[0031] An installation hole 41 is arranged on the pipe wall of the connecting pipe 4, and the installation hole 41 is movably mounted with the pickup unit 3. In the specific implementation of the present application, the pickup unit is movably mounted with the installation hole to achieve the purpose of detachable mounting of the pickup unit. When the pickup unit is detached, a cover can be matched on the installation hole to achieve the purpose of sealing in the mask body.

[0032] The pickup unit 3 is provided with a mounting assembly for movably connecting with the installation hole. In the specific implementation of the present application, the mounting assembly is a buckle structure, which is matched with the installation hole to achieve the purpose of fixed mounting. Of course, the buckle structure is only one implementation, and the mounting method of matching the pickup device with the installation hole to achieve the purpose of fixed mounting is also within the protection scope of the present application.

[0033] The oxygen intake unit comprises an oxygen intake pipeline and an oxygen source, and the oxygen intake pipeline is fixedly connected with the lower end of the connecting pipe and the oxygen source.

[0034] The pickup unit 3 comprises a pickup shell 31, a connecting shell 32 and a loudspeaker shell 33 which are connected in sequence and are all in a cylindrical shape. One end of the pickup shell 31 is mounted with a pickup porous panel 311, and the other end is mounted with a first partition plate 312 to form an acoustic cavity 313. One end of the loudspeaker shell 33 is mounted with a loudspeaker porous panel 331, and the other end is mounted with a second partition plate 332 to form a loudspeaker cavity 333.

[0035] The acoustic cavity 313 is provided with a microphone circuit board 314 and at least one microphone assembly 315 connected to the microphone circuit board 314; the loudspeaker cavity 333 is provided with a loudspeaker assembly 334 and a power supply assembly 335, the loudspeaker assembly 334 is used to convert electrical signals into sound signals; the power supply assembly 335 is used to provide power support.

[0036] More specifically, the power supply assembly 335 includes a rechargeable battery and a charge management system for managing the charging and discharging process of the battery.

[0037] More specifically, the loudspeaker cavity is also provided with a signal processing unit connected to the microphone circuit board 314 through a wire, and the output end of the signal processing unit is connected to the loudspeaker assembly 334 through a wire, the signal processing unit includes the functions of amplification, filtering and digital processing of voice signals.

[0038] The acoustic cavity 313 is also provided with a first waterproof assembly 316, which is attached to the sound pickup porous panel 311; the loudspeaker cavity 333 is also provided with a second waterproof assembly 336, which is attached to the loudspeaker porous panel 331.

[0039] The first waterproof assembly 316 is an acoustic waterproof mesh cloth; the second waterproof assembly 336 is an acoustic waterproof mesh cloth or an acoustic mesh cloth.

[0040] More specifically, the microphone assembly 315 includes one microphone or a plurality of microphone arrays arranged in the acoustic cavity, the microphone is preferably a single directional electret condenser microphone, and can also be a directional or omnidirectional electret condenser microphone or a MEMS microphone. The single directional microphone helps to eliminate reverberation caused by reflected waves. The microphone can be cylindrical with a diameter of about 16mm or less. The microphone can also be rectangular. The microphone can be a single microphone or a group of microphone arrays, including but not limited to linear arrays, triangular arrays, circular arrays, or three-dimensional arrays, etc.

[0041] The microphone can be an air-conducted microphone or a bone-conducted microphone. The bone-conducted microphone needs to be closely attached to the structure so as to be able to pick up the vibration of the wearer's vocal cords and transmit the vibration to the oxygen mask.

[0042] The microphone or microphone array is located behind the sound pickup porous panel 311, and the porous material helps to reduce the propagation of airflow noise caused by breathing or speaking. The first waterproof component 316 is attached inside the sound pickup porous panel 311, further reducing noise such as wind noise and breathing airflow noise that is not conducive to voice communication. The microphone or microphone array should be placed 2mm or more behind the first waterproof component 316 to avoid turbulence caused by wind or airflow at the windproof cloth interface. Experiments have shown that placing the microphone behind the sound pickup porous panel 311 and the first waterproof component 316 has significant acoustic advantages, and this structure can effectively improve the clarity of speech. It is beneficial for weak sounds to be picked up by the microphone and amplified through the circuit and DSP for voice enhancement.

[0043] The acoustic cavity 313 is a sealed structure, except for the horn porous panel 331, which is sealed by the second partition plate and the connecting shell part, ensuring that the outside world is not connected to the acoustic cavity, shielding external noise and interfering speech, and reducing the self-speech played at the loudspeaker, i.e. achieving the effect of acoustic echo isolation.

[0044] The horn component 334 is preferably a loudspeaker with a diameter of 50mm or less, and a light and thin type with high sensitivity and low distortion is preferably selected. Such a loudspeaker can provide high-quality audio output in a limited space without significantly increasing the weight of the oxygen mask, ensuring the comfort of the wearer. In addition, the light and thin type loudspeaker can better adapt to the internal structure design of the oxygen mask and will not cause pressure to the wearer's head. A loudspeaker with high sensitivity can more efficiently convert electrical signals into acoustic signals, providing clear and loud sound output. Low distortion ensures audio quality, which will not produce significant distortion at high volume, and can ensure easier processing of echoes or howling by DSP or audio algorithms, improving the gain level of sound amplification.

[0045] The loudspeaker cavity 333 is designed as a closed box, so that the acoustic radiation direction is outward, reducing the echo path caused by unnecessary acoustic paths, and reducing the risk of howling. The closed box design limits the propagation path of sound waves, reducing the reflection and interference of sound waves in the oxygen mask, thereby improving the clarity and transmission efficiency of the audio. This design also prevents external noise from entering the helmet interior through the rear of the loudspeaker, further improving the upper limit of the ability of DSP or audio algorithms to process echoes and howling, and improving the quality and stability of voice communication.

[0046] The connecting shell 32 is provided with a sealing component 321, and when the connecting shell 32 passes through the mounting hole, the sealing component 321 is installed in interference fit with the mounting hole.

[0047] After the oxygen mask is worn by the wearer, the device is started, the microphone pickup device starts to pick up the voice signal of the wearer, and after being processed by the signal processing unit, the voice is played out by the sound playback system, realizing the intercom function.
