Preferably, the waterproof sound-transmitting membrane 253 and the encasement ring 256 are bonded by glue. The encasement ring 256, the mesh plug ring 255 and the mounting cylinder 251 are bonded by glue.

It will be appreciated that after the net ring 255 is nested around the sound receiving end 2514 of the mounting cylinder 251 and the sound receiving end 2514 of the mounting cylinder 251, a clamping force may be provided between the net ring 255 and the mounting cylinder 251 to clamp the net body edge portion 2542 of the support net 254 such that the support net 254 is securely positioned at the sound receiving end 2514 of the mounting cylinder 251. Accordingly, after the encasement ring 256 is encased on the mesh plug ring 255, a holding force may be provided between the encasement ring 256 and the mesh plug ring 255 for holding the membrane body edge portion 2532 of the waterproof sound-transmitting membrane 253, such that the membrane body center portion 2531 of the waterproof sound-transmitting membrane 253 is reliably supported by the mesh body center portion 2541 of the support mesh 254.

Preferably, the shape of the inner wall of the mesh plug ring 255 matches the shape of the outer wall of the fitting cylinder 251 so that the mesh plug ring 255 and the fitting cylinder 251 can provide a clamping force in the entire circumferential direction of the mesh body edge portion 2542 of the support mesh 254 to ensure that the support mesh 254 is securely disposed at the sound receiving end 2514 of the fitting cylinder 251. The shape of the inner wall of the encasement ring 256 matches the shape of the outer wall of the mesh plug ring 255 such that the encasement ring 256 and mesh plug ring 255 can provide a clamping force in the entire circumferential direction of the membrane body rim portion 2532 of the waterproof sound-transmitting membrane 253 to ensure that the waterproof sound-transmitting membrane 253 reliably seals the sound-receiving opening 2512 of the fitting cylinder 251. For example, in this particular example of the respiratory nozzle cap of the present utility model, the mesh plug ring 255 and the encasement ring 256 are each a torus such that the shape of the inner wall of the encasement ring 256 matches the shape of the outer wall of the mesh plug ring 255.

Preferably, the inner diameter dimension of the sheathing ring 256 is larger than the outer diameter dimension of the mesh plug ring 255, and the inner diameter dimension of the sheathing ring 256 is smaller than the sum of the outer diameter dimension of the mesh plug ring 255 and the double thickness dimension of the membrane body edge portion 2532 of the waterproof sound-transmitting membrane 253, so that a clamping force can be provided between the sheathing ring 256 and the mesh plug ring 255 after the sheathing ring 256 is sheathed on the mesh plug ring 255 for clamping the membrane body edge portion 2532 of the waterproof sound-transmitting membrane 253, thereby preventing the waterproof sound-transmitting membrane 23 from falling off from the mesh plug ring 255.

In the microphone device 20 of the present utility model, after the support net 254 is disposed at the sound receiving end 2514 of the fitting cylinder 251, the net stopper 255 is pushed to the sound receiving end 2514 fitted to the fitting cylinder 251, so that the net stopper 255 is prevented from applying a force in the circumferential direction to the support net 254, in such a manner that not only the problem that the support net 254 is creased or even torn is avoided, but also the net stopper 255 pulls the net edge portion 2542 of the support net 254 toward the direction of the fitting end 2515 of the fitting cylinder 251, so that the junction of the net edge portion 2542 of the support net 254 and the net center portion 2541 can be more smooth, thereby preventing the turning of the waterproof sound-permeable membrane 253 to the support net 254 from affecting the sound-receiving effect of the microphone device 20 when the waterproof sound-permeable membrane 253 is supported to the support net 254.

Accordingly, after the membrane body central portion 2531 of the waterproof sound-transmitting membrane 253 is supported by the mesh body central portion 2541 of the support mesh 254 and the membrane body edge portion 2532 is wrapped around the mesh plug ring 255, the wrapping ring 256 is pushed to a position of the mesh plug ring 255, wherein the wrapping ring 256 is prevented from rotating relative to the mesh plug ring 255 during the pushing of the wrapping ring 256 to the wrapping of the mesh plug ring 255, thereby avoiding the problem that the wrapping ring 256 applies a circumferential force to the waterproof sound-transmitting membrane 253, on the one hand, the waterproof sound-transmitting membrane 253 is torn or even torn, which is critical for improving the yield of the microphone device 20, and on the other hand, the waterproof sound-transmitting membrane body edge portion 253 is pulled toward the mounting end 2515 of the mounting cylinder 2515 during the pushing of the wrapping ring 256, so that the waterproof sound-transmitting membrane 253 can be kept in a tight state by the microphone device 25, thereby ensuring that the waterproof sound-transmitting membrane 253 is kept in a tight state by the microphone device 31.

Fig. 13 shows another modified example of the microphone device 20 according to the above preferred embodiment of the present utility model, unlike the microphone device 20 shown in fig. 4 to 12, in this specific example of the microphone device 20 shown in fig. 13, the microphone assembly 25 is not provided with the support net 254 and the net plug 255.

That is, after the sheathing ring 256 is sheathed at the sound-receiving end 2514 of the fitting cylinder 251, a clamping force may be provided between the sheathing ring 256 and the fitting cylinder 251 for clamping the film body edge portion 2532 of the waterproof sound-transmitting film 253, so that the film body center portion 2531 of the waterproof sound-transmitting film 253 is held in a position to block the sound-receiving opening 2512 of the fitting cylinder 251, and thus the waterproof sound-transmitting film 253 can reliably seal the sound-receiving opening 2512 of the fitting cylinder 251.

It will be appreciated that the shape of the inner wall of collar 256 matches the shape of the outer wall of fitting cylinder 251 such that collar 256 and fitting cylinder 251 can provide a clamping force in the entire circumferential direction of waterproof acoustically transparent membrane 253 to ensure that waterproof acoustically transparent membrane 253 can reliably close the sound receiving opening 2512 of fitting cylinder 251. For example, in this particular example of the mouthpiece cover of the present utility model, the encasement ring 256 is a torus and the fitting cylinder 251 is a cylinder such that the shape of the inner wall of the encasement ring 256 matches the shape of the outer wall of the fitting cylinder 251.

Preferably, the inner diameter dimension of the sheathing ring 256 is larger than the outer diameter dimension of the fitting cylinder 251, and the inner diameter dimension of the sheathing ring 256 is smaller than the sum of the outer diameter dimension of the fitting cylinder 251 and the double thickness dimension of the film body edge portion 2532 of the waterproof sound-transmitting film 253, so that a clamping force can be provided between the sheathing ring 256 and the fitting cylinder 251 after the sheathing ring 256 is sheathed at the sound-receiving end 2514 of the fitting cylinder 251 for clamping the film body edge portion 2532 of the waterproof sound-transmitting film 253, preventing the waterproof sound-transmitting film 253 from falling off from the fitting cylinder 251.

Preferably, after the membrane body center portion 2531 of the waterproof sound-transmitting membrane 253 shields the sound-receiving opening 2512 and the membrane body edge portion 2532 of the fitting cylinder 251 from surrounding the sound-receiving end 2514 of the fitting cylinder 251, the grommet 256 is pushed to the sound-receiving end 2514 of the fitting cylinder 251 to avoid that the grommet 256 applies a circumferentially directed force to the waterproof sound-transmitting membrane 253, i.e. during the process of putting the grommet 256 on the sound-receiving end 2514 of the fitting cylinder 251, the grommet 256 is prevented from rotating relative to the fitting cylinder 251, thereby avoiding that the grommet 256 applies a circumferentially directed force to the waterproof sound-transmitting membrane 253, in such a way that on the one hand, the waterproof sound-transmitting membrane 253 is prevented from being torn or even torn, which is essential for improving the yield of the microphone device 20, on the other hand, the grommet 256 is prevented from being pulled towards the sound-receiving end 2514 of the fitting cylinder 251, and the waterproof sound-transmitting membrane 253 is kept in a state by the microphone device 25 in such a way that the sound-transmitting membrane body edge portion 2531 of the fitting cylinder 253 is kept in a tight state.

After the encasement ring 256 is encased on the sound receiving end 2514 of the fitting cylinder 251, glue is applied between the encasement ring 256 and the fitting cylinder 251 to allow the glue to bond the encasement ring 256 and the fitting cylinder 251, so that not only can the encasement ring 256 be prevented from falling off from the fitting cylinder 251, but also the water tightness between the encasement ring 256 and the fitting cylinder 251 can be increased, thereby ensuring the reliability of the microphone device 20. In this particular example of the microphone arrangement 20 shown in fig. 13, the membrane body edge portion 2532 of the waterproof sound-transmitting membrane 253 extends to the middle of the encasement ring 256 so that there is a gap between the encasement ring 256 and the fitting cylinder 251 into which glue applied between the encasement ring 256 and the fitting cylinder 251 is hidden to avoid protruding glue for bonding the encasement ring 256 and the fitting cylinder 251. In addition, after the encasement ring 256 is encaseed on the sound-receiving end 2514 of the mounting cylinder 251, glue may also be applied between the encasement ring 256 and the waterproof sound-transmitting membrane 253 to allow glue to bond the encasement ring 256 and the waterproof sound-transmitting membrane 253.
