Diese Aufgabe wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil des An­ spruchs 1 gelöst. Da das geschlossene Volumen des Hohlraums in Übereinstimmung mit den Eigenschaften des aktiven Schallwandlers festgelegt ist, wird ein hoher Wirkungsgrad bei der Wiedergabe insbesondere tiefer Töne mit niedriger Frequenz erzielt. Dabei ist eine einfache und schnelle Montage in einem Fahrzeuginnenraum möglich, weil der Hohlraum ein Raum ist, der in einem Motorfahrzeug an sich bereits vorhanden ist.This object is achieved by the features in the characterizing part of the claim 1 solved. Since the closed volume of the cavity in accordance with the Characteristics of the active sound transducer is set, a high efficiency in the Playback especially low-pitched low-frequency sounds achieved. It's a simple one and quick assembly in a vehicle interior possible because the cavity is a space is that is already present in a motor vehicle in itself.

Dadurch, dass die in einem Kraftfahrzeug ohnehin vorhandenen Hohlräume in Konsolen, Hutablagen und dergleichen direkt genutzt werden und für die Unterbringung des Lautspre­ chersystems keine zusätzlichen Kästen oder Gehäuse erforderlich sind, wird insgesamt eine Gewichtsersparnis erreicht verbunden mit einer Verringerung der Bauteile und Herstellungs­ kosten.Because the cavities already present in a motor vehicle in consoles, Hat racks and the like are used directly and for the accommodation of the speaker chersystems no additional boxes or housings are required, a total of one Weight savings achieved with a reduction in components and manufacturing costs.

Nachfolgend wird die Erfindung anhand der Zeichnungen beispielhaft erläutert. Es zeigen:The invention will be explained by way of example with reference to the drawings. Show it:

Fig. 1 eine schematische Schnittansicht verschiedener Kombinationen von aktiven Lautspre­ chern mit passiven Elementen, eingesetzt in Hohlräume unterschiedlicher Formen, wie sie beispielsweise in Kraftfahrzeugen vorliegen, und Fig. 1 is a schematic sectional view of various combinations of active loudspeakers with passive elements, used in cavities of different shapes, such as those in motor vehicles, and

Fig. 2 eine vergrößerte Schnittansicht einer Ausführungsform eines passiven Elementes. Fig. 2 is an enlarged sectional view of an embodiment of a passive element.

Das Lautsprechersystem aus aktiven Lautsprechern (unter "Lautsprecher" werden vorliegend unter anderem auch deren Schallwandler verstanden, die aktiv angetrieben sind) und passiven Elementen, worunter Membranen zu verstehen sind, deren Masse derart kalibriert ist, dass sie sich in Phase mit dem aktiven Schallwandler bewegt, wird anhand von Ausführungsformen im Zusammenhang mit Hohlräumen erläutert, die in Kraftfahrzeugen zur Verfügung stehen, in denen das notwendige geschlossene Luftvolumen 1 von Teil- oder Gesamtkonfigurationen von bei der Fertigung entstehenden Räumen genutzt wird, die üblicherweise im Inneren von Türen bzw. Türverkleidungen, Hutablagen und dergleichen Fahrzeugbestandteilen vorhanden sind. Als Alternative und abhängig von den jeweiligen Fahrzeugtypen kann das geschlossene Volumen 1 eines Hohlraums 2 schon bei der Herstellung von Fahrzeugteilen berücksichtigt und ausgebildet werden. Es werden Öffnungen 4 für Lautsprecher 6 und passive Membranen 7 in inneren Tragstrukturen 3 des Fahrzeugaufbaus ausgebildet. Die Öffnungen 4 sind abge­ schlossen und ihre Oberflächen sind in Richtung zur Innenseite der Fahrzeuge durch poröse Abdeckungen geschützt. Die Lautsprecher 6 sind koaxial in die entsprechenden Öffnungen 4 mittels herkömmlicher Befestigungsmittel eingesetzt. Die passiven Membranen 7 hingegen sind mit den Tragstrukturen 3 durch am Umfang des passiven Elementes 7 angeordnete Ein­ griffselemente 8, beispielsweise durch einen ringförmigen Rahmen 8, verbunden, der eine zentrale Masse 9 mittels elastischer dämpfender Elemente bzw. Zentrierzwischenelemente 10 trägt. Die zentralen Massen bzw. die passiven Strahler 9 werden aus gestanzten Flächenele­ menten gewonnen, die aus demselben Material wie die Tragstrukturen bestehen, und die ggfs. mit zusätzlichen Kalibrier- oder mechanischen Anpassungsmassen 11 verbunden sind, um das exakt berechnete Gewicht entsprechend den Lautsprechern 6 zu erzielen, welche sie ansteu­ ern.The loudspeaker system of active loudspeakers ("loudspeakers" are understood in the present case to include, among other things, their sound transducers which are actively driven) and passive elements, by which are meant membranes whose mass is calibrated in such a way that it moves in phase with the active sound transducer , will be explained with reference to embodiments in connection with cavities available in motor vehicles in which the necessary closed air volume 1 of partial or total configurations of manufacturing resulting spaces is used, usually inside of doors or door panels, parcel shelves and the like vehicle components are present. As an alternative and depending on the respective vehicle types, the closed volume 1 of a cavity 2 can already be taken into account and formed during the production of vehicle parts. There are openings 4 for speakers 6 and passive membranes 7 formed in inner support structures 3 of the vehicle body. The openings 4 are closed abge and their surfaces are protected towards the inside of the vehicles by porous covers. The speakers 6 are coaxially inserted into the corresponding openings 4 by means of conventional fastening means. The passive membranes 7, however, are connected to the support structures 3 by arranged on the circumference of the passive element 7 A handle elements 8 , for example by an annular frame 8 , which carries a central mass 9 by means of elastic damping elements or centering intermediate elements 10 . The central masses or the passive radiators 9 are obtained from stamped Flächenele elements, which consist of the same material as the support structures, and if necessary, with additional calibration or mechanical adjustment masses 11 are connected to the exact calculated weight corresponding to the speakers 6 achieve which they drive.

Mit 12 ist in Fig. 1 ein Gehäuse durch gestrichelte Linien angedeutet, das auch zur Ausbil­ dung eines Hohlraums 2 verwendet werden kann.With 12 a housing indicated by dashed lines in Fig. 1, which can also be used for Ausbil tion of a cavity 2 .

Die passiven Elemente 7 können auch mit anderen Strukturen verwirklicht werden, so lange ihre Masse derart ausgelegt ist, dass sie sich in Phase mit den aktiven Schallwandlern 6 eines Lautsprechers bewegen.The passive elements 7 can also be realized with other structures as long as their mass is designed to move in phase with the active transducers 6 of a loudspeaker.
