指针式石英电子钟以电池为能源,由石英振荡器产生基准频率,再经分频、放大,并推动步进电机转动,达到计时的目的。 指针式石英电子钟牌号繁多,形状各异,但基本结构相似。“北极星”、“康巴丝”、“东华”、“宝石花”等牌号的石英电子钟在国内占有率较大,质量很好。现在市场 Pointer quartz electronic clock to the battery as the energy source by the quartz oscillator to generate the reference frequency, and then by the frequency, amplification, and to promote the stepper motor rotation, to achieve the purpose of timing. Analog Quartz electronic clock brand variety, different shapes, but the basic structure is similar. Quartz electronic clocks such as “Polaris”, “Compassion”, “Tung Wah Group” and “Precious Stone Flower” occupy a large share in the country and the quality is very good. Now the market
