如图19所示，本申请实施例提供一种电子设备的控制装置，包括：
检测模块90，用于检测状态信息，所述状态信息包括外部环境的声音、电子设备与人头部之间的相对位置中的至少一个；
控制模块91，用于根据所述状态信息控制第一发声单元10与第二发声单元20发出的声音大小。在使用过程中，通过检测模块90检测状态信息，在嘈杂环境下，可以根据状态信息通过控制模块91控制第一发声单元10的发声音量增大，增强用户通话体验。在安静环境下，可以根据状态信息通过控制模块91控制第二发声单元20的发声音量增大，减小第一发声单元10的声音，从而更好的实现防漏音目的。
在一些实施例中，所述控制模块91用于在外部环境的声音大于第一音量阈值的情况下，控制第一发声单元10发出的声音增大；和/或，控制模块91用于在外部环境的声音小于第二音量阈值的情况下，控制第二发声单元20发
出的声音增大和/或控制第一发声单元10发出的声音减小。
可选地，控制模块91用于在电子设备与人头部之间的相对位置位于第一位置范围的情况下，控制第一发声单元10发出的声音减小；和/或，控制模块91用于在电子设备与人头部之间的相对位置位于第二位置范围的情况下，控制第二发声单元20发出的声音增大。
在应用过程中，如图17a至图17d所示，通话过程中，用户呈现的不同姿势，人脸对声音有反射，造成漏音。理论上，在手机形态的产品上，出声孔的位置设计对于声音传播方向影响不会太大，因人声主要集中在300～3400Hz，波长介于1.13～0.1m之间，其尺寸都远大于手机外形，所以声音基本都会发生衍射，但是基于手机出声孔与人耳的配合不同，每个人握持手机的姿势不同，漏音的大小会有一些区别。如果手机听筒出声孔更靠近顶部，则与人耳耳朵耦合时，不会很严密，漏音会增大。另外，如果在通话过程中，手机与耳朵贴的更紧，也可以一定程度降低漏音。
通过第一发声单元10(比如听筒)和第二发声单元20(比如压电陶瓷)的发声，在不同的场景组合来实现防止漏音。听筒的前音腔可以只发出500hz以下的低频声(可自定义频段，可以通过参数控制)。压电陶瓷可以只发出500hz以上的中高频声(可自定义频段，可以通过参数控制)。泄露孔51处可以发出500hz以下的低频声音，和听筒的前音腔发出的声音相位是反向的。在使用过程中，检测到是否处于嘈杂环境，如果在嘈杂环境下(各种声音混在一起，听筒泄露成分和环境的嘈杂声混合一起不易听清)，则在不泄露声音的前提下，可自动增大第一发声单元10(比如听筒)的发声音量，增强用户通话体验。如果在安静环境下(如果有声音泄露，很容易被附近其他人感知泄露的声音信息)，可以加大第二发声单元20(比如压电陶瓷)的发声音量，减小第一发声单元10(比如听筒)的声音；从而更好的实现防漏音的目的。可以通过检测模块检测周围环境的声音，进而控制加大或减小发声单元的音量。
人头反射的听筒前音腔的低频信号和泄露孔51泄露的低频信号相位刚好相反，可进行抵消，远处几乎听不到低频成分。第二发声单元20可以为压
电陶瓷，推动显示屏发出500Hz以上的中高频信号。由于压电陶瓷贴合到显示屏，在防震结构63的作用下，中高频几乎不会出现泄露的情况。由于第一发声单元10与第二发声单元20两个发声单元的分频功能，以及加上后盖的泄露孔51的作用，可以让低频成分几乎通过相位进行相消除，中高频成分不会出现泄露，从而实现声音信息的防泄露，实现防漏音的目的。
如图18所示，①人耳拾取到的第二发声单元20(比如压电陶瓷)发出的中高频成分的声音(压电陶瓷贴到显示屏40上，在后背上的声音泄露非常小；②人耳拾取到的第一发声单元10(比如听筒)发出的低频成分的声音，综合①与②，用户自己耳朵可以听到全频段的声音，频段不会缺失；③是人脸对第一发声单元10(比如听筒)发出的低频的声音的反射/衍射声音；④是泄露孔51发出的声音(也是低频成分)，和③处声音刚好相位相反；③和④声音相位刚好相反，③与④信号传到A处(其他人)声音相位抵消，A处几乎听不到低频的声音。另外，由于听筒发出的③只有低频成分的声音，A处即使听到声音，也是低频成分，无高频成分，频段缺失导致A处听不清楚具体的内容。①处的中高频声音成分，由于第二发声单元20(比如压电陶瓷)的布局位置以及加上防震泡棉的阻碍，衰减快；①处的中高频成分不能到达A，从而A处听到通话过程中泄露的中高频段的声音成分非常小。通过以上方法，可以实现防漏音的目的，在检测是否嘈杂环境下，对第一发声单元10或第二发声单元20可进行自定义的加减音量。也可以根据用户的使用情况(手持方式、贴近人头与否等)进行自定义发声单元发声情况。第一发声单元10与第二发声单元20可通过不同的组合形态，更好的实现了通话防漏音，保证用户的信息更加安全。该种组合方案可以涵盖的场景多，对比传统的防漏音方案，更加的高效防声音泄露，防漏音效果更佳，用户可以自定义不同发声单元的发声频段，可以通过几套参数进行控制频段，根据嘈杂环境情况，可以对不同发声单元进行声音大小的控制。
