Technical Field

The invention relates to shadow play performance equipment, in particular to a portable box-type shadow play deduction device.

Background

The shadow play deduction stage is a carrier of traditional shadow play performance, and is usually characterized by that the artist adopts two square tables, nine floor slabs and wooden rafters as supporting and enclosing six surfaces, the crossing position of the wooden rafters is tied by using rope, the front face of the wooden rafters is white cloth as screen, and other five surfaces of the wooden rafters are covered by five sheets of mat. The traditional shadow puppet stage has not changed for years, and in the early age with people having poor entertainment activities and economic conditions, the construction mode of the deductive stage is a model of local materials, economy and environmental protection and is widely spread among people. The economic culture of the present country is prosperous, and the culture confidence is provided to revive the excellent traditional culture for many years, which arouses the high attention of people. Nowadays, the traditional shadow play has rich and frequent activities such as entering communities, campuses, interactive research and the like. The shadow play deduction stage is required to have the integrated functions of convenient carrying, quick receiving, simultaneous sound and light lifting, movie people storage and the like. Obviously, the traditional shadow puppet stage building technology is not available, and the requirements of modern social and cultural activities can not be met. The defects are mainly reflected in the following points: (1) at present, no professional product capable of meeting the requirements exists in the market; (2) in activities such as entering communities and campuses by artist shadow shadows, stage construction is achieved by simple welding by artist, and support of a screen can only be met; (3) the performance site is messy due to the fact that deduction facilities do not integrate sound, light and electricity, wires need to be temporarily pulled according to the performance site through the wires, so that the performance is often limited by site conditions, and meanwhile, the wires scattered on the bottom surface have great potential safety hazards; (4) shadow play is mostly local opera, artists usually perform by adopting local dialects, and traditional stages do not have subtitle boards, so that most of people cannot understand the shadow play particularly when performing in modern urban crowds, and the transmission and experience of traditional culture are seriously influenced; (5) the traditional table does not adopt an integrated design, so that an artist needs to carry a plurality of articles such as a shadow play, a curtain, a support frame, light, a sound, a rope, a power line and the like in the process of performing outside, the carrying is very inconvenient, and the manpower, the time and the transportation cost are greatly increased.

Chinese patent CN 201910683732.8 discloses an automatic performance control method, device and storage medium for shadow puppet, the technical purpose is to perform adaptive control and adjustment on sound and light of shadow puppet stage, the technical result is guided by replacing artist control, although new viewing experience can be brought to the viewer, and the working intensity of the artist is reduced, the artistic shadow puppet only expresses through artist vocalization, and has a certain threshold for common audience to understand and accept, so that the traditional artistic form of shadow puppet cannot be spread more conveniently; meanwhile, the stage cannot be conveniently moved, carried and built, the technical cost is high, and the interactive platform of shadow play art and masses is not easy to build.
