Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this
Utility model proposes a kind of embodiment of earphone, includes front housing 1, rear shell 2 and loudspeaker 3, before described referring to Fig.1 shown in-Fig. 3
Shell 1 be located in the rear shell 2 and be fixedly connected between the rear shell 2 through dispensing, specifically when cooperation, set in rear shell 2
It is equipped with the hollow card convex 21 being circumferentially arranged along rear shell 2, card convex 21 is the annular protrusion cylinder being connected to 2 inner space of rear shell,
The ladder bayonet 11 that the circumferential direction cooperated with card convex 21 is provided on 1 open end end face of front housing, ladder bayonet 11 are provided on front housing 1
It is connected to the space inside front housing 1, ladder bayonet 11 includes bottom surface 111 and side 112, it is preferred that before in the present embodiment
Shell 1 is a spherical shell, and in assembly, rear shell 2 is inserted into the ladder bayonet 11 of the front housing 1 by the card convex 21 and is realized
Front housing 1 is tentatively connected and fixed with rear shell 2, then corner's circumferential direction dispensing at 11 cooperation position of card convex 21 and ladder bayonet
Rear shell 2 and front housing 1 is fixed.
The loudspeaker 3 are located in the cavity that the front housing 1 and rear shell 2 are formed, for prevent glue from front housing 1 and rear shell 2 it
Between dispensing at cavity internally or the hull outside excessive glue formed to rear shell 2 and front housing 1, the front housing 1 with it is described after
It is provided between shell 2 for preventing glue from overflowing or interior excessive sealing structure.
A kind of preferred embodiment as sealing structure in the present embodiment is：The sealing structure includes first close
Sealing 4 and second seal 5, the first seal 4 and second seal 5 are respectively positioned on matching between the front housing 1 and rear shell 2
The coincidence place of setting and the two sides being separately positioned at the front housing 1 and the 2 dispensing position of rear shell.By first seal 4 and second
Sealing element 5 is correspondingly arranged between the rear shell 2 of two sides at dispensing position and front housing 1, and glue at dispensing position can be prevented to two
Side flowing is overflowed, and then is flowed into cavity or hull outside, has been effectively blocked the circulation passage of glue, has been formed to dispensing position
Set the sealing of place's glue.Sealing structure in through this embodiment is effectively avoided because glue flows into internal cavity
