Description

Akustischer Schwinger. Gegenstand des Hauptpatentes ist eine Einrichtung zur Schallübertragung unter Wasser, bei der die schwingende Masse zwischen zwei mit der Gehäusewand verbundenen federnden Systemen (Membranen) derart befestigt ist, daß. nur eine Bewegungsfreiheit in der Richtung senkrecht zu der Gehäusewand verbleibt.Acoustic transducer. The subject of the main patent is a device for sound transmission under water, where the oscillating mass is between two with the housing wall connected resilient systems (membranes) so attached is that. only freedom of movement in the direction perpendicular to the housing wall remains.

Gegenstand der Zusatzerfindung ist eine besonders zweckmäßige Bauart eines derartigen Schwingers. Ein Ausführungsbeispiel ist in Abb. i in Ansicht, in Abb. z im Querschnitt dargestellt. Die schwingende Masse besteht aus den Teilen a, und a., der Träger aus den Teilen b, und b=,, d, und dz sind federnde Scheiben von ringförmiger Gestalt. Die Teile a" b, und d, bilden ein Ganzes, ebenso die Teile a,, b, und d.- Diese Teile können leicht durch Guß oder auf der Drehbank hergestellt werden; an der der Schnittlinie f-f entsprechenden Fläche werden sie miteinander verbunden.The subject of the additional invention is a particularly useful design such a transducer. An embodiment is in Fig. I in view, in Fig.z shown in cross section. The oscillating mass consists of the parts a, and a., the carrier from parts b, and b = ,, d, and dz are resilient washers of annular shape. The parts a "b, and d, form a whole, as do the parts a ,, b, and d.- These parts can easily be made by casting or on the lathe will; at the surface corresponding to the line of intersection f-f they become one another tied together.

Der Vorteil liegt in der Einfachheit der Formen der einzelnen Teile. Sie lassen sich daher so genau nach Maß herstellen, daß der fertig zusammengesetzte Schwinger genau die verlangten Eigenschaften hat und in der Massenfabrikation ohne weitere Nacharbeit austauschbar ist. Trotz dieser für viele Zwecke (Unterwasserschalltelegraphie, ohrenärztliche Untersuchungen, wissenschaftliche Zwecke) wertvollen Genauigkeit werden die Schwinger äußerst wohlfeil.The advantage lies in the simplicity of the shapes of the individual parts. They can therefore be made to measure so precisely that the assembled one Schwinger has exactly the required properties and in mass production without further rework is interchangeable. Despite this for many purposes (underwater sound telegraphy, ear medical examinations, scientific purposes) valuable accuracy the Schwinger are extremely cheap.

Selbstverständlich ist es auch ohne weiteres möglich, die innere aus a, und a. bestehende Masse als Träger zu verwenden und den sie umgebenden ringförmigen Teil b1, b, als schwingende Masse.Of course, it is also easily possible to turn the inner off a, and a. to use existing mass as a carrier and the ring-shaped surrounding it Part b1, b, as an oscillating mass.
