Can strengthen coil magnetic field's voice coil motor

The utility model discloses a can strengthen coil magnetic field's voice coil motor, it includes: the cooperation was in the same place about base, yoke board, support, coil and an at least magnet, base were with the yoke board, support, coil and magnet setting are in base and yoke board, the coil corresponds the device control support with magnet and operates from top to bottom, the bottom surface and a magnet vane of magnet are together fixed. The utility model discloses a set up in the bottom surface of magnet with the fixed magnet vane together of magnet, make magnet vane adsorb and play the effect that cuts off magnetic field on magnet, through magnet vane give " the fender goes back " with the magnetic field of magnet bottom effluvium thus humidification in the magnetic field of coillets the magnetism that passes the coil feel more crypto set of line promptly, intensity of overflow tank is bigger. The utility model discloses it can humidification in the magnetic field intensityof coil only to increase m
