Abstract

A dust cover includes an anti-dust portion and an adhering portion integrally formed for framing the anti-dust portion. The anti-dust portion is a mesh sheet. The adhering portion is integrally formed on the anti-dust portion via a heat pressing process. The anti-dust portion is a coarser mesh, and the adhering portion is a mesh sheet with finer holes. The disclosure further provides a method for making the dust cover and an electronic device using the dust cover.

Claims

1. A dust cover, comprising:

an anti-dust portion being a mesh sheet; and

an adhering portion integrally formed framing the anti-dust portion;

wherein, the anti-dust portion is of a coarser mesh, and the adhering portion is a mesh sheet with a plurality of finer holes.

2. The dust cover of claim 1, wherein the adhering portion has greater surface area than that of the anti-dust portion.

3. The dust cover of claim 1, wherein the adhering portion is an encircled frame integrally formed adjacent to a peripheral edge of one surface of the anti-dust portion.

4. A method for making a dust cover, comprising the following steps:

providing a mesh object; and

heat pressing the mesh object to form an adhering portion adjacent to a peripheral edge of one surface of the mesh object and an anti-dust portion surrounded by the adhering portion;

wherein, the anti-dust portion is a coarser mesh, and the adhering portion is a mesh sheet with a plurality of finer holes.

5. The method of claim 4, wherein the adhering portion has greater surface area than that of the anti-dust portion.

6. The dust cover of claim 4, wherein the mesh object is made of nylon material, and the heat pressing temperature of the heat pressing process is controlled between 80 to 120 degrees Celsius.

7. The dust cover of claim 6, wherein the heat pressing temperature of the heat pressing process is about 96 degrees Celsius.

8. An electronic device, comprising:

a housing defining a speaker hole; and

a dust cover fixedly mounted to the housing for covering the speaker hole of the housing, the dust cover comprising;

an anti-dust portion being a mesh sheet; and

an adhering portion integrally formed framing the anti-dust portion;

wherein, the anti-dust portion is a coarser mesh, and the adhering portion is a mesh sheet with a plurality of finer holes.

9. The electronic device of claim 8, wherein the adhering portion comprises an adhering surface, the adhering surface of the adhering portion has greater surface area than that of the anti-dust portion.

10. The electronic device of claim 8, wherein the adhering portion is an encircled frame integrally formed adjacent to a peripheral edge of one surface of the anti-dust portion.
