Abstract:
(EN) An embodiment comprises: a housing; a bobbin which is placed inside the housing and moves along an optical axis; a coil which is placed on the bobbin and to which a driving signal and a sensing signal are provided; magnets which are placed on the housing; and a position sensor which is placed on the housing. The position sensor senses the position of the bobbin by means of a magnetic field generated by means of the coil. The magnets comprise a first magnet and a second magnet. The position sensor is placed adjacent to the first magnet and/or the second magnet. The position sensor and the first magnet and/or the second magnet do not overlap in the direction from the position sensor to the optical axis.
(FR) Un mode de réalisation de l'invention comprend : un boîtier ; une bobine, qui est placée à l'intérieur du boîtier et qui se déplace le long d'un axe optique ; un enroulement, qui est placé sur la bobine et auquel sont envoyés un signal de commande et un signal de détection ; des aimants, qui sont placés sur le boîtier ; et un capteur de position, qui est placé sur le boîtier. Le capteur de position détecte la position de la bobine au moyen d'un champ magnétique généré au moyen de l'enroulement. Les aimants comprennent un premier aimant et un second aimant. Le capteur de position est placé à côté du premier aimant et/ou du second aimant. Le capteur de position et le premier aimant et/ou le second aimant ne se chevauchent pas dans la direction allant du capteur de position à l'axe optique.
