中、被覆部材１０ば一部のみを切欠いて示している。FIG. 1 is a perspective view showing a piezoelectric speaker according to the present invention. This piezoelectric speaker 1 has a rectangular shape in which the horizontal dimension is longer than the vertical dimension, and has a structure in which a plurality of piezoelectric drivers 3 (five in the illustrated example) are embedded inside a diaphragm 2. The peripheral edge of the diaphragm 2 is held by a picture frame-like frame 4, and the entire front side of the piezoelectric speaker 1 including the frame 4 is covered with a covering member 10. This covering member 10 is selected from the same material as the wallpaper or the like covering the wall surface on which the piezoelectric speaker 1 is to be installed. In the figure, only a portion of the covering member 10 is shown cut away.

ため、壁面２０と一体化する。On the other hand, a mounting portion 6 for accommodating the piezoelectric speaker 1 is recessed in the wall surface 20. The mounting portion 6 has a vertical dimension that is slightly smaller than the vertical dimension of the piezoelectric speaker 1, and a depth that is such that an appropriate space is secured on the back side of the piezoelectric speaker 1 to be housed. When storing the piezoelectric speaker 1 in the mounting part 6, the wall surface 20 and the surface of the piezoelectric speaker 1 are flush with each other, and the upper and lower ends of the piezoelectric speaker 1 are attached to the mounting part 6 using adhesive or the like. Attach to the top and bottom surfaces. by this,
The piezoelectric speaker 1 is embedded in the mounting portion 6, and its surface is covered with the same covering member 10 as the wall surface 20, so that it is integrated with the wall surface 20.
