Description

Die Erfindung bezieht sich auf eine weitere Ausbildung und Verbesserung des Gegenstandes des Patents 876 500. Nach diesem Patent erstrecken' sich bei elektromagnetischen Abtastern für die Saitenschwingungen von Musikinstrumenten mit U-förmigen, längs parallel zu den Saiten laufenden Polschuhen diese Polschuhe über die Spulenwicke= -Jung hinweg.The invention relates to a further development and improvement of the subject matter of patent 876,500. According to this patent, in electromagnetic Samplers for the string vibrations of musical instruments with U-shaped, lengthways pole pieces running parallel to the strings, these pole pieces over the coil winding = -Go away boy.

Es gibt Musikinstrumente mit besonders breiter Saitenlage, d. h. nicht nur mit sechs Saiten, wie bei den Gitarren, sondern mit einer erheblich größeren Saitenzahl, z. B. mit q:2 Saiten, wie bei einer Zitherart.There are musical instruments with a particularly wide string position, i. H. not only with six strings, as with the guitars, but with a considerably larger one Number of strings, e.g. B. with q: 2 strings, like a zither kind.

Um nun die gleichen Wirkungen wie beispielsweise bei Gitarrenabtastern gemäß dem Patent 876.5oo zu erreichen, ist es notwendig, hierzu mehrere Magnetsysteme gleicher Art. in :einer Linie hintereinander anzuordnen, um ein homogenes Kraftfeld. für sämtliche Saiten zu erzielen. Dies wird erfindungsgemäß dadurch erreicht, daß die Polschuhe benachbarter Magnete sich über die Spulenwickelung hinweg erstrecken und aneinanderstoßen oder daß ein, gemeinsamer Polschuh sich über sämtliche Magnete nebst ihren Wickelungen erstreckt. Hierbei sind die Spulen der hintereinander angeordneten. Magnete miteinander elektrisch verbunden und die Lücken zwischen den einzelnen Spulen durch die Polschuhe überbrückt.To now have the same effects as, for example, with guitar scanners According to the patent 876,5oo, it is necessary to use several magnet systems of the same kind. in: to be arranged in a line one behind the other to create a homogeneous force field. for all strings. This is achieved according to the invention in that the pole pieces of adjacent magnets extend over the coil winding and butt against each other or that a common pole piece extends over all magnets along with their windings extends. Here, the coils are arranged one behind the other. Magnets are electrically connected to each other and the gaps between the individual coils bridged by the pole pieces.

Der Erfindungsgegenstand ist in beispielsweisen Ausführungsformen in der Zeichnung dargestellt, und zwar zeigt Fig. i eine Seitenansicht eines Abtasters, bei dem mehrere in einer Linie hintereinander angeordnete-Magnetsysteme für ein breites Saitenfeld zusammengestellt sind, Fig. 2 eine andere Ausführung nach Fig. i mit einem einzigen, alle Magnetsysteme überdeckenden Polschuh, Fig. 3 eine Ansicht auf eine Zither mit Abtaster aus mehreren in einer Linie hintereinander unter den Freisaiten angeordneten. Magnetsystemen, Fig. q. eine weitere Zither mit einem oberhalb sämtlicher Saiten angeordneten Abtaster mit mehreren in einer Linie hintereinanderliegenden Magnetsystemen.The subject matter of the invention is in exemplary embodiments shown in the drawing, namely Fig. i shows a side view of a scanner, in which several magnet systems arranged one behind the other in a line for one wide string field are put together, Fig. 2 shows another embodiment according to Fig. i with a single pole piece covering all magnet systems, FIG. 3 is a view on a zither with a pickup consisting of several in a line one behind the other under the Open strings arranged. Magnet systems, Fig. Q. another zither with one above all strings arranged scanner with several in a line one behind the other Magnet systems.

Nach der Ausführung gemäß Fig. i sind für ein breites Saitenfeld mehrere in einer Linie hintereinander angeordnete Magnete mit Spulen 17, 18,. i9, 2o von zweckmäßiger Einzellänge vorgesehen. Diese sind miteinander elektrisch verbunden. Über jeden Magnet und seiner Spule befindet sich ein Polschuh 21, der sich über die Spulenwickelung hinaus erstreckt. Die Polschuhe 21 aller benachbarten Magnete stoßen einander an. Es entsteht hierdurch in der Gesamtausdehnung aller vier Magnetsysteme ein homogenes Kraftfeld. Wie Fig. 2 zeigt, findet an Stelle einzelner Polschuhe 21 bei der hierdurch dargestellten Ausführung ein einziger Polschuh 22 Anwendung, der alle Spulen überbrückt und der einen einzigen Körper bildet. Auch hier stehen: ,die Spulen miteinander in elektrischer Verbindung. Es entsteht über die ganze Länge ein gleichmäßiges magnetisches Kraftfeld.According to the embodiment according to FIG. I, there are several for a wide string field magnets with coils 17, 18, arranged one behind the other in a line. i9, 2o of appropriate individual length provided. These are electrically connected to one another. There is a pole piece 21 over each magnet and its coil extends beyond the coil winding. The pole shoes 21 of all neighboring magnets bump into each other. This results in the total expansion of all four magnet systems a homogeneous force field. As Fig. 2 shows, takes place in place of individual pole pieces 21 in the embodiment shown here, a single pole piece 22 application, which bridges all coils and which forms a single body. Also here are: , the coils in electrical communication with one another. It arises over the entire length a uniform magnetic force field.

Bei der Zither nach Fig. 3. ist ein Abtaster i und ein weiterer Abtaster 2,4 vorgesehen, der aus einzelnen in einer Linie hintereinander unter den Freisaiten angeordneten Magnetsystemen besteht, und im Sinn des Vorgesagten verbunden. Abtaster i und 24 sind elektrisch miteinander verbunden. Der Abtaster i befindet sich unter den Melodiesaiten als harmonischer Abschluß ,des Zithergriffbrettes 25, und der gemäß Fig. i oder :2 ausgebildete Abtaster aq. liegt unter den Freisaiten, hier in. Höhe der Schallochmittedeshalb gezeichnet, weil daselbst die klanglich günstigste Amplitude entsteht. Die Ausführung kann auch so getroffen. sein, daß beide Abtaster i und 24 oder einer von beiden über den Saiten angeordnet werden und daß der Tonabnehmer 24 vom Schalloch weg an eine andere Stelle, z. B. in Höhe .des Abtasters i, verlegt wird. In diesem Fall kann auch auf die Verwendung getrennter Abtaster verzichtet und ein durchgehend unter allen oder über allen Saiten angebrachter Abtaster mit den erfindungsgemäßen Merkmalen Verwendung finden. Dies kann nicht nur bei der Zither, wie in Fig. 4 mit &-m Abtaster 26 über den Saiten gezeigt, sondern bei allen Musikinstrumenten mit breiter Saitenlage, wie z. B. beim Klavier oder Cembalo, durchgeführt werden.In the zither according to FIG. 3, there is a scanner i and another scanner 2.4 provided, the one behind the other in a line under the open strings arranged magnet systems, and connected in the sense of the above. Scanner i and 24 are electrically connected to each other. The scanner i is located below the melody strings as a harmonic conclusion, the zither fingerboard 25, and the according to Fig. i or: 2 formed scanner aq. is under the free strings, here in. Height of the sound hole center is drawn because it is the most favorable in terms of sound there Amplitude arises. The execution can also be taken like this. be that both scanners i and 24 or one of both can be placed above the strings and that the pickup 24 away from the sound hole to another location, e.g. B. in the amount of .des scanner i, relocated will. In this case, the use of separate scanners can also be dispensed with and a pickup attached continuously under or over all strings the features according to the invention find use. This can not only be done with the zither, as shown in Fig. 4 with & -m pickup 26 above the strings, but with all Musical instruments with wide strings, such as B. performed on the piano or harpsichord will.
