摘要：
The motor includes a rigid anchormember which is fixedly mounted to theapplica-tor housing, an electromagnetic stator memberand an armature. The armature includes aperma-nent magnet assembly and two leaf springs whichconnect the anchor member and the armature, theleaf springs being positioned at right angles toeach other. The ratio of the lengths of the springmembers is within the range of 0.75:1 to 0.95:1.A driving assembly produces an alternatingcur-rent drive signal to the stator member whichmoves the armature and a skin contact memberat-tached thereto in a reciprocating motion whichin-cludes a first component perpendicular to theskin, a second component parallel to the skin anda third arcuate component.
