| Abstract: | From the motion equation of the bar which vibrates one-dimensionally and longitudinally, the model of mechanical four-terminal network and the transfer equations are set up, and the natural frequency equation of coniform horn and the ratio of speed of vibration are derived. On this basis, with the help of four-terminal network,the coniform horn working at 20 kHz is designed. |

| Keywords: | mechanical four-terminal network ultrasonic horn transfer parameter |
