Background

In a sound box system, a sound box generally consists of a high-pitch unit and a low-pitch unit, the two units are fixedly installed on a sound box panel, and due to the structural problem, the vibration systems of the high-pitch unit and the low-pitch unit are not on the same plane, so that distance difference, namely phase difference, is formed between the high-pitch unit and the low-pitch unit, and the Haas effect is generated. As a result, people hear the sound from the bass unit for the first time and then hear the sound from the treble unit. Although the measured bass and bass frequencies are balanced, the human ear is unbalanced due to the influence of the phase difference.
