T12 - LOUDSPEAKER NONLINEARITIES—CAUSES, PARAMETERS, SYMPTOMS

Presenter:
Wolfgang Klippel, Klippel GmbH

Abstract:
This tutorial addresses the relationship between nonlinear distortion measurements and nonlinearities that are the physical causes for signal distortion in loudspeakers, headphones, micro-speakers, and other transducers. Using simulation techniques characteristic symptoms are identified for each nonlinearity and presented systematically in a guide for loudspeaker diagnostics. This information is important for understanding the implications of nonlinear parameters and for performing measurements that describe the loudspeaker more comprehensively. The practical application of the new techniques are demonstrated on practical examples.
