A haptic signal can be generated using an intermediate state of a plurality of generation algorithms. A plurality of haptic signal generation units that generates haptic signals using generation algorithms different from each other on the basis of a sound signal by the plurality of haptic signal generation units is included. A mixing unit mixes haptic signals generated by at least two of the plurality of haptic signal generation units to obtain an output haptic signal. For example, a control unit that controls mixing ratios of the mixing unit is further included.
