A sound apparatus can include a vibration member; a housing at a rear surface of the vibration member; a connection member disposed between the vibration member and the housing; and a vibration apparatus configured to vibrate the vibration member. The vibration apparatus can include at least one piezoelectric element for producing sound. Also, the connection member can have a first stiffness that is less than a second stiffness of the housing, and the vibration member can be isolated from the housing by the connection member.

Sound apparatus

A sound apparatus may include a vibration member, a housing configured to cover a rear surface of the vibration member, and a vibration apparatus including one or more vibration devices configured to vibrate the vibration member. The vibration member may include a non-planar structure.

Sound apparatus and sound system including the same

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.
