[Scope of Claim for Utility Model Registration] (1) An underwater receiving device consisting of an electroacoustic transducer having positive and negative electrodes formed on both sides of a membrane piezoelectric material and covered with waterproof rubber, which is mounted on a pedestal. In the underwater transducer, a metal plate parallel to the acoustic transducer is arranged between the electroacoustic transducer and the pedestal in the waterproof rubber layer on the pedestal side separated by the electroacoustic transducer. Receiver. (2) In an underwater receiver in which a metal plate is arranged between the acoustic transducer element and the pedestal, the waterproof rubber layer between the metal plate and the pedestal is the rubber layer that forms the waterproof rubber layer of other parts. 2. The underwater receiver according to claim 1, wherein the underwater receiver is made of at least one type of waterproof rubber having different hardness.
