DESCRIPTION JPS55129000
# 4 Letter 1, title of invention
ステレオアジャスタ
3. Detailed description of the invention The present invention is to adjust the volume balance of
the stereo device Listening to the stereo balance sound with the ear and turning the sound i
adjustment knob so that the sound can be heard from the center of the stereo device, Because it
is done by the human sense k of acupuncture and moxibustion company, it is also difficult to
expect the diffraction by an obstacle such as furniture to be accurate. Also, even with stereo
devices that are preset so that the inputs from the amplifier to the left and right speakers are
equal, the adjustment of the volume balance when looking at a shifted position from the center of
the stereo. '&'. The listener poi, the output from multiple Sbika such as this li 杜, stereo etc? In
this case, it is a stereo ananocaster capable of properly adjusting stereo parameters by
appropriately or visually feeding mechanical and electrical κ feed packs of each of the input
signals in a state almost similar to the listener listening. The embodiment of the present invention
will be described above. In the first embodiment of the present invention shown in FIG. 1k, the
balance adjuster (1) 杜, left and right rusted surface 面 microphone Il1) and + i> surface κ v 面
meter (3) and (i) A sound collecting plate (4) and (i) simulating the shape K of the rear face 社
company ear of the microphone 121 and (i) is disposed. The left and right of the stereo adjuster,
the left and right of the stereo adjuster "2" and (2) catch the sound coming out of the stereo, and
the sound that enters each microphone is displayed by the VU meters (3) and (8 '), Turn the
volume balance adjustment knob (8) of the stereo amplifier (7) while watching the meter so that
the listener a force is equal to both, the volume balun of the stereo device (5) Ru. In the stereo
adjuster of the second embodiment of the present invention shown in FIG. 2, the microphones (2)
and (2) are not provided on the side of the adjuster, but the side K of the two front meters (3) and

(3) is provided It is. In addition, the third embodiment of the present invention as shown in FIG.
K, stereo adjuster company of the third embodiment of the present invention, a pointer type
analog meter (3) and (3) on the adjuster shown in FIG. (9) and (d) are used to arrange the ear
plate +4+, tj + and the laterally oriented microphone 121, ti +. The stereo adjuster (1 ') of the
fourth embodiment of the present invention shown in FIG. 4 is provided with the meter (3) and +
a + in the adjuster of FIG. 1 on the opposite side to the direction in which the microphone faces.
The volume balance knob (A) is provided on this side, and when using it, connect the annoaster
with the amplifier (7) of the stereo device (5) with I as shown in the figure, and adjust the volume
balance-adjustment on the amplifier side. The listener a is operated by remote control while
looking at the meters (3) and (i) not by the VR knob (8) but by the VR knob Q6 on the annoaster
side.
FIG. 5 is a front view of the adjuster of FIG. 4; However, it may be a servo type in which (8)
rotates in proportion to the rotation of (d), or an auto feedback type in which the difference
between the outputs of microphones +21 and +21 is automatically detected to move (8). As it can
be constructed by ordinary technical knowledge of concrete circuit lines such as Gangno et al., It
will not be described here. FIG. 7 shows the fifth embodiment of the present invention, in which
the stereo amplifier (7) is provided with the meter fa 131 and the balance adjustment VR knob
GO described in FIG. 1 to FIG. VU meter in amplifier 1. i and i will be provided in addition to
Paransa I Apart from the same surface shape as the human face, the microphone in the direction
of the QIK side is +21. The output of the one in which ti + is embedded is connected by an
amplifier (7) K connection. 8 requires four meters of ms, ai + a + and ta + in FIG. 7, while only two
meters are provided and a changeover switch (d) is provided to make the meter (3) <Even in this
case, since the right and left volume balance of the stereo device is accurately adjusted, it is
possible to accurately and easily make the adjustment for reproducing the excellent nine stereo
effect. The structure and wiring of the stereo adjuster of the present invention are not limited to
the above embodiment, and various other aspects may exist, all of which are included in the
present invention. Also, in the case of being completely separate from the amplifier, in the case of
being separate but combined with the amplifier, or being integrated with the amplifier, etc. It is
included in The meter indication type manual adjustment servo type, an anobalance automatic
feedback type, etc. are all included in the present invention.
