According to one embodiment, an electronic apparatus comprises: a speaker; a sound circuit section that drives the speaker; and a power supply section which is powered by an AC source, which comprises a battery, and which can feed DC power to the sound circuit section by power of the AC source or the battery. When the DC power is fed by the AC source, the power supply section feeds the sound circuit section with a first supply voltage supplied from the DC power. When the DC power is fed by the battery, the power supply section feeds the sound circuit section with a second supply voltage which is supplied from the battery. The second supply voltage is lower than the first supply voltage.
