VIBRATION PIECE, SENSOR UNIT AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a vibration piece capable of suppressing leakage output without lowering mechanical strength and also to provide a sensor unit and an electronic apparatus equipped with the vibration piece.SOLUTION: A vibration piece includes: a base part; driving vibration arms extending from one end of the base part; detecting vibration arms extending from the other end on the side opposite to one end of the base part; adjusting vibration arms extending from the base part to the side opposite to the driving vibration arms; and support parts extended from the base part and fixed to a substrate. An output signal of the adjusting vibration arms has an inverse phase with respect to the output signal of leakage vibration of the detecting vibration arms.
