Electronic apparatus

An electronic apparatus comprising:

• a speaker;
• a terminal configured to input an audio signal from an external device;
• an amplifier configured to amplify the audio signal which is input from the terminal, and to output audio from the speaker;
• a power supply circuit configured to supply power to the amplifier from a battery when power is not supplied externally;
• a switch configured to switch between a first path by which the amplifier is connected to a sound controller operating when the electronic apparatus is in an operative state and a second path by which the terminal and the amplifier are connected to each other without the sound controller;
• a setting module configured to set data which indicates whether audio output from the speaker is to be enabled or disabled;
• a first state detector configured to detect a first state where an external terminal for inputting the audio signal is connected to the terminal;
• and
• a controller configured to control the switch to select the second path after transition of the electronic apparatus from the operative state to a non-operative state and control the power supply circuit to supply the power from the battery to the amplifier, when a residual charge capacity of the battery is not less than a predetermined value, the data indicates enabling of audio output, and the first state is detected.
