[0064] The accompanying drawings are included to provide a further understanding of the application and are incorporated in and constitute a part of this specification, illustrate embodiments of the application and together with the description serve to explain the principles of the application. In the drawings: Figures 1 to 3A breathing mouthpiece is shown according to a preferred embodiment of the present application, wherein the breathing mouthpiece comprises a housing 10 and a microphone device 20 arranged at the housing 10, the housing 10 covers the mouth of a user when the breathing mouthpiece is worn by the diver, and the microphone device 20 is held in front of the mouth of the diver, so that the sound waves emitted by the diver when the diver speaks can be collected by the microphone device 20 for enabling communication between the diver and other people.

[0065] In particular, the housing 10 has a breathing space 11 and an air inlet 12 and a breathing port 13 respectively connected to the breathing space 11, the breathing port 13 defines a wearing side 14 of the housing 10, and the air inlet 12 of the housing 10 is arranged to be able to connect to an air tank to supplement the air in the breathing space 11 of the housing 10 through the air inlet 12 of the housing 10 for the diver to breathe. When the diver wears the breathing mouthpiece, the wearing side 14 of the housing 10 is fitted to the face of the diver and closes the breathing port 13 of the housing 10 by the face of the diver. In order to ensure that the face of the diver can close the breathing port 13 of the housing 10 when the diver wears the breathing mouthpiece, on the one hand, the wearing side 14 of the housing 10 is designed to be arc-shaped to fit the curvature of the face, and on the other hand, the wearing side 14 of the housing 10 is deformable, so that the shape of the wearing side 14 of the housing 10 can be automatically fine-tuned based on the curvature of the face of the diver, so that when the diver wears the breathing mouthpiece to dive, the water cup prevents water from entering the breathing space 11 of the housing 10 between the housing 10 and the face of the diver.

[0066] Preferably, the housing 10 is made of a flexible material as a whole, for example, the housing 10 can be made of a silica gel material, so that the wearing side 14 of the housing 10 is deformable, so that when the diver wears the breathing mouthpiece, the shape of the wearing side 14 of the housing 10 can be automatically fine-tuned based on the curvature of the face of the diver to allow the face of the diver to close the breathing port 13 of the housing 10.

[0067] With reference to the accompanying drawings Figures 1 to 3 The breathing mouthpiece further comprises a holding device 30, wherein the holding device 30 is arranged at the housing 10, and the main part of the holding device 30 is located in the breathing space 11 of the housing 10, and the mouthpiece part of the holding device 30 protrudes from the wearing side 14 of the housing 10, and the diver can wear the breathing mouthpiece by biting the mouthpiece part of the holding device 30.

[0068] With reference to the accompanying drawings Figures 4 to 8One specific example of the microphone device 20 of the breathing mask of the present application is shown in conjunction with the accompanying drawings Figures 1 to 3 The microphone device 20 comprises an assembling unit 21, a microphone 22 and a waterproof sound-permeable membrane 23. The assembling unit 21 comprises an assembling body 211 and a first assembling arm 212 integrally extending outwardly from the assembling body 211, the first assembling arm 212 having an assembling cavity 2121 and an assembling opening 2122 communicating with the assembling cavity 2121, the assembling opening 2122 of the first assembling arm 212 defining an opening end 2120 of the first assembling arm 212. The microphone 22 has a receiving face 221, the microphone 22 being assembled in the assembling cavity 2121 of the first assembling arm 212 from the assembling opening 2122 of the first assembling arm 212, and the receiving face 221 of the microphone 22 facing the assembling opening 2122 of the first assembling arm 212. The waterproof sound-permeable membrane 23 is arranged on the first assembling arm 212, and the waterproof sound-permeable membrane 23 closes the assembling opening 2122 of the first assembling arm 212, so that the microphone 22 is kept in a waterproof space 200 to avoid water directly contacting the microphone 22, thereby ensuring the reliability of the microphone 22. In other words, the waterproof sound-permeable membrane 23 and the first assembling arm 212 of the assembling unit 21 form the waterproof space 200, and the microphone 22 is arranged in the waterproof space 200 to avoid water directly contacting the microphone 22.

[0069] The first assembling arm 212 of the assembling unit 21 of the microphone device 20 is kept in the breathing space 11 of the shell 10 to arrange the microphone device 20 in the shell 10.

[0070] It is worth mentioning that the specific way of keeping the first assembling arm 212 of the assembling unit 21 in the breathing space 11 of the shell 10 is not limited in the breathing mask of the present application. For example, in this specific example of the breathing mask of the present application, referring to the accompanying drawings Figure 3 The inner wall of the shell 10 for forming the breathing space 11 further has a clamping groove 15, and the assembling body 211 of the assembling unit 21 is clamped in the clamping groove 15 of the shell 10 to keep the first assembling arm 212 of the assembling unit 21 in the breathing space 11 of the shell 10.

[0071] Continuing to refer to the accompanying drawings Figure 3, the housing 10 has a switch through-hole 16 communicating with the breathing space 11, wherein the assembly unit 21 further comprises a second assembly arm 213 integrally extending outwardly from the assembly body 211, and a distal end of the second assembly arm 213 extends from the breathing space 11 of the housing 10 to the outside through the switch through-hole 16 of the housing 10, so that the microphone device 20 is reliably arranged in the housing 10.

[0072] Preferably, the housing 10 has a cable through-hole 17 communicating with the breathing space 11, wherein the assembly unit 21 further comprises a third assembly arm 214 integrally extending outwardly from the assembly body 211, and a distal end of the third assembly arm 214 extends from the breathing space 11 of the housing 10 to the outside through the cable through-hole 17 of the housing 10, so that the microphone device 20 is reliably arranged in the housing 10.

[0073] In other words, by clamping the assembly body 211 of the assembly unit 21 in the clamping groove 15 of the housing 10, the distal end of the second assembly arm 213 is allowed to extend from the breathing space 11 of the housing 10 to the outside through the switch through-hole 16 of the housing 10, and the distal end of the third assembly arm 214 is allowed to extend from the breathing space 11 of the housing 10 to the outside through the cable through-hole 17 of the housing 10, so that the microphone device 20 can be reliably arranged in the housing 10, and the first assembly arm 212 of the assembly unit 21 is reliably retained in the breathing space 11 of the housing 10.

[0074] Further, the assembly body 211 of the assembly unit 21 has a receiving space 2111, and the assembly cavity 2121 of the first assembly arm 212 communicates with the receiving space 2111 of the assembly body 211, wherein the third assembly arm 214 has a cable passage 2141 communicating with the receiving space 2111 of the assembly body 211. The microphone device 20 further comprises a circuit board 24 and a connection cable 25, the circuit board 24 is received in the receiving space 2111 of the assembly body 211, the microphone 22 is connected to the circuit board 24, one end of the connection cable 25 extends to the receiving space 2111 of the assembly body 211 through the cable passage 2141 of the third assembly arm 214, and is connected to the circuit board 24, and the other end of the connection cable 25 is located outside the housing 10.

[0075] In addition, the microphone device 20 further comprises a magnetic switch 26, which is operably installed on the second assembly arm 213 of the assembly unit 21 and connected to the circuit board 24, and the magnetic switch 26 protrudes from the shell 10, wherein when the diver wears the breathing mouthpiece, the diver can operate the magnetic switch 26 by pressing.

[0076] In the breathing mouthpiece of the present application, the microphone 22 is assembled in the assembly cavity 2121 of the first assembly arm 212 of the assembly unit 21 with the receiving surface 221 of the microphone 22 facing the assembly opening 2122 of the first assembly arm 212, and the waterproof sound-permeable film 23 is arranged on the first assembly arm 212 in a manner of closing the assembly opening 2122 of the first assembly arm 212, so as to keep the microphone 22 in the waterproof space and avoid direct contact of water with the microphone 22. Since the first assembly arm 212 of the assembly unit 21 of the microphone device 20 is kept in the breathing space 11 of the shell 10, when the diver wears the breathing mouthpiece, if the diver starts to speak, the sound wave emitted by the diver can reach the microphone 22 after passing through the waterproof sound-permeable film 23, so as to allow the microphone 22 to receive sound, thereby realizing communication between the diver and others. That is, the waterproof sound-permeable film 23 has the ability to prevent water from passing through and allow sound waves to pass through.

[0077] Reference is made to the accompanying drawings Figures 6 to 8 The microphone device 20 comprises a set ring 27, the waterproof sound-permeable film 23 comprises a film body center portion 231 and a film body edge portion 232 surrounding the film body center portion 231, the film body center portion 231 blocks the assembly opening 2122 of the first assembly arm 212 of the assembly unit 21, and the film body edge portion 232 surrounds the opening end 2120 of the first assembly arm 212, wherein the set ring 27 is set on the opening end 2120 of the first assembly arm 212 of the assembly unit 21, and the film body edge portion 232 of the waterproof sound-permeable film 23 is clamped between the set ring 27 and the first assembly arm 212 of the assembly unit 21, so as to reliably arrange the waterproof sound-permeable film 23 on the first assembly arm 212 of the assembly unit 21.

[0078] That is, after the sleeve ring 27 is sleeved on the open end 2120 of the first assembly arm 212 of the assembly unit 21, a clamping force can be provided between the sleeve ring 27 and the first assembly arm 212 of the assembly unit 21 for clamping the membrane edge portion 232 of the waterproof sound permeable membrane 23, so that the membrane center portion 231 of the waterproof sound permeable membrane 23 is kept in a position shielding the assembly opening 2122 of the first assembly arm 212, and thus the waterproof sound permeable membrane 23 can reliably seal the assembly opening 2122 of the first assembly arm 212 to keep the microphone 22 in the waterproof space 200.

[0079] It can be understood that the shape of the inner wall of the sleeve ring 27 matches the shape of the outer wall of the first assembly arm 212 of the assembly unit 21, so that the sleeve ring 27 and the first assembly arm 212 can provide a clamping force in the entire circumferential direction of the membrane edge portion 232 of the waterproof sound permeable membrane 23 to ensure that the waterproof sound permeable membrane 23 can reliably seal the assembly opening 2122 of the first assembly arm 212 for keeping the microphone 22 in the waterproof space. For example, in this specific example of the breathing mask of the present application, the sleeve ring 27 is a circular ring body, and the first assembly arm 212 of the assembly unit 21 is a circular cylinder, so that the shape of the inner wall of the sleeve ring 27 matches the shape of the outer wall of the first assembly arm 212 of the assembly unit 21.

[0080] Preferably, the inner diameter of the sleeve ring 27 is larger than the outer diameter of the first assembly arm 212 of the assembly unit 21, and the inner diameter of the sleeve ring 27 is smaller than the sum of the outer diameter of the first assembly arm 212 and twice the thickness of the membrane edge portion 232 of the waterproof sound permeable membrane 23, so that after the sleeve ring 27 is sleeved on the open end 2120 of the first assembly arm 212 of the assembly unit 21, a clamping force can be provided between the sleeve ring 27 and the first assembly arm 212 for clamping the membrane edge portion 232 of the waterproof sound permeable membrane 23 to prevent the waterproof sound permeable membrane 23 from falling off the first assembly arm 212.

[0081] Preferably, after the membrane body central portion 231 of the waterproof sound permeable membrane 23 blocks the assembly opening 2122 of the first assembly arm 212 of the assembly unit 21 and the membrane body edge portion 232 surrounds the opening end 2120 of the first assembly arm 212, the sleeve ring 27 is pushed to the position of the opening end 2120 of the first assembly arm 212 to avoid the sleeve ring 27 applying force in the circumferential direction to the waterproof sound permeable membrane 23, i.e. during the process of sleeving the sleeve ring 27 to the position of the opening end 2120 of the first assembly arm 212, the sleeve ring 27 is prevented from rotating relative to the first assembly arm 212, thus avoiding the sleeve ring 27 applying force in the circumferential direction to the waterproof sound permeable membrane 23. In this way, on the one hand, the problem of the waterproof sound permeable membrane 23 being torn and even broken is avoided, which is crucial for improving the yield of the microphone device 20; on the other hand, during the process of pushing the sleeve ring 27 to sleeve to the position of the opening end 2120 of the first assembly arm 212 of the assembly unit 21, the sleeve ring 27 pulls the membrane body edge portion 232 of the waterproof sound permeable membrane 23 in the direction away from the opening end 2120 of the first assembly arm 212, so that the membrane body central portion 231 of the waterproof sound permeable membrane 23 can be kept in a taut state to ensure the sound receiving effect of the microphone device 20.

[0082] After the sleeve ring 27 is sleeved to the position of the opening end 2120 of the first assembly arm 212 of the assembly unit 21, glue is applied between the sleeve ring 27 and the first assembly arm 212 to allow the glue to bond the sleeve ring 27 and the first assembly arm 212, so that not only the sleeve ring 27 can be prevented from falling off the first assembly arm 212, but also the water tightness between the sleeve ring 27 and the first assembly arm 212 is increased, thus ensuring the reliability of the microphone device 20. In the specific example of the microphone device 20 shown in the drawings, the membrane body edge portion 232 of the waterproof sound permeable membrane 23 extends to the middle portion of the sleeve ring 27, so that the sleeve ring 27 and the first assembly arm 212 have a gap therebetween, and the glue applied between the sleeve ring 27 and the first assembly arm 212 is hidden in the gap to avoid the glue used to bond the sleeve ring 27 and the first assembly arm 212 from protruding outward. In addition, after the sleeve ring 27 is sleeved to the position of the opening end 2120 of the first assembly arm 212 of the assembly unit 21, glue can also be applied between the sleeve ring 27 and the waterproof sound permeable membrane 23 to allow the glue to bond the sleeve ring 27 and the waterproof sound permeable membrane 23. Figures 4 to 8 In the specific example of the microphone device 20 shown in the drawings, the membrane body edge portion 232 of the waterproof sound permeable membrane 23 extends to the middle portion of the sleeve ring 27, so that the sleeve ring 27 and the first assembly arm 212 have a gap therebetween, and the glue applied between the sleeve ring 27 and the first assembly arm 212 is hidden in the gap to avoid the glue used to bond the sleeve ring 27 and the first assembly arm 212 from protruding outward. In addition, after the sleeve ring 27 is sleeved to the position of the opening end 2120 of the first assembly arm 212 of the assembly unit 21, glue can also be applied between the sleeve ring 27 and the waterproof sound permeable membrane 23 to allow the glue to bond the sleeve ring 27 and the waterproof sound permeable membrane 23.

Figure 9 In this specific example of the microphone device 20 shown in FIG. 12, the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' extends to the rear side of the sleeve ring 27, so that before the sleeve ring 27 is sleeved to the opening end 2120 of the first assembly arm 212 of the assembly unit 21, the membrane center portion 231 can be kept in a taut state by pressing the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' toward the opening end 2120 of the first assembly arm 212, or by pulling the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' away from the opening end 2120 of the first assembly arm 212, and after the sleeve ring 27 is sleeved to the opening end 2120 of the first assembly arm 212 of the assembly unit 21, the sleeve ring 27 and the first assembly arm 212 can cooperate with each other to keep the membrane center portion 231 of the waterproof sound-transmissive membrane 23' in a taut state, so as to ensure the sound pickup effect of the microphone device 20.

[0084] That is, the microphone device 20 shown in FIG. 12 is different from the microphone device 20 shown in FIG. 11 in that the waterproof sound-transmissive membrane 23' is used instead of the waterproof sound-transmissive membrane 23. Figures 4 to 8 The microphone device 20 shown in FIG. 12 is different from the microphone device 20 shown in FIG. 11 in that the waterproof sound-transmissive membrane 23' is used instead of the waterproof sound-transmissive membrane 23. Figure 9 In this specific example of the microphone device 20 shown in FIG. 12, the waterproof sound-transmissive membrane 23' is used instead of the waterproof sound-transmissive membrane 23, and the size of the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' is increased, so that before the sleeve ring 27 is sleeved, the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' can be forced, for example, the membrane edge portion 232 can be pressed toward the opening end 2120 of the first assembly arm 212, or the membrane edge portion 232 can be pulled away from the opening end 2120 of the first assembly arm 212, so that the membrane center portion 231 is kept in a taut state, and during the sleeving of the sleeve ring 27, the membrane edge portion 232 of the waterproof sound-transmissive membrane 23' can be kept in a forced state, so as to ensure that after the sleeve ring 27 is sleeved to the opening end 2120 of the first assembly arm 212 of the assembly unit 21, the membrane center portion 231 of the waterproof sound-transmissive membrane 23' is kept in a taut state, thereby ensuring the sound pickup effect of the microphone device 20.

[0085] The microphone device 20 shown in FIG. 12 is different from the microphone device 20 shown in FIG. 11 in that the waterproof sound-transmissive membrane 23' is used instead of the waterproof sound-transmissive membrane 23.

Figures 4 to 8 The microphone device 20 shown in FIG. 12 is different from the microphone device 20 shown in FIG. 11 in that the waterproof sound-transmissive membrane 23' is used instead of the waterproof sound-transmissive membrane 23. Figure 10In this specific example of the microphone device 20 shown, after the sleeve ring 27 is sleeved on the opening end 2120 of the first assembly arm 212 of the assembly unit 21 to clamp the membrane edge portion 232 of the waterproof sound-permeable membrane 23 between the sleeve ring 27 and the first assembly arm 212, a riveting portion 28 is formed for riveting the first assembly arm 212 of the assembly unit 21, the waterproof sound-permeable membrane 23 and the sleeve ring 27, so that the sleeve ring 27 can not fall off from the opening end 2120 of the first assembly arm 212, and the membrane central portion 231 of the waterproof sound-permeable membrane 23 can be kept in a taut state.

[0086] Specifically, the outer wall of the first assembly arm 212 has at least one glue filling groove 2123, the sleeve ring 27 has at least one glue filling hole 271, and the membrane edge portion 232 of the waterproof sound-permeable membrane 23 has at least one glue filling hole 2321. After the sleeve ring 27 is sleeved on the opening end 2120 of the first assembly arm 212 of the assembly unit 21 to clamp the membrane edge portion 232 of the waterproof sound-permeable membrane 23 between the sleeve ring 27 and the first assembly arm 212, the position of the glue filling hole 271 of the sleeve ring 27, the position of the glue filling hole 2321 of the membrane edge portion 232 and the position of the glue filling groove 2123 of the first assembly arm 212 correspond to each other, and glue is filled into the glue filling hole 271 of the sleeve ring 27, the glue filling hole 2321 of the membrane edge portion 232 and the glue filling groove 2123 of the first assembly arm 212 through the glue filling hole 271 of the sleeve ring 27 to form the riveting portion 28 for riveting the first assembly arm 212 of the assembly unit 21, the waterproof sound-permeable membrane 23 and the sleeve ring 27.

[0087] Preferably, the inner wall of the sleeve ring 27 has a ring-shaped glue distribution groove 272, the side wall of the sleeve ring 27 has a glue filling port 271 which is communicated with the glue distribution groove 272, the membrane body edge portion 232 of the waterproof sound permeable membrane 23 has a plurality of glue filling holes 2321, the first assembly arm 212 has a plurality of glue filling grooves 2123, the positions of the glue filling holes 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 and the positions of the glue filling grooves 2123 of the first assembly arm 212 correspond to the position of the glue distribution groove 272 of the sleeve ring 27, the glue filled into the glue filling port 271 of the sleeve ring 27 is distributed to the glue filling holes 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 and the glue filling grooves 2123 of the first assembly arm 212 by the glue distribution groove 272 of the sleeve ring 27, so that the sleeve ring 27 can only have one glue filling port 271, which can not only simplify the glue filling process, but also ensure the appearance of the microphone device 20.

[0088] According to another aspect of the present application, the present application further provides a manufacturing method of the microphone device 20, wherein the manufacturing method comprises the following steps:

[0089] (a) assembling the microphone 22 to the assembly cavity 2121 of the first assembly arm 212 through the assembly opening 2122 of the first assembly arm 212, wherein the receiving surface 221 of the microphone 22 faces the assembly opening 2122 of the first assembly arm 212; and

[0090] (b) closing the assembly opening 2122 of the first assembly arm 212 by the waterproof sound permeable membrane 23 to obtain the microphone device 20. The waterproof sound permeable membrane 23 has the ability to prevent water from passing through and allow sound waves to pass through, so that when the diver wears the breathing mask configured with the microphone device 20 for diving, even if the breathing space 11 of the shell 10 is filled with water, water cannot enter the assembly cavity 2121 of the first assembly arm 212 through the waterproof sound permeable membrane 23, so as to prevent water from contacting the microphone 22 and ensure the reliability of the microphone device 20, if the diver starts to speak, the sound waves emitted by the diver can reach the microphone 22 after passing through the waterproof sound permeable membrane 23, so as to allow the microphone 22 to receive sound, for realizing the communication between the diver and others.

[0091] Further, the step (b) comprises the following steps: (b.1), allowing the membrane body center portion 231 of the waterproof sound permeable membrane 23 to shield the assembly opening 2122 of the first assembly arm 212; (b.2), allowing the membrane body edge portion 232 of the waterproof sound permeable membrane 23 to surround the opening end 2120 of the first assembly arm 212; (b.3), pushing the sleeving ring 27 to the position of sleeving the opening end 2120 of the first assembly arm 212, so as to clamp at least a part of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 between the sleeving ring 27 and the first assembly arm 212, thereby setting the waterproof sound permeable membrane 23 on the first assembly arm 212 to close the assembly opening 2122 of the first assembly arm 212 by the waterproof sound permeable membrane 23.

[0092] In the step (b.3), during the process of pushing the sleeving ring 27 to the position of sleeving the opening end 2120 of the first assembly arm 212, the rotation of the sleeving ring 27 relative to the first assembly arm 212 is prevented, so as to avoid the sleeving ring 27 applying a circumferential direction force to the waterproof sound permeable membrane 23, in this way, on the one hand, the waterproof sound permeable membrane 23 is prevented from being wrinkled or even torn, which is crucial for improving the yield of the microphone device 20, on the other hand, during the process of pushing the sleeving ring 27 to the position of sleeving the opening end 2120 of the first assembly arm 212, the sleeving ring 27 pulls the membrane body edge portion 232 of the waterproof sound permeable membrane 23 away from the opening end 2120 of the first assembly arm 212, in this way, the membrane body center portion 231 of the waterproof sound permeable membrane 23 can be kept in a taut state to ensure the sound receiving effect of the microphone device 20.

[0093] In some embodiments, after the step (b.2), the membrane body edge portion 232 of the waterproof sound permeable membrane 23 is pressed against the outer wall of the first assembly arm 212, so that the membrane body center portion 231 of the waterproof sound permeable membrane 23 is in a taut state, and in the step (b.3), the pressed state of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 is maintained, that is, during the process of sleeving the sleeving ring 27 to the position of sleeving the opening end 2120 of the first assembly arm 212, the membrane body edge portion 232 of the waterproof sound permeable membrane 23 is always pressed against the first assembly arm 212 to keep the membrane body center portion 231 in a taut state, in this way, after the sleeving ring 27 is sleeved to the position of sleeving the opening end 2120 of the first assembly arm 212, the membrane body center portion 231 of the waterproof sound permeable membrane 23 can be kept in a taut state.

[0094] In some embodiments, after the step (b.2), the membrane edge portion 232 of the waterproof acoustic membrane 23 is pulled in a direction away from the open end 2120 of the first assembly arm 212 to put the membrane central portion 231 of the waterproof acoustic membrane 23 in a taut state, and in the step (b.3), the pulling of the membrane edge portion 232 of the waterproof acoustic membrane 23 in the direction away from the open end 2120 of the first assembly arm 212 is continued to maintain the membrane central portion 231 of the waterproof acoustic membrane 23 in the taut state, so that after the sleeving ring 27 is sleeved to the position of the open end 2120 of the first assembly arm 212, the membrane central portion 231 of the waterproof acoustic membrane 23 can be maintained in the taut state.

[0095] In some embodiments, after the sleeving ring 27 is sleeved to the position of the open end 2120 of the first assembly arm 212, glue is applied between the sleeving ring 27 and the waterproof acoustic membrane 23 to bond the sleeving ring 27 and the waterproof acoustic membrane 23 by the glue.

[0096] In some embodiments, after the sleeving ring 27 is sleeved to the position of the open end 2120 of the first assembly arm 212, glue is applied between the sleeving ring 27 and the first assembly arm 212 to bond the sleeving ring 27 and the first assembly arm 212 by the glue.

[0097] In some embodiments, after the sleeving ring 27 is sleeved to the position of the open end 2120 of the first assembly arm 212, the riveting portion 28 is formed for riveting the first assembly arm 212, the waterproof acoustic membrane 23 and the sleeving ring 27.

[0098] Specifically, after the sleeve ring 27 is sleeved to the opening end 2120 of the first assembly arm 212, the positions of the glue injection perforations 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 and the positions of the glue injection grooves 2123 of the first assembly arm 212 correspond to the positions of the glue distribution grooves 272 of the sleeve ring 27, glue is injected through the glue injection port 271 of the sleeve ring 27, the glue is distributed to the glue injection perforations 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 and the glue injection grooves 2123 of the first assembly arm 212 through the glue distribution grooves 272 of the sleeve ring 27, and after the glue is solidified, the glue injection grooves 2123 of the first assembly arm 212, the glue injection perforations 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23, and the glue distribution grooves 272 and the glue injection port 271 of the sleeve ring 27 form the riveting portion 28 for riveting the first assembly arm 212, the waterproof sound permeable membrane 23, and the sleeve ring 27.

[0099] The sleeve ring 27 is sleeved to the opening end 2120 of the first assembly arm 212, and the glue injection perforations 2321 of the membrane body edge portion 232 of the waterproof sound permeable membrane 23 are aligned with the glue injection grooves 2123 of the first assembly arm 212. Figures 11 to 14 Another specific embodiment of the microphone device 20 of the respiratory mask according to the above preferred embodiment of the present application is shown in FIG. 6, which is different from the microphone device 20 shown in FIG. 5 in that the sleeve ring 27 is replaced by a sleeve ring 27' in FIG. 6. Figures 4 to 8 Another specific embodiment of the microphone device 20 of the respiratory mask according to the above preferred embodiment of the present application is shown in FIG. 6, which is different from the microphone device 20 shown in FIG. 5 in that the sleeve ring 27 is replaced by a sleeve ring 27' in FIG. 6. Figures 11 to 14 In this specific example of the microphone device 20, the microphone device 20 further comprises a support net 29 and a net plug ring 210, wherein the support net 29 comprises a net body central portion 291 and a net body edge portion 292 surrounding the net body central portion 291, the net body central portion 291 shields the assembly opening 2122 of the first assembly arm 212 of the assembly unit 21, and the net body edge portion 292 is sleeved to the opening end 2120 of the first assembly arm 212, wherein the net plug ring 210 is sleeved to the opening end 2120 of the first assembly arm 212, and the net body edge portion 292 of the support net 29 is clamped between the net plug ring 210 and the first assembly arm 212 to prevent the support net 29 from falling off the opening end 2120 of the first assembly arm 212. The membrane body central portion 231 of the waterproof sound permeable membrane 23 is supported by the net body central portion 291 of the support net 29, and the membrane body edge portion 232 surrounds the periphery of the net plug ring 210, wherein the sleeve ring 27 is sleeved to the net plug ring 210, and the membrane body edge portion 232 of the waterproof sound permeable membrane 23 is clamped between the sleeve ring 27 and the net plug ring 210 to prevent the waterproof sound permeable membrane 23 from falling off. Preferably, the net plug ring 210 and the first assembly arm 212 of the assembly unit 21 are bonded by glue.

[0100] That is, the microphone device 20 supports the waterproof sound permeable membrane 23 through the supporting net 29, and when the sound wave generated by the diver propagates to the microphone 22 through the waterproof sound permeable membrane 23, the supporting net 29 can control the amplitude of the waterproof sound permeable membrane 23, thereby preventing the waterproof sound permeable membrane 23 from being damaged due to large amplitude reciprocating vibration.

[0101] It can be understood that, after the net plug ring 210 is sleeved on the opening end 2120 of the first assembly arm 212 of the assembly unit 21, a clamping force can be provided between the net plug ring 210 and the first assembly arm 212 for clamping the net body edge portion 292 of the supporting net 29, so that the supporting net 29 is reliably arranged on the first assembly arm 212 of the assembly unit 21. Accordingly, after the sleeving ring 27 is sleeved on the net plug ring 210, a clamping force can be provided between the sleeving ring 27 and the net plug ring 210 for clamping the membrane body edge portion 232 of the waterproof sound permeable membrane 23, so that the membrane body center portion 23 of the waterproof sound permeable membrane 23 is reliably supported by the net body center portion 291 of the supporting net 29.

[0102] It can be understood that the shape of the inner wall of the sleeving ring 27 matches the shape of the outer wall of the net plug ring 210, so that the sleeving ring 27 and the net plug ring 210 can provide a clamping force in the entire circumferential direction of the membrane body edge portion 232 of the waterproof sound permeable membrane 23, to ensure that the assembly opening 2122 of the first assembly arm 212 of the assembly unit 22 is reliably sealed for retaining the microphone 22 in the waterproof space. For example, in this specific example of the breathing mouth cover of the present application, the sleeving ring 27 is a circular ring body, and the net plug ring 210 is also a circular ring body, so that the shape of the inner wall of the sleeving ring 27 matches the shape of the outer wall of the net plug ring 210.

[0103] Preferably, the inner diameter of the sleeving ring 27 is larger than the outer diameter of the net plug ring 210, and the inner diameter of the sleeving ring 27 is smaller than the sum of the outer diameter of the net plug ring 210 and twice the thickness of the membrane body edge portion 232 of the waterproof sound permeable membrane 23, so that, after the sleeving ring 27 is sleeved on the net plug ring 210, a clamping force can be provided between the sleeving ring 27 and the net plug ring 210 for clamping the membrane body edge portion 232 of the waterproof sound permeable membrane 23, to prevent the waterproof sound permeable membrane 23 from falling off the net plug ring 210.

[0104] After the supporting net 29 is arranged at the opening end 2120 of the first assembling arm 212 of the assembling unit 21, the plug ring 210 is pushed to be sleeved at the opening end 2120 of the first assembling arm 212 to avoid that the plug ring 210 applies a circumferential force to the supporting net 29. In this way, not only can the problem that the supporting net 29 is wrinkled or even torn be avoided, but also during the process that the plug ring 210 is pushed to be sleeved at the opening end 2120 of the first assembling arm 212, the plug ring 210 pulls the net body edge portion 292 of the supporting net 29 in a direction away from the opening end 2120 of the first assembling arm 212. In this way, the transition at the joint between the net body edge portion 292 and the net body center portion 291 of the supporting net 29 can be smoother, so that when the waterproof sound permeable membrane 23 is supported by the supporting net 29, the flatness of the waterproof sound permeable membrane 23 can be avoided to be affected by the supporting net 29, so as to ensure the sound collecting effect of the microphone device 20.

[0105] Correspondingly, after the membrane body center portion 231 of the waterproof sound permeable membrane 23 is supported by the net body center portion 291 of the supporting net 29 and the membrane body edge portion 232 is sleeved at the plug ring 210, the sleeving ring 27 is pushed to be sleeved at the plug ring 210. During the process that the sleeving ring 27 is pushed to be sleeved at the plug ring 210, the sleeving ring 27 is prevented from rotating relative to the plug ring 210, so as to avoid that the sleeving ring 27 applies a circumferential force to the waterproof sound permeable membrane 23. In this way, on the one hand, the problem that the waterproof sound permeable membrane 23 is wrinkled or even torn can be avoided, which is crucial for improving the yield of the microphone device 20. On the other hand, during the process that the sleeving ring 27 is pushed to be sleeved at the plug ring 210, the sleeving ring 27 pulls the membrane body edge portion 232 of the waterproof sound permeable membrane 23 in a direction away from the opening end 2120 of the first assembling arm 212. In this way, the membrane body center portion 231 of the waterproof sound permeable membrane 23 can be kept in a taut state, so as to ensure the sound collecting effect of the microphone device 20.
