   @ Untergestell   aufgesetzt werden müssen, z. B. auf   einen gewöhnlichen Tisch. Dabei   wird aber im Gegensatz zum Stammpatente das gemeinsame Gehäuse, welches Laufwerk, Schalleitung und Schalltrichter um- schliesst, nicht nur im Bereiche der   Schalltrichterwandungen   mit   durchbrochenen Wänden ausgebildet.   sondern diese Durchbrechungen werden in voller Höhe der   Gehäusewandung   ausgeführt.

   Es hat sich nämlich bei solchen Spreehmaschinen in   Schatulleuform.   bei welchen meist ein flacher Sehalltrichter zur Anwendung gelangt. dessen Höhe geringer ist als die Höhe der Gehäusewandungen, herausgestellt. dass eine bessere Tonwiedergabe hervorgerufen wird. wenn man die Durchbrechungen in der Kasten- wandung nicht nur in Höhe des Schalltrichters durehführt. sondern über die ganze Höhe der Wandungen des Gehäuses. 



   In der   Zeichnung   ist der   Erfindungsgegenstand   in einer beispielsweisen Ausführungsform dar-

 das äussere Gehäuse. 



   Wie aus der Zeichnung ersichtlich, sind die   Seitenwände 7   und die Stirnwände 2 des Gehäuses als durchbrochene Wände gitter- oder rostartig mit Öffnungen 3 ausgebildet, so dass zwischen der Schallleitung bzw. dem Schalltrichter, der in das Gehäuse eingebaut ist. und diesen Wänden keine schalldämpfenden toten Räume entstehen, sondern die Schwingungen der Zuleitungswände unmittelbar nach aussen frei übertragen werden. Die Innenseite dieser Wände ist mit einem   schalldurchlässigen   Stoff, der zweckmässig farbig   und auch lichtdurchlässig   ist, bespannt.

   @ Underframe must be put on, e.g. B. on an ordinary table. In contrast to the parent patent, however, the common housing, which encloses the drive, sound line and horn, is not only designed with perforated walls in the area of the horn walls. but these openings are made in the full height of the housing wall.

   This is because it has become a box-shaped speaking machine. where mostly a flat cone is used. whose height is less than the height of the housing walls. that a better sound reproduction is produced. if the openings in the box wall are not only made at the height of the bell. but over the entire height of the walls of the housing.



   In the drawing, the subject of the invention is shown in an exemplary embodiment.
 EMI1.4
 the outer case.



   As can be seen from the drawing, the side walls 7 and the end walls 2 of the housing are designed as perforated walls in the manner of a grid or grate with openings 3, so that between the sound conduit or the horn which is built into the housing. and these walls do not create sound-absorbing dead spaces, but rather the vibrations of the supply line walls are freely transmitted to the outside. The inside of these walls is covered with a sound-permeable fabric that is appropriately colored and also translucent.
