Sažetak
Vibration of the loudspeaker’ s membrane was analyzed in the regime of comparatively low driving currents (I0 < 100 mA) in terms of mass nonlinearity Meff and intrinsic friction RM. The latter contributes to the damping term of the differential equation of motion and depends on the elongation of vibration. RM is the sum of intrinsic friction Ri of the membrane and friction Rv coming from air viscosity on its surface. Independent measurements of flexural strength of the membrane were performed and correlated to experimental observations of the vibrating system. Experiments were also performed with membranes additionally reinforced by application of materials with higher Young modules.
