Abstract
A piezoelectric vibrator and an ultrasonic motor having the piezoelectric vibrator. A piezoelectric vibrator has a multilayered piezoelectric actuator, with special internal and surface electrodes making the body vibrate in a longitudinal and bending direction when an electrical signal is inputted. It can be manufactured using conventional multilayer piezoelectric actuator manufacturing techniques, therefore, it has reduced manufacturing time and cost, as it is not necessary to go through two polarization processes, and may simplify and decrease the volume, while improving the vibration performance.
