Abstract:
An electroacoustic transducer, including:at least one stator member having an operating surface for positioning adjacent an emitter diaphragm; an emitter diaphragm suspended adjacent to and spaced a sufficient distance from the operating surface of the stator member to enable diaphragm oscillation in response to an applied signal voltage to permit diaphragm movement within at least one emitter section without contacting the operating surface of the stator member; said diaphragm being configured with alternating peaks and valleys extending along a longitudinal dimension of the diaphragm, including an increased stiffness orientation which provides greater directional stiffness along the longitudinal dimension, wherein the alternating a securing structure applied in transverse orientation with respect to the stiffness orientation at the diaphragm with respect to the operating surface of the stator member to secure the diaphragm in a fixed position.
