Patent ID: 8760039

Claim:
A system for reducing vibration in a flexible panel, the system comprising: a diamond-shaped actuator having a piezoelectric wafer portion and an inter-digitated electrode (IDE) positioned with respect to the piezoelectric wafer, wherein the diamond-shaped actuator is configured to generate and transmit a force to the flexible panel in response to a proportional output voltage signal; a point sensor positioned with respect to the diamond-shaped actuator, wherein the point sensor is configured for measuring the vibration at a surface of the flexible panel; and a controller that is electrically connected to the actuator and to the point sensor, wherein the controller receives a vibration signal from the point sensor describing the measured vibration, and is configured for: calculating the proportional output voltage signal using the vibration signal; and transmitting the proportional output voltage signal to the actuator to substantially cancel the vibration at the surface of the flexible panel.
