Damper structure for speaker system

Abstract

A damper structure includes a plurality of first yarns; a plurality of second yarns transversely crossing and alternately overlapping the first yarns respectively in a knitted manner so as to define a plurality of overlapping areas, wherein the first and second yarns include at least one first or second yarn formed by a single yarn strand; and a fixture layer formed on and enclosing the overlapping areas in such a manner that each of the overlapping areas has a fixed configuration in cross-section.

What is claimed is: 
     
         1 . A damper structure comprising:
 a plurality of first yarns;   a plurality of second yarns transversely crossing and alternately overlapping said plurality of first yarns respectively in a knitted manner so as to define a plurality of overlapping areas, wherein said plurality of first and second yarns includes at least one first or second yarn formed by a single yarn strand; and   a fixture layer formed on and enclosing said overlapping areas in such a manner that each of said overlapping areas has a fixed configuration in cross-section.   
     
     
         2 . The damper structure according to  claim 1 , wherein said plurality of first yarns includes a portion consisting of at least one first yarn formed by a single yarn strand. 
     
     
         3 . The damper structure according to  claim 2 , wherein said plurality of first yarns further includes a remaining portion consisting of several pieces of said first yarns, each is formed by several twisted fiber strands. 
     
     
         4 . The damper structure according to  claim 1 , wherein said plurality of second yarns includes a portion consisting of at least one second yarn formed by a single yarn strand. 
     
     
         5 . The damper structure according to  claim 4 , wherein said plurality of second yarns further includes a remaining portion consisting of several pieces of said second yarns, each is formed by several twisted fiber strands. 
     
     
         6 . The damper structure according to  claim 1 , wherein said fixture layer further encloses entire surface areas of said plurality of first and second yarns in addition to said overlapping areas. 
     
     
         7 . The damper structure according to  claim 1 , wherein respective ones of said first and second yarns and said fixture layer are integrally formed with one another at a respective one of said overlapping areas once a heat treatment is conducted thereto. 
     
     
         8 . The damper structure according to  claim 1 , wherein each of said plurality of first and second yarns further includes one encapsulating sheath for sleeving over said single yarn strand. 
     
     
         9 . The damper structure according to  claim 8 , wherein said single yarn strand serves as a core while said encapsulating sheath serves as an external layer enclosing said core. 
     
     
         10 . The damper structure according to  claim 1 , wherein the damper structure is used as a damper substrate in a speaker system. 
     
     
         11 . The damper structure according to  claim 1 , wherein the damper structure is made from cloth fabric, such as cone paper. 
     
     
         12 . The damper structure according to  claim 1 , wherein the damper structure is used as a suspension plate for interconnecting a diaphragm to a spider frame of a speaker system.
