Abstract
There is disclosed a method of designing a panel assembly for a vibratory panel device, the assembly comprising a panel which supports vibrations and two or more transducers coupled to the panel to transmit vibrations to or receive vibrations from the panel. The method comprises: obtaining the number of transducers to be used in the assembly and their relative positions; obtaining relationships between drive signals to be applied to the respective transducers to provide a desired effect; determining an optimization criterion for the assembly that depends on the obtained relationships; and determining one or more parameters for the respective transducers that satisfy the optimization criterion. The one or more parameters may be selected from amplitudes of drive signals, spacing, activity, area, position, shape, dimension.
