Description

Technical Field

[0001] The utility model belongs to the technical field of sound collection devices, and in particular relates to a sound collection device for short video production. Background Art

[0002] The application publication number of the related technology CN219960790U discloses a sound collection device for short video production, which is fixed to the rear of the intermediate support base by bolts, and the adjustment connection joint is installed at both ends of the intermediate support base through a damping shaft, and the shooting equipment bracket is installed at the top of the adjustment connection joint through a damping shaft; the sound source collection structure is installed at the bottom of the adjustment connection joint through a damping shaft. The setting of the intermediate support base and the sound source collection structure of the utility model will not appear in the camera, which can effectively isolate the sound made by the shooter.

[0003] This device has the effect of isolating the sound made by the photographer, but it cannot protect the microphone from dust after use. When the microphone is placed after use, it is mostly exposed to the air.
