Abstract:
The invention provides a loudspeaker mounting mechanism capable of adjusting the loudspeaker angle for generating stereo surrounding sound effect, or meeting personal sound effect favorites. By means of hinge links the loudspeaker to the display in a manner that the loudspeaker can be rotated relatively to the display, instead of being fixed as conventional attached loudspeakers.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The invention generally relates to a loudspeaker rotary mechanism applicable to a display, and in particular relates to a loudspeaker mechanism capable of adjusting the mounting angle.  
         [0003]     2. Description of the Related Art  
         [0004]     Attachable loudspeakers of prior arts are mainly of fixed types. The loudspeaker is fixedly hung on sides of the display. Even if the loudspeaker can be adjusted, it is limited to a specific angle, inconvenient to use or poor in sound effect.  
         [0005]     Moreover, televisions nowadays emphasize much on their audio effects. The conventional fixedly mounted loudspeaker is unable to satisfy user&#39;s requirements on the sound quality. Therefore, the invention intends to provide a pivotally mounted loudspeaker that can be freely adjusted by user in suitable angles so as to suit the user&#39;s needs for better sound quality.  
       SUMMARY OF THE INVENTION  
       [0006]     The object of the invention is to solve the problem of conventional fixedly mounted loudspeaker and provide a loudspeaker mounting mechanism that can be adjusted with the angles to produce a better sound field.  
         [0007]     The invention relates to a loudspeaker mechanism capable of adjusting the mounting angle for generating stereo surrounding sound effect.  
         [0008]     The loudspeaker is mounted outside a display, through a rotary mechanism. The rotary mechanism hangs the loudspeaker onto the display through a hinge. The hinge makes the loudspeaker adjustable with its angles for building different stereo sound effects, and solving the problem of conventional stationary loudspeakers.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0016]     Televisions nowadays focus not only on their image quality, but also their sound effects. From a physical view, sound transmission depends on the sound wave and the media. The sound effect of a loudspeaker is not only influenced by the box volume and the material quality, but also the direction and angle that it faces to.  
         [0017]     Similar to the angle of view of a display, the sound effect of a loudspeaker is also relative to its angle to build the better stereo surrounding sound effect. The novel design of the invention allows the user changing the angle of the suspended loudspeakers and obtaining the required sound effects.  
       First Embodiment  
       [0018]     An embodiment of the invention is applied to a display. As shown in  FIG. 1 , a first embodiment of the invention. A loudspeaker rotary mechanism comprises a display  10 , at least an attachable loudspeaker  20 , and a rotary mechanism. The rotary mechanism is a hinge  30  which composed of two members  31  and  32 . Said first member  31  connects with an axle and a second member  32  without an axle. Said first member  31  connects with a side of said display  10  and said second member  32  connects with a side of said attachable loudspeaker  20 . Said hinge  30  links said loudspeaker  20  to said display  10  in a manner that said loudspeaker  20  can be rotated relatively to said display  10 .  
         [0019]      FIG. 2  is a perspective view of said hinge  30  applied in the rotary loudspeaker of the invention. There is a rotating center-axle (A). A least a Belleville spring  33  is installed on said rotating center-axle (A) for providing a suitable torsion and controlling the duration of said hinge  30 . Said Belleville spring, as shown in  FIGS. 3A and 3C , is a thin cone-like member having a central hole similar to a spacer. Said Belleville spring generates a large resilient force or resilient ratio on the axial-direction as  FIG. 3B  shown. By means of ratio change of the cone height (H) to the thickness (t) to get is different Loading-Deflection characters of said Belleville spring. By stacking an amount of such springs in the same or reversed direction can enlarge the load capacity. In addition, the outer diameter and inner diameter of said Belleville spring  33  are indicated by OD and ID.  
         [0020]     Therefore, as shown in  FIG. 2 , by being applied with a suitable amount of Belleville springs on said rotating center-axle (A), said hinge  30  linking said loudspeaker  20  and said display  10  is maintained with a suitable torsion so as to keep said hinge  30  revolvable and stay at any required position and durable for a long time use. The adjustment lets said loudspeaker  20  stay at any suitable position and provide better sound effects.  
         [0021]     As shown in  FIG. 1  and  FIG. 4 , the embodiment of main components said display  10 , said loudspeaker  20 , and said hinge  30 . To complete said components as a whole, said first member  31  of said hinge  30  connects with a side of said display  10 ; at least one attachable loudspeaker  20  connects with said second member  32  of said hinge  30 ; said display  10  connects with at least one attachable loudspeaker  20 . In  FIG. 4 , said loudspeaker  20  is rotated backward with an angle θ relative to said display  10 . The rotation angle is changeable by user according to user&#39;s favorites of sound effects.  
       Second Embodiment  
       [0022]     1.  FIG. 5  shows a second embodiment of the invention. A loudspeaker rotary mechanism comprises a display  10 , at least an attachable loudspeaker  20 , and a rotary mechanism. Said rotary mechanism is a hinge  30  which composed of two members  31  and  32 . Said first member  31  with an axle and said second member  32  without an axle. Said first member  31  connects with a side of said display  10  and said second member  32  connects with a side of said attachable loudspeaker  20 . Said hinge  30  links said loudspeaker  20  to said display  10  in a manner that said loudspeaker  20  can be rotated relatively to said display  10 .  
         [0023]     In  FIG. 6 , said loudspeaker  20  is rotated forward with an angle  4 ) from said display  10 . Said rotation angle is changeable by user according to user&#39;s favorites of sound effects.  
         [0024]     To achieve the best surrounding effect, the user can add multiple loudspeakers (such as heavy bass or high bass speakers) on both sides of the display and adjust angles of the loudspeakers. In other words, the number of loudspeakers is not limited. In addition, to be more convenience for users, a fixing pin (not shown in the drawing) can be formed on said hinge  30 . Said fixing pin can let user fast adjust said rotation angle in certain angles.  
         [0025]     The display in the aforesaid embodiment is a plasma television, an LCD TV, or other displays.  
         [0026]     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
