Description

Schalltrichter für Tonwiedergabevorrichtungen. Gegenstand der Erfindung ist ein. Schalltrichter für Tonwiedergabevorrichtungen, Sprechmaschinen, elektrische Lautsprecher u. dgL Es sind bereits SchalItrichter in Form einer mit Gewindegängen versehenen Muschel, in die ein Schallrohr einmündet, bekannt.Horns for sound reproducing devices. Subject of the invention is a. Horns for sound reproduction devices, speaking machines, electric Loudspeakers and the like. There are already switching funnels in the form of one with threads provided clam, into which a sound tube opens, known.

Die Neuerung beruht gemäß der Erfindung darin, daß dieses Schallrohr etwa parallel zur Mündungsfläche der Muschel verläuft, an seinem Ende abgeschrägt und drehbar engebaut ist. Hierdurch ist die Schallrohröffnung zu den Gewindegängen der Muschel einstellbar und mithin die Tonfärbung änderbar.The innovation is based according to the invention in the fact that this sound tube runs approximately parallel to the mouth surface of the mussel, beveled at its end and is rotatable. This opens the sound tube to the threads of the shell adjustable and therefore the tone color can be changed.

Die Zeichnung zeigt schematisch einen solchen Schalltrichter gemäß der Erfindung an einem Ausführungsbeispiel, und zwar Abb, i denselben schaubildlich in Anwendung bei einer Plattensprechmaschine und Abb, z das Schallrohr im Schnitt. Mit dem Sprechmaschinengehäuse a ist der muschelförmige Schalltrichter b durch einen Halter (Abb, i) verbunden. Die Schalldose ist an einem Schallrohr c angeordnet, deren anderes Ende ei (Abb. i und z) abgeschrägt ist. Dieses Schallrohr c verläuft erfindungsgemäß etwa parallel zur Mündungsfläche bi der Muschel b und hat außen eine Wulst c3, mittels der es zum Ändern der Tonfärbung in einem Lagerring c2 der Muschel b drehbar ist.The drawing shows schematically such a horn according to FIG of the invention in one embodiment, namely Fig, i the same graphically in use with a record speaking machine and Fig, z the sound tube in section. With the speaking machine housing a, the shell-shaped horn b is through a Holder (Fig, i) connected. The sound box is arranged on a sound tube c, the other end ei (Fig. i and z) is bevelled. This sound tube c runs according to the invention approximately parallel to the mouth surface bi of the mussel b and has the outside a bead c3, by means of which it is used to change the tone color in a bearing ring c2 of the Shell b is rotatable.
