ABSTRACT:
An improved sound reproducing device which includes a housing, an acoustic diaphragm and drive means for driving the acoustic diaphragm. Corrugated compliant coupling means is provided for supporting the acoustic diaphragm with respect to the housing in a predetermined lateral position for longitudinal movement relative thereto. The compliant coupling means has a lateral cross-sectional shape which is noncircular so that the acoustic diaphragm is centered in a predetermined lateral position but which allows freedom of movement in the longitudinal direction. The drive means provides the relative longitudinal movement between the acoustic diaphragm and the housing. In a preferred embodiment, the corrugated compliant coupling has a rectangular cross-sectional shape.
