Cascaded structure generator

The present invention discloses a cascade structure generator. Comprising a plurality of vibration generators and vibration generator unit 1 comprises an arcuate friction, arcuate friction unit 2, a concave arcuate inner surface of the friction unit 1 and the arcuate concave surface of the inner friction unit 2 are placed opposite a friction surface, arch shaped outer convex surface friction unit 1 is provided with a support material layer and the electrode, the outer convex surface of the arcuate friction unit 2 is provided with a support material layer and the electrode; and an electrode group comprising a plurality of support material layer matching the vibration generator first geometric shape complementary friction unit, the second geometric shape complementary friction unit; first geometric shape complementary frictional vibration generator unit is connected to two of the support material layer and an electrode and connected thereto, the second geometric shape is complementary to the friction unit and attached thereto and the supporting electrode material layer and the vibration generator is complementary to a vibration generator. The present invention greatly improve the output voltage of the generator, improve the collection and use of environmentally energy.
