Abstract

The invention relates to a vibration device and equipment comprising the same. A vibration device includes a vibration portion, a first electrode portion disposed at a first surface of the vibration portion, and a second electrode portion disposed at a second surface of the vibration portion, where the first electrode portion and the second electrode portion include at least one of conductive metal particles and carbon particles.

Description

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