摘要
An apparatus for adjusting sound volume for an audio system includes a controller (101) connected to an amplifier (40) of the audio system, an audio processor (104), a circuit (102) for adjusting sound volume, and a communication port (103). The controller controls the amplification of the amplifier through the communication port. The circuit includes an adjustor (1022) connected to the audio processor, and a switch (1024) coupled to the audio processor. The controller controls the switch to switch an operating mode of the circuit between a normal mode and an attenuation mode. The adjustor is coupled to the switch. In the normal mode, the switch directly transmits unadjusted audio signals to the audio processor. In the attenuation mode, the audio processor controls the adjustor to output unadjusted audio signals or attenuated audio signals. A related method for adjusting sound volume for an audio system is also disclosed.
