AES Convention 137 · Paper 9162 · October 2014

Abstract

Adverse effects in transducer motors produced by the nonlinear force factor on performance of loudspeakers are well understood. Nonlinear effects produced by dependence of the voice coil inductance and resistance on the coil’s position and on the current are less obvious. Previous work of the authors showed the nonlinear behavior of the voice coil inductive component presented as a function of the voice coil position, which was obtained by FEA simulation tools. This work is an attempt to obtain variation of the aforementioned parameters experimentally as functions of the voice coil position, current, and frequency.
