Abstract
A vibrational fluid mover assembly having an active damping mechanism is disclosed. The vibrational fluid mover assembly includes a vibrational fluid mover having a first plate, a second plate spaced apart from the first plate, a spacer element having an orifice formed therein and being positioned between the first and second plates to maintain the first and second plates in a spaced apart relationship, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof such that a fluid flow is generated and projected out from the orifice. The vibrational fluid mover assembly also includes an absorber system connected to the vibrational fluid mover and providing active damping to the vibrational fluid mover, with the absorber system having suspension tabs coupled to the vibrational fluid mover and spring components configured to mount the vibrational fluid mover in a suspended arrangement.
