Description
Die Erfindung betrifft ein kugelförmiges Lautsprecher gehäuse mit Horntrichter nach dem Oberbegriff des Patent anspruchs.The invention relates to a spherical loudspeaker housing with horn funnel according to the preamble of the patent demanding
Solche Lautsprechergehäuse sind aus der FR-PS 605 534 bekannt. Dort ist lediglich ein Schallwandler vorgesehen, der in den Horntrichter hineinstrahlt. Aus der FR-PS 25 44 949 sind zwei an einem Horntrichter nicht auf einer Achse angeordnete Schallwandler bekannt, die jedoch in einem eckigen Gehäuse gleichgerichtet eingebaut sind. Bei diesen bekannten Gehäusetypen erfolgt die Schallabstrahlung entweder nur durch einen Lautsprecher oder auf mehreren Schallachsen.Such loudspeaker housings are from FR-PS 605 534 known. There is only one sound transducer, that shines into the horn funnel. From the FR-PS 25 44 949 are two on a horn funnel not on one Axis arranged sound transducers known, however, in are installed in the same direction as a square housing. At These known types of housings are used for sound radiation either only through one speaker or on several Sound axes.
Aufgabe der Erfindung ist es daher, ein Lautsprechergehäuse anzugeben, das den Schall mehrerer Lautsprecher auf derselben Achse abstrahlt.The object of the invention is therefore a loudspeaker housing specify the sound of multiple speakers emits the same axis.
Durch die Schallabstrahlung auf einer Achse ist die Ver besserung des Wirkungsgrades bei bestimmten Frequenzen möglich.Due to the sound radiation on one axis, the ver improvement in efficiency at certain frequencies possible.
Ausführungsbeispiele der Erfindung und in den Figuren darge stellte werden im folgenden näher erläutert.Embodiments of the invention and Darge in the figures are explained in more detail below.
Es zeigenShow it
Fig. 1 einen Schnitt durch die Lautsprecherachse des Gehäuses mit zwei aktiv betriebenen Lautsprechermembranen; FIG. 1 is a section through the speaker axis of the housing with two active-operated speaker diaphragms;
Fig. 2 einen Schnitt durch die Lautsprecherachse eines anderen Ausführungsbeispiels des Ge häuses mit einer passiv betriebenen Laut sprechermembran; Fig. 2 shows a section through the speaker axis of another embodiment of the Ge housing with a passively operated speaker membrane;
Fig. 3 die Ansicht eines zweifach gefalteten Horn trichters. Fig. 3 is the view of a double folded horn funnel.
Fig. 1 zeigt ein Lautsprechergehäuse nach der Erfindung, bei dem zwei angetriebene Lautsprecher durch eine Trennwand entkoppelt eingebaut sind. Einer der Lautsprecher strahlt direkt nach außen, der andere in den Hornrichter hinein. Dadurch wird die Abstrahlung beider Lautsprecher auf der selben Schallachse erreicht. Fig. 1 shows a speaker cabinet according to the invention, in which two powered speakers are installed decoupled by a partition. One of the speakers shines directly outwards, the other into the horn judge. As a result, the radiation from both speakers is achieved on the same sound axis.
Fig. 2 zeigt ein anderes Lautsprechergehäuse nach der Erfindung, in welches zwei Lautsprecher entgegengesetzt eingebaut sind. Fig. 2 shows another speaker cabinet according to the invention, in which two speakers are installed opposite.
Einer der Lautsprecher strahlt direkt nach außen, der andere in den Horntrichter hinein. Eine der beiden Lautsprecher membranen kann passiv betrieben werden.One of the speakers shines directly outwards, the other into the horn funnel. One of the two speakers membranes can be operated passively.
Auch hier erfolgt die Abstrahlung beider Lautsprecher auf derselben Schallachse.Here, too, both speakers are emitted same sound axis.
Fig. 3 zeigt ein doppelt gefaltetes Horn, welches mit jeder der beiden Lautsprecheranordnungen kombiniert werden kann. Fig. 3 shows a double folded horn, which can be combined with any of the two speaker arrangements.
