Abstract: Systems and methods are provided for evaluating a device design to reduce audio speaker generated vibrational energy transfer between adjoining components of a device. The method performs a system-level modal analysis on the design to extract a natural frequency and a mode shape and thereafter create an analysis monitoring point on the design between two adjacent components defining a relative distance. Simulation inputs are fed into a linear dynamics finite element analysis (FEA) solver to solve system equations for a relative displacement of the two adjacent components at the analysis monitoring point, and if the solved relative displacement causes the relative distance to be equal to or less than a zero-relative distance value, then the device design is modified by at least one value of an element from one of the two adjacent components.
