| description | The invention discloses a non-contact frequency raising mechanism vibration energy collector. The energy collector comprises a movable pedestal, a fixed beam, an upper side piezoelectric single crystal composite cantilever beam and a lower side piezoelectric single crystal composite cantilever beam, the fixed beam is used for responding to low-frequency vibration and comprises a beam main body, an upper side magnet and a lower side magnet; the upper side piezoelectric single crystal composite cantilever beam and the lower side piezoelectric single crystal composite cantilever beam are used for responding to high-frequency vibration and each comprise a cantilever beam body, a cantilever beam magnet and a piezoelectric plate, wherein the cantilever beam magnet and the piezoelectric plate are arranged on the cantilever beam body. The cantilever beam magnets respectively form magnetic action with the upper side magnet and the lower side magnet, so that when the fixed beam receives external low-frequency vibration |
