Rectilinear oscillation driver

The utility model discloses a linear oscillation driver, which has minimum incidental oscillation or stress and can move smoothly and reciprocally. The driver comprises an oscillator, an output shaft and a stator assembly provided with an electromagnet, wherein the output shaft is provided with a permanent magnet and is suitable to be connected to drive loads, and the electromagnet produces a magnetic field. The magnetic field interacts with the permanent magnet, therefore the oscillator can move reciprocally on a linear path correspondingly to the stator assembly. A spring connecting rod is arranged to elastically support the oscillator on the stator assembly, a gap distance is arranged between the oscillator and the stator assembly, therefore the oscillator is allowed to move reciprocally along the linear path. The spring connecting rod is arranged to elastically deform on different linear paths, therefore the oscillator is allowed to move toward and away from the stator assembly or twist correspondingly to the stator assembly.
