    Grammophon8challdo8e.   



   Vorliegende Erfindung bezieht sich auf die Ausgestaltung des Nadelbalkens von Grammophonschalldosen und besteht darin, dass der Nadelbalken winkelförmig abgebogen und mit seinem einen Ende an der Membran befestigt, mit seinem anderen Ende aber an dem Schalldosengehäuse gelagert ist. Die Nadel ist an der Knickstelle des Balkens eingesetzt. Die durch die Bewegung der Nadel hervorgerufenen Schwingungen des Balkens werden dabei zur Gänze auf die Membran übertragen, da der Nadelträger selbst frei beweglich ist und an der Verbindungsstelle mit der Membran endigt. 



   In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform in Fig. 1 in Ansicht dargestellt. Fig. 2 zeigt eine Einzelheit in grösserem Massstab. 



   Der Nadelbalken 1 ist   erfindungsgemäss winkelförmig abgebogen und an   der Knickstelle mit der Klemmvorrichtung. 2 für die Nadel versehen. Das eine Ende des Balkens   1   ist an der Membran 3 festgelegt, während das andere Ende in einem Ansatz 4 des Schalldosengehäuses 5 gelagert ist. Die Lagerung erfolgt durch einen Körper 6, der durch Stellschrauben 7 in dem Ansatz 4 festgehalten wird. Bei dem veranschaulichten Aus-   filhrungsbeispiel   ist eine Metallmembran angenommen, welche durch eine sternförmige Pressung entsprechend versteift ist.

    Grammophon8challdo8e.



   The present invention relates to the configuration of the needle bar of gramophone sound boxes and consists in that the needle bar is bent at an angle and is fastened at one end to the membrane, but at its other end it is mounted on the sound box housing. The needle is inserted at the kink of the beam. The vibrations of the beam caused by the movement of the needle are completely transferred to the membrane, since the needle carrier itself is freely movable and ends at the connection point with the membrane.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment in FIG. 1 in a view. Fig. 2 shows a detail on a larger scale.



   According to the invention, the needle bar 1 is bent at an angle and at the kink with the clamping device. 2 provided for the needle. One end of the beam 1 is fixed to the membrane 3, while the other end is mounted in an attachment 4 of the sound box housing 5. It is supported by a body 6 which is held in place in the shoulder 4 by adjusting screws 7. In the illustrated embodiment, a metal membrane is assumed which is correspondingly stiffened by a star-shaped pressing.
