Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pillow for one person to listen to music, radio broadcasts, etc., in detail, without causing noise damage to those around them.
Moreover, the present invention relates to a pillow which does not cause any obstacle when changing the position or direction of the head and can protect the head flexibly.

[Prior Art] As a device for listening to music etc. by one person at midnight, early morning, etc. without causing noise damage to others, the applicant of the present invention has previously put it into practice.
No. 1-199275 was proposed. FIG. 5 is a sectional explanatory view showing an example of the pillow 1 according to the above proposal. That is, containers 2 and 2 are arranged on the left and right of the pillow 1, and as shown in an enlarged view in FIG. 6, the sound reproduction unit 12 (for example, a driver unit of a speaker or a headphone) has its front side (the upper surface of the pillow 1). It is attached to the inner surface side of the dustproof cover 11 arranged on the side 1A). The dust cover 11 has a front side sound wave passage opening 11a in the sound reproduction unit 12, and
A rear side sound wave passage opening 11b is formed. An acoustic reflector 30 is attached above the dustproof cover 11,
The front side sound wave is guided so as to directly reach the ear M of the user M, and in the area away from the user M, the front side sound wave and the back side sound wave cancel each other due to mutual interference to generate a large sound. Is configured so that it does not diffuse around.

[Problems to be Solved by the Invention] By using the pillow having the above-described configuration, it is possible to supply the pillow user with high sound quality front side sound waves at an appropriate volume, and to prevent noise damage to people around. However, when the pillow user M falls asleep as it is, or when it is used only as a sleeping pillow or a headrest without listening to music, the user M shifts the position of the head by turning over (the broken line M in FIG. 5). ₁ )), the ear Y comes into contact with the dust-proof cover 11 only by separating one cloth pillow cover 24,
There is a risk that the user M will be given pain or discomfort. In particular, since the dustproof cover 11 is formed of a hard synthetic resin material, metal, wood, or the like for the purpose of supporting and fixing the sound reproducing unit 12, the above problem cannot be ignored. The acoustic reflector 30 is made of a soft synthetic resin such as foamed polyurethane or a soft material such as soft rubber, and has a detachable structure. Therefore, the presence of the acoustic reflector 30 causes great discomfort to the user M. There is no such thing.

By providing the container 2 in this way, it is difficult to protect the head flexibly, which is the basic function of the pillow, which is a big problem.

Therefore, the present inventor keeps the function of providing high-quality sound to the listener without diffusing noise around the pillow, and does not cause discomfort or pain even if the user changes the position of the head. The present invention has been completed by repeated efforts for the purpose of providing.

[Means for Solving the Problems] In the present invention which has achieved the above object, the container is disposed inside the pillow, and the front surface of the sound reproducing unit is disposed between the sound wave passage opening surface of the container and the upper surface of the pillow. At least an elastic partition wall for partitioning the side sound wave passage space and the back side sound wave passage space is provided, and an acoustic reflector is fixedly or detachably disposed above the elastic partition wall. It is a thing.

[Operation and Embodiment] FIG. 1 is a sectional explanatory view showing a typical embodiment of the present invention, FIG. 2 is a partially enlarged sectional view of FIG. 1, and FIG. 3 is an exploded explanatory view of FIG. is there. Similar to the conventional example shown in FIGS. 5 and 6, the sound reproducing unit 12 is housed in the container 10, and the sound reproducing unit 12 is attached to the dustproof cover 11 on the front side. In addition, the dust cover 11 includes a sound reproduction unit 12
A passage opening 11a through which the front side sound wave is transmitted and a passage opening 11b through which the back side sound wave is transmitted. The container 10 configured as described above is embedded in the inner depth of the pillow with a depth Dp. On the other hand, an elastic cylindrical body 20A formed of an elastic body is provided outside the container 10. The elastic tubular body 20A is required to exert an appropriate soft elasticity when the head is placed directly on the elastic tubular body 20A, and the material is not limited in the present invention, but urethane foam, foam rubber or the like is preferable. It is preferable to use a soft synthetic resin foam or compressed cotton (commonly called solid cotton). In the above example, the elastic tubular body 20
Although the bottom wall 20C is integrally formed on the lower side of A, the present invention is not limited to this embodiment, and the bottom wall 20C is not limited thereto.
However, the elastic cylindrical body 20A may be formed only by the hollow cylindrical elastic cylindrical body 20A.
The cross-sectional shape of A is not limited to a circle, but may be a polygonal shape. On the other hand, on the upper side of the dustproof cover 11, a cylindrical elastic partition wall 20B is attached so as to surround the entire front side sound wave passage opening 11a, and the upper space of the dustproof cover 11 is fronted by the elastic partition wall 20B. The side sound wave passage space 22 and the back side sound wave passage space 21 are divided. Further, above the elastic partition wall 20B, an acoustic reflection plate 30 having a shape obtained by obliquely cutting a cylindrical body formed of a soft material is detachably attached to the upper surface of the pillow cover 24. The acoustic reflector 30 is made of a soft rubber or a soft synthetic resin material and has a removable structure with respect to the pillow cover 24. A removable structure A using Velcro (trademark) or magnetic force may be used. preferable. In addition, the passage spaces 21, 22
If a large opening is still formed in the upper part of the pillow cover 24, there is a risk that the ear Y may completely fit into these openings from above the pillow cover 24. Therefore, in order to prevent this, the elastic tubular body 20A is prevented. A soft net material 23 may be arranged between the upper surface of the elastic partition wall 20B and the pillow cover 24.

In the pillow 1 configured as described above, the back side sound wave of the sound reproduction unit 12 passes through the sound wave passage space 21 and is extracted to the atmosphere side, so that a smooth cone vibration can be secured in the sound reproduction unit, and the sound reproduction unit 12 can be faithful. Can produce playback sound. Further, the sound wave on the front side generated by the sound reproduction unit 12 is a sound wave passage opening 11a and a passage space 22.
Also, the ear Y of the user M can be directly reached through the inside of the reflection plate 30 and the user can be provided with a good reproduction sound. Further, the sound waves on the back side of the sound reproduction unit 12 are emitted to the periphery of the pillow through the sound passage opening 11b and the passage space 21 and diffused to the outside of the reflection plate 30, but as described above, they interfere with the sound waves on the front side. Since they cancel each other out, there is no noise to be scattered around.

Further, the present invention is further characterized in that even if the head of the user M moves to a position directly above the dust cover 11, the user's ear Y or head does not directly contact the dust cover 11, and the elasticity is elastic. Since the tubular body 20A and the elastic partition wall 20B are in contact with and supported by the tubular body 20A, the user does not feel any pain or discomfort. In addition, the effect is also exerted in protecting the sound reproducing unit in the container 10.

The burial depth Dp of the container 10 is preferably 20 mm or more from the upper surface 1A of the pillow, so that even when the ear Y enters the passage spaces 21 and 22, the ear Y
The dust and the like will not hit the dust cover 11 directly.
When the depth Dp exceeds 100 mm, the elastic cylindrical body 20A
Or the elastic partition wall 20B is crushed by the surrounding pillow filling (soba rag, panya, etc.) and buckles, and the sound wave passing spaces 21, 2
2 may be blocked. Therefore, it is desirable that the depth Dp is 20 to 100 mm. In order to prevent such inconvenience from occurring, another reinforcing wall member formed of an elastic member or the like may be provided in the sound wave passage spaces 21 and 22.

FIG. 4 (A) is a sectional explanatory view showing another embodiment of the present invention, and FIG. 4 (B) is a sectional view taken along the line BB of FIG. 4 (A). In this embodiment, the shape of the dust cover 11 in plan view is rectangular, and the elastic cylindrical body 20A 'provided between the pillow upper surface 1A and the upper surface of the dust cover 11 is an elastic cylindrical body having a rectangular cross section without a bottom wall. An elastic partition wall 20B 'that vertically divides a space formed therein is integrally formed to form a front side sound wave passage space 22a and a back side sound wave passage space 21a. The acoustic reflector 30 used in this embodiment has a horizontally long shape.

The pillow of the present invention may be applied not only to a pillow used as a bedding but also to a pillow used in a headrest portion 51 of a seat 50 as shown in FIG. 4 (C). In this embodiment, the headrest body, the elastic tubular body and the elastic partition wall are formed of an integral elastic material.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to supply music and the like with a sound quality and a volume satisfying the user without diffusing the noise to the surroundings, and the user's head and ears are hard. Since it does not hit the dust-proof cover directly, it does not cause pain or discomfort to the user, and does not impair the original function of the pillow.
