The present disclosure provides a differential resonator and a MEMS sensor. The differential resonator includes a substrate, a first resonator, a second resonator and a coupling mechanism. The first resonator is connected with the second resonator through the coupling mechanism, and the first resonator and the second resonator are connected with the substrate and are able to be displaced relative to the substrate. The coupling mechanism includes a coupling arm, a support shaft, a first connecting piece and a second connecting piece. The coupling arm includes a first force arm, a second force arm and a coupling portion. The support shaft has one end connected with the substrate, and one other end connected with the coupling portion. The first force arm is connected with the first resonator through the first connecting piece, and the second force is connected with the second resonator through the second connecting piece.

Differential resonator and MEMS sensor

The present disclosure provides a differential resonator and a MEMS sensor. The differential resonator includes a substrate, a first resonator, a second resonator and a coupling mechanism. The first resonator is connected with the second resonator, and the first resonator and the second resonator are movably connected with the substrate. The coupling mechanism includes a first guide beam, a second guide beam, a first coupling beam, a second coupling beam, a first connecting piece and a second connecting piece. The first guide beam and the second guide beam are arranged on two opposite sides of a direction perpendicular to a vibration direction of the first resonator or the second resonator. The first coupling beam is connected with the first guide beam, the second guide beam and the first resonator. The second coupling beam is connected with the first guide beam, the second guide beam and the second resonator.
