The present invention relates to a chair capable of immersing acoustic vibration in three dimensions, and more specifically, to inserting a foam molding method when manufacturing a chair to increase the binding force between the cushion part and the vibration part, and to form a frame structure of a perforated network made of nonferrous metal. By securing excellent breathability by applying, it is possible to achieve more efficient and excellent vibration transmission effect in terms of manufacturability, to minimize the effects of magnetic interference on the vibration part and to improve the heat dissipation performance. will be.

In general, what is seen by the human eye is mainly 3D stereoscopic images, but when images shot using cameras or camcorders are viewed through the screens of TVs, monitors, and theaters, the stereoscopic feeling is greatly reduced because it is flat 2D. It is true that there is no.

Considering this point, in recent years, when watching a movie sitting in a chair of a large event hall, a three-dimensional cinema, etc. of a theater or an amusement park, a special effect device such as a transducer, etc. can be indirectly experienced. Many acoustic vibrating chairs having the same vibration part have been proposed.

However, most existing acoustic vibration-reducing chairs have many disadvantages in terms of manufacturability and performance.

First, after foaming the cushion part with a sponge or urethane during manufacture, a groove of a certain size is dug into the cushion part to secure the installation space of the vibrating part and the base plate, and then the vibrating part and the base plate are attached to the groove with an adhesive. In addition, it is disadvantageous in terms of manufacturability, such as difficult manufacturing and a large number of man-hours, because it requires installation and digging a separate wire seat for wire purchase.

Second, since the cushion portion and the vibrating portion are simply attached by the adhesive, a sense of unity between the cushion portion and the vibrating portion is reduced, and thus, the vibration of the vibrating portion may not be sufficiently transmitted to the cushion portion side, and thus, the effect thereof is lowered.

Third, in the case of the frame structure that closes the lower part of the cushion part in which the vibration part is installed, most of the steel plate is used. Therefore, the vibration part (transducer), which is a magnetic body, causes magnetic interference and degrades the performance of the vibration part. In addition, since the frame structure is a structure that blocks the entire vibrating portion around the vibrating, there is a problem that there is always a risk of overheating due to poor ventilation.

Accordingly, the present invention has been devised in view of such a point, and by integrating the cushion part and the vibrating part of the chair by insert foam molding, providing a sense of unity between the cushion part and the vibrating part and providing a sense of unity in terms of manufacturability. While more efficient and in particular, excellent vibration transmission effect can be expected, and by applying a frame structure made of non-ferrous metal in the form of perforated network, it provides a chair for acoustic vibration sensing to minimize magnetic interference with the vibration part and improve heat dissipation performance. Its purpose is to.

The present invention for achieving the above object is in the acoustic vibration sensing chair comprising a cushion unit, a vibration unit and a base plate, a frame structure, a cover, the vibration unit and the base plate is inserted in the foam molding of the cushion unit and the cushion unit and Characterized in that formed integrally.

In addition, the frame structure is characterized in that the edge portion of the cushion portion is inserted into a predetermined width. Inserts should be buried when foaming.

In addition, the vibrating portion is characterized in that the upper side is attached upside down.

In addition, the vibrating portion is characterized in that the upper surface has a cushioning member for receiving contact interference with the base plate.

In addition, the frame structure is characterized in that the non-ferrous metal of the perforated network form having a plurality of holes. In the case of steel structures, only the transducer part is cut.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a bottom perspective view showing the components of the chair for acoustic vibration perception according to the present invention.

As shown in FIG. 1, the chair for acoustic vibration sensation is largely composed of a backrest 19, a cushion 20, and a leg as a support means (not shown), and the cushion 20 corresponds to a cushion body. And a cushion portion 10, a vibration portion 11 for generating acoustic vibrations, a base plate 12 for supporting the same, a frame structure 13 corresponding to a cushion skeleton, a cover 14 as a finishing means, and the like. It is configured by.

In this case, the transducer is inserted in the backrest just like the seat, but there is no need for a frame structure because there is no need for a load-bearing structure like the seat.

The base plate 12 may also use an aluminum material in order to eliminate interference of magnetic force and improve heat generation performance.

In addition, as shown in Figure 2, the vibrator portion 11 can be applied to the usual transducers, etc., and fixed by assembling integrally with a fastening structure such as screws on the base plate 12 made of aluminum or the like. You can.

Reference numeral 18 in FIG. 2 represents a wire connected to the transducer.

As such, the vibrating unit 11 and the base plate 12 assembled in the assembly form are inserted in the foam molding of the cushion unit 10 and integrally molded with the cushion unit 10.

For example, the cushion part 10 is usually manufactured by foam molding in a molding mold using urethane, sponge, or the like. When the cushion part 10 is foam-molded, the vibration part 11 and the base plate are formed. By inserting (12) and foam-molding the cushion part 10, the cushion part 10, the vibration part 11, and the base plate 12 can be manufactured integrally.

Here, the method of foam-molding the cushion portion, the operation method of the vibration portion for vibration generation and the like can be adopted without particular limitation as long as it is a method commonly known in the art.

As the base plate 12 having the vibrator portion 11 is insert-foamed in the cushion portion 10, the cushion portion 10 between the base plate 12 and the firmer portion 10 is more rigid than the attachment state using a conventional adhesive. Binding strength can be secured, and in terms of manufacturing manpower, it is much more efficient in terms of manufacturability, as the vibration part and base plate seat can be cut down and then attached to the foam part in the foamed cushion part as before. This can be called.

In particular, when insert molding of the vibrating portion 11 and the base plate 12 as described above, the edge of the base plate 12 is inserted into the cushion portion 10 with a predetermined width, that is, the edge insertion of the base plate 12 The buried portion 17 is buried in the cushion portion 10, whereby the binding relationship between the vibrating portion 11 and the base plate 12 and the cushion portion 10 can be further strengthened, and thus the cushion portion 10 and the vibrating portion ( 11) The vibration transmission effect between the liver can be maximized, so that the realism and the three-dimensional effect can be enhanced to make the experience more inspiring.

On the other hand, when inserting the vibrating portion 11 and the base plate 12, the electric wire 18 connected to the vibrating portion 11 side is also inserted together, and the electric wire 18 at this time is usually able to withstand high temperatures during foaming. Double-coated wires may be applied, and it is preferable to wrap the foamed wire with a reinforcing sponge (not shown) on the interface with the cushion part (wall surface of the space where the vibration part and the base plate are installed).

This is to prevent the foam (cushion portion) from seeping into the space in which the vibration portion and the base plate belongs when a gap occurs during foaming.

By inserting the electric wire 18 together when inserting the vibrating part 11 and the base plate 12 in this way, the trouble of pulling out the cushion part for the electric wire embedding as in the past can be eliminated. The man-hours involved can also be reduced.

In addition, in the case of the vibrator portion 11 is installed on the cushion portion 10 together with the base plate 12 is taken upside down so that its upper surface is directed downward.

Normally, the vibrator portion 11 generates a considerable amount of heat during operation. The vibrator portion 11 does not face upwards, which is blocked by the cushion portion 10, but instead faces downwards with the end plate frame structure 13. The heat generated can be released more effectively.

In addition, the upper surface of the vibrating portion 11 is attached with a cushioning member 15 made of a sponge in the form of a circular ring, the buffer member 15 at this time is the upper surface of the vibrating portion and the frame structure 13 is in contact with each other By preventing the role, it is possible to prevent the damage of the vibrating portion 11, and to prevent the abnormal noise and the like that can be generated while the vibrating portion 11 hits the frame structure (13).

The frame structure 13 is a part serving as a kind of rigid body that supports the entire cushion portion, and has a rectangular frame 13a disposed along an edge and recessed downward in the frame 13a. The plate 13b is integrally welded or fastened with the mold.

In particular, the frame structure 13, that is, the plate 13b is made of a non-ferrous metal such as aluminum, stainless steel, etc., so that magnetic interference with the vibrator portion 11, which is a magnetic material, can be excluded, and the entire area of the plate 13b is prevented. A plurality of holes 16 are provided to more effectively discharge heat generated from the vibrator 11, and to ensure excellent breathability, such as allowing the wind to easily fall out when sitting on a chair. do.

3 is a cross-sectional view showing the structure of the assembly state of the acoustic vibration sensing chair according to the present invention.

As shown in FIG. 3, the vibrator portion 11 and the base plate 12 are integrally insert-molded in the cushion portion 10 through the insert portion 17, and a frame structure 13 is disposed below the insert portion 17. These are finally finished by the cover 14 to complete one chair, ie the cushion 20.

Since the vibration part 11 and the base plate 12 may have a sense of unity with the cushion part 10 by the insertion part 17, the vibration generated from the vibration part 11 may be more effectively cushioned by the cushion part 10. As the upper surface of the vibrator 11 faces downward and the hole 16 is provided in the frame structure 13, heat generated from the vibrator 11 may also be more effectively discharged to the outside. Can be. The heat dissipation is caused by the plane contact between the aluminum plane of the transducer and the insert.

As described above, the present invention applies the binding structure between the cushion part and the vibration part that strengthens the sense of unity by insert foam molding, and provides a chair for acoustic vibration sensing that adopts a frame structure made of a non-ferrous metal perforated network, thereby reducing manufacturing man-hours. It is possible to obtain the effect of improving the manufacturability, and in particular, according to the excellent vibration transmission effect between the cushioning portion and the vibrating portion, there is an effect that can experience a more sensational experience by increasing the realism and three-dimensional feeling, and ensure excellent ventilation, Since it can be improved, the effect of overheating can be completely excluded.
