[0007] Through the above technical solution, when the speaker is outdoors without rain, the fixed bar and the movable bar are brought together to fold the foldable waterproof cloth together, thereby increasing the open-air area of ​​the waterproof cover and facilitating the speaker to transmit sound. When it rains outdoors, the movable bar is allowed to slide inside the limit groove, and the foldable waterproof cloth between the fixed bar and the movable bar is stretched out to cover the waterproof cover to prevent the MEMS speaker body from contacting rainwater, thereby achieving a shielding and waterproofing effect, thereby ensuring that the speaker can work normally and the sound quality will not be degraded due to water immersion.

[0008] Furthermore, a motor is fixedly mounted on the top plate of the waterproof cover, a rotating rod is arranged above the waterproof cover, the rotating rod is fixedly connected to the output end of the motor, and the rotating rod is fixed to the moving bar through a connecting block.

[0009] Through the above technical solution, the starting motor drives the rotating rod to rotate, and the rotating rod drives the moving bar to slide back and forth along the limiting groove through the connecting block, thereby realizing the automation of opening and closing of the waterproof unit.

[0010] Furthermore, a movable groove is provided on one side of the upper limit groove on the outer surface of the waterproof cover, and the connecting block matches the movable groove.

[0011] Through the above technical solution, the connecting block can move along a specified track by setting the moving groove.

[0012] Furthermore, a mounting seat is fixedly installed on one side of the fixing seat inside the waterproof cover, the MEMS speaker body is rotatably connected to the inside of the mounting seat, and a knob for controlling the rotation of the MEMS speaker body is provided on one side of the mounting seat.

[0013] Through the above technical solution, the MEMS speaker body is driven to rotate by rotating the knob, thereby facilitating the adjustment of the angle of the MEMS speaker body.
