Description

Verfahren zur Herstellung der zweckmäßig aus einer auf eine dünne Gummihaut aufgeklebten Metallfolie bestehenden Membran eines elektrostatischen Lautsprechers Die Membran eines elektrostatischen Lautsprechers wird zweckmäßig aus- einer dünnen Gummihaut hergestellt, weil die geringe Steifigkeit dieses Stoffes eine sehr tiefe Resonanzlage bei der Eigenschwingung zur Folge hat.Process for the preparation of the expedient from one to one thin Rubber skin glued on metal foil existing membrane of an electrostatic loudspeaker The membrane of an electrostatic loudspeaker is expediently made from a thin one Rubber skin is made because the low stiffness of this material is very deep Resonance position in the natural oscillation.

Diese geringe Steifigkeit wird aber mehr oder weniger aufgehoben, wenn zum Aufkleben der Metallbelegung auf die Gummihaut ein Klebstoff benutzt wird, der verharzt und dabei steif wird.This low stiffness is more or less canceled out, if an adhesive is used to glue the metal covering onto the rubber skin, which becomes resinous and stiff in the process.

Nach der Erfindung wird nun als Verbindungsmittel zwischen der Metallfolie und der Gummihaut ein Pflanzenöl, z. B. Rizinusöl, verwendet, das den Gummi nicht angreift und wegen des guten Luftabschlusses fast gar nicht verharzt und steif wird.According to the invention is now used as a connecting means between the metal foil and the rubber skin a vegetable oil, e.g. B. castor oil, which does not affect the gum attacks and due to the good air seal is almost not gummy and stiff.

PATENTANSPRUCH: Verfahren zur Herstellung der zweckmäßig aus einer auf eine dünne Gummihaut aufgeklebten Metallfolie bestehenden Membran eines elektrostatischen Lautsprechers, dadurch gekennzeichnet, daß als Verbindungsmittel zwischen Metallfolie und Gummihaut ein bei gutem Luftabschluß wenig verharzendes Pflanzenöl, z. B. Rizinusöl, benutzt wird.PATENT CLAIM: Process for the production of the expedient from one on a thin rubber skin glued metal foil consisting of an electrostatic membrane Loudspeaker, characterized in that as a connecting means between metal foil and rubber skin, a vegetable oil that does not resinify much if the air is well sealed, e.g. B. castor oil, is used.
