A linear vibration motor comprising a housing, a vibrator, and a stator fixed on the housing and arranged parallel to the vibrator, push-pull magnets (4) are symmetrically disposed at two ends of the vibrator; push-pull coils (2) surrounding the push-pull magnets are fixedly disposed on the housing at positions corresponding to the push-pull magnets; after the push-pull coils are energized, the push-pull coils and the push-pull magnets generate push-pull forces in a horizontal direction, which provides a driving force for the reciprocating motion of the vibrator in a direction parallel to the plane in which the stator is located. The push-pull structure provides push-pull force for the reciprocation motion of the vibrator, so that an intense vibration force can be achieved.

A rotating machine is disclosed and includes a stator defining a circumference, a plurality of first magnet arrays, a rotor, and a first piston. The first magnet arrays are comprised of a plurality of discrete magnets arranged around the circumference of the stator in a first magnetic pattern. The rotor is rotatable about an axis of rotation and defines a main body. The main body defines a first passageway. The first piston includes a plurality of first magnetic elements and is actuated within the first passageway of the rotor. The plurality of discrete magnets are arranged in the first magnetic pattern and are positioned to interact with the magnetic elements of the first piston to create a first magnetic force as the rotor rotates about the axis of rotation. The first magnetic force represents a first amount of force required to actuate the first piston.
