         [0015]    It is noteworthy that the configuration of the upper casing  17  and the bottom plate  12  is not limited to this embodiment. In other alternative embodiments, the upper casing, the bottom plate, and the opening can be designed in other shapes. Also, the numbers of the speakers  15  and the first through holes  176  are not limited to this embodiment, but should be set depending on requirements. 
         [0016]    In particular, the bottom plate  12  includes three positioning columns  122  extending toward the upper casing  17 . Each positioning column  122  defines a first through threaded hole  123 . The upper casing  17  defines three fastener-receiving columns  173  extending toward and aligned with the corresponding positioning columns  122 . The upper casing  17  and the bottom plate  12  are connected by inserting three fasteners (not shown) through the corresponding first through threaded holes  123  and into the corresponding fastener-receiving columns  173 . Also, the upper casing  17  and the bottom plate  12  can be combined by other methods, such as, structural engagement or adhesive. 
         [0017]    The bottom plate  12  further includes a supporter  143  disposed between the two speakers  15 . The upper casing  17  includes a rib  174 . The rib  174  is a plate extending toward the bottom plate  12  and positioned between the first through holes  176  and the first hole  177 . The rib  174  defines a cutout  175 . The inverter tube  16  is supported by the supporter  143  and extends through the cutout  175  to the second through hole  177 . Thus, the inverter tube  16  is secured within the resonant chamber by the supporter  143  and the rib  174 . Of course, the inverter tube  16  can be fixed in the resonant chamber by other methods in alternative embodiments. 
         [0018]    The protective net  18  is pasted on the upper casing  17 , covering the first through hole  176  and the second through hole  178  for allowing sound to exit but blocking the entry of dust. To avoid the protection sheet  18  adversely affecting the appearance and interfering with the handling of the sound box  100 , the upper casing  17  defines a sunken surface  17   b . The protection sheet  18  fittingly fills the sunken surface  17   b.    
         [0019]    The bottom plate  12  defines a groove  121  in a surface  12   a  facing away from the upper casing  17 . The battery  13  is fittingly received in the groove  121 . The cover  11  covers the surface  12   a  to secure the battery to  13  to the bottom plate  12 . In particular, the bottom plate  12  also includes an electrical contact  124  that is disposed in the groove  121  and electrically connected to the PCB  14 . The battery  13  is electrically connected to the PCB  14  by the electrical contact  124  and supplies power for the PCB  14 . The battery  13  can be a rechargeable battery and recharged by the external power source by the power connector  141 . 
         [0020]    The bottom plate  12  defines two engagement-receiving portions  125  at one side of the groove  121  and a blind threaded hole  126  at an opposite side of the groove  121 . The cover  11  is a flat board and includes a front surface  110  and a back surface  111  opposite to the front surface  110 . The back cover  11  includes two engagement portions  112  disposed on the front surface  110  corresponding to the engagement-receiving portions  125 . The back cover  11  also defines a second threaded through hole  113  through the front surface  110  and the rear surface  111 . The cover  11  is secured to the bottom plate  12  by engaging the two engagement portions  112  with the engagement-receiving portions  125  and inserting a fastener (not shown) through the second through threaded hole  113  and into the blind threaded hole  12 . Of course, the cover  11  can be secured to the bottom plate  12  by other methods. 
         [0021]    The cover  11  includes two first connecting plates  21  extending upwards from the back surface  111 , adjacent to an end of the cover  11 . Each first connecting plate  21  defines a first connecting hole  210 . The two first connecting holes  21  are aligned with each other. The clip  20  includes a clipping plate  24 , a shaft  23 , and a coil spring  22 . The clipping plate  24  includes two second connecting plates  240  extending upward from a surface of the clipping plate  24 , adjacent to an end of the clipping plate  24 . Each second connecting plate  240  defines a second connecting hole  241 . The second connecting holes  241  are aligned with each other. The distance between the second connecting plates  240  is slightly farther than between the first connecting plates  21 . The shaft  23  extends through one second connecting hole  240 , one first connecting hole  210 , the coil spring  22 , the other first connecting hole  210 , and the other second connecting hole  240  in sequence. Thus, the clipping plate  24  is connected to the cover  11 . The coil spring  22  is configured for applying a torsional force to the clipping plate  24  so that an end of the clipping plate  24  opposite to the second connecting plate  240  abuts the cover  11 . In this embodiment, the clipping plate  24  further includes two gripping teeth  241  formed at the end of the clipping plate  12  opposite to the second connecting plates  240  to increase a gripping force of the clip  20 .
