Description

Die Erfindung hat eine Schalleitung für Sprechmaschinen zum Gegenstande, die die Form eines Schraubenganges oder einer Kegelschraube besitzt. Demgegenüber kennzeichnet sich die Erfindung im wesentlichen dadurch, daß die gewundene Schalleitung aus einzelnen halbkreisförmigen Holzrohrbögen zusammengesetzt ist. Das hierdurch gewonnene lange Führungsrohr aus Holz ruftThe invention has a sound line for speaking machines to the subject that the Has the shape of a screw thread or a tapered screw. In contrast, indicates the invention is essentially characterized in that the winding sound line from is composed of individual semicircular wooden pipe arches. The gained thereby long guide tube made of wood calls

ίο einen kräftigen, dabei weichen und wohlklingenden Ton hervor. Zweckmäßig sind die Holzrohrbögen drehbar gegeneinander, damit sich die Länge der Schalleitung in gewissen Grenzen ändern läßt, je nach dem zur Ver-ίο a strong, soft and melodious one Sound. Appropriately, the wooden pipe bends are rotatable against each other, so the length of the sound line can be changed within certain limits, depending on the

t5 fügung stehenden Raum.t5 adjoining room.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestelltThe subject of the invention is shown in the drawing, for example

Die Schalleitung besteht aus einem gewundenen Holzrohr r, dessen Windungen in einem Schraubengang verlaufen.
' Gemäß der Erfindung besteht das Rohr aus einzelnen halbkreisförmigen Rohrbögen b. Jeder Rohrbogen ist aus zwei symmetrischen Hälften zusammengefügt. Die einzelnen Rohrbögen können miteinander verleimt, aber auch gegeneinander drehbar sein. In letzterem Falle läuft der eine Bogen beispielsweise als muffenförmiges Verbindungsstück aus, in das das benachbarte Ende des nächsten Bogens hineinpaßt.The sound conductor consists of a twisted wooden tube r, the turns of which run in a spiral.
' According to the invention, the pipe consists of individual semicircular pipe bends b. Each elbow is made up of two symmetrical halves. The individual pipe bends can be glued to one another, but they can also be rotated against one another. In the latter case, one bend ends, for example, as a sleeve-shaped connecting piece into which the adjacent end of the next bend fits.

An dem Ende können viertelkreisförmige Bogen ν angeordnet sein, uin einen geeigneten Anschluß zu schaffen.Quarter-circular arcs ν can be arranged at the end in order to create a suitable connection.
