Example Embodiment
[0033] Example 1
[0034] This embodiment is mainly aimed at the situation where the external input vibration frequency is lower than 50 Hz. Such as figure 1 As shown, this embodiment includes: an upper vibration pickup table 1, a gasket 2 and a lower vibration pickup table 3. The spacer 2 is located between the upper vibration pickup table 1 and the lower vibration pickup table 3.
[0035] Such as figure 1 , 2 As shown, the upper vibration pickup table 1 includes: a top cover 4, a metal plane spring 5, and a permanent magnet 6. There is a pit in the center of the top cover 4, and the metal plane spring 5 is fixed on the edge of the pit of the top cover 4, and includes a central metal platform 8 and two cantilever beams 7 around it. The permanent magnet 6 is located on the metal platform 8 directly above the vibration pick-up table 3 in the lower layer.
[0036] The depth of the pits on the top cover 4 is 200 μm to 400 μm, and the side length is 3 mm to 5 mm. Can be made of mate...
Example Embodiment
[0051] Example 2
[0052] This embodiment mainly addresses the situation where the external input vibration frequency is higher than 50 Hz and lower than 200 Hz. Such as image 3 As shown, this embodiment includes: an upper vibration pickup table 1, a gasket 2 and a lower vibration pickup table 3. The spacer 2 is located between the upper vibration pickup table 1 and the lower vibration pickup table 3.
[0053] Such as image 3 , 4 As shown, the upper vibration pick-up table 1 includes: a top cover 4, a metal plane spring 5 and a permanent magnet 18. There is a pit in the center of the top cover 4, and the metal plane spring 5 is fixed on the edge of the pit of the top cover 4, and includes a central metal platform 20 and four cantilever beams 19 around it. The permanent magnet 18 is located on the metal platform 20, directly above the vibration pickup platform 3 at the lower level.
[0054] The depth of the pits on the top cover 4 is 200 μm to 400 μm, and the side length is 3 mm to...
