[0018] The drawings described herein are used to provide a further understanding of the present application and constitute a part of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application.

[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0022] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit this application. They are merely used to distinguish components or operations described with the same technical terms.

[0023] For ocean and deep-sea exploration, it is necessary to use low-frequency, high-power underwater acoustic transducers to generate sound signals that propagate in the water medium. After encountering the target, the sound is reflected back for reception and converted into electrical signals for listening or observation, thereby determining the direction and distance of the object. However, my country has almost no technical solutions in this area.

[0024] The energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer of the present application is mainly suitable for the open ocean and deep sea. It integrates a micro sound source on the pressure-resistant glass to form a surface sound-generating structure, which will not cause pollution to the ocean and is convenient to use. The underwater acoustic transducer of the present application can be placed according to the coverage range, so that the ocean can be gradually effectively controlled, thereby better exploring the ocean.

[0025] See also Figure 1 , which is a schematic diagram of an energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer according to an embodiment of the present application. As shown in the figure, the energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer 1 includes a pressure-resistant glass 2, a reliability structure 3, and a micro sound source 4. The pressure-resistant glass 2 has a hollow cavity. The reliability structure 3 and the micro sound source 4 are arranged in the hollow cavity. The pressure-resistant glass 2 can withstand at least 700 atmospheres of pressure, so that it can be used on a submarine and is suitable for ocean and deep-sea exploration.

[0026] One side of the reliability structure 3 is bonded to one side of the pressure-resistant glass 2. In this embodiment, the pressure-resistant glass 2 also has a lower pressure-resistant glass 21 and an upper pressure-resistant glass (not shown in the figure), the micro-sound source 4 is bonded to the lower pressure-resistant glass 21, the reliability structure 3 is bonded to the upper pressure-resistant glass, and the lower pressure-resistant glass 21, the micro-sound source 4, the reliability structure 3 and the upper pressure-resistant glass form a four-layer bonding structure. The micro-sound source 4 includes a plurality of micro-sound source units (not shown in the figure). One side of the plurality of micro-sound source units is bonded to the other side of the pressure-resistant glass 2, that is, the lower pressure-resistant glass 21, using the principle of concentricity sound field concentration, so that the low-frequency propagation can be ensured to be stable and have a wide range of influence. Each micro-sound source unit uses electromagnetic components, which are different from piezoelectric ceramics, have a short life and are easily damaged. Such devices can withstand 700 atmospheres of pressure.

[0027] Specifically, see Figure 2 , which is a schematic diagram of a plurality of electromagnetic components arranged in a circular shape according to an embodiment of the present application. As shown in the figure, a plurality of electromagnetic components are arranged in a circular shape according to Figure 2 The micro-electromagnetic components are arranged in a circular shape in the hollow cavity. It is only necessary to fit a single electromagnetic component to the lower pressure-resistant glass 21, thereby reducing the requirements for the cavity manufacturing process. And because the miniature sound source 4 is densely assembled from single electromagnetic components, the mutual coupling phenomenon between the micro-electromagnetic components is reduced, and independent control of each electromagnetic component can be achieved. At the same time, the micro-electromagnetic array used in this embodiment no longer requires the electromagnetic components to be located on an infinitely long rigid cylinder, so the actual micro-electromagnetic model is closer to the theoretical model, and the realization error of directional sound radiation is smaller. The micro-electromagnetic array used in this embodiment has a limited height, so it is applicable to a wider range of scenarios.

[0028] The other side of the reliability structure 3 is attached to the other side of the multiple micro sound source units. The reliability structure 3 includes a first waterproof and moisture-proof layer 31, a second waterproof and moisture-proof layer 32, a third waterproof and moisture-proof layer 33, and a fourth waterproof and moisture-proof layer 34 stacked in sequence, the first waterproof and moisture-proof layer 31 is attached to the pressure-resistant glass 2, and the other side of the multiple micro sound source units is attached to the fourth waterproof and moisture-proof layer 34. The waterproof functions of the fourth waterproof and moisture-proof layer 34, the third waterproof and moisture-proof layer 33, the second waterproof and moisture-proof layer 32, and the first waterproof and moisture-proof layer 31 are enhanced in sequence.

[0029] As mentioned above, the fourth waterproof and moisture-proof layer 34 uses a super strong waterproof film. The third waterproof and moisture-proof layer 33 uses liquid. In other words, the third waterproof and moisture-proof layer 33 is a liquid layer, which is not only waterproof and moisture-proof, but also can ensure the stability of the internal gas. The second waterproof and moisture-proof layer 32 uses a super silicone structure, which is a new type of hybrid material. The upper and lower ends of the super silicone structure are provided with strong adhesive and the end contacting the product has the function of absorbing water and preventing moisture. The first waterproof and moisture-proof layer 31 uses pressure-resistant glue, which is a super strong water-curable glue. The above structure has high plasticity and can be designed and used according to the working state, but is not limited to this.

[0030] In one embodiment, the energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer 1 further includes a PCB board (not shown in the figure). The PCB board is electrically connected to a plurality of micro sound source units, and the PCB board is configured to convert and calculate sound energy, so that various sound energy conversion and calculation processing functions can be easily realized, but not limited thereto.

[0031] The energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer 1 of this embodiment utilizes electromagnetic components to realize the sound of large-sized glass. Because it is a surface sound, the sound wave propagates farther and is more environmentally friendly. At the same time, since the frequency range of low-frequency transducers on the market is roughly tens of hertz to 4 kilohertz, the depth exceeds 500 meters, and the generally required working voltage needs to be above 1000V, and it belongs to point or line sound source sound, the sound pressure decreases more seriously with the increase of distance, and the closer the distance, the louder the sound pressure, which may cause close-range sound pollution. In addition, the current transducer operating temperature is generally -2 degrees Celsius to 50 degrees Celsius, and the storage temperature is -20 degrees Celsius to 50 degrees Celsius. As time goes by, the metal layer will rust and naturally damage.

[0032] The underwater acoustic transducer 1 of the embodiment integrates electromagnetic components into the hollow structure of the pressure-resistant glass 2. In addition to solving the above-mentioned current shortcomings, it also utilizes innovative technology, combining the electromagnetic unit with the pressure-resistant glass to ultimately achieve surface sound generation. In this way, as long as the glass on the current submarine can withstand a certain atmospheric pressure, we can ultimately achieve the corresponding effect of the transducer. It is also easy to install and can be pushed to a depth of 10,000 meters to further study the deep sea.

[0033] Taking 500 meters below the seabed as an example, the performance parameters of the low-frequency transducer currently on the market and the underwater acoustic transducer of this embodiment are compared as follows:

[0034]

[0035]

[0036] In summary, the present application provides an energy-saving, environmentally friendly, low-frequency, high-power underwater acoustic transducer, which integrates a micro sound source on pressure-resistant glass to form a surface sound-generating structure, so that the sound waves can propagate farther, will not pollute the ocean, and is relatively convenient to use. At the same time, as long as the glass on the current submarine can withstand a certain atmospheric pressure, we can eventually achieve the corresponding effect of the transducer, and it is easy to install and can be pushed to a depth of 10,000 meters to further study the deep sea.

[0037] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0038] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
