Abstract

A mechanism for a speaker assembly utilizing a brace for confining a speaker cone in a particular orientation. The brace is provided with at least first and second feet which append therefrom. At least one of the feet is fastened to a permanent magnet associated with the cone to isolate vibrations originating in the permanent magnet. In this regard, a plate is employed in conjunction with an elastomeric member such that the elastomeric member is interposed the foot and the plate. The elastomeric member is held to the plate and the first foot. The elastomeric member is sized to create a bias for movement of the brace only in a shear direction relative to the plate and the first foot. A fastener is also employed to support the first and second feet to the permanent magnet at predetermined distances from the permanent magnet.

Claims

1. A mechanism for mounting a speaker cone to a permanent magnet adjacent the speaker cone comprising:

a. a brace for confining the speaker cone, said brace including at least first and second feet depending therefrom;

b. fastening means for supporting at least said first foot to the permanent magnet, said fastening means including a plate, an elastomeric member interposed said first foot and said plate, said elastomeric member creating a bias for movement of said first foot in a shear direction relative to said plate, holding means for supporting said elastomeric member to said plate and said first foot, and first and second fasteners for supporting each of said first and second feet directly to the permanent magnet at a predetermined distance therefrom.

2. The mechanism of claim 1 in which said brace includes a quartet of feet appending therefrom.

3. The mechanism of claim 1 in which said holding means for supporting said elastomeric member to said plate and said foot includes one mastic layer interposed said elastomeric member and said plate.

4. The mechanism of claim 3 in which said holding means for supporting said elastomeric member to said plate and said first foot further includes another mastic layer interposed said elastomeric member and said plate.

5. The mechanism of claim 1 in which at least said first foot includes a pad positioned adjacent said elastomeric member.

6. The mechanism of claim 1 which additionally includes stop means for limiting the shear movement of said at least first foot and elastomeric member held thereto relative to said plate.

7. The mechanism of claim 6 in which said stop means includes a rim extending outwardly from said plate toward said first foot.

8. The mechanism of claim 7 in which said stop means further includes a resilient spacer interposed said first foot and said rim of said plate.

9. The mechanism of claim 8 in which said first foot includes a pad, said resilient spacer at least partially surrounding said pad and interposed said pad and said rim of said spacer.

10. The mechanism of claim 1 in which said fastening means further supports said second foot to the permanent magnet and where said fastening means plate is a first plate, said elastomeric member is a first elastomeric member said holding means is first a holding means, and said fastener is a first fastener, and further includes a second plate, a second elastomeric member interposed said second foot and said second plate said second elastomeric member creating a bias for movement in a shear direction between said second plate and said second foot, second holding means for supporting said second elastomeric member to said second plate and said second foot, and a second fastener for supporting said second foot to the permanent magnet at a predetermined distance.
