摘要:
To make it possible to improve a low-tone reproducing ability with a simple structure in an acoustic device including speakers in a headrest. The acoustic device includes a core material of a closed structure functioning as a core of a headrest main body, acoustic speakers 50, 50 disposed in the core material, and hollow headrest stays 15, 15 that pierce through the core material. The headrest stays 15, 15 circulate the air on the inside of the core material to the outer side via hollow sections.

There is provided a head rest device 10 that does not impair safety of a seated person even when a secondary battery 35 is accommodated therein. An accommodation space 28 partitioned by a partitioning plate part 25 is provided inside a cushioning core material 12 of a head rest main body, and a secondary battery 35 is accommodated inside the accommodation space 28.
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.
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.
