Description
rin-Patent-857 205 ist--ein piemelektrisches -Schallumsetzungsgerät mit aus einer Doppelplatte gebildetem, bei der Beanspruchung sich in Form einer Sattelflüche deformierendem piezoelektrischem Element beschrieben, das dadurch gekennzeichnet ist, daß die . Kristalldoppelplatte nur im Schnittpunkt der Diagonalen gelagert ist und daß zwei gegenüberliegende Ecken über einen Bügel mit der Membran verbunden sind, während die beiden anderen Ecken frei schwingen können. In einem bevorzugten Ausführungsbeispiel dieses Erfindungsgedankens wird die Kristalldoppelplatte zwischen zwei Puffern aus elastischem Werkstoff, wie natürlichem oder künstlichem Gummi, synthetischen Harzen, wie Polystyrole od. dgl., mittels eines über die Anordnung hinweggehenden Steges festgeklemmt.rin-patent-857 205 is - a piem-electric -sound conversion device with formed from a double plate, in the case of stress in the form of a Described saddle surface deforming piezoelectric element, which is characterized is that the. Crystal double plate only supported at the intersection of the diagonals and that two opposite corners are connected to the membrane via a bracket while the other two corners can swing freely. In a preferred Embodiment of this inventive concept is the double crystal plate between two buffers made of elastic material, such as natural or artificial rubber, synthetic resins such as polystyrenes od. The like., By means of an over the arrangement overhanging web clamped.
Diese Konstruktion kann gemäß der Erfindung dadurch vereinfacht werden, .daß die Kristalldoppelplatte auf einem einzigen Puffer aus elastischem Werkstoff, wie den vorhererwähnten Stoffen, gelagert, insbesondere aufgeklebt, ist. Es entfallen hierbei der obere Puffer und der die Anordnung zusammenhaltende Steg.According to the invention, this construction can be simplified by .that the double crystal plate on a single buffer made of elastic material, like the aforementioned materials, stored, in particular glued on. It is omitted here the upper buffer and the web that holds the arrangement together.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Gegenstandes der Erfindung. Die Kristalldoppelplatte z ist mit dem Puffer 2 aus elastischem Werkstoff, z. B. synthetischem oder natürlichem Gummi oder Kunststoff, verklebt. Der Gummi :2 selbst ist an dem Boden 3 des Gehäuses q. für die Mikrofonanordnung festgeklebt. An der Doppelplatte z ist wie bei der Anordnung nach dem "Hauptpatent ein Bügel 5 befestigt, der bei 6 mit der Membran 7 verbunden ist, die ihrerseits auf den Rändern 8 des Gehäuses q. festgelegt, z. B. festgeklebt, ist. Es sei noch bemerkt, daß sich diese Lagerung auch bei der von der Rechteckfor m abweichenden Kristallplatte anwenden läßt unter der Voraussetzung, daß sich die Doppelplatte in Form einer Sattelfläche deformiert, so daß auf der Platte ein bei der Beanspruchung in Ruhe bleibender Teil entsteht.The drawing illustrates an embodiment of the subject matter the invention. The double crystal plate z is made of elastic material with the buffer 2, z. B. synthetic or natural rubber or plastic, glued. The rubber : 2 itself is on the bottom 3 of the housing q. glued in place for the microphone arrangement. As in the arrangement according to the "main patent", there is a bracket on the double plate z 5 attached, which is connected at 6 to the membrane 7, which in turn on the edges 8 of the housing q. set, e.g. B. glued is. It should also be noted that use this storage also for the crystal plate deviating from the rectangular shape can be provided that the double plate is in the form of a saddle surface deformed, so that on the plate a part that remains at rest under the stress arises.
