Es sind bereits Verbindungen zwischen . Membrangehäuse und Schalleitungsrohr bekannt, die durch Zwischenschaltung eines ausThere are already connections between. Membrane housing and sound conduit pipe known, which by interposing a
- einem elastischen Stoffe bestehenden Zwischengliedes nachgiebig gemacht sind. Aufgabe der vorliegenden Erfindung ist nun, ein solches Zwischenglied so zu gestalten, daß die Schwingfähigkeit des Stiftes und der Membran vollkommen unabhängig von den die- an intermediate link made of elastic material are made yielding. The object of the present invention is now such Design intermediate link so that the ability of the pin and the diaphragm to oscillate completely independent of the die
ίο Schallwellen nach dem Schalltrichter überleitenden festen Teilen wird.ίο Transferring sound waves to the sound trumpet fixed parts.
Die beiliegende Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes durch Fig. ι in Ansicht und durch Fig. 2 im Schnitt.The accompanying drawing shows an embodiment of the subject of the invention through Fig. ι in view and through Fig. 2 in section.
Mit ι ist der Stift bezeichnet, der die Schwingungen unter Vermittlung des auf einem Bolzen gelagerten Stiftträgers 3 und eines von diesem ausgehenden Hebelarmes 4 auf die Schallmembran 2 überträgt. Die Fassung 5 der Schallmembran ist mit der Grundplatte 6 der Wiedergabevorrichtung durch den oben ringsum offenen Hohlring 7 aus einem elastischen Stoffe, wie z. B. Kaut-With ι the pen is referred to, the vibrations with the mediation of on a pin support 3 mounted on a bolt and a lever arm 4 extending therefrom transfers to the sound membrane 2. The version 5 of the sound membrane is with the Base plate 6 of the playback device through the hollow ring 7, which is open all around at the top made of an elastic material, such as. B. Chews
a5 schuk, verbunden. a 5 schuk, connected.
Einer der Ränder des Hohlringes 7 ist bei 8 umgebördelt. Die Umbördelung greift in eine ausgedrehte Vertiefung an der Oberseite des Bodens der Fassung 5 ein. Der andere einwärts gekrümmte Rand des Hohlringes 7 umschließt einen Flachring 9 aus Metall oder anderem harten Stoffe. In diesen Ring sind die Enden mehrerer Schrauben 10 eingeschraubt, deren Köpfe sich gegen die untere Fläche der Grundplatte 6 stützen. Unter der Wirkung der Schrauben 10 und des Flachringes 9 wird der Hohlring 7 nachgiebig gegen die Grundplatte 6 gepreßt.One of the edges of the hollow ring 7 is flanged at 8. The flanging engages in a turned recess on the top of the base of the socket 5. The other inwardly curved edge of the hollow ring 7 encloses a flat ring 9 made of metal or other hard substances. The ends of several screws 10 are screwed into this ring, the heads of which are supported against the lower surface of the base plate 6. Under the Effect of the screws 10 and the flat ring 9, the hollow ring 7 is resilient pressed against the base plate 6.
Es ist hiernach leicht verständlich, daß die beiden Teile 5 und 6 untereinander vollkommen elastisch verbunden und dadurch in vollkommenster Weise unabhängig voneinander gemacht sind.From this it is easy to understand that the two parts 5 and 6 are perfectly mutually exclusive elastically connected and therefore completely independent of each other are made.
Der Schall wird durch das gebräuchliche Rohr 11 nach dem Schalltrichter übergeleitet.The sound is transferred through the usual pipe 11 to the horn.
