Description

lnembran-Schallsignal-Apparat, bei dem das Druckmittel durch ein die Gehäusewandung durchdringendes gekrümmtes Zuführungsrohr auf die Mitte der Schallmembran geleitet wird Die Erfindung betrifft eine Weiterausbildung von aus der Patentschrift 328 2o5 bekannt gewordenen Schallsignal-Apparaten, bei denen der Ton dadurch erzeugt wird, daß ein Druckmittel durch ein die Seitenwand eines topfförmigen Gehäuses durchdringendes Krümmerrohr auf die Mitte einer die offene Seite des Gehäuses überspannenden Membran geleitet wird, diese in Schwingungen versetzt und sodann durch einen Schalltrichter entweicht. .Membrane sound signal apparatus in which the pressure medium is passed through a die Curved feed pipe penetrating the housing wall onto the center of the sound membrane The invention relates to a further development of from the patent specification 328 2o5 well-known sound signal devices, in which the sound is generated that a pressure medium penetrates through a side wall of a cup-shaped housing Elbow pipe on the center of a membrane spanning the open side of the housing is conducted, this is set in vibration and then through a horn escapes. .

Auf der Zeichnung ist die Ei-fiiidttng in' den Abb. r und 2 beispielsweise im Schnitt und in Seitenansicht dargestellt, während Abb. 3 und q. etwas abweichende Ausführungen zeigen.On the drawing, the egg-filling in Figs. R and 2 is for example shown in section and in side view, while Fig. 3 and q. something different Show executions.

Das Gehäuse A ist zylindrisch gestaltet und an den beiden offenen Seiten durch Membranen B1, B= geschlossen. Das Druckmittel wird durch ein T-Rohr C zugeführt, dessen. Mündungsteile cl, c= beiderseits in Schneiden in der Mitte der beiden Membranen B1, B2 münden. In der Verlängerung des Zuführungsrohres C ist in der Gehäusewand der Schalltrichter D angeordnet.The housing A is cylindrical and both open Sides through membranes B1, B = closed. The pressure medium is through a T-tube C supplied whose. Muzzle parts cl, c = on both sides with cutting edges in the middle the two membranes B1, B2 open. In the extension of the supply pipe C is arranged in the housing wall of the horn D.

Das Druckmittel durchströmt den Schallapparat in Richtung der Pfeile und erzeugt dabei, wie bekannt, einen weittr agenden Ton. Durch die symmetrische Ausbildung des Gehäuses wird- die Tonbildung günstig beeinflußt, abgesehen davon, daß auch die Reichweite des Tones durch die Verdoppelung der Membranen vergrößert wird.The pressure medium flows through the sound apparatus in the direction of the arrows and, as is well known, produces a far-reaching sound. Due to the symmetrical The formation of the housing is favorably influenced, apart from the fact that that the range of the tone is increased by doubling the membranes will.

Die in den Abb., 3 und 4 in der Draufsicht auf die Trichternfündung dargestellten beiden Ausführungsformen unterscheiden sich von der beschriebenen dadurch, däß drei bzNv. vier Membranen B1, B2, B3 (B4),, 'angeordnet sind und daß der krümmer C sich entsprechend in drei bzw. vier Mündungsrohre cl, c2, c1 (c¢) teilt. Die tonverbessernde symmetrische Gehäuseform ist auch bei dieser Ausführung gewahrt.The one in Figs. 3 and 4 in a plan view of the funnel opening The two embodiments shown differ from the one described due to the fact that three bzNv. four membranes B1, B2, B3 (B4) ,, 'are arranged and that the elbow C is divided into three or four mouth pipes cl, c2, c1 (c ¢) Splits. The sound-enhancing symmetrical housing shape is also in this version preserved.
