autorzy: Gou Wenxi, Ren Xuan, Sun Bei, Zuo Huidan
The invention is a special type of earphone, in which an earphone jack is added to the ordinary earphone to insert another earphone or headphone so that the sound used to come from one earphone can come from two connected earphones or headphones. If everyone had such earphone, music that could only be played through one earphone could be quietly shared by 10, 20 or even more people through connected earphones.
