In this paper, we propose a way to determine the nonlinear parameters of a loudspeaker system by Simulated Annealing(SA) for Mirror filter. The nonlinear parameters determined by the conventional W. Klippel's method sometimes become very large values or imaginary values, and then we have not obtained the enough performance on compensating nonlinear distortions of a loudspeaker system when Mirror filter is designed by using the parameters. In contrast, the proposed method is a way to measure the spectrum of a loudspeaker system on the displacement of a diaphragm and find the nonlinear parameters by SA so as to approach the spectrum. They are consequently determined with accuracy. We design Mirror filter which uses the nonlinear parameters of a loudspeaker system determined by SA, and examine the effectiveness on compensating nonlinear distortions of a loudspeaker system. Experimental results demonstrate that the levels of nonlinear distortions can be reduced in the range of 5[dB] to 15[dB] compared with before compensation in case of using the nonlinear parameters determined by SA. |
