Piezoelectric vibrating strip, piezoelectric vibrator, oscillator, electronic device, and radio timepiece
Abstract:
A piezoelectric vibrating strip includes a pair of vibrating arm portions in parallel with a central axis therebetween, and a base portion integrally cantilevering base end portions of the pair of vibrating arm portions in a length direction. Each of the pair of vibrating arm portions has a first groove portion and a second groove portion in a main face, the first groove portion being placed closer to a leading end portion in the length direction of the vibrating arm portions and having a groove width along a width direction orthogonal to the length direction and a thickness direction of the vibrating arm portion. The second groove portion is closer to the base end portion than the first groove portion and has a groove width along the width direction. The groove width ratio of the second groove portion to the first groove portion is between 0.4 and 1.0.
Abstract(Chinese):

压电振动片包括与它们之间的中心轴线平行的一对振动臂部分，以及在一对振动臂部分的长度方向上整体地悬置基部端部的基部。 所述一对振动臂部中的每一个在主面上具有第一槽部和第二槽部，所述第一槽部在所述振动臂部的长度方向上靠近前端部配置，并且沿着 与长度方向正交的宽度方向和振动臂部的厚度方向。 第二槽部比第一槽部更靠近基端部，并且沿宽度方向具有槽宽。 第二槽部与第一槽部的槽宽比为0.4〜1.0。
