Accordingly, when the portable electronic device 1 is mounted on the first connector 16, a sound signal of the portable electronic device 1 is input to the external speaker 10 through the audio input terminal, and the input sound signal is reproduced. It is reproduced by the circuit and output as sound through the speaker unit 14. At the same time, power of the external speaker 10 may be supplied to the portable electronic device 1 through the power output terminal to charge the battery of the portable electronic device 1.
