Gasket and associated apparatus and methods

1. A gasket for acoustically sealing an audio component inside an electronic apparatus, the gasket comprising a plurality of channels extending through a majority of a thickness between opposite sides of the gasket, the gasket being configured to provide a lower acoustic resistance through the channels than transverse to the channels.

2. The gasket of claim 1 wherein each channel is dimensioned to inhibit the passage of dust through the channel.

3. The gasket of claim 1 wherein the gasket is for sealing an audio component which is mounted to a printed wiring board.

4. The gasket of claim 1 wherein gasket channel openings are dimensioned to have apertures which are smaller than a sonic aperture in the audio component.

5. The gasket of claim 1 wherein gasket channel openings are dimensioned to have apertures which are smaller than a sonic aperture in the electronic apparatus.

6. The gasket of claim 1 comprising a honeycomb arrangement of adjacent elongate channels.

7. The gasket of claim 1 comprising substantially parallel elongate channels.

8. The gasket of claim 1 wherein each channel extends rectilinearly through the gasket.

9. The gasket of claim 1 formed of a compressible material.

10. The gasket of claim 1 formed of an elastomer material.

11. An electronic apparatus comprising

a casing having an aperture region with an aperture;

an audio component arranged to be in sonic communication with the aperture; and

a gasket comprising a plurality of channels extending through a majority of a thickness between opposite sides of the gasket, the gasket being configured to provide a lower acoustic resistance through the channels than transverse to the channels, the gasket arranged to be interposed between the audio component and the aperture region of the casing and arranged such that its channels extend in a desired direction of said sonic communication.

12. The apparatus of claim 11 , wherein gasket channel openings are dimensioned to have apertures which are smaller than a sonic aperture in the audio component.

13. The apparatus of claim 11 wherein gasket channel openings are dimensioned to have apertures which are smaller than a sonic aperture in the electronic apparatus.

14. The electronic apparatus of claim 11 configured such that the gasket is under compression between the audio component and the aperture region.

15. The electronic apparatus of claim 11 wherein the apparatus is an electronic device.

16. The electronic apparatus of claim 11 wherein the apparatus is an electronic device module.

17. A module for an electronic apparatus, the module comprising

an audio component arrangeable to be in sonic communication with an aperture of a casing of the electronic apparatus; and

a gasket comprising a plurality of channels extending through a majority of a thickness between opposite exterior sides of the gasket, the gasket being configured to provide a lower acoustic resistance through the channels than transverse to the channels, the gasket arrangeable to be interposed between the audio component and an aperture region of the casing having the aperture and arrangeable such that its channels extend in a desired direction of said sonic communication.

18. A gasket means for acoustically sealing an audio component inside an electronic apparatus, the gasket means comprising a plurality of channels extending through a majority of a thickness between opposite exterior sides of the gasket and being configured to provide a lower acoustic resistance through the channels than transverse to the channels.

19. A method of assembling an electronic apparatus, the method comprising

interposing a gasket between an audio component and an aperture region of the casing having an aperture, the gasket comprising a plurality of channels extending through a majority of a thickness between opposite exterior sides of the gasket, the gasket being configured to provide a lower acoustic resistance through the channels than transverse to the channels; and

arranging the gasket such that its channels extend in a desired direction of sonic communication between the audio component and the aperture.

20. The method of claim 19 comprising compressing the gasket between the audio component and the aperture region.

21. The gasket of claim 1 wherein the channels extend entirely through the gasket between opposite sides of the gasket with a substantially uniform cross section between the opposite sides.

22. The apparatus of claim 11 , wherein the apparatus does not comprise a separate dust cloth between the gasket and the casing, and wherein the channels are sized sufficiently small to inhibit passage of dust through the channels.
