Abstract

An electromagnetic interference (EMI) gasket is provided that includes a resiliently-flexible and conductive outer shell, a cushioning element disposed in the outer shell, and at least one magnetic component disposed in the outer shell configured to magnetically couple to a conductive surface of an electronic device chassis.

First claim

What is claimed is:

1. An electromagnetic interference gasket comprising:
a resiliently-flexible and conductive outer shell;
at least one cushioning element disposed in the outer shell; and
a plurality of magnetic components disposed in the outer shell configured to magnetically couple to a conductive surface of an electronic device chassis, wherein the plurality of magnetic components are distributed throughout the at least one cushioning element.

2. The electromagnetic interference gasket of claim 1 , further comprising at least one magnetic component that comprises a resiliently-flexible magnetic element disposed between the at least one cushioning element and the outer shell.

3. The electromagnetic interference gasket of claim 2 , wherein the at least one cushioning element includes a cutout for the at least one magnetic component.

4. The electromagnetic interference gasket of claim 1 , wherein at least one magnetic component of the plurality of magnetic components comprises an elongated magnet.

5. The electromagnetic interference gasket of claim 1 , wherein the outer shell comprises a conductive fabric.

6. The electromagnetic interference gasket of claim 1 , wherein the at least one cushioning element comprises a foam.

7. A method for manufacturing an electromagnetic interference gasket, comprising:
providing a resiliently-flexible and conductive outer shell;
positioning at least one cushioning element in the outer shell; and
positioning a plurality of magnetic components in the outer shell, wherein the least one magnetic component is configured to magnetically couple to a conductive surface of an electronic device chassis, wherein the plurality of magnetic components are distributed throughout the at least one cushioning element.

8. The method of claim 7 , further comprising:
adhering at least one magnetic component to the at least one cushioning element.

9. The method of claim 8 , further comprising:
simultaneously inserting the at least one magnetic component of the plurality of magnetic components and the at least one cushioning element into the outer shell.

10. The method of claim 7 , further comprising:
preparing a cutout in the at least one cushioning element.

11. The method of claim 10 , further comprising:
positioning at least one magnetic component of the plurality of magnetic components in the cutout.

12. The method of claim 7 , wherein at least one magnetic component of the plurality of magnetic components comprises an elongated magnet.

13. The method of claim 12 , wherein:
positioning the at least one magnetic component in the outer shell comprises inserting the elongated magnet into the outer shell.

14. The method of claim 7 , wherein the outer shell is a conductive fabric.

15. The method of claim 7 , wherein the at least one cushioning element comprises a foam.

16. An electromagnetic interference gasket comprising:
a resiliently-flexible and conductive fabric;
a cushioning element substantially enclosed by the conductive fabric; and
a plurality of elongated magnet components disposed in the conductive fabric, wherein the plurality of elongated magnet components are distributed throughout the cushioning element.

17. The electromagnetic interference gasket of claim 16 , further comprising at least one elongated magnet component disposed between the cushioning element and the conductive fabric.

18. The electromagnetic interference gasket of claim 16 , wherein the cushioning element includes a cutout for at least one elongated magnet component of the plurality of magnet components.

19. The electromagnetic interference gasket of claim 16 , wherein at least one elongated magnet component of the plurality of elongated magnet components is resiliently-flexible.

20. The electromagnetic interference gasket of claim 16 , wherein the cushioning element comprises a foam.
