VIBRATION GENERATOR AND ELECTRONIC DEVICE HAVING THE SAME

摘要

A vibration generator including a coil, a plunger including a first shaft and a second shaft, and a frame. The first shaft is received in the coil such as to be movable in a first direction. The second shaft extends in a second direction orthogonal to the first direction, is disposed on the other side in the first direction relative to the coil with a gap therebetween. The first and second shafts are partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to one side in the first direction. The frame is fixed to the first and second shafts at positions on the one and other sides, respectively, in the first direction relative to the coil, and elastically deformable at least partly as a result of movement of the first and second shafts.

1. A vibration generator comprising:
a coil; a plunger including:
a first shaft received in the coil such as to be movable in a first direction and at least partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to one side in the first direction, anda second shaft extending in a second direction orthogonal to the first direction, being disposed on the other side in the first direction relative to the coil with a gap therebetween, and being at least partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to the one side in the first direction; and a frame fixed to the first shaft at a position on the one side in the first direction relative to the coil, fixed to the second shaft at a position on the other side in the first direction relative to the coil, and elastically deformable at least partly as a result of movement of the first and second shafts.
