Description

[0001] INTAKE AND EXHAUST APPARATUS FOR REDUCING NOISE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake and exhaust device, and more particularly, to an intake and exhaust device for reducing noise that discharges air from inside of a housing part through a noise reduction part communicating with an air valve.

Generally, when viewed by a human eye, it is mainly three-dimensional stereoscopic image. However, when the image captured by a camera or a camcorder is viewed through a screen of a TV, a monitor, or a movie theater, to be.

Considering this fact, recently, when a movie is watched in a chair such as a large event hall or a stereoscopic movie theater of a theater or an amusement park, a special effect having a special effect device for indirectly experiencing various situations in a video Many chairs are being presented.

In the case of a movie theater, it can be largely divided into a special movie theater for the purpose of entertainment such as an opening movie showing general movies, a theme park, and an exhibition hall for educational and publicity purposes in a museum / public relations hall / company exhibition hall.

In addition, the movie fun or value of a movie which is shown in most movie theaters including a feature film and a documentary movie is determined by the completeness of the movie, that is, the scenario and the level of planning in which the idea of the artist is expressed, In most cases, by using only the visual and auditory sense of human senses, it is possible to convey the contents to audiences, so that the audience becomes the main character in the film and becomes more immersed in the film, participates in the film, Has been extremely limited.

Meanwhile, with the spread of digital media capable of bidirectional communication of signals and the revival of the movie industry in recent years, the possibility of a new type of movie market has been cautiously emerged.

By using stereoscopic equipment when filming a movie, three-dimensional stereoscopic movies, which have the same contents but enhanced the sense of reality, are released at the same time as two-dimensional images. There is also a specialized stereoscopic image viewer for the screening, There is also a movie theater that adopts a sensible chair that can experience a deeper sound experience by automatically vibrating in conjunction with the bass sound in the movie.

In addition, in the case of exhibitions and promotional videos broadcasted in museums and public relations offices, it is possible to construct dramas that appropriately utilize stereoscopic or computer-specific visual effects through scenarios, The number of cases in which a video system is configured to acquire knowledge naturally after video viewing is gradually increasing.

Accordingly, it reflects the psychology of modern people who desire a unique and diverse experience different from the conventional method which depends mainly on the visual sense, so that they can surprise audiences through simple physical stimulation of the human senses, that is, There has been a need for research on ways to make movies more interesting and to be immersed in movies by directing environmental effects similar to those of other media, and there have been various attempts to effectively transmit the messages having the video contents to the audience .

A typical example of the conventional special effect feeling chair considering these points is a drop type chair.

This drop-type chair is made by dropping the chair down as a whole. By giving a suitable point or chair instantly according to each scene in the movie, it is possible to create a situation similar to the one happening in the movie, And also provides an additional effect to experience reality.

However, in the case of a conventional drop-type chair, the air supplied to the hydraulic cylinder for positioning the chair upside and downside is constantly increased or decreased, resulting in a noise generated thereby and a dramatic effect of adding experience.
