[0043] Through the special curved surface modeling of the annular anti-sound plate and the water ripple mechanism on the surface thereof, after the early sound waves are transmitted, the design modeling effectively changes the reflection direction of the sound waves, which is no longer the traditional single original path return, but forms a more divergent effect, which can minimize the influence on the later reflected sound, and can form better resonance with the later reflected sound in all directions, forming a more balanced acoustic effect.
