AB  - A series combination of inductor and resistor is traditionally used to model the blocked electrical impedance of a dynamic moving coil transducer, such as a loudspeaker driver. In practice, semi-inductive behaviour due to eddy currents and ‘skin effect’ in the pole structure as well as transformer coupling between the voice coil and pole piece can be observed, but are not well represented by this simple model. An improved model using only a few additional elements is introduced to overcome these limitations. This improved model is easily incorporated into existing equivalent circuit models. The development of the model is explained and its use is demonstrated. Examples yielding more accurate box response simulations are also shown.
