Vibration generating device and electronic device
In accordance with one aspect of the present disclosure, a vibration generating device includes a protruding part; a base provided with the protruding part and formed of a magnetic body; an annular coil surrounding the protruding part; a plate facing the base and formed of a magnetic body; and an elastic member supporting the plate with respect to the base. The plate and the base constitute magnetic circuit.
1. A vibration generating device comprising:
a base;
a coil including an annular shape, the coil being attached to the base;
a plate formed with a magnetic body; and
an elastic member comprising a deformable gel member having a restoring force,
the elastic member supporting the plate with respect to the base,
wherein
the plate includes a surface opposing the base and a projecting part provided with the surface opposing the base,
the projecting part is a weight, and
the projecting part is arranged inside the coil.
2. The vibration generating device according to claim 1 , wherein
the elastic member is deformable in a radial direction.
3. The vibration generating device according to claim 1 , comprising a space inside the elastic member, wherein
the space can accommodate a part of the deformed elastic member.
4. The vibration generating device according to claim 1 , wherein
the elastic member includes an annular shape.
5. The vibration generating device according to claim 1 , wherein
an inner circumferential surface of the coil opposes an outer circumferential surface of the projecting part in a radial direction.
6. An electronic device comprising:
a housing; and
the vibration generating device according to claim 1 .
