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.
Claims18
A sound reproducing device comprising:
- a housing;
- an acoustic diaphragm;
- support means for supporting said acoustic diaphragm for substantially free longitudinal movement relative to said housing while maintaining said acoustic diaphragm in a predetermined lateral position relative to said housing, said support means comprising corrugated compliant coupling means having a lateral cross-sectional shape which is noncircular;
- and
- drive means for providing relative longitudinal movement between said acoustic diaphragm and said housing.
In a sound reproducing device having a housing, an acoustic diaphragm, support means for supporting said acoustic diaphragm for substantially free longitudinal movement relative to said housing while maintaining said acoustic diaphragm in a predetermined laterial position relative to said housing, and means for driving the acoustic diaphragm longitudinally relative to said housing, the improvement comprising said support means comprising a corrugated compliant coupling having a noncircular lateral cross-sectional shape.
