Theoretical and Experimental Analysis of Nonlinear Parametric Vibrations of an Electrodynamical Loudspeaker Diaphragm

Nonlinear parametric vibrations of a loudspeaker diaphragm which cause the onset of subharmonics in the radiated signal are studied. As experiments show parametric vibrations appear in the specific frequency regions and under the certain "critical" value of the driving force and they are subjectively audible as coloration of sound. The results of experiments which have been carried out for the lots of manufactured loudspeakers are presented. The character of parametric vibrations and the influence of constructive loudspeaker parameters on it has been examined. Mathematical model based on the system of nonlinear differential equations has been constructed. Using the developed asymptotic method and software the frequency bandwidth and amplitudes of the loudspeaker diaphragm parametric vibrations have been calculated.
