Abstract
A method of evaluating a natural frequency of a piezoelectric vibrator including a vibrating membrane and a piezoelectric element, includes: transmitting a drive signal to the piezoelectric element for a certain period of time so as to allow the vibrating membrane to vibrate; acquiring information about a power-generating wave of the piezoelectric vibrator after stopping the transmission of the drive signal to the piezoelectric element; and determining a frequency of the drive wave at which a value of a voltage of the power-generating wave is maximum as the natural frequency of the piezoelectric vibrator, based on the information about the power-generating wave.
