Vibration presentation apparatus

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.
