Abstract

A loudspeaker (10) with bayonet fixing noses (17) also exhibits, apart from the features known from conventional speakers of this type, projections 19 which are constructed in such a manner that they cover insertion slots (15) on the holding device (11) when the speaker is assembled. Due to the projections, so-called acoustic shorts are avoided in the case of open loudspeakers. This considerably improves the acoustic characteristics. <IMAGE>

Description

Die Erfindung betrifft einen Lautsprecher mit Bajonettverschluß, also einen Lautsprecher, der an einer Haltevorrichtung durch axiales Einschieben in dieselbe und anschließendes Verdrehen um einen geringen Winkel befestigt wird.The invention relates to a loudspeaker with a bayonet catch, that is to say a loudspeaker which is fastened to a holding device by being axially pushed into it and then rotated through a small angle.

Lautsprecher mit Bajonettverschluß weisen Bajonettverschlußnasen an einem kreisförmigen Befestigungsring an demjenigen Ende des Lautsprechers auf, das in Abstrahlungsrichtung am weitesten vorne liegt. Dieses Ende wird im folgenden als vorderes Ende bezeichnet. Die Lagebegriffe "vorne" und "hinten" sind gemäß dieser Definition zu verstehen.Speakers with a bayonet catch have bayonet catches on a circular fastening ring at the end of the loudspeaker that is furthest forward in the direction of radiation. This end is referred to below as the front end. The terms "front" and "rear" are to be understood in accordance with this definition.

Außer Lautsprechern mit Bajonettverschluß gibt es insbesondere solche, die im Befestigungsring Löcher zum Durchschieben von Schrauben aufweisen. Zum Befestigen wird der Befestigungsring auf einen Haltering aufgesetzt, und dann werden Befestigungsschrauben durch die Löcher im Befestigungsring in den Haltering gedreht.In addition to speakers with a bayonet lock, there are in particular those that have holes in the fastening ring for pushing screws through. To attach, the mounting ring is placed on a retaining ring, and then mounting screws are screwed through the holes in the mounting ring into the retaining ring.

Es hat sich immer wieder herausgestellt, daß Lautsprecher mit Bajonettverschluß schlechtere akustische Eigenschaften aufweisen als Lautsprecher mit anderen Befestigungseinrichtungen, insbesondere Lautsprecher, die mit Schrauben befestigt werden. Lautsprecher mit Bajonettverschluß wurden daher nicht für Lautsprechereinrichtungen hoher Qualität eingesetzt. Aufgrund der mit Lautsprechern mit Bajonettverschluß im Vergleich zu anderen Lautsprechern geringen Montagekosten besteht jedoch seit langem der Wunsch, Lautsprecher mit Bajonettverschluß zur Verfügung zu haben, die bei sonst gleichem Aufbau ebensogute akustische Eigenschaften haben wie Lautsprecher mit anderen Befestigungsarten, insbesondere Lautsprecher, die mit Schrauben befestigt werden.It has repeatedly been found that loudspeakers with a bayonet lock have poorer acoustic properties than loudspeakers with other fastening devices, in particular loudspeakers that are fastened with screws. Speakers with a bayonet lock were therefore not used for high quality speaker systems. Due to the fact that there are low installation costs compared to other speakers with bayonet locks However, there has long been a desire to have loudspeakers with a bayonet lock that have the same acoustic properties with an otherwise identical construction as loudspeakers with other types of fastening, in particular loudspeakers that are fastened with screws.

Der erfindungsgemäße Lautsprecher mit Bajonettverschluß weist außer mehreren Bajonettverschlußnasen am kreisförmigen Befestigungsring noch eine Vorsprungseinrichtung auf, die vom Befestigungsring weiter vorspringt als die Verschlußnasen und sich in radialer Richtung weiter erstreckt als die Verschlußnasen, so daß die Vorsprungseinrichtung zumindest dann die Einführschlitze der Haltevorrichtung nach hinten abdeckt, wenn der Lautsprecher in seiner Befestigungsstellung in der Haltevorrichtung verdeckt ist, und deren vordere Fläche weiter hinten liegt als der hinterste Punkt der Verschlußnase.The loudspeaker with bayonet lock according to the invention has, in addition to several bayonet lock lugs on the circular fastening ring, a projection device which projects further from the fastening ring than the locking lugs and extends further in the radial direction than the locking lugs, so that the projection device at least then covers the insertion slots of the holding device to the rear, if the loudspeaker is hidden in its mounting position in the holding device, and whose front surface lies further back than the rearmost point of the locking lug.

Die so ausgebildete Vorsprungseinrichtung dient dazu, den Einführschlitz in der Haltevorrichtung zu verdecken, der bei herkömmlichen Lautsprechern mit Bajonettverschluß eine akustische Verbindung zwischen den Schallräumen vor und hinter dem Lautsprecher zuläßt. Die Erfinder haben herausgefunden, daß es diese Verbindung ist, die insbesondere bei offenen Lautsprechern zu den beobachteten, oben beschriebenen Verschlechterungen im akustischen Verhalten im Vergleich zu anders befestigten Lautsprechern führten. Durch diese bisher unverschlossenen Einführschlitze kommt es bei Verwendung offener Lautsprecher zu einem sogenannten akustischen Kurzschluß, während es bei Verwendung geschlossener Lautsprecher zu einem akustischen Leck kommt.The projection device designed in this way serves to cover the insertion slot in the holding device, which allows an acoustic connection between the sound spaces in front of and behind the loudspeaker in conventional loudspeakers with a bayonet lock. The inventors have found that it is this connection which, in particular in the case of open loudspeakers, leads to the observed deteriorations in acoustic behavior, as described above, compared to loudspeakers which are fastened differently. These previously unclosed insertion slots result in a so-called acoustic short circuit when using open speakers, while an acoustic leak occurs when using closed speakers.

Besonders kostengünstig ist die Vorsprungseinrichtung dann herstellbar, wenn sie nur aus je einem einzelnen Vorsprung besteht, der in radialer Richtung nur etwas länger ist, als es die Verschlußnasen sind. Diese Ausführungsform benötigt den geringsten Materialaufwand, jedoch ist der Verwender dazu gezwungen, die Haltevorrichtung gerade so auszugestalten, daß bei befestigtem Lautsprecher die einzelnen Vorsprünge gerade jeweils die zugehörigen Einführschlitze abdecken. Ist demgegenüber die Vorsprungseinrichtung als radial umlaufender Vorsprung ausgebildet, ist der Materialaufwand hoch, jedoch muß der Verwender bei der Konstruktion seiner Haltevorrichtung nicht auf Drehrichtung und das Ausmaß der Verdrehung achten, wie sie beim Befestigungsvorgang einzuhalten sind.The projection device can be produced particularly cost-effectively if it consists of only one individual projection, which is only slightly longer in the radial direction than the locking lugs are. This embodiment requires the least amount of material, but is the user forced to design the holding device so that when the speaker is attached, the individual projections just cover the associated insertion slots. If, on the other hand, the projection device is designed as a radially circumferential projection, the material expenditure is high, but the user does not have to pay attention to the direction of rotation and the extent of the rotation as they are to be observed during the fastening process when designing his holding device.

BESCHREIBUNG VON AUSFÜHRUNGSBEISPIELENDESCRIPTION OF EMBODIMENTS

Die in Fig. 1 außer einem offenen Lautsprecher 10 dargestellte Haltevorrichtung 11 besteht aus einer Platte mit einem Haltering 13, dessen Innendurchmesser dem Außendurchmesser eines Befestigungsringes 14 am Lautsprecher 10 entspricht.The holding device 11 shown in FIG. 1 apart from an open loudspeaker 10 consists of a plate with a holding ring 13, the inner diameter of which corresponds to the outer diameter of a fastening ring 14 on the loudspeaker 10.

Am Innenumfang des Halteringes 13 sind 4 Einführschlitze 15 in axialer Richtung mit anschließenden Sicherungsnuten 16 in radialer Richtung vorhanden. Die Schlitzanordnungen, von denen nur zwei in Fig. 1 erkennbar sind, sind unter gegenseitigen Winkeln von 90° angeordnet. Am Befestigungsring 14 des Lautsprechers 10 sind vier Bajonettverschlußnasen 17 unter einem gegenseitigen Winkel von 90° angeordnet. Sie springen so weit vom Befestigungsring 14 vor, daß sie in die Einführschlitze 15 eingeführt und dann verdreht werden können, bis Kuppen 21 der Verschlußnasen 17 in die Sicherungsnuten 16 einrasten.On the inner circumference of the retaining ring 13 there are 4 insertion slots 15 in the axial direction with subsequent securing grooves 16 in the radial direction. The slot arrangements, only two of which can be seen in FIG. 1, are arranged at mutual angles of 90 °. On the mounting ring 14 of the loudspeaker 10, four bayonet locking lugs 17 are arranged at a mutual angle of 90 °. You jump so far from the mounting ring 14 that they can be inserted into the insertion slots 15 and then rotated until crests 21 of the locking lugs 17 snap into the locking grooves 16.

In den insoweit beschriebenen Merkmalen ist der Lautsprecher 10 mit der zugehörigen Haltevorrichtung 11 identisch mit aus dem Stand der Technik bekannten Anordnungen. Die Verschlußnasen 17 und die Verdrehschlitze 16 weisen irgendeine bekannte Gestalt auf, die ein sicheres Halten im verdrehten Zustand gewährt, z. B. sind an den Verschlußnasen 17 Kuppen vorhanden, die in zugehörige Aussparungen in den Verdrehschlitzen einschnappen, wenn der Lautsprecher nach dem Einführen der Verschlußnasen in die Einführschlitze ausreichend weit verdreht ist.In the features described so far, the loudspeaker 10 with the associated holding device 11 is identical to arrangements known from the prior art. The locking tabs 17 and the twist slots 16 have any known shape which ensures secure holding in the twisted state, e.g. B. 17 caps are present on the locking lugs, which snap into associated recesses in the twist slots when the speaker is rotated sufficiently far after inserting the locking lugs into the insertion slots.

Wenn der Lautsprecher 10 in der eben genannten Art im Haltering 13 befestigt ist, sind die Einführschlitze 15 frei, weswegen Schall durch diese Schlitze entlang dem in Fig. 1 an der Haltevorrichtung 11 rechts dargestellten Doppelpfeil 18 vom Raum vor der Haltevorrichtung in den Raum hinter der Haltevorrichtung und umgekehrt dringen könnte, wenn nicht am Befestigungsring vier Vorsprünge 19 vorhanden wären, die gerade so angeordnet sind, daß sie die Einführschlitze 15 nach hinten abdecken, wenn der Lautsprecher 10 in seine Befestigungsstellung verdreht ist. Die Vorsprünge 19 schließen sich also in radialer Richtung entgegen der Drehrichtung an die jeweils benachbarte Verschlußnase 17 an, wie dies aus Fig. 1, insbesondere aber auch aus Fig. 2 erkennbar ist. Dabei liegt die vordere Fläche 20 jedes Vorsprungs 19 weiter hinten als der hinterste Punkt 21 der Verschlußnasen 17. Der Abstand entspricht dem Abstand des hinteren Randes eines Verdrehschlitzes 16 vom hinteren Rand des Halterings 13. Damit die Vorsprünge 19 den jeweils zugehörigen Einführschlitz 15 sicher abdecken, springen sie weiter vom Befestigungsring 14 vor, als dies für die Verschlußnasen 17 gilt.If the speaker 10 is fastened in the above-mentioned manner in the retaining ring 13, the insertion slots 15 are free, which is why sound through these slots along the double arrow 18 shown on the right in FIG. 1 on the holding device 11 from the room in front of the holding device into the room behind Retaining device and vice versa, if there were not four projections 19 on the mounting ring, which are just arranged so that they cover the insertion slots 15 to the rear when the speaker 10 is rotated into its mounting position. The projections 19 thus connect in the radial direction against the direction of rotation to the respectively adjacent locking lug 17, as is the case here Fig. 1, but in particular also from Fig. 2 can be seen. The front surface 20 of each projection 19 lies further back than the rearmost point 21 of the locking lugs 17. The distance corresponds to the distance of the rear edge of a twist slot 16 from the rear edge of the retaining ring 13. So that the projections 19 reliably cover the associated insertion slot 15, jump further from the fastening ring 14 than is the case for the locking lugs 17.

Der Lautsprecher 10 gemäß den Fig. 1 und 2 ist nur für eine einzige Drehrichtung beim Montieren ausgebildet. Soll dem Benutzer die Drehrichtung freigelassen werden, ist ein Aufbau von Vorteil, wie er in Fig. 3 dargestellt ist. Dieser verfügt über zwei Vorsprünge 19 benachbart zu jeder Verschlußnase 17, welche beiden Vorsprünge beim Ausführungsbeispiel um jeweils denselben Winkel in entgegengesetzten Richtungen radial gegenüber der benachbarten Verschlußnase 17 versetzt sind. Bei Benutzung dieser Ausführungsart muß der Verwender jedoch nach wie vor darauf achten, daß seine Haltevorrichtung so ausgeführt wird, daß ein Verdrehen nur um denjenigen Winkel möglich ist, der gewährleistet, daß bei befestigtem Lautsprecher jeweils einer der beiden Vorsprünge 19 bei einer Verschlußnase 17 über dem zugehörigen Einführschlitz 15 liegt.The loudspeaker 10 according to FIGS. 1 and 2 is only designed for a single direction of rotation during assembly. If the direction of rotation is to be left free for the user, a construction as shown in FIG. 3 is advantageous. This has two projections 19 adjacent to each locking nose 17, which two projections in the exemplary embodiment are offset by the same angle in opposite directions radially with respect to the adjacent locking nose 17. When using this embodiment, however, the user must still make sure that his holding device is designed so that rotation is only possible by the angle that ensures that when the speaker is attached, one of the two projections 19 with a locking lug 17 above the associated insertion slot 15 is located.

Ganz in das Belieben des Anwenders gestellt sind Drehrichtung und Ausmaß der Drehung bei Verwendung einer Ausführungsform, wie sie durch Fig. 4 veranschaulicht ist. Hier ist der Vorsprung 19' radial umlaufend ausgebildet.The direction of rotation and the extent of the rotation are entirely at the discretion of the user when using an embodiment as illustrated by FIG. 4. Here, the projection 19 'is radially circumferential.

Neben den dargestellten Ausführungsformen sind noch weitere möglich, z. B. eine solche, bei der ausgehend von der Ausführungsform gemäß Fig. 3 die dort dargestellten beiden Vorsprünge miteinander verbunden sind, so daß ein einzelner Vorsprung vorhanden ist, der sich in radialer Richtung nach beiden Seiten ausgehend von der zugehörigen Verschlußnase gleich weit erstreckt. Weiterhin ist es z. B. möglich, zwischen der Verschlußnase 17 bei der Ausführungsform gemäß Fig. 2 und dem benachbarten Vorsprung 19 keinen radialen Abstand 22 einzuhalten, sondern den Vorsprung 19 schon vor dem Ende der Verschlußnase 17 oder sogar über derselben beginnen zu lassen. Aus Materialersparnisgründen ist es jedoch von Vorteil, jeden Vorsprung 19 so auszubilden, daß er im montierten Zustand des Lautsprechers 10 gerade den zugehörigen Einführschlitz 15 abdeckt. Es wird daher in der Regel ein kleiner radialer Abstand 22 vorhanden sein, der Vorsprung 19 wird nur wenig mehr über die Befestigung 14 überstehen als die Verschlußnase 17 und der Vorsprung 19 wird in radialer Richtung nur wenig breiter sein als die Verschlußnase 17, an deren Breite die Einführschlitze 15 angepaßt sind.In addition to the illustrated embodiments, other are possible, for. B. one in which, starting from the embodiment according to FIG. 3, the two projections shown there are connected to one another, so that there is a single projection which extends in the radial direction towards both Sides extending equally far from the associated locking tab. Furthermore, it is e.g. B. possible to maintain no radial distance 22 between the locking lug 17 in the embodiment according to FIG. 2 and the adjacent projection 19, but rather to let the projection 19 begin before the end of the locking lug 17 or even above the same. For reasons of material savings, however, it is advantageous to design each projection 19 such that it just covers the associated insertion slot 15 in the assembled state of the loudspeaker 10. There will therefore usually be a small radial distance 22, the projection 19 will only protrude a little more than the fastening 14 than the locking lug 17 and the projection 19 will be only slightly wider in the radial direction than the locking lug 17, at its width the insertion slots 15 are adapted.
