Loudspeaker diaphragm, method of manufacturing same, and loudspeaker employing same

A method of manufacturing a loudspeaker diaphragm, the method comprising:

• forming a sealing layer on a first face of a woven fabric that is before or after the woven fabric is formed into a shape of a diaphragm, the sealing layer sealing a mesh opening surrounded by warp threads and weft threads of the woven fabric;
• when the sealing layer is formed before the woven fabric is formed into the shape of the diaphragm,
• (i) applying or spraying a first composite material onto a second face of the woven fabric so that the first composite material permeates to the sealing layer;
• subsequently forming the woven fabric into the shape of the diaphragm and drying the woven fabric,
• the first composite material being a mixture of a plurality of first short nanofibers and a first resin, the second face being on a reverse side of the woven fabric from the first face, or
• (ii) after forming the woven fabric with the sealing layer into the shape of the diaphragm, applying or spraying the first composite material onto the second face of the woven fabric so that the first composite material permeates to the sealing layer and drying the woven fabric, and
• when the woven fabric has been formed into the shape of the diaphragm,
• applying or spraying the first composite material onto the second face of the woven fabric so that the first composite material permeates to the sealing layer and drying the woven fabric.
