Description:
FIELD OF THE INVENTION  
         [0001]    This invention relates to a modular mobile communication device for providing one-on-one communication function and particularly a device that adapts modular design for enhancing expandability of mobile communication devices.  
         BACKGROUND OF THE INVENTION  
         [0002]    The increasing inter-person activities in modern times have resulted in rapid growth of mobile phone systems and handsets. Almost any one can make one-on-one communication economically at two locations nowadays. As a result, mobile phone has become a very popular personal communication device.  
           [0003]    The mobile phones now being used mostly have a body about the size of a human palm. The body includes a communication process unit for performing one-on-one communication. The front side of the body has, from top to bottom, an antenna, a display unit and a plurality of button keys. At the rear side of the body, there is a chamber for housing a Subscriber Identity Module (SIM) Card and a rechargeable battery. The antenna is for receiving and emitting signals, the button keys include numeral keys (or character keys), receiving key, cutoff key and selection key for respectively input telephone phone number and data, dialing phone number, receiving incoming signal or cutting off incoming signal. The display unit may display data regard the communication system, receiving signal power, battery power and built-in information and the like. Almost all the presently available mobile phones employ Liquid Crystal Display (LCD) unit for display which is a delicate device and cannot withstand heavy pressure or impact. Incidental dropping of the mobile phone could easily cause damage of the LCD unit and result in not functioning of the display device even though the communication function of the mobile phone remains intact. In such an situation, users have to buy a new mobile phone for replacement.  
           [0004]    Another mobile phone purchasing consideration for users is the amount of standby time available. There are generally two ways to increase the standby time frame. One is to increase capacity of the rechargeable battery. Another is to reduce power consumption during the standby time period. For the ordinary mobile phones, the most power consuming item during the standby time is the display device because it continuously shows the data. Hence to reduce power consumption of the display device is one way to increase standby time frame.  
           [0005]    Because of fast paced technology innovation and fierce competition among the mobile phone manufacturers, a prolific of new and function-rich mobile phones have been developed and introduced on the market constantly. For instance, it has evolved from a simple one-on-one communication to Wireless Application Protocol (WAP) mobile phones which are able to access and browse Internet. However the small size display device on the mobile phone is a severe limitation for WAP applications. A detachable and larger size display device would be a great help to resolve this problem.  
         SUMMARY OF THE INVENTION  
         [0006]    It is therefore an object of this invention to provide a modular mobile communication device that constitutes a detachable communicating device and display device.  
           [0007]    The communication device according to this invention includes a communication module and a display module. The communication module may function independently to perform one-on-one communication. The display module may be selectively engaged with or detached from the communication module for displaying data processed by the communication module. In the event of the display module being damaged, users may replace only the display module without the need to buy a whole new set of mobile phone. Furthermore, during standby time, the display module may be detached from the communication module for reducing power consumption and increasing useable time of the communication module. Moreover, users may select larger size display module for WAP applications and browsing WAP sites information.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0016]    Referring to FIGS. 1 and 2, the modular mobile communication device according to this invention includes a communication module  10  and a display module  20 .  
         [0017]    The communication module  10  includes at least a control process unit  11 , an antenna  12 , a sonic input unit  13 , a sonic output unit  14 , a plurality of button keys  15  and a first connection port  16  (also shown in FIG. 3. The technical principle and electric circuit for the construction sets forth above are known in the art, their details will be omitted herein). The control process unit  11  is for managing data and processing signals. The antenna  12  links to the control process unit  11  for receiving or emitting signals. The sonic input unit  13  is a microphone located at a lower end of the communication module  10  and is linked to the control process unit  11  for receiving user&#39;s verbal sound. The sonic output unit  14  is a speaker located at an upper end of the communication module  10  and is linked to the control process unit  11  for the user to hear the receiving sound. The button keys  15  include numeral keys (or character keys), receiving key, cutoff keys and selection keys linked to the control process unit  11  for input telephone number and telephone directory data, dialing outgoing telephone, receiving incoming telephone, or cutting off incoming signals. The first connection port  16  links to the control process unit  11  for establishing communication path for input or output signals. All the foregoing units are powered by a rechargeable battery  30  and form an independent assembly which is able to perform one-on-one communication.  
         [0018]    The display module  20  is a separated assembly includes a display unit  21  and a second connection port  22 . The display unit  21  is a LCD display device for displaying data. The second connection port  22  links to the display unit  21  for establishing communication path for output or input signals.  
         [0019]    Referring to FIGS. 1, 2 and  3 , the communication module  10  and display module  20  are independent elements. The communication module  10  may perform one-on-one communication by itself. The display module  20  may be selectively engaged with the communication module  10  through coupling the second and first connection port  22  and  16 . The rechargeable battery  30  provides all the electric power needed. The display module  20  can display data processed by the control process unit  11 .  
         [0020]    Because this invention adapts a detachable construction, users may select a combined or detached configuration of the communication module  10  and display module  20  to suit their needs and desires. When users want more standby time, they can choose an assembly without the display module  20  for reducing battery power consumption. In case the display module  20  is damaged, users may buy another display module  20  at a lower cost for replacement without the need to buy a whole new set of the mobile phone at a higher price.  
         [0021]    Referring to FIG. 4 for another embodiment of this invention, for increasing the standby time, an extra rechargeable battery  30   a  may be added to the display module  20  for supplying power needed in the display module  20 , then the standby time of the communication module  10  may be increased.  
         [0022]    [0022]FIG. 5 illustrates yet another embodiment in which the display module  20  includes a sonic input unit  23  engaged to the second connection port  22 . When the communication module  10  is coupled with the display module  20 , the total mobile phone set has a greater length. Hence user may hear the incoming voice from the sonic output unit  14  at the communication module  10  and speak to the sonic input unit  23  at the display module  20  at more focused distances to the ear and mouth thereby to make communication more effective and comfortable.  
         [0023]    As the modular mobile communication device of this invention adapts a detachable design and construction, the communication module  10  may also be coupled with other electronic data process devices. FIG. 6 shows an embodiment example in which the communication module  10  is coupled with a digital camera  40  through the first connection port  16 . The image taken by the digital camera  40  may be transmitted to an external device desired through the communication module  10 . FIG. 7 shows yet another embodiment example in which the communication module  10  is coupled with a MP3 device  50  for down loading MP3 formatted music through the communication module  10 . The expandability of the communication module  3  thus may be greatly enhanced.
