Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figs 1-4, a kind of loudspeaker accessory dust cap, including dust cap ontology 1 and sealing-plug 2；Dust cap ontology
1 is for the horn-like shell become larger that is open from inside to outside, dust cap ontology 1 includes speaker body 11 and lid 12；Loudspeaker
One end of ontology 11 has the first opening 111, the second opening 121 is offered on lid 12, sealing-plug 2 is for sealing the second opening
121；Sealing-plug 2 is equipped with concave part 21 towards the inside of speaker body 11；The inner surface of speaker body 11 offers several add
Strengthening tendons 3；Speaker body 11 and be located at first opening 111 outer surface be equipped with collar flange 112；Collar flange 112 includes
First collar flange 1121, the second collar flange 1122 and third collar flange 1123；First collar flange 1121, second
Relative size between collar flange 1122, third collar flange 1123 and the axis of dust cap ontology 1 successively becomes larger.
It is above to implement, specifically, including dust cap ontology 1 and sealing-plug 2；Dust cap ontology 1 is to open from inside to outside
The horn-like shell that mouth becomes larger, dust cap ontology 1 include speaker body 11 and lid 12；One end of speaker body 11 has
First opening 111 offers the second opening 121 on lid 12, and sealing-plug 2 is for sealing the second opening 121；So that dirt cap ontology
1 is adapted to the drum paper shape of loudspeaker well, it is ensured that the connection of dirt cap ontology 1 and drum paper installation is reliable, and sealing-plug 2 is set to second and opens
At mouth 121 and for closing the second opening 121, sealing-plug 2 is equipped with concave part 21 towards the inside of speaker body 11；And have
Since resonance degree is smaller, peak value is relatively low the sealing-plug 2 of concave part 21, can be accomplished in tracing pattern more satisfactory
Flatness, therefore using concave part 21 sealing-plug 2, with the loudspeaker of dust cap ontology 1 so that clear sound is bright, and
Also there is obvious mellow and full sense simultaneously.The inner surface of speaker body 11 offers several reinforcing ribs 3, and multiple reinforcing ribs 3 are around loudspeaker
The axis of ontology 11 is distributed in a ring；Reinforcing rib 3 extends to the second opening 121 from the first opening 111；It in this way can not only loudspeaker
The intensity of ontology 11 improves non-deformability, additionally it is possible to eliminate cutting edge of a knife or a sword side, prevent plowing from user；In addition speaker body 11 and
Outer surface positioned at the first opening 111 is equipped with collar flange 112；Collar flange 112 includes the first collar flange 1121, the
Two collar flanges 1122 and third collar flange 1123；First collar flange 1121, the second collar flange 1122, third ring
Relative size between shape flange 1123 and the axis of dust cap ontology 1 successively becomes larger.By by the first collar flange 1121 with
Relative size between the axis of dust cap ontology 1 is less than between the second collar flange 1122 and the axis of dust cap ontology 1
Relative size, while the relative size between the second collar flange 1122 and the axis of dust cap ontology 1 is convex less than third ring-type
Dust cap can be improved in the setting of relative size between edge 1123 and the axis of dust cap ontology 1, one side collar flange 112
Structural strength of the ontology 1 at the first beginning 11, on the other hand, when the drum paper of dust cap ontology 1 and loudspeaker is in mating connection,
The bonding strength for improving the drum paper junction of dust cap ontology 1 and loudspeaker, sealing caused by preventing dust cap ontology 1 from deforming are lost
Effect, while the first collar flange 1121, the second collar flange 1122, third collar flange 1123 are set, multistage dense may be implemented
It seals, form multiple sealed passages and hinder layer by layer, improve the sealing performance of dust cap, and then improve the service life of loudspeaker.It needs
Illustrate, dust cap ontology 1, sealing-plug 2；Collar flange 112 is integrally formed structures, and material can select silicon
Glue, integrally formed structure, which is arranged, ensures the leakproofness and integrality of dust cap, improves the structural strength of dust cap.
Optionally, sealing-plug 2 and dust cap ontology 1 are integrally formed, and structure is simple, easy to use, improve dust cap sheet
The intensity of body 1, while also ensuring the sealing performance of dust cap ontology 1, it can effectively prevent external dust, steam etc. from entering loudspeaker
Inside.
Optionally, speaker body 11 is gradually increased from the first opening 111 towards the curvature of curved surface of the second opening 121, so that
Entire dust cap ontology 1 has good sealing performance and elasticity.
Optionally, the surface of dust cap ontology 1 is coated with waterproof layer, so that dust cap ontology 1 has water-proof function, prevents
External moisture, which enters in loudspeaker, causes internal components to damage.
Optionally, the first collar flange 1121, the second collar flange 1122 and third collar flange 1123 are equipped with down
Angle, guiding role when being installed convenient for the drum paper in dust cap ontology 1 and loudspeaker.
The utility model is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from this reality
In the case where with novel spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.This reality
It is not limited to the particular embodiment disclosed with novel, other embodiments fallen into claims hereof all belong to
In the range of the utility model protection.
