AB  - The conventional model of a dynamic moving-coil loudspeaker is improved by incorporating a semi-inductor that results from eddy currents and skin effect in the pole pieces. Highly conductive metals such as aluminum, copper, or silver concentric to the voice coil can be treated as a one-turn secondary in a transformer with the primary of the voice coil. This new model produces more accuracy, as illustrated in a simulation of sound pressure frequency response of a woofer in an enclosure. The model is relevant to all electrodynamic transducers.
