Castellated cosmetic mesh stiffener for acoustic flow noise reduction
An electronic device can include a housing defining a first aperture and at least partially defining an internal volume. An air permeable component can be disposed at the first aperture and the device can include a support component defining a second aperture within the first aperture and engaging the air permeable component. The support component can include a sidewall disposed in the first aperture and defining at least one notch.
1. An electronic device, comprising:
a housing defining a first aperture and at least partially defining an internal volume;
an air permeable component disposed at the first aperture; and
a support component engaging the air permeable component and defining a second aperture in communication with the first aperture;
the support component comprising a sidewall disposed in the first aperture and defining at least one notch.
2. The electronic device of claim 1 , wherein the sidewall defines an open flux area that is at least 10% larger than an area of the first aperture and in communication with the second aperture.
3. The electronic device of claim 1 , further comprising a speaker disposed in the internal volume.
4. The electronic device of claim 1 , wherein the sidewall defines at least six notches.
5. The electronic device of claim 1 , wherein the sidewall surrounds a periphery of the second aperture.
6. The electronic device of claim 1 , wherein the air permeable component comprises an acoustic mesh.
7. The electronic device of claim 1 , wherein the support component comprises steel.
8. The electronic device of claim 1 , wherein at least a portion of the air permeable component is disposed between the support component and a portion of the housing defining the first aperture.
9. The electronic device of claim 1 , wherein the support component comprises a base extending perpendicularly from the sidewall, and the base is adhered to an interior surface defined by the housing.
10. An acoustic cover assembly, comprising:
an air permeable component; and
a support component engaged with the air permeable component, the support component comprising;
a base defining an aperture;
a sidewall extending from the base adjacent to the aperture, the sidewall comprising at least two protruding members;
the sidewall defining an open flux area at least 10% larger than an area of the aperture and in communication with the aperture.
11. The acoustic cover assembly of claim 10 , wherein the sidewall comprises:
a first portion extending from the base adjacent to a first peripheral portion of the aperture in a direction;
a first set of protruding members extending from the first portion in the direction;
a second portion extending from the base adjacent to a second peripheral portion of the aperture, the second peripheral portion opposite the first peripheral portion; and
a second set of protruding members extending from the second portion in the direction.
12. The acoustic cover assembly of claim 11 , wherein the first set of protruding members comprises two protruding members, and the second set of protruding members comprises two protruding members.
13. The acoustic cover assembly of claim 10 , wherein the open flux area is at least 15% larger than the area of the aperture.
14. The acoustic cover assembly of claim 10 , wherein the protruding members have a rectangular shape.
15. The acoustic cover assembly of claim 10 , wherein the protruding members have a triangular or rounded shape.
16. The acoustic cover assembly of claim 10 , wherein the protruding members define a top surface of the support component that is nonparallel relative to the base.
17. A method of forming a support component for an air permeable component, comprising:
drawing a body into a shape defining a recess;
forming multiple first apertures in the body defining the recess;
further drawing the body to increase a depth of the recess; and
removing a portion of the body defining the recess to define a second aperture and at least one protrusion adjacent to the second aperture.
18. The method of claim 17 , wherein the at least one protrusion comprises a castellated sidewall defining an open flux area at least 10% larger than the second aperture when supporting the air permeable component.
19. The method of claim 17 , wherein the support component comprises a base and a sidewall extending from the base, at least one protrusion extending from the sidewall and having a top surface that is nonparallel relative to the base.
20. The method of claim 17 , wherein forming multiple first apertures comprises forming three first apertures in a portion of the body defining the recess.
