| Abstract: | Based on the analysis of the origin of the nonlinear distortion of a loudspeaker, a new method is designed to measure the displacement of the loudspeaker. It is demonstrated by a large number of data that concerning the structure of the loudspeaker the mechanical property of the center suspension has important effect on the nonlinear distortion of the loudspeaker, and hence the study of the center suspension may be a new topic. |
