   Von den aus den Fig. 6-9 ersichtlichen Einzelheiten zeigt Fig. 6 ein unten konvexes Stützlager, gegen welches sich eine Traverse von teilweise rundem Querschnitt stützt. Fig. 8 zeigt ebenfalls ein Stützlager mit unten konvexer Fläche, wobei die an dieselbe sich stützende Traverse von rechteckiger Querschnittsform ist. Fig. 7 zeigt ein Stützlager erwähnter Art, welches aus einer dünnen Metallplatte hergestellt'wird. Fig. 9 zeigt ein blockartiges Stützlager, dessen Stützfläche konisch abgeschrägt ist, um die Grösse der Auflagerfl che möglichst zu verringern. Anstatt   Auflagerungs- oder Stützfl.

    chen   von konvexer Gestaltung sowie mit denselben zusammenwirkende Traversen von runder, halbrunder. rechteckiger oder anderer Querschnittsgestaltung an Schalldosen nach Art derjenigen des   Stanmpatentes   in Anwendung zu bringen, könnte die Anwendung vorstehend beschriebener konvexen Auflagerungs- oder Stützflächen natürlich auch an Schalldosen von anderer Konstruktion erfolgen.

   Of the details evident from FIGS. 6-9, FIG. 6 shows a support bearing which is convex at the bottom and against which a cross member of partially round cross-section is supported. FIG. 8 likewise shows a support bearing with a surface that is convex at the bottom, the cross member supported on the same being of rectangular cross-sectional shape. Fig. 7 shows a support bearing of the type mentioned, which is made of a thin metal plate. 9 shows a block-like support bearing, the support surface of which is tapered conically in order to reduce the size of the support surface as much as possible. Instead of supporting or supporting surfaces.

    surfaces of a convex design as well as cross-members of round, semicircular shape that interact with them. To bring rectangular or other cross-sectional design to sound boxes similar to that of the standard patent, the above-described convex bearing or support surfaces could of course also be used on sound boxes of a different design.

Claims

PATENT CLAIMS: 1. Modification of the sound box for speaking machines according to claim 1 of patent no. 40499, characterized in that the same two convex Führungsbezw. Support surfaces are provided, the radius of which is approximately equal to the vertical distance between the connection point of the needle bar on the membrane and that surface of the needle holder EMI2.1 Blocks are formed in order to support the truss or the like. Of round. partly rounder. to serve rectangular or other cross-sectional design, the cross member being connected either directly or indirectly to the needle carrier and the needle bar.

2. Embodiment of the sound box according to the preceding claim I and claim 2 of patent no. 40499. characterized in that the traverse on that side which the EMI2.2
