Claims

[Claims for Utility Model Registration] 1. A low-frequency underwater ultrasonic transducer in which a wave transmitting/receiving element is arranged within a parabolic mirror-shaped reflective concave surface, which includes: (a) a piece of wood formed into an inverted mortar shape; (b) a reflective concave body disposed below the protective body and having a reflective surface formed from a thin plate of corrosion-resistant aluminum alloy in the shape of a parabolic mirror; (C) ) a reflective material layer provided between the protective body and the reflective concave body; (d) a flange portion for holding the protective body and the reflective concave body together and for holding the support shaft described below; an upper support body having a cylindrical portion; (e) a support shaft penetrating the cylindrical portion and held at the axis of the reflective surface of the reflective concave body; and (f) fitting onto the support shaft body. A wave transmitting/receiving element and a body, in which the aforementioned wave transmitting/receiving element is created by waterproof molding a ring-shaped vibrator with a center hole for the purpose of holding the supporting shaft; (g) holding the supporting shaft; a lower support member held at the axis of the reflective surface of the reflective concave body; and (h) a plurality of lower supports having one end fixed to the lower support member and extending radially, and the other end fixed to the open end of the reflective concave body. An underwater ultrasonic transducer characterized by comprising: a trabecular rest; 2. The underwater ultrasonic transducer according to claim 1 of the above-mentioned utility model registration, which is a box containing a wave transceiver element body formed by molding a high-frequency disc-shaped vibrator on the lower surface of the lower support. An underwater ultrasonic transducer with an attached structure to the body.
