Description:
FIELD OF THE INVENTION  
       [0001]     This invention relates to portable electronic device, and more particularly, to a multifunctional portable electronic device.  
       DESCRIPTION OF RELATED ART  
       [0002]     With the development of wireless communication technology and information processing technology, multifunctional portable personal communication devices, such as mobile phones with cameras, are very popular in recent years, since these devices provide users with not only voice communication, but also photographic functions.  
         [0003]     However, the conventional mobile phones are generally pocketed by the users. Therefore, the users may fail to find incoming calls or messages right away when the mobile phones are set in vibration modes or the users are situated in a noisy environment. In addition, the conventional mobile phone is generally pocketed instead of being fastened to the body of the user. Thus, the mobile phone is easy to get lost.  
         [0004]     What is needed, therefore, is to provide an improved multifunctional portable electronic device.  
       SUMMARY OF INVENTION  
       [0005]     A preferred embodiment provides a multifunctional portable electronic device including a main body and a clasp. The main body houses a printed circuit board, and a power supply module for supplying power to the printed circuit board, the printed circuit board having a radio frequency module mounted thereon for providing a wireless communication function. The clasp is coupled to the main body for clasping a wrist of a user.  
         [0006]     Compared with the conventional mobile phones, the multifunctional portable electronic device according to the preferred embodiment is equipped with a clasp, which makes the multifunctional portable electronic device be prevented from lost by way of holding the multifunctional portable electronic device on a user&#39;s wrist. In addition, because the wrist is a sensitive part of the user, therefore the user can find incoming calls or messages right away.  
         [0007]     Other advantages and novel features will become more apparent from the following detailed description of embodiments when taken in conjunction with the accompanying drawings.
