A nebulizing driving apparatus (10) is used to drive a piezoelectric material (202) of a nebulizing module (20). The nebulizing driving apparatus (10) includes a driving circuit (102), a control circuit (104) and a feedback circuit (106). The feedback circuit (106) detects an electrical data (206) fed back from the piezoelectric material (202) and sends the electrical data (206) to the control circuit (104), at first when the piezoelectric material (202) is activated with a test driving frequency. According to the electrical data (206) values, which may be voltage, and possibly corresponding to a plurality of reading with different test driving frequencies, the control circuit (104) determines a a working frequency, under which it will let the driving circuit (102) drive the piezoelectric material (202). |
