The working principle and advantage of the utility model are as follows：
A kind of newly-designed voice coil motor shell of the utility model, including yoke and lower cover；Yoke by rectangular-shaped top plate and
Four side plates composition；Rectangular-shaped top plate portion offers first through hole, and four side plates are integrally extended to along its four edges respectively by rectangular-shaped top plate
Under be bent to form；The lower part that lower cover is assemblied in yoke is open, including flat lid, offers second in the middle part of flat lid
Through-hole is coaxially disposed with first through hole；The surrounding of lower cap upper surface is recessed, and forms rectangular ring locating slot, yoke is with its four side
The bottom of plate is inserted into cyclic annular locating slot, and the inside of each side plate is bonded the cell wall of cyclic annular locating slot, and each side plate is positioned with cyclic annular
The binding site of slot is connected by viscose.
Compared to existing technologies, the sealing mode of the utility model is changed to internal sealing, there is an advantage in that：1,
Viscose area when can effectively increase module group assembling increases mould group and pushes and pulls pull out force, increase Client Enterprise production yield, meets visitor
Family enterprise pushes and pulls pull out force demand；2, the production procedure that can simplify voice coil motor, the direct dispensing before yoke, lower cover assemble, no
Secondary turn over is carried out with because of finished product sealing；3, it not will cause the bad orders such as the bottom excessive glue of voice coil motor in process of production to ask
Topic.
