Abstract

The present invention relates to a wrist watch type mobile terminal, and may include a conductive metal housing connected with a band or strap to be worn on a human body, and formed to be operable as an antenna at a specific bandwidth, a wireless communication module configured to process a signal transmitted and/or received by the housing, and a feeding portion configured to electrically connect the metal housing with the wireless communication module. The metal housing thereof may function as an antenna transmitting and/or receiving a specific bandwidth, and thus has an advantage of facilitating the implementation of the wireless performance and improving the appearance thereof, compared to a case in which an antenna is disposed within the housing having a small and limited size.

Claims

1. A wrist watch type mobile terminal comprising:

a conductive metal housing formed to be operable as an antenna;

a wireless communication module configured to process at least one of a signal to be transmitted by the housing and a signal received by the housing;

a feeding portion configured to electrically connect the housing with the wireless communication module; and

a band or a strap connected to the housing, whereby the wrist watch type mobile terminal is capable of being worn.

2. The wrist watch type mobile terminal of claim 1, further comprising a display,

wherein an opening for mounting the display is formed on an upper surface of the housing.

3. The wrist watch type mobile terminal of claim 2, wherein the feeding portion is disposed at an inner side of an edge portion of the opening.

4. The wrist watch type mobile terminal of claim 3, further comprising a circuit board,

wherein an end portion of the feeding portion is fixed to the circuit board, and another end portion of the feeding portion is resiliently biased to contact the housing.

5. The wrist watch type mobile terminal of claim 1, further comprising a conductive metal cover mounted at a lower surface of the housing.

6. The wrist watch type mobile terminal of claim 5, wherein the cover directly contacts the housing.

7. The wrist watch type mobile terminal of claim 5, wherein the cover is spaced apart from the housing so as to not directly contact the housing.

8. The wrist watch type mobile terminal of claim 7, wherein an insulating spacer is provided between the cover and the housing.

9. The wrist watch type mobile terminal of claim 1, further comprising a plurality of push buttons,

wherein a lateral surface of the housing includes a plurality of through holes formed therein, and each of the push buttons is provided in a corresponding through hole to be pressably operated therethrough.

10. The wrist watch type mobile terminal of claim 9, wherein at least one of the plurality of push buttons is set to reset the mobile terminal when pressed for more than a predetermined period of time.

11. The wrist watch type mobile terminal of claim 2, wherein the wireless communication module is configured to operate with an external terminal at a BLUETOOTH bandwidth.

12. The wrist watch type mobile terminal of claim 2, wherein the wireless communication module is configured to communicate with an external terminal within a bandwidth of about 2400 MHz to 2483.5 MHz.

13. The wrist watch type mobile terminal of claim 2, wherein the display is configured to output at least any one of call information, message information, and multimedia information by a signal received from an external terminal.

14. The wrist watch type mobile terminal of claim 2, wherein the conductive metal housing is formed entirely of metal.

15. A wrist watch type mobile terminal comprising:

a conductive metal housing;

a circuit board assembly located in the housing, the circuit board assembly including;

a display;

a circuit board;

a frame configured to support the display and the circuit board; and

a feeding portion attached to the circuit board to make contact with the housing; and

a band or a strap connected to the housing, whereby the wrist watch type mobile terminal is capable of being worn.

16. The wrist watch type mobile terminal of claim 15, wherein the display, the circuit board, and the frame are integrated to form an integrated circuit board assembly.

17. The wrist watch type mobile terminal of claim 15, further comprising a battery mounted on the frame.

18. The wrist watch type mobile terminal of claim 15, wherein an insertion protrusion is formed on the frame to maintain a location of the circuit board assembly within the housing, and an engagement groove is formed on the housing to receive the insertion protrusion.

19. The wrist watch type mobile terminal of claim 15, wherein a penetration groove is formed at a side of the frame to allow the feeding portion to extend therethrough.

20. The wrist watch type mobile terminal of claim 15, wherein the feeding portion is formed with a C-shaped elastic spring.

21. A system for transferring and receiving information, the system comprising:

an external terminal having a first wireless communication module configured to transmit and/or receive information; and

a wrist watch type mobile terminal including;

a conductive metal housing formed to be operable as an antenna;

a second wireless communication module configured to process at least one of a signal to be transmitted by the housing and a signal received by the housing;

a feeding portion configured to electrically connect the housing with the wireless communication module; and

a band or a strap connected to the housing, whereby the wrist watch type mobile terminal is capable of being worn.

22. The system of claim 21, further comprising a display,

wherein an opening for mounting the display is formed on an upper surface of the housing.

23. The system of claim 22, wherein the feeding portion is disposed at an inner side of an edge portion of the opening.

24. The system of claim 23, further comprising a circuit board,

wherein an end portion of the feeding portion is fixed to the circuit board, and another end portion of the feeding portion is resiliently biased to contact the housing.

25. The system of claim 21, further comprising a circuit board assembly located in the housing, the circuit board assembly including:

a display;

a circuit board; and

a frame configured to support the display and the circuit board, wherein the feeding portion is attached to the circuit board to make contact with the housing.
