Abstract

A lithium tantalate (LiTaO3) vibrator comprises a lithium tantalate crystal vibratable in the flexural mode and having an electro-mechanical coupling factor within the range 0.04 to 0.10. The crystal may have a tuning fork shape cut from a Z-plate turned an angle of 48 DEG to 55 DEG around the X-axis.
