世界上首家使用商业化石英晶振手表的公司是SUWA SEIKOSHA Co.,Ltd.(现称Seiko Epson Corporation).该公司的工程师经过不断的努力,成功的将石英晶体器件小型化,大大的减少了石英晶振产品设备的尺寸.但这项伟大的事迹也许很多人都知道这个事实,但却很少人知道工程师们在背后的战斗.

电子元器件业务的世界是非常残酷的,即使爱普生晶振公司投入了大量的工程师和大量资金来开发尖端技术,即使可以成功的将外部尺寸减半同时又可以提高性能也无法提高价格.实际上除了将尺寸缩小到一半,客户都不愿意接受这个新产品,除非价格可以进一步的降低.这种令人发指的要求放在电子元器件业务上是很正常的.

音叉晶振也是这样,音叉晶体是1969年从世界上第一块石英表”Quartz Astron”中提取开发出来的.并一直在缩小石英晶振的体积从而导致音叉晶振的尺寸越来越小,价格越来越便宜.结果,石英手表以惊人的速度快速扩张.但随着市场的扩大,进入市场的制造商也不断的增加,参与市场的竞争变得越来越激烈.从1975年到1980年这五年之间,音叉式石英晶体谐振器的单价已经降至五分之一.然而SUWA SEIKOSHA(现称精工爱普生SEIKO EPSON)拥有光刻技术,基于这项技术,所以精工爱普生晶振能够以更紧凑及更低成本的方式快速推出市场.从而让精工爱普生晶振奠定了基础.在20世纪80年代早期,精工爱普生晶振已经发展成为一家全球性公司,领导着音叉晶体振荡器行业.

当音叉型水晶振动子遍布全世界,精工爱普生晶振成为世界领先的音叉晶体制造商,不可否认他们已经到达了这种地位,通常情况下,这样的现状可以让整个公司满足下来并安于现状.但是,那些的日本工厂位于长野县石英晶振设备部门的工作人员根本不满足这种情况.原因是他们无法让客户承认精工爱普生晶振是石英晶体设备制造商.虽然现在也已经开始为”精工”品牌手表生产晶振产品,也算是零部件供应商了.精工爱普生晶振极力想得到客户的认可,20世纪70年代中期开始他们开始寻求外销单,开始对外销售石英晶体产品,然后经营规模就变得越来越大,20世纪80年代的前半部分已经大大超过钟表制造商的部分业务.当销售人员拜访客户时,许多人对精工爱普生的评论就是一家手表制造商的石英晶体设备部门.但他们没有气馁,并没有因为客户的评论而丧失信心.而是从那个时候起,石英设备部门的员工们都被点燃了壮志雄心.希望将企业进一步的扩展为一个独立的商业部门.

为什么精工爱普生会没办法被认可是石英晶体设备制造商.尽管他们几乎已经统治了全球的音叉晶体的市场.其实答案很简单,事实上,音叉晶体的市场并不是石英器件的主要竞争领域,主要是AT切割晶体和石英晶体振荡器的市场,他们被用于通信设备.而SUWA SEIKO当时是还没有进入这个市场的.并且在20世纪80年代早期,AT切割晶体单元和晶体振荡的市场需求迅速增长.在那之前AT切割晶体的应用仅限于商业通信设备等.但当数字化浪潮的袭来,使得消费电子设备的需求量倍增,称为个人电脑的全新电子设备市场也在以极快的速度扩张.

物联网是什么？物联网是现代信息技术的重要组成部分,也是"信息化"时代的重要发展阶段.其英文名称是:"Internet of hings（IoT）".实际上,物联网就是物物相连的互联网,其实这里面也是有很多学问的.一,物联网的核心和基础是互联网,在互联网基础上延伸和扩展的网络.二,可延伸和扩展到任何物品与物品之间进行信息交换和通信,物联网可以通过智能感知,识别技术与普适计算等通信感知技术,广泛应用于网络的融合中,所以也被称为继计算机,互联网之后世界信息产业发展的第三次浪潮.是创新应用发展的核心,物联网发展的灵魂.

早期的物联网是依托射频识别(RFID)技术物流网络,意思是通过射频识别(RFID),红外感应器,全球定位系统,激光扫描器,气体感应器等信息传感设备,按约定的协议,把任何物品与互联网连接起来,进行信息交换和通讯.从而来实现智能化识别,定位,跟踪,监控和管理.

物联网用途广泛,智能交通,智能消防,工业监测,环境监测,路灯照明管控等产品,这些电子产品最终都还是没办法离开电子元器件的组成.晶振,智能芯片,定位追踪,射频器等产品.以下列举觉常用的一些IOT用晶振产品型号及参数.
