Sound model for railway model
[0001]
BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a
sound model of a railway model that generates sound effects of a railway model.
[0002]
Conventionally, as a sound model of a railway model, there is, for example, one as disclosed in
Patent Document 1.
In this sound effect generating device, the running sound of the vehicle, the sound effects
relating to the brake, etc. are stored in the ROM as voice data. The sound reproduction LSI reads
out the sound data of the ROM at a speed according to the operation state of the master
controller that controls the traveling state of the railway car model, converts it into an analog

signal by the D / A converter, and supplies it to the speaker. In addition, although not disclosed
by patent document 1, what recorded the driving ¦ running ¦ working sound etc. of the actual rail
vehicle is used as audio ¦ speech data.
[0003]
JP 2003-93754 A
[0004]
According to the technology of Patent Document 1, since it is based on the actual traveling sound
and the like, it is possible to obtain a sound effect with reality, but the actual traveling state of the
railway car model and the physical characteristics of the railway car model Because it generates
sound effects independently, it is lacking in interest.
In particular, since only the control of sound effects according to the speed of the railway model
is performed, for example, the railway vehicle travels when approaching, passing, and leaving
near a position on a specific rail of the railway model Even when trying to reproduce changes in
sound, such sound effects can not be reproduced, and in addition, it is possible to reproduce the
sounds that are generated each time a plurality of railroad car models pass the gap position of
the rail, for example. Can not. Further, the technology of Patent Document 1 requires a ROM for
storing voice data, a voice LSI, a CPU for controlling these, etc., which increases the cost, and can
be mounted on a product used by a train model beginner It was difficult.
[0005]
An object of the present invention is to provide a railway model sound effect generator capable
of faithfully reproducing a change in traveling sound at low cost.
[0006]
The sound model of a railway model according to one aspect of the present invention includes a
rail unit.
In the rail unit, at least two rail members on which the railcar model travels are disposed on the
04-05-2019
2
base with a gap therebetween. In addition, the rail is fixed to the base via a tie provided by
removing the vicinity of the gap of the rail. The tie may be integral with the base or may be
separate from the base. Vibration sound detection means is disposed near the gap to detect
vibration sound generated when the railway car model travels. For example, a piezoelectric
element can be used as the vibration sound generation means.
[0007]
The sound effect generator of a railway model according to another aspect of the present
invention also has a rail unit. In this rail unit, at least one rail member out of the plurality of rail
members obtained by dividing the rail on which the railcar model travels along the length
direction is disposed on the base. The at least one rail member has a gap between another rail
member adjacent on one end side of the at least one rail member, and is fixed to the base via a tie
provided apart from the gap. Vibration sound detection means is disposed near the gap to detect
vibration sound generated when the railway car model travels. For example, a piezoelectric
element can be used as the vibration sound generation means.
[0008]
In the sound effects generator of the railway model of both of these aspects, the vibration noise
detection means is a vibration noise generated when the railway car model approaches the
vibration noise detection means, passes near the vibration noise detection means, and leaves.
Since the detection is performed, it is possible to detect a sound that changes in the same manner
as a sound generated when an actual railway vehicle passes. In particular, since a gap is formed
between adjacent rail members and the vibration noise detection means is disposed in the
vicinity, the actual railway vehicle generates the sound generated when the rail car model passes
through the gap between the rail members. It is very similar to the sound produced as it passes
through the gaps present in the actual rail. In addition, since the sleepers supporting the rail
members are excluded near the gap, the rail members vibrate when passing through the railway
car model, and it is possible to realistically reproduce the sound generated when passing through
the gap. Furthermore, since a ROM for storing voice data, a voice LSI, and the like are not used,
costs can be reduced.
[0009]

Vibration adjustment means may be provided for adjusting the vibration state of the rail when
the railway car model travels in the vicinity of the gap. As this adjustment means, for example, a
tie in the vicinity of the gap can be detachably configured, or the tie in the vicinity of the gap can
be made movable along the longitudinal direction of the rail member. The rail near the gap is in a
cantilevered state, since there are no sleepers near it. Then, by removing the sleepers close to the
gap or moving the sleepers, the cantilever state changes, so that the sound effect according to the
preference of the user of the sound effect generator of this railway model is generated. can do.
[0010]
Filter means for filtering so as to emphasize a specific frequency range of the output signal of the
vibration sound detection means, and amplification means for amplifying the output signal of the
filter means and supplying the amplified signal to a speaker arranged near the gap of the rail And
can also be provided. The filter means may, for example, emphasize the low frequency range of
the detected vibration sound. Since the vibration sound in which the specific frequency region is
emphasized in this manner is amplified by the amplification means and output from the speaker,
more realistic traveling sound can be reproduced. In addition, since the speaker is disposed near
the installation place of the vibration sound detection means, the vicinity of the place where the
railway car model approaches and separates from the traveling noise as the railway car model
approaches and changes away. You can listen to
[0011]
As described above, according to the present invention, it is possible to reproduce, at low cost,
sound effects that change in accordance with the traveling state of a railway car model.
[0012]
The sound effect generator for a railway model according to the embodiment of the present
invention is embodied in a railway model as shown in FIG.
For example, a plurality of, for example, 16 rail units are combined on one surface of a
rectangular base 2, for example, to form a rail 4 on which a railway model (not shown) travels.
The rail units include a linear rail unit 4a, a curved rail unit 4b, a sensor rail unit 4c, and an iron
bridge sensor rail unit 4d. A railcar model (not shown) on the rail 4 travels by the operation of
the master controller 3.
04-05-2019
4
[0013]
As shown in FIGS. 2 and 3, the linear rail unit 4a is on the linear base 6a, and the curved rail unit
4b is on the circular arc base 6b. 8a, 8b, 8b. The rail members 8a, 8a are arranged at
predetermined intervals in the width direction of the base 6a and along the length direction of
the base 6a. Similarly, the rail members 8b and 8b are arranged on the arc-shaped base 6b so as
to be curved along the base 6b at the same intervals as the rail members 8a and 8a in the width
direction of the base 6b. Between the bases 6a and 6b and the rail members 8a and 8b, there are
interposed sleepers 10 arranged in a line at regular intervals along the length direction of the
bases 6a and 6b. These sleepers 10, 10... Are integrally formed with the bases 6a, 6b. The rail
members 8a, 8a, 8b are provided on the upper surfaces of the ties 10, 10, ... by the sandwiching
portions 11, 11 ... provided so as to be located on both sides of each of the rail members 8a, 8a,
8b, 8b. , 8b are fixed to the sleepers 10, 10.
[0014]
In the sensor rail unit 4c, a plurality of pairs of, for example, two pairs of rail members 80a, 80a,
80b, 80b are disposed on a base 6c similar to the base 6a. The distance between the rail
members 80a and 80a and the distance between the rail members 80b and 80b are the same as
the distance between the rail members 8a and 8a and the distance between the rail members 8b
and 8b. The rail members 80a, 80a, 80b, 80b are disposed along the length direction of the base
6c, and a gap is formed between the rail members 80a and 80b. In addition, no gap is formed at
the joint between the rail members 80a and 80a of the sensor rail unit 4c and the rail members
8a and 8a of the linear rail unit 4a. Similarly, no gap is formed between the joint portions of the
rail members 80a and 80a of the sensor rail unit 4c and the rail members 8b and 8b of the arcshaped rail unit 4b.
[0015]
In the vicinity of the gap between the rail members 80a, 80a, 80b and 80b, vibration sound
detection means, for example, a piezoelectric element, specifically, the piezoelectric element 16 is
disposed. For example, in the sensor rail unit 4c, a recess 18 opened to the lower side of the base
6c in order to reduce the thickness of the portion corresponding to the gap between the rail
members 80a, 80a and 80b, 80b in the base 6c. Is formed. A piezo element 16 is attached to the
04-05-2019
5
bottom of the recess 18. The piezo element 16 generates a signal, for example, a voltage
according to the vibration generated at the bottom of the recess 18 when the railway car model
travels on the rail members 8a, 8b, 80a, 80b. By disposing the piezoelectric element 16 in the
recess 18, the vibration noise actually generated by the railway vehicle model can be collected
well, and the influence of the vibration transmitted through the base 2 is eliminated. it can.
[0016]
Sleepers 100, 100,... Are arranged at regular intervals also between the rail members 80a, 80a,
80b, 80b and the base 6c. Like the sleepers 10, these sleepers 100 are also integrally formed
with the base 6c. However, a plurality of sleepers 102, 102 located on both sides of the gap
between the rail members 80a, 80a and 80b, 80b are formed separately from the base 6c, and
on both sides of the sleepers 100, 102 on the base 6c. It is being fixed by the fixing means, for
example, the nail ¦ claw 140, to the fixing ¦ fixed part 120 provided so that each may be located.
The rail members 80 a and 80 b are fixed to the sleepers 100 and 102 by the sandwiching
portion 11 provided on the sleepers 100 and 102 in the same manner as the rail members 8 a
and 8 b are fixed to the sleeper 10.
[0017]
By removing the nail 140, it is possible to remove a plurality of ties 102 respectively located on
either side of the gap, as indicated by the dashed line. That is, the sleepers 102 are provided
detachably with respect to the base 6c. Thus, by removing the ties 102 located on both sides of
the gap from those close to the gap, the portions not secured by the ties 102 located on both
sides of the gap of the rail members 80a, 80a, 80b, 80b are The railway vehicle model vibrates
freely when traveling on this, and the low frequency range of the vibration noise detected by the
piezo element 16 is emphasized, so that the actual railway vehicle is an actual railway vehicle. It
makes a sound close to the running condition.
[0018]
In addition, the frequency characteristics of the vibration noise detected by the piezoelectric
element 16 change depending on the number of the removed ties 102. Therefore, since the
sleepers 102 are configured to be detachable, the number of the sleepers 102 to be removed can
be arbitrarily changed so that the user's favorite vibration sound of the sound effect generator is
04-05-2019
6
detected. A vibration adjusting means is configured by making the sleepers 102 detachable.
[0019]
Alternatively, a plurality of removable sleepers 102 may be removed, and instead, a plurality of
sleepers may be provided along the length direction of the rail members 80a and 80b in the
section provided with the sleepers 102 on both sides of the gap. It is also possible to adjust the
distance between the cross ties which can change these positions, and change the vibration state
of the rail members 80a, 80a, 80b, 80b so as to detect the vibration sound of the user's
preference. The vibration adjusting means can also be configured by movably forming the tie.
[0020]
The vibration sound collected by the piezoelectric element 16 is supplied to the sound emission
system 20 disposed in the vicinity of the sensor rail unit 4c as shown in FIG. In the sound
emission system 20, as shown in FIG. 4, the vibration sound collected by the piezo element 16 is
waveform-shaped by the shaping unit 22 and then the filter unit, for example, the bass
adjustment unit 24 functioning as an equalizer and treble adjustment After the frequency
characteristics are adjusted by the unit 26 so that, for example, the bass is emphasized, the
power is amplified by the amplification means, for example, the power amplifier 28 and emitted
from the speaker 30.
[0021]
When the railway car model is traveling on the rail 4, the vibration noise due to this traveling is
detected by the piezo element 16. When the railway car model is traveling at a position away
from the piezo element 16, the vibration noise detected by the piezo element 16 is small, and
when the train model approaches the piezo element 16, the vibration noise detected Will also
grow. Then, when the railway car model passes above the piezo element 16, the vibration noise
detected is also maximum. Moreover, when a plurality of railcar models are connected, it
resembles the sound generated when the actual railcar passes through the gap of the actual rail
whenever the wheel of each railcar model passes through the gap. Vibration sound is generated,
and this vibration sound is detected by the piezo element 16. Therefore, the vibration noise
generated according to the number of railway vehicle models, the position of the wheels, and the
number is detected. In addition, when a railway model vehicle in the middle of a plurality of
04-05-2019
7
railway model vehicles passes through the gap portion, the vibration noise generated by the
leading railway vehicle model which has already passed through the gap and is separated is also
a piezo element 16 is detected. Therefore, it is possible to detect the vibration sound which
approximates to listening to the sound effect according to the traveling state of the railway car
model near the gap of the rail members 80a and 80b. Further, as described above, by removing
the cross ties 102 on both sides of the gap between the rail members 80a, 80a and 80b, 80b, the
portions on both sides of the gaps of the rail members 80a, 80a, 80b and 80b are freely vibrated.
Because of this, it is possible to detect the vibration noise which is further approximated to the
noise generated when the actual railway vehicle travels on the rail gap.
[0022]
The detected vibration sound has a frequency characteristic such that the bass is enhanced by
the bass adjustment unit 24 and the high-tone adjustment unit 26 of the sound emission system
20 disposed in the vicinity of the gap between the rail members 80a, 80a and 80b, 80b. Since the
sound is adjusted and emitted from the speaker 30, a sound closer to the sound generated when
an actual railway vehicle approaches, passes, and goes away from the rail gap is used for this
sound effect generator. A person can listen in the vicinity of the gap between the rail members
80a, 80a and 80b, 80b. Moreover, this traveling noise occurs when the actual railway vehicle
passes through the gap of the rail each time the wheels of each railway vehicle model pass over
the gap, when there are a plurality of railway vehicle models in operation. A sound similar to the
sound is generated, and a traveling sound corresponding to the number of railroad car models is
generated.
[0023]
As shown in FIG. 5, the iron bridge sensor rail unit 4d is configured substantially the same as the
sensor rail unit 4c. That is, the iron bridge sensor rail unit 4d has a base 6d, and the rail
members 82a, 82a, 82b and 82b form a gap between them, like the rail members 80a, 80a, 80b
and 80b of the rail sensor 4c. Are disposed on the base 6d via sleepers 110, 110... Integrally
formed with the base 6d. The rail members 82 a, 82 a, 82 b and 82 b are fixed to the sleeper 110
by the sandwiching portion 11. A plurality of sleepers 112 are provided on both sides of the gap
between the rail members 82a, 82a and 82b, 82b. The sleepers 112 are formed separately from
the base 6 d in the same manner as the sleepers 102 and are provided detachably with respect to
the base 6 d, and a predetermined number of those close to the gap is removed. In the same
manner as described above, in place of the removable tie 112, a plurality of sleepers movable
along the longitudinal direction of the rail members 82a and 82b may be provided on both sides
04-05-2019
8
of the gap.
[0024]
A recess 180 is formed below the gap, and at the bottom of the recess 180, for example, a piezo
element 160 is disposed as sound detection means. Truss structure parts 32 are provided on
both sides of the rail members 82a and 82b. The truss structure portion 32 is made of, for
example, a synthetic resin. Both ends of the base 6 d are fixed to the base 2 by bridge legs 34,
34. Although not shown in FIG. 5, they are joined to the adjacent rail units on the bridge legs 34,
34 erected on the base 2.
[0025]
As shown in FIG. 1, the vibration noise detected by the piezoelectric element 160 of the iron
bridge sensor rail unit 4d is supplied to the sound emission system 20a disposed in the vicinity
of the iron bridge sensor rail unit 4d. As shown in FIG. 6, the sound output system 20a includes a
shaping unit 22a, a bass adjustment unit 24a, a high-tone adjustment unit 26, a power amplifier
28a, and a speaker 30a, and these configurations are the shaping unit 22 of the sound emission
system 20. , Bass adjustment unit 24, treble adjustment unit 26, power amplifier 28, and speaker
30. Therefore, when the railway car model passes on the sensor rail unit 4c, the running sound
similar to the sound emitting system 20 can be emitted from the speaker 30a.
[0026]
However, since the running noise generated when the railway vehicle actually passes the iron
bridge passes over the metal truss structure, various running noises generated when the railway
vehicle passes on the rail are various. The frequency component of H is included to give a
complex sound effect. However, even if the railway car model passes on the synthetic resin truss
structure portion 32, such a complicated acoustic effect is not provided. Therefore, white noise
generating means for generating white noise, for example, white noise generated by the white
noise generated by the white noise generating unit 36, may be synthesized by, for example, the
synthesizing unit. It is synthesized by 38. White noise has various frequency components, but its
level is constant, so merely synthesizing white noise gives an acoustic effect to be applied when
the railway vehicle passes through the truss structure 32. It is not possible. Therefore, the
vibration sound from the shaping unit 22a is supplied to an envelope detection unit, for example,
04-05-2019
9
the envelope detection unit 40 to detect the envelope of the vibration sound, and the detected
envelope and white noise are added to the envelope addition unit, for example, an envelope
addition unit. By supplying the white noise to the white noise, the white noise to which the
envelope of the vibration noise is added is supplied to the synthesis unit 38.
[0027]
Therefore, when the railway vehicle model is traveling at a location away from the iron bridge
sensor rail unit 4d, the envelope providing unit 42 supplies the synthesis unit 38 with the
envelope value because the value of the vibration noise detected by the envelope detection unit
40 is small. The level of white noise is also small. As the railway car model approaches the iron
bridge sensor rail unit 4d, the envelope value of the vibration noise detected by the envelope
detection unit 40 also increases, and when passing over the steel bridge sensor rail unit 4d, the
value of the vibration noise envelope The value of the envelope of the vibration noise also
decreases as the railway car model moves away from the iron bridge sensor rail unit 4d. The
level of the white noise from the envelope applying unit 42 also changes according to the change
of the envelope of the vibration sound. In addition, when the wheel of the railway car model
passes through the gap between the rail members 82a and 82b, the envelope of the vibration
noise changes, but following this change, the envelope of the white noise also changes.
[0028]
As described above, since the white noise whose level changes in accordance with the traveling
of the railway car model is added to the traveling noise generated according to the traveling of
the railway car model, when the railway car is traveling on the iron bridge The traveling sound
similar to the traveling sound generated in the vehicle can be emitted from the speaker 30a of
the sound emission system 20a.
[0029]
The gap between the rail members 80a and 80b and the gap between the rail members 82a and
82b are large enough to allow free vibration when the railway vehicle passes and to the extent
that the wheels of the railway vehicle model do not derail Is set to the size of.
In the case of the N gauge, the track width is 9 mm, and the scale of the entire railway model is
1/148 to 1/160. In this case, the gap is set to 1 to 2 mm.
04-05-2019

[0030]
The railway car model flows from the master controller 3 and travels on the rail 4 using the
current returned to the master controller 3 as a driving source. Therefore, in the same layout of
the rails 4, the gap is set like the sensor unit 4 c or the iron bridge sensor unit 4 d. When there is
only one equipped rail unit, current can be supplied to the rail members located on both sides of
the gap through the wheels of the railway model passing above the gap, but the rail unit with the
gap In the case where there are a plurality of rail cars, even if the rail car model passes through
one rail unit having a gap, the passage of current is blocked by the other rail units having a gap,
and the rail car model can not travel. Therefore, in each rail unit having a gap, a bypass circuit is
provided to bypass the gap and allow current to flow.
[0031]
In the sensor rail unit 4c and the iron bridge sensor unit 4d of the above embodiments, gaps are
formed between the rail members 80a and 80b provided on one of the bases 6c and 6d and
between the rail members 82a and 82b, respectively. As shown in 7, a gap may be formed
between a pair of rail members 84a, 84a, 84b, 84b on the bases 6e, 6f of two rail units 4e, 4f
arranged adjacent to each other. Normally, the rail members 84a, 84a, 84b, 84b are formed to
have a length equal to the length of the bases 6c, 6d, but when using, for example, the rail unit
4e side as a sensor unit, the rail members of the rail unit 4e The length dimension of 84a, 84a is
made shorter than the length dimension of the base 6e, and a gap is formed between the rail
members 84b, 84b at the end of the base 6e joined to the base 6f. The rail members 84a, 84a are
disposed. In the lower part of the base 6e, a recess 182 is formed in the same manner as in the
above embodiment, and the piezo element 162 is disposed therein. When used as a steel bridge
sensor unit, truss structure parts are disposed on both sides of the base 6e, and the output of the
piezoelectric element 162 is supplied to the noise output system 20a. Also, although the rail
members 84a, 84a, 84b, 84b are fixed to the sleepers 112, 114, one or more of the sleepers 112
of the rail unit 6e in the vicinity of the gap are described in the above embodiment. Similarly to
the above, it is configured to be removable or movable along the length direction of the rail
members 84a, 84a.
[0032]
04-05-2019
11
In the above embodiment, the sensor rail unit 4c and the iron bridge sensor rail unit 4d have
linear rail members 80a, 80a, 80b, 80b, 82a, 82a, 82b, 82b, like the linear rail unit 4a. However,
it is also possible to use two pairs of rail members curved similarly to the curved rail unit 4b.
However, they are arranged to form a gap between the two pairs of rail members, and the piezo
elements 16 and 160 are provided below the gap.
[0033]
In the above embodiment, the piezoelectric elements 16 and 160 that generate a voltage when
pressure is applied are used as the vibration sound detection means, but an element whose
impedance is changed, and this element and a resistor, for example, are connected between DC
power supplies. It is also possible to use one connected in series as vibration noise detection
means. In the above embodiment, the piezoelectric elements 16 and 160 are provided one by one
for each of the sensor rail unit 4c and the iron bridge sensor rail unit 4d, but at different
positions along the length direction of the bases 6c and 6d. Piezoelectric elements may be
respectively provided, and the vibration sounds detected by these may be synthesized and
supplied to the sound emission systems 20, 20a. In this case, if the sizes of the piezoelectric
elements 16 and 160 used are different, the frequency characteristics of the detected vibration
sound are different for each piezoelectric element, so that more realistic traveling sound can be
obtained.
[0034]
In the above embodiment, two pairs of rail members 80a, 80a, 80b, 80b, 82a, 82a, 82b, 82b are
used in the sensor rail unit 4c and the iron bridge sensor rail unit 4d, but three or more pairs of
rails are used. Parts can also be used. In this case, it is desirable to form a gap between adjacent
rail members. In addition, a piezo element can be provided in the same manner as the above
embodiment so as to correspond to these gaps.
[0035]
In the above embodiment, although the bass adjustment unit 24 and the high-tone adjustment
unit 26 are provided in the sound emission system 20, 20a, only one of them may be provided,
or both may be removed.
[0036]
04-05-2019

In the sensor unit 4c of the above embodiment, the nail 140 is used to make the sleepers 102
removable, but the invention is not limited to this, and various configurations are used to make
the sleepers 102 removable. can do.
For example, the respective sleepers 102 may be provided detachably with respect to the fixed
portion 120, and a desired one of them may be removed. The same can be done for iron bridge
rail units.
[0037]
Further, in the above embodiment, a pressure-sensitive element such as a piezo element is used
as the sound detection means in the iron bridge sensor rail unit 4d, but a sound collection means
such as a microphone can also be used.
[0038]
Further, although the sound emission system 20a generates the traveling sound based on the
detection signal of the piezoelectric element 160, the traveling sound is generated without using
the detection signal of the piezoelectric element 160, and the detection signal of the piezoelectric
element 160 is generated accordingly. It is also possible to output as an iron bridge traveling
sound by adding white noise to which the envelope of the above is attached.
