rises with the left end of the bar graph display area 414S as the origin and the left (X axis as the
volume value falls) Shrink in the negative direction).
[0066]
The slider display area 417S covers the entire bar graph display area 414S, and the slider 418S
is displayed at the position corresponding to the volume value or the user's operation at that
time.
[0067]
The slider 418S is for raising and lowering the volume value by the slide operation.
In FIG. 4, the slider 418S is disposed to overlap the right end of the bar graph 415S.
The slide operation of the user can move the slider 418S to the right and left along the X axis.
When the slider 418S is moved to the right, the volume value increases, and when the slider

operation contents.
[0069]
The individual control display areas 412A, 412B, and 412C correspond to the audio devices 3A,
3B, and 3C, respectively. The display of the individual control display areas 412A, 412B, and
412C is common to the display of the synchronization control display area 412S, and thus
detailed description will be omitted.
[0070]
Next, with reference to FIGS. 5 to 7, control for uniformly (synchronizing) or individually raising
and lowering the volume values of the audio devices 3A, 3B, and 3C by the controller 100
according to the present embodiment will be described.
[0071]
First, with reference to FIG. 5, the case where the volume values of the audio devices 3A, 3B, and
3C are uniformly controlled by synchronous control will be described.
FIG. 5 shows an example of the operation of increasing the volume value by sliding the slider
418S, which is the interlocking operated portion in the synchronization control display area
412S, to the right along the X axis.
[0072]
In FIG. 5, the slider 418S moves in the volume rising direction (rightward) along with the slide
operation by the user's finger F, and the bar graph 415S also extends in the volume rising
direction as the slider 418S moves. The movement amount of the slider 418S in the volume
rising direction is represented by VS1.
[0073]
09-05-2019
20
As the slider 418S moves in the volume rising direction (rightward), the sliders 418A, 418B, and
418C, which are individually operated portions of the individual control display areas 412A,
412B, and 412C, also move in the volume rising direction (rightward). Move uniformly. Assuming
that the moving amounts of the sliders 418A, 418B and 418C are VA1, VB1 and VC1,
respectively, VA1, VB1 and VC1 are equal to the moving amount VS1 of the slider 418S (VA1 =
VB1 = VC1 = VS1). That is, the movement of the sliders 418A, 418B, and 418C, which are the
individual operated portions, is interlocked with the movement of the slider 418S, which is the
interlocked operated portion. In addition, the bar graphs 415A, 415B, and 415C also extend in
the volume upward direction as the sliders 418A, 418B, and 418C move.
[0074]
When the user finishes the slide operation on the slider 418S, the synchronization control of the
volume value ends. The volume values of the audio devices 3A, 3B, and 3C are determined when
the operation of the slider 418S is stopped.
[0075]
As described above, by operating the slider 418S, which is the interlocking operated portion, the
volume values of the audio devices 3A, 3B, and 3C connected to the network can be uniformly
controlled.
[0076]
Next, with reference to FIG. 6, the case of individually controlling the volume value of the audio
device 3A which is the master device will be described.
FIG. 6 illustrates an example of the operation of sliding the slider 418A, which is an individual
operated portion, rightward along the X axis to increase the volume value of the audio device 3A.
[0077]
09-05-2019
21
In FIG. 6, the slider 418A moves in the volume rising direction (rightward) along with the slide
operation by the user's finger F, and the bar graph 415A also extends in the volume rising
direction as the slider 418A moves. The movement amount of the slider 418A in the volume
rising direction is denoted by VA2.
[0078]
As the slider 418A moves in the volume ascending direction (rightward), the slider 418S which is
the interlocking operated portion also moves in the volume ascending direction (rightward).
Assuming that the moving amount of the slider 418S is VS2, the moving amount VS2 is equal to
the moving amount VA2 of the slider 418A (VA2 = VS2). In addition, the bar graph 415S also
extends in the volume increasing direction as the slider 418S moves.
[0079]
That is, the volume value of the audio device 3A, which is the master device, rises corresponding
to the amount of movement of the slider 418A and the graph 415A. Further, when the slider
418A corresponding to the master device is operated, the slider 418S which is the interlocking
operated portion also moves in the volume rising direction (rightward) by the same moving
amount as the slider 418A.
[0080]
When the user finishes the slide operation on the slider 418A, the individual control of the
volume value of the audio device 3A ends. The volume value of the audio device 3A is
determined when the operation of the slider 418A is stopped.
[0081]
Thus, by operating the slider 418A, which is an individual operated portion, the volume value of
the corresponding audio device 3A among the audio devices 3A, 3B, and 3C connected to the
network can be individually controlled. . Therefore, only the volume value of the audio device 3A
can be adjusted.
09-05-2019
22
[0082]
Further, when the slider 418A corresponding to the audio device 3A which is the master device
is operated, the slider 418S which is the interlocked operated portion moves following the slider
418A. Therefore, the position of the slider 418A of the master device and the slider 418S for
synchronous control can be made to coincide with each other.
[0083]
Next, with reference to FIG. 7, the case of individually controlling the volume value of the audio
device 3B which is the slave device will be described. FIG. 7 shows an example of the operation of
sliding the slider 418B, which is an individual operated portion, rightward along the X-axis to
increase the volume value of the audio device 3B.
[0084]
In FIG. 7, the slider 418B moves in the volume rising direction (rightward) in response to the
user's slide operation, and the bar graph 415B also extends in the volume rising direction as the
slider 418B moves. The moving amount of the slider 418B in the volume rising direction is VB3.
[0085]
The other sliders 418S, 418A and 418C do not move even if the slider 418B is moved in the
volume rising direction (rightward).
[0086]
That is, although the volume value of the audio device 3B which is a slave device rises
corresponding to the movement amount of the slider 418B and the graph 415B, the other sliders
418S, 418A and 418C do not move, and the audio devices 3A and 3C are not moved. Volume
value does not change.
[0087]
09-05-2019
23
When the user ends the slide operation on the slider 418B, the individual control of the volume
value of the audio device 3B ends.
The volume value of the audio device 3B is determined when the operation of the slider 418B is
stopped.
[0088]
Thus, the volume value of the audio device 3B corresponding to the slider 418B is individually
controlled among the audio devices 3A, 3B, and 3C connected to the network by operating the
slider 418B which is an individual operated portion. be able to.
Therefore, only the volume value of the audio device 3B can be adjusted.
[0089]
Further, even if the slider 418B corresponding to the audio device 3B which is a slave device is
operated, the slider 418S which is the interlocking operated portion and the sliders 418A and
418C corresponding to the audio devices 3A and 3C do not move. Therefore, the relative
relationship between the volume values of the audio devices 3A, 3B, and 3C constituting the
synchronous reproduction group can be changed.
[0090]
Although a detailed description is omitted, when the slider 418C corresponding to the audio
device 3C which is a slave device is operated, only the volume value of the audio device 3C is
controlled, and the other sliders 418S, 418A and 418B move. do not do.
[0091]
When the volume value of the audio device is increased or decreased by the operation of the
slider 418 (418S, 418A, 418B, 418C), the change of the volume value is transmitted to the
corresponding audio device as a command message by the message editing and transmitting unit
