PROBLEM TO BE SOLVED: To provide a music appreciation chair where only one button operation can increase or decrease the sound volume of its built-in loud speakers and eternal loud speakers at the same time by each nearly identical sound volume level. SOLUTION: In the music appreciation chair 1 provided with the built-in loud speakers 2L, 2R and a remote controller 5 that adjusts the sound volume of the loud speakers, the remote controller 5 comprises a control section 5a including a 1st sound volume adjustment means that adjusts the sound volume of the built-in loud speakers via a conduction wire and a 2nd sound volume adjustment means that adjusts the sound volume of the external speakers 8L, 8R driven by the same sound source 6 as that for the built-in loud speakers by means of light, an operation section provided with an operation button to operate outputs of the 1st and 2nd sound volume adjustment means, and a storage section 5b that stores control data used to adjust the operation of the operation button and the sound volume of the external loud speakers through remote control. The controller 1 transmits the control data to adjust the sound volume of the external loud speakers and the built-in loud speakers nearly at the same time on the basis of the operation of the operation button. |
