Abstract
An audio system to calibrate an audio signal based on a wirelessly received signal, and a signal calibration method are provided. The audio system includes a sound output unit to output a sound corresponding to a received audio signal. A transceiver is connected to an external device to enable wireless communication between a main unit and the external device. The external device converts the sound output from the sound output unit into an electric signal to generate a calibration audio signal. The main unit performs calibration on an audio signal to be played back through the sound output unit using the calibration audio signal.
Claims48
