Electrode adopts the needle probes electrode.

Beneficial effect of the present invention is: by adopting left and right sides anti-misconnection concaveconvex structure, make the volume-diminished of magnetic connector, changing annular electrode into needle probes and doing electrode of magnetic connector makes large diameter annular magnet into two small size bar magnets, in order to dwindle the connector external diameter; It is wrong to utilize concaveconvex structure to prevent that the termination from connecting, thereby realizes the volume-diminished of magnetic force frames connecting with headphone.
