Described lower casing assembly 1 includes lower casing 101, FPC102 and coil 103, and FPC102 is arranged on bottom lower casing 101, institute
State coil 103 to be arranged at lower casing 101 bottom centre；Described mover assembly 2 includes oscillator 201, is arranged on oscillator 201
In flux sleeve 202, the magnet steel 203 being arranged in flux sleeve 202, the magnetic conduction sheet 204 being arranged on magnet steel 203 and be sleeved on
The spring 205 fixed on flux sleeve 202 and with oscillator 201；Described spring 205 is disc-shaped, the excircle of spring 205
Being provided with several locating pieces 2051, described spring 205 center offers magnetic conduction trepanning 2052, described spring 205 also sets
Several arc-shaped slots 2053, described arc-shaped slot 2053 is had to be arranged between magnetic conduction trepanning 2052 and excircle and around flux sleeve
Hole 2052 rotates to be arranged；The lateral surface of each described locating piece 2051 is arc surface and each arc surface is concentric with magnetic conduction trepanning 2052.
Concrete, interference fit between oscillator 201 in mover assembly 2 and flux sleeve 202, between magnet steel 203 and flux sleeve 202,
