Websi.wikipedia.org A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the earth. See more The term geophone derives from the Greek word "γῆ (ge) " meaning "earth" and "phone" meaning "sound". See more The frequency response of a geophone is that of a harmonic oscillator, fully determined by corner frequency (typically around 10 Hz) and damping (typically 0.707). Since the … See more • Accelerometer • Hydrophone • Michelson interferometer See more Geophones have historically been passive analog devices and typically comprise a spring-mounted wire coil moving within the field of a case-mounted permanent magnet to generate an electrical signal. Recent designs have been based on The response of a … See more The majority of geophones are used in reflection seismology to record the energy waves reflected by the subsurface geology. In this case the primary interest is in the vertical motion of the Earth's surface. However, not all the waves are upwards travelling. … See more • PSR-1 Seismic Intrusion Detector (Vietnam era military device) See more
