DESCRIPTION JPS4880502
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of a sound field display
device of the present invention, FIG. 2 is a characteristic diagram of a display lamp used for a
display portion of the sound field display device of the present invention, and FIG. FIG. 4 is a
schematic circuit diagram of the sound field display device of the invention, and FIG. 4 is an
explanatory view showing a display state of the sound field display device of the present
invention. In the drawings, 1.2.3 indicate first to third display lamps, and 4Ft 4p, 4RR, and 4RLRL
indicate display units. No 4k52 Q /. aQ2 串 ・ ・ ・ ○ -5'O54 (4KK Fig. 1 7 real opening 4880502 (2) \ // ((\ / / \ <b) \ / / ((Figure 4
[Detailed description of the invention] The present invention is a two-channel stereo iL <t, i 4 $
yannel stereo etc) multi-channel stereo low field display device fi (related to K, multi-cha 21 ′ ′
nnerha sound output level The number of if juice output river use! It is a book of 15 to turn off
and announce the t level with a small blue rice lamp with a few warm green lights of Ichikawa
starting to discharge. Conventional multi-channel stereo such as 4 channels; Lou stereo front
lapping rear left lv right friend ,, 48-85002-02 sound field display device to display the sound
output level of the Kinnel, corresponding to the front and rear left and right chicken nether, Each
of the display lamps at the sound output level was provided, and the display lamps were turned
on to display the sound output level of each speaker by the brightness of the display lamp. In the
above case, when the sound output level is above a certain level ', the brightness level of the lamp
is saturated. In order to give a clear indication of the sound output level it was not possible for
1'1 °. The present invention is a book relating to a sound field display device in which the above
drawbacks are eliminated. Hereinafter, the sound field display device of the present invention
will be KWl with the drawing, and the sound field display device m111-t of the present invention,
+5 multi-channel stereo-1 if it is 4 channels 1 ′ ′ Teleo, 70nd and rear respectively A display
unit 4FR14FI1% 4RR14RL, in which a plurality of display lamps 1.18 having different discharge
start 6 pressures are sequentially and linearly arranged corresponding to the left and right

channels, and 2 .. D, each display unit 47 Hs 41 ′ L% 4 R,. , 48-85052-034RL are arranged
radially as shown in FIG. The display section 47R% 4FL% 4R, 4RLFi As shown in FIG. 2, the first
display lamp with a discharge start voltage of QmW], the second display lamp 2 with a discharge
start voltage of 1QQmW, group 1ff start lightning is 1W No. 11 of the discharge start voltage of
the 8th indicator lamp 8 of! The display lamp 1 is disposed in order from the inside to the
discharge start voltage, and the season 8 display lamp 8 is sequentially disposed to the outside.
As shown in FIG. 8, the above-mentioned sound field display-made V 1 '□ acoustic output of
each of the above channels is displayed on each display unit 4F, 4' IPL 14 RR 14 RL input
terminal 5 F 8.5 F or 5 R □, 5 R And the respective input terminals 5FR, 5 ′ ′? From 01.5 RR,
5 RL, respectively-via 1st to 3rd Township Resistor fl, 7.8, 1-1st child of 8th display lamp 1% of
the above display part 4FR, 4FL% 4RR 14R5L The circuit is connected to 2.8 respectively.
The first to the first indicator lamps 1.48-8502-04 (see FIG. 2) in which the two first to eighth
variable resistors 6.7.8 are arranged in fours to perform the discharge start characteristic as
shown in FIG. It's a book that gets 313.8. In order to clarify each other's display between the
respective display parts of the supraorth sound field display apparatus, a gap between the
respective display parts may be provided. Next is the sound field display as described above! If
the sound output levels of the front and rear left and right channels are small, the first display
power of the display portions 41FR, 4, PL, and 4RR 14RL of the respective channels is described.
Only, and a small range of Table 10 is made as shown in FIG. 1). Also, when the sound output
levels of the front and rear left and right husbands of 10 channels are somewhat large, the
display portions 41PR% 4 of the above-mentioned respective channels? The first display run
force l and the eleventh display lamp 2 of □, 4RR and 4RL are turned on, and a display of a
slightly larger range of 1CK is made as shown in FIG. 4 (chi). When the sound output levels of the
left and right channels of the 21 heront and the rear are large, the display portions 47R% 4FL,
4RR, 4RL (all of the first to srs display lamps 1.2.8 of the above channels are displayed. Is it a
point? l Fig. 4 &! A large range of displays is made as shown by IK. .
48−80502−05(4)る。 Also, if the sound output levels of the respective speakers
are different, the first to third display lamps 1, g, 3 of the respective display portions
4FR14FL14RR14RI1 are turned on according to the respective sound output levels, and display
is performed. Ru. Although the display of the sound output level of each speaker has been
described in the above description, it goes without saying that the display of the sound output
frequency level can be similarly performed. Since the present invention is configured as
described above, it is possible to clearly display the sound output level and the sound output
frequency level state of each speaker.
