Dual-generation mode basketball

The invention discloses a dual-generation mode basketball comprising a ball body, a generation device disposed in the ball body and an energy storage device. The generation device comprises a rack, first generation units and second generation units both mounted on the rack, wherein each first generation unit has a generator and a suspension arm; the suspension arm is connected with a rotor of thegenerator; each second generation unit has piezoelectric ceramic sheets, a piezoelectric ceramic sheet fixing seat, a slide block and a guiding mechanism guiding the slide block to move in a reciprocating way to promote bend and deformation of the piezoelectric ceramic sheets; the piezoelectric ceramic sheet fixing seat is fixed on the rack; and one end of each piezoelectric ceramic sheet is fixedon the piezoelectric ceramic sheet fixing seat and the other end is connected with the slide block. The energy storage device is connected with the first generation unit and the second generation unit via leads. The dual-gene
