Low Frequency Nonlinear Model for Loudspeaker Transducers

In this paper a nonlinear loudspeaker transducer model and its solution are presented. A simple and effective iteration procedure to obtain the solution of the nonlinear equation is proposed. This procedure is a powerful tool for determination of a periodic solution of a non-linear equation of motion. Further, the sound pressure of fundamental, second order, and third order harmonic distortion are also calculated. The solutions obtained using the present iteration method can give the directions to how to lower the second and third harmonics.
