sound designated state in the designated direction 120b. In addition, with regard to the halfway
participation of the participant 4d, the participant 4a presses the direction button 12j, and newly
sets the sound collection and sound designation state in the designated direction 120j. In
addition, the participant 4 may operate the operation unit 11 to change the sound collection and
collection destination. In addition, the moved participant 4a may not necessarily instruct by
pressing the direction button 12.
[0054]
From the above, in the sound emission and collection device 1 of the present embodiment, the
participant 4 simply presses the direction button 12 corresponding to the designated direction in
which the sound collection and release is desired, and the new setting and change of the sound

Second Embodiment Next, a second embodiment of the present invention will be described with
reference to FIGS. The second embodiment is different from the first embodiment in that the
remote controller 5 also has a direction instructing unit 201 in addition to the direction
instructing unit 20 of the sound emission and collection device 1 main body. FIG. 6A is a diagram
illustrating a meeting between remote places using the sound emission and collection device 1
and the remote control 5. FIG. 6B is an explanatory view of the remote control 5. FIG. 7 is a block
diagram showing the sound emitting and collecting function of the sound emitting and collecting
device 1 and the remote controller 5. In the present embodiment, the execution mode of the
sound emission and collection device 1 is shown for the case of the sound emission and
collection mode in which the sound collection and collection destination is specified by the
direction instructing unit 20 and 201, but the invention is not limited thereto. A sound emission
mode in which only the sound emission destination is specified at this time, and a sound
collection mode in which only the sound collection destination is specified by the direction
instructing section 20, 201 may be used.
[0056]
In FIG. 6A, the sound emission and collection device 1 installed in the conference room is
connected to a sound emission and collection device (not shown) installed at a remote place via
the Internet 3. The sound emitting and collecting device 1 determines the sound emitting and
collecting destination by the operation of the operation unit 11 and the direction instructing unit
20 of the sound emitting and collecting device 1 and the operation of the remote controller 5 by
the participants 4 (4a to 4d). The number of remote controls 5 may be one jointly or plural.
[0057]
The remote controller 5 in FIG. 6B includes a signal transmission unit 51 and an azimuth
instructing unit 201. The azimuth instructing unit 201 includes an azimuth button 52 (52a to
52j) and an omnidirectional sound pickup stop button 53. When the various buttons 52 and 53
04-05-2019
18
are pressed, the signal transmission unit 51 transmits a signal including the content of the
operation input (e.g., the sound collection destination Dir 2 or the like) to the sound emission and
collection device 1.
[0058]
The direction button 52 (52a to 52j) has the same function as the direction button 12 (12a to
12j) of the sound emission and collection device 1. When the direction button 52b is pressed, the
sound emission and collection device 1 enables sound emission toward the participant 4a as in
the case where the direction button 12b is pressed.
[0059]
The omnidirectional sound pickup stop button 53 has the same function as the omnidirectional
sound pickup stop button 13 of the sound emission and collection device 1. When the
omnidirectional sound collection stop button 53 is pressed, the sound emission and collection
device 1 stops sound collection from all directions, and emits sound in a designated direction
corresponding to the direction button 12 set in the collected sound designation state. When the
omnidirectional sound collection stop button 53 is pressed again, sound collection from the
direction corresponding to the direction button 12 set to the collected sound specification state is
started, and the sound is collected in the corresponding specified direction.
[0060]
As shown in FIG. 7, the remote control 5 transmits the operation input content (such as the
sound collection and collection destination Dir 2) of the remote control 5 to the direction control
unit 22 of the collection and collection device 1. When the direction control unit 22 receives the
operation input content (e.g., sound collection destination Dir2) from the remote control 5, the
direction control unit 22 receives the operation input content (e.g. Direction signal (DS) for
specifying the sound collection destination of each of the microphones 16a to 16p and 17a to
17p, and outputs the direction signal (DS) to the voice control unit 23. In the present
embodiment, the remote controller 5 only has the function of the direction instructing unit 201,
but the function of the operation unit 11 may be added.

As described above, in the sound emission and collection device 1 of the present embodiment,
the participant 4 operates the remote control 5 without directly operating the sound emission
and collection device 1, thereby allowing the sound emission and collection destination of the
sound emission and collection device 1 to be It can be specified. For this reason, the participant 4
can designate the sound collection destination on the spot without standing up the seat.
