AB  - The method for avoiding the large displacement damage problem of the transducer diaphragm is presented in this study. To account for the displacement and supply current, a set of transduction equations with parameters for the receiver is established. The numerical solver is used to obtain the displacement values from the transduction equations of the transducer and then limit the peak of the current and coil velocity by using the dynamics limiter. Once the peak limited process is done, the safe input voltage can be obtained satisfactorily for preventing the impulse damage of displacement. The numerical and experimental results indicate that the proposed method features high efficiency and ability applied in the wide application of transducers.
