Alarm Clock Movement Introduction
Apr 21, 2017

The clock movement includes two major systems:

1. Walking system: Pointer type quartz electronic alarm clock travel system includes quartz resonator, CMOS IC (Frequency division and drive), stepper motor (power conversion to mechanical energy), counting and transmission mechanism, pointing mechanism and other parts; digital quartz electronic alarm clock travel system includes quartz resonator, CMOS IC (Frequency division, computation and drive), LCD or light-emitting diodes, conductive rubber and other parts; In addition, the pointer and digital type include batteries, trimmer capacitors, Splint and wiring version and other parts.

2. Alarm system: There are two kinds. One is the output signal of an integrated circuit or transistor switching circuit (separating element), driving the speaker or other audible device, and the other is the direct use of electromagnetic principle, through the coil through, the breaking current, the suction hammer percussion hit the alarm bell, or suction other sound devices.
