Current-driven loudspeakers have been studied for a long time because they are in great demand by discriminating audiophiles. The latest market research provides clear motivation for producing adequate innovative designs and simple theoretical solutions to address the nonlinear properties of these loudspeakers. Thus, the aim of this paper is to present a compact analytical approach to assess the harmonic distortion that deteriorates the audio quality of electrodynamic loudspeakers, while separately considering the effect of varying the primary respective parameters. Taylor polynomials are conveniently used to derive simple expressions for the first five harmonic distortion lines of the entire spectrum: the significance of each parameter under consideration is rendered transparent using this methodology. This analytical approach is validated by performing a numerical analysis using Simulink software and can easily be implemented using a standard spreadsheet application. We also note that the acceleration of the diaphragm is referenced to the acceleration due to gravity in this study.
