Web12 rows · High sensitivity geophones are usually low frequency geophones, which are more and more widely ... WebGeophones are highly sensitive ground motion transducers that have been used by seismologists and geophysicists for decades. Figure 1shows both an isometric and cross-sectional view of a geophone, which uses the motion of a spring supported coil in the field of a permanent magnet to generate an output signal.
