Specifically, unlike the probe in the prior art, the elastic conduction portion 12 on the elastic sheet 1 can be elastically deformed in the insertion direction inclined to the connection portion of the earphone, so as to realize reliable conduction with the conduction portion on the connection portion of the earphone. It should be appreciated that the probe is modified to be a spring piece, which is also beneficial to avoid the situation of needle or earphone jamming. In addition, it should be known that, when the probe in the prior art is crowded, the outer peripheral face of probe can take place sliding friction with the connecting portion of earphone to make the connecting portion of probe or earphone reduce life because of wearing and tearing, shell fragment 1 among this technical scheme then can effectively reduce the friction to the earphone through elastic deformation, avoids the outline of fish tail earphone.
