Example Embodiment
[0028] Example 1:
[0029] Such as figure 1 As shown, the structural schematic diagram of the low-frequency high-power underwater sounder provided by this embodiment includes a sounder housing 2, which is open on one side, and a first diaphragm 3 and a second diaphragm are arranged at the opening. The diaphragm 4, the first diaphragm 3 and the second diaphragm 4 are tightly connected, the first diaphragm 3 is arranged on the outside, and the second diaphragm 4 is arranged on the inside; a magnetic material 11 is arranged inside the sound generator housing 2, The outside of the magnetic material 11 is enclosed by the first magnetic material 10a and the second magnetic material 10b. The first magnetic material 10a and the second magnetic material 10b can be formed on the enclosed surface facing the second diaphragm 4 Insert one end of the voice coil 6 into the gap, and the other end of the voice coil 6 is connected to the second diaphragm 4; wherein the two end faces of the first d...
Example Embodiment
[0031] Example 2
[0032] This embodiment is a further improvement on the basis of embodiment 1, such as figure 2 As shown, it also includes a cooling cycle heat exchange pipe 7, a pressure balance pipe 8 and an electromagnetic control valve 9. The cooling cycle heat exchange pipe 7 is wrapped around the voice coil 6, and its ends are connected with the electromagnetic control valve 9 to form a cooling circulation loop. One end of the pressure balance pipe 8 is set at the bottom end of the sound generator housing 2, and the other end is connected to the electromagnetic control valve 9; the magnetic material 11 is neodymium iron boron, which can provide good magnetism, and the sound generator housing 2 is provided with a magnetic circuit fixed inside One end of the magnetic circuit fixing frame 12 is fixedly connected to the first magnetic conductive material 10a, and the other end is fixedly connected to the inner wall of the sound generator housing 2; a temperature sensor 14 is...
