Definitions
- the invention is concerned with the design of subwoofer loudspeakers, in particular with the simplification of the manufacturability of such boxes.
- the speaker can be formed by the fact that equipped with the speaker, etc. partition is inserted into the drawer frame by a housing housing also available in the mounting hole. Since the partition wall is provided with a cover plate, when the cover plate is larger than the mounting hole, the mounting hole is closed with the reaching of the end position of the partition in the drawer frame.
- cover plate seals the mounting opening only partially, i. not completely off, then the remaining opening can be used as a port. This eliminates the need for separate ports in the box body.
- this cover wall can be used for heat dissipation.
- the partition is additionally equipped with an amplifier unit.
- cover plate is provided with a contact strip for contacting the loudspeaker or the amplifier unit, no further mounting opening in the box housing is necessary any more, as a result of which the sealing effort is reduced.

Description
Die Erfindung befaßt sich mit der Ausbildung von Subwoofer-Lautsprecherboxen, insbesondere mit der Vereinfachung der Herstellbarkeit derartiger Boxen.The invention is concerned with the design of subwoofer loudspeakers, in particular with the simplification of the manufacturability of such boxes.
Gemäß den von der Technik ist es bekannt ein Boxengehäuse mittels einer Trennwand in zwei Volumina zu unterteilen und den Lautsprecher in die Trennwand einzusetzen. Eine solche Anordnung ist beispielsweise aus EP 0523410 bekannt. Dieser Schrift ist auch entnehmbar, daß eines der durch die Trennwand im Innern der Box gebildeten Volumina mit einem sogenannten Port versehen ist, der im Boxengehäuse angeordnet ist und der einen Luftaustausch zwischen dem Inneren des Boxengehäuses und der Box umgebenden Außenluft erlaubt. Eine Anordnung mit zwei Ports ist beispielsweise in DE 3410134 gezeigt. Obwohl die bisher beschriebenen Schriften nur die Verwendung eines Lautsprechers in der Trennwand zeigen, ist aus US 4016953 eine push-pull-Anordnung von Lautsprechern und aus EP 0379988 eine push-pull-Anordnung in Verbindung mit einer Doppelkammerbox bekannt.According to the prior art, it is known to divide a box housing into two volumes by means of a dividing wall and to insert the loudspeaker into the dividing wall. Such an arrangement is known for example from EP 0523410. This document is also removable, that one of the volumes formed by the partition wall inside the box is provided with a so-called port, which is arranged in the box housing and allows an exchange of air between the interior of the box housing and the box surrounding outside air. An arrangement with two ports is shown for example in DE 3410134. Although the fonts described so far only show the use of a loudspeaker in the partition wall, US Pat. No. 4,016,953 discloses a push-pull arrangement of loudspeakers and EP 0379988 discloses a push-pull arrangement in connection with a double-chamber box.
Diese bisher erörterten Schriften befassen sich aber hauptsächlich mit der Wirkung derartiger Boxen und enthalten daher nur wenige bzw. gar keine Angaben zu deren Ausbildung. Mit Rücksicht auf den Umstand, daß jedoch die Trennwand zumindest einen Lautsprecher trägt, kann gesagt werden, daß derartige Boxen ein zumindest aus zwei Halbschalen gebildetes Boxengehäuse aufweisen müssen. Bezogen auf die EP 0523410 gezeigte Anordnung bedeutet dies, daß das geschlossene Volumen von einem bis auf die Einbauöffnung für den Lautsprecher geschlossenen Kasten gebildet wird und daß die Trennwand, nachdem der Lautsprecher, etc. montiert ist, mittels eines das offene Volumen bildenden wannenförmigen Haube abgedeckt wird, wobei die Ränder der Haube mit dem Kasten verschraubt oder verklebt werden. Ein ebenfalls zweiteiliges Boxengehäuse ist DE 4344618 gezeigt.However, these fonts discussed so far mainly deal with the effect of such boxes and therefore contain little or no information about their training. With regard to the fact that, however, carries the partition at least one speaker, it can be said that such boxes must have a box housing formed at least from two half-shells. With reference to the arrangement shown in EP 0523410, this means that the closed volume is formed by a box closed to the loudspeaker mounting hole and that the partition is covered by a trough-shaped hood forming the open volume after the loudspeaker, etc. is mounted is, with the edges of the hood are screwed or glued to the box. A likewise two-part box housing is shown DE 4344618.
Wenngleich diese Anordnung drei Kammern bzw. Volumina aufweist, läßt sich aus dieser Schrift die Herstellung derartiger Lautsprecherboxen mit einer in der Trennwand angeordneten Lautsprecheranordnung gut ableiten. Außerdem läßt sich dieser Schrift entnehmen, daß kompliziert geformte Boxenhalbschalen bereitgestellt werden müssen, um ein derartiges Boxengehäuse auszubilden.Although this arrangement has three chambers or volumes, the production of such loudspeaker boxes with a loudspeaker arrangement arranged in the partition wall can be derived well from this document. In addition, it can be seen from this document that complicated-shaped box half-shells must be provided to form such a box housing.
In diesem Zusammenhang wird außerdem als nachteilig erachtet, daß die jeweiligen Boxenhalbschalen zur Gewährleistung des späteren Einbaues von Lautsprechern mittels separater Werkzeuge hergestellt werden müssen, was die Herstellung zusätzlich verteuert.In this context, it is also considered disadvantageous that the respective box halves must be made to ensure the subsequent installation of speakers by means of separate tools, which in addition makes the production more expensive.
Daher liegt der Erfindung die Aufgabe zugrunde, eine Subwoofer-Lautsprecherbox anzugeben, welche die gemäß den von der Technik bestehenden Probleme bei der Herstellung vermeidet.It is therefore an object of the invention to provide a subwoofer loudspeaker box which avoids the manufacturing problems of the prior art.
Diese Aufgabe wird durch die in Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Aus- und Weiterbildungen der Erfindung sind den Ansprüchen 2 - 5 entnehmbar.This object is achieved by the features specified in claim 1. Advantageous embodiments and further developments of the invention are the claims 2-5 removed.
Es ist das Boxengehäuse einteilig ausgebildet und an seiner Innenwand mit einem angeformeten Einschubrahmen versehen, läßt sich die Lautsprecherbox dadurch ausbilden, daß die mit dem Lautsprecher, etc. bestückte Trennwand in den Einschubrahmen durch eine im Boxengehäuse außerdem vorhandene Montageöffnung eingeschoben wird. Da die Trennwand mit einer Abdeckplatte versehen ist, wird, wenn die Abdeckplatte größer ist als die Montageöffnung, die Montageöffung mit dem Erreichen der Endlage der Trennwand im Einschubrahmen verschlossen.It is the box body formed in one piece and provided on its inner wall with a molded-in slide frame, the speaker can be formed by the fact that equipped with the speaker, etc. partition is inserted into the drawer frame by a housing housing also available in the mounting hole. Since the partition wall is provided with a cover plate, when the cover plate is larger than the mounting hole, the mounting hole is closed with the reaching of the end position of the partition in the drawer frame.
Dichtet die Abdeckplatte die Montageöffnung nur teilweise d.h. nicht vollständig ab, kann die dann verbleibende Öffnung als Port genutzt werden. Hierdurch werden separate Ports im Boxengehäuse überflüssig.If the cover plate seals the mounting opening only partially, i. not completely off, then the remaining opening can be used as a port. This eliminates the need for separate ports in the box body.
Ist zumindest die Abdeckwand aus Metall gebildet, kann diese Abdeckwand zur Wärmeabfuhr genutzt werden. Letzteres ist insbesondere dann vorteilhaft, wenn die Trennwand zusätzlich mit einer Verstärkereinheit bestückt ist.If at least the cover wall formed of metal, this cover wall can be used for heat dissipation. The latter is particularly advantageous if the partition is additionally equipped with an amplifier unit.
Ist die Abdeckplatte mit einer Kontaktleiste zur Kontaktierung des oder der Lautsprecher bzw. der Verstärkereinheit versehen, sind keine weitere Montageöffnung im Boxengehäuse mehr notwendig, wodurch der Abdichtaufwand reduziert wird.If the cover plate is provided with a contact strip for contacting the loudspeaker or the amplifier unit, no further mounting opening in the box housing is necessary any more, as a result of which the sealing effort is reduced.

Figur 1 zeigt in ein im wesentlich geschlossenes etwas quaderförmig ausgebildetes Boxengehäuse (10), wobei die Außenhaut (11) dieses Gehäuses (10) lediglich von einer Montageöffnung (12) und einem kanalförmig ausgebildeten Port (13) durchbrochen ist. Ferner ist das Innere des Boxengehäuses (10) von 4 röhrenförmigen Durchzügen (14) durchzogen, welche zur mechanischen Stabilität des Boxengehäuses (10) beitragen.FIG. 1 shows a box housing (10) which is substantially closed in a somewhat cuboidal shape, wherein the outer skin (11) of this housing (10) is only interrupted by a mounting opening (12) and a channel-shaped port (13). Furthermore, the interior of the box housing (10) of 4 tubular passages (14), which contribute to the mechanical stability of the box housing (10).
Ferner ist im in Figur 1 dargestellten Boxengehäuse (10) ist an der Innenwand (15) des Gehäuses ein Einschubrahmen (16) ausgebildet, der, wie die linke Seite der Darstellung in Figur 1 zeigt, ein etwa u-förmig ausgebildetes Profil aufweist. Der rechter Seits in der Darstellung Figur 1 ist entnehmbar, daß der Einschubrahmen (16) dort endet, wo Außenhaut (11) des Gehäuses (10) die Montageöffnung (12) aufweist. Letzteres ist wesentlich um - wie noch später gezeigt werden wird - die Lautsprecherbox zu komplettieren.Furthermore, in the box housing (10) shown in FIG. 1, a slide-in frame (16) is formed on the inner wall (15) of the housing, which, as the left side of the illustration in FIG. 1 shows, has an approximately U-shaped profile. The right side in the illustration Figure 1 is removable, that the insertion frame (16) ends where the outer skin (11) of the housing (10) has the mounting opening (12). The latter is essential - as will be shown later - to complete the speaker.
Die bisher im Zusammenhang mit Figur 1 gezeigten Verhältnisse werden in Figur 2 weiter veranschaulicht. Auch ist die Darstellung gemäß Figur 2, welchen einen Schnitt AA gemäß Figur 1 zeigt, entnehmbar, daß der Einschubrahmen (16) an den beiden Seitenflächen 17.1 und 17.2 sowie an der Stirnfläche (18) der Innenwandung (16) entlangläuft.The relationships previously shown in connection with Figure 1 are further illustrated in Figure 2. Also, the illustration according to FIG. 2, which shows a section AA according to FIG. 1, can be seen that the insertion frame (16) runs along the two side surfaces 17.1 and 17.2 as well as on the end face (18) of the inner wall (16).
Nur der Vollständigkeit halber sei darauf hingewiesen, daß das in Figur 1 und 2 gezeigte Boxengehäuse (10) sehr einfach aus Kunststoff durch Anwendung des Rotationssinterns oder Anwendung der Blastechnik hergestellt werden kann.For the sake of completeness, it should be pointed out that the box housing (10) shown in FIGS. 1 and 2 can be made very easily from plastic by using rotational sintering or application of the blowing technique.
In Figur 3 ist ein Akustikmodul (19) gezeigt. Dieses Akustikmodul (19) wird im wesentlichen von einer Trennwand (20), eine mit der Trennwand (20) verbundenen Abdeckplatte (21), einem Lautsprecher (23) und einer Verstärkereinheit (24) gebildet. In der Trennwand (20) ist eine Öffnung (22) ausgebildet, über welcher der Lautsprecher (23) montiert ist. Die Kühlkörper (25) der Verstärkereinheit (24) sind mit der Abdeckplatte (21) und (20) verbunden, welche im vorliegenden Ausführungsbeispiel zu besseren Wärmeleitung aus Metall gebildet ist.FIG. 3 shows an acoustic module (19). This acoustic module (19) is essentially formed by a partition wall (20), a cover plate (21) connected to the partition wall (20), a loudspeaker (23) and an amplifier unit (24). In the partition (20) has an opening (22) is formed, over which the speaker (23) is mounted. The heat sinks (25) of the amplifier unit (24) are connected to the cover plate (21) and (20), which is formed in the present embodiment for better heat conduction from metal.
Sofern die Wärmeableitung nur eine untergeordnete Rolle spielt oder in einem anderen - nicht dargestellten - Ausführungsbeispiel auf den Einsatz einer Verstärkereinheit (24) verzichtet wird, kann die Abdeckplatte (21) auch aus Kunststoff gebildet sein und ggf. eine einstöckige Einheit mit der Trennwand (20) bilden.If the heat dissipation plays only a minor role or in another - not shown - embodiment of the use of an amplifier unit (24) is omitted, the cover plate (21) may also be formed of plastic and possibly a single-unit with the partition (20 ) form.
Ferner ist die Abdeckplatte (21) mit Anschlußleiste (26) zur Kontaktierung der Verstärkereinheit (24) versehen.Further, the cover plate (21) with terminal block (26) for contacting the amplifier unit (24) is provided.
Wird nun ein vollständig bestücktes Akustikmodul (19) gemäß Figur 3 mit dem Umfangsrand (27) der Trennwand (20) durch die Montageöffnung (12) Figur 1 in den Einschubrahmen (16) eingeschoben, wird eine Einbausituation erreicht, welche in der Figur 4 gezeigt ist. Hat das Akustikmodul (19) seine Endlage im Boxengehäuse (10) eingenommen, verschließt die Abdeckplatte (21) die Montageöffnung (12). Außerdem wird in dieser Endlage das Innere des Boxengehäuses (10), weil der Umfangsrand (27) der Trennwand (20) im Einschubrahmen (16) gelagert ist, in ein geschlossenes Volumen (28.1) und ein offenes Volumen (28.2) unterteilt. Der Vollständigkeit sei darauf hingewiesen, daß der Umfangsrand (27) der Trennwand (20) mit einer Dichtung (29) versehen ist, um die gegenseitige Abdichtung der beiden Volumina (28.1) und (28.2) zu gewährleisten. Auch ist zwischen der Abdeckplatte (21) und der Außenhaut (11) des Boxengehäuses (10) eine Dichtung (29) vorgesehen.If now a completely populated acoustic module (19) according to FIG. 3 with the peripheral edge (27) of the dividing wall (20) is pushed through the mounting opening (12) FIG. 1 into the slide-in frame (16), an installation situation is achieved which is shown in FIG is. If the acoustic module (19) has assumed its end position in the box housing (10), the cover plate (21) closes the mounting opening (12). In addition, in this end position, the interior of the box housing (10), because the peripheral edge (27) of the partition (20) is mounted in the drawer frame (16), divided into a closed volume (28.1) and an open volume (28.2). For completeness it should be noted that the peripheral edge (27) of the partition (20) is provided with a seal (29) to ensure the mutual sealing of the two volumes (28.1) and (28.2). Also, a seal (29) is provided between the cover plate (21) and the outer skin (11) of the box body (10).
Figur 5 zeigt eine gegenüber Figur 4 leicht modifizierte Ausführung. Gemäß Figur 5 ist der Port (13) nicht durch die Außenhaut (11) des Boxengehäuses selbst geführt, sondern in der Abdeckplatte (21) ausgebildet. Auch hier ist der Port (13) rohrförmig gestaltet.FIG. 5 shows a slightly modified embodiment in comparison to FIG. According to Figure 5, the port (13) is not guided by the outer skin (11) of the box body itself, but in the cover plate (21) is formed. Again, the port (13) is tubular.
Sofern kein rohrförmiger Port (13) notwendig ist, kann die in jedem Falle erforderliche Portöffnung auch mittels einer Bohrung in der Abdeckplatte (21) oder dadurch realisiert sein, daß die Abdeckplatte (21) die Montageöffnung (12) im Boxengehäuse (10) nicht vollständig überdeckt.Unless a tubular port (13) is necessary, the port opening required in each case can also be realized by means of a bore in the cover plate (21) or by the cover plate (21) not completely completing the mounting opening (12) in the box housing (10) covered.
