An earphone socket, an electronic device, an electronic apparatus and an electronic system, which belong to the technical field of electronics. The earphone socket comprises an insulating base body and at least one metal contact terminal located in the insulating base body, wherein the insulating base body comprises an upper lug boss and a lower lug boss which are connected from top to bottom, and the connection parts of the upper lug boss and the lower lug boss enclose and form an insertion hole; and opposite boss surfaces between the two, i.e. the upper lug boss and the lower lug boss also form a drawer groove at an outer side of the insulating base body, the drawer groove being used for installing a circuit board in an insertion manner along the guidance of the drawer groove; and the metal contact terminal is used for connecting an audio plug inserted in the insertion hole with a corresponding conductive trace on the circuit board installed in the drawer groove. The present invention solves the problem in the related art that an earphone socket can be bonded to a circuit board only with the cooperation of an outside structure, thereby achieving the effects that the earphone socket can be in contact with a circuit board individually without the cooperation of the outside structure, and the circuit board can be preferably fixed. |
