This is the second in a series of papers on the details of loudspeaker design using multiphysical computer aided engineering simulation methods. In this paper the simulation methodology for accurately modeling the structural dynamics of loudspeaker’s vibration systems will be presented. Primarily, the calculation of stiffness, or its inverse the compliance in the virtual world, will be demonstrated. Furthermore, the predictive simulation of complex vibration patterns, e.g., rocking or break-up, will be shown. Finally the simulation of coupling effects to the motor system will be discussed. Results will be presented, correlating the simulated model results to the measured physical parameters. From that, the important aspects of the modeling that determine its accuracy will be discussed.
