Abstract

The present disclosure provides an electronic product metal shell and a method of manufacturing the same. The electronic product metal shell includes: a metal layer; a first hard anodic oxidation layer formed on an upper surface of the metal layer; a second hard anodic oxidation layer formed on a lower surface of the metal layer; an antenna groove penetrating through the metal layer and the first hard anodic oxidation layer; and a non-conductive material filled in the antenna groove.

First claim

What is claimed is:

1. An electronic product metal shell, comprising:
a metal layer;
a first hard anodic oxidation layer formed on an upper surface of the metal layer;
a second hard anodic oxidation layer formed on a lower surface of the metal layer;
an antenna groove penetrating through the metal layer and the first hard anodic oxidation layer to reach a surface of the second hard anodic oxidation layer; and
a non-conductive material filled in the antenna groove.

2. The electronic product metal shell of claim 1 , wherein a width of an upper opening of the antenna groove is larger than a width of a lower opening of the antenna groove.

3. The electronic product metal shell of claim 1 , wherein the metal layer includes an aluminum alloy layer.

4. An electronic product metal shell, comprising:
a metal layer having an antenna groove penetrating through the metal layer and a first hard anodic oxidation layer formed on an upper surface of the metal layer, wherein the antenna groove is filled with a non-conductive material; and
a second hard anodic oxidation layer formed on a lower surface of the metal layer, wherein the antenna groove reaches a surface of the second hard anodic oxidation layer.
