蓝牙耳机定位原理 - 手机如何追踪已配对设备
中文内容：
许多用户好奇"连过手机的蓝牙耳机真的能定位吗？"这个问题的答案其实是肯定的。
当蓝牙耳机曾经与手机配对过，只要满足以下条件即可实现定位：
1. 手机蓝牙功能保持开启状态
2. 耳机处于开机运行状态
3. 设备之间距离在有效范围内
此时手机蓝牙界面会显示已配对的设备信息，通过信号强度可以判断耳机的大致位置。这种定位方式在短距离追踪场景中非常实用。

Many users wonder "Can previously paired Bluetooth headphones really be tracked?" The answer is definitely yes.
When Bluetooth headphones have been paired with a phone before, positioning can be achieved as long as:
1. The phone's Bluetooth remains enabled
2. The headphones are powered on
3. Devices are within effective range
In this case, the phone's Bluetooth interface will display paired device information, and the signal strength can indicate the approximate location of the headphones. This positioning method is particularly useful for short-range tracking scenarios.
