Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Luftfilter der eingangs genannten Art bzw. für eine damit ausgestattete Frischluftanlage eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie einen relativ hohen Integrationsgrad aufweist, dabei einen relativ kompakten Aufbau besitzt und insbesondere preiswert herstellbar ist.The The present invention addresses the problem of for an air filter of the type mentioned or for a fresh air system equipped therewith an improved embodiment particular distinguished by the fact that they have a relatively high degree of integration, while a relatively compact Structure has and in particular is inexpensive to produce.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the objects of the independent claims. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, das Luftfilter mit einem Lautsprecher auszustatten, der beispielsweise ein Bestandteil einer Schallmodulationseinrichtung sein kann. Der Lautsprecher besitzt eine Lautsprechermembran, die mit einem elektromagnetischen Aktuator betätigbar ist. Beim erfindungsgemäßen Luftfilter ist die Lautsprechermembran integral mit einer der Gehäuseschalen spritzgeformt, während ein Lautsprechergehäuse an besagte Gehäuseschale angebaut ist.The Invention is based on the general idea, the air filter with To equip a speaker, for example, a component a sound modulation device may be. The speaker has a loudspeaker diaphragm with an electromagnetic actuator is operable. When inventive Air filter, the speaker diaphragm is injection molded integrally with one of the housing shells, while a speaker housing to said housing shell is grown.
Durch die bauliche Zusammenfassung des Luftfilters mit einem Lautsprecher erhält das Luftfilter eine zusätzliche Funktionalität. Insbesondere kann es für eine aktive Schallmodulationseinrichtung verwendet werden. Da die Lautsprechermembran integral mit einer der Gehäuseschalen des Filtergehäuses spritzgeformt ist, reduziert sich der Herstellungsaufwand, wobei gleichzeitig eine kompakte Bauweise realisierbar ist.By the structural summary of the air filter with a loudspeaker the air filter receives additional functionality. In particular, it may be for an active sound modulation device be used. Because the speaker membrane is integral with a the housing shells of the filter housing injection molded is, the production cost is reduced, while at the same time a compact design is feasible.
Für die Betätigung der Lautsprechermembran kann der Aktuator eine elektromagnetische Spule aufweisen, die mit einem an der Lautsprechermembran befestigten weichmagnetischen Anker zusammenwirkt. Entsprechend einer vorteilhaften Ausführungsform kann die Lautsprechermembran eine damit integral spritzgeformte Ankeraufnahme zum Festlegen des Ankers auf weisen. Hierdurch wird der Integrationsgrad weiter erhöht, was die Herstellungskosten senkt.For the actuation of the speaker diaphragm may be the actuator have an electromagnetic coil with one on the speaker membrane attached soft magnetic anchor cooperates. Corresponding In an advantageous embodiment, the speaker diaphragm an integrally injection molded anchor receptacle for defining the Anchor on wise. This further increases the degree of integration, which lowers the manufacturing costs.
Der Integrationsgrad lässt sich entsprechend einer vorteilhaften Ausführungsform weiter steigern, wenn zumindest eine der Gehäuseschalen integral mit einer Mikrofonaufnahme spritzgeformt ist, mit deren Hilfe ein Mikrofon an der jeweiligen Gehäuseschale festlegbar ist. Alternativ kann zumindest eine der Gehäuseschalen integral mit einem Gehäuseteil eines Mikrofons spritzgeformt sein. Ein derartiges Mikrofon kann insbesondere ein Bestandteil einer Schallmodulationseinrichtung bilden.Of the Degree of integration can be according to an advantageous Embodiment further increase, if at least one of Housing shells integrally molded with a microphone holder is, with the help of a microphone on the respective housing shell is determinable. Alternatively, at least one of the housing shells integrally injection molded with a housing part of a microphone be. Such a microphone can in particular be a component form a sound modulation device.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Further important features and advantages of the invention will become apparent from the Subclaims, from the drawings and from the associated Description of the figures with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
