If it is determined that the signal is output from the speaker 111 (S304: Y), the process proceeds to S305.

  In the process of S305, an audio signal reproduced on the information terminal 12 is output from the speaker 111 of the information processing apparatus. That is, instead of the headphone 130 connected to the headphone terminal 129 of the information terminal 12, output using the speaker 111 of the information processing apparatus 11 is performed. This is performed by the interface 127 serving as a communication unit of the information terminal 12 transmitting an audio signal to the interface 117 serving as the communication unit of the information processing apparatus 11 using short-range wireless communication.
