Zusammenfassung:	The present disclosure relates to circuitry for driving a piezoelectric transducer to generate an audio output. The circuitry comprises pre-processor circuitry configured to process an input audio signal to generate a processed signal; driver circuitry coupled to the pre-processor circuitry and configured to generate a drive signal, based on the processed signal, for driving the piezoelectric transducer; and processor circuitry configured to determine a resonant frequency of the piezoelectric transducer. The pre-processor circuitry is configured to process the input audio signal based on the determined resonant frequency so as to generate the processed signal.
