Abstract
A synthetic jet ejector (201) is provided which includes a chassis (203); first (205) and second (207) opposing synthetic jet actuators mounted in the chassis; and a controller (209) which controls the first and second synthetic jet actuators and which is in electrical contact with the first and second synthetic jet actuators by way of flexible circuitry (211, 213).
Claims41
A synthetic jet ejector, comprising:
- a chassis;
- first and second opposing synthetic jet actuators mounted in said chassis;
- and
- a controller which controls said first and second synthetic jet actuators and which is in electrical contact with said first and second synthetic jet actuators by way of flexible circuitry, the controller including a PCB mounted on an exterior surface of said chassis.

25-31. (canceled)
A synthetic jet ejector, comprising:
- a chassis;
- at least one synthetic jet actuator supported on said chassis;
- and
- a back iron having an essentially annular wall with a plurality of holes therein;
- wherein said chassis extends through said plurality of holes.
36-39. (canceled)
45-47. (canceled)
A synthetic jet ejector, comprising:
- a bobbin;
- and
- a diaphragm;
- wherein said bobbin has a circumferential groove on one end thereof, and wherein said diaphragm has a complimentary-shaped circumferential protrusion which releasably engages said circumferential groove.
49-50. (canceled)
A synthetic jet ejector, comprising:
- a back iron;
- a chassis having a first chassis component disposed outside of the wall of said back iron, and a second chassis component disposed inside the wall of said back iron;
- and
- a magnet supported on said second chassis component;
- wherein said magnet is cylindrical in shape, and wherein said second chassis component contains an annular indentation which is complimentary in shape to a portion of the exterior shape of said magnet.
A method for making a synthetic jet ejector, comprising:
- arranging a back iron and magnet within a mold, wherein said back iron has an annular wall with a plurality of apertures therein, and wherein said magnet is disposed within said annular wall;
- and
- molding a chassis around said back iron and magnet such that the chassis supports the back iron and the magnet and such that the molding material extends through the apertures in the annular wall.
61-62. (canceled)
(canceled)
A method for making a synthetic jet ejector, comprising:
- providing a bobbin having an annular lip with a circumferential groove defined therein;
- providing an elastomeric diaphragm having a central opening therein, wherein said central opening is equipped with an annular ridge and has a diameter that is essentially the same as the diameter of the annular lip;
- and
- positioning the diaphragm with respect to the bobbin such that the annular ridge engages the annular groove.
A method for making a synthetic jet ejector, comprising:
- providing a bobbin having first and second terminals and having a coil of wire disposed thereon which has first and second ends which are attached to said first and second terminals, respectively;
- attaching an annular lip with a circumferential groove defined therein;
- providing an elastomeric diaphragm having a central opening therein, wherein said central opening is equipped with an annular ridge and has a diameter that is essentially the same as the diameter of the annular lip;
- and
- positioning the diaphragm with respect to the bobbin such that the annular ridge engages the annular groove.
