4D Cinema

As a professional high-tech company in the 4D cinema industry, Yaisu has developed the internationally leading crank structure electric dynamic seat for many years, and its stability and durability have been highly praised by customers. Users include theme parks and large enterprises such as Vanke Museum of Shanghai World Expo, Shanghai Nature Museum, Shijingshan Amusement Park and Tianshili group. 

The projects are all over China's provinces and cities.

4D cinema is developed from the traditional 3D cinema. Compared with other types of cinemas, 4D cinema has the characteristics and advantages of prominent theme, high scientific and technological content, realistic effect, strong picture impact and so on. People not only introduce special effects such as vibration, falling, blowing, spraying water, scratching and leg sweeping into 3D cinemas, but also carefully design effects such as smoke, rain, photoelectric, bubbles and smell according to the scene of the film, forming a unique experience. This is the very popular 4D cinema today. Because the audience can get all-round feelings such as vision, hearing, touch and smell when watching 4D films.

Facial spray: it can spray a small amount of water on the audience's face to simulate sneezing, water pipe rupture and other situations;

Facial jet: compressed air is directly blown to the audience's face, simulating the feeling of explosion impact and bullet flying in the picture; The air jet effect is completed by the air nozzle of each seat and acts on the head and neck of the audience;

Movement: roll up and down, left and right, back and forth to simulate pitching, rolling, lifting and other movements. It is often used to simulate the rolling, flying and running to the left and right in the film, hanging and falling forward, looking up, taking off and looking up.

Vibration: the equipment is built into the seat cushion, which can be pushed up and down when acting to realize the vibration frequency of 12Hz and make the audience feel the "vibration" from top to bottom;

Leg sweeping: a small elastic air hose is hung under each seat. When mice, snakes, insects and other animals appear in the film, the hose will beat the audience's lower legs, which can simulate the feeling of animals under the audience's legs;

Push back: a new type of equipment is built into the seat back, which can push forward when acting, realize the vibration frequency of 5Hz, and make the audience feel the sudden "vibration" on the back, with a strong sense of "push back" and "electric shock".

Adopt high-quality sound effect material - multi-channel surround sound system as the sound system of the cinema. Provide 2.1 to 6.1 or even 7.1 channel systems to enhance ambient sound effects. (for example, add sound channels over the cinema to simulate aircraft flight, thunder, etc.) the multi-channel surround sound system of 4D cinema fully considers the characteristics that cylindrical 4D cinema can make 3D objects move around, which can accurately locate moving objects, make the sound of 4D film and television three-dimensional, and form a real three-dimensional sense of space.

After all the above elements are available, how can they play their role organically and orderly? This requires a computer control system specially designed for different film contents to function. The core of the control system is the control software. The program engineer sets commands at an accurate time point according to the film contents to control the switches of the projection system, special effect seats, special effect equipment and sound system, so as to make the whole 4D cinema system an organic whole, Provide the audience with all-round sensory experience.

The balanced point sound source speaker technology of 4D cinema uses a separate audio channel to play sound, so that the audience can hear the sound source of each sound. (the traditional 5.1 distributed sound system plays sound through multiple speakers, which will make the audience unable to identify the sound source.) each 4D theater is acoustically processed, which can accurately and truly present the sound image with the maximum dynamic range. Therefore, the sound played in each 4D projection hall is extremely clear. The audience can not only hear the sound of a needle falling to the ground, but also hear the position of the needle falling. The soundtrack of each 4D film has been specially made to adapt to the unique sound system of 4D.

4D cinema strives to create a "sense of immersion", that is, the 4D animation is interspersed with live performances and real scenes. When you jump to the 4D effect, the cinema will remind you. Zhou Yun, manager of a traditional cinema, told reporters that the 4D films in Shenyang now emphasize entertainment and pay more attention to the display of special effects technology, while people who go to traditional cinemas pursue storylines, characterization and other aspects. Therefore, these are two different audience groups, and there is no problem of competition and interaction. Moreover, Mr. Fu said that to some extent, 4D cinema may also consider opening around ordinary cinemas to take advantage of its passenger flow.
