Abstract
An electronic device includes a transducer including a sensing area and a covering structure that covers the transducer. The covering structure includes a shelter portion and defines at least one aperture. The shelter portion covers the sensing area. The aperture includes a first curved surface and a second curved surface farther away from the sensing area than the first curved surface, and a first center of a first curvature of the first curved surface is at a different location than a second center of a second curvature of the second curved surface.
