In further technical scheme, the elastic spacing pivoted housing includes some elastic spacing pieces, each elastic spacing piece etc.
It is distributed in an annular region, isolation seam, each elastic spacing piece top is provided between two adjacent elastic spacing pieces
Medial surface be shaped to arc mating surface, each arc mating surface constitutes the resilient engagement hole.
In further technical scheme, the bottom of each elastic spacing piece is elastic portion, each elastic spacing piece
Top goes out one to inner side transverse fold can be connected along the location-plate of the radial direction resilient movement of the arbor, the bottom of elastic portion
Tie in the bottom surface of the knob installation cavity, location-plate inner face is the arc mating surface.
After said structure, the utility model is compared to the prior art advantageously：The utility model passes through
Design flexibility or elastic mechanism remove the arbor of spacing volume knob, make the limit on the rotating shaft of volume potentiometer/encoder and shell
Position hole keeps concentric co-axial automatically, so that it is tight and the bad problem such as scrape to eliminate sound volume button rotation feel.
