DESCRIPTION JPH1156517
[0001]
BACKGROUND OF THE INVENTION At the time of audio reproduction, a low frequency band of
about 20 to 150 Hz of an audio signal is used as a supply source, and the vibration device is
driven by this low frequency band signal to enhance the sense of presence by feeling the
generated vibration. The inventors of the present invention have proposed a number of bodily
sensation sound devices. On the other hand, a flight simulator that uses a large-scale hydraulic
system to swing the cockpit according to the situation is used to give the pilot a sense of reality.
In addition, there is a device that makes a chair attached to a chair with cpu to create a sense of
reality by making a chair or the like swing back and forth, left and right, up and down, and
feeling like riding on a roller coaster or a motorcycle. The present invention relates to a bodily
sensation rocking / oscillating device for creating such realism in music appreciation and game
devices.
[0002]
2. Description of the Related Art In the prior art, there is an electric-mechanical vibration
converter used in a body-sensing device, in which a large mass permanent magnet is suspended
in a mounting container and a coil is fixed in the container (hereinafter referred to as a
transducer). Called). When listening to music while sitting in a chair, a transducer attached to the
chair vibrates the seating surface in the low-pitch range, giving a sense of presence in the playing
hall and the fantasy world triggered by music. Also, in the game machine specification, the user's
body is tilted or shaken according to the situation, but as a device for this purpose, as described
above, the hydraulic device swings the cockpit, the motor, air cylinder, etc. Although it is used as

a moving device, in the air cylinder, piping for injecting and discharging the air is complicated,
and many of them are oscillated and vibrated by a motor because of the simplicity of the device.
[0003]
By the way, in order to make the human body mounted object rattled, the rocking device
achieves the effect by repeating forward and reverse rotation of the motor and injection and
discharge of air into the air cylinder. One shot is one cycle (1 Hz), and a relatively large
fluctuation can be followed at a low frequency. In the case of a motor, forward rotation and
reverse rotation must be repeated according to the frequency, but it is very difficult to perform
rotation angles (amplitudes) at several tens Hz to several hundreds Hz as required. The same
applies to an apparatus using an air cylinder. Therefore, in a device using a motor or an air
cylinder, the response speed to the input of the rocking signal / vibration signal is low, so that
rocking with a sense of speed or a feeling of impact is difficult. In order to cover this
performance, for example, in a motorcycle race (video game), the seat provided on the game
machine is excessively inclined and swung, and the body of the person sitting and operating the
seat is tilted and swung. I am doing it. For example, when a motorcycle is traveling on a rough
and loose road, the body sways slowly, and when traveling slowly on a gravel road, it gives a
feeling of jerky impact. However, when traveling on a gravel road quickly, a large continuous
shock of the output can not be obtained (following the forward or reverse rotation of the motor
because the frequency of the input signal is high), which follows the continuous large shock with
the road surface. The follow-up of the rocking motion does not match, which reduces the game
performance and halves the interest. Therefore, some of the users of the game control the
motorcycle while standing without sitting on the seat.
[0004]
Here, with regard to actual rocking, if a motorcycle and a roller coaster are put together as a
reference, it includes from the thing that is shaken slowly to the left and right, to the vibration
with a sense of shock such as rattling, rattling, and dossin. As a result, it is impossible to
manufacture a satisfactory game machine (game machine) with a rocking device using a motor,
an air cylinder or the like. However, with the above-described vibration device, although it is
possible to feel a physical sensation, it is structurally impossible to swing the body largely to the
left and right.
[0005]

which, as described above, the rocking sensation and the shock are experienced to enhance the
presence.

[0013]
BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be
described below with reference to the attached drawings.
As shown in FIG. 1, a seat (human body mounted object) 1 on which a person playing a
simulation, a game, etc. sits is fixed to the rocking / vibration table (human body mounted object)
2 of the bodily sensation rocking / oscillating device. The table 2 is supported by an arm 4
projecting from the frame 3. When the arm 4 is vertical, the rocking and vibrating table 2 is held
horizontally.
The arm 4 is supported at its middle part by the ball bearing 5, and its upper and lower ends can
swing freely on the front, rear, left, right, and on the plane, and the suction core 6 is attached
below the ball bearing 5. ing.
[0014]
In order to control the swinging motion of the arm 4, electromagnets 7 a and 7 b are installed
opposite to the suction iron core 6 and the magnetic force is interrupted.
Therefore, it is necessary to arrange the arm 4 in at least three directions in order to freely swing
the plane, but in the present embodiment, as shown in FIG. 2, the electromagnets 7 are arranged
in four directions inside the frame 3. It has been installed.
Then, the attraction iron cores 6 are attracted to each other by magnetic action.
10-05-2019
4
As shown in FIG. 3 and FIG. 4, the electromagnet 7 has a configuration in which a coil 72 is
wound around an E-type iron core 71.
The shape of the core is not limited and may be U-shaped.
[0015]
As shown in FIG. 1, output waveforms of opposite phase are input from the output amplifiers A1
and A2 to the electromagnets 7a and 7b arranged symmetrically, and the mixing amplifier 8 at
the previous stage is input the oscillation signal a and the oscillation signal b. , Mixed
amplification.
Thus, when the magnetic force of one of the electromagnets 7a (7b) is maximum, the magnetic
force of the other electromagnet 7b (7a) is minimized, and the attraction core 6 is attracted to
one of the electromagnets 7a (7b).
In addition, when the magnetic force is the same, it is stopped at the center position (when the
input waveform is a constant voltage). Further, the position sensor 9 at the lower end of the arm
4 detects the position (orbit) of the swinging / oscillating arm 4 like a pendulum, and the signal is
fed back to the mixing amplifier 8. This detection signal is used for bias correction (a neutral
position correction of the arm) to correct an angular change of the seat 1 due to a human body
load or the like. That is, the outputs of the left and right electromagnets 7a and 7b are adjusted.
[0016]
The oscillation signal a used here is a waveform consisting of a component of a wavelength
longer than the oscillation signal b, which largely oscillates the sheet 1 or holds the inclined state
for a short time, and the oscillation signal b is The seat at the state position is made to vibrate at
about 20 to 150 Hz (which may be an audio signal in the low frequency range or a body sound
signal as proposed by the applicant). In addition, two sets of mixing amplifiers 8 and peripheral
devices are prepared in order to generate swing and vibration also in the front and rear direction.
However, if there is rocking / vibration in the oblique direction, it is disassembled in the x and y
10-05-2019

directions and interlocked operations are performed.
[0017]
The sensation swing and vibration apparatus described above is installed in conjunction with an
audio device, a video game machine or the like, and is used to enhance the sense of reality. For
example, in a battle action game of a car race, when the vehicle on the screen suddenly
accelerates or decelerates rapidly, the signals from the output amplifiers A1 and A2 to the
electromagnets 7a and 7b are input so that the seat 1 tilts forward and backward. In the contact
battle, the seat 1 is input so as to tilt in the left and right direction. These can be performed by
changing the swing signal a. In addition, it is possible to control the shock from the ground when
the car enters a mountain road from a highway (paved road) on the screen by the vibration signal
b. In order to experience a sharp curve on a mountain road on the screen 1 on the screen, it is
necessary to tilt the sheet 1 in the left and right direction, which is performed by combining
changes in the rocking signal a and the vibration signal b. be able to.
[0018]
Also, by incorporating such a story into car racing game software, as shown in FIG. 1, by moving
the operation lever 11 while looking at the traveling road (traveling condition) of the car to be
operated on the display 10 of the game machine, It makes you feel like you're riding a car in the
game.
[0019]
Further, as described above, it is a matter of course that the sense of reality can be further
enhanced by using the sensation swing and vibration device at the time of audio reproduction.
[0020]
Next, a modified example of the bodily sensation rocking / oscillating device will be described
with reference to FIG.
The human body placement portion 2 in the seat 1 can be inclined in all directions by the
movable joint 12, and suction iron cores 6 are attached to the lower part of the human body
placement portion 2 in the xy direction.
10-05-2019

Further, an electromagnet 7 is installed on the base 13 to which the movable joint 12 is fixed so
as to face the suction core 6. (Position sensor is not shown). According to this configuration,
since the arm 4 does not need to be elongated, the frame can be flattened.
[0021]
Further, as shown in FIG. 6, by attaching the permanent magnet 14 to the suction core 6
disposed at the lower part of the human body mounting portion 2, the repulsion force can be
obtained if the electromagnet 7 and the permanent magnet 14 have the same polarity in the
steady state. Works, and the human body mount 2 can be stably kept horizontal. In addition,
since the magnetic force of the permanent magnet 14 is added to the magnetic force of the
electromagnet 7 at the time of operation, the responsiveness is improved. In addition, it is also
possible to attach the permanent magnet 14 to the attraction | suction iron core 6 shown in FIG.
1, and to utilize attraction | suction force and repulsive force. In addition, although illustration is
omitted, when it is going to give rocking and vibration in the vertical direction to the sheet 1, the
rocking and vibrating table 2 is held in a lifted state, and the suction iron core 6 starting from
this position is The electromagnets 7 are arranged at the upper and lower positions.
[0022]
As shown in FIG. 7, in the sensational swing and vibration apparatus, the frame 3 is formed into a
rectangular shape, and the electromagnet 7 (external shape, a block having a side of about 20 cm
on one side) is attached in four directions. A movable shaft 41 held at 51 and a swing / vibration
table 2 fixed to the upper end of the movable shaft 41 are provided. A movable iron core 61 is
mounted on the movable shaft 41. The movable core 61 is adapted to move in a pendulum shape
about the ball bearing 51. The seat 1a of the motorcycle specification is attached to the rocking /
vibration table 2, the maximum load is set to about 125 kg, and the bank angle is made to
correspond to the movable axis being inclined 0 to 13 degrees with respect to the vertical. The
action force of the movable core 61 is output about 0 to 28 kg. The seat 1a of the motorcycle
specification is made of plastic except for the main part to reduce the weight and reduce the load.

Further, a position sensor 9 is provided at the lower end of the movable shaft 41, and a tension
spring 15 is connected to the frame 3 so as to always keep tension and maintain the middle point
of the movable shaft 41. Therefore, when the electromagnet 7 is operated by the rocking signal a
and the rocking signal b, the rocking / vibration table 2 is rocked and vibrated, and the seat 1a of
the motorcycle specification is also rocked and vibrated simultaneously. The player riding on 1a
experiences swings and vibrations and can be combined with the display of the game machine to
obtain a sense of reality. Further, although the example in which the seat 1a of the motorcycle
specification is attached to the rocking and vibrating table 2 is taken as an example, the invention
can also be applied to a vehicle other than a motorcycle. Further, the seat 1 shown in FIG. 1 may
be fixed to the rocking / vibration table 2, and the surroundings may be surrounded by a cockpit
style to provide an atmosphere.
[0024]
The present invention is configured as described above, and according to the invention of claim
1, the response of the swing signal and the vibration signal of the electromagnet is true, so that
the desired swing of the human body mounting object is achieved. The vibration can be
generated, and the arrangement of the electromagnets can generate two-dimensional and threedimensional rocking and vibration, and can normally reproduce the rocking and vibration felt by
the human body. Further, according to the inventions of claims 2 and 3, by disposing the
electromagnets in the xy direction or the z direction, the oscillation / vibration in multiple
directions is decomposed into elements of xyz to facilitate control. Can. Further, according to the
invention of claim 4, the arm length can be shortened by directly attaching the suction iron core
in the xy direction to the lower part of the human body mounting object, so that the apparatus
can be flattened, and the game machine etc. The height of the sheet can be reduced, which makes
the design of the device advantageous. Furthermore, according to the fifth and sixth aspects of
the present invention, the human body mounting material used when playing audio, watching a
movie, playing a video game, etc., pours out a bass range signal from among these video and
audio signals, By oscillating the oscillation signal and the vibration signal and operating the
electromagnet, the oscillation and the vibration can be synchronized with the audio-visual to
obtain a more realistic sensation.
