[0039] With the increasing popularity of underwater activities such as recreational sports, competitive sports, and scientific research, people have begun to consider how to achieve communication underwater. However, in the underwater environment, communication between people is blocked by water, and communication between people and smart devices is also affected by water.

[0040] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of an underwater communication device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a signal processing component provided in an embodiment of this application. Figure 3 This is a schematic diagram of a processing chip module structure provided in an embodiment of this application. Figure 4 This is a schematic diagram of an underwater communication device with an antenna extension line provided in an embodiment of this application.

[0041] This application provides an underwater communication device 100 to solve the technical problem that communication between people and between people and smart terminals 2000 is affected by water in an underwater environment.

[0042] It should be noted that the underwater communication device 100 described in this application includes, but is not limited to, devices such as diving masks 200 for user use. For example, the underwater communication device 100 can also be applied to diving robots or other structures, and this application does not limit this.

[0043] The underwater communication device 100 includes a communication component 10, an antenna component 20, and a signal processing component 30. The communication component 10 is used for audio acquisition and playback. The antenna component 20 is used for transmitting and receiving signals. The signal processing component 30 is electrically connected to both the communication component 10 and the antenna component 20.

[0044] The signal processing component 30 is capable of processing the audio collected by the communication component 10 and forming a first preset signal, and the antenna component 20 is capable of transmitting the first preset signal; the signal processing component 30 is capable of processing the signal received by the antenna component 20 and forming a second preset signal, and the communication component 10 plays audio according to the second preset signal.

[0045] The communication component 10 is used for audio acquisition and audio playback. In other words, the communication component 10 can be used to acquire and pick up the user's voice or other audio, and the communication component 10 can also be used to play audio (including but not limited to audio for calls, music, etc.) so that the user can hear the sound underwater.

[0046] Specifically, the communication component 10 includes a microphone 12, a first audio line 11, a speaker 14, and a second audio line 13.

[0047] The microphone 12 is connected to the signal processing component 30 via the first audio cable 11, and the microphone 12 is used for audio acquisition. For example, the microphone 12 can be used to acquire and pick up the user's voice or other audio. It should be noted that the microphone 12 can be placed inside the user's mouth or as close as possible to the user's mouth or throat.

[0048] Optionally, the microphone 12 includes a vibration sensor.

[0049] The speaker 14 is connected to the signal processing component 30 via the second audio cable 13, and the speaker 14 is used for audio playback. For example, the speaker 14 can be used to play audio such as calls and music. It should be noted that the speaker 14 can be placed close to the user's ear.

[0050] Optionally, the speaker 14 includes a bone conduction speaker or a piezoelectric ceramic speaker.

[0051] The underwater communication device 100 of this application further includes an antenna assembly 20, wherein the antenna assembly 20 is used for transmitting and receiving signals. Specifically, the antenna assembly 20 is used for transmitting signals, in other words, the antenna assembly 20 is capable of converting electrical signals into electromagnetic waves that propagate in a medium; the antenna assembly 20 is also used for receiving signals, in other words, the antenna assembly 20 is capable of capturing electromagnetic waves in the air and converting them into electrical signals. It should be noted that, in this embodiment, at least a portion of the antenna assembly 20 may protrude above the water surface and transmit or receive electromagnetic waves in the air, thereby improving the electromagnetic wave transmission and reception efficiency of the antenna assembly 20.

[0052] The underwater communication device 100 of this application further includes the signal processing component 30, which is capable of processing the audio collected by the communication component 10 and forming a first preset signal, and the antenna component 20 is capable of transmitting the first preset signal; the signal processing component 30 is capable of processing the signal received by the antenna component 20 and forming a second preset signal, and the communication component 10 plays audio according to the second preset signal.

[0053] Furthermore, the user can transmit and receive sound through the underwater communication device 100. Specifically, when the user transmits sound through the underwater communication device 100, the microphone 12 can be used to collect and pick up the user's voice or other audio, and form a first audio analog signal. The signal processing component 30 can digitize the first audio analog signal and convert it into a first preset signal. The antenna component 20 can convert the first preset signal into electromagnetic waves and transmit them. When the user receives sound through the underwater communication device 100, the antenna component 20 can capture electromagnetic waves in the medium and convert them into a second preset signal through the signal processing component 30. The communication component 10 can convert the second preset signal into a second audio analog signal. The speaker 14 restores the second audio analog signal to sound, realizing the output of voice or audio information.

[0054] It should be noted that users can communicate and converse with two or more people underwater using the underwater communication device 100 described in this application. For example, one user can use one of the underwater communication devices 100 to communicate with another user using another of the underwater communication devices 100, or multiple users can use their respective underwater communication devices 100 to achieve collective communication.

[0055] The underwater communication device 100 described in this application can realize two-way voice communication underwater. Through a closed-loop process of audio acquisition, signal processing, wireless transmission, and audio playback, divers, underwater robots, and others can exchange voice information in real time underwater, solving the problems of low efficiency and limited range of gesture communication used in traditional underwater communication.

[0056] The underwater communication device 100 provided in this application includes a communication component 10, an antenna component 20, and a signal processing component 30. The communication component 10 is used for audio acquisition and playback. The antenna component 20 is used for transmitting and receiving signals. The signal processing component 30 is electrically connected to both the communication component 10 and the antenna component 20. Specifically, the signal processing component 30 processes the audio acquired by the communication component 10 and generates a first preset signal, which the antenna component 20 then transmits; the signal processing component 30 also processes the signals received by the antenna component 20 and generates a second preset signal, which the communication component 10 then plays audio based on. Users of the underwater communication device 100 can transmit and receive sound underwater, enabling two-way underwater voice communication and solving the problems of low efficiency and limited range associated with traditional underwater gesture communication.

[0057] Please refer to Figures 1 to 4 In one embodiment, the signal processing component 30 includes a processing chip 31, which includes a receiving module 311, a processing module 312, and a transmitting module 313. The receiving module 311 is connected to the microphone 12 and the antenna assembly 20, and the transmitting module 313 is connected to the speaker 14 and the antenna assembly 20.

[0058] The receiving module 311 amplifies and filters the input signal to adapt to the input range of the subsequent processing module 312. The input of the receiving module 311 is connected to the microphone 12, allowing for the digitization of the first analog audio signal acquired by the microphone 12. The input of the receiving module 311 is also connected to the antenna assembly 20, enabling it to digitize the electromagnetic waves acquired by the antenna assembly 20. The receiving module 311 can also distinguish between the first analog audio signal from the microphone 12 and external communication signals from the antenna assembly 20, ensuring that the processing module 312 correctly identifies the signal type.

[0059] The processing module 312 has its input connected to the receiving module 311 for receiving the preprocessed signal from the receiving module 311, and its output connected to the transmitting module 313 for transmitting the processed signal. The processing module 312 encodes and modulates the first analog audio signal collected by the microphone 12 to form the first preset signal. The processing module 312 also demodulates and decodes external signals (such as electromagnetic waves) received by the antenna assembly 20 to restore the second preset signal.

[0060] The input terminal of the transmitting module 313 is connected to the processing module 312 and is used to receive the processed signal by the processing module 312. The output terminal of the processing module 312 is connected to the horn 14 and the antenna assembly 20 and is used to output the first preset signal and the second preset signal.

[0061] In one embodiment, the signal processing component 30 further includes a housing 32, within which the processing chip 31 is disposed. The housing 32 serves to protect the processing chip 31, preventing damage or short circuits caused by collisions with external objects.

[0062] Optionally, the material of the housing 32 may include, but is not limited to, plastic, metal alloy, etc. The interior of the housing 32 forms a closed cavity, which is used to accommodate the processing chip 31.

[0063] Please refer to Figures 1 to 4 In one embodiment, the underwater communication device 100 further includes a float, to which the antenna assembly 20 is fixed so that at least a portion of the antenna assembly 20 is exposed above the water surface.

[0064] The floating component is an auxiliary structural component of the underwater communication device 100. The floating component is made of lightweight, water-resistant materials (such as foam or buoy materials) and has buoyancy characteristics, which can make the antenna assembly 20 connected to the floating component float stably on the water surface.

[0065] The antenna assembly 20 is fixed to the top or side of the float by a mechanical structure (such as a buckle, bolt, etc.) to ensure that the antenna assembly 20 remains vertical or at a specific angle in the water, and at least part of the antenna assembly 20 is exposed above the water surface. Optionally, the top of the antenna assembly 20 is exposed above the water surface by 1cm-20cm. For example, the top of the antenna assembly 20 is exposed above the water surface by 1cm, 2cm, 5cm, 7cm, 8cm, 10cm, 12cm, 15cm, 18cm, 20cm, or other values ​​within the range of 1cm-20cm.

[0066] Firstly, underwater electromagnetic waves attenuate severely (especially in seawater), and the signal transmission efficiency is extremely low when the antenna assembly 20 is completely submerged. The floating component allows the antenna assembly 20 to partially protrude above the water surface, using the air medium above the water surface to transmit radio signals (such as FM, Bluetooth, radio frequency signals, etc.), significantly improving the signal strength and stability received by the antenna assembly 20.

[0067] Secondly, when the user or equipment moves underwater, the floating component floats with the water flow, preventing the antenna assembly 20 from being damaged by collisions with reefs, vegetation, or entanglement with ropes. Furthermore, the floating component can be equipped with eye-catching color markings or reflective materials, allowing for rapid location of the underwater communication device 100 even in low-visibility waters (such as muddy waters or at night) via visual inspection or radar.

[0068] Please refer to Figures 1 to 4 In one embodiment, the underwater communication device 100 further includes an antenna extension line 40, one end of which is connected to the signal processing component 30, and the other end of which is connected to the antenna component 20. The dimension D1 of the antenna extension line 40 satisfies: 0.1m ≤ D1 ≤ 5m. In other words, the underwater communication device 100 can receive or transmit communication signals in an area of ​​0.1m-5m below the water surface.

[0069] Optionally, the dimensions of the antenna extension line 40 can be 0.1m, 0.3m, 0.5m, 0.8m, 1m, 1.3m, 1.5m, 1.7m, 2m, 2.2m, 2.5m, 2.9m, 3m, 3.2m, 3.5m, 3.6m, 4m, 4.4m, 4.5m, 4.6m, 5m, or other values ​​within the range of 0.1m to 5m. This application does not impose any restrictions on these dimensions.

[0070] Please refer to Figures 1 to 4 In one embodiment, the underwater communication device 100 further includes a first seal for housing the signal processing component 30, and the first seal has a first opening, the shape of which corresponds to the shape of the first audio line 11 and the second audio line 13. The first opening is used to allow at least a portion of the first audio line 11 and the second audio line 13 to pass through and connect the speaker 14 and the microphone 12. The first seal also has a second opening, the shape of which corresponds to the shape of the antenna assembly 20. The second opening is used to allow at least a portion of the antenna assembly 20 to pass through and extend above the water surface.

[0071] The first sealing element is a waterproof shell, and its material includes, but is not limited to, plastic, metal alloy, etc. The interior of the first sealing element forms a closed cavity, which is used to house the signal processing component 30.

[0072] The first seal has the first opening, the shape of which is adapted to the first audio cable 11 and the second audio cable 13 (the audio transmission line connecting the speaker 14 and the microphone 12). Furthermore, the edge of the first opening is provided with a sealing ring or sealant to ensure the sealing when the cable passes through.

[0073] The first seal has a second opening, the shape of which is adapted to the cable of the antenna assembly 20. Furthermore, the edge of the second opening is provided with a sealing ring or sealant to ensure a seal when the cable passes through.

[0074] Firstly, the sealing cavity of the first sealing member completely isolates the signal processing component 30 from the external water environment, preventing seawater and moisture from entering and causing short circuits or corrosion in the circuits of the signal processing component 30, thereby improving the working stability and safety of the signal processing component 30.

[0075] Secondly, the first sealing element can be made of metal, and it can form a Faraday cage effect, shielding the signal processing component 30 from interference from stray electromagnetic signals (such as weak electromagnetic signals generated by seawater flow). The signal processing component 30 within the first sealing element is isolated from the external environment, reducing electromagnetic leakage during audio signal transmission and improving the clarity and accuracy of the underwater communication device 100. The first sealing element also provides rigid support for the signal processing component 30, preventing loosening of components or breakage of wiring caused by underwater movements by the user.

[0076] Please refer to Figures 1 to 8 , Figure 5 This is a schematic diagram of a microphone disposed within a second sealing member, according to an embodiment of this application. Figure 6 This is a schematic diagram of the structure of a microphone provided in an embodiment of this application. Figure 1 , Figure 7 This is a schematic diagram of the structure of a microphone provided in an embodiment of this application. Figure 2 , Figure 8 This is a schematic diagram of the structure of a microphone provided in an embodiment of this application. Figure 3 .

[0077] In one embodiment, the underwater communication device 100 may further include a second seal 50 and a third seal, the second seal 50 being used to receive and seal the microphone 12, and the third seal being used to receive and seal the speaker 14.

[0078] In one embodiment, the second sealing member 50 can enclose the microphone 12, and the second sealing member 50 is made of a soft elastic film material (such as silicone). A sealed cavity is formed inside the second sealing member 50, and the microphone 12 is disposed in the sealed cavity. The second sealing member 50 is placed near the sound-producing part or directly into the mouth. The vibration of the sound will cause the elastic film to vibrate, which in turn will cause the air inside the second sealing member 50 to vibrate. The microphone 12 thus picks up the sound. Due to its elastic film characteristics, its volume will change with pressure, which can automatically balance the pressure inside the second sealing member 50. This not only seals the microphone 12 for waterproofing, but also helps to improve the sound reception quality and reception efficiency of the microphone 12.

[0079] Furthermore, in one embodiment, the microphone 12 is a unidirectional microphone, and the microphone 12 includes a diaphragm 121, with holes on both sides of the diaphragm 121 for air communication. Specifically, the microphone includes an opening 122 that communicates with the space where the diaphragm 121 is located, which helps to balance the pressure on both sides of the diaphragm 121 and avoids damage such as rupture of the diaphragm 121 due to uneven pressure on both sides.

[0080] Please refer to Figures 1 to 9 , Figure 9 This is a schematic diagram of the structure of an underwater communication device provided in an embodiment of this application.

[0081] This application also provides an underwater communication device, which includes a mask 200 and an underwater communication device 100, wherein the underwater communication device 100 is disposed on the mask 200.

[0082] In one embodiment, the microphone 12 and the speaker 14 of the communication component 10 can be fixed to the mask 200. In another embodiment, the microphone 12 and / or the speaker 14 of the communication component 10 can also be embedded inside the mask 200, close to the user's face, protecting the microphone 12 from water flow noise interference and improving the clarity of voice acquisition. In one embodiment, the microphone 12 can be located in the mouth and nose area of ​​the mask 200 for acquiring the user's vocal audio. In one embodiment, the speaker 14 can be placed near the user's ear. In one embodiment, the signal processing component 30 can be fixed to the side or rear of the mask 200 by clips or magnets, preventing the signal processing component 30 from encountering obstacles underwater that could affect the user's diving experience or damage the signal processing component 30.

[0083] The underwater communication device 100 and the mask 200 are integrated to form the underwater communication equipment, so the user does not need to hold the additional underwater communication device 100.

[0084] The underwater communication device provided in this application includes a mask 200 and an underwater communication device 100. The underwater communication device 100 includes a communication component 10, an antenna component 20, and a signal processing component 30. The communication component 10 is used for audio acquisition and playback. The antenna component 20 is used for transmitting and receiving signals. The signal processing component 30 is electrically connected to both the communication component 10 and the antenna component 20. Specifically, the signal processing component 30 can process the audio acquired by the communication component 10 and form a first preset signal, and the antenna component 20 can transmit the first preset signal; the signal processing component 30 can also process the signals received by the antenna component 20 and form a second preset signal, and the communication component 10 plays audio according to the second preset signal. Users can use the underwater communication device of this application to send and receive sound underwater, achieving two-way voice communication underwater and solving the problems of low efficiency and limited range of traditional underwater communication using gesture communication.

[0085] Please refer to Figures 1 to 9 In one embodiment, the mask 200 includes a snorkeling mask, the mask 200 includes an air duct 210, and the antenna assembly 20 is fixed to the air duct 210 such that at least a portion of the antenna assembly 20 is exposed above the water surface.

[0086] Optionally, in this embodiment, the antenna assembly 20 is fixed to the outer wall of the air duct 210 (near the end of the duct opening) by means of a buckle, cable tie or injection molding process, so as to ensure that when the air duct 210 is exposed above the water surface, the top of the antenna assembly 20 is exposed above the water surface by 1cm-20cm.

[0087] Please refer to Figures 1 to 11 , Figure 10 This is a schematic diagram of the structure of an underwater communication system provided in an embodiment of this application.

[0088] This application also provides an underwater communication system, which includes a smart terminal 2000 and the underwater communication device, wherein the underwater communication device is capable of communicating with the smart terminal 2000.

[0089] Specifically, in this embodiment, the smart terminal 2000 includes a Bluetooth device, allowing the user to bring the antenna assembly 20 of the underwater communication device 100 close to the smart terminal 2000 to enable communication between the user and the smart terminal 2000.
