The 80khz 60W ultrasonic transducer oscillator includes a piezoelectric ceramic chip with electrodes on it; The piezoelectric ceramic chip is fixedly packaged in an insulating material, and the combination of the shape and packaging method of the piezoelectric ceramic chip led out by the electrode from the insulating material mainly has three forms: 1. The piezoelectric ceramic chip is in a circular shape, and the piezoelectric ceramic chip is fully surrounded and fixedly packaged by the insulating material; 2. The piezoelectric ceramic chip is a circular ring, and the piezoelectric ceramic chip is fully surrounded and fixed by insulating materials for packaging; 3. The piezoelectric ceramic chip is circular in shape, and after being fixed and encapsulated by insulating materials, the central part of one side of the piezoelectric ceramic chip is exposed (i.e. semi enclosed), and the exposed part is the radiation surface of the oscillator. The radiation surface can be conical. The insulation material of this utility model is a high-strength, low damping insulation material, such as phenolic resin. This utility model uses high-strength and low damping insulation materials to fully or partially encapsulate and fix piezoelectric ceramic chips, eliminating the need for metal iron blocks, thereby reducing the volume of the transducer oscillator and reducing its weight. At the same time, the manufacturing cost of the oscillator is reduced, and the manufacturing process is simple.
