Abstract: A vibration apparatus may include a vibration plate, a vibration generator at the vibration plate, and a connection member between the vibration plate and the vibration generator. The vibration generator may include a vibration structure. The connection member may include a first connection member between the vibration plate and the vibration structure and overlapping the vibration structure. The connection member may also include a second connection member surrounding the first connection member. A modulus of the first connection member may be greater than a modulus of the second connection member.
