Die Figur 9 zeigt als Beispiel die Anordnung eines Schwingungserzeugers, der mit einem Resonator verbunden ist. Der Torsionsschwinger 7, der durch ein permanentes Gleichfeld 8 (siehe pfeilrichtung)und ein magnetisches Wechselfeld 9 zu mechanischen Torsionsschwingungen erregt wird, überträgt diese Schwingungen durch die bolzenförmigen Kopplungselemente 4 auf den Resonator 1. Die Schwingunbsrichtung ist durch Pfeile 10 angegeben. i3 n 3 -- Figur 10 zeigt die Schwingungser'-'egung eines-erfind'unge- r gemäss aufgebauten mechanischen Resonatorsystems mittels magnetostriktiver Längsschwinger 11 deren Bewegungsrichtung durch Pfeile 12 dargestellt ist. Die Resonatorplatten 1 sind durch drahtförmige Elemente 4 verbunden.As an example, FIG. 9 shows the arrangement of a vibration generator which is connected to a resonator. The torsional vibrator 7, which is excited to mechanical torsional vibrations by a permanent constant field 8 (see arrow direction) and an alternating magnetic field 9, transmits these vibrations through the bolt-shaped coupling elements 4 to the resonator 1. Die The direction of oscillation is indicated by arrows 10. i3 n 3 - FIG. 10 shows the vibration generation of an inventive r according to the mechanical resonator system constructed by means of magnetostrictive longitudinal oscillators 11, the direction of movement of which is shown by arrows 12. The resonator plates 1 are connected by wire-shaped elements 4.
