ABSTRACT:
A timer alarm device is supported on an ear as an earring by pinching an earlobe of the ear with an arm and a clip. Spring force to pinch the earlobe is produced by permitting a spring provided on the clip to run on a corner of a flat part. A timer circuit, a piezoelectric buzzer, and a battery cell, etc., are accomodated on a head part provided on the upper part of the arm. Since the piezoelectric buzzer for outputting an alarm sound is located in the vicinity of an earhole, a user can hear a greater sound even with a smaller sound volume and hence attention of the user can be securely called. Since functions and component parts are limited to eliminate the need of setting and confirmation that rely upon eyes, even a visually handicapped user can conveniently use the device.
