1. A vibration presentation apparatus, comprising:
a base portion on which a user rides;
a frame on a surface of the base portion, wherein
the frame supports the base portion, and
the frame is perpendicular to the base portion;
a first buffer portion between the base portion and the frame, wherein the first buffer portion is configured to reduce attenuation of vibration in the base portion;
a locking member that extends in a vertical direction from a lower surface of the base portion, wherein the locking member is fixed at a position corresponding to each of four corners of the base portion;
a first vibrating portion on the surface of the base portion, wherein
the first vibrating portion has a first vibration characteristic, and
the first vibrating portion is at a center of gravity of the base portion;
a second vibrating portion on the surface of the base portion, wherein
the second vibrating portion has a second vibration characteristic different from the first vibration characteristic, and
the second vibrating portion is on a first side of the center of gravity; and
a third vibrating portion on the surface of the base portion, wherein
the third vibrating portion has the second vibration characteristic,
the third vibrating portion is on a second side of the center of gravity opposite to the first side of the center of gravity, and
the frame surrounds the first vibrating portion, the second vibrating portion, and the third vibrating portion.
