In the exp eriment, We developed a free-flood transducer on the principle of coupling betwe en the radial vibration of cylindrical piezoelectric transducer and the liquid c avity vibration, and developed a longitudinal vibrant compound pole transducer o n the principle of coupling between the longitudinal vibration of ceramic and th e bending vibration of front.
实验中 ,为了拓宽换能器的带宽 ,我们利用圆柱形压电换能器的径向振动与液腔振动相耦合原理研制自由溢流式换能器和利用纵向振动与前盖板弯曲振动相耦合原理研制纵向振动复合棒换能器。
