<P>PROBLEM TO BE SOLVED: To switch listening method between direct transmission of sound information to the skull of a bather and usage of a bathtub itself as a sound producing body. <P>SOLUTION: The vibration of a vibration generator 2 is switched between an advancing position for transmitting the vibration to the bathtub 1 and a retracting position for preventing the transmission of the vibration to the bathtub 1 so as to be freely advanced and retracted. Thus, a usage state at the advancing position for transmitting the vibration to the bathtub 1 makes the bathtub itself into the sound producing body to allow listening of the sound information such as music in the whole of the bathroom. Alternatively, the retracting position for preventing the transmission of the vibration to the bathtub 1 transmits the vibration of the vibration generator 2 from the skull into the brain, when the bather brings the head into contact with a vibration output portion of the vibration generator 2, and stimulates the auditory nerve in the brain through the auditory ossicle/cochlea to produce the sound information in the brain. Therefore, music or the like is allowed to be independently enjoyed under a comfortable usage environment without being affected by various noises in the bathroom. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
