Abstract

An equalization method is presented for sound sources rendered by eigenmode superposition on flat-panel audio displays. A filter is designed to provide a constant mechanical acceleration for each localized source region at all frequencies below the spatial aliasing frequency of the actuator array used to excite the panel’s bending modes. Within this bandwidth, the vibration profile of the source remains consistent with the application of the equalization filter, preserving any spatial information conveyed to the listener from the source position. Directivity simulations and measurements show that these localized source regions do not exhibit the irregular directivity characteristic of single and multi-actuator distributed mode loudspeakers, but instead exhibit radiation characteristics similar to conventional piston loudspeakers within the array bandwidth.
