Description

Die Erfindung bezieht sich auf eine Haltevorrichtung für den Anker von vierpoligen Lautsprechern, der im Spuleninneren nachgiebig gelagert ist.The invention relates to a holding device for the armature of four-pole Speakers, which is resiliently mounted inside the coil.

Es ist bereits bekannt, den Spulenkörper aus Metallblech herzustellen und den Anker nachgiebig mittels Gelenke oder am Anker angelöteter nachgiebiger Blechstreifen zu halten. Bei derartigen Anordnungen sind zahlreiche Handgriffe erforderlich, um das System fertigzustellen.It is already known to manufacture the coil body from sheet metal and the armature to be held resiliently by means of joints or resilient sheet metal strips soldered to the anchor. With such arrangements, numerous manipulations are required to the system to finish.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß der Anker von aus der Spulkörperwandung selbst heraus-According to the invention, these disadvantages are avoided in that the anchor of out of the bobbin wall itself-

gebogenen elastischen Zunge'n getragen wird, die auch die federnde Rückstellkraft für den Anker liefern, so daß auf diese Weise eine äußerst einfache Herstellung des Systems ermöglicht ist.curved elastic tongue is worn, which also provides the resilient restoring force for the Deliver anchors, so that in this way an extremely simple manufacture of the system is possible is.

so Die Abbildung veranschaulicht Ausführungsbeispiele des Erfindungsgegenstandes, und zwar zeigt die Fig. 1 den Lautsprecher im Schnitt; Fig. 2 und 3 zeigen Einzelteile davon; die Fig#| und^oi beziehen sich auf Einzelheiten einer etwas abgeänderten Ausführungsform. so The figure illustrates exemplary embodiments of the subject matter of the invention, namely, Fig. 1 shows the loudspeaker in section; Fig. 2 and 3 show items of that; the figure # | and ^ oi refer to Details of a slightly modified embodiment.

Der Lautsprecher gemäß Fig. 1 zeigt eine Konusmembran 10, die von einem Stift 11 durch Vermittlung eines Ankers 12 betätigt wird. Dieser Anker sitzt an Ansätzen 13 undThe loudspeaker according to FIG. 1 shows a conical diaphragm 10 which is supported by a pin 11 is actuated by the intermediary of an armature 12. This anchor sits on lugs 13 and

14 des Spulengehäuses, das aus den Teilen14 of the coil housing, which is made up of the parts

15 und 16 besteht, die aus elastischem, nichtmagnetischem Metall von hohem Widerstand hergestellt sind. Um dieses Spulengehäuse sitzt eine Spule 17, die die Sprechströme aufnimmt oder erzeugt, während ein Dauermagnet 18 mit den Polstücken 19 bis 22 das magnetische Feld erzeugt, in dem sich der Anker bewegt.15 and 16, which are made of elastic, non-magnetic metal of high resistance are made. A coil 17 is seated around this coil housing and absorbs the speech currents or generated while a permanent magnet 18 with the pole pieces 19 to 22 the generated magnetic field in which the armature moves.

Fig. 2 zeigt das Spulengehäuse mit den Polstücken zusammengebaut, Fig. 3 auseinandergezogen. Fig. 2 shows the coil housing with the Pole pieces assembled, Fig. 3 pulled apart.

Die Teile 15 und 16 sind mit Augen versehen, die in eine Verriegelungsstellung umgebogen werden, wenn die Einzelteile zusammengesetzt sind. Dadurch werden diese miteinander und mit den Endplatten 23 und 24 verbunden. Zwischen diesen Endplatten und den Gehäuseteilen 15 und 16, in denen die Polstücke durch Schrauben 25 befestigt sind, ist Raum für die Polstücke gelassen. Der Anker 12 ist ein durchgehendes Metallstück, ohne irgendwelche Nuten oder Unterbrechungen, während die Ansätze 13 und 14 einfach einen Teil des Spulengehäuses bilden.Parts 15 and 16 are provided with eyes, which are bent into a locking position when the individual parts are assembled are. This connects them to one another and to the end plates 23 and 24. Between these end plates and the housing parts 15 and 16, in which the pole pieces are fastened by screws 25, space is left for the pole pieces. The anchor 12 is a continuous piece of metal, without any grooves or interruptions, while lugs 13 and 14 are simple form part of the bobbin case.

Bei der Ausführungsform gemäß Fig. 4 und S besteht das Gehäuse aus einem einzigen Metallstück 26, das mit Flanschen 27 und 2S für die Polstücke und einem Teil 29 versehen ist, an dem der Anker 12 befestigt isti Dieser Teil 29 bildet die Federungskraft und den Drehpunkt für den Anker, und es ist diese Konstruktion etwas einfacher als die gemäß Fig. i, 2 und 3.In the embodiment according to FIGS. 4 and 5, the housing consists of a single one Metal piece 26 provided with flanges 27 and 2S for the pole pieces and a part 29 is to which the armature 12 is attached. This part 29 forms the spring force and the Pivot point for the anchor, and this construction is a little simpler than the one according to Figs. I, 2 and 3.

Der Lautsprecher gemäß der Erfindung hat den Vorteil, daß der Anker in sehr einfacher Weise eingebaut und zentriert ist.The loudspeaker according to the invention has the advantage that the anchor is very simple Way is built in and centered.
