Abstract
The utility model provides a sound control device which is installed in a socket or a power control system, wherein the socket or the power control system is connected with a household electrical appliance. The sound control device comprises a sound acquiring module, a signal amplifier, a voltage comparator, a microcontroller, and a power connection-disconnection module. The sound acquiring module reads a sound signal emitted by a household electrical appliance and converts the sound signal into a voltage signal. Having amplified the voltage signal outputted by the sound acquiring module, the signal amplifier outputs real-time voltage. The voltage comparator compares the real-time voltage with preset standard voltage and outputs a compared result. The microcontroller controls the value of the preset standard voltage and outputs a disconnection signal or a connection signal according to the compared result. The power connection-disconnection module maintains disconnection between the household electrical appliance and a power supply if receiving the disconnection signal, and maintains connection between the household electrical appliance and the power supply if receiving the connection signal. The sound control device is capable of reading the sound emitted by the household electrical appliance and cutting off the power of the household electrical appliance if the sound exceeds the standard voltage in order to stop the overloud household electrical appliance from continuously emitting overloud sound.
