[0030] The following is combined Figures 1-3 This invention describes the specific structure and working principle of the transducer of this utility model.

[0031] Figure 1 A three-dimensional structural schematic diagram of the transducer provided by this utility model is shown in the figure. Figure 2 A side view of the transducer provided by this utility model is illustrated. Figure 3 A top view of the transducer provided by this utility model is shown in the example. Figures 1 to 3 As shown, the transducer includes a flange 100, a housing 200, and an electroacoustic conversion device 300. The housing 200 is disposed on one side of the flange 100 and is sealed to the flange 100. The cross-section of the housing 200 parallel to the flange 100 is the cross-section of the housing 200. The width of the cross-section increases and then decreases from the first end of the housing 200, wherein the first end is arc-shaped, and the other end opposite to the first end is arc-shaped or conical. The electroacoustic conversion device 300 is disposed inside the housing 200 and is used for the mutual conversion of electrical energy and acoustic energy. The electroacoustic conversion device 300 is an inductive ceramic. Of course, the specific type of the electroacoustic conversion device 300 is not limited to this, and other types of devices can also be used. The electroacoustic conversion device 300 is disposed inside the housing 200.

[0032] The transducer provided by this utility model effectively reduces the resistance encountered by the transducer during the movement of underwater equipment by first increasing and then decreasing the width of the cross-section of the housing 200 along the direction of water flow; at the same time, due to the reduction of flow resistance, the regeneration noise generated by the contact between the transducer surface and the water is reduced, thereby reducing the performance of the transducer in the receiving state.

[0033] It should be noted here that the direction of water flow is the direction of water flow relative to the transducer during the transducer's movement in the water. Figure 3 The direction from left to right in the middle.

[0034] In one embodiment of this utility model, such as Figure 2As shown, the inside of the shell 200 is hollow, one side of the shell 200 is provided with an opening, and the flange 100 covers the opening and seals the opening. This facilitates the installation and removal of the electro-acoustic transducer device 300.

[0035] In an embodiment of the present application, one side of the shell 200 perpendicular to the flange 100 (i.e. Figure 3 the left side of the shell 200) is arc-shaped, so that the shell 200 has a streamlined structure. The shell 200 with a streamlined structure has a lower flow resistance, reduces the regenerative noise generated by the surface of the transducer in contact with water, and reduces the performance of the transducer in the receiving state.

[0036] In an embodiment of the present application, as shown in the drawings, Figure 1 the side of the shell 200 away from the flange 100 is a flat surface 201 to ensure that the inside of the shell 200 has a large space to install the electro-acoustic transducer device 300. The edge of the flat surface 201 is provided with a rounded corner. By rounding the edge of the flat surface 201, the flow resistance when the shell 200 contacts with water is further reduced.

[0037] In an embodiment of the present application, the side of the shell 200 away from the flange 100 is arc-shaped, and the connection between the side wall of the shell 200 and the side of the shell 200 away from the flange 100 is provided with a rounded corner, so that the connection between the side wall of the shell 200 and the side of the shell 200 away from the flange 100 forms a smooth transition. In this way, the entire shell 200 is in the shape of a water droplet, further reducing the resistance of the transducer during the movement of the underwater equipment, reducing the regenerative noise generated by the surface of the transducer in contact with water, and reducing the performance of the transducer in the receiving state.

[0038] In an embodiment of the present application, as shown in the drawings, Figure 2 the flange 100 is provided with a connecting portion for connecting with the underwater equipment. The connecting portion is provided on the flange 100 to facilitate the installation of the transducer. Specifically, the connecting portion is a threaded hole 101, and the threaded hole 101 is a blind hole. The threaded hole 101 is located on the side of the flange 100 away from the shell 200. A plurality of threaded holes 101 are provided on the edge of the side of the flange 100 away from the shell 200, and the distance between adjacent two threaded holes 101 is equal or unequal, which is determined according to actual needs. When installing the transducer, a plurality of screws are correspondingly arranged in the plurality of threaded holes 101, and the screws are matched with the threaded holes 101 to fix the transducer on the surface of the underwater equipment. Of course, the specific structure of the connecting portion is not limited to this, and can also be a positioning protrusion or other structure.

On the other hand, the characteristic impedance of the polyurethane material shell is close to water, and has little effect on acoustic propagation. The electroacoustic transducer 300 is arranged on the flange 100, and the material of the flange 100 is metal. The flange 100 made of metal material has a large hardness, and can provide better support and protection for the electroacoustic transducer 300.
