在目前的头戴式智能设备以及VR设备中，为了让使用者沉浸在虚拟环境中，其音频输入时经过了降噪处理，并且，其对应的耳机本身也具备已经的降噪功能。也就是说，降噪耳机可以在一定程度上隔绝外界环境的声音，从而避免嘈杂的环境影响耳机的声效体验。
但是，当使用者在使用降噪耳机或者其他降噪设备的过程中，因为降噪耳机本身对环境声音的隔绝，导致了使用者无法及时对周围环境的声音进行反馈。例如，当使用者带着降噪耳机在沙发上听歌的情况下，周围人跟使用者说话；又例如，当周围发生火灾的情况下，使用者因为佩戴降噪耳机而无法察觉或者无法听到火警警报声。
申请人经研究发现，降噪耳机虽然能够隔绝环境噪音对用户在佩戴过程中的噪声影响，但是同时也会隔绝用户需要及时响应的声音。

步骤S304：判断所述目标声音信号是否与预设的环境噪声样本匹配；若否，则执行步骤S306：将所述目标声音信号发送至所述耳机进行播放；若是，则执行步骤S302：检测所述麦克风装置采集的目标声音信号。
如前所述，通过麦克风装置可以实时的对周围环境的声音进行检测，并将检测到的声音转换成对应的电信号，即目标声音信号。
在本实施例中，在判断是否需要将通过麦克风装置采集的目标声音信号发送给耳机进行播放的过程中，是直接判断采集到的目标声音信号与预设的环境噪声样本之间是否是匹配的。也就是说，若目标声音信号与预设的环境噪声样本之间存在一定的匹配度，则说明目标声音信号指示普通的环境噪声，而不是需要去响应的其他声音。
具体的，在目标声音信号与环境噪声样本匹配时，确定需要将目标声音信号输入到耳机进行播放，反之，在目标声音信号与环境噪声样本不匹配时，确定不需要将目标声音信号输入到耳机进行播放。
需要说明的是，在一个可选的实施例中，目标声音信号与环境噪声样本是否是匹配的过程，还可以是计算目标声音信号与环境噪声样本之间的匹配度，也就是说，按照预设的匹配度计算算法，计算目标声音信号与环境噪声样本之间的匹配度，在计算得到的匹配度大于或等于预设的匹配度阈值的情况下，判定所述目标声音信号与环境噪声样本是匹配的，反之，在计算得到的匹配度小于预设的匹配度阈值的情况下，判定所述目标声音信号与环境噪声样本不匹配。
在一个可选的实施例中，环境噪声样本可以是用户预先设置的样本数据，
也就是说，在用户对耳机控制进行设置时，可以通过麦克风装置录制样本数据作为环境噪声样本。
在另一个可选的实施例中，环境噪声样本还是在使用耳机的过程中通过麦克风装置进行采集的，因为在不同的环境下，环境噪声也会不一样，在此种情况下，均使用同一个环境噪声样本可能造成对于目标声音信号的判断不准确。
具体的，在一个实施例中，通过所述麦克风装置采集环境声音信号作为所述预设的环境噪声样本。
例如，在检测到用户开始使用耳机的情况下，发送环境噪声样本录制指令给麦克风装置，由麦克风装置采集环境声音信号，并将采集到的环境声音信号发送给处理器，由处理器将采集到的环境声音信号存储为预设的环境噪声样本，以便在耳机控制的过程中进行比对使用。
进一步的，在另一个实施例中，上述通过所述麦克风装置采集环境声音信号作为所述预设的环境噪声样本还包括：按照预设的时间间隔定期采集通过所述麦克风装置采集环境声音信号，根据该环境声音信号对所述预设的环境噪声样本进行更新。
也就是说，因为随着时间的推移，周围环境的噪声也可能发生改变，在此种情况下，就需要对环境噪声样本也进行同步的更新。具体的，可以根据预设的时间间隔，定期通过麦克风装置采集环境声音信号并对存储的环境噪声样本进行更新。
例如，可以每隔10min采集一次环境声音信号并对环境噪声样本进行更新。又例如，通过与处理器相连的GPS定位装置检测用户的位置信息，在用户的位置信息发生改变时，采集环境声音信号并对环境噪声样本进行更新。
如前所述，在麦克风装置采集到的目标声音信号满足预设条件的情况下，会将采集到的目标声音信号发送给耳机的音频播放模块进行播放。但是，这都只是将声音传递给了用户，用户可能还是不知道周围环境的情况，例如，在用户佩戴了头戴式显示设备的情况下，需要取下佩戴的头戴式显示设备才能进一
步的确定当前周围的环境。
在另一个实施例中，上述耳机控制方法所基于的处理器还连接有显示设备，该显示设备可以用来展示处理器发送的画面，或者其他数据、信息。
在一个可选的实施例中，在所述目标声音信号满足所述预设条件的情况下，在所述预设的显示设备上展示预设的提示信息。
也就是说，在需要让用户听到目标声音信号的情况，不仅将目标声音信号发送到耳机的音频播放装置进行播放，还在显示设备的显示界面上展示预设的提示信息。
在另一个可选的实施例中，展示的提示信息还可以根据目标声音信号的不同而不同。具体的，在目标声音信号的分贝数大于预设的第二分贝阈值的情况下，会直接将目标声音信号发送给耳机进行播放。其中，第二分贝阈值是一个较大的数，例如，90dB而目标声音信号的分贝数大于该值，说明外界环境中存在某些特定的声音，例如，警报声(警报声的分贝数大于90dB)。在此种情况下，可以设置一个与第二分贝阈值对应的提示信息，在目标声音信号的分贝数大于第二分贝阈值的情况下，直接展示该提示信息。
在其他实施例中，还可以设置其他提示信息。例如，在目标声音信号为预设的电话铃声的情况下，提示用户当前有电话接入；又例如，在目标声音信号为预设的人声时，提示用户某人在说话等。
在另一个实施例中，上述耳机控制方法所基于的处理器不仅连接有显示设备，还连接有摄像头，用来采集周围环境的图像或者视频，并且，可以通过上述显示设备进行播放。
具体的，在一个实施例中，所述方法还包括：在所述目标声音信号满足所述预设条件的情况下，通过所述摄像头采集环境图像/视频，在所述预设的显示设备上展示所述采集到的环境图像/视频。
也就是说，在通过麦克风装置采集的目标声音信号是需要发送给耳机进行播放的声音信号的情况下，将目标声音信号发送给耳机进行播放的同时，还将
连接的摄像头采集的环境图像或者环境视频发送给处理器，由处理器发送给显示设备进行播放。
也就是说，在周围环境中存在需要用户进行响应的声音的情况下，不仅将该声音播放给用户，还可以将周围的环境拍摄下来并在对应的显示设备上进行显示，以便用户对当前的环境状况进行分辨。
在另一个可选的实施例中，如图4所示，在用户开始使用降噪耳机的情况下，实时的采集外界的声音信号，并判断实时采集的声音信号是否超过预先采集的环境噪声样本30dB或以上，并且持续时间超过2s、重复出现2次或2次以上，如果均为是，则将采集到的声音信号发送给耳机进行播放。
综上所述，实施本发明实施例，将具有如下有益效果：
采用了上述耳机控制方法以及耳机之后，在使用降噪耳机并隔绝环境噪声的影响的情况下，通过耳机上设置的麦克风装置或者与耳机连接的麦克风装置实时的采集声音信号，然后对采集到的声音信号进行分析和判断，在该声音信号满足预设条件的情况下，将采集到的声音信号发送至耳机进行播放，从而使得用户在使用降噪耳机或者包含了降噪耳机的设备的情况下，也能即时获悉环境中是否存在需要响应的声音，并及时根据通过耳机发送过来的声音做出响应。也就会说，既保证了降噪耳机的正常工作，又可很好的将外界有效的环境声音信号通知至用户，提升了用户体验。
在一个实施例中，如图3所示，图3展示了一种运行上述耳机控制方法的基于冯诺依曼体系的计算机系统的终端。该计算机系统可以是智能手机、平板电脑、掌上电脑、笔记本电脑或个人电脑等终端设备。具体的，可包括通过系统总线连接的外部输入接口1001、处理器1002、存储器1003和输出接口1004。其中，外部输入接口1001可选的可至少包括网络接口10012、麦克风装置10014以及摄像头10016。存储器1003可包括外存储器10032(例如硬盘、光盘或软盘等)和内存储器10034。输出接口1004可至少包括显示屏10042以及音频播放装置10044等设备。
在本实施例中，本方法的运行基于计算机程序，该计算机程序的程序文件存储于前述基于冯诺依曼体系的计算机系统的外存储器10032中，在运行时被加载到内存储器10034中，然后被编译为机器码之后传递至处理器1002中执行，从而使得基于冯诺依曼体系的计算机系统中形成逻辑上的各个虚拟模块。且在上述耳机控制方法执行过程中，输入的参数均通过外部输入接口1001接收，并传递至存储器1003中缓存，然后输入到处理器1002中进行处理，处理的结果数据或缓存于存储器1003中进行后续地处理，或被传递至输出接口1004进行输出。
具体的，所述麦克风装置10014用于采集的目标声音信号；
所述处理器1002用于在所述检测到的目标声音信号满足预设条件时，将所述目标声音信号发送至所述耳机进行播放。
可选的，在一个实施例中，所述处理器1002还用于获取所述目标声音信号的特征信息，判断所述特征信息是否与预设的特征参考值匹配，若是，则判定所述目标声音信号满足所述预设条件。
可选的，在一个实施例中，所述麦克风装置10014还用于采集环境声音信号作为所述预设的环境噪声样本。

于展示摄像头10016采集到的环境图像/视频。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
