Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to earpiece fixing structures and, particularly, to an earpiece fixing structure used in electronic devices. 
         [0003]    2. Description of Related Art 
         [0004]    With rapid development of information technology, electronic devices, such as cellular phones, personal digital assistants (PDA), and so on, are becoming increasingly more popular. Consequently, users may pay more attention to the suitability of the electronic devices for daily use. Thus, printed circuit boards of the electronic devices should stably connect to electronic components of the electronic device. 
         [0005]    A typical electronic device often includes a main body having a receiving slot, a cover, a printed circuit board, and an earpiece module. The earpiece module and the printed circuit board are received in the receiving slot. The cover latches to the main body and presses the printed circuit board and the earpiece module in the receiving slot, thereby electronically connecting the printed circuit board to the earpiece module. However, if the cover becomes loose, the printed circuit board and the earpiece module will not be kept in good contact with each other, thereby affecting normal operation of the electronic device. 
         [0006]    Therefore, there is room for improvement within the art.

The earpiece fixing structure  16  is configured for fixing the earpiece module  12  and the flexible printed circuit board  15  in the main body  10 . 
         [0012]    The main body  10  is configured for receiving electronic components, and includes a receiving portion  11  having a bottom portion  112 , a fixing seat  115 , and a latching post  116 . The fixing seat  115  is positioned in the bottom portion  112  adjacent to an end of the main body  10 , and configured for receiving the earpiece module  12 . The fixing seat  115  includes a first wall  1151 , a second wall  1152  opposite to the first wall  1151 , a third wall  1153 , a fourth wall  1154  opposite to the third wall  1153 , a first block  1156 , a second block  1157  and a third block  1158 . The first block  1156  and the second block  1157  extend from near opposite edges at a same side of the third wall  1153 . The third block  1158  is positioned on the fourth wall  1154  and faces to the first block  1156  and the second block  1157 . The latching post  116  is positioned on the bottom portion  112  adjacent to the fourth wall  1154 . 
         [0013]    The earpiece module  12  includes two spring clips  121  symmetrically positioned on a same side thereof. The spring clips  121  are configured for connecting to the flexible printed circuit board  15 . 
         [0014]    The flexible printed circuit board  15  defines a through hole  151 , a mounting hole  152 , a first gap  153 , a second gap  154 , and a plurality of contacting points (not shown) configured for connecting to the spring clips  121 . The through hole  151  is matchable with the latching post  116 . The mounting hole  152  is adjacent to the through hole  151 . The first gap  153  and the second gap  154  are spaced from each other, and defined in a same edge of the flexible printed circuit board  15 . 
         [0015]    The earpiece fixing structure  16  includes a cover  160 , and further includes a first latching portion  161 , a second latching portion  162 , a third latching portion  163 , and a fixing portion  164  all similar in structure. Each of the latching portions  161 ,  162 ,  163  includes a main sheet  168  defining a latching hole  165  and a guiding sheet  166  bent from the main sheet  168 . The latching hole  165  is matchable with any of the first block  1156 , a second block  1157 , and a third block  1158 . The first latching portion  161  and the second latching portion  162  are bent from a same lateral side of the cover  160  and are spaced from each other. The third latching portion  163  is bent from another lateral side of the cover  160  opposite to the first latching portion  161 . The fixing portion  164  is bent from a lateral side of the cover  160  adjacent to the lateral side forming the third latching portion  163 . The fixing portion  164  is L-shaped, and includes a first sheet  1641  and a second sheet  1642  perpendicularly bent away from the first sheet  1641 . The second sheet  1642  defines a locating hole  1643  therein. 
         [0016]    The fixing post  17  is positioned on the bottom portion  112  adjacent to the second wall  1152 . The fixing post  17  is engagable in the locating hole  1643 . 
         [0017]    Referring to the drawing,  FIG. 3 , in assembly, the earpiece module  12  is placed into the fixing seat  115 . The flexible printed circuit board  15  covers the earpiece module  12 . Meanwhile, the contacting points electronically connect to the spring clips  121 . The latching post  116  passes through the through hole  151 . The mounting hole  152  corresponds to the third block  1158 , thereby the third block  1158  being exposed out from the mounting hole  152 . The cover  160  covers the flexible printed circuit board  15 . The first block  1156  and the second block  1157  respectively pass the first gap  153  and the second gap  154 , further engage into each latching hole  165  of the first latching portion  161  and the second latching portion  162 . The third latching portion  163  passes through the mounting hole  152  and latches to the third block  1158 . The fixing post  17  engages in the locating hole  1643 . 
         [0018]    The earpiece fixing structure  16  is latched to the fixing seat  115  and configured for fixing the earpiece module  12  and the flexible printed circuit board  15  on the main body  10  of the electronic device. The earpiece fixing structure  16  is configured to prevent the earpiece module  12  from being detached from the flexible printed circuit board  15 . Furthermore, the earpiece fixing structure  16  is simple and takes up little space.
