## Abstract

The disclosure provides textured glass components as well as electronic device cover assemblies and enclosures which include the textured glass components. In some cases, a protruding portion of the glass component includes a textured region provided over a camera assembly of the electronic device. One or more openings may be provided in the textured region. The textured region may be configured to provide a translucent or hazy appearance to the electronic device while providing a desirable “feel” to the electronic device and level of cleanability.

## Claims

### Claim 1

A mobile phone comprising:
a camera assembly including an array of camera modules; and
an enclosure at least partially enclosing the camera assembly and including a rear cover assembly comprising:
a base portion defining a first textured glass surface having a first gloss value;
a protruding portion defining a second textured glass surface having a second gloss value different from the first gloss value; and
an array of openings formed in the protruding portion, each camera module of the array of camera modules extending at least partially through a respective opening of the array of openings.

### Claim 2 (depends on 1)

The mobile phone of claim 1, wherein the second gloss value is less than the first gloss value.

### Claim 3 (depends on 2)

The mobile phone of claim 2, wherein the second textured glass surface has a root mean square height greater than the root mean square height of the first textured glass surface.

### Claim 4 (depends on 2)

The mobile phone of claim 2, wherein:
the rear cover assembly further comprises:
a glass cover member that defines the base portion and the protruding portion; and
a coating along an interior surface of the glass cover member; and
the second gloss value is less than 50 as measured at 60 degrees and in the absence of the coating.

### Claim 5 (depends on 1)

The mobile phone of claim 1, wherein a thickness of the protruding portion is greater than a thickness of the base portion.

### Claim 6 (depends on 1)

The mobile phone of claim 1, wherein at least one camera module of the array of camera modules is proud of the second textured glass surface.

### Claim 7 (depends on 1)

The mobile phone of claim 1, wherein:
the mobile phone further comprises a display positioned within the enclosure; and
the enclosure further comprises a front cover assembly positioned over the display.

### Claim 8

A mobile phone comprising:
an enclosure including a rear cover assembly comprising:
a first glass portion defining a first exterior surface having a first root mean square height;
a second glass portion defining a second exterior surface that protrudes with respect to the first exterior surface, the second exterior surface having a second root mean square height, different than the first root mean square height; and
an array of openings formed in the second glass portion; and
an array of camera modules positioned at partially within the enclosure, each camera module of the array of camera modules extending at least partially through a respective opening of the array of openings.

### Claim 9 (depends on 8)

The mobile phone of claim 8, wherein the second root mean square height is greater than the first root mean square height.

### Claim 10 (depends on 9)

The mobile phone of claim 9, wherein the second glass portion has a higher transmissive haze than the first glass portion.

### Claim 11 (depends on 9)

The mobile phone of claim 9, wherein the second root mean square height ranges from 0.2 microns to 2 microns.

### Claim 12 (depends on 8)

The mobile phone of claim 8, wherein the second glass portion has a second thickness that is at least 25% greater than a first thickness of the first glass portion.

### Claim 13 (depends on 8)

The mobile phone of claim 8, wherein the first glass portion at least partially surrounds the second glass portion.

### Claim 14 (depends on 8)

The mobile phone of claim 8, wherein each of the first glass portion and the second glass portion is chemically strengthened.

### Claim 15

A mobile phone comprising:
an enclosure including a cover assembly comprising:

a second portion defining:
a second textured glass surface that is offset with respect to the first textured glass surface, the second textured glass surface having a second root mean square slope different than the first root mean square slope; and
an array of openings; and
an array of camera modules positioned within the enclosure, each camera module of the array of camera modules extending at least partially through a respective opening of the array of openings.

### Claim 16 (depends on 15)

The mobile phone of claim 15, wherein the second root mean square slope is greater than the first root mean square slope.

### Claim 17 (depends on 16)
