Description

Hi-Fi mode control method and device Technical Field The invention relates to the technical field of sound equipment, in particular to a Hi-Fi mode control method and device. Background With the development of home entertainment equipment, soundbar (whispering gallery) gradually becomes an important component of a home theater system by virtue of its small size, convenient installation, wide sound field coverage, etc. The existing Soundbar mostly adopts multi-channel structures such as 5.1, 7.1.4, 9.1.4 and the like so as to meet the requirements of immersive sound effects of movies, games and the like. Meanwhile, manufacturers often add multiple EQ (equalization) modes to Soundbar, such as movie mode, music mode, vocal mode, sports mode, game mode, night mode, etc., to accommodate different usage scenarios. However, in the prior art, the above modes are all implemented based on multi-channel collaborative sounding, and regardless of the sound effect mode, all or most channels of the system participate in sound output, and the sound effect style is changed by means of gain adjustment, sound field expansion algorithm, and the like in different frequency bands. While this approach may enhance the multi-channel immersion, it is not suitable for the high fidelity playing requirements of clean music. For example, in a music appreciation or quiet environment, users often want to obtain a listening experience like a traditional two-channel Hi-Fi sound system, i.e. a concentrated, clean, accurate stereo image localization. However, since the multi-channel Soundbar naturally includes a plurality of sounding units in different directions, these additional channels interfere with stereo playback when playing music, so that sound image localization is not centralized enough, sound purity is reduced, and it is difficult to simulate the hearing of the conventional two-channel sound. The prior art also lacks a solution that can be in the same Soundbar while taking into account both the "home theater multichannel immersion experience" and the "ambisonics music experience". Therefore, a new channel control method is urgently needed, and unnecessary channels can be closed when needed, so that the output of Soundbar is more similar to the traditional two-channel Hi-Fi system, and the purity and the sense of reality of music experience are improved. Based on the method, the invention provides a Hi-Fi mode control method and device for Soundbar, and the high-fidelity stereophonic playing in multichannel equipment is realized by selectively starting and stopping each channel and performing differential signal processing, so that the technical contradiction that the cinema and the Hi-Fi cannot be considered in the prior art is solved. Disclosure of Invention The invention aims to provide a Hi-Fi mode control method, which aims to solve the technical problem that the prior art cannot consider cinema and Hi-Fi.
