Abstract

A vibrating device includes a tubular vibrating body and a lens cover coupled to a first surface of the tubular vibrating body. The tubular vibrating body includes a tubular member and piezoelectric vibrators. The lens cover includes a mode changing coupler and a light transmitting body unit disposed in front of a lens of a camera. The mode changing coupler includes a thin portion having a thickness smaller than a thickness of the tubular member.

First claim

What is claimed is:

1. 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.
