Detailed description of the invention As shown in FIG. 1 in the 4-channel stereo system, speakers
EIL81L8184 are disposed on the left and right of the listener's forearm to reproduce the sound,
but according to the position, volume and frequency of each speaker It is a new type of acoustic
equipment that is enjoying a demolition sound full of a sense of presence by using a key II
associated with the metal phase, and that it is becoming increasingly popular in the nearby city.
The resistance adjustment device for demodulated sound of the present invention is a
conventional slide type variable resistor 49-2440 ': 1-02 anti-1% V1. 'IQ, 73.74, etc. are
simultaneously engaged by a single forceps-4, or by means of an adjustment device which is
intended to make the offending bird the adjustment that seems most appropriate for the listener,
1 will be described in detail with reference to the attached drawings. A four-channel stereo
planar arrangement example by force is a variable resistance for adjusting the volume of each
speaker in relation to its volume, @ 'V1. One piece of VL 73, 74 belongs to each wiring, but the
present proposal relates to the adjusting device which can adjust these four variable resistors
simultaneously with the single-ladder 4, and the planar structure is As shown in FIG. 2, a suitable
panel 2 is provided with a circular or quadrilateral extraction hole 2A, and the lower surface of
the panel is provided with a freely movable plate 3 and a fixed attachment plate 6t in sequence,
and a rectangle below the attachment plate 6 4 variable resistors of shape, that is, V1, V2. V: Fix
S, V4 radially from the center C at equal distances gtK. Therefore, each sliding type resistor 71
Vj2. V3. Each V4Fi is arranged at an angle of 90 ° each, and is connected to a slide groove
3A provided on the freely movable plate 3 of the forelock on the adjustment shaft 5 performing
variable sliding. The sliding grooves 3A are orthogonal to each other when viewed from the
radial direction of the center C, and both are at the same distance from the center C. The ladder 4
is fixed to the central point C of the freely movable plate 3 and the north end of the plate 4 is
mostly taken out from the hole 2A to the panel 2F and within a limited area within the hole 2 and
the hole with all fingers. To be able to move As can be seen in FIGS. 2 and 414, if the forceps
number is pushed upward on the paper as in the example [example 44B-24402-03-example, the
movable plate 3 is wedged like a dotted line. However, because of this, the four tank moving
grooves 3 mm each have resistance 11V1. V1. The shaft 6 slides on the sliding groove 3) because
it moves until it embraces the adjustment shaft S of v3 ° No. 3). Since it slides in the direction of
the long groove in VL 73.74 to change the internal resistance value, one sheet of movement s!
The movement of S moves the four adjustment axes s simultaneously in the longitudinal
direction, and the four variable resistors can change their resistance values together.
Therefore, since the rod 4 can move freely in the extraction hole 2 of the panel 3, the
accompanying moving plate 302 dimensional movement moves the adjusting shaft 5 in a onedimensional direction and the internal sliding resistor Can change the resistance value of
According to the resistance adjustment device of the present invention, it is possible to listen to a
multi-channel signal such as a four-channel stereo sound l1 device by adjusting it to a volume,
sound quality, etc. balanced with one ladder number, so it is at the time of bell noise! The
reproduction sound corresponding to the position of the ic can be reproduced and it is possible
to save the music with a sense of presence, and the resistor itself of the device can use a normal
commercial product, and the mechanism 4 is simple and easy to adjust There is an effect that the
form is also relatively small. Fig. 1 of the ll1 m simple explanation attached drawing shows an
application example of the resistance type adjustment device of the demodulation sound for 4channel stereo blue-collar special effects according to the present invention, and Fig. 2 is 3FL wl
of the present device. 11% The third cabinet is a vertical contractor that can be rotated to the
third to the third in the previous figure, and FIG. 48-24402-044 is a plan view showing an
operation example of the device of the present invention. Utility model No. Debira Japan Enissoid
