Abstract
A vibration reduction device configured to reduce vibration perceived by an occupant of a mobile object includes a vibration generator and a control device. The control device is configured to control drive of the vibration generator. The control device is configured to detect a direction, an amplitude, and a phase of swing of a head of the occupant. The control device is configured to set a sound pressure of air vibration to be generated by the vibration generator based on the direction and the amplitude of the swing. The control device is configured to set a phase of the air vibration based on the phase. The control device is configured to control the drive of the vibration generator to generate the air vibration based on the set sound pressure and the set phase.
