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.
摘要:
To make it possible to provide an acoustic device in a headrest device such that a standard of a shock is satisfied and the performance of the acoustic device can be efficiently exhibited. In the headrest device, a shock resistant surface is formed in a core material of a headrest main body, an opening is formed in the shock resistant surface, and a non-contact type acoustic microphone is disposed on the inner side of the opening.
