摘要

PURPOSE: A connector of an earphone plug is provided to securely connect an earphone jack and the earphone plug by designing terminals respectively corresponding to a ground terminal, left and right signal terminals and a microphone terminal of the earphone plug on a printed circuit board without installing a separate earphone jack in an audio device. CONSTITUTION: A connector of an earphone plug(10) includes a printed circuit board(1), and the first, second and third connecting terminals(4,5,6). The printed circuit board has an insertion hole(3) into which the earphone plug is inserted. The first, second and third connecting terminals are placed on the positions of the printed circuit board, which correspond to the ground terminal(11), left and right signal terminals(12) and microphone terminal(13), and connected to external signal lines. The first, second and third connecting terminals are composed hollowed metal elastic substances such that the connecting terminals are securely connected to the earphone plug.
