Vibrating device, method for driving same, and camera

A camera comprising:

• a camera main body including a lens module including a lens positioned at a front end;
• and
• a tubular vibrating body coupled to the lens module and including a tubular piezoelectric vibrator and first and second surfaces that oppose each other;
• wherein
• the tubular piezoelectric vibrator includes a plurality of vibration regions arranged in a circumferential direction thereof and is structured so that among the vibration regions, vibration regions that are adjacent to each other vibrate in opposite phases;
• and
• when the tubular vibrating body is vibrated, the tubular vibrating body vibrates the lens module in a first vibration mode in which the lens provided at the front end has a vibration node in a first region of the lens, the first region corresponding to a field-of-view section of the camera, and a vibration antinode in a second region of the lens, the second region being provided outside the field of view of the camera.
