Composition of materials

Material composition:Framework: Commonly used materials can be divided into three categories (paper, aluminum, chemical fiber)         Apply SV glue and LOCK glue to the surface of the material through the coating process. SV glue has a long-term temperature resistance of 180 degrees, and LOCK glue has a long-term temperature resistance of 120 degrees. Choose different glue materials based on the power of the speaker.SV glue has high temperature resistance and low primary viscosity.LOCK glue has high viscosity and low temperature resistance.Requirements for the skeleton: Light, hard, and high temperature resistance are the best.Reinforcement paper: coating process on the surface of materials, long-term temperature resistance of 120 degrees, high primary viscosity. It mainly serves as a medium for fixing the outlet wire, increasing the strength of the skeleton, and bonding with the elastic wave in the horn.
