Speaker system for radiating acoustic energy into a cabin of a motor vehicle

DETAILED DESCRIPTION It is, accordingly, an object of the present invention to provide an improved speaker system which is readily fixed by a rigid connection into a limited space within a motor vehicle cabin, such as a rear window shelf, typically where there is minimal space adjacent the rear windshield.
In accordance with one aspect of the present invention, the speaker system for radiating acoustic energy into a cabin of a motor vehicle comprises a support panel such as a rear window shelf fixed to the motor vehicle.
The support panel defines a part of the cabin and has a shelf aperture.
A base-plate member is provided which is fixed to the vehicle body from outside the cabin with respect the support panel and communicates with the cabin by way of the shelf aperture.
A loudspeaker unit is provided having a front face for radiating acoustic energy and a back face fastened on a speaker frame which in turn is secured to a speaker support such as an enclosure box.
The speaker support includes a radiating opening confronting the front face of the loudspeaker unit and a rear opening located opposite to the radiating opening.
The rear opening has a larger dimension than the shelf aperture.
An edge portion of the rear opening abuts the support panel so that the rear opening confronts the shelf aperture.
Finally, a connecting means is provided for connecting the speaker frame and the base member so as to draw the speaker frame toward the base member.
