[0027] Furthermore, the middle of the molded base plate 401 is integrally formed with multiple parallel ribs 402, and the four inner corners of the molded base plate 401 are integrally formed with limiting seats 403, and the four inner corners of the molded base plate 401 and the outer side of the limiting seats 403 are integrally formed with limiting posts 404; wherein the ribs 402 can increase the strength of the molded base plate 401, so that the two speaker boxes 3 are stably connected; the limiting seats 403 facilitate the installation and removal of the decorative panel 9, and the limiting posts 404 facilitate the installation of the support component 8.

[0028] Furthermore, the rear center of the molded base plate 401 is integrally formed with an installation part, and the bottom of the installation part is fixedly connected with a press-type self-closing latch 5. The rear center of the bottom wall of the installation groove 2 is fixedly connected with a self-closing locking groove 6 that cooperates with the press-type self-closing latch 5. The installation part is provided with a pressing block, which locks the press-type self-closing latch 5 with the self-closing locking groove 6, so that the speaker box 3 is locked and secured when it is reset. At the same time, the pressing block can make the speaker box 3 automatically flip out of the installation groove 2.

[0029] Furthermore, the connecting component 4 includes a connecting plate 7, with protruding plates 701 integrally formed at each of the four corners of the connecting plate 7. The outer side of the protruding plate 701 is provided with a slot 702 facing inward. The front top of the connecting plate 7 is integrally formed with a folded plate 703 perpendicularly arranged thereto. The support component 8 is engaged inside the slot 702. The connecting plate 7 is located above the formed base plate 401, and the support component 8 is located between the connecting plate 7 and the formed base plate 401 to support and resolve the sound transmission of the speaker cabinet 3 to the resonance of the large components. At the same time, the support component 8 can be movably engaged in the slot 702 for easy installation and disassembly.

[0030] Furthermore, a transition plate 704 is riveted to the front side of the folding plate 703. Connecting ear plates 705 are integrally formed on both the left and right sides of the upper end of the transition plate 704. The outer sides of the two connecting ear plates 705 are provided with the same connecting frame 706. Support plates are integrally formed at the bottom of both ends of the connecting frame 706. The support plates are bolted to the front end of the portable case 1. The connecting plate 7 is riveted to the folding plate 703 and the transition plate 704 to form a whole, so that the connecting plate 7 can be connected to the connecting frame 706. At the same time, the connecting frame 706 is bolted to the portable case 1, so that the speaker cabinet 3 is supported.

[0031] Furthermore, the connecting ear plate 705 has a round hole at the end away from the transition plate 704, and positioning pins 707 are fixedly installed at the middle of both ends of the connecting frame 706. The connecting ear plate 705 is sleeved on the outside of the positioning pin 707 through the round hole. A sleeve is sleeved on the outside of the end of the positioning pin 707 away from the connecting frame 706, and a set nut 708 is screwed on the end of the positioning pin 707 away from the connecting frame 706. A washer 709 is provided on the side of the set nut 708 near the sleeve, and an assist spring 710 is sleeved on the outside of the sleeve. In this way, the pressing block can separate the pressing self-closing latch 5 from the self-closing locking groove 6, so that the assist spring 710 loses its limit and resets. The assist spring 710 drives the transition plate 704, the folding plate 703 and the connecting plate 7 to flip through the connecting ear plate 705, so that the speaker cabinet 3 can automatically flip out of the mounting groove 2 and form a certain angle.

[0032] Furthermore, one end of the assist spring 710 is fixed to the connecting ear plate 705, and the other end of the assist spring 710 is fixed to the connecting frame 706. The two ends of the connecting frame 706 are fixedly connected to the limit pins 711 below the positioning pins 707. The upper end of the connecting ear plate 705 and the side near the limit pins 711 are provided with a limit groove. In this way, when the assist spring 710 loses its limit, it can automatically drive the speaker cabinet 3 to flip. When the inner wall of the limit groove on the connecting ear plate 705 contacts the limit pins 711, the connecting ear plate 705 is positioned, thereby positioning the flip angle of the speaker cabinet 3.

[0033] Furthermore, a decorative plate 9 is provided above the connecting plate 7. The rear end of the decorative plate 9 is provided with a clearance hole 901 that cooperates with the mounting part. The front end of the decorative plate 9 is integrally formed with a cover shell 902.

The bottom end of the connecting post 903 is fitted with a rubber plug 904. The bottom end of the rubber plug 904 is inserted into the inside of the limiting seat 403. The cover shell 902 covers the rear side of the folding plate 703 and the transition plate 704. The connecting post 903 and the rubber plug 904 are inserted into the limiting seat 403, so that the connecting plate 7 is stably limited between the decorative plate 9 and the molded base plate 401. Thus, the speaker box 3, the molded base plate 401, the connecting plate 7 and the decorative plate 9 form a whole. This whole is not only beautiful, but also allows for smooth rotation.

[0034] Furthermore, the support assembly 8 includes a cylindrical head 801, with an insertion hole 803 in the middle, an annular groove 802 on the outer side of the lower end of the cylindrical head 801, and an annular clearance groove on the lower surface of the cylindrical head 801 outside the insertion hole 803. Multiple spacer strips 804 arranged in an annular array are integrally formed inside the clearance groove. Multiple bosses 805 arranged in an annular array are integrally formed on the lower surface of the cylindrical head 801 between the clearance groove and the insertion hole 803. An annular mounting cavity is provided at the upper end of the cylindrical head 801 outside the insertion hole 803, and multiple spirally distributed partition plates are integrally formed inside the mounting cavity. The cylindrical head 801 is made entirely of silicone. The cylindrical head 801 is snapped into the slot 702 through the annular groove 802. The cylindrical head 801 is sleeved on the outside of the limiting post 404 through the insertion hole 803. The upper surface of the cylindrical head 801 contacts the lower surface of the decorative plate 9, and the lower surface of the boss 805 contacts the molded base plate 401. The cylindrical head 801 is made entirely of silicone, which will not damage the molded base plate 401 and the decorative plate 9. Moreover, the boss 805 contacts the molded base plate 401 in a point contact manner. With the help of the clearance groove, the spacer strip 804 and the spacer plate, the resonance problem between the sound of the speaker cabinet 3 and the large components is solved.
