The utility model discloses an improved convolution oscillator which comprises a shell consisting of a surface shell and a base plate, wherein a motor, a speed reduction transmission device, an eccentric shaft, a lower convolution bracket and an upper convolution bracket are arranged in the shell; through the speed reduction transmission device, the motor is connected with the eccentric shaft for driving the lower convolution bracket and the upper convolution bracket to do convolution oscillation motion; the lower convolution bracket is connected with a support in the shell through a first group of damping steel sheets; the lower convolution bracket is connected with the upper convolution bracket through a second group of damping steel sheets. According to the improved convolution oscillator, the single eccentric shaft is adopted to drive the lower convolution bracket and the upper convolution bracket to do the convolution oscillation motion; furthermore, tension generated by the two groups of the damping steel sheets can counteract resistance caused by eccentric motion rotation, so that planar convolution of the convolution brackets cannot generate component force in the horizontal direction. The improved convolution oscillator has the advantages of continuity and stability in motion, large convolution torque, high rigidity and low noise.
