Abstract


Geophone is a kind of typical seismic sensors, after years of development, the structure and technology has been quite mature, but in recent years, with the development of measuring needs for micro-seismic events, the traditional geophone appeared insufficient, this article through the analysis and Research on its structural principle, based on the similarity principle of electric system and mechanical system and circuit model of this type of detector is established by Multisim software of NI (National Instruments), and it is validated by the corresponding simulation results.

Keywords
