Abstract
A system and method for lowering resonant frequency in a synthetic jet device for less noise, as well as lowering vibration, is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first or second plates to selectively cause deflection thereof, wherein the first and second plates are formed at least in part of a non-metallic material.
Claims22
A synthetic jet device comprising:
- a first plate;
- a second plate spaced apart from the first plate;
- a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein;
- and
- an actuator element coupled to at least one of the first or second plates to selectively cause deflection thereof;
- wherein the first and second plates are formed at least in part of a non-metallic material.
A method of fabricating a synthetic jet device comprising:
- constructing a first plate and a second plate at least in part of a non-metallic material;
- attaching an actuator element to at least one of the first and second plates to selectively cause deflection thereof;
- positioning the first plate relative to the second plate by way of a spacing component, the spacing component securing the first plate to the second plate in a spaced apart arrangement to form a chamber and including an orifice therein;
- and
- attaching electrical connections to the actuator element and the respective one of the first and second plates to which the actuator element is attached so as to enable a selective applying of voltage to the actuator element.
A synthetic jet device comprising:
- a first plate;
- a second plate spaced apart from the first plate to form a chamber;
- and
- an actuator element coupled to at least one of the first or second plates to selectively cause deflection thereof so as to change a volume of the chamber;
- wherein each of the first and second plates comprises:
- a first material comprising an electrically insulating, non-metallic material;
- and
- a second material comprising an electrically conductive material, the second material being formed as one of a filler material, a metalizing layer, and internally or externally formed leads provided on or in the first material.
