   In der Mitte der Membrane k ist der   Stifthalterarm i befestigt,   der eine Klemme c zum   Festklemmen   des Stiftes oder der Nadel trägt. Der arm j ist an der Kappe b bei m und n drehbar

 gehen, die in die Kappe b eingeschraubt sind. Zwischen den Köpfen der Schrauben und dem   Qucrstück   l sind Federn r eingeschaltet, welche auf das Querstück drücken und es gewöhnlich in einer Mittelstellung halten, wobei in bekannter Weise Fürsorge getroffen ist, die Stellung zu regulieren, um die Grösse der Schwingungen der Membrane mehr oder weniger beeinflussen zu können. Um die Bewegung der Membrane zu beeinflussen, könnten natürlich auch'andere bekannte Mittel als die beschriebenen Verwendung finden. 



   Obwohl es in der Praxis gewöhnlich vorzuziehen ist, Gummi für den Dichtungsring e zu verwenden, kann man auch   ebensogut   Flanell, Filz und andere   Textilstoffe,   die nachgiebig sind, anwenden. 



   Statt der   Klemmscheibe t könnte   man auch irgendwelche anderen Mittel verwenden.

   PATENT-ANSPRÜCHE :
1. Schalldose, deren innere Gehäusewand mit einer elastischen Bekleidung versehen ist, gegen welche sich die Peripherie der Membrane stützt, dadurch gekennzeichnet, dass die elastische   Bekleidung   dem Rande der Membrane gegenüber die Wand des Gehäuses nicht berührt und eine nachgiebige Wand bildet, gegen die sich der Rand der Membrane, stützt.

   In the middle of the membrane k, the pen holder arm i is attached, which carries a clamp c for clamping the pen or the needle. The arm j is rotatable on the cap b at m and n

 go, which are screwed into the cap b. Springs r are inserted between the heads of the screws and the cross piece 1, which press on the cross piece and usually hold it in a central position, care being taken in a known manner to regulate the position in order to more or less the magnitude of the vibrations of the membrane to be able to influence. In order to influence the movement of the membrane, known means other than those described could of course also be used.



   Although in practice it is usually preferable to use rubber for the sealing ring e, one can just as well use flannel, felt and other fabrics which are resilient.



   Instead of the clamping disk t, any other means could also be used.

   PATENT CLAIMS:
1. Sound box, the inner housing wall of which is provided with elastic cladding against which the periphery of the membrane is supported, characterized in that the elastic cladding does not touch the edge of the membrane opposite the wall of the housing and forms a flexible wall against which the edge of the membrane, supports.
