ABSTRACT:
A non-acoustic alarm intended to equip a device supplying information such as time information. Such alarm includes motor means (24) which can be electrically driven and which are associated with a mass (26) adapted to be set in motion under the action of the motor means (24) in order to furnish a vibratory effect. Such alarm is furthermore characterized in that the motor means (24) are constituted by an electromagnetic motor (24a, 24b) fixedly mounted on a support (28) including elastic coupling elements (30) which are associated with said mass (26) which is designed to assume a quasi-linear oscillating motion relative to the electromagnetic motor (24a, 24b) when the motor is operated. The invention is particularly adapted for integration within a timepiece.
