Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einem Lautsprecher.The The invention relates to a motor vehicle with a loudspeaker.
Es sind Kraftfahrzeuge bekannt, welche an der Türinnenseite einen Lautsprecher enthalten, wobei der Lautsprecher an seiner Vorderseite Schall in den Fahrzeuginnenraum abgibt, und wobei die Rückseite des Lautsprechers in den Türhohlraum ragt. Dabei bildet der Türhohlraum das Gehäuse des Lautsprechers. Fahrzeugteile, welche diesen Türhohlraum teilweise begrenzen oder bilden, werden unbeabsichtigt durch Schall, der durch den Lautsprecher auch in den Hohlraum abgegeben wird, angeregt, und können dadurch ungewollte Störgeräusche erzeugen.It Motor vehicles are known, which on the inside of the door a speaker contained, with the loudspeaker on its front sound in the Vehicle interior gives off, and the back of the speaker in the door cavity protrudes. At the same time the door cavity forms the housing of the speaker. Vehicle parts, which this door cavity partially confined or formed, are unintentionally sound, which is delivered through the speaker into the cavity, excited, and can thereby generate unwanted noise.
Dieses Problem könnte durch ein an sich bekanntes starres Lautsprechergehäuse gelöst werden, welches in den Hohlraum integriert wird. Allerdings wären solche Lautsprechergehäuse hinsichtlich ihrer Geometrie an den fahrzeugtypspezifischen Hohlraum anzupassen, was zu hohen Kosten führen würde.This Problem could be be solved by a known per se speaker housing rigid, which is integrated into the cavity. However, such would be Speaker enclosure in terms of their geometry to the vehicle type-specific cavity which would lead to high costs.
Der Erfindung liegt nun die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Kraftfahrzeug anzugeben.Of the Invention is now based on the object, a relation to the State of the art to provide improved motor vehicle.
Diese Aufgabe wird durch die Merkmale des unabhängigen Patentanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den abhängigen Ansprüchen zu entnehmen.These The object is solved by the features of the independent claim. Advantageous developments of the invention are subject to the dependent claims remove.
Die Erfindung beruht auf dem Gedanken, den Hohlraum eines Fahrzeuges, in den die Rückseite eines Lautsprechers ragt, zu trennen oder akustisch zumindest teilweise zu separieren in einen ersten Teilhohlraum, der eher dem Lautsprecher zuzuordnen ist, und einen zweiten Teilhohlraum, der eher nicht dem Lautsprecher zuzuordnen ist, so dass der durch den Lautsprecher in den Hohlraum abgegebene Schall nicht oder zumindest nur gedämpft in den zweiten Teilhohlraum, gelangen kann. Eine Anregung von Fahrzeugteilen, die den zweiten Teilhohlraum begrenzen, durch den Schall des Lautsprechers kann so vermieden oder reduziert werden.The Invention is based on the idea of the cavity of a vehicle, in the back a speaker juts out, separating or acoustically at least partially to separate into a first partial cavity, which is more like the speaker is assigned, and a second part of the cavity, rather than the Speaker is to be assigned, so that through the speaker in the sound emitted by the cavity is not or at least only damped in the second part cavity, can get. A suggestion of vehicle parts, which limit the second part cavity, by the sound of the speaker can be avoided or reduced.
Ein bevorzugtes Kraftfahrzeug umfasst einen Lautsprecher, der in eine Fahrzeuginnenseite integriert ist. Der Lautsprecher gibt an seiner Vorderseite Schall in den Fahrzeuginnenraum ab. Die Rückseite des Lautsprechers ragt in einen Hohlraum, insbesondere des Kraftfahrzeuges oder einer Kraftfahrzeugkomponente, wie beispielsweise einer Türe. Der Hohlraum wird durch eine Tasche in einen ersten Teilhohlraum, der auch durch den Lautsprecher, insbesondere durch die Membran des Lautsprechers, begrenzt ist, und in einen zweiten Teilhohlraum, der im Wesentlichen nicht durch den Lautsprecher, insbesondere nicht durch die Membran des Lautsprechers, begrenzt ist.One The preferred motor vehicle comprises a loudspeaker, which in a Vehicle interior is integrated. The speaker indicates his Front sound in the vehicle interior. The backside of the speaker protrudes into a cavity, in particular of the motor vehicle or a motor vehicle component, such as a door. The cavity gets through a pocket into a first part cavity, which is also through the loudspeaker, in particular through the diaphragm of the loudspeaker, is limited, and in a second partial cavity, which is essentially not through the speaker, especially not through the membrane of the speaker, is limited.
Durch aufwändige Untersuchungen konnte gezeigt werden, dass durch eine solche Tasche oder eine solche Kombination aus Lautsprecher und Tasche in verschieden ausgeführten Hohlräumen und somit auch beim Einsatz in verschiedenen Fahrzeugtypen die Störgeräuschentwicklung reduziert werden kann. Da mit einer einheitlichen Ausführung einer Kombination aus Lautsprecher und Tasche verschiedene Fahrzeugtypen ausgerüstet werden können, ergeben sich Skaleneffekte, die zu einer wirtschaftlichen Umsetzung der Störgeräuschreduzierung beitragen.By complex Investigations have shown that through such a bag or such a combination of speaker and bag in different executed cavities and thus also when used in different vehicle types, the noise development can be reduced. Because with a single execution of a combination speaker and bag different vehicle types are equipped can, there are economies of scale leading to economic implementation the noise reduction contribute.
Besonders wirksam lässt sich die Erfindung in die Praxis umsetzen, wenn der Hohlraum ein Volumen umfasst, das kleiner als fünf Liter ist, und/oder wenn der erste Teilhohlraum ein Volumen umfasst, das größer als ein Liter ist.Especially effective to put the invention into practice when the cavity a Volume that is less than five liters, and / or if the first part cavity comprises a volume larger than a liter is.
Vorzugsweise sind der erste Teilhohlraum und/oder der zweite Teilhohlraum auch durch die Fahrzeuginnenseite begrenzt.Preferably are also the first part cavity and / or the second part cavity bounded by the vehicle interior.
Die Tasche ist vorzugsweise derart ausgeführt, dass sie als Lautsprechergehäuse wirkt. Vorteilhafterweise ist die Tasche aus schwerem schallabsorbierendem Material, wie beispielsweise Schaumstoff, Kunststoff oder Gummi, ausgeführt. Die Tasche ist vorzugsweise derart flexibel und/oder formbar ausgeführt, dass sie in verschiedene Hohlräume beispielsweise verschiedener Fahrzeugmodelle integrierbar ist.The Bag is preferably designed such that it acts as a speaker housing. Advantageously, the bag is made of heavy sound absorbing material Material, such as foam, plastic or rubber, executed. The Bag is preferably designed so flexible and / or formable that she into different cavities For example, different vehicle models can be integrated.
Besonders bevorzugt ist vorgesehen, dass die Tasche eine erste Öffnung aufweist, welche durch den Lautsprecher, insbesondere den Lautsprecher-Korb, den vorderen Rand des Lautsprecher-Korbes oder eine die Lautsprecher-Membran tragende Sicke abgeschlossen ist, insbesondere durch den Lautsprecher-Korb, den vorderen Rand des Lautsprecher-Korbes oder eine die Lautsprecher-Membran tragende Sicke abgedichtet ist oder insbesondere umlaufend daran angebunden ist.Especially it is preferably provided that the pocket has a first opening, which through the speaker, in particular the speaker basket, the front Edge of the speaker basket or a speaker membrane bearing Beading is completed, in particular through the speaker basket, the front edge of the speaker basket or the speaker membrane bearing bead is sealed or in particular circumferentially is connected.
Gemäß einer bevorzugten Weiterbildung der Erfindung weist die Tasche eine zweite Öffnung auf. Zur Verstärkung tiefer Frequenzen nach dem Bassreflex-Prinzip und/oder dem Transmission-Line-Prinzip wird durch diese zweite Öffnung durch den Lautsprecher erzeugter Schall in den Fahrzeuginnenraum abgegeben.According to one preferred embodiment of the invention, the bag has a second opening. to reinforcement low frequencies according to the bass reflex principle and / or the transmission line principle through this second opening Sound generated by the speaker in the vehicle interior issued.
