Description

无线耳机以及电子设备 技术领域
本发明涉及耳机技术领域，更具体地，涉及一种耳柄可拆卸地无线耳机以及应用了该无线耳机的电子设备。
背景技术
蓝牙耳机种类主要分为：单声道蓝牙耳机、立体声蓝牙耳机和全无线蓝牙耳机。
全无线蓝牙耳机与传统蓝牙耳机最大的区别在于采用多点无线互联技术，实现了左右耳之间的无线连接。这种耳机电连接和信号连接采用无线连接的方式。全无线耳机的左、右耳塞都能单独工作。需要变身双声道立体声耳机时，开启两个耳塞即可。这种耳机在分享音乐时不会被线材牵绊，使用起来也更加便捷。
但是全无线蓝牙耳机目前普遍存在由于电池容量有限导致使用时间较短、需要经常充电的问题。尤其要是在使用过程中需要中断音乐或者放下手中的工作来充电。这给使用者带来困扰，降低了用户体验感。
