Beschreibung des Baßreflexgehäuses für den mobilen EinsatzDescription of the bass reflex housing for mobile use
Es war mir nicht möglich die z.Zt. im Handel angebotenen großvolumigen Lautsprecherboxen meiner Gesangsanlage in den Kofferraum meines Fahrzeuges zu verstauen.It was not possible for me to in the trade offered large-volume To stow the loudspeaker boxes of my vocal system in the trunk of my vehicle.
Von diesem Problem habe ich während meiner Auftrittsreiesn auch von anderen Künstlern gehört.I heard about this problem from other artists during my performance tours.
Entweder mußten sie zur Beförderung ihrer Boxen ein anderes Fahrzeug mieten oder sie mußten auf die Boxen verzichten. Es gibt zwar die Möglichkeit im Volumen kleinere Boxen zu benutzen, diese sind aber auf Grund ihres Volumens nicht- so gut geeignet, um damit in Sälen vor Publikum aufzutreten.Either they had to use another vehicle to move their boxes rent or they had to do without the boxes. Although there is the possibility of using smaller boxes in terms of volume, However, due to their volume, these are not so well suited to perform in halls in front of an audience.
Es ist allgemein bekannt, aaß großvolumige Lautsprecherboxen einen größeren Wirkungsgrad haben. Daraus war abzuleiten, daß meine Lautsprechergehäuse in Betrieb nicht verändert werden durften. Für den Transport mußten die großvolumicen Boxen jedoch verkleinert werden.It is well known that large volume loudspeaker boxes ate one have greater efficiency. From this it could be deduced that my loudspeaker enclosures were not allowed to be changed during operation. However, the large-volume boxes had to be reduced in size for transport will.
Das Problem der Verkleinerung war zwar kein Geringes, aber es wurde von mir gelöst.The downsizing problem was not a small one, but it was solved by me.
Ich habe mir die Daten eines handelsüblichen Lautsprechergehäuses genfimmen und danach eine Lautsprecherbox gebaut.I genfimmed the data of a commercially available loudspeaker housing and then built a loudspeaker box.
Diese war jedoch in den Abmessungen zu groß um sie in den Kofferraum meines Fahrzeuges zu bekommen.However, this was too big to fit in the trunk to get my vehicle.
Ich habe danach die Lautsprecherbox längs geteilt und für meine Bedürfnisse wie folgt umgebaut:I then divided the speaker box lengthways and rebuilt it for my needs as follows:
Damit die Boxen transportabel werden sollten, habe ich die Innenabmessungen des Hinterteils so gewählt, daß sie den Außenabmessungen des Vorderteils entsprechen.So that the boxes should be transportable, I have the inside dimensions of the rear part chosen so that they correspond to the outer dimensions of the front part.
Damit ist das Prinzip der Streichholzschachtel übernommen worden. Somit konnte ich das Vorderteil der Box, daß man um 180 Grad um die Längsachse dreht, in das Hinterteil der Box geschoben werden. Es wurde so eine Platzersparnis bei der Beförderung von ca. if5/, erzielt.The principle of the matchbox has thus been adopted. So I was able to turn the front part of the box that you can turn 180 degrees rotates the longitudinal axis, can be pushed into the back of the box. There was such a space saving in the transport of approx. If5 /, achieved.
Das Hauptproblem lag jedoch bei der Aufstellung der Box bzw. bei der Inbetriebnahme.The main problem, however, was the installation of the box and the commissioning.
Beim Betreiben einer so großvolumigen Lautsprecherbox entstehen, innerhalb des Gehäuses, durch die Schwingungen der Lautsprecher, Drücke. Bei einer geschlossenen Box kann der Druck nicht entweichen und dienst so wesentlich zur Tonverbesserung. Da meine Box alsWhen operating such a large-volume loudspeaker box, inside the housing, due to the vibrations of the loudspeakers, pressures. If the box is closed, the pressure cannot escape and serve so essentially to improve the sound. Since my box as a
