Further, having a gap between the second end and first end of the second yoke of the first yoke, magnet steel welded and installed is in this gap.
Further, the second end of the first yoke and the second yoke the first end at least one salient point and lower salient point are set, magnet steel is arranged between salient point and lower salient point.
Further, also including fixed structure, fixed structure passes through the welded and installed the second end at the first yoke and the first end of the second yoke.
Further, fixed structure is set to " U " type, and " U " type fixed structure is enclosed in the second end of the first yoke and the first end of the second yoke and magnet steel periphery, and the second end of the first yoke and the first end of the second yoke and magnet steel are adjacent to cladding.
Further, described fixed structure is stainless steel substrates.
Further, the second end of the first yoke and the first end of the second yoke are respectively provided with kink, and magnet steel is installed between this two kink.
After using such scheme, first end of this utility model the first yoke is arranged on coil block side and extends to coil block top, magnet steel connects the second end of the first yoke and the first end of the second yoke, second end opposing oscillatory of the second yoke installs armature, i.e. magnet steel is installed between the first yoke and the second yoke, thus realize the stable assembling of magnet steel and the first yoke and the second yoke, reduce the magnetic resistance of magnetic circuit, ensure the magnetic conduction efficiency of whole magnetic circuit system, avoid magnet steel problem of Cracking during producing assembling simultaneously.
