摘要：
A synthetic jet assembly (10) includes a synthetic jet (12) having a cavity (20) and an opening (30) formed therein. The synthetic jet assembly also includes an actuator element (34,36) coupled to a flexible surface (24,26) of the body to selectively cause displacement of the second surface, and a control unit (42) electrically coupled to the actuator element. The control unit is configured to transmit a multi-frequency drive signal (56) to the actuator element, the multi-frequency drive signal comprising a cooling frequency component (58) and an acoustic frequency component (60) 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.
