Abstract

The loudspeaker box is fitted with a woofer-subwoofer speaker combination, for handling a frequency range between 20 Hz and 200 Hz. The acoustic energy provided by the subwoofer may be divided between two physically separated horn-shaped sound transmission channels, with electrical control of the subwoofer over a narrow frequency range of 20-70 Hz.

Description

Die Erfindung betrifft eine Tieftonlautsprecherbox mit zwei vollständig voneinander getrennten Übertragungseinheiten in einem Gehäuse. Der vorzugsweise Einsatz dieser ist bei Großbeschallungsanlagen für die Reproduktion von Sprache und Musik (z. B.: Bühnentechnik, Diskotheken u.ä.).The invention relates to a woofer with two completely separate Transmission units in one housing. The preferred use of this is at Large public address systems for the reproduction of speech and music (e.g. stage technology, Discotheques, etc.).

Diese Lautsprecherkombination verbessert die sonst schwierig zu reproduzierende Baß- Tiefbaß-Wiedergabe im hohen Schalldruckbereich sowie die gesamten Übertragungseigenschaften und verringert die Abmessungen bei einem vergleichbaren konventionellen Übertrager.This speaker combination improves the otherwise difficult to reproduce bass Bass reproduction in the high sound pressure range as well as the entire Transmission properties and reduced the dimensions in a comparable conventional transformer.

Fig. 1 ist eine Darstellung, die die Anordnung dieser zusammengesetzten Lautsprecherkombination zeigt. Fig. 1 is an illustration showing the arrangement of this composite speaker combination.

Fig. 2 stellt die elektrische Ansteuerung der Tieftonlautsprecherbox dar. Fig. 2 shows the electrical control of the woofer.

Die Tieftonlautsprecherbox verbessert die Tiefbaß und zu gleichen Teilen die Mittbaß- Wiedergabe.The woofer improves the bass and in equal parts the mid-bass Reproduction.

Das Entwicklungsziel dieses Tieftonlautsprechers zur Aufnahme eines Woofer-Subwoofer in einem Gehäuse sieht primär die erheblich besseren Transportmöglichkeiten in Verbindung mit guten Übertragungseigenschaften des zu übertragenden Frequenzbereiches von ca. 20 Hz-200 Hz bei hohem Schalldruck vor.The development goal of this woofer to accommodate a woofer subwoofer in A housing primarily sees the significantly better transport options in connection with good transmission properties of the frequency range to be transmitted of approx. 20 Hz-200 Hz at high sound pressure.

Der integrierte Subwoofer arbeitet nach dem bekannten "push-pull-Verfahren", wobei die sonst üblich geschlossene Luftkammer auf einer Seite der bei den verwendeten Chassis entfällt. Anstelle der geschlossenen Luftkammer wird die dort reproduzierte Schallenergie über einen weiteren Resonanzkanal abgeführt. Der bekannte Vorteil des push-pull-Prinzip, daß sich ein Teil der Verzerrungen durch entgegengesetzten Hub der Membranen annähernd aufhebt, bleibt erhalten.The integrated subwoofer works according to the well-known "push-pull process", whereby the otherwise closed air chamber on one side of the chassis used is not applicable. Instead of the closed air chamber, the sound energy reproduced there is transmitted via a dissipated another resonance channel. The well-known advantage of the push-pull principle that a Some of the distortion due to the opposite stroke of the diaphragms cancels out receive.

Dieser Bandpaßsubwoofer ist so konstruiert, daß durch präzise Abstimmung des anteilig zu übertragende Frequenzbereich von 20 Hz-70 Hz bevorzugt übertragen wird und durch den sehr schmalbandigen Frequenzbereich ein sehr verzerrungsarmes, schalldruckstarkes Übertragungsverhalten entsteht. This bandpass subwoofer is constructed in such a way that by precise tuning of the proportion transmitting frequency range of 20 Hz-70 Hz is preferably transmitted and by the very narrow band frequency range a very low distortion, high sound pressure Transmission behavior arises.  

Der integrierte Mittbaß-Woofer arbeitet nach dem bewahrten Baßreflex-Verfahren und erreicht in dem Frequenzbereich, von ca. 70 Hz-200 Hz, ein optimal dynamisches Übertragungsverhalten. Die beiden, voneinander physikalisch und akustisch getrennten Woofer, werden auch auf dem elektrischen Weg (passiv-, aktiv-Weiche) voneinander getrennt. Dadurch kann der Mittbaß-Woofer ebenso spezialisiert auf den für dem Woofer physikalisch, akustisch und elektrisch abgestimmten Übertragungsbereich arbeiten.The integrated mid-bass woofer works according to the proven bass reflex method and achieves in the frequency range, from approx. 70 Hz-200 Hz, an optimal dynamic Transmission behavior. The two, physically and acoustically separated from each other Woofer, are also separated from each other by electrical means (passive, active crossover). This means that the mid-bass woofer can also specialize in the physical, acoustically and electrically tuned transmission range.

Diese im gesamten Tiefbaß- bis oberen Baßbereich spezialisierten Einzelkomponenten erzielen folgende Vorteile:Achieve these individual components, which are specialized in the entire deep bass to upper bass range following advantages:

  • 1. Der für den Tiefbaßbereich eingesetzte, spezielle Compound-Bandpaß-Subwoofer mit stark eingeengten Übertragungsbereich bewirkt bei geringen Abmaßen ein schalldruckstarkes, verzerrungsarmes Übertragungsverhalten.1. The special compound bandpass subwoofer used for the deep bass range with strong narrow transmission range with small dimensions creates a sound pressure low-distortion transmission behavior.
  • 2. Der Baßbereich ab 70 Hz wird von einer vorzugsweisen "hart" aufgehängtem Chassis übertragen. Die Abstrahlung tiefer Frequenzen erfordert mit üblichen Verfahrensweisen große Membranflächen und große Membranauslenkungen. Durch den Einsatz ab 70 Hz werden die zuvor benannten Nachteile auf ein Minimum reduziert. Ebenfalls sehr vorteilhaft für das gesamte Übertragungsverhalten ist, daß die in den kritischen Bereichen (unter 70 Hz) notwendigen Membranauslenkungen auf das Mittbaß-Chassis durch die elektrische Trennung unterbunden werden. Somit werden bei der Zuführung hoher elektrischer Energien die ansonsten lästigen Frequenzüberlagerungen ebenfalls physikalisch auf ein Minimum reduziert. Des weiteren wird davon ausgegangen, daß die Entlastung des Mittbaß-Chassis vom Subbaß-Bereich und der aus dem Einsatzbereich des Mittbaß-Chassis resultierenden Wellenlänge, die Membrangröße bei hohem Schalldruck verringert werden kann, ohne dabei die Übertragungseigenschaften zu beeinträchtigen.2. The bass range from 70 Hz is preferably a "hard" chassis transfer. The emission of low frequencies with usual procedures requires large membrane areas and large membrane deflections. By using from 70 Hz the aforementioned disadvantages are reduced to a minimum. Also very beneficial for the entire transmission behavior is that in the critical areas (under 70 Hz) necessary membrane deflections on the mid-bass chassis through the electrical Separation be prevented. Thus, when feeding high electrical Energize the otherwise annoying frequency overlaps also physically Minimum reduced. Furthermore, it is assumed that the discharge of the Mid-bass chassis from the sub-bass area and from the area of use of the mid-bass chassis resulting wavelength, the membrane size can be reduced at high sound pressure can without affecting the transmission properties.

Im ganzen sind die Vorteile in einer durchweg verzerrungsarmen, impulsgetreuen und schalldruckstarken Tieftonlautsprecherbox zu sehen, bei der durch die geringen Außenmaße sehr gute Transportmöglichkeiten geschaffen sind. Bei den Frequenzbereichen höher als 200 Hz ist die Übertragungsqualität zum größten Teil von den Chassis selbst und deren Kombination abhängig, wobei in Anbetracht der Einsatzfrequenz die gesamten Abmaße dementsprechend gering ausfallen können.All in all, the advantages are in a consistently low-distortion, impulsive and low-noise speaker cabinet with high sound pressure, due to the small external dimensions very good transport options are created. For frequency ranges higher than 200 Hz is the transmission quality for the most part from the chassis itself and their Combination depends, considering the frequency of use, the overall dimensions accordingly can be small.
