AI Technical Summary

Technical Problem

Existing LED acoustically transparent screens lack safety protection measures after the installation of the sound channel speaker system, which can easily lead to sound wave obstruction and harmonic distortion, and can also cause damage to components and the risk of unauthorized recording.

Method used

The system employs a sound-transparent display module and a safety link protection unit. The sound-transparent display module is spliced ​​together with the support beam of the mounting frame, and the drive line area is hidden behind the support beam. The safety link protection unit triggers the projection system to pause when it is forcibly opened, forming a protection system in combination with the physical locking structure.

Benefits of technology

It effectively increases the sound transmission area, reduces sound attenuation and harmonic distortion, prevents piracy, and ensures the safety of the projection system.

Abstract

The invention relates to the technical field of LED screens, and discloses an LED sound transmission screen for digital film projection, a sound transmission assembly and a film screen, and the sound transmission screen comprises a plurality of sound transmission display modules, a mounting frame and a safety link protection unit; each sound transmission display module comprises a sound transmission display area and a driving circuit area, the multiple sound transmission display modules are spliced on the front side of the mounting frame through supporting beams of the mounting frame, the sound transmission display areas correspond to the areas without the supporting beams, and the driving circuit areas correspond to the supporting beam areas; when the safety link protection link connection enables the safety link protection shell to be locked, the supporting beams of the mounting frame are packaged on the rear sides of the sound transmission display modules; and when the safety link protection link is disconnected and the safety link protection shell is opened, the safety link protection link is triggered to transmit a protection signal to the LED projection system, so that the LED projection system stops projection. According to the sound transmission screen provided by the invention, the effective sound transmission area can be improved, and the digital film projection protection level is improved.
