PROBLEM TO BE SOLVED: To provide an audio system, and a method for measuring the coordinate position of a speaker module, capable of providing an optimal acoustic field with a small scale.SOLUTION: Each speaker module 1LF-2RF includes: a speaker unit; a microphone 11 for collecting a test tone; and a first transmission/reception unit for transmitting a sound collection signal to an audio device 3 side through a single transmission line, and for supplying to speakers 12, 13 the audio signal transmitted from the audio device side through the transmission line. The audio device includes: a test tone generator unit for generating a test signal having a frequency within a speaker band; second transmission/reception units 30a-30d for selectively transmitting the test signal and the audio signal through transmission lines 4a-4d to the speaker module, and for receiving the sound collection signal through the transmission lines; and a speaker coordinate analysis unit 33 for obtaining a three-dimensional coordinate position of each speaker module based on the received sound collection signal. |
