Description

Plattensprechmaschine mit zwei Schalldosen Es ist bekannt, daß an Sprechmaschinen bei der Wiedergabe durch zwei Schalldosen eine Klangveredelung erzielt werden kann, wenn man die beiden Schallstifte hintereinander über die Schallplatte während der ganzen Spieldauer in einen bestimmten Zeitabstand führt (vgl. Patentschrift 417 870).Record speaking machine with two sound boxes It is known that at Speaking machines achieved a sound refinement when played back through two sound boxes can be if you put the two sound pens one behind the other over the record leads to a certain time interval throughout the playing time (see patent specification 417 870).

Die Erfindung bezweckt, auf schon in Gebrauch befindliche Sprechmaschinen mit nur einer Schalldose und einem Tonarm einen zweiten mit Schalldose versehenen Tonarm so anbringen zu können, daß die zweite Schalldose bequem in dieselbe Klangrille gesetzt werden kann wie die erste. Dadurch wird es ermöglicht, daß das Tonstück unter Veredelung des Klangcharakters wiedergegeben werden kann, wenn nur der genügende Abstand zwischen den beiden Schalldosen gewahrt wird.The invention aims to apply to speaking machines that are already in use with only one sound box and one tonearm, a second one with sound box To be able to attach the tonearm so that the second sound box comfortably fits into the same sound groove can be set like the first. This enables the clay piece can be reproduced with refinement of the sound character, if only the sufficient Distance between the two sound boxes is maintained.

Gemäß der Erfindung wird (vgl. Abbildung) hinter dem Standort der Plattensprechmaschine mit einem Schallarm ein drehbarer Wandarm b angebracht, der einen zweiten mit Schalldose versehenen Tonarrri a trägt, der bei c drehbar aufgehängt ist und -in den Trichter d endet. Die Verwendung solcher Wandarme ist in arideren Industriezweigen, z. B. in der zahnärztlichen Technik, bekannt, aber neu für den vorliegenden Zweck. Es wird durch diese Neuerung möglich, Koffersprechmaschinen, an denen sonst ein zweiter Schallarm keinen Platz hat, mit zwei Schalldosen zu spielen und so eine Tonfülle zu erreichen, wie sie für Tanzbegleitung oder für die Vorführuni von Musikplatten in größeren Räumen erwünscht ist.According to the invention (see. Figure) behind the location of the Record speaking machine with a sound arm attached to a rotatable wall arm b, the a second sound box provided with a tone array a, which is rotatably suspended at c is and -in the funnel d ends. The use of such wall arms is in other Branches of industry, e.g. B. in dental technology, known but new to the present purpose. This innovation makes it possible to use case speaking machines, otherwise there is no place for a second sound arm to play with two sound boxes and to achieve such a richness of tone as it is for dance accompaniment or for the demonstration university of music records in larger rooms is desirable.

Claims (1)

PA'rrNTANSPRUCH: Plattensprechmaschine mit zwei in derselben Klangrille laufenden Schalldosen, deren zweite den Ton mit genügender Phasenverschiebung und damit den Klangcharakter verbessernd wiedergibt, dadurch gekennzeichnet, daß der zweite Tonarm (a) von einem Wandarm (b) getragen wird und so beweglich angeordnet ist, daß seine Schalldose bequem in dieselbe Klangrille gesetzt werden kann, in der die Schalldose einer üblichen Plattensprechmaschine mit einem Tonarm, z. B. einer Koffersprecl:-maschine, läuft.PA'rrNT CLAIM: Record speaking machine with two in the same sound groove running sound boxes, the second of which the sound with sufficient phase shift and thus reproduces the sound character improving, characterized in that the second tonearm (a) is carried by a wall arm (b) and is so movably arranged is that its sound box can be conveniently placed in the same sound groove in the sound box of a conventional record speaker with a tonearm, z. B. a suitcase machine, runs.
