Abstract: This disclosure relates to a signal generating circuit and an audio processing device. The circuit includes a switch module, a voltage producing module, and a signal generating module; the switch module is connected to the voltage producing module, including at least one control switch, and is used for receiving a frequency division signal. Based on the frequency division signal, the at least one control switch is turned on or turned off; the voltage producing module is separately connected to the switch module and the signal generating module and used for producing a first voltage and a second voltage. The at least one control switch controls the first voltage and the second voltage to change. The signal generating module is connected to the voltage producing module and used for generating a carrier signal with the same frequency as the frequency division signal according to the received first and second voltages.
