Abstract
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.
