(2) In addition, because the sensitivity of the horn causes the difference in time difference between the high bass and the low bass, it will also lead to phase distortion, so why the filters between the high bass and the low bass in the same frequency divider are often inconsistent.
(3) The signal will lose when it passes through any equipment, and it will lag when it passes through the filter in any circuit, which will also lead to its phase shift.
(4) When two speakers with correct phase sound at the same time, the audio-visual drift caused by pointing angle, placement position, distance from the audience and other factors can actually be classified as "phase", but the sound of the two boxes does not reach the human ear synchronously and the sound of a single speaker does not reach the human ear synchronously.
Extended data:
The influence of automobile audio phase error;
(1) causes the sound emitted by the left and right speakers to vibrate in opposite directions in the sound field, and the acoustic energy between them collides with each other in the sound field, resulting in the phenomenon of sound short circuit, which leads to the volume of the reproduced sound not reaching the proper volume, the sound intensity becoming worse and the bass is turbid.
(2) Because the sound of the left and right channels has a phase difference of180, the sound image positioning during stereo music playback largely depends on the phase difference of the left and right channels.
Stereo theory tells people that when there is a phase difference of180 between the left and right channels, the listener will feel that the stereo sound image runs outside the two speakers, and the position of the sound source is erratic and fuzzy, which destroys the unique effects of stereo presence, space and sound surround.
