Embodiment Construction

[0042] Combine below Figure 1 to Figure 13 , the present invention is further described:

[0043] Such asfigure 1 As shown, a digital cinema sound reproduction system includes surround screen speaker array 2, subwoofer 3, surround speakers 4, 5, 6, power amplifier, digital cinema processor, main channel DSP processor, surround channel DSP Processor and software control platform, etc. The ring-screen speaker array 2 is composed of multiple speaker sub-arrays 2, and the multiple speaker sub-arrays 2 are closely and evenly distributed around the screen made of non-sound-transmitting materials.

[0044] The sound reproduction system processor analyzes the movie sound signal, so that the sound signal enters the main channel DSP processor and the surround channel DSP processor through different channels. Control the overall sound field environment through the software control platform, compensate the original movie theater sound field, and generate a variety of different virtual ...

Abstract

A digital cinema sound reproduction system and a control method therefor. The digital cinema sound reproduction system comprises a sound reproduction system processor, a main sound channel DSP processor, a surrounding sound channel DSP processor, a software control platform, a power amplifier, a screen-surrounding loudspeaker array (2), an ultra-low frequency loudspeaker (3), and surrounding loudspeaker groups (4, 5, 6). The digital cinema sound reproduction system is characterized in that: the sound reproduction system processor parses and processes a movie sound signal, and the software control platform enables the sound signal to enter the main sound channel DSP processor and the surrounding sound channel DSP processor by means of different sound channels. The software control platform controls an overall sound field environment, so that different frequency bands or different signals form different directivity; a virtual sound source can also be generated and an optimal sound receiving point is removed; multiple kinds of different virtual sound field environments are generated so as to adapt to different movie picture projection environments.

Description

technical field [0001] The invention relates to a digital cinema sound reproduction system, in particular to a digital cinema sound reproduction system suitable for non-sound-transmitting material screens and a control method thereof. Background technique [0002] The current digital cinema sound reproduction system is composed of horn-type main sound reinforcement speaker system, subwoofer, surround speaker, professional power amplifier, digital cinema processor and digital audio processor. The matching video projection system is professional digital high-resolution Projector and special sound-permeable screen. The main projector manufacturers are monopolized by foreign technology, and the resolution is generally 2K (2048x1080). The development trend of projectors is that the resolution is gradually increased from 2K to 4K (4096x2160). The horn-type main sound reinforcement speaker system + subwoofer is generally placed behind the sound-transmitting curtain to work. [00...
