The application discloses a flexible micro-
beam resonator with a mode limiting device working in a high-order mode, which comprises a substrate, a driving
electrode, a flexible
cantilever micro-beam, an upper
limiter, a lower
limiter and a shell cover, the shell cover is fixed on the substrate, the flexible
cantilever micro-beam is fixed on the substrate and located between the shell cover and the substrate, the upper
limiter is installed between the flexible
cantilever micro-beam and the shell cover, the lower limiter is installed between the flexible cantilever micro-beam and the substrate, the driving
electrode is fixed on the substrate and located between the flexible cantilever micro-beam and the substrate, and the flexible cantilever micro-beam further comprises a fixed micro-beam, one end of the fixed micro-beam is connected below the flexible cantilever micro-beam, and the other end of the fixed micro-beam is connected above the substrate, the flexible cantilever micro-beam vibrates at an Nth
natural frequency, and N is greater than or equal to 2, and the application is suitable for the micro-
beam resonator working in the high-order mode, the zero point of the high-order vibration mode function is utilized, the limiters are arranged at the zero point, and the one-way and bidirectional limiting functions are completed.
