The invention discloses a linear vibrator, a swinging device, a baby crib and a control method of the linear vibrator, and relates to the technical field of vibration, and the linear vibrator comprises an eccentric wheel set and a driving device. The eccentric wheel set comprises a first eccentric wheel and a second eccentric wheel with the same mass. The driving device is used for driving the first eccentric wheel and the second eccentric wheel to rotate reversely at the same speed, the rotating axis of the first eccentric wheel is a first axis, the rotating axis of the second eccentric wheel is a second axis, and the first axis and the second axis are parallel or coincide. The distance between the first mass center of the first eccentric wheel and the first axis is equal to the distance between the second mass center of the second eccentric wheel and the second axis. The eccentric wheel set is driven by the driving device to achieve linear vibration, the linear vibration motor is simple in structure and low in cost, and compared with a traditional linear vibration motor, the driving efficiency is higher, and vibration with lower frequency can be generated.
