Abstract
An application for adaptive nonlinear filters, adaptive linearization of a loudspeaker, is presented. An adaptive predistortion linearization scheme is used for linearizing a loudspeaker. A model of a direct radiator loudspeaker is developed and studied which takes into account two principal sources of nonlinear distortions: nonlinearity in the suspension system and inhomogeneity in the flux density. Based on this model, simulations of the proposed method were performed. The results show that nonlinear distortions of a loudspeaker can be reduced significantly.Keywords
