description The invention relates to an air-sound-solid multiple physical field coupling based energy collecting device, and belongs to the technical field of airflow piezoelectric energy change. The energy collecting device comprises an airflow exciting system and an energy change system. The airflow exciting system comprises a nozzle and a resonator, the cuboid nozzle internally includes a cross-section-variable wedge form hole structure, and the inlet area of the nozzle is greater than the outlet area of the nozzle. The resonator includes a semi-closed square cylinder, the top end of the square cylinder is of a wedge shape, and the bottom of the square cylinder includes an enclosed structure. At least two piezoelectric transducers can be vertically fixed in a central line in the inner lower surfaceof the resonator in the cantilever beam form to form array distribution. An energy-storage control circuit is fixed in the outer side of the bottom of the resonator. The piezoelectric transducers areconnected with the energy
