Abstract

A mobile terminal includes: a main body with a top surface, a bottom surface, and a back surface; and a case surrounding the main body, the case including: a top side portion covering the top surface of the main body; a backside portion including a first backside portion positioned in the upper part and covering the back of the main body and a second backside portion positioned below the first backside portion and covering the back of the main body; and a bottom side portion covering the bottom surface of the main body, wherein the top side portion, first backside portion, second backside portion, and bottom side portion may be made of a metal material, and separated from one another by a non-metal member, and the non-metal member may have a light-emitting portion that gives off light.

First claim

What is claimed is:

1. A mobile terminal comprising:
a main body having a top surface, a bottom surface, and a back surface; and
a case surrounding the main body, the case including:
a top portion covering the top surface of the main body;
a first back portion positioned at an upper part of the back surface and covering at least a first portion of the back surface;
a second back portion positioned below the first back portion and covering at least a second portion of the back surface; and
a bottom side portion covering the bottom surface of the main body,

wherein the top portion, first back portion, second back portion, and bottom side portion are made of a metal material,
wherein the top portion, first back portion, second back portion, and bottom side portion are separated from one another by a non-metal member,
wherein the non-metal member has a light-emitting portion that gives off light,
wherein the light-emitting portion comprises:
a translucent portion; and
a light source provided below the translucent portion,

wherein opposite ends of the translucent portion are curved toward a front of the mobile terminal from a back of the mobile terminal to provide a curved part, the translucent portion including a pair of hook portions formed on an inside of the curved part, the pair of hook portions extending towards each other, and
wherein a front display is seated on the pair of hooks.

2. The mobile terminal of claim 1 , wherein the non-metal member comprises:
a first non-metal member that separates the top portion and the first back portion;
a second non-metal member that separates the first back portion and the second back portion; and
a third non-metal member that separates the second back portion and the bottom side portion.

3. The mobile terminal of claim 2 , wherein the light-emitting portion further comprises a light guide portion provided below the translucent portion and made of a transparent material that transmits light from the light source.

4. The mobile terminal of claim 3 , wherein grooves are formed at regular intervals on a bottom surface of the light guide portion, and a variety of patterns are formed by the spacing between the grooves.

5. The mobile terminal of claim 2 , wherein the light-emitting portion is a sub-display portion that displays information, the sub-display portion including:
a rear window;
a rear display; and
a support member that fixes the rear window and the rear display to the main body.

6. The mobile terminal of claim 5 , wherein the sub-display portion is curved to correspond to a shape of the mobile terminal.

7. The mobile terminal of claim 5 , wherein light shielding tape is provided between the rear display and the main body.

8. The mobile terminal of claim 1 , wherein the translucent portion includes bonding portions arranged between the pair of hook portions, and
wherein the bonding portions protrude toward the main body such that the second non-metal member is fixed to the main body.

9. The mobile terminal of claim 2 , wherein the top portion, first back portion, and bottom side portion are connected to a printed circuit board such that the top portion provides a first antenna radiator, the first back portion provides a second antenna radiator, and the bottom side portion provides a third antenna radiator, and
wherein the second back portion is electrically connected to the printed circuit board to provide a ground portion.

10. The mobile terminal of claim 9 , further comprising first and second flexible circuit boards connected to the printed circuit board and spaced apart from each other, the first and second flexible circuit boards being provided near the top surface of the main body,
wherein the first and second flexible circuit boards include respective first and second feed connecting portions electrically connected to the top portion to feed the top portion.

11. The mobile terminal of claim 9 , further comprising third feed connecting portions on the printed circuit board at the upper part of the back surface, the third feed connecting portions being electrically connected to the first back portion to feed the first back portion.

12. The mobile terminal of claim 9 , further comprising:
a fourth feed connecting portion on the printed circuit board on one side of the bottom surface of the main body;
a fourth carrier connected to the fourth feed connecting portion and having a metal pattern; and
a fourth contact terminal formed at the fourth carrier and contacting the bottom side portion.

13. The mobile terminal of claim 12 , further comprising:
a fifth feed connecting portion on the printed circuit board provided on another side of the bottom surface of the main body;
a fifth carrier connected to the fifth feed connecting portion and having a metal pattern; and
a fifth contact terminal formed at the fifth carrier and contacting the bottom side portion.

14. The mobile terminal of claim 13 , wherein the fourth carrier and the fifth carrier each includes an audio input portion.

15. The mobile terminal of claim 9 , wherein the first non-metal member defines a slit between the first antenna radiator and the second antenna radiator,
wherein the second non-metal member defines a slit between the second antenna radiator and the ground, and
wherein the third non-metal member defines a slit between the ground and the third antenna radiator.

16. The mobile terminal of claim 1 , wherein a thickness of the mobile terminal at the first back portion is larger than a thickness of the mobile terminal at the second back portion.

17. The mobile terminal of claim 1 , wherein the light-emitting portion is configured to provide an indicator representative of at least one of a message reception, a call signal reception, a missed call, an alarm, a schedule reminder, data received from an application, or text/multimedia message transmission and reception.

18. The mobile terminal of claim 1 , wherein the main body further includes a front surface, the front display being located at the front surface, and the back surface being opposite the front surface.
