Method and device for improving stereo sound effect

Abstract

A method for improving the sense of stereo, which includes a left channel and a right channel; the left channel input signal is compared with the right channel input signal after phase inversion by 180° to obtain a left difference signal, and the left difference signal is phase inverted by 180° ° After being superimposed with the right channel input signal, it is used as the right channel output signal; the difference between the right channel input signal and the left channel input signal after 180° phase inversion is compared to obtain the right difference signal, and the right difference signal is inverted 180° After being superimposed with the input signal of the left channel, it becomes the output signal of the left channel. The present invention extracts the difference signal of one of the channels in stereo, and the difference signal is inverted by 180° and superimposed with the input signal of the other channel as the output signal of the other channel. The sound of one of the channels can be heard by the ear, so as to improve the stereo sense of the speaker product; at the same time, adding appropriate reverberation sound to the left and right channels can enhance the sense of space of the sound.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a method and a device for improving the sense of stereo. Background technique [0002] With the development of science and technology, more and more technological products have entered people's lives and profoundly affected our way of life. Such as mobile phones, computers, speakers and other digital products. In particular, with the development of audio-visual technology, portable speaker products with small size, powerful functions and low power consumption are becoming more and more popular, especially favored by young people, and gradually become a consumer fashion. Moreover, the functionality of portable speaker products is gradually enhanced, and the volume is getting smaller and smaller. Although the sound quality is limited by the volume, the sound quality of today's portable speakers is better than before. In addition, as flat-panel TVs have become popular, and due...

Problems solved by technology

In addition, as flat-panel TVs have become popular, and due to the rapid development of technology, the thickness of TVs is getting thinner and thinner. Although it brings people high-definition and ultra-thin visual enjoyment, it is getting thinner and thinner in terms of sound quality. The sound quality of CRT TVs is full and vigorous, and consumers cannot be satisfied with the enjoyment of hearing. Therefore, SOUNDBAR speakers specially designed to make up for the lack of sound quality of flat-panel TVs are also loved by manufacturers and consumers.

[0003] Although the product performance of portable speakers and SOUNDBAR speakers is getting better and better, but on some portable speakers and SOUNDBAR speakers, the stereo sense is not good due to the short distance between the speakers.
