Abstract
A switch circuit includes a first audio input pin configured to receive a first audio signal having a first amplitude, a second audio input pin configured to receive a second audio signal having a second amplitude, an input pin, an output pin, and at least one switch configured to convert the input voltage to the output voltage. When a maximum of the first amplitude and the second amplitude is lower than a first threshold voltage, the output voltage is a default voltage. When the maximum of the first amplitude and the second amplitude is greater than the first threshold voltage but lower a second threshold voltage that is greater than the first threshold voltage, the output voltage is a first voltage greater. When the maximum of the first amplitude and the second amplitude is larger than the second threshold voltage, the output voltage is a second voltage.
