<p>A loudspeaker cone assembly having a generally conical speaker cone body (12) and an annular flexible suspension rim (14). The suspension rim (14) may include an annular integral gasket (20), and is formed from a plastic foam which may be deposited into an annular channel in a female mold (30) cooperable with a male die to define a substantially closed channel. The foam is expanded and cured so that the resulting annular rim and integral gasket have high density closed-cell outer skin surfaces on opposite sides of a low density closed-cell inner core. The suspension rim of the loudspeaker cone assembly may be secured to a support basket for mounting within a speaker cabinet. The annular gasket provides an improved apearance and may serve as a mounting gasket and shock absorber.</p> |
