Description

一种电器元件及移动终端 本申请基于申请号为 201210390085.X、 申请日为 2012年 10月 15日的中国专利申请 提出， 并要求该中国专利申请的优先权， 该中国专利申请的全部内容在此引入本申请作为 参考。 技术领域
本公开涉及一种移动终端结构， 特别涉及一种电器元件及移动终端。 背景技术
ESD (Electro-Static discharge)的意思是"静电释放"， 静电产生的原因有很多种， 包括 接触、 分离或相互摩擦等。 静电具有长时间积聚、 高电压、 低电量、 小电流和作用时间短 的特点。静电在我们的日常生活中可以说是无处不在， 我们的身上和周围就带有很高的静 电电压，几千伏甚至几万伏。这些静电也许对人体影响不大，但对于一些对静电敏感的电器 元件， 却直接可以使其失去本身应有的正常性能， 甚至完全丧失正常功能。 由于我们常用 的大多数移动终端 （例如手机、 平板电脑） 中， 存在很多这类电器元件， 所以在设计制造 时， ESD防护就非常重要。
出于静电防护的考虑， 移动终端的出音孔的防尘网一般都采用非金属材质， 用以隔绝 静电的放电路径， 但是非金属材质的硬度不够， 容易塌陷、 变形， 造成外观不良。
而现在的智能手机基本上都配备有接近传感器，其主要功能是能够在通话时检测到人 体接近手机， 从而关闭屏幕省电。 接近传感器的位置一般和听筒紧邻， 因此当为了加强硬 度而必须采用金属材质的出音孔防尘网时， 接近传感器的静电防护就成为一个难题， 尤其 是结构不能大幅度改动的情况下， 更是困难。 发明内容

本实例中， 所述参考电平线可以是地线， 这样， 当静电敏感元件周围的听筒结构有静 电释放时， 该静电防护电路可以将听筒结构释放的静电释放到地上， 以保证静电敏感元件 可以正常工作。
本实例中， 所述静电防护电路由一或多个静电防护器件连接构成， 其中， 所述静电防 护器件可为瞬变抑制二极管 TVS, 压敏电阻等等。
需要说明的是，上述实施例中所述的设置绝缘体和静电防护电路的技术手段在需要的 情况下可以单独采用或同时采同， 这三种情况都可以达到静电防护的效果。本公开移动终 端不需要大幅度改变结构， 简单易行， 适用于绝大多数移动终端， 例如 PDA、 平板电脑、 手机等， 可以大规模量产， 通过有效的防护 ESD改善了用户体验。
本实例中， 当静电防护装置 3包括静电防护电路和绝缘体时， 静电防护装置 3与静电 敏感元件 2 相连的方式可以为： 所述绝缘体设置在所述静电敏感元件与所述听筒结构之 间， 所述静电防护电路的输入端至少与所述静电敏感元件的一个管脚相连， 输出端与所述 移动终端内预设的参考电平线相连， 所述静电防护电路在所述听筒结构释放静电时， 对所 述静电敏感元件进行静电保护。
当静电防护装置 3包括静电防护电路和绝缘体时， 静电防护装置 3与静电敏感元件 2 相连的方式可以为： 所述绝缘体粘合在所述静电敏感元件的外缘， 所述静电防护电路的输 入端至少与粘合有所述绝缘体的静电敏感元件的一个管脚相连，输出端与所述移动终端内 预设的参考电平线相连， 所述静电防护电路在所述听筒结构释放静电时， 对所述静电敏感 元件进行静电保护。
当静电防护电路和绝缘体同时使用时， 如果静电敏感元件周围有静电释放， 该绝缘物 体就可以将静电敏感元件周围释放的静电隔绝， 当不能完全隔绝静电时， 静电防护电路还 可以将未隔绝的静电释放到某处 （如地上） ， 对静电敏感元件达到双重静电防护的目的。
上述静电敏感元件可包括传感器和 \或红外 LED指示灯，所述传感器可为接近传感器、 温度传感器等等现有技术下常用传感器。
如图 4所示， 例如， 所述听筒结构包括： 听筒主体 1.1、 挡板 1.2及金属防尘网 1.3; 所述听筒主体外围两侧或四周设置有所述挡板，所述听筒主体下方及所述挡板底部处 设置有所述金属防尘网， 所述听筒主体、 所述挡板及所述金属防尘网围成一出音孔。 由于 本公开上述实施例中采取的了设置绝缘体和 /或静电防护电路的措施， 所以本移动终端的 防尘网可以为金属防尘网 1.3。 设置金属防尘网有助于增强听筒结构的硬度， 不易塌陷， 外观美观。
图 5所示，移动终端中设有的挡板 1.2—般不能完全围住听筒主体 1.1，尤其是不能挡 住防尘网 1.3， 而且在高度上也不符合静电防护的需要， 一般地， 所述听筒主体在高度方 向上由下自上依次为金属层 1.1.1和听筒 1.1.2。
而本公开如图 6所示， 挡板 1.2将所述听筒主体全部围住， 尤其将金属防尘网 1.3也 同时围住， 并在高度上大于所述听筒主体的高度， 使所述听筒主体与电器元件之间的空气 放电路径增大， 由于通过空气传播则静电的能量衰落很快， 因此空气放电路径越长， 越有 利与 ESD 防护， 而通过金属传播的静电则由挡板隔绝， 所述绝缘层对经过衰减的静电进 行隔绝。
上述设置挡板的方式可为多种， 例如：
实施例一
所述听筒主体外围两侧设置有所述挡板，所述听筒主体下方及所述挡板底部处设置有 所述金属防尘网的设置方式可以为：
所述听筒主体及所述金属防尘网由上至下置于所述两侧挡板间，且所述听筒主体与所 述金属防尘网之间存在预定尺寸的空间， 以使所述挡板加长所述听筒结构在释放静电时的 放电路径， 对所述电器元件进行静电防护。
实施例二
所述听筒主体外围四周设置有所述挡板，所述听筒主体下方及所述挡板底部处设置有 所述金属防尘网的设置方式可以为：
所述听筒主体及所述金属防尘网由上至下置于所述四周挡板所围成的空间内，且所述 听筒主体与所述金属防尘网之间存在预定尺寸的空间， 以使所述挡板加长所述听筒结构在 释放静电时的放电路径， 对所述电器元件进行静电防护。
实施例三
所述挡板包括中空底座与环形凸台， 所述环形凸台设置在所述中空底座上； 相应地， 所述听筒主体外围两侧设置有所述挡板， 所述听筒主体下方及所述挡板底部 处设置有所述金属防尘网的设置方式可以为：
所述听筒主体位于两个挡板的环形凸台之间，且所述环形凸台的高度高于所述听筒主 体的高度， 所述金属防尘网位于两个挡板的中空底座之间， 且所述中空底座的下缘遮挡住 所述金属防尘网， 以使所述挡板加长所述听筒结构在释放静电时的放电路径， 对所述电器 元件进行静电防护。
实施例四
所述挡板包括中空底座与环形凸台， 所述环形凸台设置在所述中空底座上； 相应地， 所述听筒主体外围四周设置有所述挡板， 所述听筒主体下方及所述挡板底部 处设置有所述金属防尘网的设置方式可以为：
所述听筒主体位于四周挡板的环形凸台之间，且所述环形凸台的高度高于所述听筒主 体的高度， 所述金属防尘网位于四周挡板的中空底座之间， 且所述中空底座的下缘遮挡住 所述金属防尘网， 以使所述挡板加长所述听筒结构在释放静电时的放电路径， 对所述电器 元件进行静电防护。
在实施例三与实施例四中， 如图 6所示， 在所述中空底座 1.2.2上的环形凸台 1.2.1的 高度决定了所述挡板的隔绝性能。 可以理解的是， 环形凸台的高度不一定必须一致， 可以 只加高旁边设有电器元件的一侧高度， 对不设有电器元件的侧边不加高， 以节省材料。
可以理解的是， 上述实施例仅为本公开的几种实施例， 所述挡板的高度可以不大于所 述听筒主体的高度， 也可以不完全围住全部所述听筒主体， 只使用绝缘层或致采用静电防 护电路一样可以达到较好的静电防护效果。
所述挡板根据需要还可设置为其它形式， 需要注意的是， 可以使所述挡板的高度大于 所述听筒主体的高度， 所述挡板的材料可以为绝缘材料。
综上所述， 本公开实施例， 通过在听筒结构和静电敏感元件之间设置绝缘体和 /或在 静电敏感元件的一个管脚设置静电防护电路，从而实现了对移动终端内电器元件的静电防 护， 使移动终端能够正常工作， 保证了用户体验； 使挡板能够完全围住听筒主体并且高于 听筒主体， 较好的对听筒主体发出的静电进行衰减和隔离。 另外本公开移动终端由于不需 要对移动终端本身的结构进行大的更改， 简单易行， 适合大规模的工业化量产。
另外， 本实例在实现时为了达到对静电敏感元件进行进行静电保护的目的， 基于上述 技术方案的思想， 还可以对终端设备 （如手机等移动终端） 内释放静电的装置（如手机内 的听筒结构）进行改进， 可以为： 在释放静电的装置的外缘粘合以上所述的绝缘胶， 使得 该绝缘胶可以隔绝该释放静电的装置所释放的静电，从而对置于该释放静电的装置周围的 静电敏感元件 （如上所述的接近传感等）进行静电保护； 或者， 在实现时， 在释放静电的 装置中设置一如上所述的静电防护电路，使得该静电防护电路可以将释放静电的装置所释 放的静电释放到地上， 以对该释放静电的装置周围的静电敏感元件进行静电保护。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和 范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内， 则本公开也意图包含这些改动和变型在内。
