Abstract
A transducer comprises two piezoelectric layers attached to a substrate, two protective layers, two masses, and two stiffeners arranged at the ends of the bimorph. The transducer is made using a composite bagging process and autoclave curing. The transducer is attached to a flat panel using a parallelogram-shaped double-sided tape to form a loudspeaker or a display panel with haptic feedback. The improved transducer enables a full-range flat panel speaker with uniform frequency response over its operating frequency.
