Abstract
Official abstract text for this publication.
Disclosed herein is a waterproof sound-transmitting sheet, the thickness of which can easily be adjusted and which has a high sound transmitting efficiency and excellent waterproofness, and a method for producing same. The waterproof sound-transmitting sheet, which is attached to a sound hole of a case, includes: a support layer made of a film-shaped porous material and formed in the case; and a waterproofing layer formed on one side of the support layer in the shape of a porous nanoweb in which fine fiber strands are crosswisely layered and exposed to the outside of the case.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a waterproof sound-transmitting sheet, comprising the steps of: applying a spinning solution directly onto one surface of a support layer using electrospinning to form a waterproofing layer, wherein the spinning solution includes a polymer material and the support layer is made of a film-shaped porous material, and wherein the waterproofing layer is formed in the shape of a porous nanoweb in which fine fiber strands are crosswi…
