Die Verwendung von Holzfedern ist deshalb zu empfehlen, weil sie keine störenden   Geräusche   hervorrufen.

Die Wirkungsweise der   Vorrichtung   ist folgende : Die von den Nordpolen N ausgehenden Kraftlinien gehen gemeinsam durch den   Polsehuh     b und treten   in die Mitte des Ankers c ein, wo sich der magnetische Fluss teilt. Eine Hälfte geht durch den oberen, die andere durch den unteren Teil des Ankers

    PATENT-ANSPRÜCHE:  
1. Magnetsystem, insbesondere für Lautsprecher, bei dem ein mit der Lautsprechermembran verbundener Anker, der im magnetischen Kreis von permanenten Magneten liegt, von den Sprechstromspulen umgeben und so angeordnet ist, dass er in der Richtung der ihn durchsetzenden magnetischen Kraftlinien schwingen kann, dadurch gekennzeichnet, dass von einer Gruppe gleichnamiger Pole (N) der

 of the pole shoes el, Fs xial, these bolts being connected to wooden springs i, which are attached to the permanent magnets, by means of the screw nuts h 'and g'. The use of wooden springs is recommended because they do not cause any disturbing noises. The screw bolt g is connected to the membrane, while the bolt h, by being arranged in pairs, the anchor

 halves k attached symmetrically to the armature center, tightly enclosing the armature and their winding is arranged so that the field generated by them falls in the direction of the armature axis.



   The anchor can be adjusted using the nuts h 'and g'.
 EMI1.4
 
The mode of operation of the device is as follows: The lines of force emanating from the north poles N go together through the pole shoe b and enter the center of the armature c, where the magnetic flux divides. One half goes through the top and the other half through the bottom of the anchor
 EMI1.5
 Ankers of the same name and - provided that the air gaps are the same size - are magnetically excited to the same extent. The anchor therefore remains at rest. If, however, current flows through the coil k, a field is superimposed on the armature fields, which reinforces one end pole surface on the other

   The course of the lines of force of the permanent field is indicated by dash-dotted lines.



    PATENT CLAIMS:
1. Magnetic system, in particular for loudspeakers, in which an armature connected to the loudspeaker membrane and located in the magnetic circuit of permanent magnets, surrounded by the voice current coils and arranged so that it can vibrate in the direction of the magnetic lines of force penetrating it, that from a group of poles with the same name (N) the
