Patent ID: 8827179

Claim:
A synthetic jet actuator comprising: a first plate; a second plate spaced apart from the first plate and arranged parallelly thereto; a housing positioned about the first and second plates and defining a chamber, the housing having a pair of orifices formed therein in opposing sides of the housing such that the chamber is in fluid communication with an external environment; an adhesive configured to mount the first and second plates within the housing in a suspended arrangement, the adhesive being applied to at least a portion of an outward facing surface of each of the first and second plates; and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof, so that fluid vortices are generated and projected to the external environment out from the pair of orifices of the housing in opposite directions; wherein the adhesive comprises a flexible adhesive configured to allow for interference-free deflection of the first and second plates, such that the first and second plates are allowed to vibrate at their natural frequency so as to reduce noise generated by the synthetic jet actuator.
