Cinema audio control device and system

Abstract

The invention provides an audio control device and system for a cinema, and relates to the technical field of the electrical equipment. The audio control device for the cinema comprises a central processing unit, audio equipment and a weight sensor arranged on each seat; various weight sensors are wirelessly connected with the central processing unit; the audio equipment is wirelessly connected with the central processing unit; each weight sensor is arranged on the surface of the seat; the audio equipment is arranged on the locations at different heights of a movie hall in a surrounding way; the weight sensor generates an attendance signal according to the weight value; the central processing unit computes the percent of the attendance signal in the total number of the seats, and then compares the relation of the percent and a preset threshold, controls the audio equipment at different heights to be respectively turned on according to the comparison result. Through the above setting, the attendance rate of the movie hall is computed, and the audio equipment with different powers at different locations is controlled to be respectively turned on by combining the attendance rate, andthe operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an audio control device and system for theaters. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various leisure activities are gradually enriched. In their spare time, people can plant flowers and raise fish, do sports, play video games, watch movies and so on. Among them, especially the rapid development of film-related technologies in recent years, people can enjoy various forms of movies under 3D, 4D, IMAX, water curtain, and dome scenes, thereby meeting people's appreciation needs. [0003] However, movies under the above-mentioned 3D, 4D, IMAX, water curtain, and dome scenes are usually played in movie theaters. The reason is that the realization of the above-mentioned special movie needs to be realized by means of many other devices (for example, water sprayer, shaking instrument,...

AI Technical Summary

Problems solved by technology

Although the construction of movie theaters has also increased in recent years, due to the relationship between movie release schedules and people's working hours, the attendance rate of movie theaters is very unstable

Sometimes the movie theaters are full during the release of a movie with a good reputation; sometimes the attendance rate is very low during the release of some movies

Regardless of the attendance rate, the same lighting, audio and other equipment will be used in the cinema hall of the cinema, which will not only cause a great waste of resources when the attendance rate is insufficient; audiovisual interference

[0004] To sum up, at present, there is no effective solution to the problem that cinemas cannot adjust the size of the sound system according to the actual occupancy rate.
