A new type of high sensitivity, high damping and low output impedance composite geophone has been developed. By using the microelectronic technology to increase the geophone damping ratio coefficient, the frequency characteristics of the main frequency region of the geophone can be modified, The results of field test show that this detector has the advantages of high signal-to-noise ratio, high video frequency and high energy, widening seismic wavelet frequency band and improving the main frequency, and is suitable for high resolution Use of seismic exploration.
