Looking at the ball cover, it tastes a bit like manual Geng
Good idea
The national football refueling should be replaced by Geneva, refund
This must be a plot passing through the future. The sound insulation cover is written on the national football team.
The sound insulation cover generally needs a rough surface, increasing the number of sound reflections to achieve the sound insulation effect, so that you can't see the ball clearly, which is not convenient
It is proposed to turn the ventilation fan into an air pump, make the cover airtight and vacuum, so that the sound loses the medium, the sound insulation effect can be achieved, and the line of sight will not be blurred due to the rough surface of the sound insulation cover.
