One end of the limit motor 302 is driven by a bidirectional threaded shaft 303. Both ends of the bidirectional threaded shaft 303 are threaded to one end of a limit plate 304. The other end of the limit plate 304 is penetrated by a limit screw 305. A protective plate 306 is hinged to one end of the limit plate 304.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a magnetic block is installed at the bottom of the mounting base 1. The driving pulley 102 and the driven pulley 104 are rotatably connected to the inside of the mounting base 1. The top of the driven pulley 104 is fixedly connected to the bottom of the turntable 2, and the turntable 2 is rotatably connected to the inside of the rotating groove 105.

[0027] In this embodiment, as Figure 1 , Figure 4 and Figure 5 As shown, the bidirectional threaded shaft 303 is rotatably connected to the inside of one side limit seat 301, and the limit screw 305 is installed inside the other side limit seat 301. Both ends of the limit plate 304 are equipped with sliders, and both sliders are slidably connected to the inside of the two limit seats 301.

[0028] In this embodiment, as Figure 4 As shown, there are two limiting plates 304 and two protective plates 306. Both the limiting plates 304 and the protective plates 306 are slidably connected to the top of the protective chamber 3. When one end of the two limiting plates 304 is in contact with each other, the two ends of the two protective plates 306 are respectively in contact with the top two ends of the protective chamber 3.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, when the sliders at both ends of the two limiting plates 304 slide to both ends of the limiting seat 301, the connection between the limiting plate 304 and the protective plate 306 is in contact with the top two ends of the protective chamber 3, and the limiting plate 304 and the protective plate 306 are perpendicular to each other, and the protective plate 306 is in contact with the outer walls of both ends of the protective chamber 3 respectively.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, the adjustment assembly 4 includes a fixing plate 401, which is installed at the center of the bottom inner wall of the protective chamber 3. Support seats 402 are installed on both sides of the top of the fixing plate 401. An adjustment motor 403 is installed on the top of one support seat 402.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, support frames 501 are installed on both sides of the bottom of the support plate 5, and the support frames 501 are all L-shaped structures. The bottom of one support frame 501 forms a threaded connection structure with the adjusting threaded shaft 404, and the bottom of the other support frame 501 forms a through connection structure with the adjusting screw 405. When the bottom of the support frame 501 and the bottom inner wall of the support frame 501 are in contact with each other, the top height of the loudspeaker body 6 is the same as the top height of the protective chamber 3.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this multi-directional advertising vehicle loudspeaker operates as follows:

[0033] First, use the magnetic block at the bottom of the mounting base 1 to magnetically fix it to the top of the vehicle to complete the installation of the vehicle loudspeaker. When needed, start the limit motor 302 at one end of the limit seat 301 on the top side of the protective compartment 3 to drive the bidirectional threaded shaft 303 inside the limit seat 301 to rotate, which will drive the sliders at one end of the two limit plates 304 to slide towards both ends of the protective compartment 3. At the same time, the sliders at the other end of the two limit plates 304 will slide synchronously under the action of the limit screw 305 inside the limit seat 301 on the other side.

[0034] Subsequently, when the limiting plate 304 slides to the top two ends of the protective chamber 3, the protective plate 306, which is hinged to one end of the limiting plate 304, rotates to a vertical state and fits against the outer walls of both ends of the protective chamber 3, thus opening the protective chamber 3.

[0035] Next, start the adjustment motor 403 on the top of the support base 402 at one end of the fixed plate 401 inside the protective chamber 3, drive the adjustment thread shaft 404 to rotate, drive the support frame 501 at one end of the support plate 5 to rise, and cooperate with the adjustment screw 405 in the other end of the support base 402 to drive the megaphone body 6 on the support plate 5 to rise to a suitable advertising height, and then start the megaphone body 6 to carry out the advertising operation.

[0036] Finally, the rotating motor 101 on the top of the mounting base 1 is started, driving the active pulley 102 to rotate. The transmission belt 103 drives the driven pulley 104 to rotate, which in turn drives the turntable 2 in the rotating groove 105 to rotate, thereby driving the megaphone body 6 in the protective chamber 3 on the turntable 2 to rotate, so as to carry out multi-directional rotating propaganda.
