SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD
A signal processing device for reproducing a musical piece from one or more loudspeakers and one or more actuators that are provided in a seat includes: an obtainer that obtains data of a plurality of tracks that constitute the musical piece; and an outputter that outputs an acoustic signal included in data of a track among data of the plurality of tracks to the one or more actuators, and outputs an acoustic signal included in data of another track among the plurality of tracks to any loudspeaker among the one or more loudspeakers.
1 . A signal processing device for reproducing a musical piece from one or more loudspeakers and one or more actuators that are provided in a seat, the signal processing device comprising:
an obtainer that obtains data of a plurality of tracks that constitute the musical piece; and
an outputter that outputs an acoustic signal included in data of a track among data of the plurality of tracks to the one or more actuators, and outputs an acoustic signal included in data of another track among the plurality of tracks to any loudspeaker among the one or more loudspeakers.
2 . The signal processing device according to claim 1 , wherein
the outputter:
outputs, to the one or more actuators, an acoustic signal of a kick drum included in data of a drum track among the data of the plurality of tracks; and
outputs, to any loudspeaker among the one or more loudspeakers, an acoustic signal included in data of a track other than the drum track among the plurality of tracks.
3 . The signal processing device according to claim 1 , wherein
the one or more actuators include:
a first actuator provided inside a seating surface of the seat, at a position corresponding to thighs of a person when the person is seated on the seat; or
a second actuator provided inside a seat back of the seat, at a position corresponding to a sacrum of the person when the person is seated on the seat, and
the one or more loudspeakers include:
a first loudspeaker provided inside the seat back of the seat, at a position corresponding to an abdominal region of the person when the person is seated on the seat;
a second loudspeaker provided inside the seat back of the seat, at a position corresponding to a back of the person when the person is seated on the seat;
a third loudspeaker provided inside a headrest of the seat; or
a tweeter attached to the headrest
