A vibration transducer such as a geophone, comprising a central pole piece (110) with a magnet (112) and coil (118) concentrically arranged around it. The position of the magnet (112) is fixed relative to the pole piece (110) and the coil (118) is movable relative to the magnet (112). A method of manufacturing a vibration transducer is characterised in that a bobbin carrying the coils is formed from a substantially tubular body which is positioned on a mandrel and at least one coil is wound around its outer surface, the mandrel being removed from the bobbin when the coil is complete. Another method is characterised in that the coil is formed separately and the bobbin is formed from a substantially tubular body which is positioned inside the coil and expanded to contact the coil when in position.

L'invention concerne un capteur de vibrations tel qu'un géophone, qui comprend une pièce polaire centrale (110) avec un aimant (112) et un enroulement (118) placés de manière concentrique autour d'elle. La position de l'aimant (112) est fixe par rapport à la pièce polaire (110) et l'enroulement (118) est mobile par rapport à l'aimant (112). Un procédé de fabrication d'un capteur de vibrations est caractérisé en ce qu'une bobine supportant les enroulements est formée à partir d'un corps sensiblement tubulaire qui est placé sur un mandrin et en ce qu'au moins un enroulement est enroulé autour de sa surface extérieure, ledit mandrin étant retiré de la bobine lorsque l'enroulement est achevé. Un autre procédé est caractérisé en ce que l'enroulement est formé séparément et en ce que la bobine est formée à partir d'un corps sensiblement tubulaire qui est placé dans l'enroulement et s'étend pour entrer en contact avec l'enroulement lorsqu'il est en position.
