摘要： A piezo-electric resonant vibrator (206) comprises a resonant armature (2) including a plurality of planar spring members (22, 24, 26, 28) which are coupled centrally therewith and further detachably coupled to a perimetric rim (4). The planar spring members (22, 24, 26, 28) provide a restoring force normal to the movement of the armature (2). A weight (604) is centrally coupled to the armature (2). A housing (622, 624) encloses and supports the armature (2). A piezo-electric actuator (602) is coupled to the planar spring members (22, 24, 26, 28) for inducing movement of the armature (2) at a predetermined resonant frequency which is established when the rim (4) is detached from said planar spring members (22, 24, 26, 28).
