技术领域
本公开文本实施例涉及通信技术领域，特别是涉及一种基于骨传导扬声器的音频传输方法及移动终端。
背景技术
随着时代的进步，人们越来越重视对个人隐私的保护。在一些特殊场合，比如工作场合办公室，电影院，公交车上等，不方便避开人群时，又有不得不进行的电话交流，只能硬着头皮接听电话。有些场所的环境比较嘈杂导致你不得不提高通话音量，部分隐私便自然“泄露”到了旁人耳中。又或是较为安静的场合，周围少数的人轻松便可窥听到正在接打电话的用户的隐私。
用户使用手机进行通话时，语音以空气为媒介传播于手机和用户之间，这种非定向性的传输在高音量下或者安静的环境中，不可避免地会被周围的人所听到，一些需要保护的保密话题、私密话题无法进行。而且对于鼓膜受损等有听觉障碍但并未完全丧失听觉的人，日常通信无法通过传统的手机进行。
因此，手机通话的安全性和私密性成为一个值得关注的问题。而且，对于听觉障碍人士，日常的通信问题同样也值得关注。

具体实施方式
下面将结合本公开文本实施例中的附图，对本公开文本实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，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，都属于本公开文本保护的范围。
第一实施例
如图1所示，为本公开文本第一实施例的基于骨传导扬声器的音频传输方法的流程图。该方法应用于移动终端。下面就该图具体说明该方法的实施过程。
步骤101，当检测到对所述移动终端中的预设区域的挤压操作时，判断所述挤压操作是否满足预设条件。
这里需要说明的是，移动终端上除设置有音频扬声器外，还设置有骨传 导扬声器。
需要说明的是，挤压操作一般可通过用户的面部或耳朵对移动终端屏幕进行挤压来实现。
步骤102，当所述挤压操作满足预设条件时，通过骨传导扬声器输出音频信号。
需要说明的是，当在移动终端的预设区域未检测到挤压操作或紧压操作未满足预设条件时，通过音频扬声器输出音频信号。
这里，移动终端输出的音频信号可以包括语音、音乐等多种。
这里需要说明的是，当移动终端输出的音频信号通过骨传导扬声器输出时，基于骨传导扬声器的骨传导特性，声波直接以振动的方式通过人面部颧骨传递至耳膜，无需经过外耳和中耳的传输即可转换成“声音”。这样，则可防止用户在使用移动终端通话时，个人隐私的泄露，增强通话的安全性。
本公开文本实施例提供的基于骨传导扬声器的音频传输方法，通过检测到的移动终端中的预设区域的挤压操作，并在该挤压操作满足预设条件时，通过骨传导扬声器输出音频信号，使得用户在高音量下或安静的环境中，使用移动终端进行通话时，可有效避免个人隐私的泄露，增强通话的安全性，提升用户体验。
第二实施例
如图2所示，为本公开文本第二实施例的基于骨传导扬声器的音频传输方法的流程图。该音频传输方法可应用于移动终端。下面就该图具体说明该方法的实施过程。
需要说明的是，本公开文本实施例的方法对应的移动终端，该移动终端的预设区域设置有压电晶体。
更具体的，移动终端的预设区域为所述移动终端的屏幕内表面下的顶角。
这里，压电晶体为压电材料的一种，具有力电耦合性能。也就是，在外力的作用下可发生形变使晶体材料中正负电发生相对位移，因而在一些相对应面上产生极化并形成束缚电荷，可将机械能转换为电能输出。
步骤201，当检测到对所述移动终端中的预设区域的挤压操作时，获取所述压电晶体产生的电信号。
这里，可选的，该压电晶体为钛酸铅压电单晶。
具体的，该压电晶体可靠近移动终端的听筒，位于移动终端的内表面屏幕的顶角位置处。
具体的，如图3所示，本公开文本实施例的步骤201还可具体包括：
步骤2011，检测所述压电晶体是否有电信号产生。
若是，则执行步骤2012；若否，则继续执行该步骤2011，也就是继续检测述压电晶体是否有电信号产生。
这里需要说明的是，若压电晶体有电信号产生，则说明压电晶体受到外力的挤压作用。比如，用户在使用移动终端接听电话时，用户的面部或耳朵挤压压电晶体。
步骤2012，当所述压电晶体产生电信号，对所述电信号进行电荷放大，获取所述电信号对应的电压值。
这里需要说明的是，当压电晶体受外力挤压产生电信号后，该电信号通过电荷放大后送入具有中断唤醒功能的处理器的输入输出接口，通过处理器的检测单元测得该电信号对应的电压值。
这里，具有中断唤醒功能的输入输出接口，起到激活或休眠的作用。也就是，当存在电荷被送入到该输入输出接口时，该输入输出接口被激活，处于工作状态，电荷被传输至处理器中。反之，该输入输出接口则处于休眠状态。这样，移动终端在使用过程中可额外降低耗电量。
步骤202，判断所述电信号的强度是否大于预设阈值；
这里，若所述电信号的强度大于等于预设阈值，则确定所述挤压操作满足预设条件，执行步骤203。否则，若所述电信号的强度小于预设阈值，则确定所述挤压操作不满足预设条件，执行步骤204。
进一步的，步骤202还可具体包括：判断所述电信号对应的电压值是否大于预设阈值；
这里，当所述电信号对应的电压值大于等于预设阈值，则确定所述挤压操作满足预设条件；否则，确定所述挤压操作不满足预设条件。
步骤203，在所述电信号的强度大于等于预设阈值时，通过骨传导扬声器输出音频信号。
这里，预设阈值可理解为移动终端进行骨传导通话的临界值，一般为电压临界值。也就是说，压电晶体上受到的外力到达预设临界值后，才可通过骨传导扬声器输出音频信号，也就是由骨传导扬声器代替原来的音频扬声器工作。
步骤204，在所述电信号的强度小于预设阈值时，通过音频扬声器输出音频信号。
这里，移动终端输出的音频信号可以包括语音、音乐等多种。
本公开文本实施例提供的基于骨传导扬声器的音频传输方法，通过设置在移动终端预设区域的压电晶体，当压电晶体由于外力作用产生的电信号的强度大于预设阈值时，通过骨传导扬声器输出音频信号，使得用户在高音量下或安静的环境中，使用移动终端进行通话时，可有效避免个人隐私的泄露，增强通话的安全性，且切换灵活，提升用户体验。
第三实施例
如图4所示，为本公开文本第三实施例的基于骨传导扬声器的音频传输方法的流程图。该音频传输方法可应用于移动终端。下面就该图具体说明该方法的实施过程。
需要说明的是，本公开文本实施例的方法对应的移动终端设置有骨传导切换功能的使能开关。
步骤301，检测所述使能开关是否开启。
若是，则执行步骤302；若否，执行步骤303。
这里，骨传导切换功能的使能开关的开启或闭合可预先设置，也可在移动终端音频信号的输出过程中设置。
这里，使能开关可以是实际物理开关，也可以是虚拟软件开关。
步骤302，若检测到所述使能开关开启，则通过骨传导扬声器输出音频信号。
这里，移动终端输出的音频信号可以包括语音、音乐等多种。
步骤303，若检测到所述使能开关关闭，通过音频扬声器输出音频信号。
本公开文本实施例提供的基于骨传导扬声器的音频传输方法，通过设置在移动终端上具有骨传导切换功能的使能开关，当检测到该使能开关开启时， 通过骨传导扬声器输出音频信号，使得用户在高音量下或安静的环境中，使用移动终端进行通话时，可有效避免个人隐私的泄露，增强通话的安全性，可提供稳定的骨传导通话环境，提升用户体验。
第四实施例
如图5所示，为本公开文本第四实施例的基于骨传导扬声器的音频传输方法的流程图。该音频传输方法可应用于移动终端。下面就该图具体说明该方法的实施过程。
步骤401，检测所述移动终端是否处于通话状态。
若是，则执行步骤402；反之，则继续执行步骤401。
步骤402，当所述移动终端处于通话状态时，通过骨传导扬声器输出音频信号。
这里需要说明的是，本公开文本实施例只有在移动终端处于通话状态时，才可通过骨传导扬声器输出音频信号，这样可避免非通话状态下的手势操作引起的误切换。
当然，该步骤的前提是，在移动终端处于通话状态，且检测到的移动终端的预设区域的挤压操作满足预设条件和/或移动终端设置的骨传导切换功能的使能开关开启时，可通过骨传导扬声器输出音频信号。
这里，若所述移动终端的屏幕内表面的预设位置设置有压电晶体，其具体通过骨传导扬声器输出音频信号的步骤可详见第二实施例。若所述移动终端设置有骨传导切换功能的使能开关，则通过骨传导扬声器输出音频信号的步骤可详见第三实施例，这里不再赘述。
当然，移动终端上可既在屏幕内表面的预设位置设置有压电晶体，又可设置有骨传导切换功能的使能开关，二者可实现相互配合。
本公开文本实施例提供的基于骨传导扬声器的音频传输方法，通过检测所述移动终端是否处于通话状态，在移动终端处于通话状态时，通过骨传导扬声器输出音频信号，使得用户在高音量下或安静的环境中，使用移动终端进行通话时，可有效避免个人隐私的泄露，增强通话的安全性，且可避免非通话状态下的手势操作引起的误切换，提升用户体验。

第二获取子模块5013，用于对所述电信号进行电荷放大，获取所述电信号对应的电压值。
所述判断子模块5012，具体用于判断所述电信号对应的电压值是否大于预设阈值，如果所述电信号对应的电压值大于等于预设阈值，则确定所述挤压操作满足预设条件；否则，如果所述电信号对应的电压值小于预设阈值，则确定所述挤压操作不满足预设条件。
