More Information
Summary:The piezoelectric device includes an integral body of piezoelastic material with its length and width being larger than height. The device also includes each pair of electrode contacted to the integral body. Each pair of electrode is in contraposition along direction of thickness. When voltage is applied to pairs of electrode, the integral body is deflected along traverse direction. The invention also discloses cantilever piece of disc drive, and spring leaf subassembly of magnetic head.
