A voice-controlled power device includes a voice-controlled circuit which includes a power module for getting an AC input voltage, a switch module having an electromagnetic relay and a driving circuit, and a control module having a microcontroller, a power unit regulating an output voltage of the power module and providing a work voltage for the microcontroller, a voice-detecting unit receiving voice signals and transforming the voice signals into electric signals, and a voice-amplifier unit amplifying the electric signals. The microcontroller receives and analyzes the amplified electric signals and sends out control signals to drive the driving circuit to control switch states of the electromagnetic relay and further control whether there is power output to an external electric appliance or not. The switch states of the electromagnetic relay rest with whether the output voltage of the power module is provided thereon or not under the control of the driving circuit. |
