The patent filed by Cirrus Logic Inc. describes circuitry for driving a piezoelectric transducer to produce audio output. The circuitry includes pre-processor circuitry to process the input audio signal based on the determined resonant frequency, driver circuitry to generate a drive signal for the transducer, and processor circuitry to determine the resonant frequency. Additionally, the circuitry can include current monitoring, adaptive filter, and error circuitry to optimize the audio output based on the current through the transducer.
Furthermore, the patent details various methods of pre-processing the input audio signal based on the frequency relative to the resonant frequency of the transducer. This includes applying compression, equalization, and dynamic equalization techniques to enhance the audio output. The circuitry can determine the resonant frequency during calibration or continuously during operation, ensuring optimal processing of the input audio signal. Overall, the patent aims to improve the performance of piezoelectric transducers in generating audio output by adapting the processing based on the transducer's resonant frequency.
