Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verbessern von Klangeigenschaften in einem Fahrzeug, wobei insbesondere in einem Innenraum des Fahrzeugs auftretende störende Schwingungen gedämpft werden.The The present invention relates to a method and an apparatus for improving sound characteristics in a vehicle, in particular to be damped in an interior of the vehicle disturbing vibrations.
Beim Fahren eines Fahrzeugs, beispielsweise eines Personenkraftwagens, treten häufig Schwingungen oder Vibrationen insbesondere mit relativ niedrigen Frequenzen (z. B. ca. 150 Hz) auf, welche von Insassen des Fahrzeugs als störend empfunden werden können.At the Driving a vehicle, for example a passenger car, Frequent vibrations occur or vibrations, especially at relatively low frequencies (e.g. B. about 150 Hz), which felt by occupants of the vehicle as disturbing can be.
Um
diesem Phänomen
entgegenzuwirken, ist es beispielsweise aus der
Dieses Verfahren ist relativ aufwändig, da an vielen Stellen im Fahrzeug entsprechende Lautsprecher und Mikrofone angeordnet werden müssen, welche auch entsprechend mit Strom versorgt werden müssen.This Process is relatively expensive, because in many places in the vehicle corresponding speakers and Microphones must be arranged which also have to be supplied with power accordingly.

Demgegenüber ist es eine Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Verbessern von Klangeigenschaften in einem Fahrzeug bereitzustellen, welche einfach, kostengünstig und platzsparend zu realisieren sind.In contrast, is It is an object of the present invention, a method and a Device for improving sound characteristics in a vehicle to provide which simple, inexpensive and space-saving to realize are.
Diese Aufgabe wird gelöst durch ein Verfahren nach Anspruch 1 oder 2 bzw. durch eine Vorrichtung nach Anspruch 14 oder 15. Die abhängigen Ansprüche definieren bevorzugte oder vorteilhafte Ausführungsbeispiele der Verfahren bzw. der Vorrichtungen.These Task is solved by a method according to claim 1 or 2 or by a device according to claim 14 or 15. Defining the dependent claims preferred or advantageous embodiments of the method or the devices.
Erfindungsgemäß wird ein Verfahren zum Verbessern von Klangeigenschaften in einem Fahrzeug durch mindestens einen Helmholtzresonator, wobei der mindestens eine Helmholtzresonator zur Dämpfung von im Fahrzeug auftretenden Schwingungen ausgestaltet ist, vorgeschlagen. Der mindestens eine Helmholtzresonator wird dabei entweder in einen vorhandenen Zwischenraum in dem Fahrzeug eingebaut, oder ein in dem Fahrzeug vorhandener Zwischenraum wird zu dem mindestens einen Helmholtzresonator umgebaut. Durch dieses Verfahren ergibt sich eine platzsparende Vorrichtung zum Verbessern der Klangeigenschaften. Unter Umbau ist dabei zu verstehen, dass beispielsweise ein Teil von Wänden des Helmholtzresonators durch Wände des bereits vorhandenen Zwischenraum gebildet werden oder allgemein Abschnitte des Helmholtzresonators durch Abschnitte des bereits vorhandenen Zwischenraums gebildet werden.According to the invention is a Method for improving sound characteristics in a vehicle by at least one Helmholtz resonator, wherein the at least a Helmholtz resonator for damping designed by occurring vibrations in the vehicle proposed. The at least one Helmholtz resonator is either in one existing space installed in the vehicle, or an in The space available to the vehicle becomes the at least one Helmholtz resonator rebuilt. This procedure results a space saving device for improving the sound characteristics. Under conversion is to be understood that, for example, a part of walls of the Helmholtz resonator through walls of the already existing interval or generally Sections of the Helmholtz resonator through sections of the already existing gap are formed.
Es können hier insbesondere passive Helmholtzresonatoren verwendet werden, wodurch die Notwendigkeit einer Stromversorgung entfällt. Der mindestens eine Helmholtzresonator kann dabei ein Dämpfungsmaterial bzw. Dämpfungsmittel wie beispielsweise Glaswolle enthalten.It can here in particular passive Helmholtz resonators are used, eliminating the need for a power supply. The at least a Helmholtz resonator can be a damping material or damping means such as glass wool included.
Der vorhandene Zwischenraum kann dabei beispielsweise ein Zwischenraum in einem Holm des Fahrzeugs, in einer Verkleidung des Fahrzeugs oder in einer Stoßstange des Fahrzeugs sein. Insbesondere in dem Fall, in dem der Helmholtzresonator nicht direkt benachbart zu dem Innenraum des Fahrzeugs vorgesehen ist, wird der Helmholtzresonator bevorzugt in gasdichter Weise mit dem Innenraum gekoppelt, beispielsweise durch ein Rohr, welches bevorzugt eine Membran, die Schwingungen übertragen kann, enthält, oder durch andere Mittel, welche Schwingungen übertragen können.Of the existing gap can, for example, a gap in a spar of the vehicle, in a fairing of the vehicle or in a bumper be the vehicle. Especially in the case where the Helmholtz resonator not directly adjacent to the interior of the vehicle is, the Helmholtz resonator preferably in a gas-tight manner with coupled to the interior, for example by a pipe, which preferably contains a membrane which can transmit vibrations, or by other means which can transmit vibrations.
Die Erfindung wird im Folgenden unter Bezugnahme auf die beigefügte Zeichnung anhand bevorzugter Ausführungsbeispiele näher erläutert. Es zeigen:The Invention will be described below with reference to the accompanying drawings using preferred embodiments explained in more detail. Show it:
