This work analyses some of the issues related with small size direct radiation loudspeakers design with the main goal of achieving high SPL (Sound Pressure Level). In order to reach it, large diaphragm displacements are needed. Structural dynamic behaviour of the moving assembly must be emphasized. With the aid of a numerical model implemented with finite elements, it is possible to quantify the influence of changing the number of folds in the suspension (spider), the distance between spiders and the effect of destabilizing forces inherent to the speaker construction. Numerical model predictions are compared with experimental results having as reference a six inch loudspeaker development.
