Abstract
It include that main box, the top setting loudspeaker of main box and bottom end are provided with back cavity low frequency loudspeaker the utility model discloses a kind of back cavity low frequency loudspeaker speaker；Back cavity low frequency loudspeaker is provided with the vertebra angle that amplifies in loudspeaker back cavity；Low frequency radiation device is installed on the inside of main box, detachable shelf is provided on main tank body sidewall；Main box upper end is sequentially installed with foot pad, shelf, loudspeaker and lower cover from top to bottom.The utility model compares common speaker, back cavity low frequency loudspeaker increases the vertebra angle that amplifies in loudspeaker back cavity, the genial back cavity low frequency loudspeaker of complex sound collectively formed using air in cabinet and back cavity low frequency loudspeaker forms resonance, increase the directive property and extensibility of bass, so that bass auditory localization is more accurate, bass sensual pleasure is more clear.
Description
Technical field
The utility model relates to sound-box device technical field more particularly to a kind of back cavity low frequency loudspeaker speakers.
Background technique
Currently, most speaker systems all have cavity structure.Wherein the main function of back cavity is to prevent loudspeaker
The acoustic short circuit of low frequency, and low-frequency sound is made to have dynamics.Its height will be changed to existing woofer, reach certain again
Bass effect it is necessary to the thickness, the status again, wide that break through traditional loudspeaker design, solve the structure of existing product, vibration again
The design of dynamic system.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of back cavity low frequency expansion according to above-mentioned the deficiencies in the prior art
Sound device speaker.
The technical solution of the utility model is as follows:
A kind of back cavity low frequency loudspeaker speaker includes that main box, the top setting loudspeaker of main box and bottom end are set
It is equipped with back cavity low frequency loudspeaker；The back cavity low frequency loudspeaker is provided with the vertebra angle that amplifies in loudspeaker back cavity；On the inside of the main box
Low frequency radiation device is installed, is provided with detachable shelf on the main tank body sidewall；The main box upper end is from top to bottom successively
Foot pad, shelf, loudspeaker and lower cover are installed.
Further, the loudspeaker includes mask, gasket and loudspeaker.
Further, it is provided with and arranges net in the main box.
Further, the low frequency radiation device is at least provided with one.
Further, through-hole is provided on the lower lid；The foot pad is fixedly connected with the lower cover by the through-hole.
Compared with prior art, the utility model has the following beneficial effects: comparing common speaker, back cavity low frequency loudspeaker
The vertebra angle that amplifies is increased in loudspeaker back cavity, after the complex sound collectively formed using air in cabinet and back cavity low frequency loudspeaker is genial
Chamber low frequency loudspeaker forms resonance, increases the directive property and extensibility of bass, so that bass auditory localization is more accurate, bass
Sensual pleasure is more clear.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Figure 1-3, embodiment provided by the utility model, a kind of 9 speaker of back cavity low frequency loudspeaker, include main tank
Body 1, the top setting loudspeaker 11 of main box 1 and bottom end are provided with back cavity low frequency loudspeaker 9, and back cavity low frequency loudspeaker 9 exists
6 back cavity of loudspeaker is provided with the vertebra angle that amplifies.Loudspeaker 11 includes mask 4, gasket 5 and loudspeaker 6.
Low frequency radiation device 8 is installed on the inside of main box 1, detachable shelf 3 is provided on 1 side wall of main box；On main box 1
End is sequentially installed with foot pad 2, shelf 3, loudspeaker 11 and lower cover 7 from top to bottom.It is provided in main box 1 and arranges net 10.
For low frequency radiation device 8 at least provided with one, wherein there are two low frequency radiation devices 8 for setting in the present embodiment, and oppose
Setting is in 1 inside of main box.
Through-hole is provided on lower cover 7；The foot pad 2 is fixedly connected with the lower cover 7 by the through-hole.
Low frequency radiation device 8 and back cavity low frequency loudspeaker 9 combine the unstable sound for avoiding and reflecting acoustic aperture generation, i.e.,
Volume is set less can also to obtain good acoustic radiation effect, so high sensitivity, can effectively reduce 11 work range of loudspeaker,
Standing wave influence is small, and clear sound is transparent.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
