Method, system and audio equipment for expanding sound field of audio equipment

Abstract

The present invention discloses a method and a system for expanding a sound field of an audio device, and an audio device. After direct sound signals in a current reverberation period and reverberation sound signals obtained through reverberation processing in the previous reverberation period are subjected to first mixing to obtain first mixing signals, the first mixing signals are subjected to reverberation processing to obtain the reverberation sound signals in the current reverberation period, the reverberation sound signals in the current reverberation period and the direct sound signalsin the next reverberation period are subjected to second mixing and then output, wherein, the purpose of the reverberation processing is to obtain the combination of the multi-level delay sound signals. Therefore, the direct sound signals are employed to perform multi-level delay and feedback and are output with the direct sound to simulate the sound filed scene that the direct sound is reflectedwhen the direct sound collides an object such as a wall and the reflected signals are mixed with the direct sound for reciprocating circulation so as to expand the sound field, obtain more natural space feeling and improve the user experience.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method, a system and an audio device for expanding the sound field of an audio device. Background technique [0002] With the development of the consumer electronics market, audio equipment has been greatly developed. People can use audio equipment to enjoy wonderful music on more and more occasions. At the same time, people's requirements for music from audio equipment are no longer just for sound quality, but also for sound field and sense of space. Therefore, more and more audio devices are positioned to provide users with immersive sound quality enjoyment, so that users can feel a wide sound field in a simple environment, achieving the effect similar to a concert hall. However, in the prior art, there is no relatively mature solution capable of expanding the sound field of the audio device. Contents of the invention [0003] The object of the present invention...
