| 主权项 | 1. An electro-dynamic transducer including: a main magnetic circuit defining an air gap, a moving part comprising a dome shaped diaphragm fixed to a movable coil diving into the air gap; a support to which the moving part is suspended; a suspension linking the moving part and the support; wherein the support at least partly extends in an inner volume inside the moving part, wherein the suspension is fixed, by an outer periphery, to an inner face of the moving part, and wherein the suspension is made of an acoustically non emitting material, and wherein the suspension has in section a substantially polygonal shape and has an outer peripheral edge of frusto-conical shape through which the suspension is fixed to an inner face of the diaphragm. | ||
