AIR-FEEDING APPARATUS, AND CLOSED-SPACE ROOM AND AUDIO EQUIPMENT PROVIDED WITH THE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an air-feeding apparatus with which a relaxing effect and an effect on fatigue reduction can be expected by obtaining high concentration oxygen by atmospheric sound automatically.

SOLUTION: The apparatus is provided with: an air-feeding part 2 which varies oxygen concentration; an analysis part 3 for analyzing the atmospheric sound: and a control part 4 for commanding the oxygen concentration to be fed from the air-feeding part 2. Thus, when stimulation of the sound is received, air having an oxygen concentration which relaxes the stimulation with respect to the sound is fed automatically without operation for feeding the high concentration oxygen. Thus, the relaxing effect and the effect on fatigue reduction can be expected.
