       FIGS. 1 and 2  illustrate isometric views of one embodiment of a speaker device  100  from two angles respectively. The speaker device  100  can include a cover  10 , an acoustic tuning assembly  20 , an acoustic unit  30 , and a base unit  40 . The acoustic tuning assembly  20  can include a main body  21  and a housing  22  configured to receive the main body  21 . 
     The main body  21  can be a shape of cylinder and includes a first body  211 , a second body  212 , and a groove  213 . The groove  213  is formed between the first body  211  and the second body  212 , and the groove  213  is around a periphery of the main body  21 . The first body  211  includes a bottom surface  2110  and an upper peripheral wall  2112  extending from an edge of the bottom surface  2110 . An opening is defined on one side of the circular away from the bottom surface  2110 . A plurality of match holes  214  are defined on the upper peripheral wall  2112  according to a preset arrangement mode. In at least one embodiment, the match holes  214  number eight, four of them are arranged in a first side of the upper peripheral wall  2112 , and four of them are arranged in a second side opposite to the first side of the upper peripheral wall  2112 . The bottom surface  2110  of the first body  211  defines a plurality of acoustic holes  215  encircling a center point of the bottom surface  2110 . In at least one embodiment, the acoustic holes  215  number six and have a shape of a sector. Each of the acoustic holes  215  includes a side wall  2150  extending from the bottom surface  2110  and away from the first body  211 . 
     Referring to  FIGS. 3 and 4 , the second body  212  includes a lower surface  2120  and a lower circular wall  2122  extending from an edge of the lower surface  2120 . The second body  212  of the main body  21  defines a receiving space  216  formed of the lower surface  2120 , the lower circular wall  2122 , and bottom surface  2110 , for receiving the acoustic unit  30 . The acoustic unit  30  is coupled to the side wall  2150 , and forms a first sound chamber  217  with the bottom surface  2110 . The first sound chamber  217  can be a shape of tubular. The lower surface  2120  of the second body  212  defines a plurality of position holes  218 . In at least one embodiment, the position holes  218  number four, two of them are arranged in a first side of the lower surface  2120  of the second body  212 , and two of them are arranged in a second side of the lower surface  2120  of the second body  212 . A second sound chamber  238  is formed between the bottom surface  2110  and the upper peripheral wall  2112 , and the second sound chamber  238  can communicate with the first sound chamber  217  through the acoustic holes  215 . 
     The housing  22  can be a shape of hollow cylindrical and includes an upper shell  221  and a lower shell  222 . A protruding ring  223  is defined on an inner wall between the upper shell  221  and a lower shell  222  of the housing  22 . The upper shell  221  defines an opening  224  on one side. A plurality of through holes  225  are defined on a side wall  2210  of the upper shell  221 . In at least one embodiment, the through holes  225  number eight, four of them are arranged in one side of the a first side wall  2210  of the upper shell  221 , and four of them are arranged in a second side of the side wall  2210  of the upper shell  221 , which making an arrangement mode of the through holes  225  is the same as that of the match holes  214 . The lower shell  222  includes a bottom  2220  with an opening  227 , and defines an annular receiving space  226  between the bottom  2220  and the protruding ring  223 . The bottom  2220  of the lower shell  222  defines a plurality of protruding portions  228 . In at least one embodiment, the protruding portions  228  number four, two of them are positioned on a first side of the bottom  2220 , and two of them are positioned on a second side of the bottom  2220 . 
     The base unit  40  with a shape of discoid includes a substrate  41  and an edge portion  44  coupled around the substrate  41 . The substrate  41  is higher than the edge portion  44 , and includes a plurality of protruding columns  42 . In at least one embodiment, the protruding columns  42  number four, to follow an arrange mode as two of them are positioned on a first side of the substrate  41 , and two of them are positioned on a second side of the substrate  41 . The edge portion  44  includes a plurality of receiving holes  43 . In at least one embodiment, the receiving holes  43  number four, to follow an arrange mode as two of them are positioned on a first side of the edge portion  44 , and two of them are positioned on a second side of the edge portion  44 . In assemble, the main body  21  is assembled in the housing  22 . The protruding ring  223  is engaged with the groove  213  to enable the housing  22  to rotate relatively to the main body  21 . The substrate  41  of the base unit  40  is received in the opening  227  of the housing  22 , to make the protruding columns  42  coupled to the corresponding position holes  218  of the main body  21 , and the receiving holes  43  are coupled to the corresponding protruding portion  228  of the housing  22 . Thereby, the main body  21  and the housing  22  can be fixed on the base unit  40 . The cover  10  has a shape of circular ring to detachably couple to the main body  21  and the housing  22 , in one side opposite to the base unit  40 . In at least one embodiment, the cover  10  is a gasket foam. 
     In use, when the acoustic unit  30  operates, sound produced by the acoustic unit  30  can be transmitted to outside world from the first sound chamber  217  and the second sound chamber  238 . The through holes  225  of the housing  22  can be rotated relatively to the main body  21 , to make the through holes  225  overlapped partially or completely with the match holes  214 , or non-overlapping with the match holes  214 . 
     When the through holes  225  of the housing  22  are overlapped partially or completely with the match holes  214  of the main body  21  by rotating the housing  22 , a plurality of overlap holes  245  are formed from the through holes  225  and the match holes  214 . Sound from the acoustic unit  30  can be transmitted to outside world through the first sound chamber  217 , the acoustic holes  215 , the second sound chamber  238 , and the plurality of overlap holes  245 . 
     When the through holes  225  and the match holes  214  are non-overlapping with each other by rotating the housing  22 , the sound from the acoustic unit  30  can be transmitted just from the first sound chamber  217 , the acoustic holes  215 , and the second sound chamber  238 . 
     Therefore, the sound from the acoustic unit  30  can be adjusted in variety, through changing an overlap proportion between the through holes  225  and the match holes  214 , which can satisfy people to acquire abundant and various sound effect. 
     While the disclosure has been described by way of example and in terms of the embodiment, it is to be understood that the disclosure is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the range of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
