Annunciating device, e.g. for automobile, has vibration generators at interior part of seat to generate vibration by reciprocating vibrator, which reciprocates on axis line that does not intersect with support frame

摘要

The device has a pair of support frames at both sides of a seat (1) and extending in a back and forth direction or in an up and down direction of the seat. Two vibration generators (10) are provided side by side at an interior part of the seat for generating a vibration by reciprocating a vibrator. The vibrator reciprocates on an axis line, which does not intersect with the support frame. The vibration generator and the pair of support frames are provided at a seating portion (2) of the seat. An independent claim is also included for an alerting device including an annunciating device.
