Abstract
The utility model discloses a kind of packing ring for installing horn trumpet, comprise circular coupling link, described coupling link has relative outer face and inner end surface, described outer face is provided with the screw for installing loudspeaker, the annular cavity of described coupling link is taper, and the diameter of annular cavity near inner end surface one end is greater than the diameter near outer face one end.The utility model effectively can strengthen the sound effect of loudspeaker.
Description
Technical field
The utility model relates to a kind of Car Audio accessory, more particularly, particularly relates to a kind of packing ring for installing horn trumpet.
Background technology
At present, horn trumpet is all be arranged on auto body (as car door) by a kind of special packing ring, because loudspeaker operationally can at the severe jolt of generation in the radial direction along packing ring, this vibration makes the annular cavity of packing ring produce air flowing.Its annular cavity of existing packing ring is substantially all cylindrical, and this columniform inner chamber is unfavorable for the flowing of air, has adverse influence to the sound effect of loudspeaker.
Utility model content
The technical problems to be solved in the utility model is: the deficiency existed for prior art, provides a kind of packing ring for installing horn trumpet that can strengthen loudspeaker stereo effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of packing ring for installing horn trumpet, comprise circular coupling link, described coupling link has relative outer face and inner end surface, described outer face is provided with the screw for installing loudspeaker, the annular cavity of described coupling link is taper, and the diameter of annular cavity near inner end surface one end is greater than the diameter near outer face one end.
As further improvement of the utility model:
The outer face of described coupling link is also provided with the tapped through hole for being installed to by coupling link on auto body.
The inner end surface of described coupling link extends outward expansion limit, and described expansion limit is provided with the tapped through hole for being installed to by coupling link on auto body.
Described expansion limit is annular arrangement.
Screw on described outer face is 16, and arranges along the circumferencial direction interval of outer face.
Described screw is the blind hole not penetrating coupling link.
Described coupling link is made up of aluminium.
Compared with prior art, the utility model has the advantage of: packing ring of the present utility model due to the annular cavity of its coupling link be taper, and the diameter of annular cavity near inner end surface one end is greater than the diameter near outer face one end, the air-flow that loudspeaker vibration produces can move smoothly through annular cavity more, makes the sound effect of loudspeaker better.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is side-looking structural representation of the present utility model.
In figure, each label is expressed as: 1, coupling link; 11, outer face; 12, inner end surface; 2, screw; 3, tapped through hole; 4, annular cavity; 5, limit is expanded.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail; should be understood that; protection domain of the present utility model is also not only confined to following embodiment; under the prerequisite not departing from the utility model principle; to any improvements and modifications done by the utility model, protection domain of the present utility model all should be considered as.
As shown in Figure 1 and Figure 2, packing ring for installing horn trumpet of the present utility model, comprise circular coupling link 1, coupling link 1 has relative outer face 11 and inner end surface 12, outer face 11 is provided with the screw 2 for installing loudspeaker, the annular cavity 4 of coupling link 1 is in taper, and the diameter of annular cavity 4 near inner end surface 12 one end is greater than the diameter near outer face 11 one end.During loudspeaker work, the air-flow that loudspeaker vibration produces can move smoothly through annular cavity 4 more, makes the sound effect of loudspeaker better.
In the present embodiment, the inner end surface 12 of coupling link 1 extends outward expansion limit 5, and expansion limit 5 is provided with the tapped through hole 3 for being installed to by coupling link 1 on auto body, and tapped through hole 3 is multiple, and arranges along the circumferential interval on expansion limit 5.In the occasion that auto body loudspeaker mounting hole is larger than coupling link 1 size, expansion limit 5 can cover loudspeaker mounting hole well, is convenient to the installation of coupling link 1.
In other embodiments, expansion limit 5 also can not be set, and directly arrange for coupling link 1 being installed to the tapped through hole 3 on auto body at the outer face 11 of coupling link 1.This form structure is more applicable for the auto body loudspeaker mounting hole occasion less than coupling link 1 size.
In the present embodiment, other shapes, in annular arrangement, certainly, also can be arranged to as required in expansion limit 5.
In the present embodiment, the screw 2 on outer face 11 is 16, and arranges along the circumferencial direction interval of outer face 11, and the situation that greatly can reduce the screw 2 of coupling link 1 not corresponding with loudspeaker mounting hole occurs, thus is applicable to the installation of all size loudspeaker.
In the present embodiment, screw 2 is the blind hole not penetrating coupling link 1.
In the present embodiment, coupling link 1 is made up of aluminium, certainly, also can be the other materials such as timber, plastics.
