Abstract
The utility model discloses a flat elastic piece for a voice coil motor. The flat elastic piece is used for the voice coil motor, and comprises a hollow fixing frame having a shape of a rectangular frame, a connecting piece and an elastic piece, wherein the elastic piece has an annular structure, and is connected to an inner part of the fixing frame through the connecting piece. The flat elastic piece for the voice coil motor has high actuating performance and high stability.
Description
Technical field
The utility model relates to miniature actuating device field, relates more specifically to a kind of voice coil motor that is applied on the voice coil motor and uses flat elastic piece.
Background technology
Along with the high speed development of portable consumption electronic products technology such as mobile phone, digital camera, the popularity of consumer electronics is increasingly high.People also have increasingly high pursuit to portable type electronic product when enjoying modern scientific and technical result, hope that portable electronic product can effectively reduce volume.But be subject to the development of dynamo-electric whole system; And micro electronmechanical (Microelectromechanical Systems; MEMS) application universalness not as yet is so (Voice Coil Motor VCM) is actuating system on the electronic product to industry widespread usage voice coil motor.
Voice coil motor (VCM) has advantages such as volume is little, and power consumption is few, the actuating displacement is accurate and cheap.Be suitable as the short distance brake in the electronic product, like the upper and lower displacement actuator on mobile phone vibrating motor magnetic head/optical read/write head, the automatic focus actuator of camera or the like.Yet, the actuating of voice coil motor/recovery pace of change compared to electronic product easily several milliseconds pace of change be slower a bit, therefore, in the middle of voice coil motor, can add at least a shell fragment and quicken the pace of change that activates/restore.Usually, voice coil motor comprises that a sidewall is the square fixation kit with magnetic, and one is provided with voice coil loudspeaker voice coil and is contained in the movable part in this square fixation kit.Behind the logical upward electric current of this coil, the Lorentz force that this coil groups produces in this magnetic part acting in conjunction makes this movable part move along the central axis direction of this square fixation kit, thereby realizes that short distance moves.
After voice coil motor assembles, become business men need pass through Dan Pin and fall and the bale packaging drop test, the voice coil motor of test passes just can come into the market.In the process of test, because the microminiaturization of voice coil motor, cause when assembling shell fragment to be difficult for assembling and easy deformation extremely.Therefore when drop test, the adhesion deficiency of normal because shell fragment and support causes shell fragment to come off, so the actuating performance that causes this voice coil motor with and less stable.
In actual use, shell fragment produces elastic deformation when work, and the stress that the junction of shell fragment and fixed frame receives is maximum, to such an extent as to surpass elastically-deformable scope, thus cause shell fragment to follow the string.
Therefore need badly and a kind ofly activate performance and the good voice coil motor of stability is used flat elastic piece.
The utility model content
The purpose of the utility model provides and a kind ofly activates performance and the good voice coil motor of stability is used flat elastic piece.
