    摘要: In a piezoelectric device, a first electrode and a second electrode are disposed to be opposed to each other on plate surfaces of the piezoelectric device, a first electrode plane of the piezoelectric device is fixedly bonded to a plate surface of a vibrating plate, a piezoelectric material forming the piezoelectric device is polarized in a direction parallel to the first electrode plane, the piezoelectric device is fixed to a base through a second electrode plane of the piezoelectric device, and the piezoelectric device generates a thickness-shear vibration with the fixed second electrode plane being a reference plane. The piezoelectric vibration generated by the piezoelectric device generates a flexural vibration in the vibrating plate, to thereby remove dust adhering to a surface of the vibrating plate.

    摘要: Provided is a vibration generating device in which more improvement of drive efficiency can be realized than conventional ones. The vibration generating device includes: a piezoelectric element including a piezoelectric material interposed between electrodes; a vibration member; a power source for applying an alternating voltage to the piezoelectric element; and a control section for controlling a frequency of the alternating voltage applied by the power source, in which the control section controls the frequency of the alternating voltage applied to the piezoelectric element so that the resonance frequency of the piezoelectric element is successively changed from low frequency side to high frequency side in a frequency range including a change range of a resonance frequency of the piezoelectric element.
