Title:
RESONANCE DEVICE AND METHOD FOR MANUFACTURING RESONANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/213213
Kind Code:
A1
Abstract:
The present invention provides a resonator and a device that can improve resonator characteristics while suppressing an increase in dimensions. A resonator 13 comprises a vibration part 15 that performs contour vibration, a holder 14 that is formed to surround at least some of the vibration part 15, and supports 16a, 16b that extend in the Y-axis direction and connect the vibration part 15 and the holder 14. The vibration part 15 includes a through hole 27 that extends along the X axis direction, which is orthogonal to the Y axis direction, so that a linking part 28 is formed between the supports 16a, 16b. The X-axis-direction length SL in the through hole 27 is greater than the Y-axis-direction length Sd in the linking part 28.
