Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a cushion device that is installed on a part that supports the human body, such as a bed or chair.

(Prior art) So-called bass sounds with a frequency of 150 Hz or less are not only recognized by the sense of hearing, but also felt by the body as vibrations, and the overlapping of these sounds can be perceived as a realistic sound. can.

Various vibrators have been developed that convert low-frequency electrical signals into vibrations, and these vibrators are attached to the parts of cushioning devices, such as beds and chairs, that support the human body so that the user of the cushioning device can experience the vibrations.

Conventionally, such a cushion device has been constructed as follows. That is, a spring unit is formed by connecting a large number of coil springs in a matrix. A vibration transmission plate is superimposed on at least the upper surface of the upper and lower surfaces of the spring unit, and a vibrator is attached to this vibration transmission plate. The cushion body is constructed by covering a polymer of the spring unit and the vibration transmission plate with an exterior material.

In a cushion device having such a structure, the vibration transmission plate has a function of propagating vibrations generated by the vibrator to the entire surface of the spring unit, and is extremely important in improving the performance of the cushion device.

However, conventionally, the vibration transmission plate has simply been placed on the upper surface of the spring unit. Therefore, when the vibrator attached to the vibration transmission plate vibrates, only the vicinity of the vibrator of the vibration transmission plate is greatly deformed by the vibration, making it difficult for the vibration to propagate to the entire vibration transmission plate. occurs.

(Problem to be solved by the invention) In this way, the conventional cushion device simply placed a vibration transmission plate with a vibrator attached on the spring unit, so that the vibration of the vibrator was There were cases where it was difficult for the vibration to be propagated throughout the entire vibration transmission plate.

This invention was made based on the above circumstances, and its purpose is to provide a cushion device in which the vibrations of a vibrator attached to a vibration transmission plate are propagated well over the entire surface of the vibration transmission plate. It's about doing.

[Structure of the idea]

(Means and operations for solving the problem) In order to solve the above problem, this invention provides a spring unit formed by connecting a large number of coil springs in a matrix, and at least the upper and lower surfaces of this spring unit. A vibration transmission plate superimposed on the upper surface, a vibrator attached to the vibration transmission plate, a tensioning means for tensioning the vibration transmission plate to the spring unit with a predetermined tension, and the spring unit. It comprises a vibration transmission plate and an exterior body coated with a polymer. With this configuration, vibrations generated by the vibrator can be easily propagated throughout the vibration transmission plate, not only in the vicinity of the area where the vibrator is attached.

(Example) An example of this invention will be described below with reference to the drawings. FIG. 1 shows a mattress 1 as a cushioning device, which is equipped with a spring unit 2. As shown in FIG. This spring unit 2 has a large number of coil springs 3 arranged in a matrix, the upper and lower end surfaces of which are connected, for example, in the column direction by helical wires 4, and a frame line 4a is attached to the periphery of the upper and lower surfaces.

A cushion material 5 made of urethane foam or the like is superimposed on the upper and lower surfaces of the spring unit 2 via felts 5a, respectively, and a vibration transmission plate 6 is superposed on the cushion material 5 on the upper surface side.
This vibration transmission plate 6 is made of a semi-hard elastic material such as pressed palm or sisal, and has a fourth
A plurality of vibrators 7 are provided with one end surface thereof adhesively fixed in the arrangement state shown in the figure. Note that the cushion material 5 has a through hole 8 into which the vibrator 7 is inserted.
is drilled. The vibration transmitting plate 6 and the cushion material 5 on the lower surface side are covered with a mirror part 11 forming the exterior body 9, and the peripheral part of the spring unit 2 is covered with a gusset cloth 1 forming the exterior body 9.
Covered by 2. The mirror portion 11 is formed by interposing a sheet-like cushion material 15 between an outer material 13 and a lining material 14, and quilting these three materials together. The peripheral edge of the mirror portion 11 and the upper and lower ends of the gusset 12 are sewn together with tape edges 16.

Further, a plurality of flange cloths 17 (only one is shown) are provided at predetermined intervals on the peripheral edge of the upper surface of the vibration transmission plate 6.
One end is fixed with adhesive. The other ends of these flange cloths 17 are pulled with a predetermined tension so as to wrap around the periphery of the cushion material 5, and the spring unit 2
It is connected by a clip 18 to a coil spring 3 located around the periphery of the coil spring 3. Therefore, the vibration transmission plate 6 is stretched on the spring unit 2 with a predetermined tension by the flange cloth 17. Further, one end of the flange cloth 19 is sewn to the peripheral portion of the lining 14 of the mirror portion 11 on the lower surface side.
The other end of this flange cloth 19 is the flange cloth 17
Similarly, it is connected to the coil spring 3 of the spring unit 2 with a clip 18.

The vibrator 7 is constructed as shown in FIG. That is, the vibrator 7 has a dish-shaped housing case 22 with an open top. A flange 23 is formed at the open end of the storage case 22, and a peripheral portion of a lid 24 that closes the upper opening of the storage case 22 is bonded and fixed to the flange 23. A yoke 26 having an annular magnet 25 is elastically held within the housing case 22 by a damper 27. The yoke 26 includes a pole piece 29 having a bottom plate 28 formed on one end thereof;
It is composed of a ring-shaped yoke plate 31. Four protrusions 32 (only one shown) are protruded around the damper 27, and these protrusions 32 are fixedly attached to attachment portions 33 formed at the bottom of the storage case 22.

An opening 34 is formed in the bottom of the housing case 22, and a voice coil 35 is provided in this opening 34. The voice coil 35 includes a mounting plate 36 that closes the opening 34 and is attached to the outer surface of the bottom wall of the storage case 22, and a bobbin that stands upright on the inner surface of the mounting plate 36 and has a coil 36a wound around its outer periphery. It consists of 37. Above bobbin 37
is inserted into a space 38 formed by the outer peripheral surface of the pole piece 29 of the yoke 26 and the inner peripheral surfaces of the yoke plate 31 and the magnet 25. and,
When an electric signal that drives the speaker of the audio device is input to the coil 36a, the yoke 26 and the housing case 22 elastically move the damper 27 due to magnetic interference between the magnetic force generated in the coil 36 and the magnetic force of the magnet 25. Vibration is generated by relatively displacing the parts while deforming them.

The vibrator 7 having the above structure is provided with its lid body 24 adhered to the lower surface of the vibration transmission plate 6.

According to the Pine Torres 1 configured in this way,
When a user lies on the top surface and inputs a low-frequency electric signal to the vibrator 7, the vibrator 7 vibrates and the vibration is propagated by the vibration transmission plate 6. Vibration can be felt by the plate 6.

The vibration transmission plate 6 is stretched to the spring unit 2 with a predetermined tension by means of a flange cloth 17. Therefore, the vibration generated by the vibrator 7 does not cause the vibration transmission plate 6 to undergo large elastic deformation only in the vicinity of the vibrator 7, thereby damping the vibration.
Since the vibration is propagated to almost the entire vibration transmission plate 6, the user can feel the vibration of the vibrator 7 with the whole body. In other words, since the vibration transmission plate 6 is stretched with a predetermined tension, the vibrations generated by the vibrator 7 attached to the vibration transmission plate 6 are difficult to attenuate, so that good vibration is transmitted to the user's whole body. can be given.

Note that this invention is not limited to the above-mentioned example,
For example, the means for tensioning the vibration transmission plate on the spring unit is not limited to the flange cloth, but may be other means as long as the vibration transmission plate can be stretched on the spring unit with a predetermined tension. Furthermore, it goes without saying that the cushion device is not limited to a bed, but may also be a chair, a sofa, or the like.

[Effect of idea]

As described above, this invention is designed so that an elastic diaphragm made of a plate-shaped elastic material, which is provided on at least the upper surface of the upper and lower surfaces of the spring unit and to which a vibrator is attached, is stretched on the spring unit with a predetermined tension. I made it. Therefore, when the vibrator generates vibration, the vibration does not deform the vibration transmission plate greatly only in the vicinity of the vibrator, but the vibration is easily propagated throughout the body, so the user can feel the vibration throughout the whole body. , and can be subjected to relatively strong vibrations.
