Die Erfindung betrifft ein akustisches System, insbesondere ein Lautsprechersystem.The The invention relates to an acoustic system, in particular a loudspeaker system.
Der
Durch
die
Ziel des Erfindungsgegenstandes ist es, ein akustisches System, insbesondere ein Lautsprechersystem, bereitzustellen, bei welchem kritische Frequenzanteile wirksam abgeschwächt werden können. Darüber hinaus soll der Einsatz schallschluckender Materialien begrenzt werden.aim the subject of the invention is an acoustic system, in particular a speaker system to provide at which critical frequency components can be effectively mitigated. About that In addition, the use of sound-absorbing materials is limited become.
Des Weiteren soll eine akustische Laufzeitleitung vorgeschlagen werden, die insbesondere für akustische Systeme, wie beispielsweise Lautsprechersysteme, einsetzbar sein soll, mittels welcher in analoger Weise zum vorab angesprochenen akustischen System kritische Frequenzanteile wirksam abgeschwächt werden können, wobei auch hier der Einsatz von schallschluckenden Materialien auf ein Minimum beschränkt sein soll.Of Furthermore, an acoustic delay line should be proposed, in particular for acoustic systems, such as Speaker systems, should be used by means of which in analog Way to the above-mentioned acoustic system critical frequency components can be effectively mitigated, as well Here, the use of sound-absorbing materials to a minimum should be limited.
Dieses Ziel wird einerseits erreicht durch ein akustisches System, insbesondere Lautsprechersystem, zumindest beinhaltend einen durch Wandabschnitte gebildeten Korpus, mindestens einen Treiber sowie mindestens eine akustische Laufzeitleitung, die aus mehreren Hohlkörperabschnitten mit im Wesentlichen gleichem Querschnitt besteht, wobei die Hohlkörperabschnitte unter Bildung von stumpfen und/oder spitzen Winkeln räumlich versetzt zueinander angeordnet und an ihren einander zugewandten Endbereichen miteinander verbunden sind.This The goal is achieved on the one hand by an acoustic system, in particular Speaker system, at least including one by wall sections formed body, at least one driver and at least one acoustic delay line consisting of several hollow body sections with is substantially the same cross-section, wherein the hollow body sections spatially forming obtuse and / or acute angles offset from one another and at their facing each other End areas are interconnected.
Vorteilhafte Weiterbildungen des erfindungsgemäßen akustischen Systems sind den zugehörigen gegenständlichen Unteransprüchen zu entnehmen.advantageous Further developments of the acoustic according to the invention Systems are the associated representational Subclaims refer.
Unter einem akustischen System allgemeiner Art versteht der Fachmann unter anderem auch Belüftungssysteme (Leitungen), beispielsweise im Bereich eines Tonstudios, in welchem unterschiedliche Räume akustisch voneinander getrennt werden sollen.Under an acoustic system of a general kind understands the expert other ventilation systems (lines), for example in the field of a recording studio, in which different rooms acoustically separated from each other.
Im speziellen werden hier Lautsprechersysteme angesprochen, die entweder räumlich positionierbar sind oder z. B. in anderen Möbeln verdeckt eingesetzt werden.in the special speaker systems are addressed here, either are spatially positionable or z. B. in other furniture be used concealed.
Dieses Ziel wird auch erreicht durch eine akustische Laufzeitleitung, insbesondere für ein akustisches System, bestehend aus mehreren durch Wandabschnitte gebildete Hohlkörperabschnitte mit im Wesentlichen gleichem Querschnitt, die unter Bildung von stumpfen und/oder spitzen Winkeln räumlich versetzt zueinander angeordnet und in ihren einander zugewandten Endbereichen miteinander verbunden sind.This The goal is also achieved by an acoustic delay line, in particular for an acoustic system, consisting of several by wall sections formed hollow body sections with substantially the same Cross-section resulting in the formation of obtuse and / or acute angles spatially offset from each other and in their each other facing end portions are interconnected.
Vorteilhafte Weiterbildungen der erfindungsgemäßen akustischen Laufzeitleitung sind den zugehörigen gegenständlichen Unteransprüchen zu entnehmen.advantageous Further developments of the acoustic according to the invention Runtime management are the associated representational Subclaims refer.
Geringe Abweichungen des Querschnitts führen zu keiner klanglichen Verschlechterung.low Deviations of the cross-section lead to no sonic Deterioration.
Von besonderem Vorteil ist, wenn die akustische Laufzeitleitung durch entsprechende räumliche Anordnung und Verbindung der einzelnen Hohlkörperabschnitte das akustische System, insbesondere das Lautsprechersystem, unmittelbar selber bildet. Mindestens ein horizontal verlaufende Hohlkörperabschnitt kann hierbei den Fuß des akustischen Systems, insbesondere des Lautsprechersystems, bilden.From particular advantage is when the acoustic delay line through appropriate spatial arrangement and connection of the individual Hollow body sections the acoustic system, in particular the Speaker system, directly forms itself. At least one horizontal extending hollow body section can in this case the foot of the acoustic system, in particular of the speaker system.
Dem Fachmann sind für den Begriff „Laufzeitleitung” auch andere Termini, wie beispielsweise Transmissionslinie oder Transmission Line (englisch) geläufig.the Specialists are for the term "lead time management" as well other terms, such as transmission line or transmission Line (English) common.
Die Laufzeitleitung, entweder im Lautsprecher eingebaut oder das Lautsprechersystem an sich bildend, besteht aus mindestens zwei Hohlkörperabschnitten, wobei in Abhängigkeit von der Komplexität auch fünf und mehr Hohlkörperabschnitte räumlich zueinander versetzt eingesetzt werden können.The Run-time line, either built into the speaker or the speaker system forming itself, consists of at least two hollow body sections, depending on the complexity as well five and more hollow body sections spatially to each other offset can be used.
Mit dem Erfindungsgegenstand werden unter Anderem folgende Vorteile erreicht:With The subject of the invention, inter alia, the following advantages reached:
- – Durch Beugung und Streuung der Schallwellen an den Leitungsknicken der einzelnen miteinander verbundenen Hohlkörperabschnitte werden kritische Frequenzanteile, welche sonst ebenfalls über das Leitungsende der Laufzeitleitung abgestrahlt würden, wirksam abgeschwächt.- By diffraction and scattering of sound waves the line buckling of the individual interconnected hollow body sections become critical frequency components, which otherwise also over the line end of the delay line would be emitted, effectively weakened.
- – Ein verstärkter Einsatz von schallschluckenden Materialien ist bei dem Erfindungsgegenstand nicht mehr notwendig. Verfärbungen durch Resonanzen höherer Ordnung der Laufzeitleitung werden deutlich reduziert.- Increased use of sound-absorbing materials is no longer necessary in the subject invention. discoloration by higher-order resonances of the delay line significantly reduced.
- – Die weitestgehende Vermeidung der Einbringung von Dämmmaterial ermöglicht ein dynamischeres Klangbild, da weniger Energie vom Dämmmaterial absorbiert wird.- The greatest possible avoidance of the introduction of Insulating material allows a more dynamic sound, because less energy is absorbed by the insulating material.
- – Ein geringerer Dämmmaterialanteil bedeutet eine Kostenersparnis (Material- und Zuschnitts- sowie Einbringkosten).- A lower proportion of insulating material means one Cost savings (material and cutting and insertion costs).
- – Weniger Dämmmaterial bedeutet einen höheren Schalldruckpegel.- Less insulation material means a higher sound pressure level.
Neben den vorab angesprochenen Vorteilen wird darüber hinaus auch ein, gegenüber herkömmlichen, einen Korpus beinhaltenden, Lautsprechern aufweisender optischer/Design-Effekt erzielt, da die akustische Lautzeitleitung unmittelbar das akustische System, insbesondere das Lautsprechersystem, bildet. Auf weitere Wandabschnitte, wie sie den Korpus eines Lautsprechers bilden, kann somit verzichtet werden.Next the advantages mentioned above will go beyond that also a, compared to conventional, a carcass including, speakers having optical / design effect achieved, since the acoustic loudspeaker line immediately the acoustic System, in particular the speaker system forms. On more Wall sections, as they form the body of a speaker can thus be waived.
Der Korpus des akustischen Systems, insbesondere des Lautsprechersystems, kann aus Holz (z. B. Multiplex), Kunststoff, Keramik, Metall, Naturstein, Kunststein, Sandwichsystemen oder dergleichen bestehen. Dies gilt in gleicher Weise für die Laufzeitleitung. Der Fachmann wird in Abhängigkeit vom jeweiligen Anwendungsfall, respektive der gewünschten Optik des Lautsprechersystems, die geeigneten Materialien oder Kombinationen derselben auswählen.Of the Body of the acoustic system, in particular the speaker system, can be made of wood (eg multiplex), plastic, ceramics, metal, natural stone, artificial stone, Sandwich systems or the like exist. This applies in the same Way for the delay line. The expert becomes dependent of the particular application, respectively the desired appearance of the speaker system, the appropriate materials or combinations select the same.
