Abstract
Description
Die Erfindung betrifft einen Koaxiallautsprecher der im Anspruch 1 bis 11 genannten Art. Koaxiallautsprecher sind zwar allgemein bekannt, es soll jedoch eine kurze Zusammenfassung der Gründe folgen, die zu der Motivation führen, Bauarten dieses Lautsprechertyps zur Schallerzeugung einzusetzen.The invention relates to a coaxial loudspeaker of the type mentioned in
Bei der einfachsten Methode, den gesamte hörbare Frequenzbereich von einem System alleine – einem Breitbandlautsprecher – abzustrahlen, müssen stets deutliche Kompromisse in der Klangqualität eingegangen werden. Dies sind eine eingeschränkte Wiedergabe im oberen und/oder unteren Bereich des Frequenzspektrums, Einbußen der Klangqualität in bestimmten Frequenzbereichen, Begrenzung des erzielbaren Schalldrucks und im Regelfall eine Einschränkungen der Abstrahlcharakteristik. Die abstrahlende Membran muss für die Wiedergabe hoher Frequenzen leicht sein und für tiefe Frequenzen groß und damit schwer, was physikalisch unvereinbar ist. Auf der anderen Seite können sich Lautsprecher, bei denen das gesamte Frequenzspektrum bzw. der überwiegende Teil des hörbaren Frequenzspektrums aus einer einzigen, räumlich sehr begrenzten Schallquelle abgestrahlt wird, durch eine bessere räumliche Abbildung von Musikaufnahmen und häufig eine variablere Position des Hörorts bei guter Klangqualität auszeichnen.The simplest way to emit the entire audible frequency range from a single system - a full-range speaker - always requires significant compromises in sound quality. These are a limited reproduction in the upper and / or lower range of the frequency spectrum, loss of sound quality in certain frequency ranges, limitation of the achievable sound pressure and, as a rule, a restriction of the emission characteristic. The radiating membrane has to be light for high frequency reproduction and large for low frequencies, and thus heavy, which is physically incompatible. On the other hand, speakers in which the entire frequency spectrum or the predominant part of the audible frequency spectrum is radiated from a single, spatially very limited sound source, by better spatial imaging of music recordings and often a more variable position of the listening site with good sound quality ,
Hier liegen die Nachteile der konventionellen Mehrwege-Lautsprecher. Bei diesen werden die Frequenzbereiche auf elektronischem Wege (mit passiven Frequenzweichen oder aktiver Auftrennung vor der Endverstärkung) aufgetrennt, und dann separaten Lautsprechersystemen (z. B. Tief- Mittel- und Hochtöner) zugeführt, die in ihrem jeweilig zugeordneten Frequenzbereich klanglich besser optimiert werden können als ein Breitbandsystem. Diese Systeme müssen jedoch zwangsweise in räumlicher Distanz zueinander angeordnet werden, was insbesondere im Übergangsbereich zwischen den Systemen zu Laufzeitdifferenzen (Phasenunterschieden) führt, welche insgesamt die Klangwiedergabe negativ beeinträchtigt. Selbst bei aktiver oder passiver Frequenzaufteilung mit bestimmten Filterarten (Linkwitz-Filter), die auf genau definierter Hörachse optimale Phasenverläufe aufweisen, sind diese Nachteile bei geringer Variation der Hörposition sofort wieder präsent, und der gesamte Frequenzbereich wird nichtsdestotrotz über mehrere akustische Zentren erzeugt, was die Motivation für konzentrisch abstrahlende Schallerzeuger darstellt.Here are the disadvantages of conventional multi-way speakers. In these, the frequency ranges are separated electronically (with passive crossovers or active separation before the final amplification), and then fed to separate speaker systems (eg low- midrange and tweeter), which can be better sound optimized in their respective assigned frequency range as a broadband system. However, these systems must be arranged forcibly in spatial distance from each other, resulting in particular in the transition region between the systems to runtime differences (phase differences), which affects the overall sound reproduction negative. Even with active or passive frequency distribution with certain types of filters (Linkwitz filter), which have optimal phase curves at a well-defined Hörachse, these disadvantages are immediately present again with little variation of the listening position, and the entire frequency range is nonetheless generated over several acoustic centers, which the Motivation for concentric radiating sound generator represents.
Bereits vor über 60 Jahren wurden erste ausgereifte Versionen von Koaxiallautsprechern entwickelt (z. B. Altec 601 und 604E), die eine konzentrische Anordnung des Bassmembranlautsprechers mit einer im Antriebssystem des Basses integrierten Hochtoneinheit mit einem der Bassmembran vor geschalteten Horn aufwiesen. Andere Systeme (Tannoy Monitor Black) verwendeten eine ähnliche Antriebseinheit und nutzten die hornförmige Form der Membran des Basslautsprechers als Hochtonhorn. Beiden kommerziell erfolgreichen Prinzipien, die in neueren Patenten weiterentwickelt wurden (z. B.
Die hier dargelegte Erfindung löst die genannten Probleme des Stands der Technik gemäß den Ansprüchen 1 bis 11 durch ein gänzlich anderes Funktionsprinzip. Der Karlson-Koppler (Pat.
Durch die in der vorliegenden Erfindung dargestellte Anordnung des Karlson-Kopplers in Kombination mit einem konventionellen Tief-Mitteltonsystem lässt sich ein Koaxiallautsprecher bauen, der ohne elektronische Maßnahmen phasengleiche Schallabstrahlung beider Systeme bei hohem Wirkungsgrad und linearer Frequenzwiedergabe ermöglicht. Erfindungsgemäß kann durch die im Vergleich zu einem Hochtonhorn schlanke Bauform einer Röhre gemäß
