Description
Dynamisches Mikrofon oder Lautsprecher Bei den bekannten Bändchenmikrofonen wird ein dünnes, aus leitendem Metall bestehendes Bändchen als Leiter ?wischen den Polschuhen eines Magneten angeordnet. Das Bändchen hat die Form eines schmalen Rechtecks, ist in der Querrichtung meistens geriffelt und an seinen Enden ein.-gespannt.Dynamic microphone or loudspeaker With the well-known ribbon microphones a thin ribbon made of conductive metal acts as a conductor? wipe the Arranged pole pieces of a magnet. The ribbon has the shape of a narrow rectangle, is mostly corrugated in the transverse direction and clamped at its ends.
Bei diesen Bändchenmikrofonen treten mehrere entscheidende Nachteile auf. Trotzdem die Bändchen aus sehr dünnem Material von nur 3/iooo bis s/iooo mm bestehen, ist die Eigenresonanz der Aufhängung ziemlich hoch. Außerdem neigen solche Bändchen bei Überlastung dazu, überdehnt zu werden und werden dadurch unbrauchbar.There are several key disadvantages with these ribbon microphones on. Nevertheless the ribbon made of very thin material of only 3 / iooo to 3 / iooo mm exist, the self-resonance of the suspension is quite high. In addition, they tend to When overloaded, the tendons tend to be overstretched and thus become unusable.
Eine Überdehnung tritt sogar bereits durch das eigene Gewicht auf, besonders, wenn das Bändchen längere Zeit in horizontaler Lage belassen wird. Gegenstand der Erfindung ist ein Bändchen, welches die geschilderten Nachteile nicht aufweist.Overstretching even occurs due to your own weight, especially if the ribbon is left in a horizontal position for a long time. object The invention is a ribbon which does not have the disadvantages outlined.
Erfindungsgemäß wird dieses dadurch erreicht, daß ein Bändchen nicht in der Form eines schmalen Rechtecks gestaltet wird, sondern in der Draufsicht die Form eines Winkels erhält.According to the invention this is achieved in that a ribbon is not is designed in the shape of a narrow rectangle, but in the plan view the The shape of an angle.
Das Bändchen kann in Winkelform aus einer flachen Folie geschnitten oder aus einem schmalen Streifen durch entsprechendes Falten zu einem Winkel geformt werden.The ribbon can be cut in an angular shape from a flat sheet of film or formed from a narrow strip by folding it into an angle will.
Um ein freies Schwingen zu ermöglichen, ist es erforderlich, dass winkelförmige Bändchen so einzuspannen, daß die beiden Schenkel auf gleicher Ebene und in einer Linie eingeklemmt werden. Die Linie, auf der die Schenkel eingeklemmt sind, müßte sich also wie die Grundlinie zu einem Dreieck verhalten. Ein mit .einem solchen Bändchen ausgerüstetes Mikrofon kann als Druckempfänger oder als Geschwindigkeitsmikrofon oder auch kombiniert arbeizen. Es kann mit einem Rohr oder Trichter durch ein passendes Zwischenstück verbunden «=erden. Zum rückwärtigen Abschluß kann es mit einem Labyrinth verbunden werden.To enable free swinging it is necessary that clamp angled ribbon so that the two legs are on the same level and pinched in a line. The line on which the legs are pinched should behave like the baseline to a triangle. A A microphone equipped with such a ribbon can be used as a pressure receiver or work as a speed microphone or in combination. It can be with a pipe or funnel connected by a suitable adapter «= earth. To the rear At the end it can be connected with a labyrinth.
Das geschilderte Bändchen läßt sich ebensogut für die Lautvriedergabe wie als schwingendes Organ in einem Lautsprecher verwenden.The ribbon described can be used just as well for sound reproduction like using it as a vibrating organ in a loudspeaker.
