Abstract

In a broadcast receiving system for stereo reproduction in vehicles with at least two stereo channels and with at least one woofer common to both channels, this woofer - or a plurality thereof - is disposed outside the passenger compartment, preferably in the boot and the sound vibrations transmitted by it are carried into the passenger compartment via a channel provided in the vehicle, preferably a ventilation channel of the passenger compartment.

Description

Patentansprüche: 1. Rundfunkempfangsanlage für stereofonische Wiedergabe in Fahrzeugen, insbesondere Kraftfahrzeugen, mit wenigstens zwei Stereokanälen und mit wenigstens einem Tieftonlautsprecher, dessen Eingangssignale aus den über die Stereokanäle laufenden Signalen mittels Frequenzweichen ausgefiltert werden, d ad u rc h g ek en n zei c h n et, daß der oder die Tieftonlautsprecher (8) außerhalb des Fahrgastraumes (2) so angeordnet ist oder sind, daß die von ihm/ihnen erzeugten Schallschwingungen über einen im Fahrzeug vorhandenen Kanal (6) bzw. ein Kanalsystem, welcher/welches für den Anbau des/ der Lautsprecher (8) errtsprechende, der Schalleinspeisung dienende Öffnungen (9) erhält, in den Fahrgastraum (2) geleitet werden. Claims: 1. Radio receiving system for stereophonic reproduction in vehicles, in particular motor vehicles, with at least two stereo channels and with at least one woofer whose input signals from the Signals running on stereo channels are filtered out by means of crossovers, d ad u rc h g ek en n sign that the woofer or speakers (8) are outside of the passenger compartment (2) is or are arranged so that the generated by him / them Sound vibrations through a duct (6) or a duct system in the vehicle, which one is appropriate for the installation of the loudspeaker (8), the sound feed Serving openings (9) are passed into the passenger compartment (2).

2. Rundfunkempfangsanlage nach Anspruch 1, dadurch gekennzeichnet, daß der Tieftonlautsprecher im Kofferraum (3) derart angeordnet ist, daß die von ihm erzeugten Schallschwingungen über die Entlüftungskanäle (7) in den Fahrgastraum (2) geleitet werden. 2. Radio receiving system according to claim 1, characterized in that that the woofer in the trunk (3) is arranged such that the of it generated sound vibrations through the ventilation ducts (7) into the passenger compartment (2) be directed.

Die Erfindung bezieht sich auf eine Rundfunkempfangsanlage nach dem Oberbegriff des Patentanspruches 1. The invention relates to a radio receiving system according to the Preamble of claim 1.

Eine derartige Rundfunkempfangsanlage ist aus der DE-OS 30 28 610 bekannt, bei welcher außer den jedem Kanal zugeordneten Lautsprechern für die zusätzliche Wiedergabe von tiefen Frequenzen ein gemeinsamer Tieftonlautsprecher vorgesehen ist, der auf der Heckablage des Fahrzeuges angeordnet ist und über eine Öffnung mit dem Kofferraum verbunden ist, der hier sozusagen als Resonanzraum wirkt. Such a radio receiving system is from DE-OS 30 28 610 known in which besides the speakers assigned to each channel for the additional A common woofer is provided for reproduction of low frequencies which is arranged on the rear parcel shelf of the vehicle and has an opening is connected to the trunk, which acts here as a resonance space, so to speak.

Die Heckablage wird aber oft zur Unterbringung des Verbandkastens, von den einzelnen Stereokanälen zugeordneten Lautsprechern, Kopfstützen usw. benutzt, so daß für größere Lautsprecher, die für eine Tieftonwiedergabe geeignet sind, kein Platz vorhanden ist. The rear shelf is often used to accommodate the first-aid kit, speakers, headrests, etc. assigned to the individual stereo channels are used, so that for larger speakers that are suitable for bass reproduction, no Space is available.

Es ist deshalb Aufgabe der Erfindung, für den oder die Tieftonlautsprecher eine derartige Anordnung zu schaffen, daß einerseits die Heckablage für anderweitige Verwendung frei bleibt, daß aber andererseits nicht auf kleine Lautsprecher zurückgegriffen werden muß. It is therefore the object of the invention for the woofer or speakers to create such an arrangement that on the one hand the rear shelf for other Usage remains free, but on the other hand no small loudspeakers are used must become.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruches 1 genannten Merkmale gelöst. According to the invention, this object is achieved by the characterizing features of the patent claim 1 mentioned features solved.

Einem derartigen Aufbau kommt zugute, daß das menschliche Ohr die Schallquelle von tiefen Frequenzen unterhalb etwa 200 Hz, die sich nahezu kugelförmig ausbreiten, nicht orten kann. Bei einem Einbau im Kofferraum bleibt der Vorteil, diesen als Resonanzraum zu verwenden, erhalten. Ein zusätzlicher Vorteil ist, daß die Öffnungen zwischen Fahrgastraum und Entlüftungskanal bereits vorhanden und meistens so angeordnet sind, daß sie von den Insassen gar nicht wahrgenommen werden. Such a structure benefits from the fact that the human ear can Sound source of low frequencies below about 200 Hz, which is almost spherical spread, cannot locate. When installing in the trunk, the advantage remains to use this as a resonance space. An added benefit is that the openings between the passenger compartment and the ventilation duct already exist and mostly are arranged in such a way that they are not even perceived by the occupants.

In der Zeichnung ist ein Längsschnitt durch ein Kraftfahrzeug 1 im interessierenden Bereich zwischen Fahrgastraum 2 und Kofferraum 3 dargestellt. Unter der Heckablage 4, strichliert eingezeichnet, sind links und rechts außen zwei kleine Hecklautsprecher 5 für den linken und rechten Stereokanal angeordnet, zwischen denen sich ein nicht dargestellter Verbandkasten befinden kann. Hinter dieser Anordnung - in Fahrtrichtung betrachtet - erstreckt sich im wesentlichen über die ganze Breite der Heckablage ein Entlüftungskanal 6 mit Öffnungen 7 zum Fahrgastraum 2. The drawing shows a longitudinal section through a motor vehicle 1 in Area of interest between passenger compartment 2 and trunk 3 is shown. Under of the rear shelf 4, shown in dashed lines, are two small ones on the left and right on the outside Rear speakers 5 arranged for the left and right stereo channel, between which a first aid kit, not shown, can be located. Behind this arrangement - viewed in the direction of travel - extends essentially over the entire width the rear parcel shelf has a ventilation channel 6 with openings 7 to the passenger compartment 2.

Claims (1)

Unterhalb dieses Entlüftungskanals 6 sind im Kofferraum 3 ein oder mehrere Tieftonlautsprecher 8 mit nach oben gerichteten Schalltrichtern angeordnet, welche die von ihnen übertragenen tiefen Töne über Öffnungen 9 im Entlüftungskanal 6 in den Entlüftungskanal und über die Öffnungen 7 in den Fahrgastraum 2 übertragen. Der Kofferraum 3 kann dabei in an sich bekannter Weise als Resonanzraum wirken. Below this ventilation duct 6 are in the trunk 3 or several woofers 8 arranged with horns pointing upwards, which the low tones transmitted by them through openings 9 in the ventilation duct 6 transferred into the ventilation duct and via the openings 7 into the passenger compartment 2. The trunk 3 can act as a resonance space in a manner known per se.
