Abstract

The present description provides a vibration sensor and a microphone. Two ends of each vibration beam are fixed to a base, a middle part thereof is suspended in a cavity, and deformation is generated in response to external vibration excitation. In the vibration sensor and the microphone, by changing the structure and size of the cavity and the size and position of the vibration beams, the sizes of the parts, suspended on the cavity, of the multiple vibration beams are different, so that different vibration beams have different inherent frequencies, resonance peaks having different frequencies are generated under vibration excitation, and therefore a frequency response range is wider. Meanwhile, vibration signals selected by the vibration sensor and the microphone are vibration signals in a preset range near the resonance peaks, so that the sensitivity is higher. Moreover, the vibration sensor and the microphone achieve the purposes of multiple resonance peaks and wide frequency bands by designing the size of the base and the cavity, and the structures thereof are simple, the machining difficulty is low, the machining cost is low and the precision is higher, and a collection result of the vibration signals is more accurate.
