发明名称 Planar diaphragm loudspeakers with non-uniform air resistive loading for low frequency modal control
摘要 A loudspeaker, and particularly, a woofer, including a flat diaphragm transducer having at least one stator plate for carrying magnetic elements in close proximity to a low stiffness diaphragm wherein a piston-like motion of the diaphragm is achieved by creating pressure zones adjacent the diaphragm to improve an acoustic coupling and increase acoustic output for a given size of diaphragm by the provision of non-uniformly spaced openings in the at least one stator plate which are selectively spaced to control low frequency diaphragm resonance modes.
