Description

Akustisches Signalinstrument Die Erfindung betrifft ein akustisches Signatinstrument, insbesondere für Kraftfahrzeuge, mit einer mehrteiligen Membran, die aus einem am Gehäuse befestigten Membranring und einer mit der frei schwingbaren Ringöffnung derselben verbundenen Membranscheibe besteht, und mit einem Mitschwinger. Die Erfindung besteht nun darin, daß der Mitschwinger an der Verbindungsstelle zweier Membranteile sitzt.Acoustic signal instrument The invention relates to an acoustic signal Signature instrument, especially for motor vehicles, with a multi-part membrane, which consists of a diaphragm ring attached to the housing and one with the freely oscillating one Ring opening of the same connected membrane disc consists, and with a co-oscillator. The invention consists in the fact that the co-oscillator at the junction of two Membrane parts sits.

Dieser Mitschwinger schwingt .in einer anderen Amplitude als ein Mitschwinger, der in üblicher Weise am Stößelkopf angeordnet wurde. Er wird also bei gleicher Größe eine andere Art Oberton erzeugen, die bei richtiger Ausbildung des Gehäuses einen günstigeren Gesamtton erzeugen läßt. Auch wird der weitere Vorteil erhalten, daß der Mitscliwinger bei gleichem Außendurchmesser dieselbe Wirkung mit einem kleineren Gewicht hervorruft, da er einen Kreisring bildet.This co-oscillator oscillates at a different amplitude than a co-oscillator, which was arranged in the usual way on the ram head. So he will be at the same Size will produce a different kind of overtone, if the housing is designed correctly can produce a more favorable overall tone. Also the further advantage is obtained, that the Mitscliwinger with the same outside diameter has the same effect with a smaller one Causes weight because it forms a circular ring.

In der Zeichnung sind zwei Ausführungsformen dargestellt.Two embodiments are shown in the drawing.

Abb. i und 2 zeigen Schnitte durch die erste Form und Abb. 3 einen Schnitt durch die zweite.Fig. I and 2 show sections through the first shape and Fig. 3 one Cut through the second.

Es ist a der am Gehäuse befestigte Membranring, .der durch den sich trichterförmig erweiternden Membranteil b mit einer Membranscheibe c verbunden. ist, an die der Stößel d angreift. Gemäß Abb. i und 2 ist an der Verbindungsstelle der Teile b und c ein Mitschwinger e vorgesehen, der einen nach. außen sich verjüngenden Ring bildet. Dieser hat vier nach innen vorspringende Ansätze f, mit denen er an der Verbindungsstelle von b und c befestigt ist. Auf diese Weise bildet der Mitschwinger eine nach außen reichende Erweiterung der Membranscheibe c.It is a membrane ring attached to the housing, through which Funnel-shaped widening membrane part b connected to a membrane disc c. is on which the plunger d engages. According to fig. I and 2 is at the junction of parts b and c a co-oscillator e provided, one after. outside tapered Ring forms. This has four inwardly protruding approaches f, with which it is at the junction of b and c is attached. In this way the co-oscillator forms an outwardly extending widening of the membrane disc c.

Bei der Ausführungsform nach Abb. 3 ist der Mitschwinger an der Verbindungsstelle von a und b angeordnet.In the embodiment according to Fig. 3, the co-oscillator is arranged at the junction of a and b .

Der Mitschwinger kann eine beliebige Form haben, z. B. auch als Hohlkörper ausgebildet sein.The co-oscillator can have any shape, e.g. B. also as a hollow body be trained.
