ACTIONNEUR LINÉAIRE VIBRANT, DISPOSITIF DE COUPE DE CHEVEUX, ET PROCÉDÉ DE FABRICATION D'UN ACTIONNEUR LINÉAIRE VIBRANT

摘要

An oscillatory linear actuator (100) includes an electromagnetic core block (200) including an electromagnet (electromagnetic part (210)), and a magnetic block (300) that holds permanent magnets (301, 302) so that the permanent magnets face the electromagnet with a predetermined space in between. The electromagnetic core block integrally includes a core (240), a coil bobbin (220), and a base (250), the core and the coil bobbin forming the electromagnet, and the base holding the core and the coil bobbin. The magnetic block includes the permanent magnets (301, 302) and a frame (400) that holds the permanent magnets so as to allow the permanent magnets to oscillate freely and holds the electromagnetic core block. The frame has a guide portion (450) that guides the electromagnetic core block to adjust a positional relation of the permanent magnets and the electromagnet, and the base is fixed to the frame inside the guide portion.
