[0037] In specific implementation, plastic and composite material generally have a high damping coefficient, and their physical internal structure has natural energy loss characteristics, which can effectively absorb and attenuate vibration. In this way, plastic has an advantage in attenuating and reducing unnecessary vibration when diffusing sound waves, and the high damping of plastic can effectively absorb these vibrations. The higher the damping coefficient, the better the material absorbs sound wave energy, and the less the amount of reflected sound. Using plastic or composite material as the main material can both absorb sound and diffuse, and has more appreciation value.

[0038] In specific implementation, rock wool as internal sound-absorbing material can further increase the sound-absorbing and damping effect of its fiber structure, especially for medium frequency (500-1khz) and high frequency (16k-20khz) sound waves.

[0039] In specific implementation, the rigidity and damping performance of plastic material can be adjusted according to the formula, which can better achieve the ideal sound effect. The plasticity of plastic material (due to the assistance of CAD / CAM and injection molding) enables the design to be adjusted according to specific acoustic requirements, and the internal rock wool provides excellent sound-absorbing capacity, which can effectively reduce medium and high frequency noise while maintaining low frequency diffusion effect.

[0040] In specific implementation, under the assistance of modern processing technology and CAD / CAM technology, a complex shape and an accurate acoustic diffusion structure can be designed, and the CAM technology is particularly high in processing efficiency of plastic, and the diffusion plate made of plastic material is rapidly formed through an injection molding machine, and has advantages in processing and manufacturing speed (especially for complex structures), flexibility and cost over wood.

[0041] In specific implementation, the plastic material can realize very complex shape design in the injection molding process, and almost has no shape limit, and a complex shape and an accurate acoustic diffusion structure can be designed.

[0042] In specific implementation, the sound-absorbing diffusion plate with a plastic / composite material-rock wool (hybrid design) structure can not only achieve diffusion effect, but also achieve a certain level of sound-absorbing performance, and can be used simultaneously, thereby reducing installation and manufacturing costs, and being stable in quality and performance.

[0043] In specific implementation, the structure (sound-absorbing diffusion plate) has better performance than a traditional wooden diffusion plate in terms of damping coefficient, especially in vibration attenuation and control in a medium-high frequency band, and the high damping, stable structure support and adjustable acoustic performance are indisputable.

[0044] In specific implementation, the DSS theory (Dynamic Surface System) is used, that is, non-parallel surfaces (irregular surfaces), non-parallel lines, irregular surface patterns and irregular depths are combined, and a complex geometric shape and artistic pattern are accurately calculated through CAD / CAM, and almost no shape limit is used to design a very complex three-dimensional structure, and the area can be increased to the maximum in the same range, so that better diffusion effect than the wooden diffusion plate can be achieved.
