Abstract
Description
Die Erfindung bezieht sich auf ein Lautsprechergehäuse, aufweisend einen Boden und einen Deckel, wobei Boden und Deckel über zwischengesetzte, im Wesentlichen ebene Schallwände mit Schaufenstern untereinander und miteinander verbunden sind und sich im Innern des Gehäuses mehrere Lautsprecher unterschiedlicher Charakteristika befindenThe invention relates to a speaker housing, comprising a bottom and a lid, with bottom and lid over intermediate, substantially flat Baffles with shop windows are interconnected and interconnected and located in the Inside the housing are several speakers of different characteristics
Es ist ein Lautsprechersystem bekannt (DE 693 29 001 T2), bei welchem mindestens drei Lautsprecher in einer festen Relativanordnung entlang einer gekrümmten Oberfläche angeordnet sind, um eine bestimmte Schallausbreitung zu erzeugen.It is a speaker system known (DE 693 29 001 T2), in which at least three Speaker in a fixed relative arrangement along a curved surface are arranged to produce a certain sound propagation.
Bei der vorliegenden Erfindung geht es darum, eine solche Anordnung der einzelnen Lautsprecher eines Systems zu realisieren, so dass das Gehäuse unterschiedlichen Anwendungszwecken und Einbauvorstellungen gerecht wird.The present invention is concerned with such an arrangement of the individual Speaker of a system to realize, so that the case different Application purposes and installation ideas is fair.
Erreicht wird dies bei einem Lautsprechergehäuse der eingangs genannten Art dadurch, dass drei Schallwände in Querschnittsansicht ein gleichschenkeliges Dreieck bilden; die nach vorn gewandte größere Schallwand dem so genannten Front- bzw. Rear-Center zugeordnet ist, die beiden gleich großen Schallwände je nach Anbringungsort dem linken Frontkanal (rechten Rear-Kanal) und dem rechten Front-Kanal (linken Rear-Kanal) zugeordnet sind, und dass Mittel zur Befestigung des Gehäuses an einer Wand oder einem Stativ im hinteren Teil des Gehäuses vorgesehen sind.This is achieved in a loudspeaker enclosure of the type mentioned by, that three baffles in cross-sectional view form an isosceles triangle; the forward facing larger baffle the so-called front or rear center is assigned, the two equal sized baffles depending on the mounting location of the left Front channel (right rear channel) and the right front channel (left rear channel) are assigned, and that means for attaching the housing to a wall or a tripod in the rear part of the housing are provided.
Die Erfindung wird nachfolgend anhand der Zeichnungen beispielsweise erläutert.
In Figur 1 ist ein Lautsprechergehäuse gezeigt. Es hat im Wesentlichen die Form eines
Trapezoid mit einem im Wesentlichen ebenen Deckel 13 und einem entsprechend
ausgebildeten, etwa gleich großen Boden 14. Boden und Deckel haben die Form eines
gleichschenkligen Dreiecks. Boden und Deckel können auch nach vorn hin
auseinanderlaufen.FIG. 1 shows a loudspeaker housing. It essentially has the form of a
Trapezoid with a substantially
Die Abstände zwischen Boden und Deckel werden über Zwischenwände festgelegt, die im Wesentlichen eben ausgebildet sind und mit Schalllöchern oder Schallfenstern ausgebildet sind.The distances between the floor and the lid are determined by intermediate walls, the are essentially flat and with sound holes or sound windows are formed.
Die vordere Schallwand 10 ist mit den relativ großen vorderen Schallöffnungen
ausgebildet. Hinter dieser Schallwand 10 befinden sich die Lautsprecher, der je nach
Anordnung mit Rear-Center oder Front-Center bezeichnet werden.The
Die kleineren Schallwände 11 und 12 sind mit entsprechenden Schallfenstern ausgebildet
und ihnen sind der rechte Rear-Kanal bzw. der linke Front-Kanal einerseits bzw. der
rechte Front-Kanal und der linke Rear-Kanal zugeordnet, was von der Art der Anordnung
im Raum abhängt. Diese Verhältnisse werden durch die Ansicht nach Figur 2 ersichtlich.The
Figur 3 zeigt eine alternative Art einer Wandaufhängung mit einem einzigen Lautsprechergehäuse. Eine Anordnung mit zwei derartigen Gehäusen ist denkbar, wobei dann das zweite System bei Blickrichtung der Figur 3 nach vorn ersetzt wird.Figure 3 shows an alternative type of wall suspension with a single Speaker enclosure. An arrangement with two such housings is conceivable, wherein then the second system is replaced in the direction of the figure 3 forward.
Das Gehäuse ist an den drei Dreiecksecken mit Hilfe von Aluminiumprofilen nach außen hin
abgerundet, wobei diese Profile an den Schallwänden 10, 11 und 12 befestigt sind. Im
hinteren Bereich ist das Aluminiumprofil so ausgebildet, dass dort die elektrischen
Anschlüsse vorgenommen werden können und darüber hinaus auch Befestigungsmittel
zur Verfügung stehen. Es ist an eine Befestigung mit einem Stativ gedacht, aber ebenso
gut ist auch eine Befestigung an einer Wand möglich.The housing is outward at the three triangular corners with the help of aluminum profiles
rounded, these profiles are attached to the
Bei dem Lautsprechergehäuse können drei separate Tonkanäle in einem Gehäuse vereinigt werden, nämlich der linke und der rechte und der Center-Kanal, wobei alle drei Kanäle von separaten Verstärkern mit unterschiedlichen Signalen angesteuert werden können. Der eine Kanal strahlt direkt ab, während die anderen beiden indirekte Strahler sind. Der Schall des linken und des rechten Kanals wird auf große Reflektoren wie Zimmerwände gerichtet und erreicht den Hörer damit vornehmlich als reflektierter indirekter Schall. In the speaker cabinet, three separate audio channels can be combined in one housing are the left and the right and the center channel, all three channels of separate amplifiers with different signals can be controlled. Of the one channel radiates directly, while the other two are indirect radiators. The sound The left and right channels are aimed at large reflectors such as room walls and reaches the listener primarily as reflected indirect sound.
Für eine deutliche Stereo- oder Links-/Rechtstrennung ist einer der Tief-Mittel-Töner beider
indirekt strahlender Kanäle gegenüber dem anderen umgepolt, d.h. 180° phasengedreht.
Um bei niedrigen Frequenzen eine gegenseitige Schallauslöschung durch einen
akkustischen Kurzschluss zu vermeiden, wird die Phase des umgepolten Tief-Mittel-Töners
mit Hilfe von Induktivitäten und Kapazitäten ebenfalls um bis zu 180° gedreht.
Unterhalb von 400 Hz herrscht zwischen den unterschiedlich gepolten Tieftönern
demzufolge nahezu Phasengleichheit, während oberhalb von 400 Hz eine Phasendifferenz
von bis zu 180° besteht.For a clear stereo or left / right separation of one of the low-mid-range sounder of both indirect radiating channels is reversed compared to the other, ie 180 ° phase-rotated.
In order to avoid mutual sound cancellation by an acoustic short circuit at low frequencies, the phase of the reversed low-midrange sounder is also rotated by up to 180 ° with the help of inductors and capacitors. Below 400 Hz there is therefore almost equal phase between the different polarized woofers, while above 400 Hz there is a phase difference of up to 180 °.
