发明名称 Transducers with improved viscous damping
摘要 A miniature receiver or transducer with improved viscous damping. The receiver may be a moving armature receiver using shearing forces for damping the deflection of the diaphragm. In this receiver, the damping element, which may be a liquid, extend in a direction of the deflection of the armature or diaphragm. Another embodiment relates to a transducer where the damping element engages the diaphragm.
