Abstract:
1. A touch panel display comprising: a flat plate-shaped movable panel unit having a display panel and a touch panel integrally stacked over a display surface of said display panel; a movable support member being elastic and supporting said movable panel unit over a support structure so that said movable panel unit can be displaced in the thickness direction thereof; an acoustic vibration unit provided between a back surface, fronting on said support structure, of said movable panel unit and said support structure, the acoustic vibration unit including an actuator vibrating when supplied with a driving signal; and a soft member provided between said touch panel of said movable panel unit and said actuator, and being put into a compressed state when a front surface of said touch panel is depressed and into a non-compressed state when said front surface of said touch panel is not depressed, said acoustic vibration unit including: a sound generating member for generating a sound by vibrating; and a hard member connecting said sound generating member and said actuator to each other and transmitting the vibration of said actuator to said sound generating member, an actuator drive control unit being provided for supplying said driving signal to said actuator, said vibration of said actuator being transmitted to said movable panel unit through said soft member when said soft member is in said compressed state, and said vibration of said actuator being not transmitted to said movable panel unit when said soft member is in said non-compressed state, because of intermediate presence of a space between said soft member and said back surface of said movable panel unit, or because of absorption of said vibration by said soft member.
