 EMI2.1 
 



   Um zwischen den Kontakten 3 der schwingenden Stäbe 2 grössere Entfernung zu halten bzw. einen grösseren   Schwingungsau88chlag   zu erzielen, kann, wie in Fig. 4 : dargestellt, vor dem freien Ende jedes Stabes 2, in eine Höhlung 8 desselben lose eingreifend, ein Hebel 9 angeordnet sein, dessen langer Arm zwischen den Kontakten 3 schwingt. 



   PATENT-ANSPRÜCHE : 
1.   Einrichtung zur schriftlichen Aufzeichnung von Tönen oder Sprachlauten bzw. Verbindungen   derselben, dadurch gekennzeichnet, dass unmittelbar hinter einer durch die Wellen des wiederzugebenden Tones oder Lautes in bekannter Weise erregten, schwingenden Membran Stäbe angeordnet sind, welche am einen Ende in geeigneter Weise festgehalten sind, und von denen jeder mit seinem freien Ende durch die von der Membran übertragenen Wellen nur bei der ihm 
 EMI2.2 
 gegenüberliegenden Kontakten Stromschluss in der Leitung eines das betreffende Wiedergabezeichen auslösenden Elektromagneten herstellen.

 EMI2.1
 



   In order to keep a greater distance between the contacts 3 of the vibrating rods 2 or to achieve a greater vibration shock, a lever 9 can, as shown in FIG. 4: in front of the free end of each rod 2, loosely engaging in a cavity 8 of the same be arranged whose long arm swings between the contacts 3.



   PATENT CLAIMS:
1. Device for the written recording of tones or speech sounds or connections thereof, characterized in that immediately behind a vibrating membrane which is excited in a known manner by the waves of the tone or sound to be reproduced, rods are arranged which are held in a suitable manner at one end , and each of which with its free end through the waves transmitted by the membrane only at him
 EMI2.2
 opposite contacts establish a current connection in the line of an electromagnet that triggers the relevant reproduction mark.

Claims

2. Device according to claim 1 for recording speech sounds or words, characterized in that the rods for each individual sound, depending on its composition, are arranged from a fundamental assigned, very specific overtones in groups, each of which has a composition that is unique to the respective sound of rods which are connected in series with their contacts and which all have to vibrate in order to trigger the relevant character.

3. Device according to claim 1, characterized in that at the free end of each rod (2), loosely engaging the same in a cavity, a lever (9) is provided, the long arm of which swings between the two contacts (3), whereby a larger one Oscillation amplitude is achieved.
