At this time, the sound effect of the speaker body 1 is not affected. After the connecting frame 302 is fitted with the installation frame 301, the elasticity of the tension spring 308 is used to make the pin 307 pass through the installation frame 301 and be inserted into the connecting frame 302, thereby fixing the filter 2 on the front side of the speaker body 1, avoiding the problem that when the speaker body 1 is not in use, the speaker on the front side thereof is attached with a lot of dust and affects the sound effect of the speaker body 1.

[0038] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0039] Specifically, by Figure 5 It is shown that the torsion spring 306 is sleeved on the outside of the rotating shaft 304 , and two ends of the torsion spring 306 are respectively connected to the inner wall of the rotating seat 303 and the outer wall of the rotating shaft 304 .

[0040] In the present invention, the torsion spring 306 is sleeved on the outside of the rotating shaft 304, and the two ends of the torsion spring 306 are respectively connected to the inner wall of the rotating seat 303 and the outer wall of the rotating shaft 304, thereby ensuring that the initial state of the torsion spring 306 keeps the filter 2 away from the speaker body 1.

[0041] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0042] Specifically, by Figure 8 It is shown that a pull ring 4 is installed on the outer wall of the pin 307, and anti-skid particles are integrally formed on the outer surface of the pull ring 4.

[0043] In the present invention, by providing the pull ring 4 with anti-skid particles, it is convenient for a person to pull the pin 307 manually and avoid the pin slipping out of the hand.

[0044] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0045] Specifically, by Figure 5 It is shown that a plurality of balls 5 are embedded in the inner wall of the rotating seat 303 , and an annular groove 6 matched with the balls 5 is formed on the outer wall of the rotating shaft 304 .

[0046] In the present invention, by providing the ball 5, the friction between the rotating seat 303 and the rotating shaft 304 is reduced, ensuring that the rotating shaft 304 rotates more smoothly.

[0047] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0048] Specifically, by Figure 2-Figure 4 It is shown that a round block 7 is installed on the rear side of the speaker body 1, a disc 8 is installed on the end of the round block 7 away from the speaker body 1, a positioning plate 9 is provided on the rear side of the speaker body 1, two shells 10 that are symmetrical to each other and matched with the disc 8 are installed on one side of the positioning plate 9, and a slot 11 matched with the round block 7 is opened on the front side of the shell 10.

[0049] In the present invention, after the round block 7 is inserted into the slot 11 , the housing 10 limits the disc 8 , thereby facilitating the hanging of the speaker body 1 on the positioning plate 9 , and facilitating the installation and removal of the speaker body 1 .

[0050] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0051] Specifically, by Figure 2It is shown that an adjusting bolt 12 is inserted into the front side of the positioning plate 9, an elastic gasket is provided between the adjusting bolt 12 and the positioning plate 9, and a threaded end of the adjusting bolt 12 is inserted into the elastic gasket.

[0052] In the utility model, by setting the adjusting bolt 12, the positioning plate 9 is conveniently fixed to the wall so that the speaker body 1 can be hung on the wall. By setting the elastic gasket, the pressure between the adjusting bolt 12 and the positioning plate 9 is reduced and the adjusting bolt 12 is prevented from loosening.

[0053] Furthermore, as a specific implementation of the present invention, the present invention provides a wall-mounted multimedia speaker.

[0054] Specifically, by Figure 1 , Figure 6 and Fig. 9 It is shown that a guide groove 13 is formed through the top of the installation frame 301, and a vertical rod 14 is slidably connected to the inner wall of the guide groove 13. A limit block 15 is installed on the top of the vertical rod 14, and a scraper rod 16 that fits with the rear side of the filter 2 is installed on the outer wall of the vertical rod 14.

[0055] In the present invention, the limit block 15 is provided to prevent the vertical rod 14 from being separated from the guide groove 13. The limit block 15 is moved to allow the vertical rod 14 to move in the guide groove 13, thereby facilitating the scraping of dust attached to the filter screen 2 after the filter screen 2 is opened.

[0056] Working principle:

[0057] The torsion spring 306 in the initial state drives the rotating shaft 304 in the rotating seat 303 to rotate, and uses the connecting block 305 to make the connecting frame 302 away from the front side of the speaker body 1. At this time, it does not affect the sound effect of the speaker body 1. After the connecting frame 302 is fitted with the installation frame 301, the elasticity of the tension spring 308 is used to make the pin 307 pass through the installation frame 301 and be inserted into the connecting frame 302, thereby fixing the filter 2 on the front side of the speaker body 1 to avoid the problem that when the speaker body 1 is not in use, the speaker on the front side is attached with a lot of dust and affects the sound effect of the speaker body 1.

[0058] After the round block 7 is inserted into the slot 11, the shell 10 limits the disc 8, which makes it convenient to hang the speaker body 1 on the positioning plate 9, and at the same time facilitates the installation and disassembly of the speaker body 1. By setting the limit block 15, the vertical rod 14 is prevented from being separated from the guide groove 13. The limit block 15 is moved to make the vertical rod 14 move in the guide groove 13, which makes it convenient to open the filter 2 and scrape off the dust attached to the filter 2.

[0059] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
