发明名称 ELECTRONIC DEVICE
摘要 Provided is an electronic device which can prevent operation stop attributed to lowering of an electronic device operation voltage. A pre-stage of a power amplifier (24) is connected to a capacitor and a first and a second current limit circuit. A CPU (21) monitors a voltage of the capacitor and corrects a gain of the power amplifier (24) in accordance with the voltage value. Moreover, when the electronic device includes a speaker system having a plurality of channels, an audio signal reproduction mode is switched, for example, between a stereo reproduction and a monaural reproduction according to the voltage value of the capacitor.
