Summary:The invention discloses an intelligent sound box with a control circuit. The equipment comprises an MIC circuit, a peripheral interface, a dual-track Bluetooth module, a power circuit, a human-computer interface, an external SD card interface, an external FLASH module, a power amplifier circuit and an FM circuit, wherein an MCU is integrated in the dual-track Bluetooth module, signals collected by an FM in the power amplifier circuit are sorted through the dual-power amplifier circuit and then sent to the MCU, the MIC circuit receives audio signals and outputs the audio signals to the MCU, the MCU sends the processed signals out through the FM or amplifies the processed signals through the power amplifier circuit, and then the processed signals are played through the loudspeaker. By measuring an analog signal of the ADKEY and adjusting a mode, a signal collected by the FM is sorted by the dual-power amplifier circuit and then is sent to the MCU for processing; therefore, the device can control the signal outp
