DESCRIPTION JPH05300591
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
sheet used under a pillow, which incorporates a flexible thin voice generating means using an
electroacoustic transducer, and has a low volume per unit area. It is an object of the present
invention to obtain a sheet which gives a sensible sound to a person who has a large sound
generation area and who is lying down.
[0002]
2. Description of the Related Art For persons who do not like wearing headphones or earphones,
for example, Japanese Laid-open Utility Model Application No. 60-185951, Japanese Laid-Open
Utility Model Application No. 60-185951 is intended to introduce a speaker into a bed to listen
to music etc. 62-183756 and the like. However, since there are few people who want to listen to
music by installing such a large-scaled device, the above-mentioned speaker built-in beds have
not been widely spread generally. Such a thing with a speaker attached to a pillow avoiding large
things such as a bed is known, for example, in Japanese Utility Model Application Nos. 1-4265, 1143969, and 2-98749. However, in the case of such a pillow-incorporated speaker, the human
being is not in an impatient posture even during lying down, and sometimes has a tendency to
change his posture unconsciously, and the speaker Not only does it have the drawback that the
volume is not constant due to the ear getting close or away, sometimes sometimes the sudden
loud sound can be heard and amazed by the bed so that the speaker's position feels "eary" There
are many cases.

PROBLEM TO BE SOLVED BY THE INVENTION It is possible to eliminate the disadvantage that
the sound emitted from a small area such as a pillow does not give a human a uniform volume,
and to obtain a volume which is not affected by the change of posture and to take one step
further The voice can be perceived as “ambient voice” coming from a vague, “fuzzy” sound
source, and you can enjoy music etc. and also use the psychological “peace of mind” derived
from the above “ambient voice” The purpose is to apply to psychological treatment and to
enhance its therapeutic effect.
[0004]
SUMMARY OF THE INVENTION The present invention comprises two layers of fiber material and
flat sound generating means sandwiched between them, and the above sound generating means
incorporates a thin electro-acoustic transducer. A flexible resonance plate surrounding the
electro-acoustic transducer and resonating with the element, the resonance plate having an audio
circuit formed independently on each of the left and right sides, and the electricity in the circuit
An acoustic conversion element is connected, and a fiber material covering the sound generating
means is composed of a surface layer material and a back layer material, and the surface layer
material and the back layer material are close to each other in a substantially parallel plane. Or
the above-mentioned sound generating means and buffer material, and is formed in the shape of
a flexible sheet.
Further, the resonant plate has a central separation zone having a void, and the void forms a
vibration blocking portion for blocking transmission of vibration, and the surface layer material
and the back layer material are peripheral portions Are connected to form a closed bag-like body,
and the closed bag-like body has an opening means by means of a linear opening / closing
member, and the above-mentioned sound generating means is held insertably / removably in this
inside, Further, an example of the electroacoustic transducer is a thin flexible electrostrictive
element, an example of the linear opening and closing mechanism is a slide fastener, and an
example of the linear opening and closing mechanism is a loop. It is a self-made flexible
detachable tool (commonly called Magic tape, registered trademark).
[0005]
In the present invention, since it is configured as described above, the following effects can be
04-05-2019

obtained. Humans have a tendency to change their posture unconsciously during lying down, and
the speaker built-in pillow has the drawback that the relative position between the speaker and
the ear is not constant, and the volume is not constant, sometimes when lying asleep The ear may
be surprised when approaching the speaker. In the present invention, the sheet-like structure to
be used below the pillow is incorporated, and a thin sound generation means using an
electrostrictive element or the like is built in, and the synergetic effect with the effect of
"atmosphere sound" described below Gives the ear a sound without fluctuation. In other words, it
gives "silence" as a sound that is not "early".
[0006]
The above-mentioned thin voice generating means comprises, for example, an electrostrictive
element and a resonant plate surrounding the electrostrictive element, and has a large total area
of voice generation, for example, an area larger than the surface area of a pillow. The generated
volume per unit area is a weak volume, and the total volume of the total area is not a large total
volume as will be described later in the embodiment, so the volume per unit area becomes
extremely weak.
[0007]
If it is calculated how much the sound becomes weak, in the case of the conventional pillowembedded speaker, the total area becomes 8 cm @ 2 if one each is 2 cm.times.2 cm.
In contrast, in the present invention, when the sound generating means of 30 cm × 35 cm is
used on the left and right sides, the total of 2100 cm 2 is obtained by setting 30 cm × 70 cm. If
the volume is equal to that of the conventional pillow type, the required volume per unit area
may be about 1/262 since the required volume is inversely proportional to the area. Because of
the weak volume, it can not be determined where the sound source is, and the human feels that
the sound comes from a vague "fuzzy" sound source and will be perceived as "atmosphere
sound". As a result, human beings are given psychological "peace of mind". By applying this
“peace of mind”, you can enjoy relaxing and relaxing music, and relaxing and relaxing can be
introduced to sleep, and various kinds of psychotherapy recordings currently marketed in the
market. It is also possible to carry out psychological treatment using a group such as CD, CD and
the like.
[0008]

As in the above calculation, the volume per unit area becomes weak and the sound source
becomes "fuzzy". However, since each area on the right and left sides is blocked and is a separate
area, it is separately sensed as the total volume of the right region and the total volume of the left
region in the experiment, and commercially available stereo music recording According to his
experiments, humans were able to enjoy magnificent stereo music by good stereo sound, such as
music coming from a three-dimensional space. It is commercially available (including radio
broadcasting etc.). The same shall apply hereinafter) but it is considered that the ambience sound
has become a "three-dimensional ambience sound" due to the synergetic action with the
ambience sound of the present invention.
[0009]
EXAMPLE 1 FIG. 2 is a perspective view showing the state of use of the example of the present
invention, which is used by appropriately laying a cloth on the mattress or the bed 50. As shown
in FIG. Under the pillow 5 is a sheet 1 of the present invention. The pillow 5 is the size of a pillow
generally used, and has a general size of 25 cm × 40 cm (in plan view). In comparison, the sheet
1 has a size larger than that of the above-mentioned general pillow, and has a size of 35 cm ×
80 cm in a plan view.
[0010]
FIG. 3A is an explanatory view for explaining an arrangement example of the electroacoustic
transducer, for example, the electrostrictive element 8 disposed inside the voice generation
means 7. At least one electrostrictive element 8 needs to be disposed at each of the left and right
sides. In this embodiment, a total of four electrostrictive elements 8 are disposed, two each for
the left and right sides. Since these four need not necessarily be arranged in one row, in the case
of the figure, an example is shown in which they are arranged in a zigzag. The arrangement of
this will be described along the dashed line X... X as shown in FIG. 3 (b). In the figure, reference
numeral 10 denotes an air gap, which separates the left and right sound areas as a central
separation band and blocks the vibration. This causes the right and left resonant plates to vibrate
independently, producing an effect of emitting sound as a stereo. In FIG. 3 (b), the thickness is
drawn in an enlarged manner, and in particular, the thickness of the electrostrictive element is
drawn in an enlarged manner. In addition, the above-mentioned electrostriction element 8 shall
generically refer to the element of the system which produces distortion by voltage application.

[0011]
FIG. 3 (c) is a front view and a rear view of the sheet 1 constituted by the closed bag-like body 6
described later, and FIG. 3 (d) is a side view, which appears symmetrical. Both show the
appearance which looked at flat sheet 1 from the horizontal direction. FIG. 3E is a plan view and
a bottom view of the flat sheet 1. Openings by known linear closures such as fasteners may be
provided in any part of the sheet 1 and thus are not shown, but, for example, in addition to the
positions such as the dashed line 11, generally closed bag-like members According to the
example of the linear opening and closing means provided on the sheet, it is provided at an
appropriate position (which may be the front side or the back side of the sheet). The electric wire
12 drawn from the audio circuit may be drawn from any position, but FIG. 3E shows an example
in which the electric wire 12 is drawn using a portion (opening) of the dashed line 11 which is an
opening. As described above, the position of the opening may be any position.
[0012]
FIG. 1 (a) is a cross-sectional view showing a state in which the broken line portion 14 of FIG. 3
(b) is enlarged and sandwiched between a surface layer material and a back layer material
(described later). The voice generation means 7 sandwiched between the surface layer material 3
and the back layer material 4 (described later) has a flexible electrostrictive element 8 which may
be made of an elastic foam resin (for example, urethane foam). The flexible resonant plate 9
surrounds (embeds in) the periphery, and both the resonant plate 9 and the electrostrictive
element 8 are bonded so as to be in close contact with each other. Therefore, when the
electrostrictive element 8 is vibrated by the voice signal, the bonded resonance plate 9 is also
vibrated, and according to the experiment, it was confirmed that the vibration (wave) was
transmitted to a distant position and resonated. Since this resonance plate 9 is formed to have a
large dimension, for example 70 cm, of the left and right dimensions as compared to the pillow 5,
the sound wave is sent to the ear from the left and right of the pillow 5 without being disturbed
by the pillow 5. Even if it penetrates the pillow 5, it reaches the ear. The voice generation means
7 is divided by a central separator (described later) and vibrates independently. As such, in order
to vibrate left and right separately in stereo, it is connected to audio signal circuits (not shown)
formed independently on the left and right respectively. The lead 12 of the audio signal circuit
may be directly connected to a recorder or a CD, or the user may appropriately add and use a
wire, a jack or the like. The central separation zone 10 is a gap provided at the center of the
resonant plate 9 and acts as a blocking portion for blocking vibration, and the resonant plate 9
vibrates independently to the right and to the left. Reference numerals 7a and 7b denote cloths
covering the resonance plate. The electrodes 8a and 8b of the electrostrictive element 8 are
connected to the above-described audio signal circuit. As a sound source device of an audio
04-05-2019
5
circuit used for the audio generation means, any type of device such as a small CD or a small tape
reader can be used. According to the experiment, even if the volume is small, it can be heard, so
in the case of a large model, the volume control is used as "weak".
[0013]
The substantially parallel flat surface layer material 3 and the back layer material 4 which form
the sheet 1 are formed of a fiber material (for example, cotton of synthetic fibers), and both the
surface layer material 3 and the back layer material 4 are mutually Adjacent to each other, the
above-mentioned sound generating means 7 is sandwiched between the two. The surface layer
material 3 and the back layer material 4 approach each other as they are parallel flat, and only
the bonding portion 2 at the peripheral portion is, for example, the bonding portion 2 in FIG. 1
(b) and FIG. 3 (e). As a whole, the closed bag-like body 6 is formed, and the appearance forms a
flat sheet 1. Reference numerals 3a, 3b, 4a and 4b denote cloths covering the surface layer
material 3 and the back layer material 4, respectively. As described above, in the present
embodiment, the surface layer material 3 and the back layer material 4 are covered with a cloth,
but they may be cloths not requiring covering such as woven products, knitted products and nonwoven fabrics. , And cotton cloth, etc. shall be selected and used. In that case, the hippo-3a, 3b,
4a and 4b are unnecessary. The distinction between the above-mentioned front and back is not
strict, but rather the front and back also have common structure, so it is left up to the user to
decide which side to use as the front.
[0014]
As shown in FIG. 3 (e), the surface layer material 3 and the back layer material 4 are joined by
the joint portion 2 to form the closed bag-like body 6, but the dimensions of the closed bag-like
body 6 and the sound generating means 7 The dimensions of are roughly formed. The broken
line 7a shows the outline of the voice generation means 7 accommodated inside.
[0015]
The sheet 1 formed as the closed bag 6 has an opening mechanism (described later) by a linear
opening and closing member, and the voice generating means 7 is inserted into the sheet 1 and
held so as to be removable. As a result, the appearance of the closed bag-like body 6 forms a flat
sheet 1 with a flat surface. The sheet 1 may be placed under the pillow 5 as shown in FIG. 2, or
04-05-2019
6
under a bed cloth, or under a futon. In addition, as a method of free use of the user, for example,
it can be used by putting it on a pillow, placing it in the vicinity of the ear, listening, or using it
outdoors. In particular, when used for medical purposes, the effect is large, and in that case, it
can be applied to various kinds of psychological treatment to enhance the treatment effect while
giving psychological "peace of mind".
[0016]
As means for opening the above-mentioned closed bag-like body 6, a linear opening / closing
mechanism (not shown), for example, a slide fastener is provided at an optional position (not
shown). The dashed line 11 is an example of the position. FIG. 3 (e) shows an example in which
the electric wire 12 is drawn out from the opening (dotted line portion) of the closed bag 6 (sheet
1).
[0017]
As means for opening and closing the above-mentioned closed bag-like body 6, it is also possible
to provide a linear opening and closing mechanism (not shown), for example, a loop dense
flexible type detachable attachment (magic tape, registered trademark) at any position not
shown. it can. The drawing uses FIG. 3 (e), and the dashed line 11 is an example of the position of
the opening. The drawing shows an example in which the electric wire 12 is pulled out from the
opening portion (the portion of the chain line 11) of the closed bag (sheet 1).
[0018]
Example 2 In the above Example 1, the sheet 1 was described as being placed under the pillow 5,
but an extra area of fibrous material may be added to this sheet 1, in which case the extra area is
By adding it, it becomes like bedding, and a voice generation sheet with a feeling like bedding can
be obtained. FIGS. 4 (a) to 4 (e) show that the closed bag-like body of the first embodiment is
added with a bedding material that can reach the foot and is formed on the lining 21 and extra
bedding material is also added on the left and right. The broken line 50 indicates a mattress, a
futon, etc., and the sheet 1 is used on it. Accordingly, the appearance becomes like bedding, and
the sound generation means need only have an area that can fall within the range of the closed
bag area 6a inside the broken line 7a, and the remaining part, ie the part 22 other than the
closed bag area 6a It may be a simple fiber material having no means of sound generation. For
04-05-2019
7
the same reason, the area of the closed bag region 6a may also be the same size as or slightly
larger than the broken line 7a, and the remaining portion 22 is not a bag but a simple single
layer of fiber material as described above. It is also good. The single-layer fiber material may be,
for example, a woven product, a knitted product, a non-woven fabric, or the like suitable for
bedding such as a bed cloth, a futon, a blanket, a cotton cloth and the like. Although the figure
shows a cloth that can reach the foot, the area may be small, for example, it may be a small area
covering a dirty portion near the head (such as spilling food and staining it). In FIGS. 4 (a) to 4
(e), the parts common to the first embodiment are denoted by the same reference numerals, and
the description of the parts common to the structure, operation, and use state is omitted. Further,
since the voice generation means 7 of FIG. 3A is common to the second embodiment, the drawing
is omitted. However, in FIG. 4 (c)-(e) shown as the second embodiment, the vertical and
horizontal relationship is reversed compared to FIGS. 3 (c)-(e), and the front view of FIG. 3 is a
side view in FIG. It becomes a figure, and the side view of FIG. 3 is a front view in FIG.
[0019]
In addition to the voice generating means described above, the addition of an extra material is
optional, such as inserting a core material of an elastic foam, for example, inside the bag of the
closed bag 6 or 6a.
[0020]
Example 3 Although a linear switch material was used in Example 1 described above, this
example does not use a linear switch material as compared to Example 1.
With the exception of not using the linear opening / closing material as described above, the
same effects can be obtained by acting as described in the above-mentioned [0005] to [0008].
FIG. 5 is an explanatory view showing a use state of the embodiment shown in FIG. 6 (b)
described later, and the thickness is omitted. In FIG. 6A, the surface layer material and the back
layer material are joined (in this case, stitched) at peripheral portions 2 of three sides, and
formed in the pocket 31. In this case, the pocket 31 corresponds to the closed bag 6 of the first
embodiment. The three sides are joined, and the remaining one side is an opening 11a which
remains open. The above-mentioned sound generation means 7 (not exposed) is inserted in the
direction of arrow A from the opening 11a, and only the electric wire 12 is exposed in the figure.
Parts common to the first embodiment will be denoted by the same reference numerals, and the
description thereof will be omitted to obtain similar effects.

[0021]
Although this state can be sufficiently used, an extra fiber material may be added in addition to
the area of the pocket 31 in order to further add to the convenience of use. FIG. 6 (b) is an
example thereof, and the pocket 31 incorporating the sound generating device 7 (not shown) is
additionally provided with an extension cloth 5b as an extra fiber material. If the end of the
extension cloth 5b is held by hand and turned to the back of a mattress, futon or the like, the
pocket 31 can be held in a stable position as shown in FIG. FIG. 6C shows an example in which an
extra extension cloth 5c is added to the entire circumference. As a modification of FIG. 6 (c), the
extension cloth 5c may not be the entire circumference but may be only a part, or a type which
extends left and right only from the two left and right sides of the pocket and does not extend at
all in the vertical direction It may be In any case, by adding the extension cloth, the position of
the pocket 31 can be fixed, and in addition, it can be easy to get dirty on the bed 50, mattress,
mattress etc. especially in the vicinity of the head. Produces the effect of covering food spilling
parts and the like and preventing contamination in advance. In addition, since the pocket of each
said form is used in a horizontal state on a bed etc., unlike the pocket of clothes, since the
contents (sound generating device 7) do not fall by gravity, the opening of the opening part The
direction may ignore the relationship between right and left and upper and lower, and may be
right open, left open, upper open, or lower open.
[0022]
FIG. 7 is an explanatory view showing a use state of the embodiment shown in FIG. 8 (b)
described later, and the thickness is omitted. In FIG. 8A, the surface layer material and the back
layer material are joined (in this case, stitched) at the peripheral edge 2 of two sides, and are
formed in the bottomless pocket 41. In this case, the bottomless pocket 41 corresponds to the
closed bag 6 of the first embodiment. The two sides are joined, and the remaining two sides are
an opening 11b which remains open. The aforementioned sound generation means 7 (not
exposed) is inserted as shown by arrow A from the opening 11b, and only the electric wire 12 is
exposed in the figure. Also in this type, parts common to the above embodiment are denoted by
the same reference numerals, and the description thereof is omitted, and the same effect is
exhibited.
[0023]
Although this state can be sufficiently used, an extra fiber material may be added in addition to
04-05-2019
9
the area of the bottomless pocket 41 to further enhance the convenience of use. FIG. 8 (b) shows
such an example, and an extension cloth 6b is added as an extra fiber material to the outside of a
bottomless pocket 41 incorporating a sound generation device 7 (not shown). When the end of
the extension cloth 6b is held by hand and turned to the back of a mattress, futon or the like, the
bottom pocket 41 can be held in a stable position as shown in FIG. FIG. 8C shows an example in
which an extra extension cloth 6c is added to the entire circumference. As a modification of FIG.
8 (c), the extension cloth 6c may not be the entire circumference but may be only a part, or a
type which extends left and right only from the two left and right sides of the pocket and does
not extend at all in the vertical direction It may be In any case, the addition of the extension cloth
has the effect of fixing the position of the bottomless pocket 41, and further, the dirt prone
portion such as a bed, mattress, or futon, such as 50, especially the head It produces the effect of
being able to prevent contamination in advance by coating the area that spills food etc. in the
vicinity. In addition, since the pocket of each said form is used in a horizontal state on a bed, a
futon, etc., it differs from the pocket of clothes, and since the content (sound generating device 7)
does not fall by gravity, it is an opening part The direction of the opening may ignore the
relationship between the left and right and the upper and lower, and may be either left open or
open.
[0024]
The parts common to the first embodiment, such as the voice generating means 7 inserted into
the pocket 31 or the bottomless pocket 41, the electric wire 12, etc. use the same reference
numerals and the explanation thereof is omitted.
[0025]
Of the above-described embodiments, the excess fiber material 22, 5b, 5c, 6b, 6c for the closed
bag-like members 6, 6a and the pockets 31, 41 are all extra areas outside the voice generating
device. Use this area to attach and place a small pocket (compared to the above-mentioned
pocket for storing the voice generator and a closed bag-like body) for storage of portable goods
in this area, dust paper, comb, etc. In addition to various daily necessities, as small-sized handheld products, it is also possible to store arbitrary small articles such as small change, telephone
cards and the like.
FIGS. 9 and 10 show an example thereof, and instead of the pockets 31 and 41 described above,
an extension cloth corresponding to the above-mentioned extension cloth 6c (or 5c) as indicated
by a reference numeral 7c for a pocket indicated by a reference numeral 51. 7c is provided, and
the pocket 45 for putting in a belonging is attached to the part. This makes it possible for the
04-05-2019
10
patient on the bed, especially the bedridden sick person, to manage it at my own hand much
more safely than putting it on a bed or bed which is easy to fall down. In addition, although the
pocket was drawn sideways in the figure, it is not limited to sideways, You may open in any
direction. The pocket attachment place is not limited to the hand of the left hand as shown in the
figure, and may be provided at any place of the extra fiber material 7c.
[0026]
Embodiment 4 FIG. 11 shows a fourth embodiment. In the figure, the voice generation sheet 21a
is obtained by thickening the appearance of the cloth 21 shown in FIG. 4A as the second
embodiment described above. . Except for the fact that the thickness of the appearance is thicker
than in FIG. 4 (a), the others are not changed. As a means for increasing the thickness, as shown
in FIG. 12, a buffer material 30 is added under the voice producing means 7. Therefore, the
thickness of the backing layer 4 may be reduced because the thickness may be reduced. If the
cushioning material 30 is made thicker, the appearance becomes thicker. The buffer material
may be, for example, a fiber material, but the fiber material overlaps with that of the second
embodiment. If a shock absorbing material other than a fiber material is used, for example, a
foam elastic material such as a foamed resin is preferable as a typical shock absorbing material.
The figure depicts the cushioning material 30 as a foamed elastic material.
[0027]
In FIG. 13, a shock absorbing material 30 is provided also on the upper side of the voice
generation means 7. By adding the shock absorbing material 30, the surface material 3 can also
be made thinner. In the state of FIG. 13, if the buffer material on the upper side of the voice
producing means is omitted, for example, it becomes as shown in FIG.
[0028]
In the fourth embodiment, the voice generation means 7 is provided in the vicinity of the head of
a human as in the second embodiment described with reference to FIG. , It may be just bedding.
Parts common to the first to third embodiments will be denoted by the same reference numerals,
and the description thereof will be omitted. In the second embodiment described above, the
closed bag-like member 6a is provided as a means for maintaining the voice generation means 7
in a fixed position, and is held so as to be insertable and removable. In the case of providing a
04-05-2019
11
shock absorbing material, the voice generating means 7 is attached to the foamed elastic material
30, sewed, tied with a string, or a loop-dense type removable tool (commonly known as magic
tape, registration The sound generating means 7 may be held by any holding means, such as
using a trade mark to releasably hold the sound generating means 7, or may be held using a
closed bag.
[0029]
Since the speech generation sheets of the various embodiments described above have the abovementioned effects, the user can be used for a desired application according to the lifestyle of
each person. Although the form of use and the method of use are free to each person, only three
examples among examples of application are listed as FIG. 15, FIG. 16 and FIG. 17 for reference,
but are not limited to these three examples. . FIG. 15 shows the case of use on a bed 40, and FIG.
16 shows the case of use on a fenced bed (eg baby bed) 60, and FIG. 17 shows a seat 70 folded
around a person's waist. It is an example used as When it uses for a seat chair like FIG. 17, the
pillow 5 is unnecessary like a figure.
[0030]
As described above, according to the present invention, since the volume per unit area is
extremely weak and sound is generated from a wide area, it is possible to determine where the
sound source exists because of the weak volume per unit area. In addition, human beings can be
given psychological “peace of mind” because they are felt as coming from vague “fuzzy”
sound sources and perceived as “atmosphere speech”. As a result of this kind of “peace of
mind,” you can enjoy relaxing and relaxing music, and relaxing and relaxing can be introduced
to sleep, and various kinds of psychotherapy recordings currently marketed in the market. You
can use psychotherapy, CD, etc. to improve psychological effects. Further, by using a known
stereo sound source together with the present invention, the effect of the atmosphere sound can
be further enhanced to obtain "atmosphere three-dimensional sound".
