Publication number: 20250023550Abstract: A resonator includes a first sub-resonator and a plurality of second sub-resonators. The first sub-resonator in vibration deforms in at least two non-parallel directions. The first sub-resonator is connected to the second sub-resonators in all the at least two non-parallel directions, and deformations in all the at least two non-parallel directions couple the first sub-resonator to the second sub-resonators. Then, the resonator can balance a Q value and Rm, and can have a higher Q value and lower Rm.Type: ApplicationFiled: September 30, 2024Publication date: January 16, 2025Inventors: Fengpei Sun, Zhihong Feng, Jinghui Xu, Linhai Huang
