The cover board of body one end and the second shell being threadedly coupled with the first shell other end, first shell include cylindrical shell portion and conical shell
Portion, loudspeaker are located in conical shell portion and are fixed by second shell.
Chinese Patent Application No.: 201820949384.5, disclose a kind of plane diaphragm loudspeaker, including ear muff, group of magnets
Part, diaphragm unit and rear cover, magnet assemblies include first support and the magnet that is fixed in first support, and diaphragm unit includes the
Two brackets and fixed diaphragm on the secondary support bracket, the ear muff, which is covered, to be covered to form a closed cavity, group of magnets after
Part and diaphragm unit are ensconced in closed cavity, and ear muff, magnet assemblies, diaphragm unit are successively aligned；The center of ear muff is provided with translucent
Hole, the sound that diaphragm unit is issued when ear muff fills in human ear external auditory canal enter the external auditory canal through penetrable sound hole.
Structure is complicated for foregoing invention creation, and there are blind area audition, sound timbre is poor.
Utility model content
The purpose of this utility model is that overcoming the drawbacks described above of the prior art, a kind of loudspeaker cavity body structure is provided.
To achieve the above object, the technical scheme that the utility model is provided is as follows: a kind of loudspeaker cavity body structure, including chamber
Body, cavity are in conical structure, and cavity bottom is equipped with bottom cover, is equipped with loudspeaker in cavity, cavity top ring concaved around cavity one week
Equipped with card slot, clamping at card slot is located above cavity and is equipped with reflection box, reflection box is in conical structure, and reflection box outer peripheral surface is around one
It offers several fan-shaped sound holes week, is recessed with slot respectively inwards on the outside of reflection box and cavity, EVA rubber strip is embedded in slot, instead
It penetrates arch and is additionally provided with EVA rubber top cover.
Further, passive Caloris Basin is additionally provided between cavity and bottom cover.
Further, bottom cover is equipped with wire casing.
Further, cavity material is kirsite.
The benificial effect of the utility model is to by rounding several fan-shaped sound holes opened up in reflection box outer peripheral surface,
Can within the scope of 360 ° non-blind area audition, passive Caloris Basin can increase cavity vibration volume and increase bass effect, by setting
Set EVA rubber can also audition and meanwhile play the role of damping caching reduce audio distortions.
Detailed description of the invention
Fig. 1 is a kind of configuration schematic diagram of loudspeaker cavity body structure of the utility model；
Fig. 2 is a kind of schematic cross-sectional view of loudspeaker cavity body structure of the utility model.
Specific embodiment
With reference to the accompanying drawing and preferred embodiment is further described with regard to the technical solution of the utility model.
As Figure 1-Figure 2, a kind of loudspeaker cavity body structure described in the utility model, including cavity 1, cavity 1 are in circular cone
Structure, 1 bottom of cavity are equipped with bottom cover 2, are equipped with loudspeaker 3 in cavity 1,1 top ring of cavity was concaved with card slot around cavity 1 one weeks
11, clamping at card slot 11 is located above cavity 1 and is equipped with reflection box 4, reflection box 4 is in conical structure, and 4 outer peripheral surface of reflection box is around one
Offer several fan-shaped sound holes 41 week, reflection box 4 and 1 outside of cavity are recessed with slot 141 respectively inwards, are embedded with EVA in slot 141
Rubber strip 142 is additionally provided with EVA rubber top cover 42 at the top of reflection box 4.
Further, passive Caloris Basin 5 is additionally provided between cavity 1 and bottom cover 2.
Further, bottom cover 2 is equipped with wire casing 21.
Further, 1 material of cavity is kirsite.
More than, this practical new construction is simple, by rounding several fan-shaped sound holes opened up in 4 outer peripheral surface of reflection box
41, non-blind area audition, passive Caloris Basin 5 it can increase cavity vibration volume within the scope of 360 ° and increase bass effect, lead to
Cross the EVA rubber that EVA rubber strip 142 is set and is arranged at the top of reflection box 4 in the recessed slot 141 of reflection box 4 and 1 outside of cavity
Glue top cover 42 can also play the role of simultaneously damping caching in audition and reduce audio distortions.
Above-described is only the principles of the present invention and preferred embodiment.It should be pointed out that the common skill of this field
For art personnel, without departing from the principle of this utility model, moreover it is possible to make several variations and modifications, also should be regarded as belonging to
In the protection scope of the utility model.
