SPEAKER SYSTEM AND SPEAKER DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To sufficiently reduce a thickness of a display panel part in a speaker system integrated with a display panel.

SOLUTION: A display panel 40 is inserted inside a bezel 10 and the bezel 10 is supported on the display panel 40. A laminated piezoelectric actuator 70L is attached to the back side of a left side plate part 13 of the bezel 10, and a laminated piezoelectric actuator 70R is attached the back side of a right side plate part 14. The displacement direction (vibration direction) of the stacked piezoelectric actuators 70L and 70R is made the plate surface direction of the bezel 10. Vibration of the laminated piezoelectric actuators 70L and 70R is transmitted to the bezel 10 as longitudinal vibration along the plate surface of the bezel 10 and sound wave is emitted in a front direction perpendicular to the plate surface of the bezel 10.
