N2 - Using the theory of coupled vibrations, the lateral-excitation mode is theoretically analyszed. As a result, a formula for the electromechanical coupling coefficient k31 was derived as a function of the aspect ratio between the width and length of a rectangular thin-plate piezoelectric vibrator. This formula can be used in the design for device fabrication using a lateral-excitation-mode piezoelectric vibrator with an arbitrary aspect ratio.
