A vibration device can include a vibration portion, a first electrode portion disposed on a first surface of the vibration portion, and a second electrode portion disposed on a second surface of the vibration portion. Also, each of the first electrode portion and the second electrode portion includes a conductive metal particle and a piezoelectric nanoparticle.

Vibration device and apparatus including the same

Discussed is an apparatus including a display panel configured to display an image, a vibration apparatus disposed at a rear surface of the display panel to vibrate the display panel to generate sound, and an adhesive member and a connection member between the display panel and the vibration apparatus. The vibration apparatus can include a vibration portion, a first protection member disposed at a first surface of the vibration portion, and a second protection member disposed at a second surface of the vibration portion, the second surface of the vibration portion being different from the first surface of the vibration portion. The connection member can cover a front surface of the first protection member adjacent to the adhesive member.

Vibration apparatus and apparatus including the same

An apparatus can include a display member configured to display an image, a vibration apparatus disposed at a rear surface of the display member, a supporting frame disposed at a rear surface of the vibration apparatus, and an adhesive member disposed between the supporting frame and the rear surface of the display member. In addition, the adhesive member and/or supporting frame is spaced apart from the vibration apparatus, and the vibration apparatus is configured to vibrate in a direction toward the display member.

Apparatus

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.

A vibration device can include a vibration portion; a first electrode portion disposed on a first surface of the vibration portion; and a second electrode portion disposed on a second surface of the vibration portion, in which each of the first and second electrode portions include at least one of a conductive metal particle and a carbon particle.

Discussed is an apparatus including a display panel configured to display an image, a vibration apparatus disposed at a rear surface of the display panel to vibrate the display panel and to generate sound via the display panel, and an adhesive member and a connection member between the display panel and the vibration apparatus.
