Description

Lautsprechermembrane Die vorliegende Erfindung bezieht sich auf eine Membrane für Lautsprecher o. dgl., welche infolge ihrer besonderen Herstellungsweise eine hohe Elastizität bei verhältnismäßig großer Härte aufweist.Loudspeaker diaphragm The present invention relates to a Membrane for speakers o. The like. Which due to their special manufacturing method has a high elasticity with relatively great hardness.

Das Wesen der Erfindung besteht darin, daß eine aus weichem Holz bestehende Scheibe, die sonst als Membrane nicht ver-\vendbar ist, durch Tränken mit verdünntem Fischleim und nachfolgendem Aufstrich von unverdünntem Fischleim, zu einer günstige Elastizität und große Härte aufweisenden Membrane gestaltet wird.The essence of the invention is that one made of soft wood Disc, which otherwise cannot be used as a membrane, by soaking it with diluted Isinglass and subsequent spread of undiluted isinglass, to a cheap one Elasticity and great hardness exhibiting membrane is designed.

Hiermit weist die Erfindung einen erheblichen technischen Fortschritt auf, der im gewerblichen Interesse von großer Bedeutung ist.The invention hereby represents a considerable technical advance which is of great importance in the commercial interest.

Die Herstellung der Membrane geht auf folgende Weise vor sich: Die aus weichem Holz- geschnittene Platte wird zunächst: mit verdünntem Fischleim von beiden Seiten her gut getränkt und dann zum Trocknen aufgestellt. Nach erfolgtem Trocknen wird die Platte mit einem weiteren Überzug aus dickflüssigem Fischleim versehen, worauf nach völligem Trocknen die Platte, im Gegensatz zu ihrer Schwapplichkeit im Rohzustande, außerordentlich hart wird und zu einer guten Elastizität gelangt.The production of the membrane is done in the following way: The Board cut from soft wood is first: with diluted isinglass from soaked well on both sides and then set up to dry. After the The plate is dried with another coating of viscous isinglass provided, whereupon, when completely dry, the plate, in contrast to its slackness in its raw state, becomes extremely hard and has good elasticity.

Sie ist dann zu Schwingungen fähig, die die Membrane ganz besonders für Lautsprecher o. dgl. geeignet machen.It is then capable of vibrations, especially those of the membrane Make it suitable for loudspeakers or the like.

Claims (1)

PATENTANSPRUCH: Lautsprechermembrane, dadurch gekennzeichnet, daß eine aus dünnem, weichem Holz bestehende Platte, die an sich infolge ihrer Schlappheit nicht zu verwenden wäre, durch Aufbringen und Tränken von oder in Fischleim in eine feste Membrane verwandelt wird, so daß der in der Membrane enthaltene Holzstoff nur als leichtes Traggerüst für die erhärtete Masse dient. PATENT CLAIM: Loudspeaker diaphragm, characterized in that a plate made of thin, soft wood, which could not be used due to its slackness, is transformed into a solid diaphragm by applying and soaking in isinglass, so that the one contained in the diaphragm Wood pulp serves only as a light supporting structure for the hardened mass.
