Abstract

Un geófono que utiliza un imán Alnico-9 y tiene una sensibilidad mejorada sobre los geófonos Alnico-9 de la técnica previa a través de la longitud del hueco de aire parásito entre las piezas del polo superior e inferior, lo cual resulta en menos fuga de flujo magnético. La concentración de flujo a través de las bobinas del geófono se incrementa y se desplaza hacia los extremos del imán. El incremento de sensibilidad del geófono de la presente invención sobre los geófonos de la técnica previa puede exceder a 3dB. La longitud axial de la bobina enrollada se incrementa, y las posiciones de las bobinas eléctricas se mueven hacia los extremos del imán para alinearse con el flujo magnético desplazado.
