本文介绍的压电盘簧换能器，利用结构对应力具有放大作用的原理，通过利用扭矩实现应力放大，可有效地提高换能器的灵敏度。同时通过设计极化的方法使得ｇ１５压电模式得到应用。理论分析和计算结果表明，这种换能器具有很高的灵敏度。
In this paper, the piezoelectric disc spring transducer, using the structure of the principle of amplification with stress, through the use of torque to achieve stress amplification, which can effectively improve the sensitivity of the transducer. At the same time by design polarization method makes g15 piezoelectric mode is applied. Theoretical analysis and calculation results show that this transducer has a high sensitivity.
