PROBLEM TO BE SOLVED: To provide an audio system for enabling a user to change a directivity in a required direction at required timing even when a required sound source does not exist within a visual field.SOLUTION: An audio system includes: at least a pair of audio devices. Each one of the audio devices includes: communication means for enabling mutual communication; utterance state identification means for identifying the utterance state of a wearer; device position detection means for detecting the position and direction of an audio device of a communication partner; directivity sound acquisition means for arbitrarily adjusting a directivity; directivity sound output means for arbitrarily adjusting the directivity; and directivity adjustment means for adjusting each directivity. When the utterance state identification means identifies an utterance state, the existence of the utterance state is exchanged between the devices. The audio device that has transmitted the utterance state controls the directivity of the sound output means to the detection position of the position detection means. The audio device that has received the utterance state controls the directivity of the sound acquisition means to the detection position of the position detection means.SELECTED DRAWING: Figure 1 |
