Magnetostrictive film type multi-shock low frequency to high frequency vibration collection and power generation device

The invention discloses a magnetostrictive film type multi-shock low frequency to high frequency vibration collection and power generation device. The device comprises an L-shaped plate (1), a magnetostrictive film layer (2), a stainless steel lining layer (3), a pick-up coil (4), a bar magnet (5), a clapper (9) and a positioning plate (13). The device coil picks up the electric energy generated in the power generation process through the pick-up coil, and realizes the once conversion from once low-frequency shock vibration to repeated high-frequency vibration, thereby causing magnetostrictivematerials to produce repeated high-frequency free vibration to achieve a more efficient process of vibration collection and generation. 磁致伸缩薄膜式多冲击低频转高频的振动收集与发电装置，该装置包括L形板（1）、磁致伸缩薄膜层（2）、不锈钢衬层（3）、拾取线圈（4）、条形磁铁（5）、拍板（9）和定位板（13）；其以拾取线圈拾取发电过程产生的电能，实现了，够将次低频冲击振动转换成多次高频振动，进而使磁致伸缩材料产生多次高频自由振动，达到更高效率的振动收集与发电的过程。
