  "claims": [
    "1. A loudspeaker fixture for mounting a loudspeaker to the rear of a loudspeaker baffle by means of a clamping plate which engages with the fixing flange of the loudspeaker and which does not obstruct the loudspeaker aperture, characterized in that the clamping plate consists of two parts which can be pivoted relative to each other, and one of which is secured to the loudspeaker chassis, and that insertion hooks have been provided near those edges of the clamping plate parts which face away from the hinge, by means of which hooks said edges can be attached to the edges of the loudspeaker aperture, and that the axial distance between the hooks is slightly smaller than the distance between the associated clamping plate edges and the edges of the loudspeaker aperture respectively, so that when the bent clamping plate is depressed into the plane of the loudspeaker baffle the entire plate is compressed axially between the hooks, thus securing the loudspeaker.",
    "2. Loudspeaker fixture is claimed in claim 1, characterized in that the hooks are mounted on the edges of the clamping plate parts facing away from the hinge in such a way that their openings face the edge of the loudspeaker aperture.",
    "3. Loudspeaker fixture as claimed in claim 1, characterized in that a latching spring has been provided at the edge of the pivoted clamping plate part facing away from the hinge, which spring snaps over the loudspeaker chassis when the clamping plate is depressed.",
    "4. Loudspeaker fixture as claimed in claim 1, characterized in that the hinge between the clamping plate parts which can be pivoted relative to each other is constituted by a film hinge formed by a groove in the clamping plate.",
    "5. A loudspeaker fixture as claimed in claim 1, characterized in that the hinge extends in the direction of the minor axis of the ellipse in the case of an oval loudspeaker.",
    "6. A fixture for mounting a loudspeaker to a loudspeaker baffle frame which has defined therein an aperture having sides and end edges and a predetermined length dimension between said end edges, the fixture comprising a clamping plate formed of first and second parts with a pivot joint between them and first and second ends of said parts remote from said joint, one of said plate parts adapted to having the loudspeaker securable thereto, said plate parts being pivotable between a first V-shape orientation with length between said ends being less than said length of the aperture, and a second generally flat orientation with length between said ends being greater than in said first orientation, and engaging means for engaging each of said ends to one of said end edges of the aperture, whereby when said loudspeaker is secured to one of said plate parts and said parts are pivoted to said first orientation, the speaker is mountable to said baffle by engaging via said engaging means the first plate part end to one of said end edges of the aperture, pivoting said parts to said second orientation, and then engaging the second plate part end to the remaining end edge of the aperture.",
    "7. A fixture according to claim 6 wherein said engaging means comprises a hook on each of said plate part remote ends for engaging one of said end edges of the aperture.",
    "8. A fixture according to claim 6 wherein said engaging means comprises a hook on each end edge of the aperture for engaging one of said plate part ends.",
    "9. A fixture according to claim 6 further comprising securing means for releasably securing said loudspeaker to said second plate part when saiD parts are in said second orientation.",
    "10. A fixture according to claim 9 wherein said securing means is a spring on said second plate part for engaging said loudspeaker."

Trifari 5 7 ABSTRACT A loudspeaker fixture for mounting a loudspeaker to a baffle by means of a clamping plate consisting of two hinged parts, one of which engages the loudspeaker, while not obstructing the loudspeaker aperture. 10 Claims, 2 Drawing Figures LOUDSPEAKER FIXTURE BACKGROUND OF THE INVENTION The invention relates to a loudspeaker fixture for mounting a loudspeaker to the rear of a loudspeaker baffle by means of a clamping plate which engages a fixing flange of the loudspeaker and which does not obstruct the loudspeaker aperture. Particularly with motor cars rear mounting of loudspeakers is of great significance, because the loudspeakers are mounted in different places behind the dashboard of the vehicle from the rear. Generally speaking, no screws should extend through the loudspeaker chassis and the loudspeaker baffle to the front of the dashboard; nor is it acceptable to secure the loudspeaker by means of screws from the front of the instrument board.\n\nA known method is to attach the flange of the loudspeaker chassis to a rubber plate, which in turn is cemented to the loudspeaker baffle from the rear of the dashboard.",
