Abstract
An electronic device includes two speakers, a single functional chip, a parameter extraction circuit, an audio processing module, a gain adjusting circuit and a current detecting unit. The current detecting unit is disposed in the functional chip for detecting the driving current of the two speakers. The functional chip provides the driving voltage of the two speakers based on an output signal and converts the analogue current/voltages of the two speakers into digital current/voltages. The parameter extraction circuit acquires the parameter of each speaker based on the digital current/voltages. The audio processing module acquires the gains of various physical quantities based on the parameter of each speaker and determines the final gain of each physical quantity. The gain adjusting circuit provides the output signal by adjusting the gain of an input signal based on the final gain of each physical quantity.
