Passed through in the U-lag of shell；Yoke is additionally provided with the U-type groove of the U magnet shell, two positioned at the armature bottom
Side；Magnet is also welded with one end of the U magnet shell and the armature lower weld, closes the U magnet shell
Opening.
Preferably, the top of the armature is sheet, and bottom is strip or sheet.
Preferably, the bottom of the armature is completely covered in the top of the armature.
Preferably, the yoke stacks setting successively by multiple square ring sheet materials, and uppermost 2 ~ 4 ring-type sheet materials are not
Closure, leaving certain gaps uncovered by the economic plan；Ring-type sheet material periphery in an intermediate position is provided with locating piece.
Preferably, the dynamic iron unit also includes drive device, and the armature bottom is shaken by drive device connection
Film.
Dynamic iron unit coil provided by the invention is fixed in coil plate, prevents rocking for coil from coming off, to coil electricity,
Armature is changing to magnet, and one end of armature and magnet shell are welded and fixed.Also one end is stretched out among magnet shell, is powered
Under state, yoke and armature just has antipodal magnetic pole inside yoke.With welding inside the big face of magnet shell
Mode fixed magnet, one end of armature and magnet shell are fixed, and weld magnet on the face that armature and magnet shell are fixed, armature by
To the power of coil current, obstructed magnetic force is produced, in the vibrations that magnet enclosure occurs, armature is fixedly arranged at the front end with drive division
Part, driving part connection occur film, finally send sound.U magnet shell is added, the armature bottom is filled using magnet
Space in U magnet shell is seamless, and magnetic field will not disappear, and improves the accuracy rate of sound.Or it is used in combination using yoke
Magnet seal, so do and supplemented with magnet because magnetic field caused by gap disappears, improve the accuracy rate of sound.
