Description
Technical Field
[0001] The present invention relates to the technical field of earphones, and in particular to a high-stereo noise reduction Bluetooth earphone. Background Art
[0002] Stereo sound refers to sound with a three-dimensional sense. The sounds emitted by nature are stereo sound. However, if we record, amplify and process these stereo sounds and then play them back, all the sounds are played from one loudspeaker. This kind of playback sound (compared with the original sound source) is not three-dimensional. This is because all the sounds are emitted from the same loudspeaker, and the original sense of space (especially the sense of spatial distribution of the sound group) is also lost. This kind of playback sound is called mono sound. If the entire system from recording to playback can restore the original sense of space to a certain extent (it is impossible to restore it completely), then this kind of playback sound with a certain degree of spatial distribution characteristics such as sense of orientation and layering is called stereo sound in audio technology.
