Abstract
In an embodiment, a surface of a smartphone 10 is covered with a transparent protective panel 22 supported by rims 16 of a housing 12, and a display device 18 and touch panel 20 are placed in a storage part 14 of the housing 12. The protective panel 22 is constituted by joining a glass plate 22A and resin plate 22B together, and concave parts 30A, 30B are provided on the joining surface side of the resin plate 22B, with piezoelectric vibrating elements 40 placed therein and joined to the glass plate 22A, wherein vibration is transmitted to the surface of the protective panel 22 as surface acoustic waves, demonstrating a haptic function, and also, audible vibration is generated because the modulus of elasticity of the resin plate 22B is lower than that of the glass plate 22A, achieving an operation as a speaker (or receiver).
