ABSTRACT:
A low voltage bender piezo-actuator with multiple, same size piezo layers (11, 12) separated by thin electrically conductive strips (14) and adapted to be affixed to a rigid, vibration transmitting plate (10) to produce noise counter vibrations to prevent noise from passing through the plate.
