 EMI2.1 
 Bewegung in vertikaler Richtung geführt. An diesen Zapfen greift eine Zugstange an, die mit einem Arm eines auf dem Ansatz des Gehäuses G gelagerten Hebels verbunden ist. Der freie Arm des Hebels trägt ein Laufgewicht L, das verschiebbar und feststellbar ist, um den Druck, mit dem die obere Kontaktplatte gegen die untere gepresst wird, regeln zu können. Wie aus Fig. 4 ersichtlich, geht der elektrische Strom von   +   Pol in die obere Platte A über die Spitzen in die untere Platte P und von da   über-Pol   zum anderen Pol der Batterie.

 EMI2.1
 Movement guided in the vertical direction. A pull rod, which is connected to an arm of a lever mounted on the shoulder of the housing G, engages this pin. The free arm of the lever carries a running weight L, which is displaceable and lockable in order to be able to regulate the pressure with which the upper contact plate is pressed against the lower one. As can be seen from Fig. 4, the electric current goes from + pole in the upper plate A via the tips in the lower plate P and from there via-pole to the other pole of the battery.
 EMI2.2
 
1.

   Modification of the microphone according to Patent No. 22823, characterized by the arrangement of a large number of small rods with carbon or metal tips, embedded in one or more rows in a metal bar (K) connected to a battery pole and by a second bar (U), which is pressed with a screw (n) against the bar K, with a contact bar (i) attached below these rows of rods opposite the rods, which is connected to the second pole of the battery, so that a large number of contacts is formed .
