Abstract
A display device structure comprising a casing, a display panel placed in the casing, a transparent covering and vibrating plate member on the front side of the display panel and an actuator for the plate member. The covering and vibrating plate member is carried on the casing through an elastic member interposed between the peripheral portion of the plate member and the casing. By this arrangement the plate member is capable of effectively generating sound outward upon reception of vibrating force from the actuator.
