Abstract
The present invention provides a transducer protection system and method. A transducer module at least comprises a transducer, and a signal source is used for generating a first signal; a protection module is used for predicting an actual displacement and/or temperature of the transducer according to the first signal, an amplification factor of the power amplifier and built-in transducer parameters to generate a prediction result, comparing the prediction result with a preset value to generate an analysis result, and regulating the first signal to form a second signal according to the analysis result; a power amplifier is used for receiving the second signal, and performing power amplification on the second signal to form a driving signal; and the transducer module is used for receiving the driving signal, and at least one transducer in the transducer module can work according to the driving signal.
