本文介绍了采用新结构的压电式地听器的工作原理。从等效线路出发,我们导出了地听器的灵敏度公式和频率方程式。分析表明:单位质量灵敏度和质量块的形状关系甚小,而和共振频率的关系较大。合理地选择参数,可获得较高的品质因数。
This article describes the working principle of a piezoelectric structure using a new structure. Starting from the equivalent circuit, we derive the sensitivity and frequency equations of the ground-truth device. The analysis shows that the relationship between unit mass sensitivity and the shape of the mass is very small and the resonance frequency has a great relationship. Reasonable choice of parameters, you can get a higher quality factor.
