Disclosed by the present invention are a swing motor and an electronic device, the swing motor comprising a seat; at least two movable members, comprising a first movable member and a second movable member arranged to be spaced apart, wherein the first movable member and the second movable member bear opposite electromagnetic thrusts; elastic support members that correspond one-to-one to the movable members, comprising a first elastic support member and a second elastic support member, wherein the first movable member is mounted onto the seat by means of the first elastic support member, and the second movable member is mounted onto the seat by means of the second elastic support member; further comprised is a twisting elastic member, one end of the twisting elastic member being connected to the first movable member or the second movable member, and the other end being connected to an executing member. The swing motor according to the present invention may use the twisting elastic member to reduce the transfer of rotational torque to the seat without increasing falling blocks, thereby miniaturizing the motor; the electric device may reduce vibration and may lighten the weight.La présente invention concerne un moteur oscillant et un dispositif électronique, le moteur oscillant comprenant : un siège ; au moins deux éléments mobiles, comprenant un premier élément mobile et un second élément mobile agencés de sorte à être espacés, le premier élément mobile et le second élément mobile supportant des poussées électromagnétiques opposées ; des éléments de support élastiques qui correspondent un à un aux éléments mobiles, comprenant un premier élément de support élastique et un second élément de support élastique, le premier élément mobile étant monté sur le siège au moyen du premier élément de support élastique, et le second élément mobile étant monté sur le siège au moyen du second élément de support élastique. Ledit moteur comprend en outre un élément élastique de torsio
