Device produces relative motion.When piezoelectric vibrator and extruding ball are gone to when being contacted with driver, ball and driver phase mutual connection are extruded
Touch and produce lateral compression power, extruding ball forces piezoelectric vibrator to the direction flexural deformation away from driver；When extruding ball
When overlapping with the center of driver, the metal cantilever beams of piezoelectric vibrator are acted against on confined planes completely, piezoelectric vibrator deflection most
Greatly；Hereafter, the deflection of piezoelectric vibrator is gradually reduced with the rotation of rotating disk, and piezoelectricity shakes when extruding ball is mutually disengaged with driver
The deflection of son is zero, returns to nature；After above-mentioned extruding ball is in contact with driver and during disengaging, pressure
Electric tachometer indicator completes a power generation process；Electric energy produced by piezoelectric vibrator through wire transmission to LED, LED obtain it is electric after send out
Light.
Advantage and characteristic：The relative motion between rotating disk and driver is realized using inertia force and encourages piezoelectric vibrator axially curved
Song deformation generates electricity, it is not necessary to which extra setup fixes support；Each point stress is identical after piezoelectric vibrator deformation and is subjected only to compression, therefore
Generated energy is big, reliability is high；The Warning light of bicycle energy-autarchic that is formed, do not need battery, it is energy-conserving and environment-protective, easy to use.
