ʻO ka geophone kahi mea hoʻololi electromechanical e hoʻohuli i nā nalu seismic i hoʻouna ʻia i ka lepo a i ʻole ka wai i mau hōʻailona uila.He ʻāpana koʻikoʻi ia no ka loaʻa ʻana o ka ʻikepili kahua o nā seismographs.Hoʻohana mau ʻia nā geophones uila i ka ʻimi ʻana i ka ʻāina, a ʻo ka piezoelectric geophones ke hoʻohana mau ʻia i ka ʻimi ʻana i ka seismic o waho.
Hoʻokumu ʻia ka geophone me kahi magnet mau, kahi coil a me kahi lau puna.Loaʻa ka magnetism ikaika a ʻo ia ka mea nui o ka geophone;hana ʻia ka wili me ke keleawe enameled uea ʻeha ma ke kiʻi a loaʻa iā ia ʻelua mau hopena puka.He geophone nō hoʻi ʻO ka ʻāpana kī o ka mea hana;hana ʻia ka ʻāpana puna i ke keleawe phosphor kūikawā i kekahi ʻano a loaʻa kahi coefficient elastic linear.Hoʻohui ia i ka wili a me ka uhi plastik, i mea e hana ai ka wili a me ka magnet i kino hoʻoneʻe pili (kino inertial).Ke loaʻa ka haʻalulu mechanical ma ka honua, neʻe ka coil e pili ana i ka magnet e ʻoki i ka laina ikaika magnetic.E like me ke kumu o ka electromagnetic induction, ua hoʻokumu ʻia kahi mana electromotive i hoʻokomo ʻia i loko o ka coil, a ʻo ka nui o ka ikaika electromotive i hoʻokomo ʻia e like me ka wikiwiki o ka neʻe o ka coil a me ka magnet.ʻO ka hoʻohālikelike o ka hoʻopuka coil Ua kūlike ka hōʻailona uila me ke kānāwai hoʻololi wikiwiki o ka vibration mechanical ground.
ʻO ka EG-4.5-II geophone 4.5Hz he geophone haʻahaʻa haʻahaʻa, a ʻo ka ʻōnaehana coil he ʻano huila wili, hiki ke hoʻopau maikaʻi i ka ikaika hopena lateral.
He kūpono ka geophone no nā ʻano ana ʻano vibration e like me ka geophysical prospecting a me ke ana ʻenekinia vibration.
Hiki ke hoʻohana ʻia ma ke ʻano geophone helu hoʻokahi a me ʻekolu ʻāpana geophone.
ʻElua mau ʻano o ka nalu kū a me ka nalu pae, hiki ke hoʻohana maʻalahi.
Ua like ia me SM-6 B coil 4.5hz geophone.
Hoʻohana nui ʻia i nā ʻōnaehana vibration-monitoring ʻoihana.
ʻO kahi koho kūpono no nā mea hoʻoneʻe shear-hale.
