WIDTH SLIDING PIEZOELECTRIC VIBRATOR

摘要

PURPOSE:To achieve the expansion to a higher frequency operation region and the improvement in the degree of freedom in circuit constitution by so composing a width sliding piezoelectric vabrator that the width of the vibrating part of the width sliding piezoelectric vibrator is mader smaller at both end parts as compared to the central part, and the maximum width is made more than tree times of the thickness, and further electrode pair for excitation and detection of vibrations hold a piezoelectric plate in between and are provided in plural number at the exciting part.
