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.
Claims21
1-65. (canceled)
A system comprising:
- a modal crossover network to process a signal into at least a first sub-signal associated with a high frequency band and a second sub-signal associated with a low frequency band;
- and a device, comprising:
- a plate, and
- at least one driver to drive a mode of motion in the plate as a result of the high frequency band.
A system comprising:
- a modal crossover network to process a signal into at least a first sub-signal associated with a high frequency band and a second sub-signal associated with a low frequency band;
- a plate;
- at least one high frequency driver to drive a mode of motion as a result of the high frequency band;
- and
- at least one low frequency driver to drive a mode of motion as a result of the low frequency band,
- wherein the at least one high frequency driver and/or the at least one low frequency driver is in mechanical communication with the plate.
