Description
Technical field
This utility model relates to micro machine field, particularly relates to metal reinforcement plate and the voice coil loudspeaker voice coil horse of a kind of voice coil motor
Reach.
Background technology
The production method of traditional voice coil motor, the position limiting structure of motor down stroke typically by working of plastics and working of plastics or
Person's working of plastics and metalwork composition, i.e. carrier form the spacing knot of voice coil motor down stroke with base or lower shell fragment with base
Structure.During motor downward movement, the frictional impact between working of plastics and working of plastics or between working of plastics and metalwork,
Working of plastics can be made to produce chip, and chip drops, and makes camera module produce fouling problems, causes camera module bad.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides the metal reinforcement of a kind of voice coil motor
Plate, this metal reinforcement plate can solve the problem that the carrier of voice coil motor when down stroke, lower shell fragment and base frictional impact produce chip,
And then camera module is caused dirty problem, it is possible to increase voice coil motor and the yields of camera module.
This utility model additionally provides a kind of voice coil motor employing above-mentioned metal reinforcement plate, and this voice coil motor will not be sent out
The raw plastic scrap that in use produces, and then pollute the situation of camera module.
Technical problem to be solved in the utility model is achieved by the following technical programs:
The metal reinforcement plate of a kind of voice coil motor, described metal reinforcement plate is provided with PIN and some bulge-structures.
A kind of voice coil motor, including base and the carrier being arranged on described base, the outside of described carrier is provided with coil,
The outside of described coil is provided with magnet assembly, and described base is provided with above-mentioned metal reinforcement plate, institute towards the side of described carrier
State carrier and be provided with lower shell fragment towards the side of described base.
Further, described carrier is provided with shell fragment.
Further, described upper shell fragment is provided with shell fragment lid.
Further, described magnet assembly is four pieces of permanent magnets.
Further, the outside of described magnet assembly is additionally provided with yoke.
This utility model has the advantages that this metal reinforcement plate is arranged on the base of voice coil motor, and they are some
Described carrier can be played spacing and buffering when the carrier down stroke of voice coil motor together with described lower shell fragment by bulge-structure
Effect, and the frictional impact between metal and metal will not produce chip, does not results in the fouling problems of camera module, makes
Voice coil motor with this metal reinforcement plate is functional, it is possible to increase voice coil motor and the yields of camera module.
Accompanying drawing explanation
The top view of the metal reinforcement plate of the voice coil motor that Fig. 1 provides for this utility model；
Fig. 2 is the A-A profile of the voice coil motor shown in Fig. 1；
The exploded view of the voice coil motor that Fig. 3 provides for this utility model.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
As illustrated in fig. 1 and 2, the metal reinforcement plate 5 of a kind of voice coil motor, described metal reinforcement plate 5 is provided with PIN 52
With some bulge-structures 51.
Embodiment 2
As it is shown on figure 3, a kind of voice coil motor, including base 1 and the carrier 2 being arranged on described base 1, described carrier 2
Outside be provided with coil 3, the outside of described coil 3 is provided with magnet assembly 4, and described base 1 is provided with towards the side of described carrier 2
Metal reinforcement plate 5 described in embodiment 1, described carrier 2 is provided with lower shell fragment 6 towards the side of described base 1.
This metal reinforcement plate 5 is arranged on the base 1 of voice coil motor, and its some bulge-structures 51 can be at described carrier 2
Down stroke time, to described carrier 2 to effect that is spacing and that buffer together with lower shell fragment 6, and rubbing between metal and metal
Sidewipe collision will not produce chip, does not results in the fouling problems of camera module, employs the voice coil motor of this metal reinforcement plate 5
Can be good, it is possible to increase voice coil motor and the yields of camera module.
Described carrier 2 is provided above with shell fragment 7, and described upper shell fragment 7 is provided with shell fragment lid (not shown), institute
State shell fragment 7 and upper shell fragment lid (not shown) for when described carrier 2 up stroke, play the spacing and effect of buffering.
PIN 52 on described metal reinforcement plate 5, through described base 1, is used for connecting power supply.
Described magnet assembly 4 is four pieces of permanent magnets, lays respectively at outside described coil 3 and mutually forms a square arrangement.
The outside of described magnet assembly 4 is additionally provided with yoke 8, and described yoke 8 is for the magnetic force concentrating magnet assembly 4 to produce
Line, and the parts of voice coil motor are played protection, fixation.
Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but also
Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as using equivalent or the form institute of equivalent transformation
The technical scheme obtained, all should fall within protection domain of the present utility model.
