Description

Lautsprecher mit einer nach beiden Seiten auf Schallführungen wirkenden Schalldose Lautsprecher mit einer nach jeder Seite auf eine Schallführung wirkenden Schalldose sind bekannt. Man will durch diese Anordnung erreichen, daß sowohl die unmittelbar als auch die durch die Schalleitung verbreiteten Töne der Schalldose von einer Stelle aus zum Ohr gelangen. Die bekannten Einrichtungen dieser Art haben aber den Nachteil, daß die Schalldose innerhalb der Mündung der Schallführung angeordnet ist, so daß letztere an einer Stelle unterbrochen oder durchbrochen werden muß, wodurch deren Resonanz und die von ihr umschlossene Luftsäule empfindlich gestört werden.Loudspeaker with a sound guide acting on both sides Sound box loudspeaker with one acting on a sound guide on each side Sound boxes are known. One wants to achieve by this arrangement that both the directly as well as the tones of the sound box spread through the sound line get to the ear from one place. The known bodies of this type have but the disadvantage that the sound box is arranged within the mouth of the sound guide so that the latter has to be interrupted or broken through at one point, as a result of which their resonance and the column of air it encloses are severely disturbed will.

Um diesen Übelstand zu vermeiden, sind gemäß der Erfindung die Schalldose und das Ende der einen Schallführung nebeneinander im Anfang der zweiten Schallführung derart angeordnet, daß eine Durchdringung der Schallführungen vermieden ist.In order to avoid this inconvenience, the sound box are according to the invention and the end of one sound guide next to each other in the beginning of the second sound guide arranged in such a way that penetration of the sound guides is avoided.

Der Gegenstand der Erfindung ist nachstehend beschrieben und in der Zeichnung beispielsweise dargestellt.The object of the invention is described below and in Drawing shown for example.

Abb. r ist ein Längsschnitt eines Lautsprechers gemäß der Erfindung und Abb. 2 eine Stirnansicht desselben. Die Zeichnung zeigt einen Lautsprecher mit rundem Gehäuse f, dessen Schalleitung e nach Art eines Hornes gewunden ist und von der einen Seite einer doppelseitig wirkenden Schalldose g in einer oder mehreren Windungen von allmählich wachsendem Querschnitt nach außen zur Mündung h führt. Die Schalldose g liegt seitlich der Schalleitungsmündung h. Die zweite Schallführung a ist so angeordnet, daß ihre kleinere öffnung das Gehäuse f des Lautsprechers und die Mündung 1a der Schalleitung e, sowie die Schalldose ä vollständig umschließt. Im Rahmen der Erfindung kann die Schalleitung e auch eine andere als die gezeichnete, hornartig gewundene Form aufweisen.Fig. R is a longitudinal section of a loudspeaker according to the invention and Fig. 2 is an end view of the same. The drawing shows a loudspeaker with a round housing f, the sound line e of which is wound like a horn and leads from one side of a double-sided sound box g in one or more turns of gradually increasing cross-section outwards to the mouth h. The sound box g lies to the side of the sound line junction h. The second sound guide a is arranged so that its smaller opening completely encloses the housing f of the loudspeaker and the mouth 1a of the sound line e, as well as the sound box ä. In the context of the invention, the sound line e can also have a shape other than the drawn, horn-like, wound shape.
