Float-type wave vibration generating device for magnetostriction slice

The invention relates to a float-type wave vibration generating device for a magnetostriction slice. The overall structure of the float-type wave vibration generating device is a symmetrical structure. The float-type wave vibration generating device comprises a fixing block. A transmission shaft sequentially penetrates through a floating body, a supporting plate, a lower end plate, the fixing block and an upper end plate from bottom to top. The fixing block is fixed to the transmission shaft in an interference-fit mode, and the upper end plate and the lower end plate are connected through a centrosymmetric supporting shaft. Two guide rods penetrate through through holes in the two ends of the fixing block correspondingly. An upper spring and a lower spring are vertically arranged on the guide rods in a sleeving mode. One end of the super-magnetostriction slice is fixed into a rectangular groove in the side face of the fixing block, and the other end of the super-magnetostriction sliceis provided with a mass block. A pick-up coil is wound on the super-magnetostriction slice. The transmission shaft drives the fixing block to swing vertically to provide vibration for the super-magnetostriction slice, electric energy generated in the generating process is picked up through the pick-up coil, and the energy collecting process for converting vibration energy generated in the wave fluctuation motion process into the electric energy to be output is achieved.
