Abstract

The utility model relates to a voice socket which is installed on an electronic device. The socket comprises an insulating body, an interfering element and a terminator group. Abutting part is arranged on one end of the insulating body and has an inserting hole in axial direction. An inserting groove passing through upper and lower surfaces of the insulating body is arranged on an adjacent inserting hole on one side of the insulating body. The interfering element arranged in the inserting groove comprises upper and lower elastic ends and an interfering part that is used for connecting two elastic ends. The interfering part of the interfering element interferes with the butting plug when the abutting jointing plug is inserted, and in such way, the inserting and pulling force is increased, making the butting plug fixed in the voice socket so as to increase mechanical and electronic performance of the voice socket.
