Title:
振動発生装置及びこれを備えた電子機器
Document Type and Number:
Japanese Patent JP6462533
Kind Code:
B2
Abstract:
The invention provides a vibration generator with enhanced magnetic attraction force of a coil applied to a plunger. A vibration generator S includes a coil 100, a plunger 200, and a frame 300. The plunger 200 includes a first shaft 210 movably received in the coil 100. The first shaft 210 is at least partly made of a magnetic material so as to be magnetically attractable to the coil 100 and thereby movable in the Y-direction. The plunger 200 further includes a second shaft 220 extending in a X-X' direction, being disposed on a Y'-direction side relative the coil 100 with a gap therebetween, and being at least partly made of a magnetic material to be magnetically attractable to the coil 100 and thereby movable in the Y-direction. The frame 300 is fixed to the first shaft 210 at a position on the Y-direction side relative to the coil 100, fixed to the second shaft 220 at a position on the Y'-direction side relative to the coil 100, and elastically deformable at least partly as a result of movement of the first shaft 210 and the second shaft 220.
