Description

Vorrichtung zum Aufzeichnen von Tönen Gegenstand der Erfindung ist eine weitere Ausgestaltung der in Patent 6.96558 beschriebenen Vorrichtung zum Aufzeichnen von Tönen, @enmthaltend -ein Idas Lichtsteuerorganb ewegendes elastisches Band bnv. einen Draht, dessen eines Ende an einem Träger ortsfest ist und das in der Ruhelage gerade- oder annähernd geradegestreckt und dessen anderes Ende an der Schwingfläche einer Membran so befestigt ist, daß die Richtungen der Durchbiegung der Membran und des Biandes zueinaiid'er senkrecht liegen. Dieses mit der Membran verbundene Band hat man bisher fastausschließlich aus Metall hergestellt.Apparatus for recording sounds is the subject of the invention a further embodiment of the recording apparatus described in patent 6.96558 of tones, @enmthaltend -an Idas light control organ moving elastic band bnv. a wire, one end of which is stationary on a carrier and that in the rest position stretched straight or almost straight and its other end on the oscillating surface a membrane is attached so that the directions of deflection of the membrane and the band are perpendicular to each other. This connected to the membrane Up to now, bands have been made almost exclusively from metal.

Es wurde nun gefunden,. daß sich Glas oder glasähnliche Kunststoffe für die Herstellung des Bandes @avßerordentlich gut eignen. Zweckmäßigerweise wird ein röhrenförmiges Glasband verwendet. Gibt man zudem dieser Röhre ovalen oder rechteckigen Querschnitt, so erhält man auf diese Weise wie bei einem Metallband seine ganz bestimmte Durchbiegungsrichtung. Die Vorteile der Verwendung dieses neuen Werkstoffes bestehen hauptsächlich in der Korro-sionsbeständigkeit, in der Elastizität, dem geringen spezifischen Gewicht und in der Unabhängigkeit von klimatischen Einflüssen, wie z. B. Temperatur und Luftfeuchtigleeit.It has now been found. that glass or glass-like plastics extremely well suited for the production of the tape @ a. Appropriately is a tubular glass ribbon is used. You also give this tube oval or rectangular Cross-section, in this way you get a very specific one, just like with a metal band Deflection direction. The advantages of using this new material exist mainly in the corrosion resistance, in the elasticity, the low specific weight and independence from climatic influences, such as z. B. Temperature and humidity.
