Problems solved by technology

Coupled with the limited playback capability of the two speakers, the virtual rear surround sound effect is not obvious, and the sense of direction is still relatively poor
[0006] It can be seen that the existing technical solutions for enhancing the stereo effect of two-channel output cannot meet the needs of users.

Abstract

The invention provides a method for outputting audio signals and terminal equipment. The method is applied to the terminal equipment which is sequentially provided with a surrounding left speaker, a front left speaker, a middle speaker, a front right speaker and a surrounding right speaker, wherein the surrounding left speaker, the front left speaker, the middle speaker, the front right speaker and the surrounding right speaker are located on the same plane. The method comprises the following steps of: receiving the audio signals; respectively carrying out rear surrounding audio processing on surrounding left-channel audio signals and surrounding right-channel audio signals; and respectively outputting the processed surrounding left-channel audio signals and the processed surrounding right-channel audio signals to the surrounding left speaker and the surrounding right speaker. The sense of direction of the audio signals can be effectively improved, and the stereophonic effect is strengthened.

Description

technical field [0001] The invention relates to stereo sound processing technology, in particular to an audio signal output method and terminal equipment. Background technique [0002] The dual-channel output is usually used on the all-in-one computer. Since the dual-channel output will cause the sound to be transmitted from only two directions, the sense of direction and stereoscopic effect of the sound is poor, which affects the user experience. [0003] At present, the following two solutions are usually used to improve the stereo effect of the two-channel output: [0004] Option 1: Use dual-channel output and combine third-party sound processing software to process the sound, that is, use third-party audio processing software to output dual-channel virtual surround sound effects, but the perception range of virtual surround sound effects is relatively narrow , if the receiver moves to one side, the stereo effect will be worse; [0005] Option 2: Use binaural output and...
