Speaker phase judgment

Speaker phase refers to the speakers in series, parallel use of the positive and negative connection: when using two or more speakers, try to ensure the consistency of audio current flows through the speakers, so that we can keep the vibration direction of loudspeaker paper cone-to, so that vibration of the air energy is offset and not sound-reducing effect. To can do this request requires in-line using a positive speaker connect the anode of the other speakers in turn; when used in parallel, each speaker connected to the anode and cathode, anode and cathode are connected, which is reached in phase with the requirements.
