In principle, when the user switches the speaker device 1 to 5.1 channel to match the listening
mode of the large sound field, the sound of the main speaker unit 221 basically moves away
from the partition part 214 along the central axis CA In the interior of the cabinet, the sound of
some of the sub-speaker units 222 flows in two routes and the holes not belonging to those flow
routes are closed.
For example, the sound of one flow route of the secondary speaker unit 222 flows first to the
second channel through hole 23113 of the channel adjustment disc 2311 via the communication
part 2114 of the lid 211. Next, at the same time, it passes through the straight and tunnel-like
sound field replacement through-holes 23122 a and 23122 b of the sound field adjusting disc
2312. Then, the sound passes through the positioning passage openings 23211 of the
positioning ring 2321 and flows from the plurality of sound source output through openings
23222 of the sound source output disk 2322 to the user's ear.
[0071]
10-05-2019
22

first channel through hole 23112 of the channel adjustment disc 2311 via the recessed tank hole
21132 of the arc shaped recessed tank 21131 of the lid 211. Next, at the same time, it passes
through the straight sound field replacement through hole 23122 c of the sound field adjustment
disc 2312. Then, the sound passes through the positioning passage openings 23211 of the
positioning ring 2321 and flows from the plurality of sound source output through openings
23222 of the sound source output disk 2322 to the user's ear.
