随着社会的发展及科技的进步，移动终端给人们生活带来了极大的便利，人们对移动终端的要求也越来越高。移动终端的听筒作为一个发声器件，需要通过出声孔将声音导出，人们不仅需要移动终端拥有完美的外观，还需要拥有完美的音质。现有技术中，移动终端均是在屏幕上进行挖孔设计，甚至为了减小出音孔，将出音孔开成一个长条窄缝，并将长条的出音孔窄缝设计在手机正面顶端，这种将出音孔面积压缩的技术方案，会相对增加移动终端美观性，但是会引起声阻增大，高频声音成分缺失，导致声音的性能指标不满足要求，还会出现声音小，声音模糊等音质问题，无法同时满足无孔化外观和优质音效两个方面的要求。
如图1、图2和图3所示，本申请提出一种无孔听筒装置,用于移动终端，以朝向移动终端听筒端为移动终端顶部端面，以朝向移动终端喇叭端为移动终端底部端面，包括：听筒本体80，导声通道70和压电晶体20。所述听筒本体80设置在所述移动终端的机壳60上，所述导声通道70设置在所述听筒本体80上，并背离所述机壳60方向延伸，所述压电晶体20与所述听筒本体80分别位于所述导声通道70的两端,所述压电晶体20覆盖在所述导声通道70上，所述压电晶体20电连接所述听筒本体80，并在所述听筒本体80的电极作用下发生形变打开或关闭所述导声通道70。通过上述设置，所述压电晶体20可在所述听筒本体80需要使用时，打开出音孔，导通所述导声通道70，保证播放声音的质量，在所述听筒本体80不需要使用时，关闭出音孔，保证听筒装置的无孔化外观。
上述方案中，通过在所述导声通道70的两端分别设置所述压电晶体20与所述听筒本体80，将所述压电晶体20覆盖在所述导声通道70上；使得所述压电晶体20电连接所述听筒本体80，并在所述听筒本体80的电极作用下发生形变打开或关闭所述导声通道70。能够保证移动终端在非手持通话场景时，屏幕正面没有开孔，外观完整无缺，天然防尘防油污，当处于手持通话场景时，通过控制石英晶体正负极的电压，可以控制石英晶体的压缩量，从而控制开孔的大小，保证通话的声音质量。解决了现有技术中听筒无法同时满足无孔化外观和优质音效的问题。
本申请中使用压电晶体20是一种透明，质地坚硬的晶体材料，具有压电效应和逆压电效应，可被应用于玻璃介质和电子电路。所述的压电效应是指在晶体端面施加压力时，在压力方向上下端面会产生电压。具体的，某些电介质，当沿着一定方向对其施力而使它变形时，其内部就产生极化现象，同时在它的两个表面上产生符号相反的电荷，当外力去掉后，其又重新恢复到不带电状态，这种现象称压电效应。所述逆压电效应是指在晶体端面施加电压信号，晶体会产生压缩或者拉伸的形变，也就是说，当在电介质极方向施加电场，这些电介质也会产生变形，这种现象也称为“电致伸缩效应”。
在本申请具体的实施例中，所述无孔听筒装置包括：控制器，所述控制器一端连接于所述听筒本体80，另一端连接于所述压电晶体20，所述控制器将所述听筒本体80的电信号转换为控制信号。所述控制器用于控制所述压电晶体20的形变，一方面控制在所述听筒本体80需要使用时，所述压电晶体20发生形变打开出音孔，另一方面控制在所述听筒本体80不需要使用时，所述压电晶体20不发生形变闭合出音孔。
在本申请具体的实施例中，所述压电晶体20顶部端面连接于所述控制器的负极，所述压电晶体20底部端面连接于所述控制器的正极，所述控制器根据所述控制信号的电压大小控制所述压电晶体20的形变量。所述控制信号的电压在达到一定的值时，所述压电晶体20才发生形变，并且所述压电晶体20的形变量的大小与电压成正比。
在本申请具体的实施例中，所述压电晶体20的形变量正比于正负电极的电压平方。在一定范围内，增加正负极的电压，可以增大出音孔的开口量，使声音更好的传输。
在本申请具体的实施例中，所述压电晶体20为石英晶体，所述石英晶体是一种透明，质地坚硬的晶体材料，具有时间稳定性、机械性能、电性能、环境适应性强、转换性能等优点。本申请中的所述石英晶体还可以使用压电陶瓷、高分子压电材料等。
在本申请具体的实施例中，所述压电晶体20发生形变量至少为0.4mm。当所述压电晶体20的形变量小于0.4mm时，也就是音孔大小小于0.4mm，会对声音造成很大的衰减，影响声音的品质。
在本申请具体的实施例中，所述听筒本体80包括动圈式听筒。动圈式听筒80能够提供自然舒适的声音听感体验，间距满足各项性能标准。此外，动圈式听筒80使用较简单、牢固可靠、性能稳定、价格相对便宜、噪音低，能承受极高的声压，且几乎不受极端温度或湿度的影响。
对应的，如图4所示，本申请的实施例还提出一种无孔听筒控制方法，包括：
步骤S100、在听筒的导声通道处设置石英晶体，将石英晶体顶部端面连接负极，石英晶体的底部端面连接正极，并控制调整电压信号大小。
为了解决现有技术中，手机听筒无法同时满足无孔化外观和优质音效两个方面的要求。当物理开孔越来越小，开孔小于0.4mm时，会对声音造成很大的衰减，无法进一步减小；当听筒出音孔的物理开孔大小满足声音要求时，会受到尘屑和油污的影响，容易导致堵孔问题。因此，本申请只需要在听筒需要使用时，打开听筒的出音孔，使得听筒的物理开孔大小满足音质要求；在听筒不需要使用时，关闭出音孔，保证听筒不因出音孔的长久开启，进入尘屑或者油污。
具体实施时，本申请所述的移动终端的屏幕设置为玻璃盖板，以朝向移动终端听筒端为移动终端顶部，以朝向移动终端喇叭端为移动终端底部，在听筒的导声通道处设置石英晶体，所述玻璃盖板与所述石英晶体位于同一平面内，将所述石英晶体顶部端面连接负极，所述石英晶体的底部端面连接正极，并通过平台控制调整电压信号大小，以便于所述石英晶体根据电压信号大小进行形变调整。

具体实施时，本申请在移动终端电话接通时，听筒会通电使用，石英晶体的顶部端面接通负极，石英晶体的底部端面接通正极，此时，正负极会加载电压信号，判断正负电极是否加载电压信号，可根据判断的结果控制所述石英晶体的形变。此时，可根据所述石英晶体的正负电极否加载电压信号，控制所述石英晶体的形变，也就是根据听筒是否需要使用的实际状况，控制所述石英晶体是否发生形变。能够保证在需要时，石英晶体发生形变，打开出音孔，不需要时，石英晶体不发生形变，闭合出音孔，可以延长所述石英晶体的使用寿命，从而保证移动终端的寿命。

所述步骤S200判断正负电极是否加载电压信号，根据判断的结果控制所述石英晶体的形变具体包括：

具体的，在所述步骤S211、当所述石英晶体的顶部端面为电场低电势，所述石英晶体的底部端面为高电势时，所述石英晶体产生压缩形变中，控制正负极的电压可以控制晶体压缩的形变量，本质为电压型驱动效应，所述石英晶体的形变量正比于正负电极的电压平方。增加正负极电压，可以加大开孔，使声音更好传输，且这个通电压缩形变过程的电流非常小，整体功耗很低，降低移动终端的电池使用量。
