Abstract:
1. An electronic apparatus comprising: a speaker; a terminal configured to receive an audio signal from an external apparatus; an amplifier configured to amplify the audio signal received from the terminal, and to output sound from the speaker; a power supply circuit configured to supply power to the amplifier; a switch module configured to switch between (1) a first path which connects the terminal and the amplifier and bypasses a sound controller, the sound controller configured to operate when the electronic apparatus is in an operative state, and (2) a second path which connects the terminal and the amplifier via the sound controller; an audio control module configured to adjust a signal level of the audio signal when the electronic apparatus is in the operative state; and a controller configured to cause the switch module to change over to the first path when the electronic apparatus transitions from the operative state to a non-operative state and cause the switch module to change over to the second path when the electronic apparatus transitions from the non-operative state to the operative state, and to continue the supply of power to the amplifier by the power supply circuit and adjust an output of the amplifier based on the signal level adjusted by the audio control module, if the external apparatus is connected to the terminal when the operative state of the electronic apparatus is transitioned.
