzeug dadurch gelöst, dass der Schallwandler an einem Querträger der Tragstruktur positioniert ist, welcher mit zwei Längsträgern der Tragstruktur verbunden ist, wobei ein Hohlraum des Querträgers mit den Hohlräumen der beiden Längsträgern den Resonanzraum bildet. Dabei sind Träger, die sich im Wesentlichen in Fahrtrichtung des Fahrzeugs erstrecken als Längsträger und Träger, die sich im Wesentlichen quer zur Fahrtrichtung erstrecken als Querträger bezeichnet. Diese Anordnung des Schallwandlers hat den Vorteil, dass der Schallwandler, der nur innerhalb einer einzigen Teilstruktur der Tragstruktur des Kraftfahrzeuges angeordnet ist, besonders erschütterungsfest angebracht ist. Dies kann mit einfachen konstruktiven Mitteln erfolgen. Trotzdem wird unter Nutzung der Hohlräume der beiden an dem Querträger sich anschließenden Längsträger ein ausreichender Resonanzraum für das Lautsprechersystem bereitgestellt.The object is achieved with a motor vehicle in that the sound transducer is positioned on a cross member of the support structure, which is connected to two longitudinal members of the support structure, wherein a cavity of the cross member with the cavities of the two side rails forms the resonance space. In this case, carriers which extend substantially in the direction of travel of the vehicle are referred to as side members and carriers which extend essentially transversely to the direction of travel as cross members. This arrangement of the sound transducer has the advantage that the sound transducer, which is arranged only within a single substructure of the support structure of the motor vehicle, is mounted particularly vibration resistant. This can be done with simple structural means. Nevertheless, a sufficient resonance space for the speaker system is provided using the cavities of the two adjoining the cross member longitudinal beam.
Vorteilhafterweise ist der Schallwandler annähernd mittig an dem Querträger positioniert, wobei je ein Längsträger an einem der Enden des Querträgers befestigt ist. Durch diese Ausgestaltung wird das maximale akustische Volumen bereitgestellt. Insbesondere diese symmetrische Ausrichtung des Resonanzraumes erlaubt eine gute Akustik im Fahrzeuginnenraum.Advantageously, the sound transducer is positioned approximately centrally on the cross member, wherein each one longitudinal member is attached to one of the ends of the cross member. This configuration provides the maximum acoustic volume. In particular, this symmetrical alignment of the resonance chamber allows good acoustics in the vehicle interior.
In einer Ausgestaltung ist der Schallwandler zur akustischen Kopplung mit seiner Rückseite an dem Querträger angekoppelt, d. h. die Rückseite des Schallwandlers strahlt in das Hohlraumvolumen des Querträgers und der mit dem Querträger verbundenen Längsträger ab. Unter der Rückseite des Schallwandlers ist die einem Hörer abgewandte Seite zu verstehen. Durch diese Anordnung ist die Übertragung der akustischen Schwingungen in den Resonanzraum und somit in den Fahrzeuginnenraum besonders vorteilhaft.In one embodiment, the acoustic transducer is coupled with its rear side to the cross member for acoustic coupling, d. H. the back of the transducer radiates into the cavity volume of the cross member and the side member connected to the cross member. Under the back of the transducer is the side facing away from a listener to understand. By this arrangement, the transmission of the acoustic vibrations in the resonance chamber and thus in the vehicle interior is particularly advantageous.
In einer Variante ist der Schallwandler Bestandteil einer Bassbox des Lautsprechersystems. Die vorgeschlagene Anordnung des Schallwandlers eignet sich insbesondere für Bassboxen, da diese aufgrund der niedrigen Frequenzen ein großes akustisches Volumen benötigen. Dieses große Volumen wird durch den vom Querträger und den beiden Längsträgern gebildeten Hohlraum ausreichend bereitgestellt.In one variant, the sound transducer is part of a bass box of the speaker system. The proposed arrangement of the sound transducer is particularly suitable for bass boxes, since they require a large volume of acoustic due to the low frequencies. This large volume is provided sufficiently by the cavity formed by the cross member and the two side members.

Obwohl die Erfindung im Detail durch bevorzugte Ausführungsbeispiele näher illustriert und erläutert wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen. Es ist daher klar, dass eine Vielzahl von Variationsmöglichkeiten existiert. Es ist ebenfalls klar, dass beispielhaft genannte Ausführungsformen wirklich nur Beispiele darstellen, die nicht in irgendeiner Weise als Begrenzung etwa des Schutzbereichs, der Anwendungsmöglichkeiten oder der Konfiguration der Erfindung aufzufassen sind. Vielmehr versetzen die vorhergehende Beschreibung und die Figurenbeschreibung den Fachmann in die Lage, die beispielhaften Ausführungsformen konkret umzusetzen, wobei der Fachmann in Kenntnis des offenbarten Erfindungsgedankens vielfältige Änderungen beispielsweise hinsichtlich der Funktion oder der Anordnung einzelner, in einer beispielhaften Ausführungsform genannter Elemente vornehmen kann, ohne den Schutzbereich zu verlassen, der durch die Ansprüche und deren rechtliche Entsprechungen, wie etwa weitergehenden Erläuterungen in der Beschreibung, definiert wird.Although the invention has been further illustrated and explained in detail by way of preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention. It is therefore clear that a multitude of possible variations exists. It is also to be understood that exemplified embodiments are really only examples that are not to be construed in any way as limiting the scope, applicability, or configuration of the invention. Rather, the foregoing description and description of the figures enable one skilled in the art to practice the exemplary embodiments, and those of skill in the knowledge of the disclosed inventive concept may make various changes, for example as to the function or arrangement of particular elements recited in an exemplary embodiment, without Protection area defined by the claims and their legal equivalents, such as further explanations in the description.
