Audio noise generator

The utility model discloses a audio noise generator, including a white noise generator, which is used to produce white noise signals; a pink noise generator, which is used to produce pink noise signals; a noise synthesis circuit, which can output the synthesis noise signals after the operation of the connection of the white noise signals and the pink noise signals; and a power amplifier circuit. The synthesis noise circuit output is connected with the power amplifier circuit and export interference signals. The utility model can provide better and more effective protection for the speakers.
