Die Heuerung betrifft eine Lautsprecheranordnung mit Sehallverzögerung unter Ausnutzung der direkten und rückwärtigen Schallab strahlung und mit zwei symmetrisch zueinander in zwei vorderen Ecken eines Gehäuses» Tisches oder dergl. angeordneten Sehallaustritts8ffnungen, die gegebenenfalls schräg gestellt sein können· Obwohl dieses Verzögerungsprinzip bereits seit langem bekannt ist, konnte bisher hierfür keine praktisch befriedigende Ausführungsform einer Lautsprecheranordnung gefunden werden. Heuerungsgemäß wird eine laut Sprecheranordnung mit Schaltverzögerung derart ausgebildet t daS die beiden Schallaustrittsöffnungen durch eine Schallverzögerungsleitung verbunden sind, die als gebogenes, sich vorzugsweise exponentiell erweiterndes Eohr ausgebildet und durch den hinteren Seil des Sehäuses geführt ist und an deren einem Ende ein lautsprecher angebracht i3t» der mit seiner membranseitigen Öffnung in die Verzögerungsleitung hinein und rückseitig direkt abstrahlt.The hiring relates to a loudspeaker arrangement with visual delay utilizing the direct and rearward sound radiation and with two sound outlet openings symmetrically arranged in two front corners of a cabinet, table or the like, which can optionally be set at an angle. Although this delay principle has been known for a long time, So far no practically satisfactory embodiment of a loudspeaker arrangement has been found for this. Heuerungsgemäß is a loudspeaker arrangement with switching delay formed such t which the two sound outlet apertures are connected by an acoustic delay line which is designed as a curved, preferably exponentially expanding EOHR and passed through the rear cable of Sehäuses and at one end a speaker mounted I3T "the with its membrane-side opening into the delay line and radiates directly from the rear.
Zur Unterstützung der direkten Schallabstrahlung wird zweckmäßig zwischen den beiden Schallaustrittsöffnungen ein weiterer Lautsprecher mit direkter Schallabstrahlung vorgesehen. Bei einer zweckmäßigen Ausführungsform nach der Heuerung sind die beiden Schallaustritts3ffnungen symmetrisch zueinander in zwei vorderen Seken eines Ge-To support the direct sound radiation, it is expedient to place between the two sound outlet openings another loudspeaker with direct sound radiation is provided.

Ein Gehäuse 1 ist auf Füßen 9 angebracht, so daß die Lautsprecheranordnung z.B. als Musiktisch Verwendung finden kann. Ein Lautsprecher 3 ist mit seiner Torderseite an einer "bogenförmig gekrümmten Schallverzögerungsleitung 2 angebracht· Die Schallverzögerungsleitung 2 ist 30 gekrümmt^ daß ihr freies Ende symmetrisch zu ihrem Lautsprecherende liegt, so daß die beiden Schallaustrittsöffnungen 10 verbunden sind. Der Lautsprecher 3 strahlt in Sichtung des Pfeiles in die Schallverzögerungsleitung 2 hinein und in Sichtung des Pfeiles 6 direkt nach außen ab. Aus der Schallverzögerungsleitung 2 tritt der Schall verzögert in Richtung des Pfeiles 8 aus. Zur unterstützung der direkten Schallab strahlung ist ein weiterer Lautsprecher 4 vorgesehen, dessen. Abstrahlrichtung durch den Pfeil 5 angedeutet ist. Die an den Vorderecken das Muaiktisches angebrachten LautSprecheröffnungen 10 können in der üblichen Weise durch Stoff, Gitter o.dgl. abgedeckt sein.A housing 1 is mounted on feet 9 so that the loudspeaker arrangement can be used as a music table, for example Can be found. A speaker 3 is with its front side attached to an "arched sound delay line 2 · the sound delay line 2 is curved so that its free end is symmetrical lies at its loudspeaker end, so that the two sound outlet openings 10 are connected. The loudspeaker 3 radiates into and into the sound delay line 2 as seen by the arrow Sighting of the arrow 6 directly to the outside. The sound emerges from the sound delay line 2 with a delay in the direction of arrow 8. There is another loudspeaker to support the direct sound radiation 4 provided, whose. The direction of emission is indicated by the arrow 5. The ones at the front corners the Muaiktisch attached speaker openings 10 can in the usual way by fabric, grid or the like. be covered.
