摘要： A vibration apparatus includes a vibrating body (3) that includes a piezoelectric material having a lead content of less than 1000 ppm, and has electromechanical energy converting means (2, 2a, 2b) having an electrode (9); and control means (100) that apply at least two driving voltages to the electromechanical energy converting means (2, 2a, 2b), and generates a combined vibration by providing a time phase difference to the vibrating body (3) and generating multiple stable waves having mutually different orders; wherein the control means (100) change at least one of the voltage amplitude ratio and time phase difference of at least two driving voltages, so as to change the amplitude distribution of the combined vibration.

摘要： A foreign substance removal unit includes an optical member (410), disposed in an optical path, which is rectangular-shaped and in which an optical effective area for a light flux to pass through is set, and a piezoelectric element (430) including a piezoelectric member (431), and a driving electrode (AF), and a sensor electrode (SF) formed on a surface of the piezoelectric member (431). The piezoelectric element is provided on a surface of the optical member outside the optical effective area and along one side of the optical member (410). The sensor electrode (SF) is formed on the surface of the piezoelectric member (431) to be positioned within a range of the optical effective area in a side direction of the optical member (410) to which the piezoelectric element (430) is provided.
