Mobile sound source 3D audio system based on sliding track

Abstract

The invention provides a mobile sound source 3D audio system based on a sliding track, which comprises a 3D audio processing system and an automatic sliding sound playing system, and is characterized in that the 3D audio processing system comprises a data input end, a data output end and a central processing unit, and the moving distance obtained after processing of the central processing unit is sent to a pulley control device; the sliding sound playing system comprises a plurality of sound devices and sound card devices which are arranged in a layered mode, all or part of the layers are provided with rails, and the other layers are provided with sound devices at fixed positions; one or more sound boxes with pulleys are arranged on each layer of track, a pulley control device is arranged, the pulley control device drives the sound boxes to slide on the track through the pulleys after receiving the moving distance of each sound box, and the distance between the sound boxes is changed; and each sound box is connected with different sound channels of the sound card equipment. According to the invention, the optimal position point of sound equipment movement can be determined, and better 3D audio experience can be provided with fewer sound equipment.

Description

technical field [0001] The invention belongs to the technical field of 3D audio, and in particular relates to a mobile sound source 3D audio system based on a sliding track. Background technique [0002] At the end of 2009, the 3D movie "Avatar" topped the box office charts in more than 30 countries around the world. By the beginning of September 2010, the cumulative global box office had exceeded 2.7 billion US dollars. The reason why it can achieve such brilliant box office results is that the film uses 3D special effects production technology, which brings a huge shocking effect to people's senses. The gorgeous pictures and realistic sound effects shown in "Avatar" not only shocked the audience, but also made the industry assert that "movies have entered the 3D era". Not only that, it will also give birth to more technologies and standards related to film and television, recording, and playback. At the International Consumer Electronics Show held in recent years, 3D vid...
