蓄电池中的电力不仅可以用来给电子设备充电，而且还可以点亮背包内部的光导纤维。
Power from the battery is used not only to charge mobile devices, but also light up optical fibers inside of the bag.
当纤维在声波的作用下发出振动时，它会产生一种能够被探测到的电子信号。
When acoustic waves cause the fibre to vibrate, it produces a corresponding electrical signal that can be detected.
在应用过程中，需在纤维外部加上一层反光曾，然后通过施加电子信号来控制其振动。
This involves covering the fibres with a reflective coating, and then controlling their vibration by applying electrical signals.
