When assembled, the horn wire 22 is led out from the first outlet 21, then passes through the sealing member 4 and the second outlet 32, and referring to fig. 2, the second outlet 32 can be sealed by the sealing plug 7. By arranging the outlet direction of the first outlet 21 and the outlet direction of the second outlet 32 to be non-parallel, the central axes of the first outlet 21 and the second outlet 32 are not collinear, so that the horn wire 22 left in the horn cavity 1 is not too tight or too short to be tensioned, and maintenance and disassembly are difficult. Because the outlet direction of the first outlet 21 and the outlet direction of the second outlet 32 have a certain angle, the horn wire 22 is not in a straightened state when the horn chamber 1 is disassembled, and the horn wire 22 with enough length is also arranged in the horn chamber 1, so that the disassembly is convenient.
