Abstract
Description
Die Erfindung betrifft einen Lautsprecher mit wenigstens einem Treiber und wenigstens einem äußeren Schalltrichter.The The invention relates to a loudspeaker with at least one driver and at least one outer horn.
Unter anderem in Einsatzfahrzeugen, wie Polizeifahrzeugen, Krankenwagen und dergleichen, werden Lautsprecher eingesetzt, um akustische Warnsignale aber auch Sprachsignale abzugeben. Bei Polizeifahrzeugen für verdeckte Einsätze müssen solche Lautsprecher innerhalb des Fahrzeugs, beispielsweise im Motorraum, montiert werden. Aufgrund der beengten Platzverhältnisse in modernen Serienfahrzeugen steht hierfür kaum noch Platz zur Verfügung. Es ist daher üblich, Lautsprechertrichter beispielsweise seitlich abzufräsen, um die Lautsprecher an einem speziellen Ort montieren zu können. Eine solche Bearbeitung des Lautsprechertrichters ist aber nur bis zu einem gewissen Grad möglich, ohne den für den speziellen Einsatz erforderlichen Schalldruck zu verlieren.Under other in emergency vehicles, such as police vehicles, ambulances and the like, speakers are used to provide audible warning signals but also deliver voice signals. In police vehicles for covert Calls have to such speakers inside the vehicle, for example in the engine compartment, to be assembled. Due to the limited space in modern production vehicles stands for this hardly any space left. It is therefore common For example, laterally mill the speaker funnel to to be able to mount the speakers in a special location. A Such editing of the speaker funnel is only up to to a certain extent possible, without the for to lose the sound pressure required for the special application.
Mit der Erfindung soll ein auch für beengte Einbauverhältnisse geeigneter Lautsprecher geschaffen werden.With The invention is also intended for cramped installation conditions suitable speakers are created.
Erfindungsgemäß ist hierzu ein Lautsprecher mit wenigstens einem Treiber und wenigstens einem äußeren Schalltrichter vorgesehen, bei dem der Schalltrichter wenigstens abschnittsweise aus flexiblem Material besteht und verformbar ausgebildet ist.According to the invention is this a loudspeaker with at least one driver and at least one external horn provided, in which the horn at least in sections consists of flexible material and is formed deformable.
Indem wenigstens der äußere Schalltrichter verformbar ausgebildet ist, lässt sich der Schalltrichter im Wesentlichen in alle Richtungen verformen, so dass auch Einbauorte genutzt werden können, die mit konventionellen Lautsprechern nicht möglich sind. Dies auch deshalb, da die Bearbeitung eines konventionellen Schalltrichters, beispielsweise durch Abfräsen, nur bis zu einem gewissen Grad möglich ist, ohne den notwendigen Schalldruck zu verlieren. Überraschenderweise hat sich aber bei der Erfindung gezeigt, dass bei einem verformbaren Trichter die Schallführung im Wesentlichen intakt und die Schallaustrittsöffnung nahezu konstant bleibt, so dass auch der Schalldruck gegenüber einem unverformten Schalltrichter im Wesentlichen erhalten bleibt. Bei deutlicher Verformung ist festzustellen, dass der Schalldruck gegenüber dem unverformten Zustand im Wesentlichen erhalten bleibt, es verändert sich lediglich die räumliche Schallabstrahlungsverteilung des Lautsprechers.By doing at least the outer horn deformable is educated, leaves the horn essentially deform in all directions, so that also installation locations can be used, which with conventional Speakers are not possible. This is also because the processing of a conventional horn, for example by milling, only possible to a degree, without losing the necessary sound pressure. Surprisingly, it has become but shown in the invention that in a deformable funnel the sound conduction essentially intact and the sound exit opening remains nearly constant, so that the sound pressure compared to an undeformed horn essentially preserved. With significant deformation, it should be noted that the sound pressure opposite the undeformed state is essentially preserved, it is changing only the spatial Sound emission distribution of the loudspeaker.
In Weiterbildung der Erfindung ist neben dem äußeren Schalltrichter ein innerer Schalltrichter vorgesehen, der wenigstens abschnittsweise aus flexiblem Material besteht und verformbar ausgebildet ist.In Development of the invention is in addition to the outer bell an inner Horn provided, the at least partially from flexible Material is formed and deformable.
Auf diese Weise sind auch bei zwei vorhandenen Schalltrichtern beide Schalltrichter verformbar, so dass eine sehr weitgehende Verformbarkeit des Lautsprechers gewährleistet ist. Es ist darüber hinaus aber auch zweckmäßig, sowohl den inneren als auch den äußeren Schalltrichter aus demselben Material herzustellen, um Diskontinuitäten in der Schallausbreitung durch Veränderung des Trichtermaterials zu vermeiden. Der innere Schalltrichter und der äußere Schalltrichter können beispielsweise Teil eines gefalteten Hornlautsprechers sein, bei dem ein Schalltrichter gefaltet ist und dadurch in einen inneren Schalltrichter und einen äußeren Schalltrichter aufgeteilt ist.On This way are both with two existing horns both Bell funnel deformable, allowing a very extensive deformability of the loudspeaker is. It is about it but also useful, both the inner as well as the outer bell made of the same material to discontinuities in the sound propagation through change to avoid the funnel material. The inner horn and the outer horn can For example, be part of a folded horn speaker at which a horn is folded and thereby in an inner Horn and an external horn divided is.
In Weiterbildung der Erfindung besteht der wenigstens eine Schalltrichter aus elastischem Kunststoff oder Gummi.In Further development of the invention consists of at least one bell made of elastic plastic or rubber.
Auf diese Weise lassen sich die Schalltrichter auf einfache Weise herstellen, beispielsweise durch Spritzguss, und die Materialeigenschaften der Schalltrichter lassen sich durch Veränderung der Materialzusammensetzung in weiten Grenzen einstellen.On this way, the bell can be easily made, For example, by injection molding, and the material properties of the horn can be changed adjust the material composition within wide limits.
In Weiterbildung der Erfindung ist der äußere Schalltrichter mit einem einstückig angeformten Halteflansch versehen.In Further development of the invention is the outer horn with a one piece provided molded retaining flange.
Auf diese Weise wird der Aufbau des Lautsprechers weiter vereinfacht. Der Halteflansch besteht ebenfalls aus dem flexiblen und verformbaren Material, ist gegenüber dem Schalltrichter aber beispielsweise mit deutlich erhöhter Wandstärke und gegebenenfalls zusätzlich verrippt ausgeführt, so dass der Halteflansch im Vergleich zum eigentlichen Schalltrichter nur in geringem Maße verformbar ist und dadurch zuverlässigen Haft bieten kann.On In this way, the structure of the speaker is further simplified. The retaining flange is also made of the flexible and deformable material, is opposite but the horn, for example, with significantly increased wall thickness and possibly additionally executed ripped, so that the retaining flange compared to the actual horn only to a small extent deformable and thereby can provide reliable detention.
