Technical realization elements: To solve at least one technical problem in the prior art. Therefore, technicians provide a dynamic microphone, which can stabilize the sound of the microphone by slowing down the circulation of a part of the gas. The moving coil microphone includes a shell. The shell is provided with an accommodation chamber, a channel, a second channel and a sound chamber. The first channel and the second channel are both connected to the accommodation chamber. The sound chamber is located under the accommodating chamber with the exhaust hole, and the voice coil assembly is arranged in the accommodating chamber and abuts against the side wall and the bottom wall of the accommodating chamber. The dynamic microphone has at least the following beneficial effects: by setting a channel and a vent, part of the air in the containing room is exhausted from a vent through the vibration of the voice coil assembly; by setting two channels and two vents, the containing room The other part of the air is guided from the two vents to the relatively closed sound chamber through the vibration of the voice coil assembly, and the mechanical waves carried by the air vibrate in the closed sound chamber without directly flowing out, thereby delaying. The housing includes a housing and a pickup housing, and the housing and the pickup housing are detachably connected to facilitate their assembly. The accommodating chamber is arranged in the housing, the sound chamber is arranged in the pickup housing, and the two exhaust holes are arranged at the bottom of the housing to facilitate the assembly of the pickup housing and the housing. The voice coil component includes a diaphragm, a coil, a magnetic column and a voice coil shell. The magnetic column and the coil are arranged in the voice coil shell; the sound wave is transmitted to the diaphragm, causing the diaphragm to vibrate, driving the coil to vibrate, cutting the magnetic field of the magnetic column, and the magnetic field of the magnetic column. The electromagnetic induction effect is produced, and the induced current is generated in the coil, so that the sound wave is converted into an electric signal. At the same time, the vibration of the diaphragm will drive the entire voice coil assembly to vibrate, so that part of the air in the accommodating room circulates to the first exhaust hole and the second exhaust hole, thereby achieving the effect of stabilizing the sound of the microphone.
