Embodiment
With reference to specific embodiment, the invention will be further described：
Referring to shown in attached drawing 1 to attached drawing 9, a kind of coaxial bugle of medium-high frequency, including bugle cylinder 1, be arranged in bugle cylinder 1
High-frequency phase plug 3 and the intermediate frequency phase plug 2 being set on bugle cylinder 1, intermediate frequency phase plug 2 include body 21, ring part 22 and circle
Platform 23, the ring part 22 around body 21 is formed with 21 lateral wall of body, while is provided with round platform 23 on the top of body 21, its
In, round platform 23 is hollow to cooperatively form the first inlet channel 24 with high-frequency phase plug 3, and the second inlet channel is provided with body 21
25, the second inlet channel 25 is extended transversely through to the import of the inside of body 21 and the second inlet channel 25 and opened in the top of ring part 22
Face；Bugle cylinder 1 is hollow, and the high-frequency phase plug 3 with being installed in bugle cylinder 1 forms one and speaks passage 11 for exporting intermediate frequency sound
Sound；First inlet channel 24 and the second inlet channel 25 are communicated with passage 11 of speaking, and length of the first inlet channel 24 etc.
In the length of the second inlet channel 25；
High-frequency phase plug 3 include being provided with housing 31 and housing 31 first into sound passage 32 with some second into sound
Passage 33, first joins end to end into sound passage 32 with second into sound passage 33 along 31 length direction of housing, and second into sound passage 32
It is used to export high-frequency sound along 31 width parallel arrangement of housing；First into 32 trapezoidal structure of sound passage, wherein, first into
The outlet connection second of sound passage 32 is into the import of sound passage 33, and first is less than second into sound into the entrance width of sound passage 32
The import of passage 33；Second is raised into the bending laterally of sound passage 33, and two adjacent second close middle into sound passage 33
Second into sound passage 33 bending degree of convexity than close 31 side of housing second into sound passage 33 bending degree of convexity
Greatly；Any sound from first into sound passage 32 to corresponding second into sound passage 33 total path length all same.
Wherein, several aluminium backings 26 are provided with body 21 it are used to support round platform 23 and (four pieces is provided with the present embodiment
Round platform 23, is then pasted onto on body 21 by aluminium backing 26 by glue etc.)；2 cross section of intermediate frequency phase plug is loop configuration；Number
Angle cylinder 1 be rectangular parallelepiped structure, and has diffusion type outlet 12 bugle cylinder 1 is end formed；First into sound passage 32 entrance
Equipped with a disk 311, a circular import is provided with disk 311；Second is raised (in shell into sound passage 33 to 31 both sides bending of housing
The front and rear two surface bending of body 31 is raised, therefore every second is divided into two into sound passage 33), and second into sound passage 33 be arc
Shape structure.
In the present embodiment, when the coaxial bugle of medium-high frequency works, intermediate frequency sound is respectively from the first inlet channel 24 and second
Inlet channel 25 enters, and then intermediate frequency sound converges output in passage 11 of speaking；And high-frequency sound is from first into sound passage 32
Into then being exported by second into sound passage 33, such intermediate frequency sound and high-frequency sound are in respective passage by therefore not
It can interfere with each other；
Wherein, intermediate frequency sound enters intermediate frequency phase plug 2 from the first inlet channel 24 and the second inlet channel 25 respectively, due to
The length of first inlet channel 24 is equal to the length of the second inlet channel 25, makes sound respectively from the first inlet channel 24 and second
Frequency is consistent after inlet channel 25 exports, and then the consistent sound of frequency converges carry out phase only pupil filter in the first inlet channel 21,
Enter back into speak and passage 11 and exported from diffusion type opening 12；
And in high-frequency phase plug 3, since first into sound passage 32 is trapezium structure, high-frequency sound is first into sound
The path length passed through in passage 32 is gradually incremented by from middle part to both sides, and second into sound passage 33 due to bending laterally,
Therefore sound gradually successively decreases second into the path length passed through in sound passage 33 from middle part to both sides, makes each sound by the
One into sound passage 32 with second into sound passage 33 total length it is consistent；Such as：First sound is first into the middle part of sound passage 32
By the shortest path of sound passage 32 (first into), subsequently into positioned at middle part second into the (length longest of sound passage 33
Two into sound passage 33), and second sound first into 32 outermost of sound passage by (first into sound passage 32 longest path
Footpath), subsequently on the outermost side second into sound passage 33 (length shortest second into sound passage 33), so make first
The total path length that sound passes through is identical with the total path length that second sound passes through.
The embodiment of the above is only presently preferred embodiments of the present invention, and limit in any form is not done to the present invention
System.Any those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Technology contents more possible variations and retouching are made to technical solution of the present invention, or be revised as the equivalence enforcement of equivalent variations
Example.Therefore all contents without departing from technical solution of the present invention, the equivalent equivalence changes that the thinking according to the present invention is made, should all cover
In in protection scope of the present invention.
