the peripheral surface of the circularly cylindrical enclosure 2 listeners who are present around the audio reproducing apparatus 1 listen to their desired sounds with the speaker units 3 a to 3 h for example as shown in fig1 a listener 5 listens to his or her desired sound with the speaker unit 3 b disposed in front of the listeners a listener 6 listens to his or her desired sound with the speaker unit 3 g a listener 7 listens to his or her desired sound with the speaker unit 3 e the positions of the listeners around the audio reproducing apparatus 1 are determined for example by a camera unit 4 disposed therein the camera unit 4 can capture images at 360 degrees in all the directions the audio reproducing apparatus 1 analyzes captured image data to determine the positions of the listeners therearound assuming that the radial direction of the speaker unit 3 a is 0 degrees the position of the listener 5 is defined for example as 315 degrees the position of the listener 6 for example as 90 degrees and the position of the listener 7 for example as 180 degrees instead the speaker units used by the listeners may be determined corresponding to the positions of the listeners in addition the distance from each speaker unit to the corresponding listener may be measured the positions of the listeners and the distances between the listeners and the speaker units may be measured by other than the camera unit 4 for example an ultra sonic wave may be emitted in the radial direction of each speaker unit by detecting a reflection wave from.
