手机没电了怎么办？新型T恤用音乐为手机充电
A prototype T-shirt that charges mobiles has been unveiled by telecoms giant Orange.最近，电信巨头Orange公开了一件能为手机充电的T恤。
Users just have to plug their phone into the T-shirt for a quick top-up charge whenever they need it.用户只要在需要的时候，将手机放在T恤上就可以快速充电。
The futuristic garment works by using noise-responsive technology - simply, the louder the music, then the quicker the phone charges.这种未来的衣服采用噪音响应技术，简单地来说，周围的声音越响，手机充电速度越快。
It uses an A4-size piece of piezoelectric film in a T-shirt to absorb pressure from sound waves. It converts these into an electrical charge, which it then transfers from its battery into a lead that fits most phones.它的内部置有一张A4大小的压电式薄膜，可以从声波中吸收一定的压强。这些压强被压成电流输出，通过专门的充电线，电流从T恤内部的蓄电池中转入到各种型号的手机电池中。
