Description

Schalttrichter. Gegenstand der Erfindung ist ein Schalltrichter aus dünnwandigem Holz, dessen Neuerung darin besteht, daß bei der Eckenverbindung zur Unterstützung der Leimung metallene Kartonnagenietstreifen verwendet werden.Switching funnel. The invention relates to a horn thin-walled wood, the innovation of which is that the corner connection to Metal cardboard rivet strips can be used to support the gluing process.

Die bisher bekannt gewordenen Trichter aus dünnwandigem Holz leiden an dem übelstand, daß sich bei Temperaturveränderung oder starker Erschütterung die Eck.enverbindungen lösen. Diesem Nachteil soll. durch die Hinzufügung der Kartonnagemete vorgebeugt werden. Auch ist durch diese Bauart anderen Holzlautsprechern gegenüber durch die Verwendung schwächsten Holzes nicht nur die Klangfarbe verbessert, sondern auch eine ganz erhebliche Materialersparnis und bedeutend billigere Herstellung ermöglicht.The previously known funnels made of thin-walled wood suffer at the evil that changes in temperature or strong vibration loosen the corner connections. This disadvantage is supposed to. by adding the cardboard boxes be prevented. This design also makes it different from other wooden speakers by using the weakest wood not only improves the timbre, but also a very considerable saving in material and significantly cheaper production enables.

Auf der Zeichnung ist ein Schalltrichter von quadratischem Querschnitt dargestellt, der für verschiedene Zwecke dienen kann und auch in jeder beliebigen anderen Vielecksform ausgeführt werden kann.On the drawing is a bell with a square cross-section which can serve for various purposes and also in any arbitrary other polygonal shape can be executed.

Abb. i zeigt ein Schaubild des Schalltrichters, während die Abb. a die Verbindung eines Nietstreifens mit der Holzes andung und Abb. 3 ein weiteres Muster der Nietstreifen darstellt.Fig. I shows a diagram of the bell, while Fig. A the connection of a rivet strip with the wood andung and Fig. 3 another Represents pattern of rivet strips.

Die abgebildeten Karrtonnagenietstreifen stellen beispielsweise bekannte Muster dar, doch sollen auch andere gebräuchliche Muster zur Anwendung kommen können.The carton rivet strips shown represent known ones, for example Patterns, but other common patterns should also be able to be used.
