Signal is filled with air or extraction air into inflation bar 3322, when wind resistance cover 3311 is accepted, substrate wind resistance ring 6,
Top wind resistance seat 7 and wind resistance ring 8 will be spliced into discoid on the substrate 31, so can preferably be bonded with substrate 31,
The longitudinal wind-force in front and back is avoided to blow to the problem on wind resistance cover 3311, then when needing to arch upward, it is only necessary to pass through air pump 3321
Inflated into inflation bar 3322, during inflating bar 3322 and inflating, inflation bar 3322 will elongation slowly, in turn
Top wind resistance seat 7 is pushed to move far from substrate 31, and during top wind resistance seat 7 moves, corresponding wind resistance ring 8 will be by
Pull-up, and since the diameter of wind resistance ring 8 is sequentially reduced, thus a pagoda shape will be constituted, as shown in figure 4, utilizing
Pagoda shape can effectively disperse wind, and then avoid in the prior art because of the overturning caused by wind blow-through of substrate 31
The problem of, and inflation bar 3322 and air pump 3321 cooperation used is used as power source, and when wind resistance cover 3311 is accepted, energy
Enough effective one smooth planes of formation on the substrate 31.
As a kind of improved specific embodiment, if the acoustic board 32 include vibration device 322, microphone 323 and
Dry vibrating reed 321, several described vibrating reeds 321 are evenly spaced in substrate 31 on the one side of wind resistance cover 3311, institute
