Method for realizing multichannel panoramic sound playback by using earphone

Abstract

The invention relates to a method for realizing multichannel panoramic sound playback by using an earphone, which comprises the following steps of: arranging a plurality of sound production units in an earphone shell, and arranging more than six sound production units in each shell to form a surround sound and panoramic sound system; the six sound production units are two top sound production units, one front sound production unit, one side sound production unit, one rear sound production unit and one subwoofer sound production unit in sequence, and the rear sound production unit is arranged in the center of the rear part of the shell; an audio output signal is processed through the audio decoding circuit, the DSP sound effect processing circuit and the multi-channel audio amplification circuit and is played through the sound production unit. According to the invention, the sound production units are deployed according to the surround sound and panoramic sound modes, and 5.1 and 7.1 surround sound formats are downwards compatible, so that the multi-channel surround sound and panoramic sound can be replayed by using the earphone.

Description

technical field [0001] The present invention relates to the technical field of earphones, in particular to a method for realizing multi-channel panoramic sound playback by using earphones. Background technique [0002] Stereo refers to sound with a three-dimensional effect. The sounds produced in nature are stereo, but if these stereos are recorded, amplified, etc. and then reproduced, all the sounds are released from one speaker, and the reproduced sound (compared to the original sound source) is not stereo. . This is because various sounds are emitted from the same speaker, and the original sense of space (especially the sense of spatial distribution of the sound group) also disappears. If the entire system from recording to playback can restore the original sense of space to a certain extent, then this playback sound with spatial distribution characteristics such as a certain degree of azimuth layering is called stereo. [0003] Generally, the so-called stereo refers t...

Problems solved by technology

[0007] However, Dolby surround sound and panoramic sound appear more in movie theaters than in home theaters, and are basically not realized in portable listening environments.

[0008] However, the existing solution mainly solves the need to meet a series of conditions such as venues and equipment to realize the retransmission of the surround sound multi-channel sound field. This playback solution has a large space, high cost, and many equipments, and it is difficult to promote.
