Description
Technical field:
The present invention relates to a kind of band vane-type car horn and expand sound shell.
Background technology:
At present, car horn expands sound shell employing injection molding and becomes. Car horn is when coordinating whole car to assemble, due to the restriction of vehicle body space and position, car horn is normally assemblied in the position compared and expose, and traditional expansion sound shell is very easily intake and sand and dust when this position, cause speaker sound to change, thus cause loudspeaker not ring and lost efficacy.
Summary of the invention:
It is an object of the invention to provide the car horn of a kind of dust-proof structure of band vane-type and expand sound shell.
Above-mentioned object is realized by following technical scheme:
A kind of band vane-type car horn expands sound shell, and its composition comprises: car horn expands sound housing, one group of blade, and it is outside that described blade is hinged on described expansion sound shell in turn.
Described band vane-type car horn expands sound shell, and described expansion sound shell has the vane groove for stator blades, and described blade tip has and turns to cylinder, and the described cylinder that turns to is arranged in described vane groove.
Useful effect:
1. the car horn of the present invention expands sound shell, just defines the groove structure of rooting-inofblades after moulding, and one end of foil assembly is installed in vane groove structure in hinged way. Producing air-flow when loudspeaker work and blow blade, make the hinge point of blade axial rotation in groove, blade is overturn, the blinds that blade is formed is opened; When loudspeaker do not work, blade overturns downwards under gravity, superimposed successively, forms shielding, thus prevents entering of water and sand and dust. Can effectively improve the life-span of loudspeaker.
2. the sticky shell operation of the car horn of the present invention can adopt the full-automatic mode of production, decreases operation, reduces cost.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Embodiment:
Embodiment 1:
A kind of band vane-type car horn expands sound shell, and its composition comprises: car horn expands sound housing 1, one group of blade 2, and described blade is hinged on described expansion sound hull outside in turn.
Embodiment 2:
Band vane-type car horn according to embodiment 1 expands sound shell, and described expansion sound housing has the vane groove for stator blades, and described blade tip has and turns to cylinder, and the described cylinder that turns to is arranged in described vane groove.
Claims (1)
1.A kind of band vane-type car horn expands sound shell, its composition comprises: car horn expands sound housing, one group of blade, it is characterized in that: it is outside that described blade is hinged on described expansion sound shell in turn, described expansion sound shell has the vane groove for stator blades, described blade tip has and turns to cylinder, the described cylinder that turns to is arranged in described vane groove, car horn expands sound shell, just define the groove structure of rooting-inofblades after moulding, one end of foil assembly is installed in vane groove structure in hinged way, produce air-flow when loudspeaker work and blow blade, make the hinge point of blade axial rotation in groove, blade is overturn, the blinds that blade is formed is opened, when loudspeaker do not work, blade overturns downwards under gravity, superimposed successively, forms shielding, thus prevents entering of water and sand and dust, it is possible to the effective life-span improving loudspeaker.
