Preferably, also comprise the cushion pad that is arranged between described support and the fan.
Preferably, also comprise and be arranged on the buffer substrate tablet on the turning axle of fan between described fan and the fixed mount.
Preferably, also comprise the buffer bar that is arranged on described fixed mount top and/or bottom.
Preferably, described fan operation produces inertial force F, and described pickup groove is arranged on the frame bottom place that described inertial force F concentrates.
Preferably, described frame bottom place is 1/4 of a frame bottom length
Preferably, described cushion pad is arranged on the support inboard that is provided with described pickup groove diagonal angle.
Preferably, the length of described cushion pad is 1/2 of stent length.
Preferably, the width of described cushion pad equates with the width of fan.
In addition, also provide a kind of projector, comprise housing, be arranged on the projector's main body in the described housing, and the inboard above-mentioned projector fan of described housing is set.
At the pickup groove that frame bottom is provided with, it is provided with spring in this pickup groove, and this spring and fan apical grafting can reduce the vibration of generation when being moved by fan, reduce consequent noise.
Between support and fan, be provided with cushion pad, can reduce when moving and collision that support produces, reduce consequent noise by fan.
Because the strength ratio at the rotational symmetry center of fixed mount is lower, cause noise because of the vibration of fan easily, between the rotational symmetry center of fan and fixed mount, be provided with buffer substrate tablet, further reduce noise.
Be provided with buffer bar in cantilever tip and/or bottom, can reduce the collision of projector fan and projector's housing, further reduce noise.
Comparatively concentrate the place to be provided with pickup groove at frame bottom inertial force F, be provided with spring in this pickup groove, and be arranged on 1/4 place of frame bottom length, can reduce the vibration that produces by this inertial force F targetedly, reducing noise.
Same, cushion pad is arranged on the support inboard that is provided with the pickup groove diagonal angle, the vibration that is produced by this inertial force F over against the minimizing of property can be arranged, reducing noise.

[embodiment]
Consult Fig. 1, projector comprises housing, projector's main body and projector fan 100.Projector's main body is arranged in the housing, and this projector fan 100 is close to the madial wall that is arranged on housing, and is extremely outside the air dispatch by projector's main body.
Consult Fig. 2～4, in the present embodiment, be arranged side by side by two projector fans 100.This projector fan 100 comprises support 110, the fixed mount 130 that is housed in the fan 120 of support 110 inside and is connected to support 110 outsides.In other embodiments, this projector fan 100 also comprises the buffer bar 140 that is arranged on fixed mount 130 tops, be arranged on the cushion pad 150 between support 110 and the fan 120 and be arranged on fan 120 and fixed mount 130 between buffer substrate tablet 160.
Please in conjunction with consulting Fig. 5 to Fig. 8, support 110 tops are provided with the fixture block 111 of projection, and the location that is arranged on fixture block 111 both sides colludes 112, and the bottom is provided with positioning rib 114, and sidepiece is provided with trip 113.The bottom of support 110 also is provided with pickup groove 115, is provided with spring 116 in this pickup groove 115, this spring 116 and fan 120 apical graftings.Concrete, this pickup groove 115 is arranged on the right side (is the front with the support shown in the present embodiment accompanying drawing 8 110) of support 110 bottoms, at 1/4 place of support 110 length.
Please in conjunction with consulting Fig. 9～11, fixed mount 130 tops are provided with the hole clipping 131 with fixture block 111 couplings, collude the locating slot 132 of 112 couplings with the location, and sidepiece is provided with the draw-in groove 133 with trip 113 couplings.Simultaneously, also be provided with buffer substrate tablet 160 on the turning axle at fan between fan 120 and the fixed mount 130.Fixed mount 130 colludes 112 and corresponding respectively the fastening with hole clipping 131, locating slot 132 and draw-in groove 133 of trip 113 by fixture block 111, location, makes fixed mount 130 closely be fastened on the support 110.
