Electronic apparatus

Abstract

According to one embodiment, an electronic apparatus includes a terminal, an amplifier, a speaker, a power supply circuit and a first controller. The terminal configured to input an audio signal from an external device. The amplifier configured to amplify the audio signal. The speaker configured to output sound corresponding to the audio signal which is amplified by the amplifier. The power supply circuit configured to supply power to the amplifier. The first controller configured to control the power supply circuit to continue the supply of the power, when the electronic apparatus is in a non-operative state.

1 . An electronic apparatus comprising:
 a terminal configured to input an audio signal from an external device;   an amplifier configured to amplify the audio signal;   a speaker configured to output sound corresponding to the audio signal which is amplified by the amplifier;   a power supply circuit configured to supply power to the amplifier; and   a first controller configured to control the power supply circuit to continue the supply of the power when the electronic apparatus is in a non-operative state.   
     
     
         2 . The electronic apparatus of  claim 1 , further comprising:
 a storing module configured to store data indicative of whether audio output is to be permitted or prohibited when the electronic apparatus is in a non-operative state; and   a setting module configured to set the first controller to permit the audio output when the data indicative of permission of the audio output is stored.   
     
     
         3 . The electronic apparatus of  claim 2 , further comprising a switch configured to switch between a first path which connects the terminal and the amplifier and a second path which connects the terminal and the amplifier via a second controller configured to operate when the electronic apparatus is in an operative state,
 wherein the first controller is configured to set the switching module to the first path when the data indicative of permission of the audio output is stored.   
     
     
         4 . The electronic apparatus of  claim 1 , further comprising a volume control configured to adjust amplification of the audio signal by the amplifier. 
     
     
         5 . The electronic apparatus of  claim 2 , further comprising a detection module configured to detect that the audio signal from the external device is input to the terminal,
 wherein the first controller is configured to control the power supply circuit to continue the supply of the power when the audio output is permitted and the detection module detects that the audio signal is input.
