BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to speakers and, more particularly, to a combination speaker enclosure mounting structure, which enables a number of speaker enclosures to be horizontally and/or vertically connected in series. 
   2. Description of the Related Art 
   Regular speaker enclosures include square design, rectangular design, as well as spherical design. When linking multiple speaker enclosures, people may simple arrange speaker enclosures in a stack. Further, there are speaker support devices that enable the user to adjust the angular position of the speakers. However, the adjustment is limited to one single direction only. 
   It is therefore a demand for a combination speaker enclosure mounting structure that enables multiple speaker enclosures to be connected to one another in different directions and freely adjusted to different angular positions. 
   SUMMARY OF THE INVENTION 
   The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a combination speaker enclosure mounting structure, which enables multiple speaker enclosures to be connected together horizontally as well as vertically. It is another object of the present invention to provide a combination speaker enclosure mounting structure, which enables the user to adjust the position of the speaker enclosures in different directions. 
   According to one aspect of the present invention, the combination speaker enclosure mounting structure comprises a plurality of enclosures. Please refer to a spherical shape of enclosure is represented as showing that each spherical enclosures having two crossed openings at two opposite sides, and two receptacles respectively disposed in the crossed opening, and a plurality of fasteners adapted to secure the spherical enclosures to one another, for enabling the spherical enclosures to be adjusted to the desired angle relative to one another. According to another aspect of the present invention, each fastener comprises a first locating plate fastened to one spherical enclosure, a second locating plate fastened to a second spherical enclosure, and a ball supported in a ball socket between the first locating plate and the second locating plate for enabling the joined two spherical enclosures to be turned relative each other to adjust the respective angular position.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referring to FIGS.  1 ˜ 5 , a combination speaker enclosure mounting structure is shown comprised of two spherical enclosures  1  each formed of a meshed member  11 , a face panel  12 , and a back shell  13 , and a fastener  2  joining the spherical enclosures  1 . Each spherical enclosure  1  has two crossed openings  14  and  15  formed in the face panel  12  and the back shell  13  at two opposite sides, for example, the top and bottom sides, two receptacles  16  and  17  respectively disposed on the inside corresponding to the crossed openings  14  and  15 , a tapered surface portion  141  corresponding to one crossed opening  14 , and a plurality of vertical stop rods  18  respectively suspended inside the crossed openings  14  and  15 . 
   The fastener  2  is comprised of a first locating plate  21 , which comprises a plurality of locating pegs  211  radially protruded from the periphery and a plurality of axially extended screw holes  212 , a second locating plate  22 , which comprises a plurality of locating pegs  221  radially protruded from the periphery and an axially extended center screw hole  222 , a ball socket  24 , which comprises an axially extended center through hole  252 , an annular top flange  25  extended around the center through hole  252 , and a plurality of mounting holes  251  equiangularly spaced in the annular top flange  25 , a ball  23  received in the center through hole  252  of the ball socket  24  between the first locating plate  21  and the second locating plate  22 , a washer  26  supported between the second locating plate  22  and the ball socket  24 , a fixed stem  231  perpendicularly extended from the periphery of the ball  23  and inserted through the center through hole  261  of the washer  26 , a tie screw  27  threaded into the center screw hole  222  of the second locating plate  22  and a bottom screw hole (not shown) of the stem  231  to fix the ball  23 , the ball socket  24 , the washer  26 , and the second locating plate  22  together, a cushion  28  supported between the ball  23  and the first locating plate  21 , a spring washer  29  supported between the cushion  28  and the first locating plate  21 , and a plurality of tie screws  30  respectively threaded into the screw holes  212  of the first locating plate  21  and the mounting holes  251  of the ball socket  24  to fix the first locating plate  21  to the ball socket  24 . 
   Referring to  FIGS. 6 and 7 , the first locating plate  21  and the second locating plate  22  are respectively inserted through the bottom crossed opening  15  of one spherical enclosure  1  and the top crossed opening  14  of a second spherical enclosure  1  into the corresponding receptacles  17  and  16 , and then the two spherical enclosures  1  are rotated relative to each other in reversed directions to force the locating plates  21  and  22  into friction engagement with the respective receptacles  17  and  16 . When rotating the spherical enclosures  1  relative to each other, the locating pegs  211  and  221  will be stopped at the respective vertical stop rods  18  inside the corresponding crossed openings  14  and  15  to limit the angle of rotation between the spherical enclosures  1 . Further, when rotating the spherical enclosures  1  relative to each other, the locating pegs  221  of the second locating plate  22  are moved over the tapered surface portion  141  of the corresponding spherical enclosures  1 , thereby causing the fastener  2  to be tightly fastened to the spherical enclosures  1 , and therefore the two spherical enclosures  1  are secured together. After installation of speakers (not shown) in the spherical enclosures  1 , electric connectors  3  and ribbon cables  31  are installed to link the speakers and to connect the speakers to the audio source. Further, because the ball  23  can be rotated in the ball socket  24 , the user can adjust the angular positions of the spherical enclosures  1 . 
   Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
