carrying out operation three;

when the recorder box 33 is started, the air intake fan 12 and the exhaust fan 3116 start to work synchronously, and the air intake fan 12 draws air from the outside, enters the air intake slot, passes through the first noise reduction body 13 and enters the interior of the protective shell 21;

the exhaust fan 3116 synchronously extracts the gas inside the protective casing 21, the gas inside the protective casing 21 passes through the sound-absorbing floor mat 312 and the ventilating screen plate 3111 to enter the second noise reduction body 3112, and then enters the gas collecting groove 3114 through the gas guide hole 3113, the air further enters the inside of the gas exchange ring groove 3115 through the guide groove, and the exhaust fan 3116 discharges the air entering the gas exchange ring groove 3115 out of the protective casing 21 through the exhaust groove;

carrying out operation four;

when recording is performed, sound waves diffused by the recording microphone 35 are absorbed by the sound absorbing layer 217, the sound absorbing floor mat 312 and the sound absorbing top plate 14, the first noise reducing body 13 absorbs noise emitted by the intake air fan 12, and the second noise reducing body 3112 absorbs noise emitted by the exhaust fan 3116;

meanwhile, the soundproof layer 212 cooperates with the vacuum layer 215 to prevent external noise from being transmitted into the interior of the protective casing 21, and also to prevent sound inside the protective casing 21 from being transmitted to the outside.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
