Description

一种耳机声道控制方法、相关设备及系统 技术领域
本发明实施例涉及通信技术领域，具体涉及一种耳机声道控制方法、相关设备及系统。
背景技术
现在的耳机一般具有左声道与右声道之分，且大部分耳机都是固定声道输出，例如，耳机左听筒输出左声道，耳机右听筒输出右声道。用户在使用耳机欣赏音乐和观看视频时，为了得到较好的听觉体验，一般会将耳机左听筒佩戴于左耳，耳机右听筒佩戴于右耳。一旦耳机左右听筒戴反了，可能就会出现用户观看到的视频画面是左边的演员正在讲话，而用户的右耳听到的声音比却左耳听到的声音稍微强些的情况，从而影响了听觉效果。在这种情况下，用户一般是通过对调耳机听筒的佩戴位置来进行声道切换，但这种切换方式效率较低。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种耳机声道控制方法、相关设备及系统，能够提高耳机声道的切换效率。以下分别进行详细说明。
为了更好的理解本发明实施例公开的一种耳机声道控制方法、相关设备及系统，下面先对本发明实施例适用的场景进行描述。请参阅图1，图1是本发明实施例公开的一种耳机声道控制的场景示意图。在图1所示的场景中，包括耳机和终端，其中，所述耳机为立体声耳机，具有左声道和右声道之分，所述耳机可以包括无线耳机(如蓝牙耳机)和有线耳机(即具备3.5mm耳机接口的耳机，包括头戴式耳机、耳塞式耳机、挂耳式耳机等)，那么所述耳机可以通过3.5mm耳机接口与终端建立通信连接，也可以通过蓝牙与终端建立通信连接，本发明实施例不做限定。所述终端可以包括但不限于智能手机(如Android手机、iOS手机等)、平板电脑、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、移动互联网设备(Mobile Internet Device，MID)以及智能穿戴设备等可以与耳机建立通信连接的终端。
在耳机与终端建立通信连接的情况下，如果终端正在进行通话、播放音乐、视频、启动游戏等，那么终端就会将音频信号通过耳机输出，且用户通过耳机听到的声音具有立体感。
基于图1所示的场景，本发明实施例公开了一种耳机声道控制方法。请参阅图2，图2是本发明实施例公开的一种耳机声道控制方法的流程示意图。其中，图2所描述的方法可以应用于耳机声道控制系统，所述系统包括终端和预先与所述终端建立有通信连接的耳机。如图2所示，所述耳机声道控制方法可以包括以下步骤：
201、耳机确定所述耳机的佩戴模式。
本发明实施例中，耳机与终端建立通信连接。所述耳机与所述终端可以通过以下两种方式建立通信连接：一种为有线连接，即将耳机接口插入终端的耳机插孔，另一种为无线连接，即耳机与终端通过蓝牙建立连接。所述耳机与所述终端建立通信连接后，所述耳机可以确定所述耳机的佩戴模式，其中，所述佩戴模式包括耳机戴反模式和耳机佩戴正确模式。
具体的，请一并参阅图3，图3是本发明实施例公开的确定耳机的佩戴模式的场景示意图。所述耳机左右听筒的相对位置分别设置有距离传感器(如图3所示的距离传感器的位置)，所述距离传感器具体是在左右听筒相对放置时的相同侧设置。如果用户正确佩戴耳机(即将耳机左听筒佩戴于用户的左耳，耳机右听筒佩戴于用户的右耳)，那么两个听筒的距离传感器检测到的距离就会比较大(即距离传感器检测到的距离在大于某一距离阈值的指定距离范围内)，所述耳机的佩戴模式即为耳机佩戴正确模式；如果用户将耳机戴反，那么距离传感器检测到的距离(即距离传感器与耳廓之间的距离)就会比较小，所述耳机的佩戴模式即为耳机戴反模式。当然，距离传感器也可以同时设置在左右听筒的另一侧，如果用户正确佩戴耳机，那么两个听筒的距离传感器检测到的距离就会比较小(即距离传感器检测到的距离在小于某一距离阈值的指定距离范围内)；如果用户将耳机戴反，那么两个听筒的距离传感器检测到的距离(即距离传感器与耳廓之间的距离)就会比较大，通过这种方式从而可以确定用户是否将耳机戴反。
具体实现中，耳机确定所述耳机的佩戴模式的主要方式可以包括以下步骤：
11)所述耳机检测与障碍物的距离，并判断所述距离是否在预设距离阈值内；
12)在所述距离不在所述预设距离阈值内时，确定所述耳机的佩戴模式为耳机戴反模式；
13)在所述距离在所述预设距离阈值内时，确定所述耳机的佩戴模式为耳机佩戴正确模式。
本发明实施例中，所述耳机主要通过耳机左右听到配置的距离传感器来检测与障碍物之间的距离，从而获取该距离，并判断所述距离是否在预设距离阈值内，以此来确定所述耳机的佩戴模式。
需要说明的是，所述耳机可以是获取耳机左听筒的距离传感器检测到的距离，也可以是获取耳机右听筒的距离传感器检测到的距离，还可以是同时获取两听筒的距离传感器检测到的距离，本发明实施例不做限定。所述预设距离阈值可以理解为：如果距离传感器设置在耳机听筒在正确佩戴时靠近用户耳朵的一侧，那么所述预设距离阈值即为小于某一距离阈值的距离范围，如小于1厘米；如果距离传感器设置在耳机听筒在正确佩戴时远离用户耳朵的一侧，那么所述预设距离阈值即为大于某一距离阈值的距离范围，如大于3厘米。
本发明实施例中，耳机可以判断任意耳机听筒设置的距离传感器检测到的距离是否在预设距离阈值内，也可以判断耳机左右听筒的距离传感器检测到的距离是否均在预设距离阈值内。
因此，当所述距离不在预设距离阈值内时，耳机就可以确定所述耳机戴反，当所述距离在所述预设距离阈值内时，就可以确定所述耳机佩戴正确。
在上述方式中，所述耳机还可以先确定所述耳机是否处于佩戴状态，在所述耳机处于佩戴状态后，再检测所述耳机与障碍物之间的距离。
需要说明的是，所述耳机确定所述耳机是否处于佩戴状态的具体方式可以为：所述耳机设置有在用户佩戴耳机的状态下外部声音不经过遮挡物而被获取的外侧麦克风和在用户佩戴耳机的状态下外部声音经由遮挡物被获取的内侧麦克风，这样内侧麦克风和外侧麦克风就可以实时检测环境中的声音信号，并 对获取的声音信号进行比较。如果内侧麦克风获取的声音信号强度小于外侧麦克风获取的声音信号强度，那么就表明所述耳机处于佩戴状态；反之，就表明所述耳机不处于佩戴状态。
202、所述耳机根据所述耳机的佩戴模式生成佩戴模式信号。
本发明实施例中，所述佩戴模式信号可以用于指示所述耳机戴反，也可以用于指示所述耳机佩戴正确。因此，所述耳机可以根据确定耳机佩戴模式的确定结果来生成佩戴模式信号。
也即是说，在耳机确定出所述耳机戴反时，生成用于指示耳机戴反的佩戴模式信号，而在耳机佩戴正确时，生成用于指示所述耳机佩戴正确的佩戴模式信号。
需要说明的是，所述耳机可以只在耳机戴反时生成用于指示耳机戴反的佩戴模式信号；也可以只在耳机佩戴正确时生成用于指示耳机佩戴正确的佩戴模式信号；还可以在耳机确定出所述耳机戴反时，生成用于指示耳机戴反的佩戴模式信号，而在耳机佩戴正确时，生成用于指示所述耳机佩戴正确的佩戴模式信号，本发明实施例不做限定。
203、所述耳机通过与所述终端预先建立的通信连接将所述佩戴模式信号发送给所述终端。
204、所述终端通过所述通信连接接收所述耳机发送的佩戴模式信号，并根据所述佩戴模式信号控制所述终端播放的音频信号的声道输出。
本发明实施例中，终端在接收到佩戴模式信号后，就可以根据所述佩戴模式信号控制所述耳机的左右声道的输出。当所述佩戴模式信号用于指示所述耳机戴反时，所述终端就会将播放的音频信号切换声道输出；当所述佩戴模式信号用于指示所述耳机佩戴正确时，所述终端就不会做任何操作，即保持耳机左右声道当前的输出方式。
具体的，假设耳机的左听筒输出左声道，右听筒输出右声道，当用户将左听筒佩戴在用户右耳，或者将右听筒佩戴在用户左耳时，耳机就能够检测到耳机戴反，从而通知终端。终端因而会将原本左声道输出的音频信号切换为右声道输出，将右声道输出的音频信号切换为左声道输出，这样即使用户将耳机戴反，也可以听到符合双耳效应的音频信号。其中，双耳效应是人们依靠双耳间 的音量差、时间差和音色差判别声音方位的效应，所述音频信号可以是音乐、语音等终端输出的音频信号。当然，终端在切换声道后输出音频信号的期间，耳机同样可以检测耳机是否戴反，一旦用户将耳机听筒正确佩戴，那么终端就会按照默认的声道输出方式(即左听筒输出左声道，右听筒输出右声道)输出音频信号。
可见，在图2所示的方法中，耳机可以确定所述耳机的佩戴模式，并生成佩戴模式信号，从而将所述信号发送给终端，那么所述终端就可以根据佩戴模式信号，即耳机的佩戴模式(戴反或佩戴正确)来控制所述终端播放的音频信号的声道输出。通过这种方式，耳机可以检测是否戴反，而在耳机戴反时由终端自动切换声道，这样可以避免用户通过交换耳机左右听筒来切换声道，从而提高了耳机声道的切换效率。
基于图1所示的场景，本发明实施例公开了一种终端。请参阅图4a，图4a是本发明实施例公开的一种终端的结构示意图。其中，图4a所描述的终端400可以包括：至少一个处理器401，如CPU、输入设备402、输出设备403、存储器404、耳机接口405、蓝牙模块406、通信总线407、麦克风芯片408以及音频处理芯片409。其中：
耳机接口405与有线耳机建立通信连接。当耳机插入耳机接口405时，耳机与终端400之间即建立了有线连接，该有线连接包括耳机与终端400之间的音频输入通道，那么耳机与终端400之间就可以进行通信，如用户通过耳机向终端400输入声音信号、用户通过按压耳机上的物理按键向终端400发送如切换歌曲、调节音量、结束通话等指令，终端400将播放的音乐、视频中的声音信号等通过耳机输出给用户。其中，终端400与有线耳机之间进行通信的信号一般为模拟信号，如调制载波。
麦克风芯片408主要对声音信号进行解析，即接收器4021接收到由耳机经过音频输入通道发送的载波信号后，会发送给麦克风芯片408，麦克风芯片408从而将载波信号解析为电信号，并将解析得到的电信号发送给处理器401处理。
蓝牙模块406与(蓝牙)耳机建立通信连接。当(蓝牙)耳机与终端400 建立蓝牙连接时，(蓝牙)耳机与终端400之间就可以进行通信。其中，终端400与(蓝牙)耳机之间进行通信的信号一般为数字信号，如扫描码。蓝牙模块406还可以对耳机发送的数字信号进行解析，从而将解析结果发送给处理器401处理。
音频处理芯片409主要根据处理器401发送的音频指令对终端400播放的音频信号进行控制，如对音频数据进行声音渲染、切换声道输出、音量调节等。
存储器404存储供终端400使用的操作系统、计算机代码和数据等。存储器404可包括只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、硬盘驱动器等，本发明实施例中的应用程序存储在存储器404上。
输出设备403可以为显示屏、显示器、扬声器、或发送器等，用于显示或者播放图片或音视频文件，或者发送终端400产生的数据指令等。其中，显示屏或显示器通常配置了图形用户接口(Graphical User Interface，GUI)，GUI在终端400和在其上运行的操作系统或应用之间提供一个易于使用的用户接口。GUI以图形图像表示程序、文件和操作选项，用户可以通过操作显示屏或显示器选择并激活各种图形图像以便启动与之相关的功能和任务。
输入设备402可以为触控面板、或接收器4021等，接收器4021用于接收来自外部设备发送的数据指令。触控面板可以为触摸板或触摸屏，可基于各种感应技术，包括但不限于电容感应、电阻感应、表面声波感应、压力感应、光感应等接收用户的输入操作指令。触摸板或触摸屏可以与显示屏或者显示器集成在一起，也可以是单独的部件。其中，输入设备404可以是单点或多点输入设备。
需要说明的是，接收器4021与发送器可以集成为通信接口，用于接收外部设备发送的数据指令和向外部设备发送数据指令等。
处理器401对各种数据进行处理，并执行接收到的各种类型的指令，其可以控制终端400的各组件之间输入和输出数据的接收和操作；处理器401可以在单芯片、多芯片或多个电子元件上实现，并可采用多种体系结构，包括专用或嵌入式处理器、专用处理器、控制器、ASIC等。
通信总线407实现处理器401、输入设备402、输出设备403、存储器404、 耳机接口405、蓝牙模块406、麦克风芯片408以及音频处理芯片409这些组件之间的通信连接，其中：
接收器4021可以通过与耳机建立的通信连接接收所述耳机发送的佩戴模式信号，其中，所述佩戴模式信号用于指示所述耳机戴反或者所述耳机佩戴正确。接收器4021在接收到佩戴模式信号后，会将所述佩戴模式信号发送给处理器401进行处理。处理器401在获取到佩戴模式信号后，会根据佩戴模式信号控制所述终端400播放的音频信号的声道输出。
接收器4021通过与所述耳机建立的通信连接接收所述耳机发送的佩戴模式信号的具体方式可以为：
方式一、
在所述通信连接为有线连接，所述有线连接包括所述耳机与所述终端400的音频输入通道(能够传送由麦克风采集到的声音信号的通信线路)时，通过所述音频输入通道接收所述耳机发送的佩戴模式信号，其中，所述佩戴模式信号为载波信号，所述载波信号可以为指定的载波信号，如指定频率的调制载波，或者指定波形的载波信号，所述载波信号可以用来指示耳机戴反和耳机佩戴正确的至少一种。
请一并参阅图4b和图4c，其中，图4b是本发明实施例公开的耳机3.5mm接口示意图，图4c是本发明实施例公开的耳机3.5mm接口线路的示意图。现在的有线耳机通常为3.5mm耳机接口，所述耳机接口包括四个信号通道，如图4b所示，分别为左声道(+)通道，右声道(+)通道，麦克风(+)通道(也可以称为音频输入通道)以及地线(—)，其中，“+”表示高电压，“—”表示低电压。在图4c中，左声道通道和右声道通道一般与地线处于连接状态，而麦克风通道与地线之间存在开关，所述开关可以是硬件开关，也可以是软件开关。因此，麦克风通道与地线之间一般不会一直处于连接状态，而是在终端400运行特殊应用(如具有通话、录音等功能的应用)时才会与地线连接，从而处于工作状态。用户将耳机接口插入终端的耳机插孔后，如果终端400当前运行的应用具有通话功能，那么麦克风通道会与地线连接，用户可以通过麦克风将声音输入给终端400，也可以将一些控制指令发送给终端400，如在播放音乐时控制音量大小的指令，控制歌曲切换的指令，在通话时控制通话结束的指令等。同 时，耳机可以向终端400获取供电，从而开启距离传感器以检测耳机听筒与最近障碍物之间的距离。由于声音信号一般为波形信号，耳机通过麦克风向用户发送的也大多为波形信号，那么当耳机确定出所述耳机的佩戴模式，如耳机戴反时，可以通过音频输入通道将载波信号发送给终端400，终端400从而可以通过音频输入通道接收到音频信号，也可以接收到载波信号。
其中，所述载波信号用于指示耳机的佩戴模式，那么耳机和终端400之间可以预先约定指示耳机的佩戴模式的指定载波信号，可以为指定频率的调制载波，也可以为指定波形的载波信号(如正弦波)，本发明实施例不做限定。例如，终端400可以指定第一频率的调制载波用于指示耳机戴反，第二频率的调制载波用于指示耳机佩戴正确等。
方式二、
在所述通信连接为无线连接(如蓝牙连接)时，通过所述无线连接来接收所述耳机发送的佩戴模式信号，其中，所述佩戴模式信号为扩展编码。
本发明实施例中，现在的耳机还可以包括蓝牙耳机，即耳机与终端400通过蓝牙模块406建立连接，当然，耳机也可以与终端400建立Wi-Fi等无线连接。因此，当蓝牙等无线耳机与终端400建立无线连接时，如果耳机确定出耳机的佩戴模式，就可以通过蓝牙等无线连接方式将佩戴模式信号发送给终端400，以指示耳机的佩戴模式。例如，在用户将耳机戴反时，所述耳机就可以通过蓝牙向终端400发送用于指示耳机戴反的佩戴模式信号，那么接收器4021(具体为蓝牙模块406)就会接收到耳机发送的佩戴模式信号。
需要说明的是，现在的蓝牙耳机向终端400发送的信号为数字信号(即扫描码)，不同的扫描码对应不同功能的指示信号，所述指示信号包括有调节音量的信号、切换歌曲的信号、暂停和开始播放的信号等，如表1所示。因此，可以在现有的扫描码基础上，增加一个扩展编码，以指示耳机的佩戴模式。
举例来说，可以增加一个用于指示耳机戴反的扩展编码，所述扩展编码可以为除表1所示的扫描码之外的任意扫描码，如“003E7 999”，本发明实施例不做限定，那么，其对应的映射字符串为“CHANNEL_REVERSE”，以指示耳机戴反。当然，还可以增加一个用于指示耳机佩戴正确的扩展编码，本发明实施例不做限定。
表1
扫描码 功能 映射字符串
00c8 200 开始播放 MEDIA_PLAY
00c9201 暂停播放 MEDIA_PAUSE
00a3 163 下一曲 MEDIA_NEXT
00a5 165 上一曲 MEDIA_PREVIOUS
所述终端400还可以在接收器4021接收到佩戴模式信号时，对所述佩戴模式信号进行解析，得到解析结果，并根据解析结果控制所述终端400播放的音频信号的声道输出。
所述终端400对所述佩戴模式信号进行解析，得到解析结果的具体方式可以为：
方式一、
在所述佩戴模式信号为载波信号时，由麦克风芯片408将所述载波信号解析为电信号，发送给处理器401，处理器401从而与预先存储的用于指示耳机佩戴模式的信号进行比对，所述用于指示耳机佩戴模式的信号包括用于指示耳机戴反的信号和用于指示耳机佩戴正确的信号，如果解析后的信号与所述用于指示耳机戴反的信号匹配，所述终端确定所述耳机戴反；如果解析后的信号与所述用于指示耳机佩戴正确的信号匹配，所述终端确定所述耳机佩戴正确。
本发明实施例中，所述用于指示耳机佩戴模式的信号可以包括用于指示耳机戴反的信号和用于指示耳机佩戴正确的信号中的至少一种，本发明实施例不做限定。那么，所述终端在接收到所述载波信号后，可以与预先保存的各个载波信号进行对比，当确定所述解析后的信号为用于指示耳机佩戴模式的信号时，再进一步确定所述解析后的信号的频率或者波形是与用于指示耳机戴反的信号一致，还是与用于指示耳机佩戴正确的信号一致。通过这种方式即可对佩戴模式信号进行解析，得到解析结果。
方式二、
在所述佩戴模式信号为扩展编码时，由蓝牙模块406将该扩展比编码进行 解析，并将解析结果发送给处理器401，处理器401从而将解析后的扩展编码与用于指示耳机佩戴模式的扩展编码进行比对，所述用于指示耳机佩戴模式的扩展编码包括用于指示耳机戴反的扩展编码和用于指示耳机佩戴正确的扩展编码，如果所述扩展编码与所述用于指示耳机戴反的扩展编码匹配，所述终端确定所述耳机戴反；如果所述扩展编码与所述用于指示耳机佩戴正确的扩展编码匹配，所述终端确定所述耳机佩戴正确。
本发明实施例中，所述用于指示耳机佩戴模式的扩展编码包括用于指示耳机戴反的扩展编码和用于指示耳机佩戴正确的扩展编码中的至少一种，本发明实施例不做限定。那么，所述终端在接收到所述扩展编码后，可以与预先保存的各个扫描码进行对比，当确定所述扩展编码为用于指示耳机佩戴模式的扫描码时，再进一步确定所述扩展编码是与用于指示耳机戴反的扫描码一致，还是与用于指示耳机佩戴正确的扫描码一致。通过这种方式即可对佩戴模式信号进行解析，得到解析结果。
本发明实施例中，在所述佩戴模式信号用于指示所述耳机戴反时，所述佩戴模式信号由所述耳机在确定出所述耳机处于佩戴状态，且所述耳机的距离传感器检测到的距离不在指定距离范围内时，通过所述通信连接发送给所述终端400。那么处理器401就会根据所述佩戴模式信号控制音频处理芯片409将所述终端400播放的音频信号切换声道输出。
具体的，处理器401根据所述佩戴模式信号控制所述终端400播放的音频信号切换声道输出的具体方式可以为：具有音频播放功能的应用程序在读取存储器404中存储的音频文件后会发送给处理器401，处理器401会将所述音频文件进行解析，得到音频数据，并发送给音频处理芯片409，同时，处理器401在佩戴模式信号用于指示所述耳机戴反的情况下也会向音频处理芯片409发送声道切换指令，音频处理芯片409在接收到声道切换指令，并将音频数据进行声音渲染后，会将左声道输出的音频数据发送给右声道接口输出，右声道输出的音频数据发送给左声道接口输出。其中，左声道接口与耳机的左声道通道连接，右声道接口与耳机的右声道通道连接。
在耳机戴反时，处理器401可以在以下情况下根据所述解析结果或者所述佩戴模式信号控制音频处理芯片409对所述终端400播放的音频信号切换声道 输出：
方式一、
在解析结果为耳机戴反或者佩戴模式信号用于指示耳机戴反时，处理器401检测前台运行的应用程序是否为具有音频输出功能的应用程序，如音乐播放器、视频播放器以及游戏应用等。如果所述前台运行的应用程序为具有音频输出功能的应用程序，那么就会根据所述解析结果或者佩戴模式信号控制音频处理芯片409对所述终端400播放的音频信号切换声道输出。
本发明实施例中，具有音频输出功能的应用程序可以包括但不限于社交应用、通话应用、音乐播放器、视频播放器和游戏应用中的任意一种或几种。所述具有音频输出功能的应用程序也可以是指定的应用程序，如音乐播放器、视频播放器以及游戏等，本发明实施例不做限定。
因此，在麦克风芯片408或者蓝牙模块406对佩戴模式信号进行解析得到解析结果之后或者在接收器4021接收到佩戴模式信号之后，只有当前运行的应用程序也为具有音频输出功能的应用程序时，处理器401才控制音频处理芯片409对音频信号切换声道输出。而如果当前运行的应用程序不为具有音频输出功能的应用程序，输出设备403可以输出提示信息以提示用户耳机戴反。
可见，耳机戴反，且前台运行的应用程序为具有音频输出功能的应用程序时，所述终端400才对耳机声道进行切换，这样可以避免在不用切换声道的场景下切换声道，提高声道切换的精确性。
方式二、
在解析结果为耳机戴反或者佩戴模式信号用于指示耳机戴反时，处理器401根据解析结果或者佩戴模式信号生成用于提示用户耳机戴反，是否切换声道的提示信息，那么输出设备403就可以输出所述提示信息；输出设备403在输出提示信息后，输入设备402可以接收用户根据所述提示信息输入的声道控制指令。其中，所述声道控制指令用于指示进行声道切换或者保持当前声道输出。如果所述声道控制指令用于指示进行声道切换，那么所述处理器401再根据所述解析结果控制音频处理芯片409将终端400播放的音频信号切换声道输出。其中，所述提示信息可以为语音提示，也可以为文字提示。
本发明实施例中，在所述提示信息为文字信息时，输出设备403可以在显 示屏上显示该提示信息，也可以将该提示信息发送给穿戴设备，在穿戴设备的显示屏上显示；在所述提示信息为语音提示时，输出设备403可以通过蓝牙模块406或者耳机接口405将所述提示信息发送给耳机，通过耳机输出，本发明实施例不做限定。
其中，所述提示信息可以提示用户“耳机戴反，是否需要切换声道”，如果是文字提示，还可以在显示屏上显示提示框，请一并参阅图4d，图4d是本发明实施例公开的终端提示用户耳机戴反的场景之一的示意图。在图4d中，所述提示框可以包括文字内容“耳机戴反，是否需要切换声道”，还可以包括“是”和“否”两个按钮供用户选择。如果用户点击“是”，则可以通过输入设备402输入用于指示进行声道切换的声道控制指令；如果用户点击“否”，则可以通过输入设备402输入用于指示保持当前声道输出的声道控制指令。因此，处理器401在输出设备403输出所述提示信息后，可以检测预设时间段内输入设备402是否接收到用户根据所述提示信息输入的声道控制指令。如果所述声道控制指令用于指示进行声道切换，那么处理器401就会控制音频处理芯片409将所述终端400播放的音频信号切换声道输出；如果所述声道控制指令用于指示保持当前声道输出，那么处理器401就会控制音频处理芯片409按照默认的或者原有的声道输出方式输出所述终端400播放的音频信号。
可见，终端400在接收到用于指示耳机戴反的佩戴模式信号之后，可以提示用户，从而通过用户来确定是自动切换声道还是手动切换，增加了声道切换的灵活性。
需要说明的是，输入设备402接收到的声道控制指令的具体方式可以为：
方式一、
处理器401检测在输出设备403输出提示信息后的预设时间段内所述终端400的放置方式是否发生变化；在所述终端400的放置方式发生变化时，生成用于指示进行声道切换的声道控制指令；在终端400的放置方式未发生变化时，生成用于指示保持当前声道输出的声道控制指令，从而将生成的声道控制指令发送给输入设备402。
本发明实施例中，终端400可以预先设置用于指示进行声道切换的声道控制指令为在输出设备403输出提示信息的预设时间段内，所述终端400的放置方 式发生变化。因此，用户就可以在输出设备403输出提示信息之后，通过改变所述终端400的放置方式(例如，将水平放置的手机竖直放置)来控制终端400对耳机声道进行切换。如果用户在输出设备403输出提示信息后的预设时间段内未改变所述终端400的放置方式，那么处理器401可以控制音频处理芯片409不切换声道。当然，所述处理器401也可以设置在输出设备403输出提示信息后的预设时间段内如果没有检测到改变所述终端400的放置方式，也可以控制音频处理芯片409按照默认的处理方式对声道进行控制，如对耳机进行声道切换，本发明实施例不做限定。其中，所述预设时间段可以是5秒、10秒等，所述放置方式可以为正面朝上放置、侧面放置、背面朝上放置等，本发明实施例不做限定。
具体的，处理器401可以通过所述终端400内置的重力传感器来检测所述终端400的放置方式是否发生变化。
可见，在耳机戴反时，用户可以通过改变终端的放置方式来进行声道切换，在提高声道切换效率的同时又提高了用户的参与度，增加趣味性。
方式二、
处理器401检测在输出所述提示信息后的预设时间段内接收器4021是否接收到与所述终端400绑定的穿戴设备发送的声道控制指令；在通信接口4021未接收到所述穿戴设备发送的声道控制指令时，处理器401针对所述提示信息生成声道控制指令；而在接收器4021接收到所述穿戴设备发送的声道控制指令，且所述声道控制指令用于指示进行声道切换时，处理器401才会根据所述解析结果控制音频处理芯片409将所述终端400播放的音频信号切换声道输出。
本发明实施例中，所述预设时间段可以是5秒、10秒等，如果接收器4021在预设时间段内未接收到所述穿戴设备发送的声道控制指令，那么处理器401针对所述提示信息生成默认的声道控制指令，所述默认的声道控制指令可以是用于指示进行声道切换，也可以用于指示保持当前声道输出，本发明是实施例不做限定。
本发明实施例中，与所述终端400绑定的穿戴设备发送声道控制指令给所述终端400的情况可以包括两种情况：情况一、当所述终端400通过穿戴设备的显示屏显示提示信息的时候，用户可以在显示屏上通过点击“是”或“否” 来确定是否进行声道切换，那么所述穿戴设备就会根据用户在显示屏上的操作来生成声道控制指令，并通过与所述终端400建立的通信连接向所述终端400发送所述声道控制指令。情况二、当所述终端400通过穿戴设备的显示屏显示提示信息的时候，用户还可以通过同时晃动所述终端400和穿戴设备来指示所述终端400需要进行声道切换。
在耳机戴反时，用户可以通过穿戴设备来对耳机进行声道切换，终端400在长时间未收到穿戴设备发送的声道控制指令时自动控制声道输出，不仅可以提高耳机声道控制效率，还可以增加用户操作的趣味性和便捷性。
具体的，用户通过同时晃动所述终端400和穿戴设备来指示所述终端400需要进行声道切换的具体方式可以为：
处理器401可以检测所述终端400与绑定的穿戴设备在输出设备403输出提示信息的预设时间段内发生的甩动作事件是否匹配，所述甩动作事件与“摇一摇”功能类似，即用户是否同时摇动终端400和与其绑定的穿戴设备。具体可以是，当所述终端400发生第一甩动作事件，且处理器401检测到所述终端400绑定的穿戴设备发生第二甩动作事件时，处理器401会判断第一甩动作事件和第二甩动作事件包括的甩动作方向是否相同，如果相同，处理器401会进一步判断第一甩动作事件和第二甩动作事件包括的甩动作起始时间是否均位于在输出提示信息后的预设时间段内，如果均位于预设时间段内，处理器401确定所述终端400以及所述穿戴设备在预设时间段内发生的事件匹配，处理器401从而会生成用于指示进行声道切换的声道控制指令。
请一并参阅图5，图5是本发明实施例公开的生成声道控制指令的场景之一的示意图。如图5所示，终端400可以被用户拿在手上，并且用户拿终端400的同一只手上还可以佩戴有穿戴设备(如智能手环、智能手表、智能戒指等)，其中，穿戴设备是终端400绑定的穿戴设备，并且终端400可以通过蓝牙、Wi-Fi或红外线等与穿戴设备连接。在图5所示的场景中，用户可以朝着某一个方向同时甩动终端400和穿戴设备。相应地，当穿戴设备通过加速度传感器或者重力传感器检测到发生甩动作时，穿戴设备可以发送包括甩动作起始时间和甩动作持续时间的甩动作事件给终端400。相应地，终端400在输出提示是否切换声道的提示信息时，也可以通过加速度传感器或者重力传感器检测 所述终端400是否发生第一甩动作事件。以下为处理器401通过终端400与穿戴设备是否同时发生甩动作事件的具体实现方式：
方式一、如果终端400发生第一甩动作事件，所述终端400的处理器401会检测终端400绑定的穿戴设备是否发生第二甩动作事件，如果穿戴设备也发生第二甩动作事件，处理器401会判断第一甩动作事件和第二甩动作事件包括的甩动作方向是否相同，如果甩动作方向相同，处理器401会再次判断第一甩动作事件和第二甩动作事件包括的甩动作起始时间是否均位于在输出设备403输出提示信息后的预设时间段内。
如果第一甩动作事件和第二甩动作事件包括的甩动作起始时间均位于所述预设时间内，处理器401会进一步判断第一甩动作事件与第二甩动作事件包括的甩动作持续时长的差值是否小于预设阈值，如果第一甩动作事件与第二甩动作事件包括的甩动作持续时长的差值小于预设阈值，处理器401才确定所述终端400以及穿戴设备在预设时间内发生的事件匹配。
需要说明的是，第一甩动作事件和第二甩动作事件包括的甩动作方向相同可以理解为：当终端400中的加速度传感器检测到加速度突变(如5ms内从0.5变化到3)时，获取加速度最大时的方向，相应的，穿戴设备也会通过所述方式获得加速度最大时的方向，两方向夹角在一定范围内，如小于10度，即可认为第一甩动作事件和第二甩动作事件包括的甩动作方向相同。
方式二、处理器401还可以在方式一的基础上进一步判断第一甩动作事件和第二甩动作事件包括的甩动作持续时长是否均位于预设时间内。如果第一甩动作事件和第二甩动作事件包括的甩动作持续时长均位于预设时间内，处理器401可以再次判断第一甩动作事件与第二甩动作事件包括的甩动作起始时间的差值是否小于目标预设阈值。如果第一甩动作事件与第二甩动作事件包括的甩动作起始时间的差值小于目标预设阈值，处理器401才会确定所述终端400以及穿戴设备在预设时间内发生的事件匹配。将终端400与穿戴设备绑定，只有在终端400和穿戴设备发生的甩动作事件在预设时间内，才能表明终端400在用户的手上，既增加了对耳机声道切换的安全性，又增加了用户操作的趣味性。
其中，预设时间可以为5秒，10秒、15秒等，预设阈值可以为0.03秒后 0.05秒等，目标预设阈值也可以为0.03秒或0.05秒，预设阈值可以与目标预设阈值相同，也可以不同，本发明实施例不做限定。
可见，在图4所示的终端中，耳机在确定所述耳机的佩戴模式后，以用户将耳机戴反为例，会通过预先建立的通信连接向终端发送指示耳机戴反的佩戴模式信号，终端在接收到所述佩戴模式信号后可以将播放的音频信号切换声道输出，从而实现对耳机声道的切换。通过这种方式，耳机可以检测是否戴反，而在耳机戴反时由终端自动切换声道，这样可以避免用户通过交换耳机左右听筒来切换声道，从而提高了耳机声道的切换效率。进一步的，终端在接收到耳机戴反的佩戴模式信号之后，可以提示用户，从而通过用户来确定是自动切换声道还是手动切换声道，增加了耳机声道切换的灵活性。
基于图1所示的场景，本发明实施例公开了一种耳机。请参阅图6，图6是本发明实施例公开的一种耳机的结构示意图。其中，图6所示的耳机600预先与终端建立通信连接。如图6所示，所述耳机600可以包括：处理器601、通信接口602、距离传感器603以及通信总线604，其中：
距离传感器603设置分别设置在耳机600的左右听筒相对放置时的同侧，用于在检测耳机600到障碍物之间的距离(所述障碍物可以是耳廓，也可以是其他物体，如用户耳朵前方的头发、手机等)。
通信总线604可以实现处理器601、通信接口602以及距离传感器603这些组件之间的通信连接。其中：
处理器601可以确定耳机600的佩戴模式，并生成佩戴模式信号，通信接口602从而可以通过与终端预先建立的通信连接向终端发送所述佩戴模式信号。
本发明实施例中，耳机600与终端建立通信连接的方式有两种：一种为有线连接，即将耳机插头插入终端的耳机插孔，那么通信接口602即为耳机插头，另一种为无线连接，即耳机与终端通过蓝牙建立连接，那么通信接口602即为耳机600的蓝牙收发器。处理器601可以确定所述耳机600的佩戴模式，并根据佩戴模式生成佩戴模式信号，通信接口602从而会将所述佩戴模式信号发送给 终端。其中，所述佩戴模式包括耳机戴反模式和耳机佩戴正确模式，所述佩戴模式信号用于指示所述耳机戴反或者所述耳机佩戴正确。
具体的，所述耳机600包括左听筒和右听筒，左右听筒的相对位置分别设置有距离传感器603，所述距离传感器603可以是设置在左右听筒相对放置时左右听筒的同侧，如图3所示，可以是在听筒的外侧，也可以是在听筒的内侧，本发明实施例不做限定。因此，耳机600左右听筒的距离传感器603可以通过检测与耳廓的距离来确定所述耳机的佩戴模式。
具体实现中，距离传感器603可以检测耳机600的左右听筒到障碍物之间的距离。处理器601确定所述耳机600的佩戴模式的主要方式可以为：
距离传感器603耳机听筒与障碍物之间的的距离，并将所述距离发送给处理器601，处理器601判断所述距离是否在预设距离阈值内；在所述距离不在所述预设距离阈值内时，确定所述耳机600的佩戴模式为耳机戴反模式；在所述距离在所述预设距离阈值内时，确定所述耳机600的佩戴模式为耳机佩戴正确模式。
通信接口602通过所述通信连接将所述佩戴模式信号发送给终端的具体方式可以为：
方式一、
在所述通信连接为有线连接，所述有线连接包括所述耳机600与所述终端的音频输入通道时，通过所述音频输入通道将所述佩戴模式信号发送给所述终端，其中，所述佩戴模式信号为载波信号，所述载波信号可以为指定的载波信号，如指定频率的调制载波，或者指定波形的载波信号，所述载波信号可以用来指示耳机戴反和耳机佩戴正确的至少一种。
方式二、
在所述通信连接为无线连接(如蓝牙连接)时，通过所述无线连接将所述佩戴模式信号发送给所述终端，其中，所述佩戴模式信号为扩展编码。
可见，在图6所示的耳机中，耳机可以检测耳机的佩戴模式，并生成佩戴模式信号，从而告知给终端耳机的佩戴状态，以便于终端可以根据佩戴模式信号控制播放的音频信号的声道输出。也即是说，也即是说，终端可以在耳机戴 反时自动控制耳机左右听筒的声道输出，而避免了用户调换耳机听筒佩戴位置，从而可以提高耳机声道切换效率。
基于图1所示的场景，本发明实施例公开了另一种耳机声道控制方法。请参阅图7，图7是本发明实施例公开的另一种耳机声道控制方法的流程示意图。其中，图7所描述的方法可以应用于图4所示的终端400，所述终端预先与耳机建立有通信连接。如图7所示，所述耳机声道控制方法可以包括以下步骤：
701、终端通过与耳机建立的通信连接接收所述耳机发送的佩戴模式信号。
其中，所述佩戴模式信号用于指示耳机戴反或者耳机佩戴正确。
702、所述终端对所述佩戴模式信号进行解析，得到解析结果。
703、所述终端根据所述解析结果控制所述终端播放的音频信号的声道输出。
如果所述佩戴模式信号用于指示耳机戴反，所述终端最终会将所述终端播放的音频信号切换声道输出；如果所述佩戴模式信号用于指示耳机佩戴正确，所述终端可能会对当前的声道输出方式不做任何改变。
可见，在图7所示的方法中，终端可以根据耳机的佩戴模式(戴反或佩戴正确)来控制耳机左右听筒的声道输出方式，也即是说，终端可以在耳机戴反时自动控制耳机左右听筒的声道输出，而避免了用户调换耳机听筒佩戴位置，从而可以提高耳机声道切换效率。
基于图1所示的场景，本发明实施例公开了又一种耳机声道控制方法。请参阅图8，图8是本发明实施例公开的又一种耳机声道控制方法的流程示意图。其中，图8所描述的方法可以应用于图4所示的终端400，所述终端预先与耳机建立有通信连接。如图8所示，所述耳机声道控制方法可以包括以下步骤：
801、终端通过与耳机建立的通信连接接收所述耳机发送的佩戴模式信号。
其中，所述佩戴模式信号用于指示耳机戴反。
802、所述终端对所述佩戴模式信号进行解析，得到解析结果。
其中，所述解析结果表示所述耳机戴反。
803、所述终端检测前台运行的应用程序是否为具有音频输出功能的应用 程序。
其中，具有音频输出功能的应用程序可以包括但不限于音乐播放器、视频播放器、通话应用以及游戏应用中的至少一种。
804、如果所述前台运行的应用程序为具有音频输出功能的应用程序，所述终端根据所述解析结果将播放的音频信号切换声道输出。
可见，在图8所示的方法中，耳机戴反，且前台运行的应用程序为具有音频输出功能的应用程序时，所述终端才对耳机声道进行切换，这样可以避免在不用切换声道的场景下切换声道，提高声道切换的精确性。
基于图1所示的场景，本发明实施例公开了又一种耳机声道控制方法。请参阅图9，图9是本发明实施例公开的又一种耳机声道控制方法的流程示意图。其中，图9所描述的方法可以应用于图4所示的终端400，所述终端预先与耳机建立有通信连接。如图9所示，所述耳机声道控制方法可以包括以下步骤：
901、终端通过与耳机建立的通信连接接收所述耳机发送的佩戴模式信号。
其中，所述佩戴模式信号用于指示耳机戴反。
902、所述终端对所述佩戴模式信号进行解析，得到解析结果。
其中，所述解析结果表示所述耳机戴反。
903、所述终端根据所述解析结果生成用于提示是否切换声道的提示信息。
904、所述终端输出所述提示信息。
其中，所述终端可以是在所述终端的显示屏上输出文字提示，也可以是通过耳机输出语音提示，还可以在与之绑定的穿戴设备的显示屏上输出文字提示，本发明实施例不做限定。
905、所述终端接收用户根据所述提示信息选择的声道控制指令。
906，如果所述声道控制指令用于指示进行声道切换，所述终端根据解析结果将播放的音频信号切换声道输出。
907、如果所述声道控制指令用于指示保持当前声道输出，所述终端不做任何操作。
可见，在图9所示的方法中，终端在接收到耳机戴反的佩戴模式信号之后，可以提示用户，从而通过用户来确定是自动切换声道还是手动切换，增加了声 道切换的灵活性。
基于图1所示的场景，本发明实施例公开了一种终端。请参阅图10，图10是本发明实施例公开的一种终端的结构示意图。本发明实施例提供的终端可以用于实施上述图7-图9所示的本发明各实施例实现的方法，为了便于说明，仅示出了与本发明实施例相关的部分。

基于图1所示的场景，本发明实施例公开了一种终端。请参阅图11，图11是本发明实施例公开的一种终端的结构示意图。其中，图11所描述的终端1100预先与耳机建立有通信连接。如图10所示，所述终端1100可以包括通信模块1101、解析模块1102以及控制模块1103，其中：
通信模块1101可以通过与所述耳机建立的通信连接接收所述耳机发送的佩戴模式信号，其中，所述佩戴模式信号用于指示所述耳机戴反或者所述耳机佩戴正确。
解析模块1102可以对所述通信模块接收到的所述佩戴模式信号进行解析，得到解析结果。
控制模块1103可以根据所述解析模块得到的解析结果控制所述终端1100播放的音频信号的声道输出。
在一种实施方式中，所述终端1100还可以包括：
检测模块1104可以在解析模块1102对佩戴模式信号进行解析得到解析结果，且所述解析结果为耳机戴反时，检测前台运行的应用程序是否为具有音频输出功能的应用程序，如果检测模块1104检测到前台运行的应用程序为具有 音频输出功能的应用程序，那么就会触发控制模块1103根据解析结果将终端1100播放的音频信号切换声道输出。
耳机戴反，且前台运行的应用程序为指定应用程序才对耳机声道进行切换，这样可以避免在不用切换声道的场景下切换声道，提高声道切换的精确性。
在另一种实施方式中，所述终端1100还可以包括生成模块1105、输出模块1106以及输入模块1107，其中：
生成模块1105可以根据所述解析模块1102得到的解析结果生成用于提示是否切换声道的提示信息。
输出模块1106可以输出所述生成模块1105生成的提示信息。
其中，所述提示信息可以为语音提示，也可以为文字提示，本发明实施例不做限定。
输入模块1107可以在输出模块1106输出提示信息之后，接收用户根据所述提示信息输入的声道控制指令。其中，所述声道控制指令可以用于指示进行声道切换，也可以用于指示保持当前声道输出。
那么，控制模块1103就可以在输入模块1107接收到用于进行声道切换的声道控制指令，且解析结果为耳机戴反时，将所述终端1100播放的音频信号切换声道输出。
此外，生成声道控制指令的具体方式可以为：
检测模块1104检测在输出模块1106输出所述提示信息后的预设时间段内所述终端1100的放置方式是否发生变化。如果所述终端1100的放置方式发生变化，生成模块1105生成用于指示进行声道切换的声道控制指令；如果所述终端1100的放置方式未发生变化，生成模块1105生成用于指示保持当前声道输出的声道控制指令。那么控制模块1103根据生成模块1105生成的声道控制指令控制播放的音频信号的声道输出。其中，所述放置方式可以包括正面朝上，侧面放置，正面朝下等。
在耳机戴反时，用户可以通过改变终端1100的放置方式来进行声道切换，在提高声道切换效率的同时又提高了用户的参与度，增加趣味性。
本发明实施例中，通信模块1101还可以接收与所述终端1100绑定的穿戴设备发送的声道控制指令。
在输出模块1106输出所述提示信息后的预设时间段内通信模块1101是否接收到所述穿戴设备发送的声道控制指令。如果通信模块1101未接收到所述穿戴设备发送的声道控制指令，生成模块1105针对所述提示信息生成声道控制指令；如果通信模块1101接收到所述穿戴设备发送的声道控制指令，且所述声道控制指令用于指示进行声道切换，控制模块1103会将所述终端1100播放的音频信号切换声道输出。
在耳机戴反时，用户可以通过穿戴设备来对耳机进行声道切换，并在长时间未收到穿戴设备的声道控制指令时自动控制声道输出，不仅可以提高耳机声道控制效率，还可以增加用户操作的趣味性和便捷性。
需要说明的是，一方面，通信模块1101的功能可以集成到通信接口，通信接口可以包括接收器和发送器，解析模块1102、处理模块1103、检测模块1104以及生成模块1105的功能可以集成到处理器，输出模块1106可以集成到输出设备，输入模块1107可以集成到输入设备；另一方面，输入设备可以包括接收器，输出设备可以包括发送器，本发明实施例不做限定。
可见，在图11所所示的终端中，耳机在检测到所述耳机的佩戴模式，以用户将耳机戴反为例，耳机会通过预先建立的通信连接向终端发送指示耳机戴反的佩戴模式信号，终端在接收到所述佩戴模式信号并解析得到解析结果后，可以将播放的音频信号切换声道输出，从而实现对耳机声道的切换。通过这种方式，耳机可以检测是否戴反，而在耳机戴反时由终端自动切换声道，这样可以避免用户通过交换耳机左右听筒来切换声道，从而提高了耳机声道的切换效率。进一步的，终端在接收到耳机戴反的佩戴模式信号之后，可以提示用户，从而通过用户来确定是自动切换声道还是手动切换声道，增加了耳机声道切换的灵活性。
基于图1所示的场景，本发明实施例公开了又一种耳机声道控制方法。请参阅图12，图12是本发明实施例公开的又一种耳机声道控制方法的流程示意图。其中，图12所示的方法可以应用于耳机，所述耳机预先于终端建立通信连接。如图12所示，所述方法可以包括以下步骤：
1201、耳机检测所述耳机的佩戴模式。
1202、所述耳机根据所述耳机的佩戴模式生成佩戴模式信号。
其中，如果检测结果为耳机处于耳机戴反模式，那么所述佩戴模式信号用于指示耳机戴反；如果检测结果为耳机处于耳机佩戴正确模式，那么所述佩戴模式信号用于指示耳机佩戴正确。
1203、所述耳机通过与终端建立的通信连接将所述佩戴模式信号发送给所述终端。
可见，在图12所示的方法中，耳机可以确定耳机的佩戴模式，并生成佩戴模式信号，从而告知给终端耳机的佩戴状态，以便于终端可以根据佩戴模式信号控制播放的音频信号的声道输出。也即是说，也即是说，终端可以在耳机戴反时自动控制耳机左右听筒的声道输出，而避免了用户调换耳机听筒佩戴位置，从而可以提高耳机声道切换效率。
基于图1所示的场景，本发明实施例公开了一种耳机。请参阅图13，图13是本发明实施例公开的一种耳机的结构示意图。其中，图13所示的耳机1300预先与终端建立通信连接。如图13所示，所述耳机1300可以包括确定模块1301、生成模块1302以及通信模块1303，其中：
确定模块1301可以确定耳机1300的佩戴模式，其中所述佩戴模式可以包括耳机戴反模式和耳机佩戴正确模式。
生成模块1302可以根据确定模块1301的确定结果生成佩戴模式信号。
其中，如果确定结果为耳机处于耳机戴反模式，那么所述佩戴模式信号用于指示耳机戴反；如果确定结果为耳机处于耳机佩戴正确模式，那么所述佩戴模式信号用于指示耳机佩戴正确。
通信模块1303可以通过与所述终端建立的通信连接将所述佩戴模式信号发送给所述终端。
具体实现中，所述耳机1300还可以包括检测模块1304和判断模块1305，其中：
确定模块1301可以确定耳机1300是否处于佩戴状态。在确定模块1301 确定出耳机1300处于佩戴状态时，检测模块1304可以检测所述耳机1300与障碍物的距离，并将所述距离发送给判断模块1305，判断,模块1305可以判断所述距离是否在预设距离阈值内。如果所述距离不在所述预设距离阈值内，确定模块1301确定耳机1300的佩戴模式为耳机戴反模式；如果所述距离在所述预设距离阈值内，确定模块1301确定耳机1300的佩戴模式为耳机佩戴正模式。
可见，在图13所示的耳机中，耳机可以确定耳机的佩戴模式，并生成佩戴模式信号，从而告知给终端所述耳机的佩戴模式，以便于终端可以根据佩戴模式信号控制播放的音频信号的声道输出。也即是说，终端可以在耳机戴反时自动控制耳机左右听筒的声道输出，而避免了用户调换耳机听筒佩戴位置，从而可以提高耳机声道切换效率。
请参阅图14，图14是本发明实施例公开的一种耳机声道控制系统的结构示意图。如图14所示，图14所示的系统可以包括终端1401和耳机1402，所述终端1401与所述耳机1402之间预先建立通信连接，其中：
耳机1402，用于确定耳机1402的佩戴模式，并根据所述耳机1402的佩戴模式生成佩戴模式信号，从而通过所述通信连接将所述佩戴模式信号发送给终端1401。其中，所述佩戴模式包括耳机戴反模式和耳机佩戴正确模式，所述佩戴模式信号可以用于指示耳机1402戴反，也可以用于指示耳机1402佩戴正确。
终端1401在通过所述通信连接接收到耳机1402发送的佩戴模式信号后，会对所述佩戴模式信号进行解析，得到解析结果，并根据解析结果控制终端1401播放的音频信号的声道输出。
可见，在图14所示的系统中，耳机可以检测所述耳机的佩戴模式，并生成佩戴模式信号，从而将所述信号发送给终端，那么所述终端在对佩戴模式信号进行解析得到解析结果后，就可以根据解析结果，即耳机的佩戴模式(戴反或佩戴正确)来控制所述终端播放的音频信号的声道输出。通过这种方式，耳机可以检测是否戴反，而在耳机戴反时由终端自动切换声道，这样可以避免用户通过交换耳机左右听筒来切换声道，从而提高了耳机声道的切换效率。
