Vibration of loudspeaker’s membrane was analyzed in the regime of comparatively low driving currents (I < 120 mA) and in terms of mass nonlinearity Meff and intrinsic friction RM. Later contributes to damping term of the differential equation of motion and depends on the elongation of vibration. Independent measurements of flexural strength of the membrane were performed and correlated to experimental observations of the vibrating system. Experiments were also performed with membrane additionally reinforced by application of materials with higher Young module.
