Problems solved by technology

[0004] In addition, since the piezoelectric element is fragile, the piezoelectric element may be easily damaged by external impact, so the reliability of sound reproduction is low
Also, when a speaker using a piezoelectric element is applied to a flexible display device, there is a problem of damage occurring due to fragile characteristics of the piezoelectric element

Abstract

The invention provides a vibration apparatus and a vibration generating apparatus including the same. The vibration generating device includes a display panel configured to display an image, a vibration device disposed at a rear surface of the display panel to vibrate the display panel, and an adhesive member and a connecting member between the display panel and the vibration device.

Description

technical field [0001] The present disclosure relates to a vibration device and a vibration generating device including the same. Background technique [0002] The display device displays images at the display panel and includes a separate speaker or sound device for providing sound. When the speaker is located in the display device, the speaker occupies space; therefore, the design and spatial arrangement of the display device are limited. [0003] A speaker applied to a display device may be, for example, an actuator including a magnet and a coil. However, when the actuator is applied to a display device, its thickness is large. Piezoelectric elements that can achieve thinning have attracted widespread attention as embedded speakers. [0004] In addition, since the piezoelectric element is fragile, the piezoelectric element may be easily damaged by external impact, and thus the reliability of sound reproduction is low. Also, when a speaker using a piezoelectric element...
