[0002]

2. Description of the Related Art For a person who does not like wearing headphones or earphones, a speaker is incorporated in a bed to allow a lying person to listen to music or the like.
0-185951, S. Kaikai 62-183756 and the like are known. However, since there are few people who want to listen to music even after installing such a large-scale device, the above-mentioned speaker-embedded bed has not been widely spread. As such a pillow with a speaker attached to it, avoiding a large bed or the like, there are known, for example, Real Kaihei 1-4265, Real Kaihei 1-143969, and Real Kaihei 2-98749. However, in the case of such a pillow with a built-in audio device, the pillow and the audio device are integrated, and the use is limited to when sleeping, and the heavy and bulky pillow is an obstacle for the use other than when sleeping. However, it has many problems such as it cannot be used at all in reclining sheets.

[0003]

[Problems to be Solved by the Invention] It is not impossible to carry like a pillow with built-in audio equipment, but it can be easily carried and traveled, and it is impossible to use a pillow such as a reclining seat. The purpose is to enable use in various places and to listen to complete stereo sound without using earphones or headphones.

SUMMARY OF THE INVENTION According to the present invention, two bag wall surface constituent members are connected to each other via a hinge-shaped portion, and a connecting plate-shaped body provided with a bag-shaped portion is formed. In a bag which is formed into a thin bag shape composed of two bag wall surface components by folding and folding in two,
A thin electroacoustic transducer having stereo electrical wiring for connecting to an acoustic device is embedded in a part of the area of a plate-like foam elastic material so as to resonately adhere to the foam elastic material to form a planar sounding body. The bag wall surface constituting material is one in which the planar sounding body is used as a core material and at least the outer surface of the bag is covered with a surface coating material. In addition, two bag wall surface constituent members are connected to each other through a hinge-shaped portion, and a connecting plate-shaped body provided with a bag-shaped portion is formed, and the connecting plate-shaped body is folded in two to be folded into two pieces. In a bag formed into a thin bag shape made of the bag wall constituent material, a thin electro-acoustic conversion element equipped with stereo electric wiring for connecting to an audio device is formed on a part of the area of the plate-shaped foam elastic material. To form a sheet-like sounding body that is in close contact with the material so as to resonate, and the bag wall surface constituting material comprises an exterior material and an interior material with the sheet-like sounding body as a core material. It is mounted so that it can be inserted and removed between the material and the interior material. In addition, two bag wall surface constituent members are connected to each other through a hinge-shaped portion, and a connecting plate-shaped body provided with a bag-shaped portion is formed, and the connecting plate-shaped body is folded in two to be folded into two pieces. In a bag formed into a thin bag shape made of the bag wall constituent material, a thin electro-acoustic conversion element equipped with stereo electric wiring for connecting to an audio device is formed on a part of the area of the plate-shaped foam elastic material. It embeds in close contact with the material so that it can resonate and is configured as a planar sounding body.
The bag wall surface component is made of a foamed elastic material having a dense surface, and the electroacoustic transducer is covered with the foamed elastic material to form the planar sounding body.

[0005]

In the present invention, since it has the above-mentioned structure, the following operation is achieved. The planar sounding body is composed of, for example, an electrostrictive element and a plate-shaped foamed elastic material that surrounds the electrostrictive element and resonates. The foamed elastic material emits sound from a large area having a large total sound generation area, for example, a large area corresponding to the wall surface of the bag. Therefore, the volume generated per unit area is weak, but there is an advantage that a large volume can be obtained as the total volume of the total area, and even a portable audio device with a small power capacity has a sufficient volume for the human ear. Is obtained.

Further, by using the sheet-like sounding body as the wall surface constituting material of the bag, the sheet-like sounding body itself serves as the wall surface of the bag. There is no need to attach a (speaker). If a speaker with such a large area is set for a conventional bag, that speaker
Mosquitoes should be remarkably large.

According to the above structure, when the above two sheet-like sounding bodies are folded in two at the hinge portion and folded together, the bag becomes a well-known two-fold type bag for carrying documents and personal belongings. Not only that, but when the audio device is a small-sized and portable device, the audio device can be stored in the bag and carried.

Compared to earphones and headphones used for general portable audio equipment, it is not necessary to wear it on the body (ear), so that the body is free and no unpleasant feeling is felt. However, as will be described later, since the left and right sounds are well separated, a more sufficient stereophonic sound can be obtained as compared with a stereo system in which two speakers are installed in the room for listening. Therefore, even people who do not like wearing earphones and headphones can listen to stereo broadcasts and CDs. The voice has a feeling of liberation because the device is not attached to the body. Since the area of the sound source is greatly expanded in the obtained sound, it is not possible to determine where the sound comes from, and according to the experiment,
I was able to enjoy stereo music as a magnificent voice coming from an elusive outer space.

At home, don't hesitate to spend time studying with your family.
At the hospital, the old man can enjoy listening to broadcasts and CDs without hesitating to the bed next to him, and the old man can increase the volume to his or her favorite volume without hesitating to go to the neighborhood. Moreover, as shown in FIG. 4, it is a "planar sounding body" that violates the conventional concept of a speaker, and it can effectively utilize a narrow space as a buzzword "wall hanging type".

It can also be applied to medicine. When using a commercially available recording tape for psychotherapy, CD, etc.,
Since no device is attached to the body (ear), it does not give a feeling of pressure to a nervous person who dislikes wearing earphones and headphones. In addition, as described above, the sound of an “ambiguous” sound source, which cannot determine where the sound comes from, is more sensitive to the presence of the speaker, as compared to the sound from a single point, such as commercially available audio equipment. Delicate-minded, which does not give discomfort to other people, facilitates psychotherapy, and enhances its effects.
A great effect can be obtained particularly when an attractive atmosphere is required.

Embodiment 1 FIG. 1 is a perspective view of this embodiment, in which a bag wall surface constituent member 3 is a hinge-shaped portion 2 formed of a bendable material.
Two pieces are connected via the, and when folded, it becomes a thin bag as shown in FIG. The connecting plate-like member 4 connected to the two pieces becomes as shown in FIG. 4 when it is expanded, and the connecting plate-like member 4 is folded in two and folded to be composed of two bag wall surface constituent members 3. It is configured into a known thin bag shape (FIG. 2). The bag wall surface component 3 is provided with an arbitrary number of bag-shaped portions 21 and the like, as described later, for accommodating thin belongings such as documents and memo papers, and sometimes a small radio, a CD player or the like. Be accommodated.

FIG. 3 is an explanatory view of the electric parts inside the bag wall surface constituting material 3, and the inside of the bag wall surface forming material 3 is exposed, and those not related to the electric parts are omitted in the description. The core material forming the wall surface of the bag is made of a flexible elastic foam material 8 (described later, FIG. 5), which is designated by reference numeral 7 in this figure. A hollow 18 is provided as a vibration isolation area in the central hinge 2 (folded portion) in order to convert the sound into stereo sound. Instead of the hollow 18, the hinge 2 is made thin. Vibration may be prevented from being transmitted. Two electroacoustic transducers 9 are bonded to the left and right with an adhesive and embedded as shown in FIG. 5 in a part of the area of the foamed elastic material 8 (reference numeral 7 in this figure). The foamed elastic material 8 is a resonator plate in which the electroacoustic transducer 9 is adhered to form an integrated resonator plate, which forms the planar sounding body 7. At least one electroacoustic conversion element 9 is required on the left and right sides, and the number may be more than two. The electric wiring 12 connected to an audio device (not shown) is stereo wiring of two left and right systems, and is wired at an appropriate position. Therefore, the right and left planar sounding bodies 7 are two systems of planar sounding bodies independent of each other. Although a case where an element that deforms by energization (for example, an electrostrictive element) is used as the electroacoustic conversion element is shown in the figure, a general electromagnetic coil speaker may be used. In the drawing, the electric wiring 12 is drawn up to the connection terminal portion, but it is assumed that the user appropriately connects to the electroacoustic equipment. Depending on the case, it can be used for the following purposes by connecting an amplifier or a repeater to increase the volume. For example, a transmitter may be installed on the TV side and a wireless receiver may be installed on the viewer side in order to watch the TV away from the TV, and the TV may be viewed (wired transmission / reception may be performed). A microphone with a transmitter (wireless microphone) is installed on the person side, an amplifier / radio receiver is installed on the audience side (or the venue side) for wireless transmission / reception (may be transmitted / received by wire), and used as a loudspeaker. It can be used for. In either case, the terminal of the electric wiring 12 is connected to the radio receiver or the amplifier for use.

FIG. 5 shows a cross section of the planar sounding body 7. In the figure, an electroacoustic conversion element 9 is embedded in a foamed elastic material 8 serving as a core material of the planar sounding body 7. Surface covering 1
4a and 14b are foamed elastic material 8 and electroacoustic transducer 9.
To form a planar sounding body 7. The planar sounding body 7 is covered with a surface coating material to form a bag wall surface constituting material 3 (FIG. 1) having a surface that looks like a bag wall surface. Although the electroacoustic conversion element 9 is not covered with the foam elastic material 8 in the figure, the entire surface of the electroacoustic conversion element 9 may be covered with the elastic foam material 8. Surface covering materials 14a and 1
The peripheral portion 4b is appropriately joined by a conventional method such as covering the peripheral edge portion 5 (FIG. 1) with a tape-like material and suturing. Therefore, the sheet-like sounding body 7 made of the foamed elastic material 8 has the surface covering materials 14a, 1
4b and the peripheral portion 5 (coupling portion) are surrounded and confined.

The surface coating material 14a extending to the outside of the bag is
For example, natural leather, artificial leather, leather cloth, woven fabric, knitted products, and the like, which are generally used for bag covering, are used as the inner surface of the bag 14b. Interior materials such as knit products may also be used. In this way, the surface coating materials 14a, 14b
The sheet-like sounding body 7 becomes a bag wall surface constituent material 3 having an appearance suitable for a bag by being covered with, and the appearance of the bag 1 having an outer surface for a bag as shown in FIGS. It is formed. If a foamed elastic material having a dense surface is used as in Example 3 described later, either of the surface coating materials 14a and 14b can be omitted. In that case, it becomes an eclectic type with the third embodiment.

As shown in FIG. 1, the bag portion 21 is placed at an appropriate position.
To provide. The position and the number of installation are arbitrary, and FIG.
Shows an example in which bag-shaped portions 21 and 22 are provided on each bag wall surface component 3, FIG. 11 shows an example in which a bag-shaped portion 23 that opens close to the hinge-shaped portion 2 is provided, and FIG. 13 shows a hinge-shaped portion. This is an example in which a bag-shaped portion 24 that opens at a position away from 2 is provided. The bag-shaped portions 23 and 24 may be single or plural, and 23 and 24 may be mixed. Although each bag is shown as being provided on the inner surface of the bag, it may be provided on the outer surface of the bag.

For convenience of use, the carrying hand 17 is attached so as to be provided in a general bag, but the position of the carrying hand 17 is not limited to the position shown in the figure, but is attached to the top of the bag, for example. May be. When used for the head of a reclining sheet, a belt 16 made of an elastic material may be provided so as not to slip.

Example 2 FIG. 6 shows Example 2, which is the surface coating material 14 of Example 1 above.
In order to show a state in which a and 14b are separated from the foamed elastic material 8, a space is intentionally formed between them.
However, in reality, the three come close to each other. The surface covering materials 14a and 14b are joined to each other at the peripheral edge portion 5 (FIG. 1) by a method such as stitching by a conventional method. In this way, when only the foam elastic material 8 is free from being bonded or sewn, the foam elastic material 8 can be freely separated from the surface covering materials 14a and 14b. FIG. 8 shows an example of means for inserting / removing the foamed elastic material 8, which is inserted / removed from an opening 10 provided at an arbitrary position. The position of the opening 10 is arbitrary, and may be, for example, the central portion (connecting portion) of the connecting plate body 4 as shown in FIG. In both FIG. 8 and FIG. 9, the opening 10 may be an opening with a fastener as shown in FIG. 8, may be without a fastener, and may or may not have a fastener. Further, the openings may have a superposed structure. An example thereof is shown in FIG.
Shown as 19b. A portion between the broken line 19b and the solid line 19a is a portion where the surface coating material is overlapped. When they are overlapped in this way, a fastener may be provided in the middle (between both pieces) where they are joined, in which case there is an advantage that the fastener cannot be seen from the outside. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

Example 3 FIG. 7 (a) is a sectional view showing Example 3, in which the surface coating materials 14a and 14b of Example 1 are omitted, and instead the elastic foam material itself does not need to be coated. It is a decorative material. In order to make the foam material itself a decorative material that does not need to be covered, the surfaces of the foam elastic materials 8a and 8b are made to be the dense surfaces 8c, and the foam elastic materials 8a and 8b are used as means for forming the dense surfaces 8c. It may be a stack of dense layers 8c, or may be a foam in which the bubbles in the surface layer are made dense so that the bubbles cannot be seen from the surface, or all the bubbles are microscopic and invisible to the naked eye. Foam may also be used. FIG. 7B shows an example in which the surface 8d is embossed to make it look like leather, and the other surface 8e may be similarly embossed. As an example of embossing, in addition to a leather shape, a woven shape, etc., an arbitrary uneven pattern (for example, unevenness imitating a speaker) may be formed. The same parts as those in the first and second embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The connecting means for folding the respective bag wall surface constituting materials 3 will be described through the first to third embodiments.
In FIG. 1, reference numerals 30 and 31 show an example of a connecting tool for bending the bag wall surface component 3 by bending at the hinge-shaped portion and connecting the bag wall component 3 to each bag wall component 3. Buttons and button holes (commonly referred to as hooks and snaps; the same applies hereinafter) 30 and 31 are provided in a portion distant from the portion, and both are joined by a conventional method. FIG. 12A illustrates an example in which a hook 32 for hooking is provided as a coupling tool, and FIG.
2 (b) is a loop dense type flexible attaching / detaching tool (magic tape).
(FIG. 12C) shows an example in which a tongue-shaped extension piece 35 is extended from one side and the other side is connected by a magic tape. Show. Instead of this magic tape, a button, a hook or the like may be used. In FIG. 12 (d), a stretchable belt 36 is provided on one side 3a of the bag wall surface component 3, and this belt 36 is rotated around the back side (the bag front side when folded) 3b of the partner bag wall component 3, This is an example of combining the two by the method. FIG. 12 (e) is an example in which carrying hands 37 and 38 are provided on each of the bag wall surface constituent materials 3, and both of them can be held by the hand at the same time by a common method. In addition to the above examples,
Appropriate coupling means may be used.

Through the above-described Examples 1 to 3, if the connecting plate 4 is folded in two and folded, a thin bag can be obtained. Not only can thin carrying items such as memos and documents be put in and carried, but also various kinds of bags can be carried. You can carry thin items such as small radios, combs, paper dust, and coins. When expanded to form the connecting plate 4, the entire surface becomes a stereo device, which can be laid under the pillow, placed on the pillow, attached to a reclining sheet, etc., and freely enjoy the stereo considering the application. You can It can also be used as a "wall-hanging" planar stereo or planar loudspeaker when increasing the volume by installing an amplifier as described above.

In each of the above-mentioned embodiments, a "washing replacement cover" may be added in order to make the inner surface of the bag replaceable (washable). For example, in addition to buttons and hooks on the inside of the bag, fasteners, magic tape, etc. are provided, and "washing replacement cover" (eg, white cloth)
Similarly, corresponding buttons, hooks, fasteners, and magic tapes may be attached to the side so that they can be attached to and detached from each other.

As one form in which the "laundry replacement cover" is provided, the "laundry replacement cover" itself may be used as a substitute for the "bag-shaped portions" 23, 24 described above. In that case, the "bag-shaped portion" represented by the reference numerals 23 and 24 in the above description and the drawings should be read as "washing replacement cover" for decoding, and the illustration is omitted. The bag-shaped portion in this case may be a pocket of a single cloth (bag material) or a pocket of a double cloth so that it is generally used for a pocket or the like. An example in which the "pocket" and the "laundry replacement cover" are combined is shown in FIG. 14, but the present invention is not limited to this example. In the figure, two bag-like bodies 24, 24 formed in a pocket shape with a double cloth piece are connected by a hinge-like portion 2 to
It is a series. Among the double cloth pieces, the single cloth piece on the side farther from the wall surface forming material 3 has openings 10a at both ends thereof. A single cloth piece 10b on the side closer to the wall surface forming material 3 and the wall surface forming material 3 are joined together by a fastener 39, and the bag also serves as a washing replacement cover which is composed of a series of bag-like bodies 24, 24. Are formed. Instead of the fastener 39, the attachment / detachment means may be an appropriate coupling means such as a button, a hook, or a magic tape.

In each of the embodiments, the two wall surface constituting materials 3 are closed together, as shown in FIG. In this case, it is preferable that the bag accommodates a thin piece of paper such as a thin piece of paper, but if a thick piece is accommodated, the appearance as shown in FIG. 2 cannot be maintained. A means for avoiding this is shown in FIG.
Shown in. In the figure, the wall surface component 3 is not a pure flat plate, but the inner surface of the bag is formed to be slightly concave, and as a result, a space 60 is formed between the two wall component parts 3. A desired space 60 is obtained by forming the curved surface of the wall surface component 3 into a desired shape. As a result, even if a slightly thick article such as a towel or a small radio is stored, the appearance is as shown in FIG.
As in (a), there is an advantage that the peripheral portion 5 can be closed.

Reference Example Throughout each of the examples, if the bag-shaped body is removed, the ability to store articles is reduced, resulting in a bag that is merely a "paper clip", and can be used to remove thin objects such as documents and towels. You can carry it between them. If such a limited application is tolerated, it can be used as an audio device.

[0025]

As described above, according to the present invention, when two bag wall surface constituent members are folded and closed, a thin bag is formed, and when opened, a plate-shaped audio device is formed, which can be carried in general. -Compared to earphones and headphones used for Dio equipment, it does not need to be worn on the body (ear),
He is free and does not feel uncomfortable.
In addition, the left and right sounds are well separated, so compared to a stereo system where two speakers are installed in the room, three-dimensional sound can be obtained, and even people who do not like wearing earphones or headphones can enjoy stereo broadcasting. You can listen to CDs and CDs with sufficient stereo sound. The voice has a feeling of liberation because the device is not attached to the body. At home, don't hesitate to study a family member, at hospital, don't hesitate to the bed next door, and the elderly don't hesitate to stay in the neighborhood.
Can be heard. It can also be used as a "wall-mounted" stereo or loudspeaker that breaks the conventional speaker concept. It can also be applied to medicine. When using a commercially available recording tape for psychotherapy, CD, etc., the device is not attached to the body (ear), so that a nervous person who dislikes wearing earphones or headphones does not feel pressure. ,
Also, the sound source is "fuzzy", so you don't have to worry about the existence of the sound source,
Psychotherapy can also be performed to enhance the effect on patients who are required to have a delicate atmosphere.
