Title:
VIBRATION-DETECTING DEVICE AND TOILET SEAT
Document Type and Number:
WIPO Patent Application WO/2004/112600
Kind Code:
A1
Abstract:
A vibration-detecting device for highly accurately detecting vibration transmitted to a rigid body, and particularly a toilet seat device for highly accurately detecting user’s body movement transmitted to a toile seat. A vibration-detecting device has pressing means (amplifying means) (27) for amplifying vibration caused by a user’s body movement transmitted to an upper lid (rigid body) (6) of a toilet seat device (5) and has a piezoelectric sensor (vibration-detecting sensor) (9) for detecting the amplified vibration. With this structure, the user’s body movement transmitted to a toilet seat is detected by the piezoelectric sensor (vibration-detecting sensor) after being amplified by the pressing means (amplifying means)(27). As a consequence, even if the toilet seat has almost no deformation by the user’s body movement transmitted to the toilet seat, the body movement can be detected with excellent accuracy.
