Title: Transducer driving methods and transducer driving systems

Abstract

Transducer driving methods and transducer driving systems are described. According to one aspect, a transducer driving method includes providing a plurality of initial driving signals to a transducer, wherein each of the initial driving signals has a respective one of a plurality of different frequencies, identifying one of the frequencies where the transducer has a reduced impedance as a result of the provision of one of the initial driving signals having the one frequency to the transducer compared with impedances of the transducer resulting from the provision of others of the initial driving signals having others of the frequencies to the transducer, determining that the identified one of the frequencies is not acceptable for driving the transducer, as a result of the determining, identifying another of the frequencies, and driving the transducer using another driving signal having the another frequency.
