Abstract
Diaphragms of planar magnetic transducers having electrical conductor runs applied thereto are deformed to create lines of flexation such as by knurling, pressing, embossing or the like prior to being placed under tension within a support frame so as to reduce loss of diaphragm tension and thereby control resonance modes along active surface areas of the diaphragm when electrical energy is applied through the conductor runs.
