Description
Technical field
The present invention relates to a kind of loop circuit voice coil motor.
Background technology
As mobile phone camera level turns into the important step of measurement mobile phone quality, each mobile phone brand is directed to the matter of camera
Amount requires also more and more higher.And voice coil motor is the heart of cell-phone camera in front, the quality of voice coil motor directly affects camera
Performance, and mobile phone be thinned trend under, mobile phone still must endure as various mechanical shocks；As shown in figure 1, conventional elastic piece
Formula voice coil motor include shell 1, upper cover plate 2, drive magnet 3, upper spring 4, circuit board 5, carry seat 6, induced magnet 7, coil 8,
Lower spring 9, the grade component of pedestal 10, its complicated and internal spring is easily deformed, so that camera appearance can not
The phenomenon of focusing.And spring-piece type voice coil motor is due to having a plurality of springs 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 cause focusing stabilization time time-consuming longer.
Because motor quality requirement is improved constantly, voice coil motor manufacturer proceeds by the research and development of no spring-piece type voice coil motor,
As Figure 2-3, in the prior art without spring-piece type voice coil motor include shell 11, 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, gripping in assembling and it is put into be compared and is stranded
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.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of loop circuit voice coil motor, it has
Effect solves problems of the prior art.
To achieve the above object, the present invention uses following technical scheme：
A kind of loop circuit voice coil motor, the loop circuit voice coil motor include shell, carry seat, yoke one, magnet, pedestal,
Yoke two, coil and circuit board；The guiding mechanism of the loop circuit voice coil motor include guide mechanism and with the guide mechanism
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 present invention has following advantageous effects：
The loop circuit voice coil motor of the application simplify 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；Structural improvement of the present invention roll structure probably due to dust and when causing to move interim card or it is stuck the problem of, the present invention
For slip friction mechanisms, dust less easily produces influence to this structure in motion.
