Abstract:
[Problem] To provide is a water-resistant sound transmitting member which has a high degree of water resistance, which can be suitably used for the water-resistance protection of a microphone and a speaker for an electrical appliance, and with which, even when used in a compressed state in order to prevent sound interference within a housing, acoustic loss is low and the acoustic characteristics of a microphone and a speaker are not impaired. [Solution] In this water-resistant sound transmitting member, a support layer is layered on at least one surface of a water-resistant sound transmitting film, a sound transmitting region where both surfaces of the water-resistant sound transmitting film are exposed is provided, and the stress on the film surface of the water-resistant sound transmitting member necessary to compress the same by 40% in the vertical direction is 1-600kPa.
