    • 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.
    • 用于闹钟等的蜂鸣器机构包括可摆动地支撑在基板上的振动器构件,用于在非活动位置和活动位置之间进行角运动,其中振动器的振动臂面对与交替的驱动线圈相关联的蜂鸣器轭 时钟被振动。 螺旋弹簧将振动器构件压靠在基板上,并将其偏压到主动位置。 振动器构件上的突起接合小时轮,使得当小时轮在时轮上的突起与轴上的孔对准时,时轮被轴向移动时,振动器构件被允许摇摆到主动位置。 报警停止杆可手动操作以使振动器构件返回到非活动位置。
