A drum-type wide-frequency piezoelectric power generation apparatus. A protective layer is adhered to a piezoelectric layer by means of an epoxy resin adhesive or another electrically conductive adhesive. The piezoelectric layer is adhered to a foundation layer by means of an epoxy resin adhesive or another electrically conductive adhesive. Piezoelectric oscillator ends distal to first permanent magnets are fixed to an end cap a by means of fastening devices. The end cap a is provided with an octagonal boss a. The surface of the boss a is provided with a boss b, a boss c, and a boss d, and four piezoelectric oscillators are fixed to the sides of the boss a, the boss b, the boss c, and the boss d, respectively. There are four slots corresponding to four sides of the piezoelectric oscillators fixed to the four bosses, each slot being used to hold in place the fastening devices. Auxiliary magnets are closer to the center of an end cap b than second permanent magnets are, each second permanent magnet being provided with a corresponding auxiliary magnet. The first permanent magnets and the second permanent magnets are mutually repelling, and the auxiliary magnets and the first permanent magnets are mutually repelling. |
