Vibration device

The utility model relates to a vibration device, the on -line screen storage device comprises a base, be provided with on the base under actuating mechanism's drive the upward movement and can be at the pendulum of downstream under self gravity, vibration device still includes when the pendulum moves down by the pendulum striking and the elastic energy storage mechanism of energy storage, striking elastic energy storage mechanism when the pendulum moves down, elastic energy storage mechanism and then carry out the energy storage, drive eccentric device so that pendulum elastic energy storage release of energy of mechanism when shifting up at the motor, a drive power is applyed to the pairing vibration body, reduce the demand to the power of the motor that drives eccentric device, the allupweight that motor belt received has been reduced promptly, messenger's belt not easy slipping just weares and teares lessly. 本实用新型涉及振动装置，包括底座，底座上设置有在驱动机构的驱动下向上运动的并可在自身重力下向下运动的振动体，振动装置还包括在振动体下移时被振动体撞击而储能的弹性储能机构，当振动体下移时撞击弹性储能机
