In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a combined NdFeB magnet for intelligent electroacoustics includes a magnet body 1, and the magnet body 1 includes a plurality of combination blocks 11. An insert block 12 is provided at one end of the combination block 11, and a slot 13 matched with the insert block 12 is provided at the other end. Adjacent combination blocks 11 can be connected by the cooperation of the insert block 12 and the slot 13, so that a plurality of combination blocks 11 can be connected into a magnet body 1. Therefore, when the magnet is large in volume and heavy in weight, the magnet can be installed by this means, which reduces the problem of inconvenient installation of the magnet body 1 or damage of the magnet plate during installation due to the large volume and heavy weight of the magnet, thereby facilitating the installation of the magnet body 1.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting groove 21 is provided at the end of the assembly block 11, and a limiting plate 22 is provided in the limiting groove 21 of the adjacent assembly blocks 11. After the assembly blocks 11 are assembled together, the limiting plate 22 is clamped in the limiting groove 21. The limiting plate 22 can play a certain limiting role between the adjacent assembly blocks 11, thereby improving the stability of the connection between the adjacent assembly blocks 11.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the end face of the limit plate 22 is provided with a plug post 23, and the combination block 11 is provided with a connecting groove 24 adapted to the plug post 23. When the limit plate 22 is set in the limit groove 21, the plug post 23 is inserted into the connecting groove 24, and the plug post 23 cooperates with the connecting groove 24, so that the limit plate 22 is not easy to fall off from the limit groove 21, thereby ensuring the stability of the setting of the limit plate 22, thereby ensuring the stability of the limit of the combination block 11.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a mounting seat 3 is provided at one end of the magnet body 1, a baffle 31 is provided at the upper end of the mounting seat 3, and a mounting piece 32 is provided at the end of the mounting seat 3 away from the baffle 31.

The mounting seat 3 is provided to facilitate the installation and connection of the magnet body 1. When the magnet body 1 needs to be installed and connected, the mounting piece 32 is first removed from the mounting seat 3, and the magnet body 1 is set at the upper end of the mounting seat 3 so that the end of the magnet body 1 is in conflict with the baffle 31, and then the mounting piece 32 is installed on the mounting seat 3 by using bolts. The mounting piece 32 cooperates with the baffle 31 to install the magnet body 1 on the mounting seat 3, and the magnet body 1 is located between the mounting piece 32 and the baffle 31, thereby ensuring the stability of the installation of the magnet body 1.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a cavity 33 is provided in the mounting seat 3, and a fan 34 is provided in the cavity 33 of the mounting seat 3. The fan 34 in the mounting seat 3 can ventilate and dissipate heat for the magnet body 1, thereby reducing the problem of poor heat dissipation of the magnet body 1 after long-term use, thereby extending the service life of the magnet body 1. The end faces of the mounting seat 3 are provided with heat dissipation strip holes 35, and the magnet body 1 is provided with a plurality of heat dissipation holes 4. By providing the heat dissipation strip holes 35 on the mounting seat 3 and the heat dissipation holes 4 on the magnet body 1, the heat dissipation effect of the magnet body 1 can be improved. When the equipment is operated for a long time, the magnet body 1 is still not prone to the problem of over-temperature, thereby further ensuring the service life of the magnet body 1.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a movable plate 5 is provided at the lower end of the mounting seat 3, and a placement groove 51 adapted to the movable plate 5 is opened in the mounting seat 3. The movable plate 5 is installed in the placement groove 51, which can play a certain sealing role on the cavity 33 of the mounting seat 3, and can reduce the problem of the fan 34 falling out of the cavity 33 of the mounting seat 3; a plug-in column 52 is provided at the end of the movable plate 5, and the mounting seat 3 is provided with a plug-in groove 53 connected with the placement groove 51 at the placement groove 51. When the movable plate 5 is placed in the placement groove 51, the plug-in column 52 is inserted into the plug-in groove 53 at the same time, and the plug-in column 52 cooperates with the plug-in groove 53, which can improve the tightness of the installation connection of the movable plate 5, so that the movable plate 5 is not easy to fall off from the mounting seat 3.
