Abstract
A synthetic jet assembly includes a synthetic jet having a cavity and an opening formed therein. The synthetic jet assembly also includes an actuator element coupled to a second surface of the body to selectively cause displacement of the second surface, and a control unit electrically coupled to the actuator element. The control unit is configured to transmit a multi-frequency drive signal to the actuator element, the multi-frequency drive signal comprising a cooling frequency component and an acoustic frequency component superimposed on the cooling frequency component. The cooling frequency component causes a cooling jet to eject from the opening of the body. The acoustic frequency component produces a desired audible output.
