Lautsprecherabdeckung oder -VerkleidungSpeaker cover or fairing
Bei Betrieb von Lautsprechern ist es wichtig, dass die den oder die Lautsprecher in Abstrahlrichtung abdeckende oder schützende Bespannung keine schallschluckende oder reflektierende Wand bildet, sondern alle Frequenzen (Töne) ungehindert durchlässt. Es ist bekannt, Lautsprecher, z.B. bei Radio- oder Verstärkeranlagen, mit Textilgewebe, perforierten Blechen oder Streckmetall abzudecken. Diese Materialien schwingen mit, was an sich für Sprach-Übertragungen nicht weiter störend wirkt. Anders ist es jedoch bei Musikübertragungen, vor allem dann, wenn hochempfindliche Lautsprecher, z.B. in Stereoanlagen, vorgesehen sind. Was nützt es, wenn Empfangs- und Verstärkerteil die für das menschliche Ohr wahrnehmbaren Frequenzen von ca. 16 bis 16.000 Hz. zu den Lautsprechern leiten, das letzteWhen using loudspeakers, it is important that the or Covering or protecting the loudspeakers in the direction of radiation does not form a sound-absorbing or reflective wall, but lets through all frequencies (tones) unhindered. It is known, Loudspeakers, e.g. for radio or amplifier systems, with textile fabric, to cover perforated sheets or expanded metal. These materials resonate with what is in itself for speech transmissions does not have a further disturbing effect. The situation is different with music transmissions, especially when highly sensitive loudspeakers, e.g. in stereos, are provided. What good is it if the receiver and amplifier part have the frequencies perceptible to the human ear? from approx. 16 to 16,000 Hz. to the loudspeakers, the last one

Aufgabe der Erfindung ist es, für Lautsprecher eine geeignete Abdeckung mit guten akustischen Eigenschaften zu finden, die die abgestrahlten Frequenzen durchlässt und die in allen Tonbereichen keine Eigenschwingung ausführt.The object of the invention is to find a suitable cover for loudspeakers with good acoustic properties that match the radiated Lets frequencies through and does not carry out any natural oscillation in any tone range.
Versuche etmit normalen Drahtgeweben brachten keine wesentliche Besserung.Attempts with normal wire mesh did not yield any substantial results Improvement.
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass zur Abdeckung oder Verkleidung die Lautsprecher oder Lautsprecher-Boxen in Abstrahlrichtung mit einem kalanderten Drahtgewebe bespannt sind.The object is achieved according to the invention in that for covering or clad the loudspeakers or loudspeaker boxes in the direction of radiation are covered with a calendered wire mesh.
Überraschenderweise wurde nämlich gefunden, dass kalandertes Drahtgewebe, welches an sich bekannt ist, die von den Lautsprechern oder akustischen Wandlern abgestrahlten Schwingungen ungehindert passieren lässt und nicht mitschwingt, so dass Übertragungen, sei es von Radio-, Schallplatten- oder Tonband-Anlagen, wesentlich besser wÄerden. Das kalanderte Drahtgewebe, kann beispielsweise aus Aluminium- oder Messingdrähten hergestellt sein.Surprisingly, it was found that calendered wire mesh, which is known per se, that of the loudspeakers or acoustic transducers allows radiated vibrations to pass unhindered and does not resonate, so that transmissions are it would be much better from radio, record or tape systems. The calendered wire mesh, for example be made of aluminum or brass wires.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung wiedergegeben.An exemplary embodiment of the invention is shown in the drawing.
Fig. 1) zeigt eine Lautsprecherbox mit kalandertem Drahtgewebe. Fig. 2) zeigt eine Draufsicht auf ein kalandertes Drahtgewebe.Fig. 1) shows a loudspeaker box with calendered wire mesh. Fig. 2) shows a plan view of a calendered wire mesh.
In einer für Lautsprecher geeigneten Box 1 sind in Fig. 1 beispielsweise ein Hochton-Lautsprecher 2 und ein Tiefton-Lautsprecher 3 eingebaut. Die Box ist an der Frontseite, also in Abstrahlrichtung, mit kalandertem Drahtgewebe 4 verkleidet. In Fig. 2 ist ein Ausschnitt aus kalandertem Gewebe dargestellt.In a box 1 suitable for loudspeakers in FIG. 1, for example a tweeter 2 and a woofer 3 built in. The box is clad with calendered wire mesh 4 on the front side, that is, in the direction of radiation. In Fig. 2 a section of calendered fabric is shown.
