The transducer comprises seven layers of structures which are sequentially arranged from top to bottom, the first layer of structure and the fifth layer of structure are pure electrode layers or composite electrode layers, and the second layer of structure, the fourth layer of structure and the sixth layer of structure are pure piezoelectric layers. The third-layer structure and the seventh-layer structure are both composite electrode layers or pure electrode layers, and each composite electrode layer comprises an electrode and an insulation gap. The transducer provided by the invention has extremely low electric power consumption, the power consumption of the transducer is reduced, the ultrasonic output sound power of the transducer is improved, and particularly, the transducer has huge practical value in the scenes of low-power consumption and high-sound power output application, small-size application, high-frequency ultrasonic application and the like; and innovation and realization of industrial ultrasou
