Detailed implementation manners

[0081] For the purposes of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art fall within the protection scope of the present invention.

[0082] An embodiment of the present invention provides a diving device, which includes an air cylinder 400, an air pipe 410, a voice cable 700, a communication module 300, a headset 600, and a microphone module 190. The air pipe 410 is communicated with the air cylinder 400; the voice cable 700 is fixed on the air pipe 410; the communication module 300 is installed on the air cylinder 400 and is electrically connected to the voice cable 700. The communication module 300 is used for receiving a first wireless signal; the headset 600 is electrically connected to the voice cable 700 and is used for playing a first audio signal generated based on the first wireless signal; the microphone module 190 is electrically connected to the voice cable 700, and the microphone module 190 is used for collecting a second audio signal; the communication module 300 is further used for sending a second wireless signal generated based on the second audio signal.

[0083] In practical applications, the diving device further includes an above-water communication component (also known as a deck box) at least partially located above water. The above-water communication module 300 can be installed on a ship and is used for establishing a communication connection with the communication module 300 located underwater. The above-water communication component, the communication module 300, the voice cable 700, the headset 600, the microphone module 190, etc. together form the communication system of the diving device. The communication module 300 has the function of transmitting and receiving wireless signals. By using the communication module 300, not only can information interaction with the above-water communication component be realized, but also information interaction with other divers 800 in the water can be realized. Taking the communication between two divers 800 as an example, after the communication module 300 of the diving device equipped by one diver 800 receives the first wireless signal, the first wireless signal is converted into a first electrical signal, and then the headset 600 converts the first electrical signal into a first audio signal. The microphone module 190 converts the collected second audio signal into a second electrical signal, and the communication module 300 converts the second electrical signal into a second wireless signal and sends it to another diver 800 to achieve underwater information communication. Both the first electrical signal and the second electrical signal are transmitted through the voice cable 700.

[0084] The wireless signal includes but is not limited to ultrasonic signals, optical signals, magnetic signals, etc.

[0085] The air cylinder 400 has a cavity for containing air or oxygen. The air or oxygen in the air cylinder 400 is transmitted to the mouth of the diver 800 through the air pipe 400 to realize the underwater breathing of the diver 800.

[0086] Generally, such as Figure 1 and Figure 2As shown, the gas cylinder 400 is located on the back of the diver 800, which is a part of the body that is difficult to cover. By installing the communication module 300 on the gas cylinder 400, not only is the installation of the communication module 300 more convenient, but also the shielding of the communication module signal is reduced or even avoided, improving the communication quality. Moreover, the communication module 300 does not need to be in contact with the body, reducing the movement restriction on the diver 800 and providing a comfortable wearing experience.

[0087] When the communication module 300 is installed on the head or arm, the voice cable 700 exists as an independent cable, increasing the number and length of the exposed cables in the diving device. In the embodiment of the present invention, as Figure 1 and Figure 2 shown, by fixing the voice cable 700 on the air pipe 400, the voice cable 700 and the air pipe 400 can form an integral body, reducing the number and length of the exposed cables and effectively reducing the safety hazard.

[0088] Without limitation, the voice cable 700 is connected to the air pipe 400 by snap connection or adhesive connection. The voice cable 700 can be detached from the air pipe as needed. For example, during use, as Figure 2 shown, the voice cable 700 is connected to the air pipe 400 by using the buckle 760 to fix the voice cable 700 to the air pipe 400. After use, when storing the diving device, the buckle 760 can be removed to separate the voice cable 700 from the air pipe 400, facilitating storage.

[0089] In some embodiments, the diving device further includes a charger, which is electrically connected to the communication module 300 and is at least used to supply power to the communication module 300.

[0090] In some other alternative embodiments, the voice cable 700 includes a main cable 710, a first cable 730, and a second cable 720. The main cable 710 is electrically connected to the communication module 300; both ends of the first cable 730 are electrically connected to the main cable 710 and the earphone 600 respectively; both ends of the second cable 720 are electrically connected to the main cable 710 and the microphone module 190 respectively; the main cable 710 is fixed on the air pipe 400, or the main cable 710 and the second cable 720 are both fixed on the air pipe 400.

[0091] As Figure 3 shown, the first cable 730 and the second cable 720 are respectively electrically connected to one end of the main cable 710 away from the communication module 300. The voice cable 700 is substantially in a Y shape.

[0092] In practical applications, since the communication module 300 is installed on the gas cylinder 400, the setting directions of the main cable 710 and the second cable 720 are substantially the same as the setting direction of the air pipe 400, and both lead from the gas cylinder 400 to the mouth of the diver 800. Therefore, fixing the main cable 710 and the second cable 720 to the air pipe 400 respectively further increases the contact length between the voice cable 700 and the air pipe 400 compared with only fixing the main cable 710 on the air pipe 400, and further reduces the number and length of the exposed cables. Moreover, connecting the voice cable 700 to the air pipe 400 can utilize the air pipe 400 to reserve a moving length for the head movement range, reducing the restriction on the head movement range.

[0093] For the first cable 730, the first cable 730 is connected to the earphone 600, and the earphone 600 corresponds to the ear part of the head and is far from the mouth. Not fixing the first cable 730 to the air pipe 400 is beneficial to the convenient use of the earphone 600 and reduces the restriction of the first cable 730 on the head movement range.

[0094] In some embodiments, as Figure 3 shown, the first cable 730 includes a spiral section 731 and a straight section 732. The two ends of the spiral section 731 are electrically connected to the main cable 710 and the straight section 732 respectively, and the straight section 732 is connected to the earphone 600. The spiral section 731 has elasticity and is wound in a spiral manner, presenting a substantially spiral shape. When subjected to an external tensile force, the spiral section 731 can be stretched into a straight shape, and the length of the spiral section 731 changes from L1 to L2, where L2 is greater than L1, increasing the length of the first cable 730. When the external force is withdrawn, using the elastic restoring force of the spiral section 731, the spiral section 731 returns to the spiral shape, and the length of the spiral section 731 returns from L2 to L1. The first cable 730 with this structure can meet the needs of different divers 800.

[0095] Without limitation, the number of the straight sections 732 is two, and the two straight sections 732 are substantially in a Y shape with the spiral section 731. In some embodiments, the diving device further includes a Y-shaped connection package 740 and a floating plug 750. The main cable 710 is connected to the spiral section 731 of the first cable 730 and the second cable 720 respectively through the Y-shaped connection package 740; the spiral section 731 is also connected to the two straight sections 732 respectively through the Y-shaped connection package 740, and the second cable 720 can be connected to the microphone module 190 through the floating plug 750.

[0096] In some other alternative embodiments, the diving device further includes: a mounting structure 900, the communication module 300 is mounted on the gas cylinder 400 through the mounting structure 900, and the mounting structure 900 includes: a base 100 and a bracket 200 fixed on the base 100. The bracket 200 includes a first mounting position for mounting the communication module 300. The base 100 includes a first support 110, a connecting member 140, a rotating arm 130, and a second support 120. Among them, the first support 110 is connected to the bracket 200; the connecting member 140 is pivotally connected to the first support 110; the rotating arm 130 is pivotally connected to the connecting member 140; the second support 120 has at least a locking position and an unlocking position relative to the first support 110. In the locking position, the second support 120 and the first support 110 jointly form a second mounting position 150 for mounting the gas cylinder 400. The second support 120 is located between the rotating arm 130 and the first support 110, and the rotating arm 130 abuts against the second support 120 to limit the separation of the second support 120 from the first support 110. In the unlocking position, the rotating arm 130 is separated from the second support 120, and at least part of the second support 120 can be separated from the first support 110.

[0097] As Figure 1 and Figure 2 shown, by using the mounting structure 900, it is possible to more conveniently mount the communication module 300 on the gas cylinder 400. It can be understood that the communication module 300 can also be mounted on the gas cylinder 400 through other structures such as clamps, buckles, or tapes.

[0098] As Figures 4 to 7 shown, the connecting member 140 is located between the rotating arm 130 and the first support 110, providing a gap 170 for the second support 120 to be embedded between the rotating arm 130 and the first support 110, effectively ensuring the locking effect on the second support 120. Both ends of the connecting member 140 can rotate, and the rotating arm 130 is pivotally connected to the connecting member 140. When the rotating arm 130 rotates, the rotating arm 130 drives the connecting member 140 to rotate, and the rotating arm 130 and the connecting member 140 form a folding structure. This folding structure not only facilitates the locking or unlocking of the second support 120, but also can effectively maintain the locking position of the second support 120, ensuring the reliability of the connection between the second support 120 and the first support 110.

[0099] In practical applications, the communication module 300 can be first mounted in the first mounting position, and then the mounting structure 900 can be fixed on the gas cylinder 400. During this process, when installing with the gas cylinder 400, along the first direction (the first direction can be Figure 6Rotate the rotating arm 130 in the clockwise direction (as shown), the rotating arm 130 drives the connecting member 140 to rotate, increasing the gap 170 between the rotating arm 130 and the first support 110, moving the second support 120 into the gap 170 between the rotating arm 130 and the first support 110, and then rotating the rotating arm 130 in the second direction opposite to the first direction (the second direction can be Figure 6 the counterclockwise direction as shown), so that the rotating arm 130 abuts against the second support 120, clamping the second support 120 between the rotating arm 130 and the first support 110, achieving the locking of the second support 120 and completing the installation process. When disassembling, rotate the rotating arm 130 in the first direction again to increase the gap 170 between the rotating arm 130 and the first support 110, so as to facilitate the separation of the second support 120 from the first support 110.

[0100] In the embodiment of the present invention, the installation of the components at the second installation position 150 can be achieved by moving the second support 120 and the rotating arm 130, without the need to rely on other disassembly and assembly tools, and the disassembly and assembly are convenient and fast.

[0101] Without limitation, the materials of the bracket 200 and the base 100 can both be metal or plastic.

[0102] In the locked position, the installation structure 900 can fix the communication module 300 and the gas cylinder 400 through the first installation position and the second installation position 150. In the unlocked position, the second installation position 150 cannot be formed. At this time, the installation structure 900 cannot perform the function of installation and fixation. The unlocked position can be used to disassemble the installation structure 900. After disassembling the installation structure 900, the communication module 300 is also separated from the gas cylinder 400 at the same time.

[0103] In the locked position, the gas cylinder 400 is located in the second installation position 150, and the first support 110 and the second support 120 jointly abut against the gas cylinder 400, realizing the function of fixing the installation structure 900 on the gas cylinder 400.

[0104] Figure 4 and Figure 7 Exemplarily shows a schematic structural diagram of the installation structure in the locked position. Figure 6 Exemplarily shows a schematic structural diagram of the installation structure in the unlocked position. Figure 5 Located between the locked position and the unlocked position, at this time, the rotating arm 130 has an interference effect in the direction of the separation of the second support 120 from the first support 110. Although the second support 120 cannot be separated from the first support 110, at this time, the fixing of the gas cylinder 400 by the first support 110 and the second support 120 is lower than that in the locked position.

[0105] Without limitation, the first mounting position may be a plane, a hole or a groove, and the communication module 300 can be fixed to the first mounting position by using fasteners such as bolts.

[0106] Without limitation, as Figure 4 and Figure 7 shown, the second mounting position 150 is a hole, the first support 110 includes a first arc surface 111, and the second support 120 includes a second arc surface 1211. In the locked position, the first arc surface 111 and the second arc surface 1211 together form the hole wall of the second mounting position 150.

[0107] Combined with Figure 2 and Figure 4 shown, when the second mounting position 150 is connected to the gas cylinder 400, in order to adapt to the gas cylinder 400, the second mounting position 150 is a substantially circular hole. It can be understood that the shape of the second mounting position 150 can also be any shape such as a square, an ellipse or a hexagon.

[0108] As Figure 4 and Figure 7 shown, in the locked position, the position where the rotating arm 130 abuts against the second support 120 is adjacent to the connection position between the rotating arm 130 and the connecting member 140. Thus, even if a large external force in the direction away from the center position of the second mounting position 150 acts on the second support 120, the second support 120 cannot easily push the rotating arm 130 to rotate, further ensuring the reliability of the connection between the second support 120 and the first support 110 in the locked position.

[0109] In some embodiments, as Figures 4 to 7 shown, the mounting structure 900 further includes: a first rotating shaft 141 and a second rotating shaft 142 respectively installed at both ends of the connecting member 140, the first support 110 is pivotally connected to the connecting member 140 through the first rotating shaft 141, and the rotating arm 130 is pivotally connected to the connecting member 140 through the second rotating shaft 142.

[0110] In some other alternative embodiments, the first end of the second support 120 is pivotally connected to the first support 110; in the locked position, the second end of the second support 120 is located between the first support 110 and the rotating arm 130; wherein, the second end is the opposite end of the first end.

[0111] As Figures 4 to 7 shown, the rotating arm 130 fixes the second end of the second support 120 between the rotating arm 130 and the first support 110 by abutting against the second end of the second support 120, thereby realizing the locking of the second support 120.

[0112] In practical applications, by rotating the second support 120 in different directions, the second end of the second support 120 can be embedded between the rotating arm 130 and the first support 110, or the second end of the second support 120 can be separated from the first support 110.

[0113] Non-limitingly, the first end of the second support 120 can be pivotally connected to the first support 110 through the third rotating shaft 143.

[0114] The first end of the second support 120 is pivotally connected to the first support 110. Even in the unlocked position, the second support 120 will not be completely separated from the first support 110, improving the integrity of the installation structure 900.

[0115] In some embodiments, the first end and the second end of the second support 120 can be separated from the first support 110 respectively. At this time, in the unlocked position, the second support 120 can be completely separated from the first support 110. The fixing method of the first end of the second support 120 to the first support 110 can be the same as that of the second end of the second support 120 to the first support 110. That is, compared with the installation structure 900 in Figures 4 to 7 When in the locked position, the first end of the second support 120 is also locked between the rotating arm 130 and the first support 110.

[0116] In some other alternative embodiments, the second support 120 has a limiting groove 1221. When in the locked position, the connecting member 140 is embedded in the limiting groove 1221; or, the connecting member 140 has a limiting groove 1221. When in the locked position, the second support 120 is embedded in the limiting groove 1221.

[0117] Take Figures 4 to 7 the second support 120 shown having a limiting groove 1221 as an example. After the connecting member 140 is embedded in the limiting groove 1221, the limiting groove 1221 can at least limit the movement of the connecting member 140 in the direction perpendicular to the base 100. And the abutment of the rotating arm 130 against the second support 120 is more conducive to restricting the movement of the second support 120 in the direction parallel to the base 100. Therefore, setting the limiting groove 1221 can further improve the connection reliability between the second support 120 and the first support 110 when in the locked position.

[0118] In some other alternative embodiments, the second support 120 includes an arc portion 121 and a limiting portion 122. When in the locked position, the arc portion 121 and the first support 110 jointly form the second installation position 150; the limiting portion 122 is connected to the arc portion 121 and protrudes in the radial direction of the arc portion 121 away from the center position of the second installation position 150. The limiting portion 122 has the limiting groove 1221; when in the locked position, the rotating arm 130 abuts against the limiting portion 122.

[0119] The first end and the second end of the second support 120 may be respectively provided with limiting portions 122, or, as Figures 4 to 7 shown, the limiting portion 122 may be provided only at the second end of the second support 120, and the first end is pivotally connected to the first support 110.

[0120] The second arc surface 1211 is located on the surface of the arc-shaped portion 121 facing the first support 110. The second support 120 fixes the gas cylinder 400 through the second arc surface 1211.

[0121] In some other alternative embodiments, when in the locking position, the rotating arm 130 is arranged along the circumferential direction of the arc-shaped portion 121.

[0122] As Figures 4 to 7 shown, the shape of the rotating arm 130 is generally arc-shaped. The shape of the rotating arm 130 may be generally the same as the shape of the arc-shaped portion 121.

[0123] The rotating arm 130 arranged along the circumferential direction of the arc-shaped portion 121 is less likely to rotate, further improving the locking effect on the second support 120 when in the locking position.

[0124] It can be understood that the longer the length of the rotating arm 130 arranged along the circumferential direction of the arc-shaped portion 121, the more beneficial it is to lock the second support 120. In some embodiments, the length of the rotating arm 130 arranged along the circumferential direction of the arc-shaped portion 121 is about 1 / 2 to 1 of the length of the arc-shaped portion 121.

[0125] In some other alternative embodiments, the mounting structure 900 further includes: a flexible member 160, located within the second mounting position 150.

[0126] The flexible member 160 is used to strengthen the connection strength between the second mounting position 150 and the gas cylinder 400.

[0127] Without limitation, the flexible member 160 may be rubber or fiber fabric, etc. Rubber includes but is not limited to silica gel.

[0128] In some other alternative embodiments, the bracket 200 has a first through hole 240; the first support 110 has a second through hole 112; the mounting structure 900 further includes a rotating shaft 210 and a limiting protrusion 220, and the rotating shaft 210 passes through the first through hole 240 and the second through hole 112 at the same time; the limiting protrusion 220 is located on the rotating shaft 210; the bracket 200 has at least an unfolded position and a folded position relative to the base 100; in the unfolded position, the limiting protrusion 220 is located in the first through hole 240 and the second through hole 112 at the same time, and the limiting protrusion 220 restricts the bracket 200 from rotating relative to the first support 110 along the axis of the rotating shaft 210; in the folded position, the limiting protrusion 220 is separated from the second through hole 112, the limiting protrusion 220 is located in the first through hole 240 and abuts against the first support 110, and the bracket 200 can rotate relative to the first support 110 along the axis of the rotating shaft 210.

[0129] In the embodiment of the present invention, the unfolded position may be the working position during diving operations. The folded position is the non-working position. Relatively speaking, when in the folded position, the mounting structure 900 occupies less space and can facilitate the storage of the mounting structure 900.

[0130] Without limitation, the rotating shaft 210 may be a folding bolt.

[0131] The limiting protrusion 220 can maintain the unfolded position of the bracket 200 and prevent the bracket 200 from rotating relative to the base 100 undesirably.

[0132] Without limitation, when in the unfolded position, the bracket 200 is perpendicular to the base 100; when in the folded position, the bracket 200 is parallel to the base 100.

[0133] Figure 4 Exemplarily shows a schematic structural diagram of the mounting structure when in the unfolded position. Figure 7 Exemplarily shows a schematic structural diagram of the mounting structure when in the folded position. Figure 6 Exemplarily shows a schematic structural diagram of the mounting structure when between the unfolded position and the folded position.

[0134] Such as Figure 5As shown, the limiting protrusion 220 is always located within the first through hole 240. Due to the anti-rotation effect of the limiting protrusion 220, the rotating shaft 210 cannot rotate around the axis of the first through hole 240 within the first through hole 240, but can move axially within the first through hole 240. By moving the rotating shaft 210, the limiting protrusion 220 can be moved into the second through hole 112 or outside the second through hole 112. When the limiting protrusion 220 is located within the second through hole 112, the limiting protrusion 220 prevents the first support 110 from rotating relative to the rotating shaft 210; when the limiting protrusion 220 is located outside the second through hole 112, the limiting protrusion 220 cannot prevent the first support 110 from rotating relative to the rotating shaft 210, and the first support 110 and the bracket 200 can rotate relative to each other, thereby realizing the transition from the unfolded position to the folded position.

[0135] In some other alternative embodiments, the mounting structure further includes: an elastic member 230, with two ends respectively connected to the bracket 200 and the rotating shaft 210; when in the folded position, the elastic member 230 is in an elastic deformation state storing elastic restoring force; when between the folded position and the unfolded position, the elastic member 230 releases the elastic restoring force.

[0136] In some embodiments, when in the folded position, the limiting protrusion 220 abuts against the first support 110. When transitioning from the folded position to the unfolded position, when the bracket 200 rotates in place or the first support 110 rotates in place, the second through hole 112 is aligned with the limiting protrusion 220 again, and under the action of the elastic restoring force of the elastic member 230, the limiting protrusion 220 automatically enters the second through hole 112.

[0137] Therefore, the elastic member 230 can automatically realize the connection between the limiting protrusion 220 and the second through hole 112, which is convenient for operation.

[0138] Without limitation, the elastic member 230 can be a spring or a spring sheet. The spring includes but is not limited to a tension spring.

[0139] The diving device further includes a breathing mouthpiece 500, and the breathing mouthpiece 500 includes: a housing 510, a fixing frame 520, a mouthpiece 521, and a mouth sleeve 530. The housing 510 has an air inlet 511 and an air outlet 512, the air inlet 511 is communicated with the air outlet 512, the air tube 410 is communicated with the air inlet 511, and the microphone module 190 is located within the housing 510; the fixing frame 520 is installed within the housing 510, and the microphone module 190 is fixed on the fixing frame 520; the mouthpiece 521 is fixed on the fixing frame 520, passes through the air outlet 512, and is at least exposed outside the housing 510; the mouth sleeve 530 is sleeved outside the mouthpiece 521.

[0140] During actual use, the air outlet 512 faces the diver's oral cavity. As Figure 8 and Figure 9 shown, the housing 510 is a hollow member, and the housing 510 also has a gas passage located between the air outlet 512 and the air inlet 511. The air inlet 511 is used to communicate with the gas cylinder, so that the gas provided by the gas cylinder 400 enters the gas passage through the air inlet 511 and then flows from the air outlet 512 to the diver 800's oral cavity, realizing the diver 800's inhalation underwater.

[0141] Generally, the rigidity of the fixing bracket 520 is greater than that of the housing 510. The fixing bracket 520 has a supporting effect on the housing 510. At the same time, the fixing bracket 520 is at least used to fix the mouthpiece 521.

[0142] In some embodiments, the cross-sectional area of the housing 510 gradually decreases from the air inlet 511 to the air outlet 512 direction. As Figure 1 , Figure 2 and Figure 8 and Figure 9 shown, the air outlet 512 part of the housing 510 that fits with the diver 800's mouth is designed to be streamlined. The outer surface of the housing 510 is generally conical, which is roughly the same as the shape of a duck's bill. This shape of the housing 510 is beneficial to reducing the resistance when the diver 800 swims, and at the same time, it is more closely attached to the face under the action of water pressure.

[0143] Without limitation, the housing 510 can be made of silicone material. The silicone material is relatively soft and has good elasticity, which is more convenient for the assembly of the housing 510 and the fixing bracket 520.

[0144] The mouthpiece 521 and the fixing bracket 520 can be of a split structure. At this time, the mouthpiece 521 can be fixed on the fixing bracket 520 by means of welding, bonding, clamping or threaded connection, etc. Or, the mouthpiece 521 and the fixing bracket 520 are of an integral structure, and the fixing bracket 520 and the mouthpiece 521 can be made by integral forming methods such as injection molding or machining.

[0145] In actual application, the mouthpiece 521 and the mouthpiece sleeve 530 both extend into the diver 800's oral cavity. In order to ensure that the breathing mouth mask 500 does not easily separate from the diver 800's face, the mouthpiece 521 needs to have a certain supporting effect on the diver 800's oral cavity, while the mouthpiece sleeve 530 only needs to isolate the mouthpiece 521 and the oral cavity. Therefore, relatively speaking, there is no special requirement for the rigidity of the mouthpiece sleeve 530. The mouthpiece sleeve 530 can be made of a flexible and / or elastic waterproof material, such as silicone. The mouthpiece sleeve 530 made of this material is convenient to carry and occupies little space when stored.

[0146] Without limitation, there are at least two mouthpieces 521, and the number of mouthpiece sleeves 530 is the same as the number of mouthpieces 521. Each mouthpiece 521 is sleeved with a mouthpiece sleeve 530.

[0147] In an embodiment of the present invention, by sleeving a mouthpiece cover 530 on the mouthpiece 521, the oral cavity of the diver 800 using the breathing mouth mask 500 contacts the mouthpiece cover 530 instead of directly contacting the mouthpiece 521. When different divers 800 share the same breathing mouth mask 500 or the mouthpiece cover 530 is contaminated, the mouthpiece cover 530 can be detached from the mouthpiece 521 and replaced, improving the hygiene problem during the use of the breathing mouth mask 500. Moreover, by replacing the mouthpiece cover 530 instead of the entire mouthpiece 521, it is also beneficial for cost savings.

[0148] In other alternative embodiments, the mouthpiece cover 530 has a receiving cavity 532 and an opening 531 communicating with the receiving cavity 532. The mouthpiece 521 passes through the opening 531 and is at least partially located within the receiving cavity 532.

[0149] The mouthpiece cover 530 is a hollow member. As Figure 10 and Figure 11 shown, one end of the mouthpiece cover 130 has an opening 531, facilitating the installation of the mouthpiece cover 530 on the mouthpiece 521. The other end of the mouthpiece cover 530 is closed, ensuring the coverage of the mouthpiece 521 by the mouthpiece cover 530 and further preventing the contact between the mouthpiece 521 and the oral cavity.

[0150] In other alternative embodiments, the mouthpiece cover 530 further has a limiting hole 533 communicating with the receiving cavity 532. The limiting hole 533 and the opening 531 are located on different surfaces of the mouthpiece cover 530; the mouthpiece 521 includes a support portion 5211 and a first limiting portion 5212. The support portion 5211 is fixed on the fixing frame 520 and is located within the receiving cavity 532; the first limiting portion 5212 is connected to the support portion 5211 and can pass through the limiting hole 533 to limit the detachment of the mouthpiece cover 530 from the support portion 5211.

[0151] The cooperation between the limiting hole 533 and the first limiting portion 5212 further strengthens the connection between the mouthpiece cover 530 and the mouthpiece 521, restricting the detachment of the mouthpiece cover 530 from the mouthpiece 521.

[0152] Non - restrictively, as Figure 10 and Figure 12 shown, the first limiting portion 5212 can be a cylindrical protrusion or a hook substantially in an L - shape.

[0153] In some embodiments, the distance between the first limiting portion 5212 and the end of the mouthpiece cover 530 near the fixing frame 520 is less than the distance between the first limiting portion 5212 and the end of the mouthpiece cover 530 far from the fixing frame 520. As Figure 10As shown, in practical applications, the mouthpiece 530 extends into the oral cavity, and the first limiting portion 5212 is arranged at the free end away from the bite piece 521, which can reduce or even avoid the contact between the first limiting portion 5212 exposed outside the mouthpiece 530 and the oral cavity, further ensuring the hygiene of the breathing mouth mask 500.

[0154] In other alternative embodiments, the bite piece 521 further includes a second limiting portion 5213. The second limiting portion 5213 is located at the end of the supporting portion 5211 away from the fixing bracket 520, and the first limiting portion 5212 is located between the second limiting portion 5213 and the fixing bracket 520; the cross-sectional area of the second limiting portion 5213 is larger than the cross-sectional area of the supporting portion 5211, restricting the bite piece 521 from detaching from the oral cavity of the diver 800.

[0155] In practical applications, the cross-sectional area of the second limiting portion 5213 is larger than the cross-sectional area of the supporting portion 5211, and the second limiting portion 5213 is less likely to detach from the oral cavity, further strengthening the connection between the bite piece 521 and the oral cavity, and further ensuring the fitting degree between the breathing mouth mask 500 and the face of the diver 800.

[0156] In other alternative embodiments, the mouthpiece 530 further has an avoidance hole 534. The avoidance hole 534 communicates with the accommodation cavity 532 and is distributed at intervals with the opening 531; the avoidance hole 534 is distributed along the setting direction of the bite piece 521.

[0157] In practical applications, after the avoidance hole 534 is provided, the avoidance hole 534 can be expanded, and it is easier to detach the mouthpiece 530 from the bite piece 521 or install the mouthpiece 530 by means of the avoidance hole 534.

[0158] As Figure 10 shown, the setting direction of the avoidance hole 534 is substantially the same as the setting direction of the supporting portion 5211 of the bite piece 521. Without limitation, the avoidance hole 534 is a long strip hole.

[0159] In some embodiments, the shape of the mouthpiece 530 is substantially the same as that of the bite piece 521. As Figures 10 to 12 shown, the mouthpiece 530 and the bite piece 521 with substantially the same shape can fit better.

[0160] As Figure 10 、 Figure 12 shown, the bite piece 521 is a toothed member. The toothed member occupies less space in the oral cavity and can facilitate the diver 800 to speak on the premise of facilitating biting. The supporting portion 5211 and the second limiting portion 5213 of the bite piece 521 are substantially perpendicular to each other. As Figure 11As shown, the mouthpiece 530 is composed of a horizontal section 535 and a vertical section 536. A long strip-shaped relief hole (i.e., the avoidance hole 534) is provided in the middle of the vertical section 536, and the long strip-shaped relief hole extends to the horizontal section 535. The horizontal section 535 is sleeved on the support portion 5211, and the vertical section 536 is sleeved on the second limiting portion 5213. The setting of the long strip-shaped relief hole facilitates the disassembly and assembly of the mouthpiece 530. To prevent the mouthpiece 530 from slipping off during use, an L-shaped hook extends outward from the outer side wall of the support portion 5211, and a square hole is provided on the side wall of the horizontal section 535 of the mouthpiece 530, and the square hole is adapted to the L-shaped hook.

[0161] In other alternative embodiments, the breathing mouth mask 500 further includes a switch member 580, and the switch member 580 is electrically connected to the microphone module 190; the switch member 580 is used to turn on or off the call function of the microphone module 190.

[0162] The microphone module 190 is used to collect the second audio signal generated by the diver 800's speech.

[0163] The switch member 580 can be a button. When the diver 800 needs to communicate, the button can be pressed, and the microphone module 190 works, and the received audio is transmitted to the underwater communication device through the voice cable 700. When the diving operation is over, the mouthpiece 530 is removed, and the mouthpiece 521 is cleaned. A brand-new mouthpiece 530 can be replaced for the next use to ensure the cleanliness and hygiene when used by different people.

[0164] By electrically connecting the switch member 580 to the microphone module 190, the call function of the microphone module 190 can be controlled, improving the timeliness of communication.

[0165] Without limitation, the voice cable 700 can be a waterproof cable, also known as a watertight cable.

[0166] In other alternative embodiments, the breathing mouth mask 500 further includes a first fixing base 572 and a second fixing base 571. The first fixing base 572 is installed on the fixing frame 520; the second fixing base 571 covers the first fixing base 572 and jointly forms a sealed cavity with the first fixing base 572, and the sealed cavity houses the microphone module 190, at least part of the voice cable 700, and at least part of the switch member 580.

[0167] Such as Figure 13As shown, the microphone module 190, a part of the voice cable 700 connected to the microphone module 190, and the switch 580 are all connected to the fixing bracket 520 through the first fixing seat 572. By integrating the microphone module 190, a part of the voice cable 700, and the switch 580 in a sealed cavity, it is convenient for sealed installation, effectively preventing water outside the sealed cavity from entering the sealed cavity and contacting the microphone module 190, a part of the voice cable 700, and the switch 580 when diving, and effectively protecting the communication function of the breathing mouthpiece 500.

[0168] Without limitation, a sealing ring can be arranged between the first fixing seat 572 and the second fixing seat 571, so that a sealed cavity is formed after the first fixing seat 572 and the second fixing seat 571 are covered.

[0169] In some embodiments, an installation groove 573 is formed on the first fixing seat 572. The installation groove 573 is a part of the sealed cavity. The microphone module 190, a part of the voice cable 700, and the switch 580 are all installed in the installation groove 573, and sealing elements are arranged in the assembly gaps between the microphone module 190, a part of the voice cable 700, and the switch 580 and the first fixing seat 572. The sealing elements include but are not limited to silica gel. The sealing elements not only further ensure the sealing performance of each assembly gap, but also help to strengthen the connection strength between the microphone assembly and the first fixing seat 572, the connection effect between the microphone assembly and the first fixing seat 572, and the connection strength between the switch 580 and the first fixing seat 572.

[0170] In other alternative embodiments, the breathing mouthpiece 500 further includes ear hooks 560 and a fixing strap. The ear hooks 560 are fixed on the housing 510 and form an installation hole 561 with the housing 510. Two ends of the fixing strap are respectively fixed on the fixing bracket 520 through the installation hole 561.

[0171] The installation hole 561 is used to realize the connection between the fixing strap and the housing 510. The fixing strap is used to fix the breathing mouthpiece 500 on the head of the diver 800, improving the tightness of the fit between the breathing mouthpiece 500 and the face, and facilitating the wearing of the breathing mouthpiece 500.

[0172] The number of the installation holes 561 is at least two. Figure 8 and Figure 9 Exemplarily, the housing 510 with two installation holes 561 is shown.

[0173] In practical applications, the ear hook 560 and the housing 510 are used together to form the mounting hole 561, rather than forming the mounting hole 561 by opening on the housing 510, which is beneficial to ensuring the sealing performance of the housing 510. The mounting hole 561 is located on the housing 510 at a position adjacent to the ear of the diver 800. When worn, the head of the diver 800 is located between the fixing strap and the housing 510. The two ends of the fixing strap respectively pass through the mounting holes 561 at two different positions. After the fixing strap is fixed to the housing 510, the diver 800 can adjust the fixing strength of the fixing strap by changing the length of the fixing strap.

[0174] In some embodiments, the fixing strap is of an integral structure, and the two ends of the fixing strap respectively pass through the mounting holes 561 at different positions; alternatively, the fixing strap is of a split structure, that is, the fixing strap includes a first fixing strap and a second fixing strap. While the first fixing strap and the second fixing strap are connected by a joint, the first fixing strap and the second fixing strap are also connected to the mounting holes 561 at different positions. When removing the breathing mask from the head of the diver 800, the elasticity of the fixing strap can be utilized to increase the distance between the fixing strap and the housing 510, or the locking of the first fixing strap and the second fixing strap by the connector can be released to achieve disassembly. The connector can be a snap-type quick-release connector.

[0175] In other alternative embodiments, the breathing mouthpiece 500 further includes: a sealing strip 550, which is fixed on the fixing frame 520 and distributed along the circumference of the air outlet 512.

[0176] As Figure 8 and Figure 9 shown, the sealing strip 550 is used to seal the gap between the housing 510 and the face of the diver 800, so as to prevent water from entering the interior of the housing 510 through the gap between the housing 510 and the face of the diver 800.

[0177] In other alternative embodiments, the earphone includes a base 10, a cover 20, a magnetic core 30 and a driving circuit (not shown). The cover 20 covers the base 10, and the cover 20 and the base 10 together form a sealed cavity 11; the magnetic core 30 is located in the sealed cavity 11; the driving circuit is respectively electrically connected to the magnetic core and the voice cable, and drives the magnetic core to vibrate by changing the electrical signal passing through the magnetic core, and drives the cover to resonate to generate the first audio signal.

[0178] The driving circuit drives the magnetic core 30 to vibrate, and the magnetic core 30 drives the cover 20 to resonate and emit sound. Compared with piezoelectric ceramic earphones, the sound quality output by the earphone in the embodiment of the present invention is less affected by the vibration source magnetic core 30, but is related to the cover 20. This resonance sound-emitting method can effectively improve the problem of sharp sound.

[0179] Moreover, compared with the driving circuit of a piezoelectric ceramic earphone, the driving circuit of the earphone in the embodiment of the present invention can be simpler and have a lower cost.

[0180] By selecting the cover 20 made of different materials, sounds with different qualities can be output, and a sound quality with good high-frequency, medium-frequency or low-frequency response can be obtained. For example, when the material of the cover 20 is wood, a deep sound quality with good low frequency can be output. When the material of the cover 20 is beryllium copper alloy, a sound quality with prominent high frequency can be obtained. And when the material of the cover 20 is glass, a clear and ethereal sound quality can be obtained, and the sound frequency is between that of the cover 20 made of wood and beryllium copper alloy. It can be understood that the material of the red cover 20 in the embodiment of the present invention is not limited to the above several types, and can also be other materials such as plastic and cast iron.

[0181] In some embodiments, the magnetic core 30 includes: a magnetostrictive body and a coil wound around the magnetostrictive body. After an alternating current is passed through the coil, an alternating magnetic field is generated, and under the action of the alternating magnetic field, the magnetostrictive body generates elongation and shortening changes, that is, vibration is generated. The magnetostrictive body is generally a metal material. For example, the material of the magnetostrictive body includes but is not limited to metals such as iron, cobalt, nickel and their alloys.

[0182] Non-limitingly, the driving circuit can also be located in the sealed cavity 11. The driving circuit can realize the vibration of the magnetostrictive body by changing parameters of electrical signals such as the current intensity, current direction, and frequency of the alternating current passing through the coil.

[0183] By replacing the magnetic core 30 with different powers, or by controlling the circuit to change the current intensity passing through the magnetic core 30 and other methods, the loudness of the sound output by the earphone can be made different to meet the requirements of different scenarios. For example, the loudness of the output sound can be increased by increasing the power of the magnetic core 30; conversely, the loudness of the output sound can be reduced by reducing the power of the magnetic core 30.

[0184] By selecting the cover 20 and the base 10 with different thickness dimensions, the earphone can meet the requirements of different pressure resistance strengths. Generally, for the same material, the greater the thickness, the more pressure-resistant the earphone is, and the deeper the diving depth it can adapt to.

[0185] The sealed cavity 11 can prevent the liquid in the external environment where the earphone is located from entering, and has a protective effect on the magnetic core 30.

[0186] In the embodiment of the present invention, the sealed cavity 11 formed by the cover 20 and the base 10 together ensures the waterproof effect and pressure resistance effect of the earphone when used underwater.

[0187] In some other alternative embodiments, the earphone further includes: a shock pad 60, located between the magnetic core 30 and the base 10.

[0188] Such as Figure 14As shown, the shock pad 60 can reduce the transmission of vibrations generated by the magnetic core 30 to the base 10, ensure that the vibrations are transmitted towards the cover 20, improve the directivity of sound transmission, and is conducive to improving the privacy of the earphone.

[0189] The material of the shock pad 60 includes but is not limited to rubber or foam.

[0190] In practical applications, the shock pad 60 fills the gap between the magnetic core 30 and the base 10, and also has a fixing effect on the magnetic core 30, reducing or even avoiding the shaking of the magnetic core 30 in the sealing cavity 11.

[0191] In some other alternative embodiments, the cover 20 and the base 10 are adhesively connected or welded at the joint.

[0192] By using the method of adhesion or welding, not only can the cover 20 be fixed on the base 10, but also the gap between the cover 20 and the base 10 can be sealed to ensure the sealing performance of the sealing cavity 11.

[0193] In some embodiments, the earphone further includes a sealing ring (not shown), which is located between the cover 20 and the base 10 to seal the gap between the cover 20 and the base 10. The sealing ring can further ensure the airtight and waterproof effect of the sealing cavity 11.

[0194] The adhesive includes but is not limited to epoxy resin glue or acrylic ester glue.

[0195] Without limitation, the welding can use ultra-high frequency welding technology.

[0196] In some other alternative embodiments, the magnetic core 30 is adhesively connected to the cover 20.

[0197] Adhesively connecting the magnetic core 30 to the cover 20 is not only beneficial to stabilizing the magnetic core 30, but also beneficial to the magnetic core 30 driving the cover 20 to vibrate, further improving the sound production effect.

[0198] The adhesive connection between the magnetic core 30 and the cover 20 can be achieved by using an adhesive or an adhesive tape.

[0199] In some other alternative embodiments, the earphone further includes: a connector 50; the voice cable 700 passes through the base 10 and is electrically connected to the drive circuit; the connector 50 forms a liquid-tight structure at the part where the voice cable 700 passes through the base 10.

[0200] In practical applications, part of the voice cable 700 can be electrically connected to the communication module in the diving device, and the communication module converts the received information into an audio electrical signal and transmits it to the magnetic core 30 through part of the voice cable 700.

[0201] Such as Figures 14 to 17As shown, a part of the voice cable 700 passes through the connector 50, and a part of the voice cable 700 extends at least outside the sealing cavity 11 for electrical connection with the communication module. The connector 50 is used to seal the gap formed when a part of the voice cable 700 passes through the base 10 to ensure the sealing performance of the sealing cavity 11. In addition, the connector 50 is located at the connection between a part of the voice cable 700 and the base 10, which has a supporting effect on a part of the voice cable 700 and reduces the risk of bending damage to a part of the voice cable 700 at the connection with the base 10.

[0202] In some other alternative embodiments, the connector 50 forms the liquid-tight structure by bonding or welding with the base 10.

[0203] The adhesive includes, but is not limited to, epoxy resin glue or acrylic ester glue.

[0204] Without limitation, the welding can use ultra-high frequency welding technology.

[0205] To further ensure the sealing effect, the earphone further includes a seal (not shown). A seal is provided at the connection between the connector 50 and the base 10, and / or at the connection between the connector 50 and the voice cable 700. The seal can be an elastic rubber part.

[0206] In some other alternative embodiments, as Figures 15 to 17 shown, the earphone further includes: a hanger 70. One end of the hanger 70 has a receiving groove 72, and the receiving groove 72 at least houses the base 10. The other two ends of the hanger 70 include hooks 71.

[0207] The hanger 70 has a fixed connection function, which is convenient for wearing the earphone.

[0208] In some embodiments, the base 10 and the receiving groove 72 are in interference fit. The interference fit ensures the reliability of the connection between the base 10 and the hanger 70 and facilitates the disassembly of the hanger 70.

[0209] In some embodiments, as Figure 15 and Figure 16 shown, the cover 20 is exposed outside the receiving groove 72. In practical applications, the cover 20 faces the human ear, and sound is received through the cover 20. The cover 20 exposed outside the receiving groove 72 reduces the cover 20 being covered by the hanger 70 and ensures the sound transmission effect.

[0210] The hanger 70 can be installed or not according to needs. When the diver wears a diving hood, the hanger 70 can be omitted, and the earphone as Figure 14 shown can be directly inserted into the hood. When the diver does not wear a diving hood, the hanger 70 is needed. The hanger 70 can be installed on the diver's face mask by using the hooks 71 to fix the earphone.

[0211] In some other alternative embodiments, the second end of the hanger 70 is bent to form the hook 71.

[0212] The hook 71 formed by bending has a simple structure and is convenient to connect.

[0213] In some other alternative embodiments, the wall of the accommodating groove 72 formed by the hanger 70 has an avoidance opening 73.

[0214] As Figure 17 shown, the avoidance opening 73 is used to avoid the voice cable 700, so that the voice cable 700 does not need to be bent when passing through the hanger 70, which is beneficial to ensuring the service life of the voice cable 700.

[0215] In a specific example, as Figures 1 to 17 shown, the communication module 300 is installed on the gas cylinder 400 containing compressed air through the installation structure 900. Installing the communication module 300 on the gas cylinder 400 can prevent the communication module 300 from being blocked and improve the efficiency and quality of wireless signal transmission and reception. The voice cable 700 is clamped on the air pipe 410 through a buckle. The earphone 600 includes a hanger 70. When the diver 800 uses the diving headgear, the earphone 600 can be directly inserted into the headgear. When not using the diving headgear, the earphone 600 is hung on the diving goggles through the hanger 70. The breathing mouthpiece 500 includes a silica gel hanging strap (also known as a fixing strap). When not using the breathing mouthpiece 500, the breathing mouthpiece 500 is suspended in front of the chest through the silica gel hanging strap. The breathing mouthpiece 500 includes a mechanical button (i.e., the switch 580), and the mechanical button has a waterproof and pressure-resistant structure. By pressing the mechanical button in different ways, the diver can realize information interaction with the underwater communication module 300. In this example, the diving device has the advantages of good communication performance, quick disassembly and assembly, reduced safety hazards, clear sound collection of the microphone module 190, and full audio of the earphone 600. Moreover, the communication module 300 in the embodiment of the present invention reduces the possibility of being blocked and has good signal transmission quality; using the toothed mouthpiece 530 makes pronunciation and sound collection clearer.

[0216] The features disclosed in the several product embodiments provided by the present invention can be arbitrarily combined without conflict to obtain new product embodiments.

[0217] Other structures and operations of the products according to the embodiments of the present invention are understandable and easy to implement for those skilled in the art, and therefore will not be described in detail.

[0218] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
