A vibration device can include a vibration generator including a vibration portion, in which the vibration portion includes a plurality of inorganic portions having piezoelectric characteristics, the plurality of inorganic portions being spaced apart from each other; and an organic portion disposed between at least two inorganic portions among the plurality of inorganic portions, the organic portion having non-piezoelectric characteristics. The organic portion includes a first organic portion and a second organic portion, the first organic portion being disposed between one of the plurality of inorganic portions and the second organic portion. Further, an elastic modulus of the first organic portion is lower than an elastic modulus of the second organic portion.

Vibration device and apparatus including the same

A display apparatus includes a display panel configured to display an image, and a vibration device on a rear surface of the display panel to vibrate the display panel to generate a sound, the vibration device including a vibration array including a plurality of vibration modules.

Display apparatus

A vibration apparatus can include a first cover member; a second cover member; a vibration portion between the first cover member and the second cover member; a contact portion between the first cover member and the vibration portion; and a signal cable. The signal cable can include a first signal line connected to a first surface of the vibration portion via the contact portion, and a second signal line connected to a second surface of the vibration portion opposite to the first surface of the vibration portion.

Vibration apparatus and apparatus including the same
