Abstract
Oscillating device including a movable member that is vibratable, a fixed section that is provided opposite to the movable member, a driving unit configured to drive the movable member, and at least two electrodes configured to generate a first signal corresponding to a drive state of the movable member. At least one electrode is provided on the movable member, and at least one electrode is provided on the fixed section. The driving unit can control the driving of the movable member on the basis of the first signal.
