Abstract
Description
Die Erfindung betrifft eine Lautsprecheranordnung mit mehreren für verschiedene Frequenzen optimierten Lautsprechern, wobei einem hohen Frequenzen zugeordneten Hochton-Lautsprecher zur Schallführung ein sich dessen Schallaustrittsfläche anschließendes sich weitendes Horn aufweist, welches eine Schall-Leitfläche an seiner Innenseite bietet und wobei wenigstens ein tieferen Frequenzen zugeordneter Mittel-Tief-Ton-Lautsprecher vorgesehen ist.The The invention relates to a loudspeaker arrangement with several for different Frequencies optimized speakers, while a high frequencies associated tweeter loudspeaker for carrying sound a subsequent sound exit surface itself has wide horn, which has a sound guide surface at its Inside offers and wherein at least one lower frequencies assigned Medium-low Sound Speaker is provided.
Eine kompakte Anordnung von für verschiedene Frequenzen optimierten Einzellautsprechern in einem System zur Wiedergabe des gesamten Schallspektrums wird oft dadurch behindert, dass normalerweise Hochtönern ein Horn an deren Schallaustrittsöffnung angeordnet ist, dass zur Leitung des Schalls mit hohen Frequenzen vorgesehen ist.A compact arrangement of for different frequencies optimized single speakers in one System for reproducing the entire sound spectrum is often characterized hampers that usually tweeters a horn arranged at their sound outlet is that intended to conduct the sound at high frequencies is.
Aufgabe der Erfindung ist es eine solche Lautsprecheranordnung weiterzuentwickeln.task The invention is to further develop such a speaker assembly.
Diese Aufgabe wird durch eine Lautsprecheranordnung nach den Merkmalen des Anspruchs 1 gelöst.These Task is by a speaker assembly according to the features of claim 1.
Erfindungsgemäß ist vorgesehen, dass das Horn durch einen in seiner der Schall-Leitfläche abgewandten Seite voluminösen Körper ausgestaltet ist, wobei die schwingende Membran des wenigstens einen Mittel-Tief-Ton-Lautsprecher unmittelbar hinter dem voluminösen und massiven Körper des Horns angeordnet ist, wobei in dem voluminösen Körper des Horns zur Schwingungsebene der Membran im wesentlichen senkrecht angeordnete Kanäle ausgebildet sind, durch welche die Schallwellen des Mittel-Tief-Ton-Lautsprechers dringen können.According to the invention, it is provided that the horn facing away from one in his the sound guide surface Side voluminous body is configured, wherein the oscillating membrane of the at least one Medium-low-tone speakers immediately behind the voluminous and massive body of the horn, wherein in the voluminous body of the horn to the vibration plane the membrane formed substantially perpendicular channels are through which the sound waves of the mid-low-tone speaker can penetrate.
Hierdurch ist auf besonders effektive Weise eine optimierte Schallabstrahlung und eine kleinstmögliche kompakte Bauweise ermöglicht. Das Abstrahlverhalten ist nun gleichmäßiger über der Frequenz als bei herkömmlichen Anordnungen mit konstruktiv durch das das bisher undurchdringliche Horn bedingten beabstandeteren Schallquellen.hereby is a particularly effective way of optimized sound radiation and a smallest possible compact design allows. The radiation behavior is now more even over the frequency than with conventional ones Arrangements with constructive by the previously impenetrable Horn conditional spaced sound sources.
Bevorzugterweise ist die Schall-Leitfläche des Horns gekrümmt.preferably, is the sound-conducting surface of the Horns curved.
Von Vorteil ist der wenigstens eine Mittel-Tief-Ton-Lautsprecher unmittelbar neben der Schallaustrittsfläche des Hochton-Lautsprecher angeordnet, also in geringem Abstand.From The advantage is the at least one middle-low-tone loudspeaker immediately adjacent to the sound exit surface of the High-frequency speakers arranged, so at a small distance.
Im Falle, dass mehrere Mittel-Tief-Ton-Lautsprecher vorgesehen sind, ist von Vorteil vorgesehen, dass deren Membran-Zentren voneinander weniger als Lambda(λ)/2 der höchsten abzustrahlenden Frequenzen voneinander beabstandet sind.in the Case that several mid-low sound speakers are provided, is advantageously provided that their membrane centers of each other less than lambda (λ) / 2 of the highest frequencies to be radiated spaced apart from each other.
Bevorzugterweise ist das Material des Körpers schallhart.preferably, is the material of the body reverberant.
Nach einer besonders vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Kanäle in dem Körper einen Bandpass bilden, wobei die Anzahl der Kanäle und deren jeweilige Querschnittsfläche und Länge so gewählt sind, dass die Resonanz-Frequenz des Bandpasses nicht wesentlich unterhalb der Trennfrequenz zwischen Hochton-Lautsprecher und Mittel-Tief-Ton-Lautsprecher liegt.To a particularly advantageous embodiment of the invention is provided that the channels in the body form a bandpass, the number of channels and their respective cross-sectional area and Length like that chosen are that the resonance frequency of the bandpass is not essential below the crossover frequency between high-frequency speaker and mid-low-tone speaker lies.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen oder deren mögliche Unterkombinationen.Further advantageous embodiments will become apparent from the other dependent claims or their possible Subcombinations.
Nachfolgend wird die Erfindung anhand der Zeichnungen weiter erläutert. Im Einzelnen zeigt die schematische Darstellung in:following the invention will be further explained with reference to the drawings. in the Individual shows the schematic representation in:
