 sichert ist.   Er6ndungsgemliss   wird die seitliche Abdichtung des zwischen den Elektroden befindlichen Spaltes, die nötig ist, um ein Herausfallen des   Gruses   zu verhindern, durch einen lose    tibergeschobenen,   Filzring bewirkt. Die Anordnung ergibt den Vorteil, dass die
Membran durch die Abdichtung, die sonst entweder gegen die Membran gepresst oder an ihr befestigt wird, am freien Schwingen nicht behindert ist. Infolge dieser geringen
Dämpfung erhöht sich die Deutlichkeit des Mikrophons. 



   Die Zeichnungen geben eine Ausführungsform des Erfindungsgegenstandes, Fig. 1 im
Schnitt, Fig. 2 in einer Aufsicht auf die feste Elektrode mit übergeschobenem Filzring. b ist die bewegliche Elektrode, die an der Membran a durch Anschrauben befestigt ist.

 is secured. According to the invention, the lateral sealing of the gap between the electrodes, which is necessary to prevent the grit from falling out, is effected by a felt ring that is loosely pushed over it. The arrangement has the advantage that the
The membrane is not prevented from swinging freely by the seal, which is otherwise either pressed against the membrane or attached to it. As a result of this low
Attenuation increases the clarity of the microphone.



   The drawings show an embodiment of the subject matter of the invention, Fig. 1 in
Section, Fig. 2 in a plan view of the fixed electrode with the felt ring pushed over. b is the movable electrode which is attached to the membrane a by screwing.

Claims

The electrode has a circular circumference on the outside and is hemispherical on the inside. hollowed out to accommodate the charcoal c. This lies down on the fixed, grooved electrode d, the outer circumference of which corresponds to the movable one Electrode is circular of the same diameter. The gap f located between the electrodes is sealed by the loosely pushed over felt ring e, here cylindrical. t PATENT.

ANSPBUCH: Grus microphone with a hollow electrode attached to the record, characterized in that the lateral sealing of the grus chamber is brought about by a felt ring slid loosely over the fixed and movable electrode, allowing free movement of one of the electrodes, for the purpose of giving the membrane a freer one Grant swing.
