[0005] Furthermore, the sound-generating structure includes an iron core fixed to the shell, and an electromagnetic coil is sleeved on the iron core; a vibration sheet corresponding to the electromagnetic coil is arranged in the shell, and a magnet corresponding to the vibration sheet is arranged on the cover plate.

[0006] Furthermore, a stabilizing tube corresponding to the shell is fixedly connected to the cover plate, and one end of the loudspeaker tube away from the supporting plate is fixedly connected to the stabilizing tube.

[0007] Furthermore, an upper dustproof net corresponding to the upper sound-emitting hole is fixedly connected to the inner wall of the stabilizing tube, and a side dustproof net corresponding to the side sound-emitting hole is also fixedly connected to the stabilizing tube.

[0008] Furthermore, lower stabilizing columns are evenly distributed on the support ring, and lower stabilizing holes corresponding to the lower stabilizing columns are provided on the support plate.

[0009] Furthermore, an upper stabilizing column corresponding to the lower stabilizing column is fixedly connected to the shell, and an upper stabilizing hole corresponding to the upper stabilizing column is provided on the cover 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, through the arrangement of the upper sound hole, the side sound hole, the loudspeaker, the sound amplifying board, etc., the sound-emitting structure emits a sound, which is amplified by the loudspeaker and the sound amplifying board and then emitted from the upper sound hole and the side sound hole, thereby realizing multi-angle sound emission of the buzzer and improving the sound emission effect of the present application.
