11.2 channel, 3d4k HD, 3-way speaker, metal low reflection screen and intelligent lighting effect, etc. are only the effective combination of various hardware. In addition, today I would like to share with you how to use different materials to achieve good sound effect. Make sound insulation, sound absorption, resonance sound, and sound effective reflection, to achieve non conflict. I must grasp the following three points: first, double-layer fully sealed sound insulation cotton, so that the sound does not leak; Secondly, the structure and the main body of decoration generate a vacuum anti vibration treatment layer, which will not have resonance effect; Third, the surface 50:50 ratio of reflection and sound absorption, so that the sound will not feel too dry and empty.
