Abstract: PURPOSE: An underwater sound transducer, a manufacturing method thereof, and a manufacturing mold thereof are provided to improve the water tightness of a cable which is inserted into a housing by filling a sealing member between the cable and a cable housing. CONSTITUTION: A cable(141) supplies a signal and a power source to a piezoelectric element. The cable is connected to the piezoelectric element through a cable passage(123a) which is formed in the rear opening of the housing. A cable housing(142) is arranged to be adjacent to the rear opening of the housing. A sealing member(143) is formed between the cable and the cable housing. The sealing member prevents fluid from being penetrated into the boundary surface of the cable housing and the cable. The sealing member is able to be integrally combined with the cable and the cable housing. A screw nut(144) is combined with the housing. The screw nut firmly combines the cable, the cable housing, and the sealing member with the housing.

Abstract: PURPOSE: An underwater sound transducer, a manufacturing method thereof, and a manufacturing mold thereof are provided to improve water tightness between a front weight and an acoustic window by integrally combining the acoustic window with the front weight. CONSTITUTION: A surface process for a front weight is performed(S100). The front weight is settled in an internal space(S200). The front weight is placed in a mold with a space to integrally combine the one side of the front weight with the acoustic window. A melted material, which forms the acoustic window, is inserted into the mold(S300). The acoustic window, which is integrally combined with the one side of the front weight, is formed by closing the mold(S400).

Abstract: PURPOSE: An underwater sound transducer, a manufacturing method thereof, and a making mold of the same are provided to arrange a decoupling device between an external cylinder fixed in a housing and an inner cylinder adjacent to a piezoelectric device, thereby supporting a vibration body. CONSTITUTION: An underwater acoustic transducer detects the position and distance of an object by sensing a sound wave reflected from the object. The underwater acoustic transducer includes a vibration body, a housing, an acoustic window, and a decoupling device assembly(150). The housing is arranged into a cylindrical shape including a hollow hole. The housing is arranged in order to store a piezoelectric device. An external cylinder(152) is fixed in the housing from the one end of the piezoelectric device. An internal cylinder(151) is touched with the one end of the piezoelectric device in the inside of the external cylinder. A decoupling device(153) is arranged between the outer circumference of the internal cylinder and the inner circumference of the external cylinder in order to absorb external impact.
