Description

Schalltrichter für Schallwiedergabevorrichtungen, Sprechmaschinen o. dgl. Es ist bekannt, Schalltrichter mit Hilfsmitteln, die zum Erhöhen der Resonanz dienen, zu versehen. So z. B, ist es vorgeschlagen, den Schalltrichter doppelwandig zu machen oder Membranen einzubauen, die- infolge ihres Mitschwingens zum Erhöhen der Resonanzwirkung beitragen. Auch durch den Einbau von Resonanzböden, die man gegebenenfalls mit Aussparungen versah, oder durch Einbau von Resonanzwänden, die fast durchweg mit den Trichterwänden parallel verlaufen, versuchte man die Erhöhung der Ton- und Klangwirkung zu erreichen. Zu demselben Zwecke wurden auch im Innern des Trichters Hohlräume angebracht.Horns for sound reproduction devices, speaking machines o. The like. It is known, horn with aids to increase the resonance serve to provide. So z. B, it is suggested that the bell be double-walled to make or to install membranes, which - as a result of their resonance to increase contribute to the resonance effect. Also by installing soundboards that one if necessary provided with recesses, or by installing resonance walls, the almost entirely parallel to the funnel walls, an attempt was made to raise it to achieve the tone and sound effect. For the same purpose were also in the There are cavities inside the funnel.

Die Erfindung betrifft einen Schalltrichter, in dessen Inneren Resonanzwände angeordnet sind. Die Neuerung beruht erfindungsgemäß darin, daß die Resonanzwände wellenförmig gebogen sind. Mit diesen wellenförmig gebogenen Resonanzwänden wird erreicht, daß die Durchgangsquerschnitte für die Nutzschallwellen verschieden groß sind. Es werden also diese Nutzschallwellen an der einen Stelle zusammengepreßt, während sie an der andern Stelle unter verstärktem Drucke in einen größeren Luftraum treten und dadurch eine größere Luftsäule in Bewegung bringen, wodurch der Ton verstärkt wird. Die wellenförmige Biegung der Zwischenwände ermöglicht außerdem ein besseres Schwingen der Holzfasern, wodurch eine bessere Resonanz erzielt wird.The invention relates to a horn with resonance walls inside are arranged. According to the invention, the innovation is based on the fact that the resonance walls are curved in a wave shape. With these wave-shaped curved resonance walls achieved that the passage cross-sections for the useful sound waves of different sizes are. So these useful sound waves are compressed at one point, while at the other point under increased pressure in a larger air space step and thereby move a larger column of air, which amplifies the sound will. The undulating curvature of the partition walls also enables a better one Oscillation of the wood fibers, which results in a better resonance.

Die Zeichnung zeigt den Gegenstand der Erfindung an einem Ausführungsbeispiel, und zwar Abb. i den Trichter im Längsschnitt, Abb.2 den ganzen Trichter in schaubildlicher Darstellung und Abb. 3 einen Schnitt nach der Linie A-B der Abb. i.The drawing shows the subject matter of the invention in an exemplary embodiment, namely Fig. i the funnel in longitudinal section, Fig.2 the whole funnel in a diagrammatic view Representation and Fig. 3 a section along the line A-B of Fig. I.

Der neue Schalltrichter besteht aus einem Schalltrichter bekannter Art von viereckigem Querschnitt und mit einem Ansatz h. In seinem Inneren können Hohlräume c und d eingebaut sein. Diese Hohlräume sowie die Durchbrüche f und g sind ebenfalls bekannt. In den Trichter sind erfindungsgemäß wellenförmig gebogene Resonanzwände a und b eingebaut. Durch die wellenförmige Biegung der Resonanzwände a und b wird die Schallwirkung verstärkt.The new horn consists of a known type of horn with a square cross-section and an attachment h. Cavities c and d can be built into its interior. These cavities and the openings f and g are also known. According to the invention, resonance walls a and b which are curved in a wave shape are built into the funnel. The wave-like bending of the resonance walls a and b increases the sound effect.
