Abstract

Provided is a mobile terminal including a terminal body, a printed circuit board provided in the terminal body, and a microphone provided on the printed circuit board a prescribed distance from the terminal body. The printed circuit board may be provided between an opening in the terminal body and the microphone, and a channel may be provided that extends from the opening in the terminal body to the microphone.

Claims

1. A mobile terminal comprising:

a terminal body;

a printed circuit board provided in the terminal body; and

a microphone provided on the printed circuit board a prescribed distance from the terminal body,

wherein the printed circuit board is provided between an opening in the terminal body and the microphone, and a channel is provided that extends from the opening in the terminal body to the microphone.

2. The mobile terminal of claim 1, wherein a first surface of the printed circuit board is provided closer to the opening in the terminal body than a second surface of the printed circuit board, the microphone being provided at the second surface.

3. The mobile terminal of claim 2, wherein the first surface is an upper surface of the printed circuit board and second surfaces is a lower surface of the printed circuit board, the first and second surfaces being opposite surfaces.

4. The mobile terminal of claim 3, wherein the printed circuit board extends perpendicular to the terminal body and a connection member is provided adjacent the terminal body and the printed circuit board, and

wherein the channel is provided in the connection member and extends from the opening in the terminal body to the first surface of the printed circuit board.

5. The mobile terminal of claim 4, wherein a hole is formed through the printed circuit board to correspond to the microphone and the channel.

6. The mobile terminal of claim 5, wherein a diameter of the channel is greater than a diameter of the opening in the terminal body or the hole in the printed circuit board.

7. The mobile terminal of claim 4, wherein the opening in the terminal body is formed on a side surface of the terminal body.

8. The mobile terminal of claim 7, wherein the channel extends perpendicular to the printed circuit board, and is angled at a prescribed angle to extend to the opening in the terminal case.

9. The mobile terminal of claim 4, wherein the connection member is made of elastic rubber or synthetic resin.

10. The mobile terminal of claim 2, wherein the first surface is a lateral surface of the printed circuit board and the second surface is an upper or lower surface of the printed circuit board, and wherein the first surface is positioned to cover at least a portion of the opening and the second surface extends perpendicular to the terminal body.

11. The mobile terminal of claim 10, wherein the channel is formed in the printed circuit board, a first distal end of the channel being provided on the later surface of the printed circuit board and a second distal end of the channel being provided on the upper or lower surface of the printed circuit board at the microphone.

12. The mobile terminal of claim 1, further including a heat sink device provided on a surface in the channel, the heat sink device being thermally coupled to an electrical device mounted on the printed circuit board to dissipate heat generated by the electrical device through the channel.

13. The mobile terminal of claim 12, wherein the heat sink device contacts the terminal body and at least a portion of the terminal body that contacts the heat sink device is made of a metal.

14. The mobile terminal of claim 1, further including a heat sink device that thermally couples the electrical device to the opening in the terminal body, the heat sink device provided such that a gap is provided between the heat sink device and a surface of the channel.

15. A mobile terminal comprising:

a terminal body;

a printed circuit board provided in the terminal body; and

an electric device provided on a surface of the printed circuit board,

wherein the electrical device is provided on the printed circuit board a prescribed distance from the terminal body, and a channel formed through the printed circuit board extends from an opening in the terminal body to the electrical device such that heat generated by the electrical device is dissipated through the channel and the opening.

16. The mobile terminal of claim 15, wherein a thermal conductor is provided on a surface of the channel.

17. The mobile terminal of claim 16, wherein the thermal conductor extends from the electrical device to the opening.

18. The mobile terminal of claim 16, wherein the thermal conductor device extends from the electrical device to a lateral surface of the printed circuit board that contacts the terminal body, and wherein at least a portion of the terminal body that contacts the thermal conductor device is made of a metal.

19. The mobile terminal of claim 15, further including a heat sink device that thermally couples the electrical device to the opening in the terminal body, the heat sink device provided such that a gap is provided between the heat sink device and a surface of the channel.

20. The mobile terminal of claim 15, wherein the channel extends from the opening in the terminal body to a microphone provided on a surface of the printed circuit board, and configured to guide sound through the opening to the microphone.
