Abstract
Lautsprecheranordnung mit entkoppelten Gehäusen zur schwingungsfreien Bass- und Mittelhochtonwiedergabe, dadurch gekennzeichnet, dass die im Bassgehäuse montierten Basslautsprecher stets gegenüber montiert sind und mit gegenläufigen Membranbewegungen arbeiten, oder derart montiert sind dass sich die Membranmassenmomente gegenseitig aufheben.Loudspeaker arrangement with decoupled housings for vibration-free bass and mid high-frequency reproduction, characterized in that the bass speakers mounted in the bass cabinet are always mounted opposite and work with opposite membrane movements, or are mounted such that the membrane mass moments cancel each other.
Description
Die Erfindung betrifft die Anordnung von Basslautsprechern in Bassgehäusen und Mittelhochtongehäuse in abgekoppelter Bauweise, wobei sich die Membranen der Basslautsprecher im Gegentakt bewegen und das Mittelhochtongehäuse beweglich mit Entkoppelungselementen am Bassgehäuse befestigt ist.The The invention relates to the arrangement of woofers in bass cabinets and Mittelhochtongehäuse in decoupled construction, whereby the membranes of the bass speakers move in push-pull and the middle high-frequency housing movable with decoupling elements on the bass cabinet is attached.
Bei den bekannten Lautsprechersystemen mit nur einem Basslautsprecher oder auch mehreren in gleicher Richtung montierten treten im Gehäuse von der Lautstärke abhängige Rückkopplungen und materielle Resonanzen bedingt durch die bewegten Membranmassen auf, die auf den Abhörraum und Geräte einwirken und bei höherem Lautstärkepegel Störungen verursachen können. Abhilfe mit vielfältigen Entkopplungskonen (Spikes) u. ä., oder Gehäuse mit hohem Eigengewicht (z. B. aus Stein) können die mechanischen Schwingungen, bedingt durch die bewegten Membranmassen, weitestgehend unterdrücken. Eine geringe, von der Lautstärke abhängige Rückkopplungen durch materielle Resonanzen bleiben jedoch immer zurück.at the well-known speaker systems with only one bass speaker or several mounted in the same direction occur in the housing of the volume dependent feedback and material resonances due to the moving membrane masses on top of the listening room and devices act and at higher Volume level cause interference can. Remedy with diverse Decoupling cones (spikes) u. ä., or housing With a high weight (eg made of stone), the mechanical vibrations, due to the moving membrane masses, suppress as far as possible. A low, from the volume dependent feedbacks however, material resonances always lag behind.
Die Lautsprecheranordnung mit den im Gegentakt arbeitenden Membranen hebt die durch die bewegten Membranmassen entstehende Schwingung des Bassgehäuses auf. Ein weiterer, mit dieser Erfindung erzielter Vorteil besteht in der Einrichtung eines separaten Gehäuses zur Mittel- und Hochtonwiedergabe, mit dem zusätzlich noch die auf die im normalen Gehäuse vorhandenen Unterteilungen für Mittel- und Hochton einwirkenden, starken Druckschwankungen durch den Basslautsprecher entfallen.The Loudspeaker arrangement with push-pull diaphragms lifts the vibration caused by the moving masses of the membrane of the bass enclosure on. Another advantage obtained with this invention is in the establishment of a separate housing for medium and high-frequency reproduction, with the addition still on the normal case existing subdivisions for central and high-pitched, strong pressure fluctuations through the bass speaker omitted.
Eine geometrische Anordnung von mehreren Basslautsprecher im Gehäuse sollte stets mit sich gegenüberliegenden Membranen und gleichen Bewegungsachse erfolgen, d. h. die Basslautsprecher sind symmetrisch zueinander auf den Montageplatten zu montieren, wobei die Membranbewegungen gegenläufig verlaufen müssen. Dabei sollte der spiegelsymmetrische Aufbau der einzelnen Gehäuse beachtet werdenA Geometric arrangement of several woofers in the housing should always facing each other Membranes and same axis of motion take place, d. H. the bass speakers are symmetrically to each other to mount on the mounting plates, wherein the membrane movements in opposite directions have to go. The mirror-symmetrical structure of the individual housings should be taken into consideration become
Weiterhin erlaubt die Erfindung die Ausgestaltung eines beweglichen Mittel- und Hochtongehäuses, um eine universelle Verwendung des Lautsprechers als Direktstrahler, Indirektstrahler oder Nahfeldlautsprecher. Als besonders vorteilhaft hat sich die Anordnung der Treiber für den Mitteltonbereich erwiesen, in dem diese auf eine hornartige Schallaustrittsöffnung arbeiten, wobei die Treiber quer zur Schallrichtung eingebaut sind.Farther the invention allows the design of a mobile central and tweeter housing, to a universal use of the speaker as a direct radiator, Indirect or near field loudspeaker. As a particularly advantageous the arrangement of the drivers for the midrange has proven in which they work on a horn-like sound outlet, wherein the Driver are installed transversely to the sound direction.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist die zusätzliche im Innenteiler angeordnete Innenmembran (Synchronmembran) wirkt Phasenfehlern der einzelnen Basslautsprecher entgegen und ist elektrisch und mechanisch abgleichbar.A Another advantageous embodiment of the invention is the additional arranged in the inner divider inner membrane (synchronous diaphragm) acts Phase errors of each subwoofer and is electrical and mechanically adjustable.
