Abstract

This product is a piezoelectric element that uses high-frequency vibrations to remove water droplets adhering to the lens cover of an outdoor camera, etc. Because the product is hollow and circular with a through-hole inside, it can be installed inside an electronic device without obstructing the view of the outdoor camera, etc. The product has an extraction electrode in which part of the electrode printed on the main surface is wrapped around the side and onto the other main surface, allowing electrical connection on only one main surface.
