1. A vibration system, comprising:
a vibration plate and an edge portion around the vibration plate, wherein
the vibration plate has a first region and a second region,
a shape of the first region is asymmetrical with a shape of the second region,
a curvature of a first curve that configures an outer edge of the first region is different from a curvature that configures an outer edge of the second region,
the outer edge of the first region is opposite to the outer edge of the second region with respect to a division line,
the vibration plate is configured such that a weight difference between the first region and the second region is equal to or smaller than a threshold value, and
a stiffness at the edge portion is substantially uniform.
