Claims

[Claims for Utility Model Registration] 1. A low-frequency underwater ultrasonic transducer in which a wave transmitting/receiving element is arranged within a reflective concave surface in the shape of a parabolic mirror, which (a) is made of wood formed into an inverted mortar shape and is waterproof; (b) a reflective surface formed from a thin plate of corrosion-resistant aluminum alloy in the shape of a parabolic mirror, which is disposed under the protective body and whose opening surface is substantially reflective; (c) a reflective material layer provided between the protective body and the reflective concave body; (d) a reflective concave body positioned at the focal point of the surface; (d) a reflective concave body positioned between the protective body and the reflective concave body; (e) an upper support member having a flange portion for holding together and a cylindrical portion for holding the support shaft described below; (f) a wave transmitting/receiving element body formed by waterproof molding a ring-shaped vibrator with a center hole for fitting into the support shaft; (g) the support (h) a lower support that holds the shaft body and is held at the axis of the reflective surface of the reflective concave body by the supporting frame described below; (h) one end is fixed to the lower support and extends radially; a plurality of support members fixed to the open end of the reflective concave body, at least the reflective concave body,
An underwater ultrasonic transducer characterized in that an upper support member is provided with water passage holes for reducing water flow resistance. 2. The underwater ultrasonic transducer according to claim 1 of the above-mentioned utility model registration, wherein a wave transceiver element body formed by molding a high-frequency disc-shaped vibrator is housed on the lower surface of the lower support. An underwater ultrasonic transducer with a structure for attaching a box body.
