Description

Es sind bereits an dem geraden Ende tangential angetriebene, kurvenförmig gebogene Blattmembranen bekannt, deren eines Ende fest eingespannt ist. Der Antrieb erfolgt im wesentlichen punktförmig in Richtung der Blattebene des freien Membranendes. Hierbei sucht das nachgiebige Membranmaterial aus·- zuweichen, so daß die Schwingungen mit schlechtem Wirkungsgrad auf die Membran übertragen werden. Die freien Membrankanten neigen zum Flattern. Dieser Nachteil wird durch die im folgenden beschriebene Anordnung beseitigt. Hierbei ist die verhältnis- - mäßig lange Antriebsnadel über einen großen Teil ihrer Länge fest mit dey Blattebene der Membran verbunden; das freie Membranende wird dadurch versteift, und die oben angedeuteten Mangel werden beseitigt.There are already at the straight end driven tangentially, curved in a curve Known sheet membranes, one end of which is firmly clamped. The drive takes place in essentially punctiform in the direction of the plane of the sheet of the free end of the membrane. Here seeks the flexible membrane material from · - to give way, so that the vibrations with poor efficiency are transferred to the membrane. The free membrane edges tend to flutter. This disadvantage is caused by the arrangement described below eliminated. Here, the relatively long drive needle is over a large one Part of its length firmly attached to the leaf plane of the membrane; the free end of the membrane is thereby stiffened, and the deficiencies indicated above are eliminated.

Die Neuerung ist für akustische Empfänger und Geber, insbesondere für Lautsprecher, aber auch für Sprechmaschinen verwendbar. Auf der beiliegenden Zeichnung ist eine beispielsweise Ausführung dargestellt. Es zeigt Abb. ι die Membran und die Antriebsnadel as in unmontiertem Zustande,The innovation is for acoustic receivers and transmitters, especially for loudspeakers, but can also be used for speaking machines. On the accompanying drawing is an example Execution shown. It shows Fig. Ι the membrane and the drive needle as in unassembled condition,

Abb. 2 die Membran mit Antriebsnadel und Magnetsystem zusammenmontiert.Fig. 2 the membrane with the drive needle and magnet system assembled.

Die Membran α ist mit einer Führungsrinne b versehen, in welcher die Nadel c, die mit dem Magnetsystem d verbunden ist, befestigt wird. Durch das Magnetsystem d wird der Nadelträger in Schwingungen versetzt, die sich durch die Nadel c auf die von dieser getragene Membran α und auf die umgebende Luft übertragen.The membrane α is provided with a guide groove b in which the needle c, which is connected to the magnet system d , is attached. The needle carrier is set in vibrations by the magnet system d , which are transmitted through the needle c to the membrane α carried by the latter and to the surrounding air.
