Abstract

A portable electronic device is provided, which includes a circuit board, and a radiator arranged along an edge of the circuit board on one side of the circuit board.

Claims

1. A portable electronic device comprising:

a circuit board;

a recessed portion formed on a first side of the circuit board;

an opening formed in the recessed portion;

a clip member supported on a surface of the recessed portion; and

a radiator accommodated in the recessed portion and disposed along an edge of the circuit board on the first side of the circuit board,

wherein an elastic piece of the clip member is accommodated in the opening to be in contact with the radiator.

2. The portable electronic device of claim 1, further comprising a ferrite member interposed between the radiator and the first side of the circuit board.

3. The portable electronic device of claim 2, wherein the ferrite member is disposed between the radiator and the surface of the recessed portion.

4. The portable electronic device of claim 1, wherein the clip member includes a fixed piece which is at least partially fixed around the opening, and the elastic piece extends from the fixed piece.

5. The portable electronic device of claim 1, wherein the recessed portion is exposed at a periphery of the circuit board.

6. The portable electronic device of claim 1, wherein the radiator utilizes a conductive pattern formed along the edge of the circuit board on the first side of the circuit board.

7. The portable electronic device of claim 1, further comprising a board housing that accommodates the circuit board,

wherein the radiator is disposed to face a front side of the board housing.

8. The portable electronic device of claim 7, further comprising two wearing members that extend from the board housing in opposite directions.

9. The portable electronic device of claim 7, further comprising a display device positioned on the front side of the board housing.

10. A portable electronic device comprising:

a circuit board;

a radiator disposed along an edge of the circuit board on a first side of the circuit board; and

a ferrite member disposed on a second side of the circuit board,

wherein the circuit board includes a fill-cut region formed between a conductive pattern and the ferrite member.

11. The portable electronic device of claim 10, further comprising a recessed portion formed on the second side of the circuit board,

wherein the ferrite member is accommodated in the recessed portion.

12. The portable electronic device of claim 10, wherein a shape of the ferrite member corresponds to a region where the conductive pattern is formed.

13. The portable electronic device of claim 10, wherein the radiator utilizes the conductive pattern formed along the edge of the circuit board on the first side of the circuit board.
