Abstract: Disclosed are a motor (20, 40, 50, 60, 70, 80), a camera module (100), and a mobile terminal (200). A motor (20, 40, 50, 60, 70, 80) includes a base (21, 41, 51, 61, 71, 81), a support base (23, 43, 53, 63, 73, 83), and a shape memory alloy actuator (25). The shape memory alloy actuator (25) is fixedly connected between the base (21, 41, 51, 61, 71, 81) and the support base (23, 43, 53, 63, 73, 83), and the shape memory alloy actuator (25) is configured to drive the support base (23, 43, 53, 63, 73, 83) to move relative to the base (21, 41, 51, 61, 71, 81). The motor (20) further includes an eccentricity-prevention magnetic assembly (27, 47, 57), the eccentricity-prevention magnetic assembly (27, 47, 57) includes a first eccentricity-prevention member (271, 471, 571, 771, 871) and a second eccentricity-prevention member (273, 473, 573, 773, 873), the first eccentricity-prevention member (271, 471, 571, 771, 871) is disposed on the base (21, 41, 51, 61, 71, 81), the second eccentricity-prevention member (273, 473, 573, 773, 873) is disposed on the support base (23, 43, 53, 63, 73, 83), and when the motor is in a powered-off state, a first central axis of the base (21, 41, 51, 61, 71, 81) coincides with a second central axis of the support base (23, 43, 53, 63, 73, 83) under the action of magnetostatic forces between the first eccentricity-prevention member (271, 471, 571, 771, 871) and the second eccentricity-prevention member (273, 473, 573, 773, 873), to resolve the problem of eccentricity of the motor (20, 40, 50, 60, 70, 80).

Abstract: An elastomer includes an elastomer body and at least one elastomer cantilever. The elastomer cantilever is coupled to the elastomer body and extends along an outer edge of the elastomer body, the at least one elastomer cantilever is coupled to the fastener at a predetermined position of an extending part, and the at least one elastomer cantilever is axisymmetric or 90° rotationally symmetric.
