The special subwoofer is arranged in the sound equipment, the air duct is an indispensable part for bass, and the special subwoofer is mainly used for enabling the bass to be cleaner when the sound equipment is subjected to bass boosting.
However, most of the existing air guide pipes in the market are designed into a straight tubular shape, so that the air flow passing speed is high, strong full head-on force can generate vibration influence on an echo wall surface, the vibration can generate noise, and the mixed sound reduces the sound quality; meanwhile, the general air guide pipe has pertinence, namely, the mould opening is carried out independently aiming at different sizes, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a novel stereo set guide duct of cost-effective novel structure, noise are less, the sound effect of leading is better, functional stronger.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a novel stereo set guide duct, includes two bodys and arranges the connecting portion between the body in, and the body includes first body and second body, first body and second body are the straight tube-shape of one end, other end loudspeaker column structure, straight tube-shape port and connecting portion fixed connection, and the loudspeaker column port of first body is outer opening, and the loudspeaker column port of second body is interior opening, and the port of straight tube-shape can be dismantled and be connected with the loose ring, loose ring internal diameter is greater than the straight tube-end external diameter of body, still is equipped with annular boss on the loose ring inner wall, and outer open-ended diameter is greater than interior open-ended diameter, connecting portion are cylindric structure, and the port external diameter of connecting portion is less than the loose ring internal diameter.
Furthermore, the first pipe body is provided with raised lines on the outer wall of one side close to the outer opening, the raised lines are evenly distributed around the circle center of the outer opening, mounting holes are evenly distributed on the turned edge of the outer opening, and the number of the mounting holes is at least four.
Still further, connecting portion port department has seted up the bar breach, the activity ring with connecting portion be connected the inboard of one end be equipped with the card strip of bar breach looks adaptation, card strip embedding bar is in the breach.
And furthermore, the connecting part and the movable ring are connected by bonding, and the movable ring is bonded with the first pipe body and the second pipe body by using bonding agents.
Preferably, a plurality of through grooves are axially formed in the inner walls of the first pipe body and the second pipe body, and the width of each through groove is gradually narrowed from the opening to the bottom.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the design that two pipe bodies are combined into a group is adopted, namely an internal air guide pipe and an external air guide pipe group are included, and compared with a common single pipe body, the buffering effect on the flowing speed of air is further enhanced; meanwhile, the movable rings are additionally arranged on the two pipe bodies, the movable rings can be suitable for connecting parts of more models, independent die sinking is not needed for different models, and cost is greatly saved; an embedded design is arranged between the movable ring and the connecting part, so that the connecting stability can be further enhanced.

Detailed Description
The following embodiments of the present invention will be further described with reference to the accompanying drawings 1-6.
The concrete structure of the embodiment is as follows: including two bodys and arranging connecting portion 3 between the body in, the body is generally made by plastic material, and connecting portion 3 is generally made by the cardboard material, and connecting portion 3's length can increase or shorten according to particular case.
The body mainly includes first body 1 and second body 2, first body 1 and second body 2 are the straight tube-shape of one end, other end tubaeform structure, straight tube-shape port is used for with connecting portion 3 fixed connection, the tubaeform port of first body 1 is outer opening, the tubaeform port of second body 2 is interior opening, the port of straight tube-shape can be dismantled and be connected with loose ring 4, loose ring 4 internal diameter is greater than the straight tube-shape end external diameter of body, straight tube-shape port inlays inside loose ring 4 promptly, be equipped with annular boss 4a on loose ring 4 inner wall, annular boss 4 a's setting effect is in order to carry on spacingly to straight tube-shape port, after straight tube-shape port inserted loose ring 4 promptly, the port part just contradicts with annular boss 4a and is connected. The diameter of outer opening is greater than the diameter of interior opening, and connecting portion 3 is cylindric structure, and the port external diameter of connecting portion 3 is less than the internal diameter of activity ring 4.
In order to improve the connection stability of connecting portion 3 and activity ring 4, seted up bar breach 3a at connecting portion 3 port department, the inboard that one end was connected with connecting portion 3 to activity ring 4 is equipped with the card strip 4b with bar breach 3a looks adaptation, blocks in the strip 4b embedding bar breach 3 a. Meanwhile, after the connection is finished, the connection part 3 and the movable ring 4 are bonded by adopting viscose glue, and the movable ring 4 is bonded with the first pipe body 1 and the second pipe body 2 by adopting an adhesive.
Because smooth surface resistance is less, consequently all the axial is provided with a plurality of logical grooves 7 on first body 1 and 2 inner walls of second body, leads to the groove 7 width and narrows down to the bottom by opening part gradually, and such design can strengthen the buffer nature to the gas flow, reduces the noise, improves tone quality.
