Left and right channel top bluetooth speakers reverse will have two directions:
(1) The left and right top bluetooth speakers to the sound of the sound field in the opposite direction of vibration, the sound energy between each other in the sound field against the cutting, the phenomenon of short circuit, resulting in the volume of the playback sound can not reach the desired volume , Sound intensity variation, bass turbidity and so on.
(2) Since the left and right channel sound has a phase difference of 180 °, the sound image localization in reproducing the stereophonic music is largely accomplished by the phase difference between the left and right channels. Stereo theory tells people that when there is a 180 ° phase difference between the left and right channels, the listener perceives the stereo image as going to the outside of the two top bluetooth speakers, where the source is erratic, vague and confusing, stereo-specific Sense of space and sense of sound surrounded by a sense of destruction. In this case,Audio system in the installation of the connection is very prone to reverse phase, if there is reverse phase, as long as the top bluetooth speakers line can be reversed. In this case,It is a simple and easy way to check whether the top bluetooth speakers is inverting with the audition method. This method can be used when there is no dedicated phase measurement device (such as phase meter).
At present, the market has a dedicated CD audition disk, recording the left and right channels in phase and reverse phase of the two voices, playing a sound before the top bluetooth speakers will tell the player is about to play the sound is left and right in-phase or inverting. If the in-phase sound is better than the reverse, then the left and right channel top bluetooth speakers are in phase; the contrary, then the top bluetooth speakers reversed. There is no dedicated audition disc, with better quality of the music program source can also be compared through the sound to check the left and right channel top bluetooth speakers if there is reverse phase. Listening carefully observe the two connections in the stereo sound, intensity, dynamics and bass and other aspects of change, can be discriminated, the superior for the same phase, the inferior to reverse phase.
True phase
Real phase refers to the sound system or sound signal input and output phase relationship between. Reversal of the real phase will be slightly less than the middle tone, poor sound brightness. The normal phase state should meet two conditions: First, the deliverytop microphone pickup, the microphone diaphragm vibration direction must be consistent with the vibration direction of the diaphragm diaphragm; the second is the use of audio equipment (such as deck, CD, etc.) to the system When an audio signal is input, the input signal must be the same as the phase of the output signal (ie polarity). If you can not reach the above two conditions, is the real phase inversion. The way to check whether the true phase is inverted is simple, but it must be done after the phase correction of the left and right channel top bluetooth speakers or in phase. The relationship between the microphone and the phoneme can be used as follows: to send sound to the microphone, the left and right channels of the two top bluetooth speakers of the cable or microphone 2, 3 end, without changing the power amplifier volume, Before and after the exchange of sound, the microphone volume is relatively small reverse connection, the larger is the same phase connection. If you use the sound source to play music sound, you can carefully taste the music in the bass components, without changing the power amplifier volume under the premise of comparing the two connections of the sound, the midrange slightly better for the real phase in phase.
