as shown in fig. 7, the link mechanism 3c includes a first link 3c1, a second link 3c2 and a third link 3c3 which are sequentially rotatably connected, one end of the first link 3c1, which is far away from the second link 3c2, is rotatably connected to the left support base 5, and is parallel to the rotation axis of the left support base 5 around the rotation axis of the left support base 3a around the rotation axis of the left support base 5, a hinge shaft 3a1 is provided on the inner bottom of the left support base 3a, the middle part of the second link 3c2 is rotatably connected to the hinge shaft 3a1, and one end of the third link 3c3, which is far away from the second link 3c2, is rotatably connected to the outer bottom of the inner casing 3b 2. Since the first link 3c1 is parallel to and not coaxial with the rotation axis of the left rotary seat 3a about the left support seat 5 about the rotation axis of the left support seat 5, when the left sound box 3 is turned forward and opened, the first link 3c1 pulls the second link 3c2 to rotate clockwise about the hinge shaft 3a1, so that the inner housing 3b2 has a tendency to move outwards, thereby driving the left sound chamber assembly 3b to slide outwards with respect to the left rotary seat 3 a.
In order to ensure that the third connecting rod 3c3 can drive the left sound cavity assembly 3b to effectively slide outwards in an initial state and avoid shaking of the connecting rod mechanism 3c during operation, a torsion spring 3c4 is arranged at a position where the second connecting rod 3c2 is rotationally connected with the third connecting rod 3c 3.
As shown in fig. 8 and 9, in order to prevent the left sound cavity assembly 3b from being completely separated, a limit boss 3a1 is provided on an inner bottom of one end of the left rotary seat 3a far away from the left support seat 5, a limit clamping tongue 3b4 is provided on an outer bottom of the outer casing 3b1, the limit clamping tongue 3b4 is adapted to the limit boss 3a1 and is located on the same section of the left sound box 3, and when the left sound cavity assembly 3b slides to the outermost end, the limit boss 3a1 is abutted on the limit clamping tongue 3b 4.
The right sound box 4 has the same structure as the left sound box 3.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and that many similar changes can be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
