Into.The monomer container 110 for fixing loudspeaker monomer is provided with bottom wall 11.Side wall 12 is around the monomer container 110
Set.
Specifically in the present embodiment, loudspeaker monomer is magnetic speaker, specifically includes vibrating diaphragm and the sound of driving vibration
Circle, the vibrating diaphragm of loudspeaker monomer can form the operatic tunes of loudspeaker module between bottom wall.Certainly, loudspeaker monomer can also be it
The microphone device of his species, its principle are identical.
It is further provided with going out part 13 to protruding outside away from receiving space on housing 1, goes out on part 13 and set
There is at least one passage 130 of speaking being connected with the operatic tunes.In present embodiment, go out part 13 and be located on side wall 12, be from side
For wall 12 to the cyclic structure of the formation protruding outside away from receiving space, going out part 13 includes the face of speaking along 12 direction of side wall
131 and the extended surface 132 that is connected with the face of speaking 131, wherein passage 130 of speaking is through face 131 of speaking.Specifically in this embodiment party
In formula, passage 130 of speaking has two, and scene 2 is spoken the retaining wall 134 being provided between passage for interval.Certainly, may be selected
Other embodiment in, it is possibility to have more than two passages 130 of speaking, and be correspondingly arranged multiple retaining walls 134, adjacent two
One retaining wall 134 is set between a passage 130 of speaking, and can implement, or a passage 130 of speaking only is set, no
Retaining wall 134 is set, and the utility model aim can be reached.
Loudspeaker module further includes the sealing shroud 2 around passage 130 of speaking.Sealing shroud 2 include cricoid main part 201 and
The bending extension of main body 201 is used for the fixed part 202 being fixedly connected with extended surface 132, and main part 201 is spoken equipped with connection
Passage 130 goes out acoustic aperture 20.Sealing shroud is used for realization sealing or the dustproof and waterproof of product, specifically in the present embodiment, sealing
Cover for silica gel sheath.The circumferential profile for going out part 13 is racetrack structure, and extended surface 132 includes a pair of of first surface 1321, a pair
Second surface 1322 and the transition face 1323 of the adjacent first surface 1321 of connection and second surface 1322, wherein first surface
1321 be to be set along bottom wall direction, and second surface 1322 is along perpendicular to the direction of bottom wall 11.It is corresponding, the fixed part of sealing shroud 2
202 be also cricoid racetrack structure.It is provided with first surface 1321 and prolongs along going out both sides above and below part perpendicular to bottom wall direction
The positioning column 133 to be formed is stretched, it is corresponding, the location hole 21 to match with positioning column 133,2 sets of sealing shroud are provided with sealing shroud 2
After entering out part 13, positioning column 133 is inserted in the positioning and fixation that sealing shroud 2 is realized in location hole 21.Specifically in present embodiment
In, positioning column 133 shares four, in pairs respectively on two first surfaces 1321.Certainly, in other selectable implementations
