<p><P>PROBLEM TO BE SOLVED: To provide an oxygen enricher with excellent usability, allowing a user to always use the device comfortably in the relaxed state. <P>SOLUTION: The oxygen enricher comprises an oxygen enriching means 2 for increasing the oxygen concentration in air, a spouting means 7 for supplying the user with oxygen-enriched air, a sucking means 5 for sucking air through the oxygen enriching means 2 and feeding the oxygen-enriched air to the spouting means 7, and a sound output means 24 for outputting sound. The start and/or finish of output of sound from the sound output means 24 is interlocked with the start and/or finish of spouting of the oxygen enriched air from the spouting means 7. As the user can simultaneously listen to the music and effective sound while inhaling the oxygen enriched air in the relaxed state, the user can be made more relaxed than when inhaling the oxygen enriched air only, and the usability is improved. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
