Functional Material for Acoustic Equipment

Abstract

[Object] To provide the functional material for acoustic equipment of this invention made by molding and curing the resin composition consisting of a thermosetting resin and a filler shows superior sound performance to the conventional material. [Means to Resolve] The functional material for acoustic equipment made by molding the resin composition consisting of the thermosetting resin and the filler, where a specific gravity of the molded material is between 1.5 and 5.0, the porosity of the molded materials is between 2% and 20%, and the average pore size of the materials is between 0.1 μm and 3.0 μm. The resin composition has 5-25 weight % of the thermosetting resin relative to the entire amount of the resin compositions and the filler of the resin composition partially includes 10-35 weight % of the porous filler (preferably having micro porous structure) relative to the entire resin composition.

         1 . Functional material for acoustic equipment, which is a molded resin composition consisting of a thermosetting resin and a filler, wherein
 a specific gravity of the molded material is between 1.5 and 5.0,   a porosity of the molded material is between 2% and 20%, and   an average pore size of the material is between 0.1 μm and 3.0 μm.   
     
     
         2 . The functional material for acoustic equipment according to  claim 1 , wherein
 said resin composition has 5-25 weight % of the thermosetting resin relative to the entire amount of the resin composition.   
     
     
         3 . The functional material for acoustic equipment according to  claim 1 , wherein
 said filler of the resin composition partially includes 10-35 weight % of a porous filler relative to the entire resin composition.   
     
     
         4 . The functional material for acoustic equipment according to  claim 3 , wherein
 said porous filler has a micro porous structure.   
     
     
         5 . The functional material for acoustic equipment according to  claim 4 , wherein
 said porous filler with the micro porous structure is one or more selected from a group of zeolite, active carbon, porous silica, and porous alumina.
