Abstract

The present disclosure provides a vibration device and an apparatus including the same, the vibration device including: 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 of the plurality of inorganic portions, the organic portion having a non-piezoelectric property. 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. In addition, an elastic modulus of the first organic portion is lower than an elastic modulus of the second organic portion.

Description

technical field [0001] The present disclosure relates to a vibration device and an apparatus including the same, and more particularly, to an apparatus including a vibration generating device having improved vibration characteristics. Background technique [0002] Display devices display images on a display panel, and separate speakers should be installed to provide sound. When the speakers are provided in the display device, the speakers take up space, so there may be limitations in that the design and spatial arrangement of the display device may be constrained. [0003] Since the sound output from the speaker moves backward or downward from the display device, sound quality may be deteriorated due to interference between sounds reflected from walls or the ground. Therefore, it may be difficult to transmit sound accurately and the immersive experience of the viewer or user may be reduced. SUMMARY OF THE INVENTION [0004] Accordingly, the inventors of the present discl...
