摘要： A micro geophone having pole pieces do not extend out around the sides of the magnet, thereby allowing a reduced geophone diameter for a given magnet diameter. The pole pieces are adhesively bonded to the magnet using an adhesive, which may be made suitably electrically conductive by silver or nickel fillers or non-conductive by mica fillers such as borosilicate glass micro-spheres. Axial space is economized by eliminating traditional spider retaining rings. The spider springs are seated directly against the coil form and secured by adhesive fillets disposed on the outward-facing spring circumferences. The spider springs include circumferential notches to receive adhesive. A two-piece bimetallic coil form of aluminum and a heavier material, joined by adhesive, is provided. Headers are affixed to the housing within the seats by adhesive. A straight or rounded chamfer at each of the geophone ends allows the overall geophone dimensions to be maximized.

摘要： The method and the apparatus disclosed serve to acquire seismic induced movements. A coil and a permanent magnet are contained in an enclosure and the seismic movements induce a relative movement between said coil and said magnet. The current induced into the coil is appraised as a measure of said seismic movement. The position of the coil in relation to the permanent magnet is monitored by a position sensor. A closed loop control generates a current that is fed into the coil so that the coil settles at a given neutral position relative to the permanent magnet.

摘要： An illustrative geophone with tunable resonance frequency includes a first inductive assembly including an inductive coil having a first magnet arranged therein, wherein the first magnet and the first inductive coil move relative to each other, and a second inductive assembly including a second inductive coil having a second magnet arranged therein, wherein the second magnet and the second inductive coil move relative to each other. A coupling element couples a movable element of the first inductive assembly with a moveable element of the second inductive assembly. The first inductive assembly employs tunable damping to modify a resonant frequency of the second inductive assembly.
