[0003]
For example, Patent Document 1 discloses a two-way communication device in which voices from
the angular direction of the horizontal surface are picked up by arranging the microphones
radially in the horizontal direction, and the horizontal sound is emitted by the speaker and the
reflector. ing.
[0004]
However, in such a two-way communication device, when a small group of two to four people
hold a conference in a small room, the voice from each conference person is collected at a high
level, Although it is possible to emit a predetermined level of sound to the conferees, in a large
room, when more conferees hold a conference, the sound collection level for each conferee
becomes very low, or each conferee Can not do enough noise emission.
[0005]
For this reason, an audio conference system used when conducting a conference in a large space
such as a large conference room or conference hall as shown in FIG. 6 has been put to practical
use.
