Appears especially important to the speaker nonlinear distortion mechanism analysis. Regarding the different frequency band, the micro speaker nonlinear distortion's primary factor is not same: The membrane non-linearity is the speaker in the intermediate frequency section main nonlinear distortion factor, has provided the rationale to this distorted factor's analysis for the speaker membrane geometrical shape design innovation; The suspension system force of restitution, the electromagnetic coupling factor, the magnetic resistance strength's non-linearity is the speaker in the low frequency band main nonlinear distortion factor, these aspect's research for the material development, the magnetic circuit electric circuit's design provides certain rationale. Master period, mainly has studied woofer's low frequency subharmonics distortion mechanism, in the reading paper's foundation, has mainly done the following work: 1. uses Klippel Analyzer System the system survey to obtain speaker's related non-linear factor which this article studies.
