技术领域
本公开涉及通信技术领域，尤其涉及一种移动终端。
背景技术
随着移动终端的迅速发展，移动终端已经成为人们生活中必不可少的一种工具，为用户生活的各个方面带来了极大的便捷。由于移动终端的存在，使用户与用户之间的沟通更加方便。用户在使用移动终端与其他用户进行通话时，当自己身边存在一些用户，通话的内容比较容易被身边的用户听到，从而容易导致用户隐私的泄露。
发明内容
本公开实施例提供一种移动终端，以解决移动终端通话过程中，容易导致用户隐私的泄露的问题。
为了解决上述技术问题，本公开是这样实现的：一种移动终端，包括第一受话器和第二受话器；所述移动终端相对的两侧开设有第一腔体和第二腔体，所述第一腔体设有第一开口，所述第二腔体设有第二开口，所述第一开口与所述第二开口的朝向相反，且均与外界连通，所述第一受话器设置于所述第一腔体内，所述第二受话器设置于所述第二腔体内，所述第一受话器输出第一声音信号，所述第二受话器输出第二声音信号，所述第一声音信号与所述第二声音信号的相位相反。
本公开实施例的一种移动终端，包括第一受话器和第二受话器；所述移动终端相对的两侧开设有第一腔体和第二腔体，所述第一腔体设有第一开口，所述第二腔体设有第二开口，所述第一开口与所述第二开口的朝向相反，且 均与外界连通，所述第一受话器设置于所述第一腔体内，所述第二受话器设置于所述第二腔体内，所述第一受话器输出第一声音信号，所述第二受话器输出第二声音信号，所述第一声音信号与所述第二声音信号的相位相反。这样，由于第一声音信号与第二声音信号相位相反，从而第一声音信号和第二声音信号可以相互抵消，从而避免了通话内容的泄露，很好的保护了用户的隐私。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是本公开实施例提供的移动终端的结构图；
图2是本公开实施例提供的声音信号传播的示意图；
图3是本公开实施例提供的电路连接示意图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的移动终端的结构图，如图1所示，移动终端包括第一受话器1和第二受话器2；所述移动终端相对的两侧开设有第一腔体3和第二腔体4，所述第一腔体3设有第一开口，所述第二腔体4设有第二开口，所述第一开口与所述第二开口的朝向相反，且均与外界连通，所述第一受话器1设置于所述第一腔体3内，所述第二受话器2设置于所述第二腔体4内，所述第一受话器1输出第一声音信号，所述第二受话器2输出第二声音信号，所述第一声音信号与所述第二声音信号的相位相反。
本实施例中，移动终端还可以存在电池5。上述移动终端的两侧，可以 是屏幕和背面的壳体，或者也可以是移动终端边缘相对的两侧。可选的，移动终端的两侧中，一侧可以为屏幕，另一侧可以为背面的壳体。上述第一受话器1输出第一声音信号，第二受话器2输出第二声音信号，第一声音信号与第二声音信号的相位相反，则可以相互抵消，从而避免了通话内容的泄露，很好的保护了用户的隐私。
为了更好的理解上述过程，请参阅图2，图2为本公开实施例提供的一种声音信号传播的示意图。图2中，A为移动终端上靠近用户耳朵的受话器，可以记为受话器A；B为移动终端上远离用户耳朵的受话器，可以记为受话器B。a为受话器A发出的声音信号的传播路径，b为受话器B发出的声音信号的传播路径，C为移动终端的使用用户身边的其他用户。
这样，当移动终端的使用用户在进行通话时，受话器A发出的声音信号一部分被该用户的耳朵接收，剩下的一部分经过该用户头部反射从而到达移动终端的背面，即图2中C的位置，且声音信号的传播路径为a。受话器B发出的声音信号直接向周围辐射，也可以到达C处。
受话器A可以为移动终端屏幕上的受话器，受话器B可以为移动终端背面壳体上的受话器。一般来说，C与受话器A之间的距离，以及C与受话器B之间的距离均大于1米。受话器A与受话器B之间的距离(可以看作移动终端的厚度)一般为1厘米。受话器的共振频率f 0：当受话器系统(可以包括受话器腔体)受激励的频率与该系统的固有频率相接近时系统振幅达到最大。受话器腔体的f 0在400赫兹左右，此处振幅最大，消除f 0附近频率的声音可以比较好的消除漏音。
由于λ＝v/f，声音在空气中的传播速度v取340米/秒，f取f 0即400赫兹，则计算得到f 0处声音信号的波长为0.85米，而传播路径差值a-b远小于0.85米，从而可以忽略此处造成的影响，即声音信号的传播路径未产生相位差，所以需要受话器A和受话器B之间输出的声音信号的相位相反，才可以将声音信号抵消。
由于受话器离移动终端的使用用户的耳朵之间的距离很近，且移动终端的受话器A与受话器B之间的距离也很近，从而近似可以忽略上述距离的影响。由于受话器A与受话器B输出的声音信号的相位相反，即受话器A与受 话器B输出的声音信号的位相差1/2波长的奇数倍，声音会相互抵消，移动终端周围的用户C则听不到通话的内容，很好的保护了用户的隐私。
本公开实施例中，上述移动终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等等。
可选的，所述第一受话器1和所述第二受话器2均与所述移动终端的音频输出电路电连接，且所述音频输出电路向所述第一受话器1输出的声音信号，与向所述第二受话器2输出的声音信号的相位相反。
本实施方式中，上述第一受话器1和所述第二受话器2均与所述移动终端的音频输出电路电连接，从而音频输出电路可以将声音信号输出到第一受话器1和第二受话器2。上述音频输出电路向所述第一受话器1输出的声音信号，与向所述第二受话器2输出的声音信号的相位相反，可以通过一个音频解码器来实现，或者也可以通过两个甚至多个音频解码器来实现，对此本实施方式不作限定。通过音频输出电路向不同的受话器输出相位相反的声音信号，从而可以使声音信号相互抵消，避免漏音。
可选的，所述音频输出电路包括音频解码器。
本实施方式中，上述音频输出电路包括音频解码器，从而可以很好的对声音信号进行解码，从而输出到不同的受话器。
可选的，所述第一受话器1的正输入端和所述第二受话器2的负输入端，均与所述音频解码器的正输出端连接；所述第一受话器1的负输入端和所述第二受话器2的正输入端，均与所述音频解码器的负输出端连接。
本实施方式中，上述第一受话器1的正输入端和所述第二受话器2的负输入端，均与所述音频解码器的正输出端连接；上述第一受话器1的负输入端和所述第二受话器2的正输入端，均与所述音频解码器的负输出端连接。这样可以使第一受话器1和第二受话器2接收到相位相反的声音信号，从而各自输出相位相反的声音信号，以使声音信号进行抵消。
为了更好的理解上述连接方式，请参阅图3，图3为本公开实施例提供的一种电路连接示意图。图3中可以看到，音频解码器和受话器均存在P端 和N端，音频解码器的P端和N端分别为正输出端和负输出端，受话器的P端和N端分别为正输入端和负输入端。音频解码器的P端与第一受话器的P端和第二受话器的N端连接，音频解码器的N端与第一受话器的N端和第二受话器的P端连接。从而，第一受话器和第二受话器可以接收相位相反的声音信号，从而输出相位相反的声音信号。
相关技术中，需要使用相位消除泄露的声音需要增加语音信号相位检测模块和反相语音信号生成模块，且检测和生成过程存在时间延迟，不能很好地消除泄露的声音。本实施方式中，只需要一个音频解码器就可以向两个受话器输出相位相反的声音信号，既保证了时间上的同步，也节省了移动终端的成本。
可选的，所述第一受话器1设置于所述移动终端的显示屏所在的一侧，所述第二受话器2设置于所述移动终端的背面壳体所在的一侧。
本实施方式中，上述第一受话器1设置于所述移动终端的显示屏所在的一侧，所述第二受话器2设置于所述移动终端的背面壳体所在的一侧。当用户使用第一受话器1接听来电时，第一受话器1输出的第一声音信号经用户头部反射可以与第二受话器2输出的第二声音信号相互抵消，从而使壳体朝向的一些用户听不到移动终端的使用用户的接听内容，从而很好的保护了用户的隐私。
当然，随着移动终端技术的迅速发展，可能出现两侧均为显示屏的移动终端。例如，移动终端的一侧为第一显示屏，另一侧为第二显示屏。此时，也可以采用本实施方式的设置方式设置受话器，例如，可以将第一受话器1设置于第一显示屏所在的一侧，将第二受话器2设置于第二显示屏所在的一侧。这样，在用户通话时，亦可以很好的保护用户的隐私。
可选的，所述第一受话器1与所述第二受话器2正对设置。
本实施方式中，上述第一受话器1与所述第二受话器2正对设置，从而使第一受话器1和第二受话器2之间的距离达到最小，从而可以将误差减小到最小，更好的消除漏音。
可选的，所述第一受话器1的轴心线与所述第二受话器2的轴心线不在同一条直线上。
本实施方式中，移动终端上可能存在一些其他的部件，例如一些传感器或者一些摄像头等等，这样第一受话器1和第二受话器2可能无法做到正对设置，此时就可以存在一些偏差。使第一受话器1的轴心线与第二受话器2的轴心线不在同一条直线上，从而可以很好的避开移动终端上其他的一些部件。
可选的，第一受话器1包括第一振膜11和第一出音孔12，所述第二受话器2包括第二振膜21和第二出音孔22。
本实施方式中，上述第一振膜11可以产生振动，发出的声音信号可以经过第一出音孔12。同理，第二受话器2亦可以以同样的原理进行发声。
可选的，所述第一受话器1与所述第二受话器2的规格相同。
本实施方式中，上述规格可以包括体积、长度、形状和重量等等。上述第一受话器1与所述第二受话器2的规格相同，从而可以使第一受话器1输出第一声音信号和第二受话器2输出第二声音信号更好的抵消，从而消除漏音。
可选的，所述第一腔体3与所述第二腔体4的大小相同。
本实施方式中，上述第一腔体3与所述第二腔体4的大小相同，使移动终端的结构对称，亦能使第一声音信号和第二声音信号更好的抵消，从而消除漏音。
本公开实施例的一种移动终端，包括第一受话器1和第二受话器2；所述移动终端相对的两侧开设有第一腔体3和第二腔体4，所述第一腔体3设有第一开口，所述第二腔体4设有第二开口，所述第一开口与所述第二开口的朝向相反，且均与外界连通，所述第一受话器1设置于所述第一腔体3内，所述第二受话器2设置于所述第二腔体4内，所述第一受话器1输出第一声音信号，所述第二受话器2输出第二声音信号，所述第一声音信号与所述第二声音信号的相位相反。这样，由于第一声音信号与第二声音信号相位相反，从而第一声音信号和第二声音信号可以相互抵消，从而避免了通话内容的泄露，很好的保护了用户的隐私。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者 装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
