Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As depicted in figs. 1 and 2, a kind of megaphone sealing structure of the utility model, including rear cover 1, wiring board 2, loudspeaker
Shell 3, end cap 4, button 5 and rubber tarpaulin 6；The rear cover 1 is fixed with 3 sealing screw of loudspeaker shell；The button 5
One end and the end cap 4 cooperate, and the other end is contacted with several 6 end faces of rubber tarpaulin；Several rubber tarpaulins 6 are close
Envelope is bonded installation with the rear cover 1；The end cap 4, which connects and fixes, is mounted on 1 side of rear cover, the rear cover 1 it is another
Side is coupled with the wiring board 2；Through-hole 8 and the rubber of several switches 7 across the rear cover 1 on the wiring board 2
The contact of 6 end face of skin tarpaulin.
As shown in figure 3, the side of the rear cover 1 is provided with the groove 9 cooperated with several rubber tarpaulins 6, this is recessed
Slot 9 is convenient for cooperating with rubber tarpaulin 6, is convenient for the quick location and installation of rubber tarpaulin 6.
As shown in figure 4, the cross sectional shape of the rubber tarpaulin 6 is concave, convenient for cooperating with groove 9.
As shown in Fig. 2, the megaphone sealing structure further includes live wire sealing device, the wire seal device includes
Electric wire 10, nut 11, rubber seal plug 12 and fixing seat 13；The fixing seat 13, which connects and fixes, is mounted on 1 lower end of rear cover
Side；The nut 11 screws fixation with 13 internal and external threads of fixing seat；The rubber seal plug 12 is arranged in the fixation
In the cavity 14 of seat 13；The electric wire 10 passes through the nut 11, rubber seal plug 12 and fixing seat 13 and is connected into the rear cover 1
