Abstract: A waterproof sound-transmitting member includes a waterproof sound-transmitting membrane and a support layer. The support layer includes a polyolefin-based resin foam. The support layer has a loss modulus of 1.0×107 Pa or less and a loss factor of 1.0×10−1 or more. The waterproof sound-transmitting membrane is, for example, a stretched porous polytetrafluoroethylene membrane. The waterproof sound-transmitting membrane may include an adhesive layer.

Abstract: A waterproof sound transmitting member according to the present invention includes: a waterproof sound transmitting membrane having a first surface and a second surface opposite to the first surface; and a first adhesive sheet and a second adhesive sheet that are disposed on the first surface. When viewed in a direction perpendicular to the first surface, the first adhesive sheet has a closed frame shape, and the second adhesive sheet is disposed within the frame formed by the first adhesive sheet and is spaced from the first adhesive sheet. This waterproof sound transmitting member has a structure suitable for preventing deterioration in sound quality due to sagging of the waterproof sound transmitting membrane.
