Abstract: Systems and methods of driving plate loudspeakers with different parameters based on frequency region in a way similar to typical cone driver crossover networks are described. These systems and methods may be implemented using arrays of independently controlled drivers which allow a designer to emphasize or de-emphasize certain modes in certain frequency bands. Tuning the characteristics of the plate's motion can also affect the acoustical properties in a larger space rather than just at a single location. The systems and methods described herein can grant a designer a degree of control over the characteristics and performance of the plate.

Abstract: A loudspeaker system composed of a flexible panel with an affixed array of force actuators, a signal processing system, and interface electronic circuits is described. The system described is capable of creating a pattern of standing bending waves at any location on the panel and the instantaneous amplitude, velocity, or acceleration of the standing waves can be controlled by an audio signal to create localized acoustic sources at the selected locations in the plane of the panel.
