ABSTRACT:
A compression speaker driver has a relatively stiff, light weight diaphragm 11, including a dome portion and a rim portion around the periphery of the dome portion. The mounting plate 17 has an opening larger than the dome portion of the diaphragm 11, and a ring 31 is laminated to both the diaphragm 11 rim and to the mounting plate 17. Producing a composite compliance which prevents significant radial movement of the dome portion and which distributes the stress of flexing across the width of the compliance.
