12
be considerably larger than the actual size so that the structure of the sound emitting and
collecting device can be well understood.
[0044]
As shown in FIG. 3, when using the basic configuration without deforming the sound emission
and collection device 1, by arranging a plurality of users around the sound emission and
collection device 1, it is possible to use one to eight people. It can be used by people. In addition,
it can be used by a large number of people by reducing the distance between users. The sound
emission and collection device 1 is cylindrical as described above, and a plurality of sound
emission and collection elements 33-1 to 33-11 are disposed on the inner peripheral surface.
Therefore, for example, by operating the operation unit 19 to alternately cause the sound
emitting and receiving elements 33-1 to 33-11 to function as a speaker and a microphone, the
sound emitting and receiving element 33 functioning as a microphone is particularly a user. And
the sound emitting and receiving element 33 at a position substantially opposite to the sound

At this time, in the case of the automatic setting mode, the control unit 57 of the sound emission
and collection device 1 detects that each of the housings 11 to 17 is not rotated by the rotation
detection units 53 and 55, and each sound emission and collection The elements 33-1 to 33-11
are alternately set to function as a speaker and a microphone. For example, the sound emitting
and collecting elements 33-1, 33-3, 33-5, 33-7, 33-9, and 33-11 function as microphones, and
the remaining sound emitting and collecting elements function as speakers.

[0047]
At this time, in the automatic setting mode, the control unit 57 of the sound emission and
collection device 1 detects that the rotation shaft 25 is rotated 180 degrees by the rotation
detection unit 55B, and the other rotation detection unit 53 The rotation detection unit 55
detects that the other rotation shaft is not rotated. The sound emitting and collecting elements
33-3, 33-4, 33-8, and 33-9 function as microphones, and the other sound emitting and collecting
elements 33 function as speakers. When the sound emitted from the sound emission and
collection element 33 is stereo, for example, the sound emission and collection elements 33-1 to
33-2 emit the sound of the right channel, and the sound emission and collection element 33-5 It
is good to set to emit the sound of the left channel. Since the sound emitting and receiving
elements 33 are attached to the inner circumferential surface, the emitted sound intersects, and
the user U hears the sound of the right channel from the right ear and the sound of the left
channel from the left ear It will be. This makes it possible to efficiently emit and collect sound.

of the sound emission and collection device 1 as a central axis, and the case 17 with respect to
the case 15 with the turning shaft 29 as a central axis. When rotated 180 degrees, as shown in
FIG. 4 (B), it becomes a type which made two S character back to back. In this case, as shown in
FIG. 4B, the sound collection elements 33 respectively provided on the inner peripheral surface
of the housing 11, the inner peripheral surfaces of the housings 13 and 15, and the inner
peripheral surface of the housing 17. By arranging the users at opposite positions, one to three
persons can use the sound emission and collection device 1.

03-05-2019
14
and collection device 1 rotates the rotating shafts 23 and 29 by 180 degrees by the rotation
detecting units 55A and 55C, and rotates the other rotating shafts. Detect that you are not doing.
The sound emitting and collecting elements 33-2, 33-5, 33-6, and 33-10 function as
microphones, and the other sound emitting and collecting elements 33 function as speakers.
[0050]
Furthermore, the case 11 is turned 180 degrees with respect to the case 13 with the turning
shaft 23 of the sound emission and collection device 1 as a central axis, and the case 13 is made
relative to the case 15 with the turning shaft 25 as a central axis. The housing 17 is turned 180
degrees with respect to the housing 15 with the turning shaft 29 as a central axis. By doing this,
as shown in FIG. 5, it becomes a type in which two S-shaped characters are connected at the end.

Therefore, in addition to the modification of the sound emitting and collecting apparatus 1
described in FIGS. 3 to 9, in the sound emitting and collecting apparatus 3, as shown in FIG. 13A,
the housing 13 with the pivot shaft 20 as the central axis. The housing 11 can be rotated relative

shaft 31 as a central axis. In this case, the case 11 is stacked on the case 13 and the case 17 is
deformed in the shape stacked on the case 15, so the position facing the inner peripheral surface
side of each case 11 to 17 By disposing the user at, the sound emission and collection device 1
can be used by one person.
[0076]
At this time, when the automatic setting mode is set, the control unit 57 of the sound emission
and collection device 3 rotates the rotation shaft 20 by 180 degrees by the rotation detection
unit 53D, and the rotation shaft by the rotation detection unit 53C. 31 is turned 180 degrees,

Further, the case 13 is turned 90 degrees with respect to the case 15 with the turning shaft 27 of
the sound emission and collection device 3 as a central axis. Subsequently, from the state where
the right side surface 11R and the left side surface 13L are opposed to each other with respect to
the case 13 with the turning shaft 23 of the sound emission and collection device 3 as a central
axis (30 degrees to 60 degrees). The housing 11 is rotated by 90 degrees with respect to the
housing 13 with the rotation shaft 20 as a central axis while being rotated at an arbitrary angle
of degree. In addition, the case 17 is 30 degrees to 60 degrees from the state where the right
side surface 15R and the left side surface 17L face each other with respect to the case 15 with
the rotation shaft 29 of the sound emission and collection device 1 as a central axis. Rotate to
any angle of. Further, the case 17 is turned 90 degrees with respect to the case 15 with the
turning shaft 31 as a central axis. Thereby, the sound emission and collection device 3 can be
deformed into the shape as shown in FIG. 13 (B).
[0078]
In this case, as shown in FIG. 13B, the user is positioned at the position facing the sound emitting
elements 33 respectively provided on the inner circumferential surface of the housings 11 and
13 and the inner circumferential surface of the housings 15 and 17. By arranging, the sound
emission and collection device 1 can be used by one or two people.
[0079]
At this time, when the automatic setting mode is set, the control unit 57 of the sound emission
and collection device 1 rotates the rotation shaft 27 by 90 degrees by the rotation detection unit
53B, and the rotation shaft by the rotation detection unit 55A. 23 is rotated by an arbitrary angle
of 30 to 60 degrees, the rotation shaft 20 is rotated by 90 degrees by the rotation detection unit

microphones, and the sound collection elements 33-4 to 33-8 of the housings 13 and 15 are set
to function as speakers. .
As a result, the sound emitting and collecting elements 33 provided in the housings 11 and 17
are arranged in a direction substantially perpendicular to the mounting surface of the sound
emitting and collecting device 1, so that the user U moves his face up and down. Even if you
speak, you can pick up the voice efficiently.
[0080]
Next, the movable portion connecting the casings of the sound emission and collection device
may have another configuration. FIG. 14 is a diagram showing still another configuration of the
sound emission and collection device. In the sound emission and collection device 5 shown in
FIG. 14, a ball joint is used as a movable portion connecting the respective housings 11 to 17.
That is, a portion corresponding to the right side surface 11R of the housing 11 and a portion
corresponding to the left side surface 13L of the housing 13 are ball joints 61, a portion
corresponding to the right side surface 13R of the housing 13 and the left surface 15L of the

device 5, the surface (end surface) corresponding to the right side surface 11R of the housing 11
and the left surface 13L of the housing 13 opposite to this surface The housing 11 can be
pivoted relative to the housing 13 about an axis perpendicular to the surface (end surface)
corresponding to. Similarly, the housing 13 is centered on an axis perpendicular to a surface (end
surface) corresponding to the right side surface 13R of the housing 13 and a surface (end
surface) corresponding to the left surface 15L of the housing 15 opposite to this surface. Can be
made rotatable relative to the housing 15. In addition, the housing 15 is centered on an axis that
is vertical to the surface (end surface) corresponding to the right side surface 15R of the housing

peripheral surface 13T, and lower surface 13D of the housing 13, and a portion corresponding to
the left surface 15L and right surface 15R of the upper surface 15U, outer peripheral surface
15T, and lower surface 15D of the housing 15. Are provided with notches 81-89. Thereby, the
housing 11 can be rotated 90 degrees in three directions of the upper surface side, the outer
peripheral surface side, and the lower surface side with respect to the housing 13. Similarly, the
housing 13 can be rotated 90 degrees in three directions with respect to the housing 15, and the
housing 15 can be rotated 90 degrees in three directions with respect to the housing 17.
[0083]
Furthermore, in the sound emission and collection device 5, by using a ball joint for the movable
portion, it is not necessary to provide two axes for the movable portion for rotation.
[0084]
However, since the upper limit (predetermined value) of the pivot angle (swing angle) is 90
degrees as described above, the ball joint has the sound emitting and collecting device 1 and the
sound emitting and collecting device shown in FIGS. It can not be rotated to a state in which the
upper surfaces or the lower surfaces are in contact with each other as in No. 3, that is, 180
degrees.
However, the modifications shown in FIGS. 4 to 6, 8A, and 9 described above can be
implemented.
[0085]

formed by the respective housings 11 to 17 arranged annularly by providing the ball joints 61
and 65. It can be said that the structure is connected rotatably around a central axis.

In addition, the deformed state can be detected by the rotation detection unit, and in accordance
with the state, automatic setting can be performed so that the sound emitting elements 33-1 to
33-11 function as a speaker or a microphone.
[0087]
In the present specification, not all of the modifications of the sound emission and collection
devices 1, 3 and 5 have been described, and other modifications not shown are naturally
possible. In addition, when the automatic setting mode is set, the sound emitting element 33 is
automatically set so as to properly function as a speaker or a microphone even in a modified
example (not shown).

In the above description, although the case where the sound emission and collection device 1 is
composed of four casings having a shape in which the cylinder is divided into four in the radial
direction (four equal parts) has been described, the present invention is not limited thereto. It
may be another shape. That is, any shape can be selected as long as each case can be arranged
annularly with its both end faces in contact with the other case. FIG. 15 is a view showing a
modification of the shape of the sound emission and collection device. For example, as shown in
FIG. 15, the sound emission and collection device 1 may have a shape obtained by dividing a
square tube into four. The part to be divided may be a corner (apex) as shown in FIG. 15 (A) or a
side as shown in FIG. 15 (B). Further, as shown in FIG. 15C, it may be a shape in which a
hexagonal cylinder is divided into six, that is, a shape in which six casings are arranged in an
annular shape with both end surfaces in contact.
