Non-vibrational oscillating blade piezoelectric blower

摘要

A non-vibrational oscillating blade piezoelectric blower is disclosed, including: a piezoelectric bender and means for supporting the piezoelectric bender at its inertial nodes. Weights may be attached to the bender to control the location of the inertial nodes. Flexible blades may be attached to the bender at various locations and with their planes in various orientations. The blower according to this invention may also consist of two benders oscillating 180 degrees out of phase to further minimize vibration and noise.
