Abstract
A resonator includes a resonating body and at least one periodic structure having one end connected to the resonating body. The periodic structure includes at least two basic structure units with duplicated configuration. The periodic structure blocks wave propagation caused by the vibration of the resonating body. The resonating body has a resonance frequency f0. The periodic structure has a band gap characteristic or a deaf band characteristic within a particular frequency range, and the resonance frequency f0 falls within the particular frequency range of the periodic structure.
