BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrist watch, and more particularly, to a multifunction wrist watch supporting communication service with a mobile communication terminal in addition to a unique function of the watch.

Various auxiliary devices have been developed with the development of mobile communication terminals, and one of them is a wireless headset which is an auxiliary device of a mobile phone. Wireless headsets eliminate the need for users to talk directly to a cell phone. This allows the user to talk using a wireless headset even when the phone is far away. It's much easier because you don't have to carry the phone yourself, and it also solves the problem of exposure to electromagnetic waves that affect your body. But if you don't wear a wireless headset, you'll need to bring it with you. In general, I use a wireless headset a lot when listening to MP3, otherwise I do not wear a wireless headset. Also, while wearing a wireless headset, behavior is limited. For example, in the case of vigorous sports such as soccer or basketball, not only is it cumbersome but also easily escapes. As a result, wireless headsets are not always worn. When a call comes in a non-wearing state, it is cumbersome to answer the call after wearing the wireless headset, so that the call is usually directly received by a mobile phone. However, there is a problem that the voice of the other party is difficult to hear when the ambient noise is large when directly talking on the mobile phone. In addition, as mentioned above, it is exposed to electromagnetic waves.

On the other hand, the mobile phone sets the time with the information by the GPS (Global Positioning System), thereby providing accurate time information. On the other hand, since the time is set by a user's manual operation, the general clock has a problem of providing incorrect time information. And since the mobile phone is not provided in the form of wearing, there is a high risk of loss due to the owner's carelessness.

The present invention is derived from this background, and aims to provide a multi-function wrist watch that can be used as a wireless headset of a mobile communication terminal and at the same time can accurately transmit the other party's voice regardless of ambient noise.

It is also an object of the present invention to provide a multi-function wrist watch that can automatically display the correct time setting.

In addition, an object of the present invention is to provide a multifunctional wrist watch capable of preventing the loss of a mobile communication terminal.

Multifunction wristwatch according to an aspect of the present invention for achieving the above object comprises a short-range communication module capable of short-range communication with the mobile communication terminal, and transmits and receives voice data with the mobile communication terminal through the short-range communication module. Furthermore, the multifunction wristwatch according to the present invention outputs the voice of the other party transmitted from the mobile communication terminal through the bone conduction speaker. According to a characteristic aspect of the present invention, the bone conduction speaker is provided to be exposed to a predetermined position under the watch band so as to be in close contact with the wearer's bone in a watch wearing state.

As described above, the multi-function wristwatch according to the present invention can be utilized like a wireless headset of a mobile communication terminal, and unlike a general wireless headset, there is no fear of being separated even if a vigorous exercise is carried out in a worn state, and it is not cumbersome. In addition, since the other party's voice is directly transmitted to the watch cell's auditory cell using a bone conduction speaker, the other party's voice can be accurately transmitted even if the ambient noise is severe.

The multifunction wristwatch according to an additional aspect of the present invention receives time information of a mobile communication terminal through a short range communication unit and sets a time. As a result, even the wrist watch can display the correct time.

The multi-function wristwatch according to an additional aspect of the present invention outputs a message about the terminal loss warning when the communication area is out of the short range communication state with the mobile communication terminal. Accordingly, a watch wearer according to the present invention may recognize a loss warning of a mobile communication terminal to prevent loss.
