Performance, and mobile phone slimming trend under, mobile phone still must endure as various mechanical shocks;As shown in figure 1, conventional elastic piece
Formula voice coil motor includes shell 1, upper cover plate 2, drive magnet 3, upper spring 4, circuit board 5, carries seat 6, induced magnet 7, coil 8,
Lower spring 9, the grade component of pedestal 10, its complicated and internal spring are easily deformed, so that camera appearance can not
The phenomenon of focusing.And spring-piece type voice coil motor is due to a plurality of springs being present inside motor, when user is intended to quickly be moved
When optical lens is focused, it is difficult to the problem of avoiding the simple harmonic motion of spring and then causing focusing stabilization time time-consuming longer.
Because motor quality requirement improves constantly, voice coil motor manufacturer proceeds by the research and development of no spring-piece type voice coil motor,
As Figure 2-3, include shell 11 without spring-piece type voice coil motor in the prior art, carry seat 12, ball 13, magnet 14, pedestal 15,
Yoke 16 and the grade component of coil 17, its guiding mechanism are the matched combined of a plurality of balls 13 and V-shaped groove 18, the quantity of ball 13
At least more than 6, due to only about 0.2 millimeter to 0.8 millimeter of ball diameter, the gripping in assembling is stranded with being put into comparison
Difficulty, and the material of ball is generally sintered ceramic material, cost is also costly.If in addition, have between ball and ball compared with
The dust of bulky grain is even stuck in the presence of the interim card for then easily causing motion.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of loop circuit voice coil motor,
It efficiently solves problems of the prior art.
To achieve the above object, the utility model uses following technical scheme:

The V-shaped groove being adapted;The guide mechanism is part cylindrical structure, and it is arranged on the load seat or the pedestal;The V
Shape groove is arranged on pedestal or carried on seat.
Further, the guide mechanism is the structure of a plastic injection, guide mechanism and the load seat or the pedestal one
It is body formed.
Further, single or a plurality of guiding mechanisms are provided with the loop circuit voice coil motor.
The utility model has following advantageous effects:
The loop circuit voice coil motor of the application it is simplified and optimize spring-piece type of the prior art with without spring-piece type voice coil loudspeaker voice coil horse
The structure reached, and then reduce material cost and assembly cost and lift motor assembly precision;Guide mechanism is with carrying seat or pedestal
Designer can be allowed in motor inherent space constraints system or when having particular design demand by being integrally formed, and the elasticity of Creative Design is simultaneously created
Benefit;When the utility model structural improvement roll structure may be because dust and cause to move interim card or it is stuck the problem of, this
Utility model is slip friction mechanisms, and dust less easily has an impact to this structure in motion.
