[0008] Furthermore, the shell is provided with a collecting groove matched with the heat dissipation hole, and the bottom of the shell is evenly distributed with drainage holes connected with the collecting groove.
[0009] Furthermore, an upper water baffle plate which cooperates with the second sound-emitting hole on the outer ring is fixedly connected to the top plate.
[0010] Furthermore, a pair of fixing legs is provided at one end of the shell away from the cover plate, and mounting holes are provided on each of the pair of fixing legs.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] When the utility model is in use, the direction of the first sound hole on the top cover is changed by setting the second sound hole on the inner ring and the outer ring, and the second sound hole is waterproofed by the cooperation of the first annular plate and the second annular plate, which can effectively prevent rainwater from entering the shell through the second sound hole and the first sound hole, thereby improving the stability of the application.
