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.
Claims4
A waterproof sound-transmitting sheet, comprising:
- a waterproof sound-transmitting layer formed of a non-porous film having elasticity;
- a support layer which is a nonporous film having a plurality of discharge holes formed therein and disposed on one surface of the waterproof sound-transmitting layer;
- a first adhesive layer adhered to the other surface of the waterproof sound-transmitting layer;
- a second adhesive layer interposed between the waterproof sound-transmitting layer and the support layer to be adhered to the one surface of the waterproof sound-transmitting layer and one surface of the support layer;
- and
- a third adhesive layer disposed on the other surface of the support layer,
- wherein the second adhesive layer having a plurality of pores, and
- wherein the plurality of pores of the second adhesive layer constitutes an airflow passage that makes air in an internal space formed among the waterproof sound-transmitting layer, the second adhesive layer, and the support layer flow outside of the internal space.
