Specific embodiment
As shown in Figure 1, a kind of sebific duct exhaust rubber plug, including exhaust pition 1 and with 1 matched center of exhaust pition
Plug 2.
As shown in Fig. 2, exhaust pition 1 includes the first column structure 3 of ecto-entad setting, the second column structure 4 and the
Three column structures 5, the first column structure 3, the second column structure 4, third column structure 5 are cylinder, and the axis of three
It overlaps, the side that one end of the first column structure 3 is directed away from exhaust pition 1 is equipped with sealing lip 6, and sealing lip 6 is in loudspeaker
Shape, and horn-like larger one end is directed away from the side of exhaust pition 1, sealing lip 6 is so that the first column and sebific duct
Side wall better seal prevents the excessive of glue.
As shown in Figures 3 and 4, one end of the first column structure 3 connection sealing lip 6 is connected by the first seal face 12
