Description

Es ist bekannt, der angetriebenen Kante von Lautsprecheroaembranen, die aus mehreren gewölbten Teilen zusammengesetzt und am Rande eingespannt sind, dadurch eine Führung zu geben, daß man diese durch ein quer zu ihr verlaufendes, nachgiebiges Band, einen Faden o. dgl. hält. Eine derartige nur an einer Stelle befindliche Führung hat aber den Nachteil, daß verhältnismäßig lang ausgestreckte oder sehr schwach gehaltene Antriebskanten nicht einwandfrei im Luftspalt des Magnetfeldes geführt werden können.It is known the driven edge of loudspeaker diaphragms that are made up of several arched parts are assembled and clamped at the edge, thereby a To give guidance so that this can be carried out by a flexible band running across it, holds a thread or the like. However, such a guide, which is only located at one point, has the disadvantage that drive edges are relatively long or very weakly held cannot be guided properly in the air gap of the magnetic field.

Es hat sich gezeigt, daß diese Axt der Führung, die zumal bei großflächigen Membranen erforderlich ist, wesentlich dadurch verbessert werden kann, daß man die Fäden nicht nur an einem Punkte, sondern an mehreren entlang der bewegten Kante verteilten Punkten anbringt. Es empfiehlt sich dabei außerdem, an jeder dieser Halterungsstellen mehrere parallele Fäden derart nebeneinander anzubringen, daß die durch sie bestimmte Ebene senkrecht zur Antriebskante liegt.It has been shown that this ax of leadership, especially with large membranes is required, can be significantly improved by the fact that the threads not only at one point, but at several attaches points distributed along the moving edge. It is also advisable to use each of these mounting points to attach several parallel threads next to each other in such a way that the determined by them Plane is perpendicular to the drive edge.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Membran m wird an mehreren entlang ihrer Antriebskante gelegenen Punkten durch nachgiebige Fäden/ gehalten. An jeder dieser Stellen befinden sich zwei parallele Fäien, wobei die Ebene, in der sie liegen, zur Antriebskante k senkrecht steht. Die Fäden/ sind seitlich an einem feststehenden Teil g, z. B. dem Gehäuse des Lautsprechers, befestigt.An exemplary embodiment of the invention is shown in the drawing. The membrane m is held in place by flexible threads / at several points along its drive edge. At each of these points there are two parallel lines, the plane in which they lie being perpendicular to the drive edge k. The threads / are on the side of a fixed part g, z. B. the housing of the speaker attached.

Die beschriebene Membranhalterung ist sowohl für einfach als auch für mehrfach gewölbte Membranen verwendbar, wobei es gleichgültig ist, auf welche Art die Antriebskante erregt wird. Auch bei der Vierwendung der Vorrichtung als Mikrophon ist die Erfindung benutzbar.The membrane holder described is for both single and multi-arched Membranes can be used, it does not matter in which way the drive edge is excited. Even with the four-turn the device can be used as a microphone.
