[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
vibrator, which converts this sound into an electrical sound signal and generates a vibration
according to the sound signal with respect to the sound heard by a speaker, earphone etc. The
present invention relates to an easy-to-wear type bodily sensation vibrating device which can
experience information vibration and can be used as a virtual experience.
[0002]
2. Description of the Related Art In the past, in order to experience music and the like in the body
in addition to hearing from the ear, an electric-mechanical vibration transducer that vibrates with
the audio signal of music has been manufactured. By operating with an audio signal, comfortable
vibration can be experienced. For example, an electric / mechanical vibration converter is
attached to a chair in the listening room, and the vibration of the chair due to the music signal is
felt together with the music from the ear, to create a sense of reality. In particular, it is more
effective to express the bass part such as an imitation sound and an impact sound by vibration.
Also, in aerobics classrooms, when the user's body is moving with dance music, it is not enough
to grasp the music from the ear, and an electrical / mechanical vibration transducer is attached
to the floor and the foot, buttocks etc directly I feel the vibration and make an effect.

The electrical-mechanical vibration converter will be described with reference to FIGS. 8 to 11.
The external shape of the electric-mechanical vibration converter 1 used here is a concave case 2
covered with a thin plate 3. The case 2 is provided with a mounting hole 2a and a lead wire 4 is
connected. The lead wire 4 is connected to a cylindrical coil 5 fixed at the center of the plate 3. A
plate-like damper 6 is mounted on the inner periphery of the case 2 and an annular yoke 7 and
an annular magnet 8 are suspended. That is, an annular yoke 7 is attached to one surface of the
annular magnet 8, and a yoke 9 having a convex cross section is attached to the other surface of
the magnet 8. The convex portion 9 a of the yoke 9 is inserted into the inner hole of the magnet
8 to form an annular gap. The coil 5 is inserted into the annular gap.
[0004]
When a signal current flows through the coil 5, a magnetic field is generated, and the yokes 7, 9
and the magnet 8 repel the magnetic field. Therefore, if the electric-mechanical vibration
converter 1 floats in the air, the case 2 side will be positionally fluctuated by vibration centering
on the magnet 8 side having a large mass. As the relative vibration, even when the case 2 is
attached to the vibration receiving body, the amplitude shape on the magnet 8 side is almost the
same, so that the vibration can be generated efficiently following the signal current.
[0005]
By the way, when the electric / mechanical vibration transducer is mounted on the chair in the
listening room, it is necessary to manufacture a dedicated chair since it is embedded in the chair.
Therefore, arranging the number of chairs is expensive and opening a listening room is not easy.
On the other hand, portable cassette decks now allow users to easily play back tapes and listen to
music. Therefore, rather than sitting still in the above-mentioned chair, there are cases where you
can listen to music on the earphone as BGM while doing something. In this case, there is no
problem of sitting on a dedicated chair, but there is a problem that the sensation of reality is not
obtained and the realism is halved.
[0006]
Even in the above-mentioned aerobics classroom, each person can exercise aerobically in
accordance with the music while listening to the different music. However, in this case, it is
13-05-2019

unsuitable to use an electrical-mechanical vibration transducer attached to the floor. Also,
wearing a large vibration device on the body deprives the body of freedom.
[0007]
In addition, as shown in FIG. 12, there is one in which a small-sized electric / mechanical
vibration converter 1 is housed in a bag 10 so that it can be carried anywhere, but it is possible
to obtain sensation vibration while touching with palms, body and chair There is a troublesome
use that the user must positively press the bag against the body in such a way as to obtain a
sensational vibration by sandwiching it between them. In addition, the means of listening to
music is also restricted for that purpose.
[0008]
Besides, when listening to music outdoors, a portable cassette deck is often used, but it is not
easy to use earphones in places where vibration noise is high, such as in a train, and if the sound
is made louder it will Noise may result.
[0009]
SUMMARY OF THE INVENTION The present invention is an easy-to-wear type sensation
vibration device for converting sounds in the audible range into electrical sound signals and
enabling each person to easily feel the vibration caused by the sound signals by inputting the
sound signals. Intended to be provided.
[0010]
SUMMARY OF THE INVENTION In order to achieve the above object, the present invention
generates vibrations substantially along the waveform of an audio signal to an audio signal
obtained by electrically converting audio in the audible range in a bag to be brought into contact
with the body. And the vibration surface of the electric / mechanical vibration converter is built
in along the bag surface facing the body, and the electric / mechanical vibration converter is
provided with an input end of an audio signal, The bag is characterized in that a belt is attached
to the bag so as to be mounted in close contact with the body.

In the above-mentioned bag, when the bag member to be sandwiched between the electric /
mechanical vibration converter and the body is hard such as plastic, metal, etc., between the
electric / mechanical vibration converter and the bag member Fix so that chattering noise does
not occur due to vibration.
In addition, when using soft leather, fabric or soft materials such as sponges, thin ones are used
to reduce vibration damping.
[0012]
The belt attached to the bag is characterized in that it is an adjustable belt having a length for
tightening the easy-to-wear type sensation vibration device to the arm, the abdomen, the leg and
the like.
In addition, it may be a combination of this belt and a length-adjustable shoulder belt, or may be
a combination of two similar belts.
[0013]
Since the present invention is configured as described above, the bag is placed on the body and
the belt is tightened with a belt so as to be closely fixed. Therefore, the easy-to-install type of
bodily sensation vibrating device can be worn even on clothes.
Therefore, the vibration of the electro-mechanical vibration transducer is directly transmitted to
the body without being influenced by the movement and behavior of the body. Also, conversely,
the belt position can be changed and worn so as not to impede movement and behavior of the
body. And, when listening to music, you can enjoy sitting in a chair of your choice, regardless of
the posture of your body.
[0014]
In addition, when worn on the upper arm, there is little bodily sensation vibration to the body

such as the chest, and the stimulation to the brain is transmitted directly from the shoulders, so
the impact by the movement of the foot during walking does not interfere. In addition, the
shoulder belt can be stably attached to the waist, in which case the sensation of vibration is
transmitted to a wide area of the chest and back, so that a sensational vibration can be obtained
almost all over the body. In addition, when worn on the thighs of the legs, when standing, it is
possible to feel in preference to other vibrations of the feet.
[0015]
DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention will now be described
by way of example with reference to the accompanying drawings. As shown in FIG. 1, the easy-toinstall type bodily sensation vibration device 11 incorporates an electric / mechanical vibration
converter 1 in a bag 13 attached in close contact with the body 12, and the electric / mechanical
vibration converter 1 is a sheet 14. And the other gap is filled with the cushion 15. The lead wire
4 is drawn from the bag 13 and connected to an amplifier (amp) output. Further, a belt 17 is
provided by mounting brackets 16 attached to both sides of the bag 13.
[0016]
In the case of the hard plastic bag 13, the electric / mechanical vibration converter 1 can be
easily fixed by bringing it to one side, and the sheet 14 is interposed to prevent a chattering
noise during vibration. In addition, the cushion 15 damps the vibration on the opposite side.
Besides, the bag 13 is made of cloth, soft leather or similar soft one so that it can be fitted to the
body at the time of wearing, and the generated vibration can be transmitted to the outside
through these.
[0017]
By the way, in order to vibrate the electric-mechanical vibration converter 1, an amplifier, a
sound source, and a battery are required, and these are accommodated in another bag and
attached to the waist by a belt. In addition, by fixing the bag 13 on the plane of the belt 17, the
manufacture can be facilitated (see FIG. 2).

The belt 17 is attached to the bag 13, and the length of the belt 17 can be adjusted so that the
bag 13 can be applied to each part of the body. As shown in FIG. 3, when the bag 13 is closely
fixed to the upper arm of the body 12, the lead wire 4 of the electric-mechanical vibration
converter 1 is to be turned through the shoulders to the waist, but the lead wire 4 is removed
and the antenna is removed. 18 can be attached to make it cordless. In this case, the bag 13
accommodates a small receiving amplifier and a battery. Besides this, light (infrared ray or the
like) may be used as the medium as the transmission means. Also, by mounting a portable
cassette deck, the signal source can be self-supplied.
[0019]
Then, when an audio signal such as music or an impact sound is input to the electric-mechanical
vibration converter 1 built in the bag 13, the upper arm experiences a vibration. In addition, the
stimulation by vibration becomes partial, and most of the stimulation is transmitted from the
shoulder to the brain, so it is effective when you are moving the foot, such as walking, and
change the degree of feeling by concentration on the arm. Can. In addition, the body is hardly
restrained simply by tightening the upper arm with the belt 17, so that movement and action of
the body can be freely performed, and vibration can be felt, and depending on the posture of the
body, for example, when listening to music. Also, you can enjoy sitting in the chair you like.
[0020]
The easy-to-install type bodily sensation vibrating device 11 shown in FIG. 4 has a shoulder belt
19 in addition to the belt 17 attached to the bag 13. Each end of the shoulder belt 19 is attached
to the belt 17 and the bag 13. When the easy-to-install type of bodily sensation vibration device
11 is attached to the body 12, the bag 13 can be easily applied to the waist position (see FIG. 5).
And, because the vibration due to the audio signal is transmitted from the waist, the bone
conduction such as the hip bone and the spine is good, and it is easy to obtain a sense of
presence in the whole body. Also, in this belt structure, as shown in FIG. 7, the bag 13 can be
applied to the chest position. The sensational vibration in this case is also transmitted to the ribs,
and the same stimulation is transmitted to the brain to strengthen the sense of reality and to
promote a feeling of jealousy, tension and the like.

Further, the simple-fit type bodily sensation vibrating device 11 shown in FIG. 6 has a belt 17
attached to the lower part of the bag 13, an insertion band 20 provided on the upper part, and
the waist belt 21 passing through the insertion band 20. As shown in FIG. 7, when the bag 13 is
attached to the thigh, the stimulation due to the vibration becomes partial, but when standing on
the ground, the stimulation of the sensational vibration from the bag 13 causes the vibration
from the ground to Stimulation can be reduced, for example, when riding on a train and listening
to the music of a cassette tape, if the easy-to-wear type sensation vibration device 11 is attached
to the thigh, vibration stimulation due to running of the train is reduced and other sounds You
can easily listen to music without being disturbed by
[0022]
In the easy-to-install type of body sensation vibration device 11 described above, as an audio
signal to be input to the electric-mechanical vibration converter 1, an audio signal processed by
applying a low-pass filter to audio and a single frequency (50 to 350 in the bass region) There is
an audio signal which is modulated by an envelope signal which communicates the amplitude
height of the audio). Since the former does not have high frequency vibration, it is possible to
sense the vibration stimulation more sensibly. Further, the latter can sense continuous vibration
even if the low-pitched part is intermittently dropped when the voice is simply converted into an
electric signal.
[0023]
From the above, when it is used for music appreciation, it is possible to enjoy it in a light posture
only by wearing the bag on the body without needing a dedicated sensation vibration chair. Also,
in the aerobics classroom, a large facility for bodily sensation vibration is not necessary, and each
person can freely exercise according to different songs.
[0024]
As described above, since the easy-to-wear type bodily sensation vibration device 11 can be
easily attached to a part of the human body, it can be widely used in places of life. For example,
when the head is not clear, the easy-to-wear type sensation vibration device 11 is attached to the
13-05-2019

head to feel the looseness of the musical deep bass and to feel the vibration, and it becomes clear
while feeling the vibration. Use as purpose. In addition, when practicing musical instruments in
ordinary homes, the sound volume can be lowered by feeling the musical sounds by vibration,
and it can be used easily in a headphone sense.
[0025]
In addition, when playing sports, a signal for input is taken out from the dynamic music, and if
the user wears the easy-to-wear sensation transducer 11 worn on the body by this signal, the
sound from the speaker will act as accompaniment. It is possible to maintain concentration than
accompaniment. It is also possible to use vibration to transmit the timing of breathing. In
addition, by using the waterproof type of the easy-to-wear type bodily sensation vibrating device
11, it can be carried in water. In particular, in the indoor pool or the like, the sound of the
speaker is reflected and not clear, but it is possible to clearly transmit information such as the
rhythm of the music by giving it a vibrating sensation in water.
[0026]
In addition, the attachment position of the bag 13 in said usage can be attached to arbitrary
positions, since the bag 13 is small, It can mount | wear to a suitable location. Furthermore, it can
be mounted at a position that does not impair the degree of freedom of the body, and can also be
mounted in a plurality.
[0027]
As the present invention is configured as described above, the easy-to-wear type bodily sensation
vibration device can be fitted to any part of the body so as to be convenient for movement and
behavior of the body. . This makes it possible to feel the vibration of the sound signal of the
sound as well as the sound coming in from the ear. In addition, when the body is relaxed,
depending on when it is active, it can be used freely for multiple purposes by adjusting the sound
signal that generates vibration to the situation at that time.
