ABSTRACT:
A buzzer mechanism for an alarm clock or the like comprises a vibrator member rockably supported on a base plate for angular movement between an inactive position and an active position in which a vibration arm of the vibrator faces a buzzer yoke associated with the alternating driving coil of the clock so as to be vibrated. A coil spring presses the vibrator member against the base plate and also biases it toward active position. A projection on the vibrator member engages the hour wheel so that when the hour wheel is moved axially upon a projection on the hour wheel coming into registry with a hole in an unlocking drum, the vibrator member is permitted to rock to active position. An alarm stop lever is operable manually to return the vibrator member to inactive position.
