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.
