PATENTAMT.PATENT OFFICE.
Bei den bisherigen Sprechmaschinen ist gewöhnlich der in den Schallkurven wandernde Taststift direkt mit der Membran der Schalldose verbunden; an diese schließt sich der Tonarm an, der dann in den Schalltrichter übergeht. Diese übliche Einrichtung zur Tonerzeugung leidet an einem sehr wesentlichen Übelstande, indem nämlich auch bei den besten Ausführungen störende NebengeräuscheIn the previous speaking machines, the one usually wandering in the sound curves Stylus connected directly to the membrane of the sound box; this is followed by the Tonearm, which then merges into the bell. This common device for sound generation suffers from a very significant drawback, namely, in that even with the best designs, annoying background noises
ίο mit unterlaufen und vor allen Dingen der Ton immer einen blechernen, sozusagen harten Klang besitzt, der neben anderen Ursachen durch die Verwendung des metallischen Tonarmes bedingt wird.ίο with undermining and above all the Sound always has a tinny, so to speak hard sound, which among other causes is caused by the use of the metallic tonearm.
Gegenstand der vorliegenden Erfindung ist nun eine Sprechmaschinenschalldose, die unter Vermeidung eines Schallrohres unmittelbar am Schalltrichter angebracht und mit einem starren stabförmigen Übertragungsmittel zwischen Nadel und Membran versehen ist.The present invention is now a speech machine sound box, which under Avoidance of a sound tube attached directly to the horn and with a rigid one rod-shaped transmission means is provided between the needle and membrane.
Das Neue besteht darin, daß das starre stabförmige Übertragungsmittel in einer Führung derart gelagert ist, daß es von der Nadel achsial hin- und hergehende oder um seine Längsachse drehende Bewegungen empfangen kann.The novelty is that the rigid rod-shaped transmission means in a guide is mounted in such a way that it reciprocates axially from the needle or about its Can receive longitudinal axis rotating movements.
Auf der Zeichnung stellt Fig. 1 schematisch die Vorrichtung in Ansicht dar; Fig. 2 ist ein Schnitt nach Linie A-B und Fig. 3 eine Aufsieht. In the drawing, FIG. 1 shows the device in a schematic view; Fig. 2 is a section along line AB and Fig. 3 is a top view.
α ist die Schallplatte, in deren Kurven der Taststift b läuft. Dieser Taststift greift mit einem Stift oder einer Feder c in einen Einschnitt einer achsial verschiebbar und drehbar gelagerten Welle d ein, an deren Ende sich ein Hebel f befindet, der mit der Membran g der Schalldose h verbunden ist. i ist ein Halter, in dessen Armen oder Stützen die Welle d gelagert ist. Man kann somit unter Einschaltung des starren Zwischengliedes die Horizontalschwingungen des Taststiftes d in Schwingungen des Hebels f übertragen und vermeidet den sonst üblichen Tonarm, da die Schalldose h unmittelbar am Schalltrichter angefügt ist. α is the record in whose curves the stylus b runs. This stylus engages with a pin or a spring c in an incision in an axially displaceable and rotatably mounted shaft d , at the end of which there is a lever f which is connected to the membrane g of the sound box h . i is a holder in whose arms or supports the shaft d is supported. The horizontal vibrations of the stylus d can thus be transferred into vibrations of the lever f with the involvement of the rigid intermediate member and avoid the otherwise usual tonearm, since the sound box h is attached directly to the bell.
Das starre Übertragungsmittel kann durch die Bewegungen des Taststiftes sowohl in Drehbewegungen, wie auch in horizontal hin- und hergehenden Bewegungen versetzt werden.The rigid transmission means can by the movements of the stylus both in Rotary movements as well as horizontally to-and-fro movements are offset.
