其中，需要指出的是，耳机与终端之间的连接方式可以是用户选定的某种连接方式，也可以耳机根据具体场景进行选择的自动切换模式。
如图1a所示，该图1a描述一种具体的耳机结构。该耳机包括通信模块、GNSS(Global Navigation Satellite System，全球卫星导航系统)定位模块和音频模块。
其中，通信模块包括蓝牙(Bluetooth，BT)，无线保真(Wireless Fidelity，WIFI)以及射频(Radio Frequency，RF)。具体的，BT是一种无线技术标准，可实现固定设备、移动设备和个人域网之间的短距离数据交换(使用2.4-2.485GHz的ISM波段的UHF无线电波)；WIFI是一种可以将个人电脑、手持设备(如pad、手机)等终端已无线互相连接的技术；RF是一种通信射频，是基于2G/3G/4G的通信。
GNSS定位模块支持美国的GPS、俄罗斯的GLONASS和中国的BDS。

MDL_bt<RSSI_bt<＝MUL_bt时，BT的信号强度为中；
DL_bt<RSSI_bt<＝MDL_bt时，BT的信号强度为弱。
BT的信号强度为弱时，需要保证DL_bt大于BT的灵敏度，否则导致耳机通过BT传输的数据误码率高，通话质量差，甚至断线。
S103、当所述蓝牙信号强度大于第一预设强度时，所述耳机通过蓝牙与所述终端建立连接。
其中，需要指出的是，第一预设强度可以是DL_bt、MUL_bt、MDL_bt中的任何一个值。本实施例在此对第一预设强度不做限制。

MDL_WIFI<RSSI_WIFI<＝MUL_WIFI时，WIFI的信号强度为中；
DL_WIFI<RSSI_WIFI<＝MDL_WIFI时，WIFI的信号强度为弱。
WIFI的信号强度为弱时，需要保证DL_WIFI大于WIFI的灵敏度，否则导致耳机通过WIFI传输的数据误码率高，通话质量差，甚至断线。
其中，需要指出的是，第二预设强度可以是DL_WIFI、MUL_WIFI、MDL_WIFI中的任何一个值。本实施例在此对第二预设强度不做限制。
可以看出，本发明实施例的方案中，当检测到耳机开启时，确定所述耳机与所述终端之间的连接方式；当所述耳机与所述终端之间的连接方式为自动切换模式时，确定所述耳机与所述终端之间的蓝牙信号强度；当所述蓝牙信号强度大于第一预设强度时，所述耳机通过蓝牙与所述终端建立连接；当检测到所述蓝牙信号的强度小于所述第一预设强度且无线保真信号的强度大于第二预设强度时，所述耳机中断与所述终端之间的蓝牙连接，通过无线保真与所述终端建立连接。从而可知，通过实施本发明提供的技术方案，能够根据耳机与终端之间的连接方式的信号强度确定是否切换到另一种更优的连接方式，从而确 保耳机接收音频的质量。

DL_rf<RSSI_rf<＝MDL_rf时，RF的信号强度为弱。
RF的信号强度为弱时，需要保证DL_rf大于RF的灵敏度，否则导致耳机通过RF传输的数据误码率高，通话质量差，甚至断线。
其中，需要指出的是，第三预设强度可以是DL_rf、MUL_rf、MDL_rf中的任何一个值。本实施例在此对第三预设强度不做限制。
其中，需要指出的是，所述通过射频信号与所述终端建立连接之后，还需要考虑所述射频信号小于所述第三预设强度的情况，请见S207。

可以看出，本发明实施例的方案中扩充了根据具体场景实现WIFI、BT与RF之间切换的步骤，通过实施本发明提供的技术方案，能够根据信号强度进行连接方式的切换，从而保证耳机接收到的音频的质量。
可选的，在本发明的另一个实施例中，耳机开启后，用户没有进行自定义 耳机与移动终端的连接方式，则默认为自动选择模式，自动选择模式遵循下面的规则：
(1)优先使用BT作为连接方式；
(2)若BT信号强度为弱时，且RSSI_bt<＝DL_bt时，优先使用WIFI作为连接方式；
(3)若WIFI信号强度为弱时，且RSSI_WIFI<＝DL_WIFI时，使用RF作为连接方式；
(4)使用RF作为连接方式时，耳机可以监测WIFI/BT的信号，WIFI/BT的信号强度大于弱信号的下限时，可以切换到WIFI或者BT作为连接方式，优先选择BT作为连接方式；
(5)使用WIFI作为连接方式时，耳机可以检测BT的信号，BT的信号强度大于弱信号的下限时，可以切换到BT作为连接方式。
可选的，在本发明的另一个实施例中，耳机开后，用户可以自定义耳机与移动终端之间的连接方式，用户自定义可以分为全自定义和半自定义两种：
(1)全自定义，用户指定BT/WIFI/RF其中一种作为耳机与移动终端之间的连接方式，且不可切换；
(2)半自定义，用户指定BT/WIFI/RF其中一种作为耳机与移动终端之间的连接方式，耳机可以根据应用场景来切换连接方式。
耳机自动选择、切换耳机与移动终端之间的连接方式的算法流程图如下：
(1)耳机置于Auto状态，耳机自动选择、切换耳机与移动终端之间的连接方式；
(2)耳机优先判断耳机与移动终端之间BT的信号状态，
RSSI_bt>DL_bt，选择BT作为耳机与移动终端之间的连接方式，
RSSI_bt<＝DL_bt,不选择BT作为耳机与移动终端之间的连接方式；
(3)若BT不能作为耳机与移动终端之间的连接方式，优先判断耳机与移动终端之间WIFI的信号状态，
RSSI_WIFI>DL_WIFI，选择WIFI作为耳机与移动终端之间的连接方式，
RSSI_WIFI<＝DL_WIFI,不选择WIFI作为耳机与移动终端之间的连接方 式；
若WIFI不能作为耳机与移动终端之间的连接方式，则选择RF作为连接方式，即
RSSI_WIFI<＝DL_WIFI&&RSSI_rf>DL_rf，选择RF作为耳机与移动终端之间的连接方式
(4)若RSSI_rf<＝DL_rf，则耳机不可用；
(5)若选择了WIFI作为耳机与移动终端之间的连接方式，此时耳机可以间歇式地去搜索判断耳机与移动终端之间BT的信号状态，
RSSI_bt>DL_bt，切换耳机与移动终端之间的连接方式为BT，
RSSI_bt<＝DL_bt，仍然保持WIFI作为耳机与移动终端之间的连接方式；
(6)若选择了RF作为耳机与移动终端之间的连接方式，此时耳机可以间歇式地区搜索判断耳机与移动终端之间BT/WIFI的信号状态，
RSSI_WIFI>DL_WIFI，切换耳机与移动终端之间的连接方式为WIFI，
RSSI_WIFI<＝DL_WIFI，保持RF作为耳机与移动终端之间的连接方式；
RSSI_bt>DL_bt，切换耳机与移动终端之间的连接方式为BT，
RSSI_bt<＝DL_bt，仍然保持RF作为耳机与移动终端之间的连接方式。
如图2a所示，在本发明的另一个实施例中，图2a中半圆形ABE是BT的信号覆盖区，在此区域里，BT的信号强度如下：
DL_bt<RSSI_bt<＝UL_bt
在这个区域可以使用BT作为耳机与移动终端的连接方式，可以保证通信质量；
矩形BCDE区域，BT信号的强度和WIFI的信号强度如下：
RSSI_bt<＝DL_bt
DL_WIFI<RSSI_WIFI<＝UL_WIFI
将BCDE区域定义为WIFI信号区，在这个区域可以使用WIFI作为耳机与移动终端的连接方式，可以保证通信质量；
剩下的区域里，BT/WIFI/RF的信号强度如下：
RSSI_bt<＝DL_bt
RSSI_WIFI<＝DL_WIFI
DL_rf<RSSI_rf<＝UL_rf
将该区域定义为RF信号去，在这个区域内只能使用RF作为耳机与移动终端的连接方式，若使用BT或者WIFI作为连接方式，则无法保证通信质量。
