PURPOSE:To charge the secondary battery on a headphone side without any special operation by engaging the headphone with a transmitter while a terminal and a contact are in contact with each other. CONSTITUTION:With no wireless headphone 2 in use, a top of a hanger part 31 of the headphone 2 is engaged with an engaging recessed part 15 at the upper part of a transmitter 1 and the headphone 2 is held on the transmitter 1. In this case, pins 16A, 16B implanted to the recessed part 15 are inserted to holes 51A, 51B at the bottom face of a protrusion 33. Thus, the pins 16A, 16B are in contact with the holes 51A, 51B and a current of the charging power supply flows to secondary batteries 45A, 45B in unit sections 32A, 32B via a contact in the holes 51A, 51B to apply charging. |
