     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]     Referring to  FIGS. 1-4 , a fragrance emitting and stopping device for a cell phone in accordance with a first embodiment of the present invention is shown and comprises: an activator  10 , a slide device  20 , a positioning member  30  and fragrance bottle  40  arranged in the housing of a cell phone, and a fragrance-releasing hole  50  formed on the cell phone.  
         [0019]     The activator  10  is an electromagnetic iron (a soft iron wound with wires and serves to convert electric power into magnetic force), when a call comes in, the activator  10  will be turned on and generate an electromagnetic field, and if there is no coming call, no electromagnetic field will be generated.  
         [0020]     The slide device  20  comprises a permanent magnetic iron  21  disposed on the slide base  22 , and the permanent magnetic iron  21  is located toward the activator  10 . On the slide base  22  is formed a through hole  23  that will be caused to move when the slide base  22  is moved by the electromagnetic effect (attraction or repulsion) between the permanent magnetic iron  21  of the slide device  20  and the activator  10 .  
         [0021]     The positioning member  30  is located toward the activator  10  and arranged on the same side of the slide base  22  of the slide device  20 . When an electromagnetic action is produced between the permanent magnetic iron  21  of the slide device  20  and the activator  10 , and the slide device  20  is caused to move, at this moment, the positioning member  30  will act as a limiter to stop further movement of the slide device  20 .  
         [0022]     The fragrance bottle  40  serves to contain solid fragrance substance and is located at a side of the through hole  23  on the slide base  22  of the slide device  20 , the fragrance releasing hole  50  is located at another side of the through hole  23 , and the through hole  23  can be moved to a position aligned to the mouth of the fragrance bottle  40 .  
         [0023]     When a call comes in, the cell phone will produce a detection signal and send current to the activator  10 , and the activator  10  will produce an electromagnetic force. Since the permanent magnetic iron  21  of the slide device  20  is located opposite the activator  10 , the magnetic force generated by the activator  10  will repel the magnetic force of the magnetic iron  21 , and as a result, the slide device  20  will be caused to move. At this moment, the positioning member  30  will stop the slide device  20  at a position at which the through hole  23  on the slide device is aligned with the mouth of the fragrance bottle  40 . Therefore, the fragrance can be released from fragrance bottle  40  through the through hole  23  and the fragrance-releasing hole  50 .  
         [0024]     When there is no coming call, the cell phone doesn&#39;t produce detection signal, and the activator  10  will not produce any electromagnetic force. Since the permanent magnetic iron  21  of the slide device  20  is located opposite the activator  10 , they will be attracted to each other. Consequently the through hole  23  of the slide base  22  of the slide device  20  will move back to its original position that is offset from the fragrance bottle  40 , and at this position, the cell phone stops releasing fragrance from the fragrance bottle  40 .  
         [0025]     Referring to  FIGS. 5-7 , a fragrance emitting and stopping device for a cell phone in accordance with a second embodiment of the present invention is similar to that of the first embodiment, except the following aspects:  
         [0026]     There are three positioning members  30  in this embodiment (positioning members  30  are permanent magnetic iron for example) and they are located opposite a first electromagnetic iron A, a second electromagnetic iron B and a third electromagnetic iron C that are arranged at certain intervals. For example, the cell phone can differentiate three different signals and output current the first, second and third electromagnetic irons A, B and C, respectively, causing repulsion of the three electromagnetic irons A, B and C relative to the positioning members  30 . furthermore, there are three fragrance bottles  40 , the three electromagnetic irons A, B and C are movable relative to the fragrance bottles  40 , and the through hole  23  on the slide base  22  of the slide device  20  is also movable relative to the fragrance bottles  40 .  
         [0027]     When a call comes in, the cell phone will produce a detection signal and send current to the activator  10 , and the activator  10  will produce an electromagnetic force. Since the permanent magnetic iron  21  of the slide device  20  is located opposite the activator  10 , the magnetic force generated by the activator  10  will repel the magnetic force of the magnetic iron  21 , and as a result, the slide device  20  will be caused to move and the through hole  32  will move along with the slide device  20 . At this moment, when the cell phone produces a detection signal and sends current to one of the three electromagnetic irons A, B and C, causing repulsion of the three electromagnetic irons A, B and C relative to the positioning members  30 . The positioning members  30  will stop the slide device  20  to a position at which the through hole  23  on the slide base  22  of the slide device  20  is aligned to one of the mouth of the fragrance bottles  40 . Therefore, the fragrance can be released from one of the fragrance bottles  40  through the through hole  23  and the fragrance-releasing hole  50  (in this embodiment, the three fragrance bottles  40  is received with different fragrance, therefore, the cell phone can release different fragrances according to predetermined setting).  
         [0028]     When there is no coming call, the cell phone doesn&#39;t produce detection signal, and the activator  10  will not produce any electromagnetic force. Since the permanent magnetic iron  21  of the slide device  20  is located opposite the activator  10 , they will be attracted to each other, and the three electromagnetic irons A, B and C will also be attracted to the positioning members  30 . Consequently the through hole  23  of the slide base  22  of the slide device  20  will move back to its original position that is offset from the fragrance bottle  40 , and at this position, the cell phone stops releasing fragrance from the fragrance bottle  40 .  
         [0029]     Referring to  FIGS. 8-10 , a fragrance emitting and stopping device for a cell phone in accordance with a third embodiment of the present invention is similar to that of the first embodiment, except the following aspects:  
         [0030]     There are three fragrance emitting and stopping devices in this embodiment, and the fragrance bottles  40  are packed with different fragrances. When a call comes in, and according to predetermined setting, cell phone can differentiate three different detection signals and output current to the three fragrance emitting and stopping devices, respectively. The three activators  10  will be turned on and produce electromagnetic force, making the through hole  23  on the slide base  22  of the slide device  20  align with the mouth of the fragrance bottle  40 . Therefore, the cell phone can release different fragrances as needed.  
         [0031]     If there is no coming call, the cell phone doesn&#39;t produce detection signal, the cell phone will stop releasing fragrance from the fragrance bottle  40 .  
         [0032]     While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
