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.

    本发明公开了一种线性振动器、摇摆装置、婴儿床及线性振动器的控制方法,涉及振动技术领域,该线性振动器包括偏心轮组和驱动装置。偏心轮组包括质量相同的第一偏心轮和第二偏心轮。驱动装置用于驱动所述第一偏心轮和所述第二偏心轮同速反向转动,所述第一偏心轮的转动轴线为第一轴线,所述第二偏心轮的转动轴线为第二轴线,所述第一轴线和所述第二轴线平行或者重合。所述第一偏心轮的第一质心与所述第一轴线之间的距离等于所述第二偏心轮的第二质心与所述第二轴线之间的距离。本发明通过驱动装置驱动偏心轮组实现线性的振动,其结构简单,成本低,相比于传统的线性振动马达,驱动效率更高,能够产生更低频率的振动。
