PROBLEM TO BE SOLVED: To provide comfortable sleep to a user listening to sound by enabling the output of sound extremely faithful to original sound from a comparatively compact speaker unit incorporated in a normal size pillow.SOLUTION: A pillow incorporating a speaker unit S includes: a baffle plate 2 made of thin and flexible soft rubber; and a first cushion body 1 and a second cushion body 3 which have ventilation properties and also rigidity and elasticity enough to support a human head. A frame of the speaker unit S is directly fixed to the baffle plate 2 so as to allow the front surface side of the speaker unit S to face the front surface side of the baffle plate 2. The speaker unit S and the baffle plate 2 are arranged between the first cushion body 1 and the second cushion body 3. Both of the baffle plate 2 and the speaker unit S are held thereby to be freely advanced/retreated in the vibration direction of a diaphragm of the speaker unit S. |
