Es ist eine Stimmgabelanordnung als Gangordnerschwinger für eine elektrische Uhr bekannt, bei"welcher an den freien Zinkenenden seitlich permanente Topfmagnete angeordnet sind, in die fest angeordnete Spulen hineinragen, die im Eingangskreis und im Ausgangskreis einer Transistorschaltung liegen. Diese Anordnung hat einen verhältnis-■ mäßig großen Platzbedarf. Außerdem ist die schwingende Masse verhältnismäßig groß.It is a tuning fork arrangement as an aisle folder oscillator known for an electric clock, "which at the free prong ends are arranged laterally permanent pot magnets, protrude into the fixed coils that lie in the input circuit and in the output circuit of a transistor circuit. This arrangement has a ratio ■ moderately large space requirement. In addition, the vibrating mass is relatively large.
Der Erfindung liegt die Aufgabe zugrunde, eine Stimmgabel der eingangs genannten Art zu schaffen·* die einen vergleichsweise geringen Platzbedarf hat und bei welcher die schwingende Masse verhältnismäßig klein ist. Dies wird erfindungsgemäß dadurch erreicht, daß die Spulen in Verlängerung der Stimmgabelzinken an diesen befestigt sind und daß die Außenwand der fest angeordneten, topfförmigen Permanentmagnet anordnung mit einem Schlitz zur Durchführung der Stimmgabelzinke versehen ist. Vorzugsweise ist jede Spule an einem Zinkenende angeordnet, und es ist jeder Spule eine feststehende, topfförmige Permanentmagnetanordnung zugeordnet. Die Zuleitungen zu den an den Enden der Stimmgabelzinken angeordneten Spulen verlaufen zweckmäßig über die Befestigungsstelle am Stimmgabelsteg und über die Stimmgabelarme. The invention is based on the object of creating a tuning fork of the type mentioned at the beginning has little space requirement and in which the vibrating mass is relatively small. This is according to the invention achieved in that the coils are attached to the prongs of the tuning fork and that the outer wall of the fixed, cup-shaped permanent magnet arrangement is provided with a slot to carry out the tuning fork prong. Preferably each coil is on one Arranged prong end, and each coil is assigned a fixed, cup-shaped permanent magnet arrangement. The feed lines to the coils arranged at the ends of the tuning fork prongs run expediently over the fastening point on the tuning fork web and over the tuning fork arms.

Die Erfindung ist im folgenden an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung in einem Längsschnitt dargestellt ist.The invention is explained in more detail below using an exemplary embodiment that is shown in the drawing in a Longitudinal section is shown.
70 ist eine Stimmgabel mit den Zinken 70a und 70b. Der Stegteil 70c der Stimmgabel 70 ist über ein mit diesem in Verbindung stehendes Teil an einer Grundplatte oder dergl. befestigt. An den Zinken 70a und 70b sind in deren Verlängerung Spulen 72 und 73 so angeordnet, daß ihre Mittelachsen zusammenfallen und in Richtung der Schwingungsbewegung der Zinken 70a und 70b verlaufen. Die Spulen 72 und 73 liegen im Eingangskreis und im Ausgangskreis einer nicht dargestellten elektronischen Verstärkerschaltung, vorzugsweise einer Halbleiter-Verstärkerschaltung. Die Verbindung zwischen der Verstärkerschaltung und den Spulen 72 und 73 erfolgt über Leitungen 78, die über die Stimmgabelzinken 70a und 70b, über die Befestigungsstelle der Stimmgabel 70 zu dem Klemmbrett 77 verlaufen.70 is a tuning fork with prongs 70a and 70b. The web part 70c of the tuning fork 70 is via a with this related part attached to a base plate or the like. On the prongs 70a and 70b are in their Extension coils 72 and 73 are arranged so that their central axes coincide and extend in the direction of the vibratory movement of the prongs 70a and 70b. The coils 72 and 73 are in the input circuit and in the output circuit of an electronic amplifier circuit, not shown, preferably a semiconductor amplifier circuit. The connection between the amplifier circuit and the coils 72 and 73 takes place via lines 78, which over the tuning fork prongs 70a and 70b, over the fastening point of the tuning fork 70 to the clipboard 77 run.
Die Spulen 72 und 73 befinden sich in zwei permanenten Topfmagneten, die aus einem Permanentmagneten 71a bzw. 71b sowie einem gehäuseartigen Hückschlußteil 77a bzw. 77b bestehen, die an Trägern 75a und 75b befestigt sind. In derThe coils 72 and 73 are located in two permanent pot magnets, which consist of a permanent magnet 71a and 71a, respectively. 71b and a housing-like back yoke part 77a or 77b exist, which are attached to beams 75a and 75b. In the

topfförmigen Außenwand jeder Magnetanordnung ist ein Schlitz vorgesehen, durch den eine Stimmgabelzinke 70a bzw. 70b hindurchragt .cup-shaped outer wall of each magnet assembly is a slot provided through which a tuning fork prong 70a or 70b protrudes.
Wie die Zeichnung ohne weiteres erkennen läßt, läßt sich die erfindungsgemäße Stimmgabel mit verhältnismäßig geringer Breite herstellen.As the drawing can be seen without further ado, the tuning fork according to the invention can be relatively produce a narrow width.
