Description
Die Erfindung betrifft einen 'elektrodynamischen Lautsprecher, der auf einen großen Frequenzbereich ansprechen soll. Zu diesem Zwecke werden als Membran in an sich 5.bekannter Weise mehrere konische Flächen verschiedener Abmessungen verwendet, die elastisch miteinander verbunden sind und durch, eine Spule angetrieben werden, die in einer Ringnut 'eines von den Wechselströmen ίο gest6uerten magnetischen Kreises angeordnet sind.The invention relates to an 'electrodynamic loudspeaker on a large Frequency range should respond. For this purpose, several conical surfaces are used as a membrane in a manner known per se different dimensions are used, which are elastically connected to each other and driven by a coil, which is in an annular groove 'one of the alternating currents ίο controlled magnetic circuit arranged are.
Ein wesentliches Merkmal der Erfindung beruht darin, daß die kleinere kegelförmige Membran in ihrer Außenkante mit der größeren kegelförmigen Membran auf einer Kreisr linie elastisch verbunden ist, die etwa in der Mitte des Umfanges der größeren kegelförmigen Membran liegt.An essential feature of the invention is that the smaller conical Membrane in its outer edge with the larger conical membrane on a circle line is elastically connected, which is approximately in the middle of the circumference of the larger conical Membrane lies.
Ein Aueführungsbeispiel der Erfindung ist ao auf der Zeichnung in zwei Abbildungen dargestellt. An exemplary embodiment of the invention is shown in the drawing in two figures.
Zwischen den Polstücken N und Q (Abb. 1) ist eine Kreisnut vorgesehen. Die in dieser Nut angeordnete Spule I? ist fest mit 'einer kegelförmigen Membran C1 verbunden, während eine dazu konzentrische zweite kegelförmige Membran C2 nachgiebig einerseits mit C1 und anderseits mit dem Gehäuse verbunden ist.A circular groove is provided between the pole pieces N and Q (Fig. 1). The coil I? is firmly connected to a conical membrane C 1 , while a second conical membrane C 2 concentric thereto is flexibly connected on the one hand to C 1 and on the other hand to the housing.
Abb. 2 zeigt den Aufhängungsteil. Es wird hier die bewegliche Spule Z? der Abb·. 1 auf den mittleren kreisförmigen Teilß der Abb. 2 aufgeklebt. Die Aufhängung dieser Spule (Abb. 1) und damit der mit ihr fest verbundenen kegelförmigen Membran C1 der Abb. 1 erfolgt einerseits bei S1 auf einem Kreis, der etwa in der Mitte der kegelförmigen Membran C2 liegt, und anderseits auf der kleinen Basis der beiden Membranen durch Stege X (Abb. 2). Der Ring δ in dieser Abbildung trägt die kleine Basis der kegelförmigen Membran C2 und ist durch die Stege O aufgehängt. Die kegelförmige Membran C2 ist anderseits tan ihrer großen Basis bei S2 aufgehängt. Fig. 2 shows the suspension part. It will be the moving coil Z? the fig. 1 glued to the central circular part of fig. The suspension of this coil (Fig. 1) and thus the conical membrane C 1 of Fig. 1 firmly connected to it takes place on the one hand at S 1 on a circle which lies approximately in the middle of the conical membrane C 2 , and on the other hand on the small one Base of the two membranes through webs X (Fig. 2). The ring δ in this figure carries the small base of the conical membrane C 2 and is suspended by the webs O. On the other hand, the conical membrane C 2 is suspended from its large base at S 2.
Durch passende Bemessung der Befestigungsorgane X, die die beiden Membranen verbinden, kann man erreichen, daß die große kegelförmige Membran C2 in der Hauptsache nur durch die tiefen Frequenzen betätigt wird und bei höheren Frequenzen unbeeinflußt bleibt. Hierdurch erhält man einen Lautsprecher mit zwei Ansprechbereichen.By appropriately dimensioning the fastening elements X which connect the two membranes, one can achieve that the large conical membrane C 2 is mainly actuated only by the low frequencies and remains unaffected at higher frequencies. This results in a loudspeaker with two response areas.
