Description

359701)359701)

Bei KJinematagraphentheatern mit BiId- und Tonvorführung ist es wesentlich, die Schallquelle so anzuordnen, daß dem Zuhörer die lebenden Bilder als Ausgangspunkt des Schalles erscheinen. Man hat zu diesem Zweck die Sprechtelephone bisher entweder seitlich vor dem Projektionsschirm, oder an der Bildfläche entlang oder hinter diesen angeordnet. Die Schallquelle wird erfindungsgemäß vorIn cinematic theaters with picture and sound demonstration, it is essential to position the sound source so that the listener can see it the living images appear as the starting point of the sound. One has to do this the speaking phones so far either on the side in front of the projection screen, or on the screen arranged along or behind them. The sound source is according to the invention before

to der Projektionswand, aber derart angeordnet, daß die von den Telephonen ausgehenden Schallstrahlen auf die Projektionswand hingerichtet sind, also erst nach Reflexion an der Wand in den Zuschauerraum gelangen.to the projection screen, but arranged so that the outgoing from the telephones Sound rays are executed on the projection screen, so only after reflection on the Wall into the auditorium.

Die Abbildung zeigt ein Ausführungsbeispiel. Das oder die Telephone t sind seitlich oder unterhalb ader oberhalb der Projektionswand oder in einer Kombination dieser Möglichkeit so angeordnet, daß der Schall vermittels der Trichter tr in Richtung der Pfeile α auf die Wand fällt und von dieser in Richtung der Pfeile b in den Zuschauerraum reflektiert wird. Vorteilhaft können die Trichter in die Wände, welche die Projektionswand umgrenzen, eingebaut bzw. gleich eingemauert as sein, so daß die Trichter irei von mechanischer Eigenschwingung sind.The figure shows an exemplary embodiment. The telephone or telephones t are arranged laterally or below vein above the projection wall or in a combination of this possibility so that the sound falls on the wall by means of the funnel tr in the direction of the arrows α and is reflected from this in the direction of the arrows b into the auditorium will. Advantageously, the funnels can be built into the walls that delimit the projection wall or be walled in at the same time, so that the funnels are irei of mechanical natural oscillation.
