sheet sheet Nanocomposite sheet for speaker diaphragm and manufacturing method of nanocomposite sheet for diaphragm of speaker

摘要

The present invention relates to a nanocomposite sheet for a speaker vibration plate and a manufacturing method of a nanocomposite sheet for a speaker vibration plate. The present invention is to resolve the aforementioned problem, in a nanocomposite sheet for a speaker vibration plate, it is possible to simplify a manufacturing process, reduce costs, and accordingly, make properties of a manufactured nanocomposite sheet for a speaker vibration plate much greater to provide a technology to improve quality of a speaker vibration plate. In addition, in a manufacturing process of a nanocellulose film, by uniformly distributing reinforcing agent, which is carbon-based material component, it is possible to significantly improve properties such as tensile strength, internal loss values, or elastic coefficient or more. In the case, uniform distribution of carbon-based material is important to express an effect as reinforcing agent, and by using a fluid collision apparatus, carbon-based properties can be uniformly distributed more effectively at nano level. Furthermore, since a sheet for a speaker vibration is provided as a sheet including at least one or more nanocellulose, which is natural polymer, and carbon-based material properties, due to nature of material, it is not only harmless to human body but also can be recycled to reduce manufacturing costs.
