   Österreichische PATENTSCHRIFT   Nu-  17823.   
 EMI1.1 
 
 EMI1.2 
 welche sich den bisher bekannten Membranen gegenüber dadurch besonders auszeichnet, dass die Schallwellen, ohne durch die eigene Klangfarbe der Membran beeinträchtigt zu werden, rein wiedergegeben werden können. Dem Wesen nach besteht die vorliegende Membran aus einer plastischen Masse, z. B. Wachs, Paraffin etc., welche als starke Schichte auf ein im   Mcmbrangehäuso eingespanntes Häutchen aus   organischem Material aufgegossen ist. Bei der Herstellung der Membran wird das organische Häutchen in bekannter Weise in das zweiteilige Membrangehäuse eingespannt und auf das   Häutchen   hierauf der eine oder andere der obengenannten Stoffe aufgegossen.

   Es ist leicht einzusehen, dass die aus   solchem Material hergestellte Membran in   der ihr durch den Rekordstift gegebenen Schwingungslage so lange verbleibt, bis durch Änderung des   Lagenverhältnisses zwischen     Rekordnuten   und Membran eine andere Schwingungslage der Membran bedingt ist. Es braucht wohl nicht erst besonders hervorgehoben zu werden, dass die Membran mit. ihrem

   Austrian PATENT Letters No. 17823.
 EMI1.1
 
 EMI1.2
 which is particularly distinguished from the previously known membranes in that the sound waves can be reproduced in pure form without being impaired by the membrane's own timbre. In essence, the present membrane consists of a plastic mass, e.g. B. wax, paraffin, etc., which is poured as a strong layer on a membrane clamped in the Mcmbrangehäuso made of organic material. During the production of the membrane, the organic membrane is clamped in a known manner in the two-part membrane housing and one or the other of the above-mentioned substances is poured onto the membrane.

   It is easy to see that the membrane made of such a material remains in the vibration position given to it by the record pen until a different vibration position of the membrane is caused by changing the position ratio between the record grooves and the membrane. Needless to say, that the membrane with. her

PATENT-ANSPRUCH : Membran für Tonwiedergabevorrichtungen, dadurch gekennzeichnet, dass dieselbe aus EMI1.4 Membrangehäusc eingespanntes Häutchen aus organischem Material in einer Schicht von so grosser Dicke aufgegossen ist, dass eine Eigenschwingung der Membran unmöglich ist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Membrane for sound reproduction devices, characterized in that the same from EMI1.4 Membrane housing clamped skin made of organic material is cast in a layer of so great a thickness that natural oscillation of the membrane is impossible. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
