To realize a flexible exciter that can be united with a flexible display without compromising their excellent features such as weight reduction, improved storability, and improved impact resistance, a novel bendable electro-acoustic transducer (B.E.A.T.) has been developed employing the viscoelastic polymer as the matrix of 0-3 type piezoelectric composites. By using a pair of flexible exciters attached to the back of a flexible display, the display can make sounds by itself without speaker equipment, which provides the ideal fusion of video and sound like a movie theater.
