Waterproof sound-transmitting sheet

Abstract

A waterproof sound-transmitting sheet, which interposes an adhesive layer composed of a material having micropores formed therein, thus smoothing the flow of the air between a waterproof sound-transmitting layer and a support layer. The waterproof sound-transmitting sheet includes a waterproof sound-transmitting layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof sound-transmitting layer, and a support layer having one surface adhered to the other surface of the adhesive layer; and the adhesive layer includes a substrate having a pore formed therein and an adhesive agent formed on both surfaces of the substrate.

1 - 10 . (canceled) 
     
     
         11 . A waterproof sound-transmitting sheet, comprising:
 a waterproof sound-transmitting layer;   a support layer which is a nonporous film having a plurality of discharge holes formed therein; and   an adhesive layer interposed between the waterproof sound-transmitting layer and the support layer to be adhered to one surface of the waterproof sound-transmitting layer and one surface of the support layer,   wherein the adhesive layer having an airflow passage that allows airflow to pass therethrough.   
     
     
         12 . The waterproof sound-transmitting sheet of  claim 11 , wherein the adhesive layer includes a plurality of pores that constitute the airflow passage. 
     
     
         13 . The waterproof sound-transmitting sheet of  claim 11 , wherein the adhesive layer comprises
 a substrate including a plurality of pores formed therein, the plurality of pores constituting the airflow passage; and   an adhesive agent formed on both surfaces of the substrate.   
     
     
         14 . The waterproof sound transmitting sheet of  claim 11 , wherein the adhesive layer has a hole formed therein such that the waterproof sound-transmitting layer and the support layer are disposed face-to-face by the hole of the adhesive layer. 
     
     
         15 . The waterproof sound transmitting sheet of  claim 11 , wherein the adhesive layer has a hole formed therein such that the support layer is disposed to be spaced apart from the waterproof sound transmitting layer by the hole of the adhesive layer.
