贴片晶振通常应用于智能电子设备场合,他是一款小型的石英晶振元件,具有薄型、高精度等特点。晶振在智能手表手环中的作用是通过传感器给智能手环接提供信号频率,是很重要的核心部位,其中32.768Khz频率贴片晶振在其中扮演着非常重要的角色。

随着晶振技术的成熟,可穿戴养老技术设备的研发机构如雨后春笋般越来越多。研发机构由最初的几家国际互联网迅速蔓延至国内的中小企业,这种发展势头刺激了钟表行业,让传统的传统钟表行业开始思考,纷纷转型升级加入到智能手表研发生产行列。我们熟知的品牌如苹果,微软,小米和华为等各大品牌都紧跟着消费者的需求推出了它们的智能手表。智能手表除了具有时间,通话功能以外,还具有定位, 检测我们的心率等智能化功能。那么我们的智能手表和普通手表中使用的晶振一样吗?

首先,大家都知道晶振是一种频率元件,其主要作用是接受命令及传递信号,只要与时间有关的都会用到我们的32.768K晶振,而32.768K晶振分为插件晶振和贴片晶振。圆柱晶振常见于我们戴的普通手表中,而32.768K贴片晶振可以让智能手表实现GPS导航等功能。智能手表的内部比石英电子表更加精密复杂,其中的功能模块有LED驱动器,触摸屏控制器,蓝牙模块等等。智能手表中所使用的晶振也不仅限于32.768KHZ频率,其石英晶体振荡器以及石英晶振更能满足智能手表对精度和稳定性的需求。

一般智能手表所需的是石英晶振或者陶瓷晶振,为了满足一些特殊功能,也会采用一些耐高温的贴片晶振,温补晶振及恒温晶振等等,晶振同智能手表的其他配件互相配合,为用户提供更智能的功能与服务。高端的智能手表可以选择2x6插件晶振。晶振为智能手表提供了稳定的震荡电路,使智能手表有了更多样化的发展.

智能产品的变革对晶振行业带来的影响-传统手表中使用的是32.768KHZ晶体,然而智能手表中使用的是超小超薄型贴片晶振看似成熟的智能手表后续功能仍需晶振的支撑-智能手表的功能一直在不断的更新改革,看似成熟的市场,其实还有很多功能需要去体现研发出来。
