Specific embodiment
This utility model embodiment provides a kind of speaker module, improves the sealing of speaker such that it is able to expire
The performance requirement of sufficient speaker waterproof anti-gas-leak.
As Figure 1-4, this water-proof loudspeaker module includes vibrational system, magnetic circuit system and the fixing vibrational system of collecting
Aid system with magnetic circuit system；Vibrational system includes vibrating diaphragm；Aid system includes the first housing 1, the second housing 5；First shell
It is fixed with sealing gasket 4, sealing gasket 4 is closed annular, the first housing 1 or the second housing between the faying face of body 1 and the second housing 5
On 5 faying face, corresponding sealing gasket 4 position is provided with seal trim strip 2, by the extruding of sealing gasket 4 and seal trim strip 2, Ke Yiqi
To good sealing and waterproof effect.
In the present embodiment, the first housing 1 and the second housing 5 ultra-sonic welded, it is to avoid traditional gluing mode, this avoid
Increase thickness of shell, also strengthen the firmness that housing combines simultaneously.
The present embodiment, coordinates, by the way of setting sealing gasket 4 and seal trim strip 2, the resealing realizing housing, sealing
Pad 4 is molded, bonding or be embedded in module casing surface.The preferred sealing gasket of the present embodiment 4 is embedded on module casing faying face.
The present embodiment, sealing gasket 4 can reach the material of waterproof sealing effect using rubber ring, silicagel pad etc..
In above-described embodiment, sealing gasket 4 is provided with groove, and surface of shell is provided with corresponding with Baltimore groove has projective structure
Seal trim strip 2.
In above-described embodiment, in order to improve sealing structure service life it is preferred that sealing gasket 4 is to be fixed on the first housing 1
Surface or the second housing 5 surface silicagel pad.In the present embodiment, can adopt and sealing gasket 4 is fixed on the second housing 5 table
Face, seal trim strip 2 is fixed on the first housing 1 surface and corresponds to sealing gasket 4 position, and then the first housing 1 is ultrasonic with the second housing 5,
Realize the connection of shell, realize seal trim strip 2 and the extruding of sealing gasket 4.Connected and sealing gasket 4 and seal trim strip 2 using ultrasonic
Extruding realize the dual-seal of speaker module.
In the speaker that above-described embodiment provides, sealing gasket 4 and seal trim strip 2 are arranged at the inner side of ultrasonic point 3.This enforcement
Example, first with ultrasonic point 3 waterproof, after water enters ultrasonic point 3, using the extruding waterproof of sealing gasket 4 and seal trim strip 2, improves
