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).

Abstract: A piezoelectric speaker has a piezoelectric element and vibration plate. The piezoelectric element has a base body with a mounting surface, as well as first and second terminals that are formed on the mounting surface with a distance between them. The vibration plate has a conductive body joined to the piezoelectric element and having a principle surface facing the mounting surface, as well as a first hole with or without a bottom which is formed on the principle surface in a region facing the first terminal to form a space between the body and first terminal. The piezoelectric speaker is capable of preventing the external electrodes of the piezoelectric element from shorting to each other.

Abstract: An electroacoustic transducer has a housing, piezoelectric speaker, dynamic speaker, and support member. The piezoelectric speaker includes a vibration plate having a first surface and a second surface on the opposite side of the first surface, as well as a piezoelectric element joined to at least one of the first surface and second surface, and divides the interior of the housing into a first space facing the first surface and a second space facing the second surface. The dynamic speaker is placed in the first space. The support member is constituted by a part of the housing or by a member different from the housing, has a supporting part facing the first surface or second surface, and supports the periphery of the first surface or second surface with the supporting part.
