Description
' Das Patent 347508 betrifft einen Schallappanat, bei dein zum Zwecke der Übertragung von Schallenergie zwischen Medien von sehr stark verschiedener Kompressibilität, z. B. Wasser und Luft mit einer Membran oder Schallplatte ein sehr kleiner und flacher mit Gas gefüllter Raum gekoppelt ist. Als Schalleitung zu einer entfernten Stelle, an der der eigentliche Geber oder Empfänger aufgestellt ist, dient zweckmäßig eine Rohrleitung, die mit dem kleinen Raum durch eine öffnung in Verbindung steht. Die Öffnung· kann auch durch eine nachgiebige Membran verschlossen sein.'' The patent 347508 relates to a sound apparatus, at your for the purpose of transferring sound energy between media from very different compressibility, e.g. B. water and air with a membrane or record is coupled to a very small and flat room filled with gas. as Sound conduction to a remote location where the actual transmitter or receiver is set up is, it is useful to use a pipeline that connects to the small space through a opening communicates. The opening can also be through a flexible membrane to be introverted.
Es hat sich nun gezeigt, daß diese Schallleitung eine störende Rückwirkung auf den aus Membran und Kopplungsraum gebildeten Schallapparat ausübt derart, daß sie die Abstimmung und Dämpfung derselben verändert. Besonders störend macht sich diese Rückwirkung geltend, wenn der kleine und flache Raum mit der Membran in Resonanz gebracht ist. Jede Änderung der Rohrleitung bedingt alsdann eine Veränderung der Abas stimmuDigsverhältnisse.It has now been shown that this sound conduction has a disruptive effect on the The sound apparatus formed from the membrane and the coupling space exercises such a degree that it controls the vote and attenuation of the same changed. This retroactive effect is particularly disturbing when the small and flat space is resonated with the diaphragm. Any change in the pipeline then causes a change in Abas' voting relationships.
Gemäß der Erfindung wird dieser Nachteil dadurch vermieden, daß zwischen Rohrleitung
<und Kopplungsraum bzw. Resonator ein freier Zwischenraum gelassen wird.
Werden mehrere Schallräume hintereinander geschaltet, z. B. hinter den Kopplungsraum noch ein besonderer Resonator, so muß
der freie Raum zwischen diejenigen Teile des Schallweges eingefügt werden, die. einerseits ;
in ihrer Abstimmung konstant sein sollen und die anderseits lediglich die Funktion !
einer Weiterleitung des Schalles auszuüben \ haben.
Um die mechanische Kontinuität der Ein- | richtung zu bewahren, wird zweckmäßig die
durch den Zwischenraum geschaffene Unterbrechungsstelle durch eine Verkleidung im
weitem Abstand von der Schalleitung überdeckt, die gleichzeitig das Innere der Apparatur
gegen das Eindringen von Schmutz o. dgl. schützt.According to the invention, this disadvantage is avoided in that a free space is left between the pipe and the coupling space or resonator. If several sound rooms are connected in series, e.g. B. a special resonator behind the coupling space, the free space must be inserted between those parts of the sound path that. on the one hand ; should be constant in their coordination and on the other hand only the function! a transmission of the sound \ have to exercise.
To ensure the mechanical continuity of the in- | To preserve direction, the interruption point created by the gap is expediently covered by a cladding at a large distance from the sound line, which at the same time protects the interior of the apparatus against the ingress of dirt or the like.
In der Zeichnung ist eine Einrichtung gemäß der Erfindung als Ausführungsbeispiel einfachster Art dargestellt.The drawing shows a device according to the invention as an exemplary embodiment shown in the simplest way.
Es bezeichnet 1 eine Sohallmembran, die das Gehäuse 2 gegen das äußere Medium abschließt. Über eine Öffnung 5 in der Blende 3 ist der Gasraum 4 mit der Schalleitung 6 verbunden. Bei 8 befindet sich zwischen der Hinterwand des Gehäuses 2 und dem Leitungsrohr 6 ein Spalt, der die Rückwirkung des letzteren über die Öffnung 5 auf den Raum 4 verhindert. Als Abschluß des Innenraumes des Apparates gegen die Umgebung ist eine Haube 7 über das Gehäuse 2 derart geschoben, daß sie sich mit ihrem Rande 9 an die Leitung 6 und mit dem Rande 10 an das Gehäuse 2 ringsum anlegt.It denotes 1 a Sohall membrane that the housing 2 closes off from the external medium. Via an opening 5 in the panel 3 the gas space 4 is connected to the sound line 6. At 8 is between the Rear wall of the housing 2 and the pipe 6 a gap, which the reaction of the latter through the opening 5 on the Room 4 prevented. As a closure of the interior of the apparatus from the environment a hood 7 is pushed over the housing 2 in such a way that its edge 9 on the line 6 and with the edge 10 on the housing 2 all around.
