<p>An AV device (10) is provided with a piezoelectric film (20), an exciter film (30), a display panel (40), and a securing member (50). The piezoelectric film (20) has a shape ranging over approximately the whole surface of one principal surface of the exciter film (30), and attached to the one principal surface of the exciter film (30). The securing member (50) is attached to both end sides orthogonal to the expansion/contraction direction of the piezoelectric film (20) in the exciter film (30). The securing member (50) is secured to both end sides facing each other of the display panel (40). Consequently, both the end sides of the display panel (40) are secured to both the end sides orthogonal to the expansion/contraction direction of the piezoelectric film (20) in the exciter film (30). In this case, the display panel (40) is secured to the exciter film (30) so as to have a shape curved and protruding to the opposite side to the side where the exciter film (30) is present.</p> |
