Specific embodiment
In order to which the objects, technical solutions and advantages of utility model are more clearly understood, with reference to the accompanying drawings and embodiments,
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only practical new to explain
Type is not used to limit utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of high sound pressure orientation and amplifies waveguide bugle, and the high sound pressure is fixed
It is composed of to waveguide bugle is amplified two symmetrical bugle ontologies 100.The bugle ontology 100 includes main part 10 and sets
The partition group 20 being placed in main part 10, two main parts 10 are enclosed an inner cavity 11, and two partition groups 20 are connected to each other and will
Inner cavity 11 is divided into several subchannels.
The whole main part 10 is in horn-like setting, and the rear end forward end of main part 10 is in become larger setting.It is described
The rear end end of main part 10 is equipped with a mounting plate 14, extends outwardly on the inner side edge of main part 10 and is provided with mounting portion 15, institute
It states mounting portion 15 and is equipped with several mounting holes 16, the mounting hole 16 on two main parts 10 is corresponding, in order to use fastener will
Two main parts 10 are connected and fixed.The rear and front end of bugle ontology 100 is run through in the inner cavity 11, and in the front end of bugle ontology 100
Sound mouth 12 is formed, forms aditus laryngis 13 in the rear end of bugle ontology 100.The inner cavity 11 is by 13 one end of aditus laryngis to sound mouth 12 1
End is in become larger setting, and the arc-shaped setting of side wall of inner cavity 11.In the present embodiment, the rounded setting of the aditus laryngis 13, institute
It states sound mouth 12 to be square setting, and sound mouth 12 is aditus laryngis 13.
The partition group 20 in inner cavity 10 be equipped with first fork position A, second fork position B, third diverge position C and the 4th
Diverge position D, first fork position A, second fork position B, third fork position C and the 4th fork position D from aditus laryngis 13 to sound mouth 12 according to
It is secondary to be arranged side by side.The partition group 20 includes a main partition 21, two demarcation plates 22, twice partition 23 and six shuttle shape partitions 24.Institute
State the curvilinear setting in side of demarcation plate 22 and main partition 21 from aditus laryngis 13 to 12 direction of sound mouth, the secondary partition 23 and shuttle
Shape partition 24 is convexly curved setting from aditus laryngis 13 to the side in 12 direction of sound mouth, so as to increase the length of each subchannel
Degree.The main partition 21, demarcation plate 22 and secondary partition 23 are in hollow setting, and main partition 21, demarcation plate 22 and secondary partition 23 are equal
In structure setting broad in the middle small in ends.
Two demarcation plates 22 are respectively arranged at the two sides of main partition 21, wherein two demarcation plates 22 prolong from the first fork position A
It extends at sound mouth 12, the inner cavity 11 at the fork of aditus laryngis 13 to the first position A is separated into three equal parts by two demarcation plates 22.The master every
Plate 21 extends to the 4th place fork position D from the second fork position B, and main partition 21 and two demarcation plates 22 diverge position B to third for second
The inner cavity 11 of fork position C separates quarter.In the present embodiment, two demarcation plates 22 are arranged in willow leaf shape, and two demarcation plates 22 are in
Shape of filling the span of a man's arms is set to main 21 two sides of partition.
The two secondary partitions 23 are respectively arranged at the outside of two demarcation plates 22, and the secondary partition 23 prolongs from third fork position C
It extends at the 4th fork position D.Partition 23, two demarcation plates 22 and main partition 21 divide the inner cavity 11 of diverge position C to fork position D twice
It is divided into six equal portions.The six shuttle shape partitions 24 extend at sound mouth 12 from the 4th fork position D, and two demarcation plates 22 are by six
Shuttle shape partition 24 uniformly separates two-by-two, and two demarcation plates 22 and six shuttle shape partitions 24 diverge the 4th at position D to sound mouth 12
Chamber 11 is separated into nine equal portions and forms nine subchannels 17.Nine subchannel 17 is homogeneous to the overall length dimension of sound mouth 12 from aditus laryngis 13
Together, and width of each subchannel 17 at equal length position is also identical.So that the horizontal directivity of the bugle is wider, hang down
Direct at that tropism is very narrow and available control.Meanwhile acoustic pressure, sound more effectively can uniformly divide in the area of coverage and in necessary height
Cloth improves sound energy utilization efficiency;Directive property is optimized.
