PURPOSE: A waterproof structure for the input-output connector of a portable audio player is provided to prevent a short circuit in an inner circuit from water by including a waterproof function. CONSTITUTION: Connecting terminals(121-124) of an input-output connector are directly connected with an inner PCB(Printed Circuit Board). The connecting terminal is turned on or off by enabling a user to push an elastic protrusion unit. The connecting terminal is electrically connected with the inner PCB through a switch(133) located within a protection member. When the terminal of a plug is connected with the terminal of the input-output connector, the plug pushes the protrusion unit. The input-output connector is electrically connected with the inner PCB.
