Description

Es ist bekannt, die Übertragung der von den Umlaufteilen eines Sprechmaschinenlaufwerkes herrührenden Geräusche und Erschütterungen auf das Sprechmaschinenge» häuse selbst dadurch zu verhindern, daß das Laufwerk durch schallisolierende Stoffe, die an der Laufwerkplatte des Sprechmaschinengehäuses verankert sind, an dem Gehäuse befestigt ist.It is known to transmit the from the circulating parts of a talking machine drive resulting noises and vibrations on the speaking machine ge » housing itself to prevent the drive through sound-insulating materials that are anchored to the drive plate of the speaking machine housing, to the housing is attached.

to Es hat sich jedoch gezeigt, daß derartige Maßnahmen nicht genügen, um die störenden Nebengeräusche völlig abzudämpfen.However, it has been shown that such measures are not sufficient to prevent the disruptive Completely dampen background noises.

Die Neuerung beruht gemäß der Erfindung darin, daß weitere schalldämpfende Teile zwisehen der Laufwerkplatte und den Tragestangen des Elektromotors angeordnet sind. Durch diese Anordnung ist die Laufwerkplatte mit sämtlichen Umlaufteilen des Laufwerkes·, wie der Plattentellerachse, der Schnurscheibe, ao den Regler und dessen Antrieb, sowie der Lagerung dieser Teile von der eigentlichen Befestigung am Gehäuse noch besonders schallisolierend getrennt, so daß die Schwingungen und deren Geräusche auf das Gehäuse des Sprechapparats nicht übertragen werden. Ein Ausführungsbeispiel des Gegenstandes der Erfindung zeigt die Zeichnung, und zwar inThe innovation is based according to the invention in that additional sound-absorbing parts zwisehen the drive plate and the support rods of the electric motor are arranged. With this arrangement, the drive plate is with all rotating parts of the drive, such as the turntable axis, the cord disc, ao the controller and its drive, as well as the storage of these parts of the actual Attachment to the housing is separated in a particularly sound-insulating manner, so that the vibrations and their noises are not transmitted to the speakerphone housing. An embodiment of the subject matter of the invention is shown in the drawing, namely in

Abb. ι die ganze Anordnung der Triebwerkteile undFig. Ι the whole arrangement of the engine parts and

Abb. 2 die besondere Anordnung der schalldämpfenden Teile.
An Tragestangen 1, welche mit einemFig. 2 the special arrangement of the sound-absorbing parts.
On support bars 1, which with a

Ring 2 vernietet sind, ist mittels Lederriemen 12, Bänder o. dgl. in an sich bekannter Weise 35 der Antriebsmotor 11 befestigt. Ansätze 3 der Stangen 1 durchdringen gemäß der Erfindung unter Zwischenlage schallisolierender Scheiben 5 und 6 in der Weise die Laufwerkplatte 7, daß die Stangen 1 mit der Werk- 40 platte 7 durch Unterlegscheiben 4 und Muttern 10 gegenseitig schallisoliert verschraubt sind. Die Laufwerkplatte 7 ist also vollkommen von dem Trägergestell schallisolierend getrennt, das aus den Stangen 1 und dem 45 Ring 2 besteht. Sie trägt in bekannter Weise die übrigen Teile, wie die Plattentellerachse, deren Antrieb und die vollständige Regleranordnung. Die oberen Enden 3 der Stangen ι haben in bekannter Weise weitere 50 Isolierscheiben 6 und 9 sowie Muttern 10 zur Befestigung am Sprechmaschinengehäuseboden. Ring 2 are riveted by means of leather straps 12, bands or the like in a known manner 35 the drive motor 11 is attached. Approaches 3 of the rods 1 penetrate according to the invention with the interposition of sound-insulating disks 5 and 6 in the manner of the drive plate 7 that the rods 1 with the 40 plate 7 by washers 4 and nuts 10 are screwed mutually soundproof. The drive plate 7 is thus perfect separated from the support frame in a sound-insulating manner, which consists of the rods 1 and the 45 Ring 2 consists. It carries the other parts in a known manner, such as the turntable axis, their drive and the complete controller arrangement. The top ends 3 of the rods ι have a further 50 insulating washers 6 and 9 and nuts 10 in a known manner for attachment to the floor of the speaking machine housing.
