A buzzer driving system includes a filter circuit and a driving circuit. The filter circuit is configured to filter an audio playback signal and output an analog playback signal. The driving circuit is electrically connected to the filter circuit and configured to output a driving voltage to the buzzer based on the analog playback signal. The driving system generates the driving voltage in an analog form to enhance the output audio quality of the buzzer.

A buzzer driving system is electrically connected to a buzzer and includes a driving unit, a boost unit, and a gain estimation unit. The driving unit includes a gain control circuit that adjusts the gain of an audio signal based on a gain factor and outputs a driving voltage to the buzzer based on the adjusted audio signal. The boost unit is electrically connected to the driving unit and boosts an input voltage to generate a working voltage for the driving unit. The gain estimation unit is electrically connected to both the driving unit and the boost unit and is configured to generate a plurality of stepwise voltages based on the working voltage. The gain estimation unit sequentially compares the input voltage with each of the stepwise voltages to generate an estimated gain. The gain factor used by the gain control circuit is determined based on this estimated gain.
