Description
Schaltung zu Korrektur der akustischen Gruppenlaufzeit und damit des frequenzabhängigen Phasenverhaltens von Lautsprecherchassis und Lautsprecherboxen. .'' .Circuit for correcting the acoustic group delay and thus the frequency-dependent phase behavior of loudspeaker chassis and loudspeaker boxes. .'' .
Stand der Technik » State of the art "
Bekannt sind sogenannte aktive Regelungen des akustischen Phasenverhaltens/ der akustischen Gruppenlaufzeit von Lautsprecher die sich in der der vorgeschalteten Elektronik befinden. Siehe dazu DE 44 18 360 A1. Desweiteren ist bekannt das sich durch vertikalen mechanischen Versatz das akustische Phasenverhalten/ die akustische Gruppenlaufzeit korrigieren läßt.So-called active controls of the acoustic phase behavior/acoustic group delay of loudspeakers are known and are located in the upstream electronics. See DE 44 18 360 A1. It is also known that the acoustic phase behavior/acoustic group delay can be corrected by vertical mechanical offset.
Problemproblem
Der im Schutzanspruch 1 beschriebenen Schaltung liegt zugruride eine Lösung für das Problem der Lautsprecherchassis und Lautsprecher zu schaffen, die die frequenzabhängigen akustischen Phasenverschiebung/ . Grupperilaufzeitverschiebungen beseitigt.The circuit described in claim 1 is intended to provide a solution to the problem of loudspeaker chassis and loudspeakers which eliminates the frequency-dependent acoustic phase shift/group delay shift.
LösungSolution
Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen, die gekennzeichnet sind, dadurch das parallel zum Lautsprecherchassis mehrere Kombinationen aus jeweils einem Kondensatorwert und einem Widerstandswert liegen, wobei sich Kondensator- und Widerstanswert jeweils zueinander in Reihe befinden während die sich daraus ergebenden Kombinationen aus den Werten wiederum zueinander parallel angeordnet sind und vom Lautsprecherchassis aus gesehen vor jeder weiteren Schaltung liegen.This problem is solved with the features listed in claim 1, which are characterized in that several combinations of a capacitor value and a resistance value are arranged parallel to the loudspeaker chassis, the capacitor and resistance values being in series with each other, while the resulting combinations of the values are in turn arranged parallel to each other and, as seen from the loudspeaker chassis, are located in front of any further circuit.
