摘要： In a vibration sensor and a microphone provided in this specification, both ends of a vibration beam are fixed on a base, and a middle portion is suspended in a cavity and generates deformation in response to external vibrational excitation. According to the vibration sensor and the microphone, portions, suspended in the cavity, of a plurality of vibration beams have different dimensions by changing a structure and a dimension of the cavity and a dimension and a position of each vibration beam, so that different vibration beams have different natural frequencies, and resonance peaks of different frequencies are generated under vibrational excitation, forming a wider frequency response range. In addition, a vibration signal selected by the vibration sensor and the microphone is a vibration signal within a preset range near the resonance peak, and sensitivity is higher. Moreover, in the vibration sensor and the microphone, a dimension of the cavity of the base is designed to realize multi-resonance peaks and a wide frequency band. The structure is simple, processing difficulty is low, processing costs are low, and a more accurate collection result of the vibration signal may be obtained.
