    摘要： To prevent a person from experiencing discomfort when touching portions of a headrest having built-in speakers; to enable the headrest to be formed compactly by arranging the speakers close to the body of the person; and to prevent any decrease in the acoustic pressure and/or acoustic quality of sound from the speakers. Provided are: a plurality of speakers 25a, 25b; fiber pads 15 provided to the front surfaces of the speakers 25a, 25b; a sound-insulating pad 16 provided between the fiber pads 15; and a surface skin 9 for covering the speakers 25a, 25b, the fiber pads 15, and the sound-insulating pad 16, the fiber pads 15 being formed from an elastic material that has a three-dimensional-mesh structure therein, and the sound-insulating pad 16 being formed from an elastic material for minimizing the transmission of sound.
