Core Component Architecture
The geophone core is the core sensing unit for seismic signal acquisition, using a five-layer composite structure design:
Inertial mass block: Tungsten alloy material (density 19.25g/cm³)
Suspension system: Double helical spring (stiffness coefficient 5N/m±2%)
Electromagnetic conversion component: Neodymium iron boron magnetic circuit (magnetic flux 0.8T)
Damping system: Temperature compensated silicone oil (viscosity 2500cSt)
Base platform: Zero expansion ceramic (CTE＜0.05×10⁻⁶/℃)
Technical Innovation Points
