Resumo
In this work we present preliminary results of the process followed for the adjustment of a numerical model in finite elements of the mechanical behaviour of a pleated loudspeaker, based on the AMT technology (Air Motion Transformer). In this type of transducers, the diaphragm is formed by longitudinal folds. In the internal face of each one of these folds is printed a conductive ribbon. We have obtained firstly the participation factors and the generalized mass from the results of a natural vibration modal analysis. Next, an analysis is realized taking into account the loss factors of the materials, followed by a forced vibration modal analysis.
