Schwingungsfreies LautsprechergehäuseVibration-free loudspeaker housing

Eei Lautsprecherboxen,die derzeit auf dem Markt sind,treten u.a. dadurch 'Klangverfälschungen auf ,daß der Schall nicht allein aus den dafür bestimmten öffnungen austritt,sondern durch die Gehäusewände hindurch tritt.Loudspeaker boxes currently on the market include, among others This leads to falsification of the sound in that the sound does not only exit from the openings intended for this purpose, but through the Housing walls passes through.

Diese Biegeschwingungen der Box verursachen z.B.ein unnatürliches Wummen der Bässe.These bending vibrations of the box cause e.g. an unnatural The hum of the bass.

Das schwingungsfreie Lautsprechergehäuse wirkt diesen Eigenschwingungen entgegen.The vibration-free loudspeaker housing acts against these natural vibrations opposite.

Das Gehäuse besteht aus zwei glasf aserverstäz'kten Polyesterwannen unterschiedlicher Größe,welche ineinander gestellt werden und nur eine Verbindung an der Schallwandöffnung mittels Abstandshalter haben.The housing consists of two glass fiber reinforced polyester tubs different sizes, which are placed inside each other and only one connection to the baffle opening by means of Have spacers.

Die Wannen sind so gefertigt,daß von der inneren zur äußeren Wanne ein Abstand bzw.Hohlraum von 3-4 cm vorhanden ist. Dieser Zwischenraum wird vollständig mit feinem Sand oder ähnlich schwingungsdämpfenden Material gefüllt. Der Abstandshalter sorgt für die mechanische Festigkeit,für den nötigen Abstand der beiden Wannen und ist gleichzeitig für die Befestigung der Schallwand vorgesehen. Die Schallwand sollte aus Marmor oder Granit bestehen,kann auch aus einer leicht nach innen gewölbten,glasfaserverstärkten Polyesterplatte bestehen.The tubs are made to go from the inner to the outer There is a gap or cavity of 3-4 cm. This gap is completely covered with fine sand or similarly filled with vibration-damping material. The spacer provides the mechanical strength for the necessary distance between the two trays and is also provided for attaching the baffle. The baffle should be made of marble or granite, it can also be made of a slightly inwardly curved, glass fiber reinforced one Consist of polyester plate.

Die entscheidende Verbesserung dieser Bauweise,auch gegenüber dem Sandwichprinzip,besteht darin,daß die innere Wanne vom Lautsprecher in der Sohallwand nicht mehr zu Eigenschwingungen angeregt werden kann.The decisive improvement of this construction method, also compared to the sandwich principle, is that the inner tub from Loudspeakers in the sound wall no longer cause natural vibrations can be stimulated.

Schwingungen werden schon in der Entstehung von dem die Wanne umgebenden Sand bedämpft.Vibrations are already dampened in the formation of the sand surrounding the tub.

Somit können keine Schwingungen über die äußere Wanne hindurch treten.This means that no vibrations can pass through the outer tub.

Das Gehäuse kann vollständig aus glasfaserverstärktem Polyester gefertigt werden.The housing can be made entirely of glass fiber reinforced polyester are manufactured.
