  Zungenpfeife mit durchschwingender Zunge zur Erzeugung von Tönen in Gasen und   Flüssigkeiten.   



   Bei der den Gegenstand des Stammpatentes bildenden Zungenpfeife, welche mit einer sturr eingespannten Schallplatte als durchschwingende Zunge mit absolutem Randknoten arbeitet, haben Versuche ergeben, dass die der Zunge gegenüber angeordnete Patte in entgegengesetzter Phase zu schwingen bestrebt ist. 



   Da an dieser Platte in ihrer Mitte die   Zuführungsleitung   für das Druckmedium befestigt ist, werden durch diese Schwingungsbestrebungen die Rohrleitungen sowie auch 
 EMI1.1 
 durch der   Nutzeffekt   der Vorrichtung nicht voll ausgenutzt. 



   Vorliegende Erfindung betrifft eine Abänderung des Gegenstandes des Stammpatentes zu dem Zweck, dieser Platte das Mitschwingen ohne Beanspruchung der Zu-   flussleitung   zu ermöglichen. 



   Die Zeichnung veranschaulicht zwei beispielsweise Ausführungsformen der Erfindung. 



   Nach Fig. 1 gelangt das Druckmedium durch eine Öffnung r in einen Raum d und dann durch eine weitere Öffnung a in der diesen Raum gegen die Membran A abschliessenden Platte D in den Zwischenraum beider Platten D und A, wo sich entsprechend des Stammpatentes der Querschnitt erweitert und Öffnungen ('den Austritt des Mediums aus dem Apparat gestatten. Bei e ist die Zunge A durchlocht, um in luftreichem Wasser das Ansammein von schädlichen Gasblasen an dieser Stelle zu verhindern. Fig. 2 zeigt

   Schwingungen   versetzt wird. welche durch die Wände des Hohlkörpers d an die Umgebung   ''ertragen werden.   



     K) ne weitere Tonsteigerung lässt   sich noch dadurch   erreichen, dass   die Abmessungen des Raumes d so gewählt sind, dass er mit der durch die übrigen Apparatkonstanten bedingten Tonfrequenz in Resonanz steht. PATENT ANSPRÜCHE:

  Reed whistle with a swinging tongue for generating tones in gases and liquids.



   In the case of the reed whistle forming the subject of the parent patent, which works with a rigidly clamped record as a swinging tongue with an absolute edge knot, tests have shown that the flap arranged opposite the tongue tries to swing in the opposite phase.



   Since the supply line for the pressure medium is attached to this plate in its center, the pipelines as well as are also due to these oscillation efforts
 EMI1.1
 not fully exploited by the efficiency of the device.



   The present invention relates to a modification of the subject matter of the parent patent for the purpose of enabling this plate to oscillate without stressing the inflow line.



   The drawing illustrates two exemplary embodiments of the invention.



   According to Fig. 1, the pressure medium passes through an opening r into a space d and then through a further opening a in the plate D closing this space against the membrane A into the space between the two plates D and A, where the cross-section expands according to the parent patent and openings ('allow the medium to escape from the apparatus. At e the tongue A is perforated in order to prevent the accumulation of harmful gas bubbles at this point in air-rich water. Fig. 2 shows
 EMI1.2
   Vibrations are added. which are carried through the walls of the hollow body d to the environment ''.



     No further increase in tone can be achieved in that the dimensions of the room d are chosen so that it is in resonance with the tone frequency caused by the other apparatus constants. PATENT CLAIMS:
 EMI1.3
 and liquids according to patent no. 77447, characterized in that the plate (D) opposite the tongue is designed as a fixed, freely movable record in the middle
