Abstract: In the pre-design phase of a loudspeaker, rapid prediction of the loudspeaker thermal behavior is crucial. Voice coil (VC) temperature is not only influenced by the magnetic circuit materials and geometry, but also by thermal dissipation due to other speaker components e.g., the spider. The aim of this study is to develop a thermal model of the loudspeaker magnetic circuit that provides fast predictions of the VC temperature accounting for convective dissipation due to spider movement. An empirical method to evaluate the spider air permeability was presented and the related effects were implemented in the model. Life tests were performed on different loudspeakers to verify the accuracy of model results. Differences between predicted and measured VC temperatures were acceptable, suggesting possible application to the pre-design phase as the model can provide fast predictions without requiring high-performance hardware.
