A sound output apparatus includes two sound output units and a connector(212). The connector receives audio output signals from a terminal device. The sound output units are connected to the connector. Different sound delivery media are used for different sound output units. The output unit includes an earphone body(204) and a variable duct unit. Air is inputted and outputted through the variable duct unit. The sound delivery medium includes different earphone cables with different lengths. The sound delivery medium with a longer line has more flexible lines in a cable. |
