Abstract
Description
Titel: Passive LautsprechermembraneTitle: Passive loudspeaker membrane
Beschreibung Die vorliegende Erfindung hat den Zweck, passive Lautsprechermembranen wesentlicher wirtschaftlicher herzustellen als bisher. Description The present invention aims to provide passive speaker diaphragms more economical to manufacture than before.
Passive Lautsprechermembranen werden anstelle von Baßreflexöffnungen zur Qualitätsverbesserung in Lautsprechergehäuse eingebaut und überwiegend hergestellt wie aktive Lautsprecherchassis nur ohne Magnet systeme und Schwingspulen.Passive speaker diaphragms are used instead of bass reflex ports built into loudspeaker housings to improve quality and mostly manufactured like active loudspeaker chassis only without magnet systems and voice coils.
Bei der vorliegenden Erfindung wird die passive Lautsprechermembrane und die Sickenaufhängung (in der Zeichnung mit 1 bezeichnet) in einem einzigen maschinellen Arbeitsgang aus Styropor oder anderen geeigneten Materialien hergestellt. Dabei wird eine flexible Sicke (in der Zeichnung mit 2 bezeichnet) in eine entsprechende Form eingelegt. Nach Schließen der Form wird das Styropor eingefüllt und bildet fest verschweißt mit der flexiblen Sicke einerseits die Sickenaufhängung und andererseits die Membrane (in der Zeichnung mit 3 bezeichnet).In the present invention, the passive speaker diaphragm and the bead suspension (denoted by 1 in the drawing) in a single machine Operation made of styrofoam or other suitable materials. Included is a flexible bead (designated in the drawing with 2) in a corresponding Form inserted. After closing the mold, the styrofoam is poured in and forms firmly welded to the flexible bead on the one hand the bead suspension and on the other hand the membrane (marked 3 in the drawing).
Die Vorteile dieser Herstellungstechnik sind: 1. Die passive Lautsprechermembrane und die Sickenaufhängung sind beliebig in Formgebung und Aufschäumungsdichte.The advantages of this manufacturing technique are: 1. The passive loudspeaker membrane and the bead suspension are of any shape and foam density.
2. Bei Gehäuse- oder Rückwandkonstruktionen für Lautsprecherboxen aus Styropor können passive Lautsprechermembranen beim Herstellungsvorgang gleichzeitig mit eingeschäumt werden. Dabei können Gehäuse oder Rückwand und passive Lautsprechermembrane verschieden hart aufgeschäumt werden.2. In case or back wall constructions for loudspeaker boxes Made of Styrofoam, passive loudspeaker cones can be used in the manufacturing process at the same time be foamed with. The housing or rear wall and passive loudspeaker membrane can be used be foamed at different levels of hardness.
3. Die Herstellungskosten betragen insbesondere bei Letztgenannten Konstruktionen nur einen kleinen Teil gegenüber herkömmlicher Bauweise.3. The production costs are particularly in the case of the latter Constructions only a small part compared to conventional construction.
