Abstract

A cover for an electronic device includes a transparent portion and a non-transparent portion beside the transparent portion. The transparent portion defines a display area of the electronic device. The non-transparent portion defines a non-display area of the electronic device beside the display area. The non-transparent portion includes a transparent substrate integrated with the transparent portion. A plurality of through holes are defined on the transparent substrate.

First claim

What is claimed is:

1. A cover for an electronic device comprising:
a transparent portion defining a display area of the electronic device; and
a non-transparent portion defining a non-display area of the electronic device beside the display area, wherein the non-transparent portion comprises a transparent substrate integrated with the transparent portion, and the transparent substrate defines a plurality of through holes; the transparent substrate further comprises an adhesive layer adhered to an inner wall of each of at least one of the through holes; a color of the adhesive layer is the same as the non-transparent portion.

2. The cover as claimed in claim 1 , wherein the transparent substrate further comprises a shield layer formed on a surface of the transparent substrate, the shielding layer and the adhesive layer are formed using the same material in a same manufacturing process.

3. The cover as claimed in claim 1 , wherein the transparent substrate further comprises a shield layer formed on a surface of the transparent substrate, the shielding layer has the same color as the adhesive layer to decrease a visibility of the at least one through holes.

4. The cover as claimed in claim 1 , wherein the transparent substrate further comprises a shield layer formed on a surface of the transparent substrate, a color of the shielding layer is different from a color of the adhesive layer to improve a visibility of the at least one through holes.

5. The cover as claimed in claim 1 , wherein the plurality of through holes comprise a plurality of circular sound output holes to output sound output from the electronic device.

6. The cover as claimed in claim 5 , wherein a distance between two centers of each adjacent sound output holes is 0.2 millimeters to 2 millimeters.

7. The cover as claimed in claim 1 , wherein each of the each of the through holes is circular, the plurality of through holes are distributed at a same side of the display area, and diameters of the through holes descend along a direction away from the display area.

8. The cover as claimed in claim 1 , wherein the transparent substrate defines a groove at an inner surface, and a patterned adhesive layer is formed on the groove.

9. An electronic device comprising:
a cover comprising:
a transparent portion defining a display area of the electronic device; and
a non-transparent portion defining a non-transparent area of the electronic device beside the display area, the non-transparent portion comprising a transparent substrate integrated with the transparent portion, the transparent substrate defining a plurality of through holes; the transparent substrate further comprises an adhesive layer adhered to an inner wall of each of at least one of the through holes; a color of the adhesive layer is the same as the non-transparent portion.

10. The electronic device as claimed in claim 9 , further comprising a logo formed by the plurality of through holes.

11. The electronic device as claimed in claim 9 , wherein the transparent substrate further comprises a shield layer formed on a surface of the transparent substrate, the shielding layer and the adhesive layer are formed using the same material in a same manufacturing process.

12. The cover as claimed in claim 9 , wherein the transparent substrate defines a groove at an inner surface, and a patterned adhesive layer is formed on the groove.

13. The electronic device as claimed in claim 9 , wherein the electronic device further comprises at least one microphone, at least one of the through holes is located corresponding to the at least one microphone and configured to transmit external sound to the at least one microphone.

14. The electronic device as claimed in claim 9 , wherein through holes comprise at least one heat dissipation hole to dissipate heat produced by the electronic device.

15. The electronic device as claimed in claim 9 , wherein the electronic device further comprises at least on illumination component located near an inner side of the cover corresponding to the through holes to illuminate the through holes.

16. A method for manufacturing a cover for an electronic device, comprising:
providing a cover base having a transparent portion and a non-transparent portion beside the transparent portion, the non-transparent portion comprising a transparent substrate; and
forming a plurality of through holes on the transparent substrate;
forming an adhesive layer in an inner wall of each of at least one of the through holes; and
forming a shielding layer on a surface of the transparent substrate corresponding to the plurality of through holes, wherein the shielding layer has a same color as the adhesive layer.

17. The method as claimed in claim 16 , wherein the step of forming an adhesive layer in an inner wall of each of at least one of the through holes comprises:
filling adhesive material into each of the at least one of the through holes; and
removing a portion of the adhesive material from each of the at least one of the through holes.
