Abstract:
1. An audio driving apparatus, comprising: a first driving circuit, receiving a first audio signal pair and generating a first driving signal according to the first audio signal pair; a second driving circuit, receiving a second audio signal pair and generating a second driving signal according to the second audio signal pair; a signal transmitting circuit, having a first output end pair and a second output end pair, the signal transmitting circuit receiving the first and second audio signal pairs and a reference signal, the signal transmitting circuit transmitting the first audio signal pair or the reference signal to the first output end pair according to a mode selecting signal, and the signal transmitting circuit deciding to transmit the second audio signal pairs to the second output end pair or not according to the mode selecting signal; a first reference signal generator, coupled to the first output end pair of the signal transmitting circuit for receiving signals on the first output end pair and generating a first reference signal; and a second reference signal generator, coupled to the second output end pair of the signal transmitting circuit for receiving signals on the second output end pair and generating a second reference signal, wherein, the first and second reference signal generators are turned off according to the mode selecting signal.
