Acoustic device, acoustic setting method and acoustic setting program
[0001]
The present invention relates to an audio apparatus, an audio setting method, and an audio
setting program, and is suitably applied to, for example, a multi-channel speaker system.
[0002]
Conventionally, in an audio visual system (hereinafter referred to as an AV system) in which an
audio system such as an audio amplifier having a multi-channel reproduction function or a
receiver having a tuner function is provided with an image reproduction function. The speaker
setting for each speaker is always required as an initial setting.

[0003]
As an AV system having a general multi-channel reproduction function, for example, a left front
speaker FL, a right front speaker FR, a center speaker CT, a left surround speaker SL, a right
corresponding to the audio format of DVD video being 5.1 ch There is a 5.1 ch speaker system
which consists of surround speaker SR and subwoofer SW (for example, refer to patent
documents 1).
[0004]
In recent years, there is also a 6.1ch AV system equipped with a surround back speaker
compatible with 6.1ch playback output, such as DOLBY DIGITAL EX (trademark) and dts-ES
(trademark), as standard equipment. There are an increasing number of 7.1ch speaker systems
with two back speakers and 9.1ch speaker systems with four surround speakers.
[0005]
In an AV system compatible with this type of multi-channel, there is a speaker presence /
absence, large (full band reproduction speaker) / small (medium / high band reproduction
speaker), etc. with respect to a plurality of speakers actually connected. If you do not set each
item, you can not build an optimal multi-channel playback environment, so many speakers are
required to have a speaker setting function.
JP 2005-12534 A
[0006]
By the way, in the AV system having such a configuration, when setting the speakers for each
speaker, the setting state is determined for each of the speakers disposed in the sound field
space, so many items need to be set one by one. In addition, there is a problem that the user is
forced to perform a very complicated operation.
[0007]
Also, in the AV system, as the number of channels increases, the speaker setting items and
setting patterns also increase, as in 2ch <5.1ch <6.1ch <7.1ch.

Usually, in an AV system, only a FL (Fluorescent Lamp) tube with poor display capability is often
used as a user interface provided in audio equipment such as an audio amplifier, and the user is
allowed to set many items as described above The setting operation was complicated, and it was
not an operation environment that anyone could easily set and operate.
[0009]
The present invention has been made in consideration of the above points, and an object of the
present invention is to propose an audio apparatus, an audio setting method, and an audio
setting program that can perform setting operations on a plurality of speakers more easily.
[0010]
In order to solve such problems, the present invention is an audio apparatus in which a plurality
of speakers corresponding to multi-channels are connected, and the speaker setting unit
individually performs individual speaker settings for the plurality of speakers, and the speakers
By providing graphical user interface means for visually displaying on the display unit the
relationship between the arrangement states of the plurality of speakers set by the setting means
and the speaker setting contents of the plurality of speakers, the plurality of speakers can be
displayed. Since the user can visually recognize the arrangement and the speaker setting
contents for each speaker, setting operations for a plurality of speakers can be easily performed.
[0011]
According to the present invention, the arrangement for a plurality of speakers and the speaker
setting content for each speaker can be visually recognized by the user, so that setting operations
for a plurality of speakers can be easily performed. It is possible to realize an audio device, an
audio setting method, and an audio setting program that can perform setting operation on the
speaker more easily.

[0128]
(4-3) Manual Sound Field Setting Method Using GUI Next, a manual sound field setting method
using GUI will be described.
In practice, the control unit 10 of the home server 2 generates the home screen HM (FIG. 3) by
the graphic processing unit 15 and displays the same on the LCD 5 when the power is turned on.
10-05-2019
29
[0129]
The control unit 10 of the home server 2 performs the auto calibration top screen in response to
the selection and determination of the “setting” icon AC3 of the home screen HM (FIG. 3) and
the “auto calibration” icon AC4 in the lower hierarchy thereof. The CT (FIG. 7) is displayed on
the LCD 5.
[0130]
When "measure" icon ACM on this auto calibration top screen CT (FIG. 7) is selected, control unit
10 generates position selection screen PS as shown in FIG. Display on
[0131]
Then, when the position icon ACP on the position selection screen PS (FIG. 33) is selected and
determined, the control unit 10 displays a manual setting editing screen MSE as shown in FIG. 34
on the LCD 5, and the manual setting editing screen MSE (FIG. When the “manual setting” icon
ACM in FIG. 34) is selected and determined, as shown in FIGS. 35 to 39, any one of the speaker
selection screens SS1 to SS5 three-dimensionally generated by the graphic processing unit 15 is
displayed on the LCD 5 It is made to be displayed.
[0132]
The speaker selection screen SS1 (FIG. 35) visually shows that the left front speaker 4FL
subjected to the shading processing is currently selected as a manual setting target.
The speaker selection screen SS2 (FIG. 36) visually shows that the subwoofer 4SW subjected to
the hatching processing is currently selected as a manual setting target.
[0133]
Similarly, the speaker selection screen SS3 (FIG. 37) visually shows that the center speaker 4CT
subjected to the shading processing is currently selected as a manual setting target, and the
speaker selection screen SS4 (FIG. 38) A visual indication that the left surround speaker 4SL
subjected to the shading process is currently selected as a manual setting target, and the speaker
selection screen SS5 (FIG. 39) is a left surround back speaker 4SBL subjected to the shading
process. Visually indicates that is currently selected for manual setting.
10-05-2019
30
[0134]
These speaker selection screens SS1 to SS5 (FIG. 35 to FIG. 39) are mutually switched according
to the user's operation on the “←” key, “→” key, “↑” key and “「 ”key of the remote
controller RCL. As a result, the user can arbitrarily select speaker selection screens SS1 to SS5
(FIGS. 35 to 39) corresponding to the desired speaker 4 as a manual setting target.
[0135]
For example, when the controller 10 recognizes that the "enter" key of the remote controller RCL
has been pressed while displaying the speaker selection screen SS1 (FIG. 35), as shown in FIG. A
speaker level screen showing, as a relative value, the volume level (+3 dB) of the left front
speaker 4FL targeted for manual setting subjected to shading processing as well as the mutual
positional relationship of the speakers 4 as compared to other speakers 4 The SLV 1 is generated
by the graphic processing unit 15 and displayed on the LCD 5.
[0136]
On the speaker level screen SLV1 (FIG. 40), the relative positional relationship between the
speakers 4 when the sound field space is viewed from directly above from the three-dimensional
display of the speaker selection screen SS1 (FIG. 35) immediately before that It is a result of
switching to the dimensional display, and the speaker selection screen SS1 (FIG. 35) can be
presented so that the relative positional relationship of the speakers 4 that is difficult for the user
to understand can be easily understood from directly above.
[0137]
Incidentally, the control unit 10 can present setting contents for the left front speaker 4FL to be
manually set via the setting contents presentation frame FC provided at the lower side of the
screen of the speaker level screen SLV1 (FIG. 40). .
[0138]
Specifically, in the setting content presentation frame FC, the volume level (Level: +3.0 dB), the
left front speaker 4FL, and the listening point LP1 defined as “Position 1” of the listening
position selection screen LPS (FIG. 8). The speaker distance (Distance: 2.7 m) and the speaker
size (Size: Large) are displayed as setting contents for the left front speaker 4FL.
[0139]
10-05-2019
31
In this case, the control unit 10 displays the volume level of the left front speaker 4FL in the
speaker level screen SLV1 (FIG. 40) as a numerical value of “+3 dB” and displays it as a level
mark MK1 indicating the volume level as a visual image When the volume level of the left front
speaker 4FL is changed by the up key UPK or the down key DWK of the setting content
presentation frame FC, the numerical value of the volume level and the level mark MK1 are
displayed while being increased or decreased.
[0140]
As a result, the control unit 10 can make the user intuitively recognize the change of the volume
level with respect to the left front speaker 4FL not only as a numerical value but also by the level
mark MK1.
[0141]
The control unit 10 is shown by broken lines other than the left front speaker 4FL in the speaker
level screen SLV1 (FIG. 40), whereby the mutual positional relationship between the left front
speaker 4FL to be manually set and the other speakers 4 is shown. While showing it, the user can
easily recognize that the manual setting target currently focused on is the left front speaker 4FL.
[0142]
Then, when the control unit 10 recognizes that the “→” key of the remote controller RCL has
been pressed while displaying the speaker level screen SLV1 (FIG. 40) on the LCD 5, as shown in
FIG. The speaker distance screen SDM generated by the above is displayed on the LCD 5.
[0143]

front speaker 4FL to be manually set and the listening point LP1 subjected to shading processing
is displayed.
[0144]
Also in this case, the control unit 10 connects the left front speaker 4FL and the listening point
LP1 by a straight line, and displays the distance (2.7 m) between the left front speaker 4FL and
the listening point LP1 in the vicinity of the straight line. The comparison between the distance
between the other speaker 4 and the listening point LP1 shown by a broken line is intuitively and
numerically expressed.

[0145]
Then, when the control unit 10 recognizes that the “→” key of the remote controller RCL has
been pressed while displaying the speaker distance screen SDM (FIG. 41) on the LCD 5, as shown
in FIG. The speaker size screen SSZ1 generated by the above is displayed on the LCD 5.
[0146]
In the speaker size screen SSZ1 (FIG. 42), when changing the speaker size of the left front
speaker 4FL to be manually set, it is necessary to make the speaker sizes of the right front
speaker 4FR equal, so in this case, the left front speaker 4FL and Both right front speakers 4FR
are shaded.
[0147]
Here, the speaker size means that the large is the full range reproduction speaker, and the small
is the medium and high band reproduction speaker, and the control unit 10 switches the left
front speaker 4FL and the right front speaker 4FR to large or small. It is made to get.
[0148]
In this case, the control unit 10 selects the “↑” key or “↓” of the remote controller RCL in
accordance with the UP key UPK or DOWN key DWK provided in the display portion of the
speaker size (Size: Large) in the setting content presentation frame FC. When recognizing that the
key is depressed, the speaker size of the left front speaker 4FL and the right front speaker 4FR is
switched to "large" or "small".
[0149]
That is, when the control unit 10 recognizes that the “↓” key of the remote controller RCL has
been pressed in accordance with the down key DWK, the speaker size (Size: Large) in the setting
content presentation frame FC of the speaker size screen SSZ1 The display is changed to "small",
and as shown in FIG. 43, the display of the LCD 5 is switched to the speaker size screen SSZ2
generated by the graphic processing unit 15.
[0150]
In this case, in the speaker size screen SSZ2 (FIG. 43), the speaker size of the left front speaker
4FL and the right front speaker 4FR is displayed as an image switched to "small", and the speaker
in the setting content presentation frame FC Even without looking at the display portion of the
size (size: small), it is possible to intuitively recognize that the speaker size is "small".
10-05-2019
33
[0151]
Similarly, as shown in FIG. 44, when the control unit 10 recognizes that the “enter” key of the
remote controller RCL has been pressed while, for example, the speaker selection screen SS4
(FIG. 38) is displayed. A speaker level indicating, as a relative value, the volume level (+5 dB) of
the left surround speaker 4SL subject to manual setting subjected to the shading processing as
well as the mutual positional relationship between the speakers 4 as compared with the other
speakers 4 The screen SLV 2 is generated by the graphic processing unit 15 and displayed on the
LCD 5.
[0152]
Also in this speaker level screen SLV2 (FIG. 44), the relative positional relationship between the
speakers 4 when the sound field space is viewed from directly above from the three-dimensional
display of the speaker selection screen SS4 (FIG. 38) immediately before that is shown. It is
displayed as a result of switching to the two-dimensional display, and in the speaker selection
screen SS4 (FIG. 38), the mutual positional relationship of the speakers 4 which is difficult for the
user to understand is presented in an easily understandable manner from directly above.
[0153]
Incidentally, the control unit 10 is configured to be able to present the setting content for the left
surround speaker 4SL to be manually set via the setting content presentation frame FC provided
at the lower side of the screen of the speaker level screen SLV2 (FIG. 44). Loudspeaker distance
(Distance: 2.7 m) between the left surround speaker 4SL and the listening point LP1 defined as
"Position 1" of the listening position selection screen LPS (FIG. 8) , And speaker size (Size: Small)
are displayed.
[0154]
Also in this case, the control unit 10 displays the volume level of the left surround speaker 4SL in
the speaker level screen SLV2 (FIG. 44) as a numerical value of "+5 dB" and displays it as a level
mark MK2 indicating the volume level as a visual image And when it is recognized that the
volume level of the left surround speaker 4SL is adjusted to the up key UPK or the down key
DWK and the “「 ”key or the“ ↓ ”key of the remote controller RCL is pressed, The level
mark MK2 can be displayed while being increased or decreased.

[0158]
In this speaker height selection screen SHS1 (FIG. 45), when changing the speaker height of the
left surround speaker 4SL to be manually set, the speaker height of the right surround speaker
4SR must necessarily be the same. Both the left surround speaker 4SL and the right surround
speaker 4SR are shaded.
[0159]
Here, the speaker height is a reference for positioning whether the sound image of the sound
output from the left surround speaker 4SL and the right surround speaker 4SR is localized
upward (high) or downward (low). The sound image localization of the left surround speaker 4SL
and the right surround speaker 4SR can be switched to High or Low.
[0160]
Therefore, in the speaker height selection screen SHS1 (FIG. 45), the left surround speaker 4SL
and the right surround speaker 4SR with focus are shown by solid lines, and “Position: Side in
the setting content presentation frame FC provided below the screen. “Low” indicates that the
left surround speaker 4SL and the right surround speaker 4SR are located at the lower side

step SP27 and ends the process.
[0180]
(4-5) Manual Sound Field Setting Processing Procedure by Speaker Pattern Using GUI Next, in
the home server 2, as described above, in addition to performing the manual setting processing
of the speaker 4 for each channel, this AV system The sound field characteristics of the sound
field space can be easily set by the speaker pattern by selecting one of the speaker patterns such
as 2ch, 4ch, 5.1ch, 6.1ch, 7.1ch, 9.1ch, etc. The manual sound field setting processing procedure
will be described.
[0181]
As shown in FIG. 51, the control unit 10 of the home server 2 enters from the start step of the
routine RT3 in accordance with the sound setting program which is an application program, and
proceeds to the next step SP31 to select “Auto” on the home screen HM (FIG. 3). In response
to the “calibration” icon AC4 being selected and determined, the display of the LCD 5 is
switched from the home screen HM to the auto calibration top screen CT (FIG. 7), and the
process proceeds to the next step SP32.
[0182]
In step SP32, the control unit 10 performs speaker selection screens SS1 to SS5 (FIG. 35) from
the auto calibration top screen CT (FIG. 7) through the position selection screen PS (FIG. 33) and
the manual setting editing screen MSE (FIG. 34). 39) is displayed on the LCD 5, and the process
10-05-2019
39
proceeds to the next step SP33.
[0183]
In step SP33, the control unit 10 determines whether or not the speaker selection screens SS1 to
SS5 (FIGS. 35 to 39) corresponding to the speaker 4 for which the user desires manual setting is
selected and determined, and an affirmative result is obtained. , And move on to the next step
SP34.
[0184]
In step SP34, for example, when the speaker selection screen SS1 (FIG. 35) is selected and
determined in step SP33, the speaker level screen SLV1 (FIG. 40), the speaker distance screen
SDM (FIG. 41), the speaker size screen SSZ1 (FIG. 42) and any one of the speaker size screens
SSZ2 (FIG. 43) is displayed on the LCD 5 as a speaker setting list screen, and the process
proceeds to the next step SP35.
[0185]
As described above, in step SP34, a speaker setting list screen corresponding to any one of the
speaker selection screens SS1 to SS5 (FIGS. 35 to 39) selected by the user is displayed on the
LCD 5.
[0186]
In step SP35, the control unit 10 determines whether or not the manual setting operation by the
user via the speaker setting list screen displayed in step SP34 is completed, and when a negative
result is obtained, the process returns to step SP32 and While the process is repeated, when a
positive result is obtained, the process proceeds to the next step SP36.
[0187]
In step SP36, the control unit 10 ends the manual setting process, returns the display of the LCD
5 to the above-described auto calibration top screen CT (FIG. 7), and then proceeds to the next
step SP42 and ends the process.
[0188]
On the other hand, if a negative result is obtained in step SP33, the control unit 10 proceeds to
10-05-2019
40
the next step SP37, and determines whether or not the "option" key of the remote controller RCL
has been selected.
Here, if a negative result is obtained, the control unit 10 returns to step SP32 and repeats the
above-described processing, whereas if a positive result is obtained, the control unit 10 proceeds
to the next step SP38.
[0189]
As shown in FIG. 52, when the controller 10 recognizes that the “option” key of the remote
controller RCL is selected and determined during display of the auto calibration top screen CT
(FIG. 7) in step SP38, as shown in FIG. The option item selection screen OIS generated by step 15
is displayed on the LCD 5, and the process proceeds to the next step SP39.
[0190]
In step SP39, control unit 10 determines whether or not the speaker pattern item ITM is selected
and determined in option item column AR1 of option item selection screen OIS (FIG. 52), and if a
negative result is obtained, next step SP36 Then, the display of the LCD 5 is returned to the
above-mentioned auto calibration top screen CT (FIG. 7) without selecting the speaker pattern
item ITM as an option of manual setting, and then the process proceeds to the next step SP42
finish.
[0191]
On the other hand, if a positive result is obtained in step SP39, the control unit 10 proceeds to
the next step SP40, and in response to the selection of the speaker pattern item ITM, as shown in
FIG. The generated speaker pattern selection display screen SPSD is displayed on the LCD 5, and
the process proceeds to the next step SP41.
[0192]
The speaker pattern selection display screen SPSD (FIG. 53) is provided with a speaker pattern
selection field AR2 in which a plurality of types of speaker patterns are shown as selection items,
and the operation for the “↑” key or the “↓” key of the remote controller RCL. Thus, when
the focus is placed on, for example, the 7.1 channel speaker pattern icon AC20, the 7.1 channel
loudspeaker arrangement state corresponding to the speaker pattern icon AC20 is displayed as a
visual image.
10-05-2019
41
[0193]
Therefore, if the user visually confirms the speaker pattern selection display screen SPSD (FIG.
53), the user can confirm what kind of speaker pattern he or she has selected by the character
display of the speaker pattern icon AC20 and also as a visual image. It is designed to be
intuitively recognized by the expressed 7.1ch speaker arrangement state.
[0194]
The control unit 10 “enters” the remote controller RCL in a state in which the speaker pattern
icon AC20 desired by the user, for example, 7.1 ch is focused from the speaker pattern selection
field AR2 in the speaker pattern selection display screen SPSD (FIG. 53) When it is recognized
that the key has been pressed, the 7.1ch speaker system corresponding to the speaker pattern
icon AC20 is set.
[0195]
In step SP41, the control unit 10 determines whether or not the setting of the speaker pattern in
the sound space has been completed. If a negative result is obtained, the process returns to step
SP40 and repeats the above-described processing, while the positive result is Once obtained, the
process proceeds to the next step SP36.
[0196]
In step SP36, the control unit 10 ends the manual setting process using the speaker pattern,
returns the display of the LCD 5 to the above-described auto calibration top screen CT (FIG. 7),
and then proceeds to the next step SP42 and ends the process. .
[0197]
As described above, the control unit 10 of the home server 2 sets the 7.1ch speaker system
corresponding to the speaker pattern icon AC20 arbitrarily selected from the speaker pattern
selection display screen SPSD (FIG. 53), and the specifics thereof. The speaker arrangement state
can be displayed as a visual image, so that the speaker system can be set while causing the user
to realistically visualize the speaker arrangement state only by the icon selection operation.
[0198]
(5) Operation and Effect In the above configuration, the home server 2 of the AV system 1
displays the measurement result screen MFN (listing the relationship between the arrangement
state for the plurality of speakers 4 and the speaker setting content for the plurality of speakers
4 19) and the like on the LCD 5, the speaker arrangement state of the multi-speaker system and
10-05-2019
42
each speaker 4 at one time, as compared to the conventional case where the speaker setting is
performed only by the FL tube 14 having poor display capability until now. While being able to
make a user visually confirm the speaker setting content, it is possible to intuitively recognize the
speaker system.
[0199]
In particular, in order to perform setting for a plurality of speakers 4 in the related art, it has
been necessary to set the plurality of speakers 4 because one speaker 4 has to be set individually
individually using only the FL tube 14 of the home server 2. Although the user must store setting
values, the user is forced to use a complicated and complicated setting method for the user, but
in this AV system 1, the arrangement state for the plurality of speakers 4 and the speaker setting
contents for each speaker 4 are At the same time, the speaker setting operation can be
performed while visually confirming it, so that the operability can be further improved.
[0200]
Further, in the AV system 1, since the user only has to operate the sound field setting for the
sound field space as instructed along the flow of various GUI screens, it is possible to easily
execute the sound field setting operation, and By displaying the operation explanation, error
details, warning notes, etc. on the GUI screen, the system status and subsequent measures can be
presented easily without having the user read the instruction manual. It can be understood.
[0201]
Furthermore, in the AV system 1, the arrangement state of the plurality of speakers 4 is as if the
user's viewpoint was switched from the three-dimensional speaker selection screen SS1 (FIG. 35)
to the two-dimensional speaker level screen SLV1 (FIG. 40). Since the GUI screen can be
displayed and controlled from the viewpoint of the user's comprehension, such as displaying, it is
possible to provide a graphical user interface that can instantly understand the contents of the
GUI screen at a glance for the user. it can.
[0202]
In addition, in the AV system 1, for contents which would be more easily understood by the user
if expressed in three dimensions, the speaker size screen SSZ1 (FIG. 42), the speaker size screen
SSZ2 (FIG. 43), the speaker height Three-dimensional display is performed from the beginning,
such as the selection screen SHS1 (FIG. 45) and the speaker height selection screen SHS2 (FIG.
46).
10-05-2019
43
[0203]
Furthermore, in the AV system 1, for example, in response to the left front speaker 4FL being
selected and determined on the speaker selection screen SS1 (FIG. 35), a speaker level screen
SLV1 (FIG. 40) for manually setting the left front speaker 4FL is displayed. When displayed, only
the left front speaker 4FL, which is a target for manual setting, is displayed by a solid line or a
hatching process, and the other speakers 4 are thinly displayed by a broken line or the like so
that manual setting operation or selection and determination can not be performed. By this, it is
possible to prevent the erroneous operation at the time of the manual setting of the user in
advance and surely.
[0204]
Furthermore, in the AV system 1, when setting the sound field characteristics of the sound field
space using a plurality of types of speakers 4, a speaker pattern consisting of a very large
number of matrix combinations exists depending on the presence, size, etc. of each speaker 4.
However, instead of presenting it as a matrix table to the user, the speaker pattern can be
selected by causing the user to visually confirm actual visual images for a plurality of speaker
patterns via the speaker pattern selection screen SPSD (FIG. 53). It is possible to easily execute
the manual sound field setting process to be set by the.
[0205]
According to the above configuration, the AV system 1 can provide a graphical user interface
which can more easily execute the sound field setting operation in comparison with the related
art.
[0206]
(6) Other Embodiments Although the flow of a single GUI screen has been described in the above
embodiment, the present invention is not limited to this, and various other combinations and
sequences may be used as the screen transition of the GUI screen. It may be changed to
[0207]
Further, in the above embodiment, the case where only one speaker 4 for which manual setting is
to be performed is selected by the speaker selection screen SS1 (FIG. 35) to the speaker selection
screen SS5 (FIG. 35) has been described. The invention is not limited to this, and a plurality of
speakers 4 to be manually set may be selected.
[0208]
10-05-2019
44
Furthermore, in the above-described embodiment, the control unit 10 of the home server 2
develops the sound setting program stored in the ROM on the RAM, and according to the sound
setting program, an automatic sound field setting processing procedure using a GUI (FIG. 32) The
manual sound field setting process procedure using GUI (FIG. 50) and the manual sound field
setting process procedure using speaker pattern using GUI (FIG. 51) have been described. The
present invention is not limited to this, and the various processing procedures described above
according to the sound setting program installed from the recording medium such as CD
(Compact Disc), DVD (Digital Versatile Disc) or semiconductor memory by the control unit 10 or
the sound setting program downloaded from the Internet May be performed.
