Abstract

A handheld computing device that includes an enclosure having structural walls formed from a glass material that can be radio-transparent. The enclosure can be formed from a hollow glass tube or two glass members bonded together. A laser frit bonding process may be used to hermetically seal the two glass members together to create a water resistant electronic device.

Claims

1. A portable electronic device, comprising:

an enclosure defining an internal volume and comprising;

a unitary housing component formed from a glass material and comprising;

a first glass member defining a glass front surface;

a second glass member defining a glass back surface; and

a glass band defining;

a first segment defining at least a portion of a glass first side surface of the enclosure;

a second segment parallel to the first segment and defining at least a portion of a glass second side surface of the enclosure;

a third segment defining at least a portion of a glass third side surface of the enclosure; and

a fourth segment parallel to the third segment and defining at least a portion of a glass fourth side surface of the enclosure; and

a touch-screen display assembly within the internal volume of the enclosure and configured to display graphical outputs visible through at least the glass front surface.

2. The portable electronic device of claim 1, wherein:

the unitary housing component defines a rail structure within the internal volume; and

the touch-screen display assembly is coupled to the rail structure.

3. The portable electronic device of claim 2, wherein the rail structure comprises two parallel rails.

4. The portable electronic device of claim 1, wherein:

the first glass member defines a first additional portion of each of the glass first, second, third, and fourth side surfaces; and

the second glass member defines a second additional portion of each of the glass first, second, third, and fourth side surfaces.

5. The portable electronic device of claim 4, wherein the first glass member is fused to the glass band.

6. The portable electronic device of claim 5, wherein the first glass member is fused to the glass band via a bonding layer formed at least in part of glass.

7. The portable electronic device of claim 1, wherein at least one of the first glass member, the second glass member, or the glass band defines a textured region having a surface texture that is different than an area of the enclosure surrounding the textured region.

8. A portable electronic device, comprising:

a glass enclosure defining an internal volume and comprising;

a front glass member defining a front surface of the glass enclosure;

a back glass member defining a back surface of the glass enclosure; and

a glass band positioned between the front glass member and the back glass member and defining;

at least a portion of a first side surface of the glass enclosure, the first side surface extending in a first direction;

at least a portion of a second side surface of the glass enclosure, the second side surface extending in a second direction parallel to the first direction;

at least a portion of a third side surface of the glass enclosure, the third side surface extending in a third direction; and

at least a portion of a fourth side surface of the glass enclosure, the fourth side surface extending in a fourth direction parallel to the third direction; and

a touch-screen assembly positioned within the internal volume and configured to detect a touch input applied to the front surface of the glass enclosure.

9. The portable electronic device of claim 8, wherein:

the portable electronic device further comprises a speaker positioned within the internal volume;

the glass enclosure defines an opening that is aligned with the speaker; and

a waterproof membrane is positioned over the speaker and covers the opening.

10. The portable electronic device of claim 8, wherein the glass enclosure further comprises:

a first bonding layer formed at least in part of glass and securing the front glass member to the glass band; and

a second bonding layer formed at least in part of glass and securing the back glass member to the glass band.

11. The portable electronic device of claim 8, wherein the glass enclosure further comprises adhesive securing the front glass member and the back glass member to the glass band.

12. The portable electronic device of claim 8, wherein:

the front surface defines a first plane;

the back surface defines a second plane; and

the first side surface defines a curved side profile extending from the first plane to the second plane.

13. The portable electronic device of claim 8, further comprising an opaque masking material on an interior surface of the back glass member.

14. A portable electronic device, comprising:

an enclosure comprising;

a first glass member defining a glass front surface;

a second glass member defining a glass back surface; and

a rectangular glass band defining at least a portion of each of four glass side surfaces around a periphery of the enclosure; and

a touch-screen display assembly within the enclosure and configured to display graphical outputs visible through the glass front surface.

15. The portable electronic device of claim 14, wherein the enclosure further comprises:

a first bonding layer formed at least in part of glass and securing the first glass member to the rectangular glass band; and

a second bonding layer formed at least in part of glass and securing the second glass member to the rectangular glass band.

16. The portable electronic device of claim 15, wherein:

the first bonding layer defines a first hermetic seal between the first glass member and the rectangular glass band; and

the second bonding layer defines a second hermetic seal between the second glass member and the rectangular glass band.

17. The portable electronic device of claim 14, wherein:

the portable electronic device further comprises a structural frame within the enclosure; and

the touch-screen display assembly is coupled to the structural frame.

18. The portable electronic device of claim 17, wherein

the structural frame comprises metal.

19. The portable electronic device of claim 14, wherein the rectangular glass band defines two pairs of parallel segments.

20. The portable electronic device of claim 14, wherein the rectangular glass band defines a textured region having a greater surface roughness than an adjacent region of the rectangular glass band.
