Chamfered of one end of 111, injecting glue groove 181 is opened on this fillet surface.Similarly, the second barricade
132, third gear wall 133 and fourth gear wall 134 also can be correspondingly arranged into the structure with fillet surface.
When the Tibetan glue groove 15 in described first gluing blind area 40 and described second gluing blind area 50 is carried out
During glue operation, leading glue groove 16 and described second described first and lead in glue groove 17, described glue is noted
Enter described injecting glue groove 181, then pass through described in lead glue slope 183 and flow to described first gluing blind area 40
Tibetan glue groove 15 in, described air discharge duct 185 is discharged gas thus is promoted that described glue is at described first dozen
Flowing in glue blind area 40；Leading in glue groove 17 described second, described glue injects described injecting glue groove
181, then pass through described in lead glue slope 183 and flow to the Tibetan glue groove 15 of described second gluing blind area 50
In, described air discharge duct 185 is discharged gas thus is promoted that described glue is in described second gluing blind area 50
Interior flowing.
And, lead glue groove 16 and described second described first and lead in glue groove 17, if described in lead glue
The gradient on slope 183 is too steep, may result in the flowing of described glue too fast and at the described Tibetan glue being blocked
Do not plan a successor in groove 15 phenomenon, if described in lead the gradient on glue slope 183 peaceful, may result in described
The Tibetan glue groove 15 being blocked slowly cannot be filled up by glue flowing.Therefore, in order to ensure described glue
Can flow gently thus the described Tibetan glue groove 15 being blocked is filled up, described in lead the oblique of glue slope 183
The squint angle of domatic relative Tibetan glue groove 15 is set between 25-35 °.And, in order to described glue
Reserved packing space, the reserved 0.15mm's between described Tibetan glue groove 15 and described sounding monomer 20
Gap.
Further, in order to ensure the positioning precision of described sounding monomer 20, described first barricade 131
Described first lead glue groove 16 and described second lead be additionally provided with between glue groove 17 location rib 19, institute
State location rib 19 and be perpendicular to the straight wall of described base plate 111, and by abutting described sounding monomer
The frame 21 of 20 and position described sounding monomer 20.
Certainly, being not limited to the present embodiment, in other alternate embodiments, described circuit board 30 is permissible
Limiting section 13 described in partial occlusion and the Tibetan glue groove 15 between described sounding monomer 20 and form an institute
State gluing blind area described in gluing blind area or at least three.Accordingly, described limiting section 13 can be formed
Have described in one to lead and described in glue groove or at least three, lead glue groove, and corresponding one of each described gluing blind area
Described lead glue groove.
In the speaker 100 that this utility model provides, the limiting section 13 of described pedestal 11 houses described
Sounding monomer 20, described circuit board 30 is weldingly fixed on described sounding monomer 20, and partial occlusion
Tibetan glue groove 15 between described limiting section 13 and described sounding monomer 20 and to form described first gluing blind
District 40 and described second gluing blind area 50；And the first barricade 131 of described limiting section be formed right
The first of described first gluing blind area 40 setting is answered to lead glue groove 16 and the described second gluing blind area 50 of correspondence
Second arranged leads glue groove 17, and described first leads glue groove 16 and described second leads glue groove 17 and guide respectively
Glue flow in the Tibetan glue groove 15 in described first gluing blind area 40 and described second gluing blind area 50.
Therefore, described speaker 100 can be led glue groove 16 and described second by described first and be led glue groove
17 carry out glue operation respectively in described first gluing blind area 40 and described second gluing blind area 50,
Thus improve seal and the reliability of described speaker 100, and then improve described speaker 100
Service behaviour.
Above-described is only embodiment of the present utility model, it should be noted here that for this area
Those of ordinary skill for, without departing from this utility model create design on the premise of, it is also possible to do
Go out to improve, but these belong to protection domain of the present utility model.
